Bringing medication to Puerto Rico: what to pack and how
Bringing medication to Puerto Rico is simplest in your carry-on, in labeled original containers, with enough for the whole trip plus a few extra days. The TSA allows pills and medically necessary liquids once you tell the officer. If you forget or lose a non-controlled medicine, our doctor can see you by video while you are on the island.

- Chest pain, shortness of breath or signs of a stroke: call 911
- Swelling of the face or throat, or trouble breathing after a medicine: call 911
- Someone took the wrong medicine or too much: call Poison Help, 1-800-222-1222

Bringing medication to Puerto Rico: the basics
The CDC's advice on traveling with medicine works for an island trip too:
- Pack your medicines in your carry-on, not your checked bag.
- Keep them in their original labeled containers, with your name, your doctor's name, the generic name and the dose.
- Bring enough for the whole trip plus a few extra days in case of delays.
- Carry copies of your prescriptions with each medicine's generic name, and leave a copy with someone at home.
A photo of each label and a medication list on your phone will save you if something goes missing.
Medication on the plane: TSA rules
According to the TSA, pills and solid medications are allowed in carry-on and checked bags.
Liquid medications that you need are allowed in reasonable quantities for your trip, even over 3.4 ounces, but you must tell the officer at the checkpoint. Insulin is allowed in carry-on and checked bags too: tell the officer and place it in a separate bin for screening.
The final decision at the checkpoint rests with the TSA officer. Arriving by ship? See the cruise passenger guide.
Insulin and other medicines in the island heat
The CDC warns that extreme temperatures can make medicines less effective. In Puerto Rico, a car parked in the sun or a beach bag gets very hot.
According to the FDA, unopened insulin is stored in the refrigerator (36 °F to 46 °F). A vial or cartridge can be kept unrefrigerated, between 59 °F and 86 °F, for up to 28 days. Keep it away from direct heat and sunlight, and don't use insulin that has been frozen.

Controlled substances: bring enough
We do not prescribe controlled substances, including replacements for ones left at home. If you take a controlled medicine (for pain, anxiety, sleep or attention, for example), bring enough for the whole trip plus a few extra days, and ask the doctor who prescribes it what to do if it gets lost.
If you forgot or lost a medicine
If the medicine is not controlled and you already take it, our doctor can see you by video in a US$49 follow-up visit: anyone can book one for a refill. See lost prescription in Puerto Rico and how a prescription refill works.
You see Dr. Diana Nieves Castro, a Puerto Rico-licensed general practice physician with several years of emergency-department experience, in English or Spanish. If appropriate, the doctor prescribes and we send your prescription to your pharmacy. Have the bottle, a photo of the label or your medication list ready.
Some pharmacy chains can move a prescription from one store to another; if yours has stores on the island, ask the pharmacy directly how it works. To find a pharmacy counter open at night, see 24-hour pharmacies in Puerto Rico.
How the visit works and what it costs
Request a visit online 24/7 — we confirm your time by email or text. We send you a secure video link. It works on your phone, tablet or computer. You need to be physically in Puerto Rico during the visit, and visitors are welcome: see our care for tourists and visitors.
Book a visit and choose Follow-up visit (US$49) for a refill, or Doctor visit (US$79) for a new problem. If a follow-up visit turns out to need a full doctor visit, the doctor explains why and, only with your consent, you pay the difference. We do not bill insurance; on request we give you an itemized receipt (superbill). If the patient is under 21, a parent or legal guardian stays on camera for the whole visit and shows photo ID.
How we care for you
We evaluate, diagnose and treat; if needed, we give you a lab order for a lab near you.
We see adults and children of all ages. Patients under 21: a parent with patria potestad (parental authority) or a legal guardian is on camera for the whole visit and shows photo ID.
Real-time video visit. We send you a secure video link. It works on your phone, tablet or computer.
If appropriate, the doctor prescribes and we send your prescription to your pharmacy. We do not prescribe controlled substances.
