Can an online doctor prescribe altitude sickness medication?

Yes. Acetazolamide - the standard altitude sickness prevention medication - is not a controlled substance, and prescribing it before a mountain trip is routine telehealth business. A travel-savvy online clinician reviews your itinerary, your health history, and any past altitude problems, then sends the prescription to your pharmacy so you have it before you leave. Who actually benefits: the CDC suggests considering acetazolamide when an abrupt ascent is unavoidable - flying directly to a high-altitude city, or a trek that gains elevation faster than the recommended pace of about 1,600 feet of sleeping altitude per day above 9,000 feet. If your itinerary allows a gradual ascent with two to three nights acclimatizing around 8,000 to 9,000 feet, slow climbing alone is markedly protective and many people skip the medication. Two honest caveats. Medication speeds acclimatization; it does not replace it - you still follow the ascent rules, avoid alcohol the first 48 hours, and take symptoms seriously. And acetazolamide is not for everyone: it is a sulfa-related diuretic, so sulfa allergy history, kidney issues, and pregnancy all factor into the decision, which is exactly what the consultation is for. Common side effects are tingling in the fingers and a funny taste for carbonated drinks - annoying, harmless, and worth knowing about before they surprise you on the trail.
