Leh sits at 3,500 meters in the Indian Himalaya, and most travelers arrive on the 90-minute flight from sea-level Delhi. The CDC classifies any rapid air ascent above 3,400 meters as the highest-risk scenario for acute mountain sickness, with rates approaching 50 percent of travelers when staged acclimatization is skipped. Day trips to Khardung La at 5,359 meters and overnights at Pangong Lake at 4,350 meters push the exposure higher. Acetazolamide compresses the body's normal three to five day acclimatization into one. Started the day before you board the Delhi flight, it is the difference between exploring the monasteries of the Indus Valley and spending day two in your guesthouse.

Ladakh medication FAQ
- The CDC classifies any rapid ascent by airplane above 3,400 meters as the highest-risk scenario for acute mountain sickness, with rates approaching 50 percent of travelers when staged acclimatization is not feasible. Leh sits at roughly 3,500 meters, and the standard route in is the 90-minute flight from Delhi at sea level. There is no overland acclimatization built into that itinerary, so day one in Leh is also day one above 3,000 meters for almost every traveler. The CDC recommends a low threshold for acetazolamide chemoprophylaxis in exactly this scenario, and Wilderness Medical Society guidelines reinforce it. Started the day before your flight, 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. For most Ladakh itineraries that means starting the morning before you board the Delhi to Leh flight, continuing through your two to three acclimatization days in the Indus Valley, and keeping it going as you climb toward Khardung La, Nubra Valley, or Pangong Lake. 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 a typical seven to ten day Ladakh itinerary. Acetazolamide (Diamox) is the AMS prophylaxis the CDC recommends for ascending above 2,500 meters, taken 125 mg twice daily starting the day before you fly to Leh. Prescription-strength ibuprofen handles the altitude headache that hits in the first 24 hours at 3,500 meters and that the CDC notes ibuprofen 600 mg every 8 hours independently helps prevent. Hydroxyzine (Vistaril) addresses the sleep disruption that becomes nearly universal above 2,700 meters and that the CDC explicitly flags as an AMS amplifier through periodic breathing. Together they cover the symptoms that keep people inside during their first days in Leh and on the climb up to Khardung La.
- 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.
- After your provider approves the Rx, it is sent electronically to whichever pharmacy you choose during your visit. Your pharmacy will tell you when the medication is ready for pickup. You can use your pharmacy insurance to cover the medication itself.
- 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.
