Flying into Mérida Mexico with medication
The best advice is quite simple with only 2 things to remember:
Carry a copy of the prescription or physician’s letter of the medication you are bringing with you.
If you do not have either one of these, keep the pills in the bottle that lists the medication. Most of us place our pills in a weekly pill container but this is not advisable when entering the country.
You are allowed to bring enough medicine for the time period you will be in Mérida.
If you will be in Mérida for 3 weeks, have enough medicine for 3 weeks plus a few days extra in the event of an emergency.
If you are bringing an unusual quantity of medication to Mérida, bring a doctor’s prescription. This situation would apply in the event you need to prove the medicine is for your own consumption OR in case your medicine is NOT available in Mérida. Most doctors are happy to provide a prescription for you to bring with you.
Avoiding a lot of hassle and stress at the border is key.

Local tips if you run out of medication in Mérida Mexico
As long as you have your prescription, you should be able to get it filled in Mérida. This is another reason to bring your prescription with you.
Here’s what you can do if you find you’ve run out of, lost or damaged your medication:
- Not all pharmacies are the same.
- Some pharmacies will carry your medication and others will not.
- You may find your medication at one pharmacy but the same brand pharmacy across town does not carry it.
- Find a pharmacy close to you and take in your prescription, if available.
- There are times when I’ve not had my prescription but I did have the packaging or bottle the medication came in. This sufficed for a refill. While this worked for me, it may or may not work for you.
- If you don’t have your prescription, some pharmacies have someone on-site that can write one for you.
- I stay away from the discount pharmacies like Pharmacias Similares. I’ve not had a good experience with them even though the medication is extremely cheap.
- Don’t give up! If you can’t find your medication, continue to search. I’ve had the most luck with Farmacias del Ahorra at Plaza Grande. Google Farmacias del Ahorra Parque Central. It is located on the corners of Calle 62 and Calle 63.
