Who Is This Service For?

  • Trekkers heading to Everest Base Camp (5,364m), Annapurna Circuit (5,416m), Manaslu, Langtang, or Gokyo wanting a personalized ascent & medication plan
  • Travelers with pre-existing asthma, hypertension, diabetes, or prior AMS seeking a safe high-altitude clearance
  • Trekkers who descended early or via helicopter evacuation needing lung/neuro evaluation, chest imaging referral, and insurance claim validation
  • Climbers suffering from persistent high-altitude cough ("Khumbu cough"), headache, or fatigue after returning to Kathmandu

What Happens During Your Appointment?

1. Resting and post-exertion pulse oximetry (SpO2), blood pressure, lung auscultation (checking for HAPE rales), and neurological ataxia screening.

2. For pre-trek visits: Day-by-day elevation profile review of your itinerary (identifying sleeping-altitude jumps >500m above 3,000m).

3. Sulfa-allergy screening and dispensing of prophylactic or therapeutic medications (Acetazolamide 125mg/250mg, Dexamethasone, Nifedipine) with laminated pocket dosing cards.

4. For symptomatic post-trek patients: Supplemental high-flow oxygen therapy on-site, chest X-ray coordination if pulmonary edema is suspected, and recovery monitoring.

5. Comprehensive high-altitude medical report for helicopter rescue insurers and trek operators.

⚠️ When to Seek Immediate Emergency / Hospital Care

  • Breathlessness at rest, gurgling/rattling chest sounds, blue lips, or coughing up pink frothy sputum (suspected HAPE — medical emergency)
  • Confusion, severe lethargy, inability to walk heel-to-toe in a straight line (ataxia), or irrational behavior (suspected HACE — medical emergency)
  • If you are currently on the trail above 2,500m with these signs: STOP ascending, DESCEND immediately (≥500–1,000m), administer oxygen/dexamethasone, and arrange urgent evacuation

Before You Book — What to Have Ready

  • Your passport — required for the medical report and any insurance documentation; a photo on your phone works for registration.
  • Your insurance details — policy number and the insurer's 24/7 assistance line; if a GOP (guarantee of payment) is needed, it is arranged before or during the visit, not after.
  • Your medication list — names, doses, and frequency of anything you take regularly, plus known allergies. Interactions are checked before anything is prescribed or administered.
  • A rough timeline — when the problem started, what changed, and what you have already tried. A messy timeline told honestly beats a tidy one that skips the embarrassing parts.
  • Your departure date — if you are flying, trekking, or leaving Kathmandu soon, say so at booking; it changes what gets prioritized and what gets deferred.

What This Service Does Not Include

  • Hospital-level care — ICU, surgery, advanced imaging beyond our on-site capability, and overnight admission are referred to Kathmandu partner hospitals with your records transferred.
  • Open-ended monitoring — if a condition needs serial checks over weeks, we set the follow-up schedule explicitly rather than leaving it vague.
  • Guaranteed outcomes — we commit to the assessment, the honest answer, and the documented plan; no ethical clinic guarantees a result.
  • After-hours emergency response — outside opening hours, Kathmandu emergency departments handle overnight crises; our WhatsApp line is checked at opening.

After Your Appointment — Records, Refills & Follow-Up

  • You leave with documents. A stamped English ICD-10 medical report, itemized receipt, and any prescription with generic drug names — formatted for international insurers and home-country doctors.
  • WhatsApp follow-up is included. A 7-day check-in window — if a symptom changes, worsens, or a question comes up, message +977-9747726036 rather than booking a second consult for something we can answer remotely.
  • Refills and repeats. If a treatment course extends past your stay, we document the regimen in the report so a pharmacy or physician at your next destination can continue it — including the generic names that work across borders.
  • Referral letters. If the visit revealed something that needs a specialist or a hospital, the referral letter and your records go with you — the receiving doctor reads our findings rather than starting from zero.

Cost Transparency — What the Fee Covers

The fee range for Altitude Sickness (AMS) is $40 – $85 USD (NPR 5,400 – 11,400), confirmed upfront before any test or procedure begins. That price covers the consultation itself, the documentation, and the follow-up window — laboratory tests, medications, and consumables are itemized separately so you see exactly what you are paying for. There are no surprise line items on a Thamel Clinic receipt.

Payment, Insurance & the Real Total Cost

Most Altitude Sickness (AMS) visits stay inside the quoted $40 – $85 USD range; what pushes a bill higher is add-on diagnostics or a treatment course — never hidden fees. Payment is cash, Visa/Mastercard/Amex, eSewa, or Fonepay, and insured travelers with pre-authorized coverage can often use direct insurer billing (GOP) instead of paying out-of-pocket.

Value context: the same Altitude Sickness (AMS) visit in a Western urgent-care system typically runs 3–8× the Kathmandu price, and every visit ends with the stamped ICD-10 report insurers require — documentation most international clinics charge extra for.

Currency & cash flow: the bill is issued in NPR with the USD equivalent printed on the receipt, so a reimbursement claim never argues the exchange rate. If paying out-of-pocket, card settlement lands at your bank's rate (~NPR 133 per USD); if using GOP, the guarantee covers the approved line items and any non-covered extras are quoted before they are added — the bill is never padded while you wait.

Frequently Asked Questions: Altitude Sickness (AMS)

Can I get altitude sickness in Kathmandu itself?

No. Kathmandu sits at 1,400 meters (4,600 feet), where barometric pressure is sufficient to prevent Acute Mountain Sickness. However, Kathmandu is the ideal place to do your pre-trek medical checkup and obtain genuine Diamox before flying to Lukla (2,860m) or driving toward Manang.

What is the standard preventative dose of Diamox (acetazolamide)?

In accordance with Wilderness Medical Society (WMS) guidelines, the standard prophylactic dose is 125 mg taken twice daily (every 12 hours), starting 24 hours before ascending above 2,800m. Our physicians screen for sulfa allergies and kidney/liver contraindications before prescribing.

Do you validate medical necessity after a helicopter evacuation from the mountains?

Yes. Travel insurers require an objective post-evacuation clinical exam (recording SpO2, lung findings, Lake Louise score, and diagnosis) upon arrival in Kathmandu. We provide complete, transparent clinical reports accepted by major international assistance companies.
