What are the rules for bringing medications into Mexico?

When bringing medications into Mexico, keep them in their original containers with clear labels showing your name, the prescribing doctor, and dosage instructions. Whenever possible, carry a copy of your prescription, especially for strong medications. Only bring the amount necessary for your stay, as large quantities may raise concerns at customs.

Some common over-the-counter drugs from the US or Canada, like those containing pseudoephedrine or codeine, are restricted or banned in Mexico, so check ahead to avoid issues.
