This medicine may cause some people to feel drowsy, dizzy, lightheaded, or more tired than they are normally. Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are not alert.
It is important that your doctor check your progress at regular visits. Your doctor may want to do certain tests to see if the medicine is working properly or to see if certain side effects may be occurring without your knowing it.
This medicine may cause a loss of potassium from your body. To help prevent this, your doctor may want you to eat or drink foods that have a high potassium content (for example, orange or other citrus fruit juices) or take a potassium supplement. It is very important to follow these directions. Also, it is important not to change your diet on your own. This is more important if you are already on a special diet (as for diabetes) or if you are taking a potassium supplement. Extra potassium may not be necessary and, in some cases, too much potassium could be harmful.
For diabetic patients:
- This medicine may raise blood and urine sugar levels. While you are using this medicine, be especially careful in testing for sugar in your blood or urine. If you have any questions about this, check with your doctor.
Your doctor may want you to increase the amount of fluids you drink while you are taking this medicine. This is to prevent kidney stones. However, do not increase the amount of fluids you drink without first checking with your doctor.
For patients taking acetazolamide as an anticonvulsant:
- If you have been taking acetazolamide regularly for several weeks or more, do not suddenly stop taking it. Your doctor may want you to reduce gradually the amount you are taking before stopping completely.
