Altitude medicine and first aid supplies in Kathmandu pharmacies

A Kathmandu pharmacy is a good place to top up plasters, tape, oral rehydration salts, simple pain relief and sunscreen, but not to start altitude medicine. The CDC lists acetazolamide, dexamethasone and nifedipine as drugs for specific altitude problems and tells people with health conditions to see a physician who knows high-altitude medicine first. We found no official statement on whether acetazolamide needs a prescription in Nepal, so we do not claim either. Medicine quality is uneven: a Kathmandu Valley study found 32.5 percent of 40 sampled medicines substandard, and the Department of Drug Administration seized counterfeit asthma inhalers in June 2026. Buy sealed packs from an established pharmacy, keep receipts, and bring prescription items from home. This is general information, not medical advice. See a doctor or travel clinic before you buy any altitude drug. Sources checked 25 October 2026.

What is a Kathmandu pharmacy good for?

Think of it as a top-up shop. By the time you reach Kathmandu you should already hold the medicines you rely on, because a pharmacy cannot replace a doctor who knows your history. Our first aid kit guide lists what a kit contains, and the pharmacy is where you fill gaps in the bulky, low-risk items: plasters and blister dressings, medical tape, antiseptic wipes, oral rehydration salts, simple pain relief, sunscreen and lip balm. If you also need a water treatment method, shops in tourist areas usually stock tablets, though we have no source ranking them.

Check each pack before you leave the counter. The 2026 Kathmandu Post report on counterfeit inhalers says inspectors spotted the fakes partly through typographical errors in the printed packaging literature. That is a news detail, not a test you can rely on, but it is a sensible habit to read the box, check the expiry date and batch number, and refuse a pack that has been opened or relabelled.

Which altitude drugs exist, and why see a doctor first?

The CDC Yellow Book describes the main drugs. Acetazolamide is the one used to prevent acute mountain sickness (AMS) and is described as approved in the United States for that use. Ibuprofen can also help prevent AMS, though the CDC says not quite as effectively. Dexamethasone treats AMS and the more serious high-altitude cerebral oedema, but the CDC says it is generally reserved for treatment as an adjunct to descent. Nifedipine is for high-altitude pulmonary oedema and is generally reserved for people who are particularly susceptible.

The same page says travellers with underlying conditions, including heart disease, chronic lung disease or sleep apnoea, should consult a physician familiar with high-altitude medical issues before travel. It also says chronic conditions should be stable before departure. That advice points to a doctor visit at home, weeks before you fly. We do not give doses here. Our Diamox guide sets out what the CDC says and what to ask your doctor, and the altitude sickness basics cover symptoms.

A drug does not replace a slow ascent. A Nepali Times article by Dr Buddha Basnyat, dated 26 September 2014, says the Himalayan Rescue Association strongly recommends a gradual ascent without drugs, and that the best prevention is an itinerary with gradual acclimatisation. It also notes that some travellers, such as those landing quickly at a high airport, cannot ascend slowly. Read the acclimatisation schedule and the 300 metre sleeping rule before you buy anything.

Can you buy prescription drugs without a prescription?

We could not confirm the current rule. We found no official Nepali statement on whether acetazolamide, dexamethasone or antibiotics need a prescription at the counter. A 2004 Nepali Times investigation reported that antibiotics were easy to buy without a prescription and that doctors said prescription rules were poorly enforced. That article is more than twenty years old, and we do not know today's enforcement.

Even if a pharmacist will sell a drug, that is not the same as it being right for you. Allergies, pregnancy, kidney problems and other medicines all matter. The CDC notes, for example, that acetazolamide needs caution with a history of anaphylaxis to any medication or multiple drug allergies. If you want altitude medicine, get it from your own doctor, test it at home, and carry the original packaging and a note naming the drug.

How careful should you be about counterfeit medicines?

Careful, without panic. A study published by the Nepal Health Research Council journal for 2015 tested 40 samples, five brands each of eight medicines, in Kathmandu Valley and found 32.5 percent substandard: 40 percent of domestic brands and 28 percent of imported brands. It is a small, old sample, and its authors asked for larger testing, so treat the figure as a warning rather than a rate.

The newer evidence is the June 2026 Kathmandu Post report. The Department of Drug Administration seized suspected counterfeit Seroflo Rotacaps 250, an asthma inhaler, from wholesalers in Kathmandu and several other districts. The acting director general said the department did not know whether the fakes contained active ingredients, and the report says about two dozen inspectors oversee roughly 25,000 pharmacies. Our practical reading: for anything you cannot afford to have fail, such as an inhaler, insulin or an epinephrine pen, bring it from home in its original pack. For a packet of plasters, the risk is low.

Simple precautions

• Buy sealed boxes from an established, licensed-looking pharmacy, not a street stall or a trekking shop that sells medicine on the side.
• Keep the box, the leaflet and the receipt, and note the batch number.
• Do not accept loose tablets without packaging.
• Do not combine a new drug with your regular medicines without asking a doctor or pharmacist.

Where can you get proper advice in Kathmandu?

Two names come up in our sources. The Himalayan Rescue Association lists a Kathmandu office at Dhobichaur, Lazimpat, with phone numbers on its site, and runs aid posts at Pheriche and Manang; its site says the Pheriche post is manned during the trekking season by volunteer doctors. Our guide to the HRA clinics at Manang and Pheriche explains what they offer. CIWEC is described as a travel medicine clinic in Kathmandu, founded in 1982 according to Wikipedia, which is flagged as lacking citations, so check the clinic's own site for hours and services. A GeoSentinel analysis of CIWEC records cited in search results found altitude illness in 9 percent of diagnoses, but we could not open that paper, so we do not rely on it.

We could not confirm walk-in hours for either. Call first, and never wait until you are sick on the trail to find out what you needed.

What should you do if you feel unwell on the trail?

If symptoms are mild, rest and do not go higher, which is the usual rule in our altitude sickness basics. If they are getting worse, the answer is descent and help, not a new tablet. Tell your guide, lodge owner or partner early, because the people around you notice confusion and poor balance before you do.

Do not self-treat a worsening headache with a pharmacy purchase from Kathmandu. Our HAPE and HACE warning signs guide explains when descent is the answer. Save the numbers in the emergency numbers guide, carry a pulse oximeter only if you understand its limits, and read travel insurance for high altitude trekking before you fly. Where the plan includes the Everest Base Camp route or the Annapurna Circuit, the HRA posts are on the way, but they are not open all year.

Where sources conflict or are silent

• Prescription rules: we found no official source on whether acetazolamide, dexamethasone or antibiotics need a prescription in Nepal. The only evidence is a 2004 article saying rules were poorly enforced.
• Drug use: the HRA position quoted by Nepali Times (2014) favours slow ascent without drugs, while the CDC lists acetazolamide as an option for medium and high risk travellers. Both can be true; the choice is for you and a doctor.
• Counterfeit rates: 32.5 percent substandard in a 2015 sample of 40, against a 2004 official quote that the problem was minimal. Neither is a current national figure.
• CIWEC and HRA opening hours were not confirmed. The CIWEC founding year comes from Wikipedia with a citation flag.
• We found no source on which Kathmandu pharmacies are reliable. We do not name any.

Sort the medical plan, then find a partner

A partner who knows your plan and your medicines is a safety net. Share what you take, and agree a descent rule before you start, using our partner safety roles and emergency plan. Then browse trips, post a trip or read the trekking partner page. We are a matching platform, not a clinic or a pharmacy, and this page is not medical advice.
