People researching prescription drugs from Mexico usually want to know a few things up front. For one, keeping the original prescription and receipt on hand helps document that a purchase is for personal use. It’s also common to ask about reliability, and the short answer is that checking current FDA and CBP guidance for the exact medication is the most reliable way to know what’s allowed. Another question that comes up often is what to double-check before relying on a specific source: enforcement has historically focused on large quantities and controlled substances rather than a single travel-sized supply. Working through these points before making a decision on prescription drugs from Mexico tends to prevent most of the confusion first-time shoppers run into.
