Taking semaglutide to Mexico

Mexico requires you to carry a valid prescription or doctor's letter whenever you travel with semaglutide, and customs officers may ask to see it at the port of entry. Semaglutide is registered in Mexico under its international brand names (Ozempic, Wegovy, Rybelsus) and regulated by COFEPRIS, Mexico's national health authority. Mexico City's summer temperatures and the country's varied climate zones create real cold-chain risks for injectable formulations, planning your storage before departure is essential.^[1]

Before you travel

Documentation for travelling to Mexico with semaglutide

Passengers travelling with semaglutide must carry a medical prescription or a doctor's letter that specifies the quantity needed for the duration of the trip, according to Mexican customs rules. The letter must be signed by your prescribing physician and include their contact details and professional registration number. Review Mexico's medication import rules before departure to confirm you have everything in order.^[1]

Pre-travel semaglutide paperwork timeline

T-30 days
Confirm supply for the full trip. Mexico has had on-and-off Ozempic shortages since 2023; do not plan to refill semaglutide locally without a backup plan.
T-14 days
Get a prescriber letter in English and Spanish naming semaglutide (INN), brand (Ozempic, Wegovy, or Rybelsus), dose, weekly schedule, and indication. COFEPRIS requires prescription-only dispensing for all semaglutide formulations.Spanish-translated prescription
T-7 days
Source an insulated travel pouch and a small ice pack to keep injectable semaglutide between 2°C and 8°C in transit. Rybelsus tablets do not need refrigeration.
T-1 day
Pack semaglutide in original packaging in carry-on (never checked baggage — hold temperatures drop below freezing). Keep cold pack ready.
T-0 (border)
Carry-on only. Mexican customs rarely opens medications, but the prescription and prescriber letter cover you if asked. Refrigerate at 2–8°C immediately on arrival.

What your doctor's letter must include

Full name of the patient. Medication name: generic (semaglutide) and brand (Ozempic, Wegovy, or Rybelsus). Dose and frequency. Total quantity being carried. Diagnosis or condition (one word is sufficient). Doctor's full name, signature, contact telephone and address, and professional registration number. Print on clinic letterhead. A Spanish translation is strongly recommended, Mexican customs officers are not required to accept documents in other languages.

A Spanish translation of your prescription or letter is strongly advisable, since customs officers at Mexican ports of entry are not obliged to process documents in other languages. No notarisation or apostille is required for personal-use medication documentation under current COFEPRIS rules.^[2]

How much semaglutide to bring

The quantity you bring must not exceed what your prescription or doctor's letter documents as necessary for your trip. Semaglutide is not a controlled substance under COFEPRIS classification, so there is no fixed maximum-day cap enforced for personal-use importation, but carrying a conspicuously large supply relative to your trip length may prompt additional scrutiny. Bring at least one extra dose as a buffer for delays, missed doses due to travel disruption, or a damaged pen. Confirm with your insurer whether a replacement supply purchased in Mexico will be reimbursed before you depart.^[1]

Split your supply

Carry your primary supply in your hand luggage and pack one backup dose in your checked luggage, in original packaging with pharmacy labels intact. If one bag is lost or delayed, you still have medication. Keep a photograph of the label and your doctor's letter saved offline on your phone.

Packing and storing semaglutide for travel

Unopened semaglutide pens must be refrigerated at 2°C to 8°C until first use and must never be frozen, exposure to freezing temperatures permanently degrades the medication. For transit, use an insulated cold-chain travel wallet with ice packs, keeping pens away from direct contact with ice to avoid accidental freezing. Keep all pens in their original carton with the pen cap on to protect from light. During layovers or long waits in warm terminals, request refrigeration at an airline lounge or ask your gate agent for assistance.^[4]

At the airport and border

Airport security with semaglutide

Injectable semaglutide pens are medical liquids and are exempt from the standard 100 ml cabin liquid restriction under IATA medical exemption rules, carry them in your hand luggage with your doctor's letter accessible. Declare the pens and any accompanying needles proactively to the security officer before scanning. Needles and pen tips are permitted in hand luggage when they accompany the prescribed medication and a supporting medical letter. A gel ice pack keeping your pens cool is also permissible in hand luggage when accompanying medication, rules vary by departure airport, so confirm at check-in.

Customs and medication import rules for Mexico

Upon entering Mexico, you must declare any prescription medication to customs authorities and be prepared to present your doctor's letter or prescription on request. Mexico operates an automated red-light/green-light inspection system, if a red light appears, your bags will be searched and undeclared medications may be questioned. Semaglutide is not listed on Mexico's controlled substance schedules (Lista Roja or Lista Amarilla), so no COFEPRIS import permit is required for personal-use quantities. Keep all pens in original manufacturer packaging with pharmacy labels attached to confirm authenticity and personal-use intent.^[1]^[3]

Keep original packaging

Semaglutide is not a controlled substance under COFEPRIS, so no special import permit is required for personal use. However, removing pens from original packaging can create problems at customs. Always travel with pens in their original carton, pharmacy label intact, and carry a digital and printed copy of your doctor's letter. If customs officers query your medication, show the letter calmly and state: 'Este medicamento es de uso personal bajo prescripción médica.'

While in country

Semaglutide availability in Mexico

Semaglutide brands available in Mexico

Brand	Manufacturer	Formulation	Approved indication	Supply
Ozempic	Novo Nordisk	Once-weekly subcutaneous injection (0.25 mg, 0.5 mg, 1 mg, 2 mg pens)	Type 2 diabetes	Intermittent — recurrent national shortages since 2023; private hospital pharmacies most reliable
Wegovy	Novo Nordisk	Once-weekly subcutaneous injection (higher doses than Ozempic, up to 2.4 mg)	Obesity / chronic weight management	Limited — late-2024 Mexico launch; available mainly through specialty clinics
Rybelsus	Novo Nordisk	Once-daily oral tablet (3 mg, 7 mg, 14 mg)	Type 2 diabetes	More reliable than Ozempic in Mexico; private pharmacies stock consistently

Ozempic was repeatedly out of stock at major Mexican chains throughout 2023–2024 as global supply tightened. Wegovy launched in Mexico in late 2024 but distribution is still uneven. Build a backup plan with your prescriber before travelling.

Ozempic and Wegovy are available in Mexico under the same international brand names, manufactured by Novo Nordisk and distributed through authorised pharmacy chains. Rybelsus (oral semaglutide) is also available at major chains. Ozempic pens typically cost approximately MXN 2,750 to MXN 5,200 (~$160 to ~$300 / ~€145 to ~€275) per pen depending on dose and pharmacy location, with Wegovy ranging from approximately MXN 3,000 to MXN 8,000 (~$175 to ~$465 / ~€160 to ~€425). A local prescription from a licensed Mexican physician is legally required to purchase semaglutide at a pharmacy, though enforcement varies between establishments.^[5]^[6]

Stock shortages are a real risk

Demand for semaglutide across Mexico has outpaced supply at certain doses in 2025 and 2026, particularly for Wegovy. Contact your target pharmacy chain in advance, or ask your hotel concierge to call ahead. Farmacia San Pablo, Farmacia Guadalajara, and Benavides are the most consistently stocked major chains. Avoid purchasing from small independent pharmacies or online sources, where counterfeit medication is a documented risk.

Finding a doctor who can prescribe semaglutide in Mexico

Private endocrinologists and internal medicine physicians in major cities such as Mexico City, Guadalajara, and Monterrey can issue a local prescription for semaglutide. English-speaking specialists are available in private hospitals and medical centres in tourist areas and large cities. A private consultation typically costs MXN 800 to MXN 2,000 (~$46 to ~$116 / ~€43 to ~€108). Telemedicine platforms operating in Mexico can also provide a consultation and prescription, which you can then present at a pharmacy.

Storing semaglutide while in Mexico

Mexico City has a moderate climate, but coastal and low-altitude destinations such as Cancún, Puerto Vallarta, and Los Cabos regularly exceed 35°C in summer, well above the 30°C maximum for semaglutide room-temperature storage. After first use, an Ozempic pen may be kept at room temperature up to 30°C for up to 56 days, and a Wegovy pen for up to 28 days, but temperatures above 30°C risk degrading the medication. In any hotel, ask reception to store your unopened pens in the in-room mini-fridge or, if absent, at the front desk refrigerator, most hotels accommodate this on request. Do not store pens in a parked car or luggage left in a hot vehicle, as temperatures inside can exceed 40°C within minutes.^[4]

Emergencies

What to do if something goes wrong with your semaglutide in Mexico

If your medication is lost or stolen, contact your travel insurer immediately and file a police report (denuncia) at the nearest ministerio público, your insurer will likely require this to process a replacement claim. If a pen has been exposed to heat above 30°C or has been frozen, do not use it, visible cloudiness or particles in the solution indicate degradation.

If you run out unexpectedly, go to a Farmacia San Pablo, Farmacia Guadalajara, or Benavides branch in the nearest city and present your original prescription or doctor's letter. If you cannot obtain medication without a local prescription, visit a private clinic or book a telemedicine consultation, a Mexican doctor can issue a prescription the same day.

“”

Mexico's single emergency number is 911, covering ambulance, police, and fire services across the country. For urgent medical care, private hospitals such as Hospital Ángeles, Médica Sur, or Hospital ABC in Mexico City have English-speaking staff and can manage medication-related emergencies without the delays common in public facilities.

Frequently asked questions

Can I bring semaglutide into Mexico?

Yes. Semaglutide is not a controlled substance under COFEPRIS and can be brought into Mexico for personal use. You must carry a valid prescription or doctor's letter stating your name, medication, dose, and the quantity required for your trip, and be prepared to declare it at customs.^[1]

Is semaglutide available in Mexican pharmacies?

Yes. Ozempic, Wegovy, and Rybelsus are all available at major Mexican pharmacy chains under the same international brand names. A local prescription from a licensed Mexican physician is legally required, though enforcement varies by pharmacy. Stock can be inconsistent at higher doses, so contact the pharmacy ahead of your visit.^[6]

Do I need a doctor's letter to fly with semaglutide?

A doctor's letter is required by Mexican customs rules to enter the country with prescription medication, and it is strongly advisable at airport security when carrying injectable pens and needles. The letter must include your name, the medication's generic and brand name, dose, frequency, quantity, and your doctor's registration number and signature.

What if I run out of semaglutide in Mexico?

Visit a private clinic or book a same-day telemedicine consultation with a licensed Mexican physician to obtain a local prescription, then purchase at a major pharmacy chain such as Farmacia San Pablo or Farmacia Guadalajara. Ozempic pens typically cost MXN 2,750 to MXN 5,200 (~$160 to ~$300 / ~€145 to ~€275) per pen out of pocket.

Does the heat in Mexico affect my semaglutide?

Yes. Temperatures above 30°C degrade injectable semaglutide and can render it ineffective. Coastal Mexican destinations regularly exceed this threshold. Store unopened pens in your hotel mini-fridge, use an insulated travel wallet with ice packs in transit, and never leave pens in a parked vehicle.^[5]

Is semaglutide a controlled substance in Mexico?

No. COFEPRIS classifies semaglutide as a prescription-only medication, not as a controlled substance. It does not appear on Mexico's Lista Roja or Lista Amarilla of controlled substances, so no special import permit beyond a standard prescription or doctor's letter is required for personal-use quantities.
