Mount Kilimanjaro’s summit is approximately 19,341 feet above sea level. That's quite a climb, and while not everyone reaches the top, the main reason for Kilimanjaro's 40% summit success rate is often attributed to high altitude. Many hikers seeking a better chance at reaching Uhuru Peak, the highest point, inquire about Diamox with their doctors. This prescription medication might help prevent or reduce the impact of high altitude on your body.
But what is Diamox? Is it really helpful, and can you conquer the summit without it? We're going to cover everything about Diamox and its use during a Mount Kilimanjaro climb, from its purpose to potential side effects and usage tips.
Understanding Diamox:
To begin, Diamox is the prescription name for the generic medication acetazolamide. While acetazolamide is prescribed for conditions like glaucoma, sleep apnea, epilepsy, and hypertension, it's also used to prevent altitude sickness.
Altitude sickness, or acute mountain sickness (AMS), occurs when your body ascends rapidly to high altitudes (usually above 10,000 feet or 3,048 meters). It's not exclusive to Kilimanjaro climbing, it can occur to anyone anywhere if you are climbing too high too fast.
Common AMS symptoms include nausea, dizziness, shortness of breath, headaches, confusion, and lack of coordination. If these symptoms appear, you might need to halt your climb to avoid more serious conditions like High Altitude Cerebral Edema (HACE) or High Altitude Pulmonary Edema (HAPE).
So, how does Diamox help?
Acetazolamide can aid in preventing or reducing AMS effects. According to the Mayo Clinic, Diamox is "fairly effective in preventing many cases of altitude illness." Specifically, it makes your blood slightly more acidic. This triggers your body to believe there's excess carbon dioxide, prompting deeper and faster breathing to rid your body of it. This results in more oxygen entering your bloodstream, aiding in acclimatizing to high altitudes and minimizing AMS symptoms.
Using Diamox on Kilimanjaro:
Diamox is available only through a doctor's prescription and isn't available over-the-counter. To use it, plan ahead and consult a doctor for a prescription.
The usual dose is 125 mg twice daily—once in the morning and once at lunch—preferably during activity rather than sleep. Start taking Diamox 24-48 hours before climbing and continue during ascent and at high altitude. You can stop taking it once you begin descending.
It's wise to test how your body reacts to Diamox before your climb, especially for potential allergies. Two weeks before departure, take the recommended dose for a few days to monitor for side effects. Side effects are common during the initial days of use, which is why a test run is beneficial.
As your body adjusts, you might experience headaches, increased urination, dizziness, dry mouth, loss of appetite, drowsiness, blurred vision, or tingling in hands or feet. Interestingly, these side effects bear similarity to AMS symptoms.
Is Diamox for You?
Not all trekkers require Diamox for reaching Uhuru Peak. However, first-time hikers and those new to high altitudes might find it useful as a precaution.
While Diamox has benefits, there are drawbacks too:
● It's a diuretic, causing dehydration and potentially hastening AMS development. Frequent urination becomes necessary, even during nighttime.
● Tingling sensations in hands, feet, and face might occur, but they're not harmful.
● Diamox doesn't prevent all AMS cases. It helps with minor symptoms, not serious AMS. It's important to know that Diamox doesn't cure AMS.
● If AMS is present, Diamox won't help; descending to lower altitude is the only solution.
The best way to prevent AMS is gradual ascent. It's the most effective way to summit safely.
Can I buy Diamox in Moshi, Tanzania?
Diamox is available at Kibo Pharmacy in Moshi town, conveniently located near the Moshi bus stand, a prominent landmark. This reputable pharmacy is widely recognized and the locals should be able to direct you to it.
In Conclusion
Consider Diamox if you've had AMS symptoms or if you're new to high altitudes. Consult your doctor to discuss risks and benefits and test Diamox's effects on your body before your climb.
Remember, Diamox can aid with altitude sickness symptoms, but a slower climb is the surest way to a successful summit, supported by proper hydration and guided monitoring of your health.
Your safety is paramount, whether or not you choose to use Diamox.
