What is Altitude Sickness and How Acetazolamide Helps

Altitude sickness occurs when your body struggles to adjust to lower oxygen levels at high elevations. Symptoms may include headache, nausea, dizziness, and fatigue. Acetazolamide is a medication that can help your body adjust by balancing chemicals in your blood, reducing symptoms and helping prevent altitude sickness when taken before and during high-altitude travel.

Preparing for Your Video Visit

Before your appointment, gather information about your health history, including any allergies, medications, and past reactions to altitude or medications. Have details about your travel plans ready, such as your destination's altitude and how quickly you will ascend. Make sure you have a quiet, private space with good internet connection for the video call.

What to Expect During the Video Visit

Your healthcare provider will ask about your medical history, current health, and travel itinerary. They may discuss the benefits and possible side effects of acetazolamide, how to take it, and precautions to consider. You can ask questions about managing altitude sickness symptoms and when to seek emergency care.

Safety and Side Effects of Acetazolamide

Common side effects may include frequent urination, tingling in the fingers or toes, and taste changes. Serious side effects are rare but require immediate attention. Your provider will explain how to recognize side effects and what to do if they occur.

When to Seek In-Person Care

If you experience severe headache, difficulty breathing, confusion, or loss of coordination at high altitude, seek emergency medical care immediately. These may be signs of serious altitude sickness requiring prompt treatment beyond telemedicine support.
