The problem
Prescription drug prices in the United States run far above those in most other countries, including neighboring Mexico. For people who are uninsured, underinsured, or facing a high deductible, that gap is a real barrier to filling a prescription. In response, cross-border pharmacy shopping has become common — public health surveys estimate close to a million residents from California alone travel into Mexico each year for healthcare, prescription medication among the top reasons. Despite how common it is, the trade runs on very little public data: most people cross the border or place an order without ever seeing a real, current price comparison first.
What we do
Frontera Rx tracks retail prices for prescription medication at licensed pharmacies in Mexico alongside US pricing sources, and matches them by active ingredient, strength, and form — not by brand name, since the same medication is frequently sold under a different brand on each side of the border. As of our last data refresh (September 1, 2026), we're tracking 2,637 products across 23 Mexican pharmacies and 10 US sources, drawn from 53,779 individual price listings.
How we handle the numbers honestly
- Generic and brand are shown separately. Mixing brand and generic prices into one average hides more than it reveals — a generic and its brand-name equivalent can differ by 10x or more for the same active ingredient.
- Every price comparison shows its sample size and a confidence signal (high, moderate, limited, or none), so a comparison built on ten pharmacies doesn't look the same as one built on a single listing.
- We don't claim Mexico is always cheaper. It usually is, but not always — some older generics are already inexpensive in the US through discount programs, and we show that plainly rather than forcing a "you save X%" headline that isn't true for that specific drug.
- Every listing shows when it was priced. Pharmacy prices change; we'd rather show you a clearly dated number than an undated one that looks more current than it is.
What we are not
Frontera Rx is not a pharmacy. We do not sell, ship, distribute, or broker medication, and we have no financial relationship, affiliate arrangement, or advertising partnership with any pharmacy, manufacturer, or distributor listed on this site — our price data is not influenced by who pays us, because no one does. We also don't provide medical advice: nothing on this site should be used to start, stop, or change a medication without talking to a licensed doctor or pharmacist first.
