How Much Does Paroxetine Cost in Mexico vs the USA?

Paroxetine tablets are indicated in adults for the treatment of: Major depressive disorder (MDD) Obsessive compulsive disorder (OCD) Panic disorder (PD) Social anxiety disorder (SAD) Generalized anxiety disorder (GAD) Posttraumatic stress disorder (PTSD) Paroxetine tablets are a selective serotonin reuptake inhibitor (SSRI) indicated in adults for the treatment of ( 1 ): Major Depressive Disorder (MDD) Obsessive Compulsive Disorder (OCD) Panic Disorder (PD) Social Anxiety Disorder (SAD) Generalized Anxiety Disorder (GAD) Posttraumatic Stress Disorder (PTSD)

Recommended starting and maximum daily dosage for MDD, OCD, PD, and PTSD: ( 2.2 ) Indication Starting Daily Dose Maximum Daily Dose MDD 20 mg 50 mg OCD 20 mg 60 mg PD 10 mg 60 mg PTSD 20 mg 50 mg Recommended starting dosage for SAD and GAD is 20 mg daily. ( 2.3 ) Elderly patients, patients with severe renal impairment or severe hepatic impairment: Starting dosage is 10 mg daily. Maximum dosage is 40 mg daily. ( 2.4 ) When discontinuing paroxetine tablets, reduce dosage gradually. ( 2.6 , 5.7 ) 2.1 Administration Information Administer paroxetine tablets as a single daily dose in the morning, with or without food. 2.2 Recommended Dosage for MDD, OCD, PD, and PTSD The recommended starting dosages and maximum dosages of paroxetine tablets in patients with MDD, OCD, PD, and PTSD are presented in Table 1. In patients with an inadequate response, increase dosage in increments of 10 mg per day at intervals of at least 1 week, depending on tolerability. Table 1: Recommended Daily Dosage of Paroxetine Tablets in Patients with MDD, OCD, PD, and PTSD Indication Starting Dose Maximum Dose MDD 20 mg 50 mg OCD 20 mg 60 mg PD 10 mg 60 mg PTSD 20 mg 50 mg 2.3 Recommended Dosage for SAD and GAD SAD The starting and recommended dosage in patients with SAD is 20 mg daily. In clinical trials the effectiveness of paroxetine tablets was demonstrated in patients dosed in a range of 20 mg to 60 mg daily. While the safety of paroxetine tablets has been evaluated in patients with SAD at doses up to 60 mg daily, available information does not suggest any additional benefit for doses above 20 mg daily [see Clinical Studies ( 14.4 )]. GAD The starting and recommended dosage in patients with GAD is 20 mg daily. In clinical trials the effectiveness of paroxetine tablets in GAD was demonstrated in patients dosed in a range of 20 mg to 50 mg daily. There is not sufficient evidence to suggest a greater benefit to doses higher than 20 mg daily [see Clinical Studies ( 14.5 )] . In patients with an inadequate response, increase dosage in increments of 10 mg per day at intervals of at least 1 week, depending on tolerability. 2.4 Screen for Bipolar Disorder Prior to Starting Paroxetine Tablets Prior to initiating treatment with paroxetine tablets or another antidepressant, screen patients for a personal or family history of bipolar disorder, mania, or hypomania [see Warnings and Precautions ( 5.6 )]. 2.5 Recommended Dosage for Elderly Patients, Patients with Severe Renal Impairment, and Patients with Severe Hepatic Impairment The recommended initial dosage is 10 mg per day for elderly patients, patients with severe renal impairment, and patients with severe hepatic impairment. Dosage should not exceed 40 mg/day. 2.6 Switching Patients to or From a Monoamine Oxidase Inhibitor (MAOI) At least 14 days must elapse between discontinuation of a monoamine oxidase inhibitor (MAOI and initiation of paroxetine tablets. In addition, at least 14 days must elapse after stopping paroxetine tablets before starting an MAOI antidepressant [see Contraindications ( 4 ), Warnings and Precautions ( 5.2 )] . 2.7 Discontinuation of Treatment With Paroxetine Tablets Adverse reactions may occur upon discontinuation of paroxetine tablets [see Warnings and Precautions ( 5.7 )]. Gradually reduce the dosage rather than stopping paroxetine tablets abruptly whenever possible.

Paroxetine tablets are contraindicated in patients: Taking, or within 14 days of stopping, MAOIs (including the MAOIs linezolid and intravenous methylene blue) because of an increased risk of serotonin syndrome [see Warnings and Precautions ( 5.2 ), Drug Interactions ( 7 )]. Taking thioridazine because of risk of QT prolongation [see Warnings and Precautions ( 5.3 ), Drug Interactions ( 7 )] Taking pimozide because of risk of QT prolongation [see Warnings and Precautions ( 5.3 ), Drug Interactions ( 7 )]. With known hypersensitivity (e.g., anaphylaxis, angioedema, Stevens-Johnson syndrome) to paroxetine or any of the inactive ingredients in paroxetine tablets [see Adverse Reactions ( 6.1 ), ( 6.2 )] . Concomitant use of monoamine oxidase inhibitors (MAOIs) or use within 14 days of discontinuing a MAOI. ( 4 , 5.3 , 7 ) Concomitant use of pimozide or thioridazine. ( 4 , 5.3 , 7 ) Known hypersensitivity to paroxetine or to any of the inactive ingredients in paroxetine tablets. ( 4 )

Serotonin Syndrome: Increased risk when co-administered with other serotonergic agents, but also when taken alone. If occurs, discontinue paroxetine tablets and serotonergic agents and initiate supportive measures. ( 5.2 ) Embryofetal Toxicity: May cause fetal harm. Meta-analyses of epidemiological studies have shown increased risk (less than 2-fold) of cardiovascular malformations with exposure during the first trimester. ( 5.4 , 8.1 ) Increased Risk of Bleeding : Concomitant use of aspirin, nonsteroidal anti-inflammatory drugs, other antiplatelet drugs, warfarin, and other anticoagulant drugs may increase risk. ( 5.5 ) Activation of Mania/Hypomania : Screen patients for bipolar disorder. ( 5.6 ) Seizures : Use with caution in patients with seizure disorders. ( 5.8 ) Angle-Closure Glaucoma : Angle-closure glaucoma has occurred in patients with untreated anatomically narrow angles treated with antidepressants. ( 5.9 ) Sexual Dysfunction: Paroxetine tablets may cause symptoms of sexual dysfunction. ( 5.13 ) 5.1 Suicidal Thoughts and Behaviors in Adolescents and Young Adults In pooled analyses of placebo-controlled trials of antidepressant drugs (SSRIs and other antidepressant classes) that included approximately 77,000 adult patients and 4,500 pediatric patients, the incidence of suicidal thoughts and behaviors in antidepressant-treated patients age 24 years and younger was greater than in placebo-treated patients. There was considerable variation in risk of suicidal thoughts and behaviors among drugs, but there was an increased risk identified in young patients for most drugs studied. There were differences in absolute risk of suicidal thoughts and behaviors across the different indications, with the highest incidence in patients with MDD. The drug-placebo differences in the number of cases of suicidal thoughts and behaviors per 1,000 patients treated are provided in Table 2. Table 2: Risk Differences of the Number of Patients with Suicidal Thoughts and Behaviors in the Pooled Placebo-Controlled Trials of Antidepressants in Pediatric and Adult Patients Age Range Drug-Placebo Difference in Number of Patients with Suicidal Thoughts and Behaviors per 1,000 Patients Treated Increases Compared to Placebo <18 years old 14 additional cases 18-24 years old 5 additional cases Decreases Compared to Placebo 25-64 years old 1 fewer case ≥65 years old 6 fewer cases Paroxetine tablets are not approved for use in pediatric patients. It is unknown whether the risk of suicidal thoughts and behaviors in children, adolescents, and young adults extends to longer-term use, i.e., beyond four months. However, there is substantial evidence from placebo-controlled maintenance trials in adults with MDD that antidepressants delay the recurrence of depression and that depression itself is a risk factor for suicidal thoughts and behaviors. Monitor all antidepressant-treated patients for any indication for clinical worsening and emergence of suicidal thoughts and behaviors, especially during the initial few months of drug therapy, and at times of dosage changes. Counsel family members or caregivers of patients to monitor for changes in behavior and to alert the healthcare provider. Consider changing the therapeutic regimen, including possibly discontinuing paroxetine tablets, in patients whose depression is persistently worse, or who are experiencing emergent suicidal thoughts or behaviors. 5.2 Serotonin Syndrome SSRIs, including paroxetine tablets, can precipitate serotonin syndrome, a potentially life-threatening condition. The risk is increased with concomitant use of other serotonergic drugs (including triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, meperidine, methadone, tryptophan, buspirone, amphetamines and St. John’s Wort) and with drugs that impair metabolism of serotonin, i.e., MAOIs [see Contraindications ( 4 ), Drug Interactions ( 7.1 )] . Serotonin syndrome can also occur when these drugs are used alone. Serotonin syndrome symptoms may include mental status changes (e.g., agitation, hallucinations, delirium, and coma), autonomic instability (e.g., tachycardia, labile blood pressure, dizziness, diaphoresis, flushing, hyperthermia), neuromuscular symptoms (e.g., tremor, rigidity, myoclonus, hyperreflexia, incoordination), seizures, and/or gastrointestinal symptoms (e.g., nausea, vomiting, diarrhea). The concomitant use of paroxetine tablets with MAOIs is contraindicated. In addition, do not initiate paroxetine tablets in a patient being treated with MAOIs such as linezolid or intravenous methylene blue. No reports involved the administration of methylene blue by other routes (such as oral tablets or local tissue injection) or at lower doses. If it is necessary to initiate treatment with an MAOI such as linezolid or intravenous methylene blue in a patient taking paroxetine tablets discontinue paroxetine tablets before initiating treatment with the MAOI [see Contraindications ( 4 ), Drug Interactions ( 7 )] . Monitor all patients taking paroxetine tablets for the emergence of serotonin syndrome. Discontinue treatment with paroxetine tablets and any concomitant serotonergic agents immediately if the above symptoms occur, and initiate supportive symptomatic treatment. If concomitant use of paroxetine tablets with other serotonergic drugs is clinically warranted, inform patients of the increased risk for serotonin syndrome and monitor for symptoms. 5.3 Drug Interactions Leading to QT Prolongation The CYP2D6 inhibitory properties of paroxetine can elevate plasma levels of thioridazine and pimozide. Since thioridazine and pimozide given alone produce prolongation of the QTc interval and increase the risk of serious ventricular arrhythmias, the use of paroxetine tablets is contraindicated in combination with thioridazine and pimozide [see Contraindications ( 4 ), Drug Interactions ( 7 ), Clinical Pharmacology ( 12.3 )]. 5.4 Embryofetal Toxicity Based on meta-analyses of epidemiological studies, exposure to paroxetine in the first trimester of pregnancy is associated with a less than 2-fold increase in the rate of cardiovascular malformations among infants. For women who intend to become pregnant or who are in their first trimester of pregnancy, paroxetine tablets, should be initiated only after consideration of the other available treatment options [see Use in Specific Populations ( 8.1 )]. 5.5 Increased Risk of Bleeding Drugs that interfere with serotonin reuptake inhibition, including paroxetine tablets, increase the risk of bleeding events. Concomitant use of aspirin, nonsteroidal anti-inflammatory drugs (NSAIDS), other antiplatelet drugs, warfarin, and other anticoagulants may add to this risk. Case reports and epidemiological studies (case-control and cohort design) have demonstrated an association between use of drugs that interfere with serotonin reuptake and the occurrence of gastrointestinal bleeding. Based on data from the published observational studies, exposure to SSRIs, particularly in the month before delivery, has been associated with a less than 2-fold increase in the risk of postpartum hemorrhage [see Use in Specific Populations ( 8.1 )] . Bleeding events related to drugs that interfere with serotonin reuptake have ranged from ecchymoses, hematomas, epistaxis, and petechiae to life-threatening hemorrhages. Inform patients about the increased risk of bleeding associated with the concomitant use of paroxetine tablets and antiplatelet agents or anticoagulants. For patients taking warfarin, carefully monitor the international normalized ratio. 5.6 Activation of Mania or Hypomania In patients with bipolar disorder, treating a depressive episode with paroxetine tablets or another antidepressant may precipitate a mixed/manic episode. During controlled clinical trials of paroxetine tablets, hypomania or mania occurred in approximately 1% of paroxetine tablets-treated unipolar patients compared to 1.1% of active-control and 0.3% of placebo-treated unipolar patients. Prior to initiating treatment with paroxetine tablets, screen patients for any personal or family history of bipolar disorder, mania, or hypomania. 5.7 Discontinuation Syndrome Adverse reactions after discontinuation of serotonergic antidepressants, particularly after abrupt discontinuation, include: nausea, sweating, dysphoric mood, irritability, agitation, dizziness, sensory disturbances (e.g., paresthesia, such as electric shock sensations), tremor, anxiety, confusion, headache, lethargy, emotional lability, insomnia, hypomania, tinnitus, and seizures. A gradual reduction in dosage rather than abrupt cessation is recommended whenever possible [see Dosage and Administration ( 2.7 )]. During clinical trials of GAD and PTSD, gradual decreases in the daily dose by 10 mg/day at weekly intervals followed by 1 week at 20 mg/day was used before treatment was discontinued. The following adverse reactions were reported at an incidence of 2% or greater for paroxetine tablets and were at least twice that reported for placebo: Abnormal dreams, paresthesia, and dizziness adverse reactions have been reported upon discontinuation of treatment with paroxetine tablets in pediatric patients. The safety and effectiveness of paroxetine tablets in pediatric patients have not been established [see Boxed Warning, Warnings and Precautions ( 5.1 ), Use in Specific Populations ( 8.4 )]. 5.8 Seizures Paroxetine tablets have not been systematically evaluated in patients with seizure disorders. Patients with history of seizures were excluded from clinical studies. During clinical studies, seizures occurred in 0.1% of patients treated with paroxetine tablets. Paroxetine tablets should be prescribed with caution in patients with a seizure disorder. Discontinue paroxetine tablets in any patient who develops seizures. 5.9 Angle-Closure Glaucoma The pupillary dilation that occurs following use of many antidepressant drugs including paroxetine tablets may trigger an angle closure attack in a patient with anatomically narrow angles who does not have a patent iridectomy. Cases of angle-closure glaucoma associated with use of paroxetine tablets have been reported. Avoid use of antidepressants, including paroxetine tablets in patients with untreated anatomically narrow angles. 5.10 Hyponatremia Hyponatremia may occur as a result of treatment with SSRIs, including paroxetine tablets. Cases with serum sodium lower than 110 mmol/L have been reported. Signs and symptoms of hyponatremia include headache, difficulty concentrating, memory impairment, confusion, weakness, and unsteadiness, which may lead to falls. Signs and symptoms associated with more severe and/or acute cases have included hallucination, syncope, seizure, coma, respiratory arrest, and death. In many cases, this hyponatremia appears to be the result of the syndrome of inappropriate antidiuretic hormone secretion (SIADH). In patients with symptomatic hyponatremia, discontinue paroxetine tablets and institute appropriate medical intervention. Elderly patients, patients taking diuretics, and those who are volume-depleted may be at greater risk of developing hyponatremia with SSRIs [see Use in Specific Populations ( 8.5 )]. 5.11 Reduction of Efficacy of Tamoxifen Some studies have shown that the efficacy of tamoxifen, as measured by the risk of breast cancer relapse/mortality, may be reduced with concomitant use of paroxetine tablets as a result of paroxetine’s irreversible inhibition of CYP2D6 and lower blood levels of tamoxifen [see Drug Interactions ( 7 )] . One study suggests that the risk may increase with longer duration of coadministration. However, other studies have failed to demonstrate such a risk. When tamoxifen is used for the treatment or prevention of breast cancer, prescribers should consider using an alternative antidepressant with little or no CYP2D6 inhibition. 5.12 Bone Fracture Epidemiological studies on bone fracture risk during exposure to some antidepressants, including SSRIs, have reported an association between antidepressant treatment and fractures. There are multiple possible causes for this observation, and it is unknown to what extent fracture risk is directly attributable to SSRI treatment. 5.13 Sexual Dysfunction Use of SSRIs, including paroxetine tablets, may cause symptoms of sexual dysfunction [see Adverse Reactions ( 6.1 )] . In male patients, SSRI use may result in ejaculatory delay or failure, decreased libido, and erectile dysfunction. In female patients, SSRI use may result in decreased libido and delayed or absent orgasm. It is important for prescribers to inquire about sexual function prior to initiation of paroxetine tablets and to inquire specifically about changes in sexual function during treatment, because sexual function may not be spontaneously reported. When evaluating changes in sexual function, obtaining a detailed history (including timing of symptom onset) is important because sexual symptoms may have other causes, including the underlying psychiatric disorder. Discuss potential management strategies to support patients in making informed decisions about treatment.

Table 9 presents clinically significant drug interactions with paroxetine tablets. Table 9: Clinically Significant Drug Interactions with Paroxetine Tablets Monoamine Oxidase Inhibitors (MAOIs) Clinical Impact The concomitant use of SSRIs, including paroxetine tablets, and MAOIs increases the risk of serotonin syndrome. Intervention Paroxetine tablets are contraindicated in patients taking MAOIs, including MAOIs such as linezolid or intravenous methylene blue [see Dosage and Administration ( 2.5 ), Contraindications ( 4 ), Warnings and Precautions ( 5.2 )] . Examples selegiline, tranylcypromine, isocarboxazid, phenelzine, linezolid, methylene blue Pimozide and Thioridazine Clinical Impact Increased plasma concentrations of pimozide and thioridazine, drugs with a narrow therapeutic index, may increase the risk of QTc prolongation and ventricular arrhythmias. Intervention Paroxetine tablets are contraindicated in patients taking pimozide or thioridazine [see Contraindications ( 4 )]. Other Serotonergic Drugs Clinical Impact The concomitant use of serotonergic drugs with paroxetine tablets increases the risk of serotonin syndrome. Intervention Monitor patients for signs and symptoms of serotonin syndrome, particularly during treatment initiation and dosage increases. If serotonin syndrome occurs, consider discontinuation of paroxetine tablets and/or concomitant serotonergic drugs [see Warnings and Precautions ( 5.2 )] . Examples other SSRIs, SNRIs, triptans, tricyclic antidepressants, opioids, lithium, tryptophan, buspirone, amphetamines, and St. John’s Wort. Drugs that Interfere with Hemostasis (antiplatelet agents and anticoagulants) Clinical Impact The concurrent use of an antiplatelet agent or anticoagulant with paroxetine tablets may potentiate the risk of bleeding. Intervention Inform patients of the increased risk of bleeding associated with the concomitant use of paroxetine Tablets and antiplatelet agents and anticoagulants. For patients taking warfarin, carefully monitor the international normalized ratio [see Warnings and Precautions ( 5.5 )] . Examples aspirin, clopidogrel, heparin, warfarin Drugs Highly Bound to Plasma Protein Clinical Impact Paroxetine tablets are highly bound to plasma protein. The concomitant use of paroxetine tablets with another drug that is highly bound to plasma protein may increase free concentrations of paroxetine tablets or other tightly-bound drugs in plasma . Intervention Monitor for adverse reactions and reduce dosage of paroxetine Tablets or other protein-bound drugs as warranted. Examples Warfarin Drugs Metabolized by CYP2D6 Clinical Impact Paroxetine tablets are a CYP2D6 inhibitor [see Clinical Pharmacology ( 12.3 )]. The concomitant use of paroxetine tablets with a CYP2D6 substrate may increase the exposure of the CYP2D6 substrate. Intervention Decrease the dosage of a CYP2D6 substrate if needed with concomitant paroxetine Tablets use. Conversely, an increase in dosage of a CYP2D6 substrate may be needed if paroxetine tablets are discontinued. Examples propafenone, flecainide, atomoxetine, desipramine, dextromethorphan, metoprolol, nebivolol, perphenazine, tolterodine, venlafaxine, risperidone. Tamoxifen Clinical Impact Concomitant use of tamoxifen with paroxetine tablets may lead to reduced plasma concentrations of the active metabolite (endoxifen) and reduced efficacy of tamoxifen Intervention Consider use of an alternative antidepressant with little or no CYP2D6 inhibition [see Warnings and Precautions ( 5.11 )]. Fosamprenavir/Ritonavir Clinical Impact Co-administration of fosamprenavir/ritonavir with paroxetine Tablets significantly decreased plasma levels of paroxetine Tablets. Intervention Any dose adjustment should be guided by clinical effect (tolerability and efficacy). Drugs Highly Bound to Plasma Protein : Monitor for adverse reactions and reduce dosage of paroxetine tablets or other protein-bound drugs (e.g., warfarin) as warranted. ( 7 ) Drugs Metabolized by CYP2D6 : Reduce dosage of drugs metabolized by CYP2D6 as warranted. ( 7 ) Concomitant use with tamoxifen : Consider use of an alternative antidepressant with little or no CYP2D6 inhibition. ( 5.11 , 7 )

PTSD In a fixed-dose study comparing placebo and paroxetine tablets 20 mg and 40 mg in the treatment of PTSD, the following adverse reactions were shown to be dose-dependent: impotence and abnormal ejaculation. Male and Female Sexual Dysfunction Although changes in sexual desire, sexual performance, and sexual satisfaction often occur as manifestations of a psychiatric disorder, they may also be a consequence of SSRI treatment. However, reliable estimates of the incidence and severity of untoward experiences involving sexual desire, performance, and satisfaction are difficult to obtain, however, in part because patients and healthcare providers may be reluctant to discuss them. Accordingly, estimates of the incidence of untoward sexual experience and performance cited in labeling may underestimate their actual incidence. The percentage of patients reporting symptoms of sexual dysfunction in males and females with MDD, OCD, PD, SAD, GAD, and PTSD are displayed in Table 8. Table 8.

Because these reactions are reported voluntarily from a population of unknown size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Acute pancreatitis, elevated liver function tests (the most severe cases were deaths due to liver necrosis, and grossly elevated transaminases associated with severe liver dysfunction), Guillain-Barré syndrome, Stevens-Johnson syndrome, toxic epidermal necrolysis, drug reaction with eosinophilia and systemic symptoms (DRESS), syndrome of inappropriate ADH secretion, prolactinemia and galactorrhea; extrapyramidal symptoms which have included akathisia, bradykinesia, cogwheel rigidity, oculogyric crisis which has been associated with concomitant use of pimozide; status epilepticus, acute renal failure, pulmonary hypertension, allergic alveolitis, anosmia, hyposmia, anaphylaxis, eclampsia, laryngismus, optic neuritis, porphyria, restless legs syndrome (RLS), ventricular fibrillation, ventricular tachycardia (including torsade de pointes), hemolytic anemia, events related to impaired hematopoiesis (including aplastic anemia, pancytopenia, bone marrow aplasia, and agranulocytosis), vasculitic syndromes (such as Henoch-Schönlein purpura), and premature births in pregnant women. There has been a case report of severe hypotension when paroxetine tablets were added to chronic metoprolol treatment.

8.1 Pregnancy Risk Summary Based on data from published observational studies, exposure to SSRIs, particularly in the month before delivery, has been associated with a less than 2-fold increase in the risk of postpartum hemorrhage [see Warnings and Precautions ( 5.5 ) and Clinical Considerations] . Paroxetine tablets are associated with a less than 2-fold increase in cardiovascular malformations when administered to a pregnant woman during the first trimester. While individual epidemiological studies on the association between paroxetine use and cardiac malformations have reported inconsistent findings, some meta-analyses of epidemiological studies have identified an increased risk of cardiovascular malformations (see Data). There are risks of persistent pulmonary hypertension of the newborn (PPHN) (see Data) and/or poor neonatal adaptation with exposure to selective serotonin reuptake inhibitors (SSRIs), including paroxetine tablets during pregnancy. There also are risks associated with untreated depression in pregnancy (see Clinical Considerations). For women who intend to become pregnant or who are in their first trimester of pregnancy, paroxetine should be initiated only after consideration of the other available treatment options. No evidence of treatment related malformations was observed in animal reproduction studies, when paroxetine was administered during the period of organogenesis at doses up to 50 mg/kg/day in rats and 6 mg/kg/day in rabbits. These doses are approximately 8 (rat) and less than 2 (rabbit) times the maximum recommended human dose (MRHD – 60 mg) on an mg/m 2 basis. When paroxetine was administered to female rats during the last trimester of gestation and continued through lactation, there was an increase in the number of pup deaths during the first four days of lactation. This effect occurred at a dose of 1 mg/kg/day which is less than the MRHD on an mg/m 2 basis ( See Data ). The background risks of major birth defects and miscarriage for the indicated populations are unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the US general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Clinical Considerations Disease-associated maternal and/or embryofetal risk Women who discontinue antidepressants during pregnancy are more likely to experience a relapse of major depression than women who continue antidepressants. This finding is from a prospective, longitudinal study of 201 pregnant women with a history of major depressive disorder who were euthymic and taking antidepressants at the beginning of pregnancy. Consider the risk of untreated depression when discontinuing or changing treatment with antidepressant medication during pregnancy and the postpartum. Maternal Adverse Reactions Use of paroxetine tablets in the month before delivery may be associated with an increased risk of postpartum hemorrhage [see Warnings and Precautions ( 5.5 )] . Fetal/Neonatal adverse reactions Neonates exposed to paroxetine tablets and other SSRIs late in the third trimester have developed complications requiring prolonged hospitalization, respiratory support, and tube feeding. Such complications can arise immediately upon delivery. Reported clinical findings have included respiratory distress, cyanosis, apnea, seizures, temperature instability, feeding difficulty, vomiting, hypoglycemia, hypotonia, hypertonia, hyperreflexia, tremors, jitteriness, irritability, and constant crying. These findings are consistent with either a direct toxic effect of SSRIs or possibly a drug discontinuation syndrome. It should be noted that, in some cases, the clinical picture is consistent with serotonin syndrome [see Warnings and Precautions ( 5.2 )] . Data Human Data Published epidemiological studies on the association between first trimester paroxetine use and cardiovascular malformations have reported inconsistent results; however, meta-analyses of population-based cohort studies published between 1996 – 2017 indicate a less than 2-fold increased risk for overall cardiovascular malformations. Specific cardiac malformations identified in two meta-analyses include an approximately 2 to 2.5-fold increased risk for right ventricular outflow tract defects. One meta-analysis also identified an increased risk (less than 2-fold) for bulbus cordis anomalies and anomalies of cardiac septal closure, and an increased risk for atrial septal defect (pooled OR 2.38, 95% CI 1.14-4.97). Important limitations of the studies included in these meta-analyses include potential confounding by indication, depression severity, and potential exposure misclassification. Exposure to SSRIs, particularly later in pregnancy, may have an increased risk for PPHN. PPHN occurs in 1-2 per 1,000 live births in the general population and is associated with substantial neonatal morbidity and mortality. Animal Data Reproduction studies were performed at doses up to 50 mg/kg/day in rats and 6 mg/kg/day in rabbits administered during organogenesis. These doses are approximately 8 (rat) and less than 2 (rabbit) times the maximum recommended human dose (MRHD – 60 mg) on an mg/m 2 basis. These studies have revealed no evidence of developmental effects. However, in rats, there was an increase in pup deaths during the first 4 days of lactation when dosing occurred during the last trimester of gestation and continued throughout lactation. This effect occurred at a dose of 1 mg/kg/day which is less than the MRHD on an mg/m 2 basis. The no effect dose for rat pup mortality was not determined. The cause of these deaths is not known.
