Acetazolamide product information 



Acetazolamide bellongs to a group of medicines called carbonic anhydrase inhibitor. It helps to speed up the process of adjustment (acclimatisation) of your body to the higher altitude.

It is important to note that most climbers do not need to take acetazolamide tablets (Diamox). The best way to reduce the risk is to ascend slowly, get plenty of rest and fluids when you feel symptoms appearing and be prepared to descend if symptoms worsen. For more information on medical information and symptoms, please read the medical details on our altitude sickness page.


How to take 


You should take acetazolamide exactly as your doctor tells you to. The information will also be shown on the medicine label. Take the tablets with a drink of water. 


Side effects of acetazolamide 


Like all medicines, acetazolamide can cause some side effects, although not everyone gets them. 

Common side effects include feeling dizzy or sleepy and headache. If you feel dizzy or sleepy, get plenty of rest and do not drive or use machinery. 

It is also helpful that you take acetazolamide after food to prevent some side effects such as stomach pain or diarrhoea.


In rare cases, acetazolamide can cause skin reactions. If you experience unusual skin rash, speak with your doctor and pharmacist for advice.



Cautions


Acetazolamide must NOT be used in pregnant women. It may be used in breast-feeding women but you need to check with your doctor or pharmacist for advice before taking it. 


It can interact with a number of other medicines, such as some blood pressure or heart medications and blood thinning medicine warfarin. If you are unsure whether it can be taken with your current medications, check with a doctor or pharmacist.


If you have or have had kidney or lung problems, or an eye condition called glaucoma, you should consult a doctor before taking acetazolamide.
