For severe high altitude illness, which combination of medications is recommended?

• A. Acetazolamide and Dexamethasone
• B. Ibuprofen and Aspirin
• C. Doxycycline and Prednisone
• D. Albuterol and Beclomethasone

Answer: (A)

Severe high-altitude illness is driven by two main problems: the need to improve acclimatization and the risk of cerebral edema. Acetazolamide helps with acclimatization by causing a mild metabolic acidosis, which stimulates ventilation and improves oxygenation as you ascend. Dexamethasone directly counteracts cerebral edema and inflammation, reducing swelling and intracranial pressure to relieve severe symptoms like headache, confusion, or ataxia that indicate high-altitude cerebral edema. Together, they address both the ventilatory drive and potential brain swelling, which is why this combination is recommended. The other pairs don’t target these core issues: they include analgesics, antibiotics, or asthma meds that don’t treat cerebral edema or acclimatization in severe altitude illness. Descent and supplemental oxygen remain essential parts of management.
