Acetazolamide - Dosage and How to Use

How should Acetazolamide be used?

Acetazolamide may be taken 2 to 3 times a day. The doctor may start your child on a low dose and then slowly increase the dose. Follow the instructions on the label carefully and ask your pharmacist or doctor if you are unsure.

Do not take this medication more often than directed and do not stop unless instructed by the doctor. Stopping this medicine too rapidly can increase the risk of seizures.


Swallow the tablets whole with a glass of water. If your child is unable to swallow the tablet, you may crush it and add it to small amount of food (i.e. yogurt, ice-cream, syrup) before giving it to your child. Acetazolamide may be taken with or without food.

It is important to drink adequate amount of fluids when your child is taking acetazolamide.


What should I do if I miss a dose?

Give your child the dose as soon as you remember and then continue to take it as you normally give. However, if it is almost time for the next dose, skip the dose you missed and give the next dose at the usual time.

Do not double or increase the dose.

If your child has missed more than two doses or you are not sure of what to do, consult your doctor or pharmacist.

If your child has less than two weeks medication supplies, please ensure that you have made an appointment with your child’s neurologist or arranged to collect more medication.
