How to Handle Altitude Sickness in Cusco
Arrive in Cusco 2-3 days before any strenuous activities and stay hydrated. Take acetazolamide (Diamox) starting 24 hours before arrival if you're prone to altitude sickness. Rest on your first day and avoid alcohol.
- Start prevention before you arrive. Take acetazolamide (Diamox) 125-250mg twice daily starting 24-48 hours before arrival. Consult your doctor first. Avoid alcohol and sleeping pills for 48 hours before travel.
- Plan a gradual ascent if possible. Fly into Lima first, then take a connecting flight to Cusco. If driving, stop overnight in Arequipa (7,660 feet) before continuing to Cusco (11,200 feet).
- Take it easy on arrival day. Check into your hotel and rest. Avoid heavy meals, alcohol, and any physical exertion. Drink 3-4 liters of water throughout the day.
- Recognize the symptoms early. Watch for headache, nausea, fatigue, dizziness, or trouble sleeping within 6-24 hours of arrival. These are normal mild symptoms that usually resolve in 1-3 days.
- Treat mild symptoms immediately. Take ibuprofen or acetaminophen for headaches. Drink coca tea (mate de coca) available everywhere in Cusco. Rest and stay hydrated.
- Know when to seek medical help. Get immediate medical attention for severe headache, vomiting, confusion, difficulty breathing, or loss of coordination. These indicate serious altitude sickness requiring treatment.
- Acclimatize properly before Machu Picchu. Spend at least 2 full days in Cusco before hiking or visiting Machu Picchu. Schedule easier activities like city tours on days 1-2, save strenuous activities for day 3+.
- How long does altitude sickness last in Cusco?
- Mild symptoms typically resolve within 1-3 days as your body acclimatizes. Most people feel significantly better by day 2 or 3.
- Can I take Diamox without a prescription?
- No, acetazolamide requires a prescription in most countries. Consult your doctor 2-3 weeks before travel to get it prescribed.
- Is coca tea actually effective?
