Travel medicine for the Ethiopian highlands
In Ethiopia the altitude starts on day one. Lalibela sits at 2,500 meters before you ever reach the Simien trailhead.
Get the altitude medication the CDC recommends for travel above 2,500 meters, prescribed without the appointment. Sent to your pharmacy, ready before you fly to Addis Ababa.

The Northern Historic Circuit is high from the moment you land. Addis Ababa is 2,355 meters, Lalibela and its rock-hewn churches sit right at 2,500 meters, and the Simien Mountains trek climbs from there to overnight camps at Geech and Chenek around 3,600 meters before the Bwahit Pass at 4,200 meters and the Ras Dashen approach at 4,543 meters. That is a sustained stay in the altitude band where the CDC says acute mountain sickness becomes common, and the upper camps sit in its high-risk category. Acetazolamide compresses the body's normal three to five day acclimatization into one. Started the day before you fly in, it is the difference between walking the escarpment clearheaded and spending your acclimatization days flattened by a headache.

Ethiopia medication FAQ
- The Ethiopian Northern Circuit is high from the start. Lalibela sits at about 2,500 meters, Addis Ababa at 2,355 meters, and the Simien Mountains trek overnights at Geech and Chenek camps around 3,600 meters before the Bwahit Pass at 4,200 meters and Ras Dashen at 4,543 meters. The CDC sets the threshold for acute mountain sickness at sleeping altitudes above 2,500 meters and places sleeping above 3,400 meters in its high-risk band, so the Simien camps put almost every trekker squarely in the zone where AMS is common. The CDC recommends acetazolamide chemoprophylaxis for ascents in this range, and Wilderness Medical Society guidelines reinforce it. Started the day before you fly in, Diamox compresses the body's normal three to five day acclimatization into one.
- The CDC recommends 125 mg twice daily, starting one day before ascent, continuing through ascent and for at least two days at your highest altitude. Because Ethiopia is high the moment you land, that usually means starting the morning before your flight into Addis Ababa, continuing through your days in Lalibela, and keeping it going across the Simien camps and over the Bwahit Pass. Side effects most travelers notice are tingling in fingers and toes, more frequent urination, and a flat taste to carbonated drinks. Your provider will walk through the timing during your visit.
- Three medications that cover the altitude exposure across the Northern Historic Circuit and the multi-day Simien trek. Acetazolamide (Diamox) is the AMS prophylaxis the CDC recommends for travel above 2,500 meters, taken 125 mg twice daily starting the day before you fly in. Prescription-strength ibuprofen handles the altitude headache on the Lalibela acclimatization days and the soreness of the long escarpment hikes, which the CDC notes ibuprofen 600 mg every 8 hours independently helps prevent. Hydroxyzine (Vistaril) addresses the broken sleep that becomes nearly universal above 2,700 meters and that the CDC explicitly flags as an AMS amplifier through periodic breathing, and it doubles for jet lag on the long-haul arrival into Addis. Together they cover the symptoms that wear travelers down across the highland circuit.
- Not on the highland circuit. The CDC reports malaria in Ethiopia in areas below 2,500 meters, and risk falls away across the highlands, with little to none in Addis Ababa, Lalibela, Gondar, and the Simien Mountains. The Northern Circuit sits at and above that line, so the dominant health story here is altitude, not malaria. If your trip also dips into the lowlands, such as the Omo Valley, the Awash area, or the Lower Rift, that is a separate malaria conversation, and your provider can cover it during your visit.
- Orders are reviewed by a US-licensed provider and the Rx is sent electronically to your pharmacy within 24 hours. Most travelers can pick it up the same day.
- If a provider cannot safely prescribe (rare, usually due to a sulfa allergy with prior anaphylaxis or a kidney contraindication for acetazolamide), the visit fee is refunded in full. You only pay if the Rx is sent.
Lalibela is 2,500 meters and the Simien camps climb higher still. Start the medication that keeps the altitude from defining your trip.
