Migraine in Costa Rica: Triptans, CGRP Drugs and Tropical Heat
Costa Rica's tropical heat, altitude changes, and pharmacy landscape create specific planning needs for migraine travellers. Here's what to prepare.
Migraine in Costa Rica: what changes when you travel
Costa Rica's combination of high humidity, tropical heat, altitude variation between the Central Valley and coastal lowlands, and irregular sleep schedules from long travel days creates a concentrated set of triggers. Triptans are available in pharmacies in San José but supply is inconsistent outside major urban centres. CGRP monoclonal antibodies such as erenumab are not registered with Costa Rica's Caja Costarricense de Seguro Social (CCSS) formulary and require you to bring your full supply.[6][2]
This guide covers medication import rules, local brand names, cold-chain requirements for injectable preventives, how to find a neurologist in San José, and what to say in Spanish in an emergency.
Medical disclaimer: This guide is for informational purposes only and does not constitute medical advice. Always consult your specialist before travelling, particularly regarding changes to your treatment schedule and travel insurance.
Key risks for migraine travellers in Costa Rica
Tropical heat and humidity
Coastal lowlands regularly reach 32-35°C (~90-95°F) with humidity above 80%, conditions that accelerate dehydration and vasodilatation. Carry oral rehydration salts and schedule outdoor activity before 10 am or after 4 pm.[6]
Altitude changes between regions
San José sits at approximately 1,170 m above sea level, while Pacific and Caribbean coasts are at or near sea level. Rapid moves between these elevations can precipitate attacks; plan one rest day when travelling between highland and coastal destinations.[6]
Inconsistent triptan supply outside San José
Sumatriptan is stocked by Farmacia Fischel and Farmacia La Bomba chains in San José, but availability in rural areas and beach towns is unreliable. Bring more than you calculate you need for the duration of your trip.[4]
CGRP biologics not locally available
Erenumab (Aimovig), fremanezumab (Ajovy), and galcanezumab (Emgality) are not registered by Costa Rica's Ministerio de Salud for routine dispensing. Bring your entire supply, including a buffer for trip delays.
Water safety variation by region
Tap water safety varies by region in Costa Rica; untreated water or foodborne illness can precipitate attacks through dehydration and disrupted sleep[7]. Use sealed bottled water in rural areas and remote beach destinations.
Preparation checklist
- Get a neurologist letter in Spanish — Your letter should state your diagnosis (migraña crónica), current medications by INN, and that you carry acute and preventive treatments for personal use.
- Obtain prescriptions with INN names — Costa Rican pharmacists recognise INN names; brand-only prescriptions create delays at the pharmacy counter.
- Check cold-chain requirements for your preventive — If you take an injectable CGRP inhibitor, confirm storage arrangements with your hotel or Airbnb host before arrival.
- Check water safety for each region on your itinerary — Use bottled or filtered water in rural areas and on both coasts to reduce gastrointestinal risk.
- Download offline maps of San José pharmacies — Farmacia Fischel and Farmacia La Bomba have multiple San José branches open extended hours; save addresses offline.
- Create or update your Nomedic IPS — Your International Patient Summary holds your diagnosis, medications, allergies, and emergency contacts in a format any clinician can read.
- Confirm medication supply — Bring at least 30% more than your calculated trip requirement; rural pharmacies may not stock your brand.
- Pack oral rehydration salts — Available locally but easier to bring from home; dehydration is one of the fastest-acting triggers in tropical climates.
- Save emergency numbers — 911 covers ambulance, police, and fire in Costa Rica; save this alongside your insurer's 24-hour line in Nomedic.
- Research neurologists near your itinerary — Hospital ClÃnica BÃblica and Hospital CIMA in San José both have neurology departments with English-speaking consultants.
Documents to carry when travelling to Costa Rica with migraine
Keep all documents accessible on your phone via the Nomedic app; Costa Rican clinicians can read your IPS without needing to be familiar with your home country's record formats.
Your International Patient Summary (IPS)
Your Nomedic IPS holds your migraine diagnosis, current preventive and acute medications (by INN and brand name), allergies, and treating neurologist's contact details in a standardised format readable by any clinician worldwide.
In Costa Rica, where emergency department staff may have limited familiarity with CGRP inhibitors or less common preventive regimens, showing your IPS immediately reduces the risk of duplicate treatment or contraindicated prescribing.
Full document checklist
Keep the following accessible on your phone and ready to share. Your Nomedic IPS covers items 1 and 6 automatically.
- ·Your Nomedic IPS Covers your migraine diagnosis, medications, allergies, and functional status. Offline and QR-shareable.
- ·Neurologist letter in Spanish Must state your diagnosis (migraña crónica), all medications by INN, and confirm the supply you carry is for personal use.[1]
- ·Prescriptions with INN names Costa Rican pharmacists work from INNs; include both the INN and your home-country brand name on every prescription.[1]
- ·Travel insurance schedule Policy number and insurer's 24-hour line saved in your Nomedic profile.
- ·Cold-chain documentation for injectables If you carry a CGRP inhibitor, include the product SmPC storage section in your document folder.[5]
- ·Emergency numbers Ambulance, police, and fire all reach 911 in Costa Rica. Saved offline in Nomedic.[2]
Bringing your migraine medications to Costa Rica
Costa Rica's Ministerio de Salud permits personal medication imports for documented medical use when accompanied by a valid prescription or doctor's letter. Triptans and standard preventives such as propranolol and topiramate are not controlled substances and do not require import permits. CGRP monoclonal antibodies require a doctor's letter in Spanish confirming personal use, as they are not registered on the CCSS formulary.[1]
Do not post your medication to Costa Rica.
Postal import of prescription medications into Costa Rica is prohibited under the Reglamento de Estupefacientes, Psicotrópicos y otras sustancias fiscalizadas. Always carry your full supply in hand luggage on the aircraft.
Migraine medications: brand names, INNs, and Costa Rica availability
The table below lists common migraine medications with the brand names most likely encountered at Costa Rican pharmacies and any travel-relevant storage notes.
Available at major San José pharmacies; stock in rural areas is unreliable. Bring your full supply.
Limited availability outside San José. Bring full supply.
Do not stop abruptly; abrupt discontinuation carries cardiac risk.
Not registered in Costa Rica. Bring your entire supply. Requires refrigeration at 2-8°C.
Ergotamine and triptans: do not combine
Ergotamine-containing preparations are available in some Costa Rican pharmacies and may be offered as an alternative if your triptan is out of stock. Ergotamine and triptans must not be used within 24 hours of each other due to additive vasospastic risk, as documented in the sumatriptan prescribing information. Inform any pharmacist or clinician of your current triptan use before accepting any alternative.
Travelling with injectable preventives
If your preventive is an injectable CGRP inhibitor, these steps apply regardless of which region of Costa Rica you are visiting. For detailed advice on maintaining the cold chain, see our CGRP biologics travel guide.
Your medication list, ready to share.
Nomedic stores your medication name, INN, dosage, and frequency, readable by any clinician worldwide.
Healthcare and prescriptions in Costa Rica
Costa Rica's public health system, the Caja Costarricense de Seguro Social (CCSS), covers residents and contributors but does not extend to most international travellers on short-stay visits. Emergency stabilisation at a CCSS hospital is available to anyone, but follow-up neurology care requires either CCSS enrolment or private payment.
Private neurology consultations in San José cost approximately ₡35,000-₡70,000 (~$77-$154 / ~€71-€142). Foreign prescriptions are not dispensed directly at Costa Rican pharmacies; a local doctor's prescription is required for any in-country purchase requiring a prescription.[3][2]
Sumatriptan and rizatriptan are prescription-only (Rx) in Costa Rica; a local doctor's consultation is required to obtain them locally if your supply runs out. Topiramate and propranolol are also prescription-only but more widely stocked. Bring your full supply of all medications and plan for no in-country refill of CGRP biologics.
CGRP biologics are dispensed differently
Erenumab, fremanezumab, and galcanezumab are not available through Costa Rican retail pharmacies or the CCSS formulary. If your supply is damaged or lost, contact your travel insurer's emergency assistance line; medical evacuation or international courier arrangements may be the only options. Bring your IPS and specialist letter to any clinical consultation.
Finding a migraine specialist
Neurologists (neurólogos) practise within the neurology departments of private hospitals in San José, principally Hospital ClÃnica BÃblica (Avenida 14, Calle Central) and Hospital CIMA (Escazú). Both hospitals have English-speaking consultants and accept walk-in urgent appointments, though same-day neurology slots are not guaranteed. Identify the hospital closest to your itinerary before travel and save the address and phone number offline in Nomedic.
Search for providers near your destination
Use Nomedic's provider search to find migraine specialists in Costa Rica. Save the address and phone number offline before you travel.
If you run out of medication or your supply is lost in Costa Rica
Running short of triptans in San José is recoverable; running short of a CGRP biologic anywhere in Costa Rica requires insurer involvement. Act quickly and stay calm; the steps below apply to both situations.
Managing heat, altitude, and daily triggers in Costa Rica
Coastal lowlands in Costa Rica regularly reach 32-35°C with relative humidity above 80%, conditions that compound dehydration faster than many travellers anticipate. San José at 1,170 m is cooler and drier, but rapid altitude changes between highland and coast within a single day are a known trigger.[6]
Schedule demanding outdoor activity before 10 am or after 4 pm on coastal days. Drink at least 2 litres of water daily and supplement with oral rehydration salts on high-exertion days. Sealed bottled water is advisable in rural areas.
Bright equatorial sunlight is intense even in overcast conditions; UV-blocking sunglasses reduce photic trigger exposure on beach and rainforest excursions. If you move between the Central Valley and the coast, plan a rest afternoon on arrival rather than continuing with sightseeing immediately.
Distinguishing a heat-triggered attack from heat illness
A migraine triggered by heat typically resolves within your usual attack window once you move to a cool, dark environment and take your acute medication. If you develop confusion, core temperature above 39°C, or are unable to take fluids after two hours in a cool environment, these suggest heat illness rather than migraine. Follow the guidance in the Emergency tab if these symptoms appear.
Spanish phrases for clinicians
Show your Nomedic IPS first, it removes the need to explain your diagnosis verbally. If verbal communication is needed:
“Tengo migraña crónica.”
I have chronic migraine.
“Estoy teniendo un ataque de migraña.”
I am having a migraine attack.
“Necesito ver a un neurólogo.”
I need to see a neurologist.
“Tomo sumatriptán para la migraña.”
I take sumatriptan for migraine.
“¿Dónde está el hospital privado más cercano?”
Where is the nearest private hospital?
“Necesito un suministro urgente de mi medicamento.”
I need an emergency supply of my medication.
Insurance considerations
What to know about travel insurance
Many standard travel insurance policies list chronic migraine under pre-existing condition exclusions, meaning acute attack treatment, emergency neurology consultations, and medication replacement will not be covered unless you have declared the condition and paid for a waiver. A private neurology consultation in San José costs approximately ₡35,000-₡70,000 (~$77-$154 / ~€71-€142), and emergency department attendance at a private hospital can exceed ₡500,000 (~$1,100 / ~€1,020).
What to look for in a policy
Not just 'pre-existing conditions covered'. Your condition should be named on the schedule.
Covers repatriation to your home country if local care is insufficient.
Covers emergency replacement if your medication is lost, damaged, or delayed.
So someone can communicate with Costa Rican clinicians on your behalf.
What to declare at application
Declare thoroughly. Incomplete disclosure can invalidate your entire policy, not just the migraine-related claim.
State whether your migraine is chronic (15 or more headache days per month) and whether it includes aura.
Use the INN alongside the brand name.
Insurers use recent severity as a proxy for trip risk.
Declare depression, anxiety, hypertension, or other comorbidities that share medications with your migraine treatment.
Your policy number and emergency assistance line, saved alongside your IPS and accessible offline.
Costa Rica has no reciprocal public healthcare agreement with EU or EEA countries, so an EHIC or GHIC card provides no coverage here. EU and EEA travellers should treat Costa Rica as a fully private-pay destination and ensure their policy covers specialist neurology consultations, acute migraine treatment, and emergency medication replacement.
Emergency protocol
Attending a hospital emergency department
Status migrainosus (an attack lasting more than 72 hours) and migraine with prolonged neurological symptoms require emergency evaluation to exclude secondary causes. Contact your travel insurer's emergency assistance line before attending a private hospital to activate direct billing where available.
When you arrive, follow in order
Full clinical picture in seconds, no verbal explanation needed.
Hand your phone to the triage nurse:
Tengo migraña crónica y llevo más de 72 horas con el ataque.
I have chronic migraine and my attack has lasted more than 72 hours.
This confirms your current preventive regimen and reduces the risk of contraindicated treatment.
Tell the attending clinician which acute medications you have already taken and the time of the last dose before any additional treatment is given.
Calls and location
Call 911 for ambulance, police, and fire anywhere in Costa Rica. If you are in a remote area, ask your accommodation to contact the nearest Cruz Roja (Red Cross) station, which operates ambulance services nationally.
In hospital
Some pain management protocols used in Costa Rican emergency departments include opioids or NSAIDs that interact with migraine preventives, particularly those with serotonergic or cardiovascular effects. Show your full medication list from your Nomedic IPS to every clinician who attends you.
After any emergency
Before you leave the hospital if possible.
Required for insurer reimbursement and continuity of care.

Frequently asked questions
Is it legal to bring migraine medications, including triptans and erenumab (Aimovig), into Costa Rica?
Yes, it is legal to bring personal-use quantities of migraine medications into Costa Rica, provided you carry a valid prescription or doctor's letter confirming the diagnosis and personal use. This applies to triptans such as sumatriptan and rizatriptan as well as CGRP biologics such as erenumab (Aimovig). Triptans are not classified as controlled substances under Costa Rican law and do not require an import permit.
Erenumab is not registered on the CCSS formulary, so a Spanish-language doctor's letter is especially important. It demonstrates that the biologic is for your personal treatment and not for distribution. Carry all documentation together with your medication in hand luggage. Postal import of any prescription medication is prohibited; everything must travel with you on the aircraft.
What to carry
Original manufacturer packaging, a signed doctor's letter in Spanish (including INN, brand name, dosage, and frequency), and your Nomedic IPS document. Present these proactively at customs if asked.
Is sumatriptan available over the counter in Costa Rica?
No. Sumatriptan is prescription-only in Costa Rica; you need a locally issued prescription to purchase it at a pharmacy. Bring your full supply from home and a doctor's letter in Spanish in case you need to obtain a local prescription.
Can I bring erenumab (Aimovig) into Costa Rica?
Yes, you can carry erenumab (Aimovig) for personal use accompanied by a doctor's letter confirming the diagnosis and personal use. Erenumab is not registered in Costa Rica and cannot be obtained locally, so bring your entire trip supply plus a buffer for delays.
Do not post biologics to Costa Rica
Postal import of prescription biologics is prohibited. All medication must travel with you in hand luggage.
Are migraine medications available at Costa Rica pharmacies?
Sumatriptan and rizatriptan are available at major pharmacy chains in San José, such as Farmacia Fischel, with a local prescription. Supply outside San José, including beach resorts and rural areas, is inconsistent. CGRP biologics are not stocked at any Costa Rican retail pharmacy.
How do I communicate my migraine diagnosis in a Costa Rica emergency?
Show your Nomedic IPS first. If verbal communication is needed:
“Tengo migraña crónica.”
I have chronic migraine.
“Tomo sumatriptán y erenumab para la migraña.”
I take sumatriptan and erenumab for migraine.
Do I need special travel insurance to visit Costa Rica with chronic migraine?
Standard travel policies commonly exclude chronic migraine as a pre-existing condition, leaving acute attack treatment, neurology consultations, and replacement medication costs uncovered. A private neurology consultation in San José costs approximately ₡35,000-₡70,000 (~$77-$154 / ~€71-€142) and emergency department attendance at a private hospital can exceed ₡500,000 (~$1,100 / ~€1,020).
Declare thoroughly
Subtype, current medication, last severe episode, and associated conditions. Incomplete disclosure invalidates the entire policy, not just the migraine-related claim.
Does Costa Rica's tropical climate make migraines worse?
Coastal lowlands regularly exceed 32°C with humidity above 80%, which accelerates dehydration and can lower your attack threshold. The altitude shift between San José (1,170 m) and coastal areas near sea level in a single day adds a second trigger.
Hydration and timing
Drink at least 2 litres of water daily, use oral rehydration salts on high-exertion days, and schedule outdoor activity before 10 am or after 4 pm on coastal days to reduce heat exposure.
