From the Guidelines
Coca leaf tea is not recommended for elevation due to lack of evidence supporting its effectiveness and potential legal and health concerns. When traveling to high altitude destinations, it is essential to consider the risks of high altitude retinopathy (HAR) and non-arteritic ischaemic optic neuropathy (NAION) 1. To prevent high altitude illness, including acute mountain sickness, proper acclimatization, gradual ascent, staying hydrated, and avoiding alcohol and smoking are crucial 1. Prophylactic medications, such as acetazolamide, can be effective in preventing altitude sickness, but individuals should be aware of potential side effects like a transient myopic shift and have proper corrective measures in place 1. Some key points to consider when traveling to high altitudes include:
- Proper acclimatization and gradual ascent to prevent altitude sickness
- Staying hydrated and avoiding alcohol and smoking
- Considering prophylactic medications like acetazolamide for individuals with a history of severe altitude sickness
- Being aware of the potential risks of HAR and NAION, and seeking medical attention if symptoms occur It is essential to prioritize evidence-based recommendations and consult with a healthcare professional before traveling to high altitude destinations, rather than relying on unproven remedies like coca leaf tea.

From the Research
Elevation and Altitude Sickness
- Altitude sickness can occur at heights over 2,500 m due to the decreasing partial pressure of oxygen 2
- The most common form of high altitude sickness is acute mountain sickness, characterized by headache, and can be avoided by slow adaptation to the altitude (acclimatization) 2
- Acetazolamide is a commonly used medication for the prevention and treatment of acute mountain sickness (AMS) 3, 4, 5, 2, 6
Treatment and Prevention of Altitude Sickness
- Acetazolamide can be administered to prevent and treat AMS, with doses of 500-750 mg/day appearing to be the most effective for minimizing symptoms of AMS during rapid ascents to altitudes >3,500 m 5
- Dexamethasone can be used to treat high altitude cerebral edema, and nifedipine can be used to treat high altitude pulmonary edema 4, 2, 6
- Rapid descent to a height of at least 500 m is recommended for all forms of high altitude sickness 2
