Acetazolamide for Eye Conditions (245kB)
What is Acetazolamide and what is it used for?
Acetazolamide is a medicine that can be used for a range of indications, most commonly for glaucoma and other eye conditions1. Acetazolamide inhibits an enzyme (carbonic anhydrase) in the eye to reduce the production of intra-ocular fluid. By reducing the amount of intra-ocular fluid, the pressure in the eye can be decreased.
Why is it important for my child to use this medicine?
Acetazolamide reduces the pressure within the eyes, which can help to prevent or reduce the risk of damage to the optic nerve in conditions such as glaucoma.
How much should I give?
Always follow the instructions on the label provided by pharmacy on your child’s medication. Your doctor may decide to prescribe the medicine multiple times per day, depending on the requirements of the patient.
How should I give it?
The medicine Acetazolamide is readily available as a 250mg tablet. In exceptional circumstances, if your child cannot take tablets or the dose cannot be easily obtained by using tablets, the Pharmacy Department is able to make a liquid medicine of Acetazolamide.
Always follow the instructions on the Pharmacy label on the box of tablets / bottle. This label will tell you how much medicine to give and how often.
What if I forget to give it?
You should always try to give the dose as soon as remembered. However, if you remember within 2 hours of the next dose, you should skip the dose that was missed and carry on with treatment as normal.
Are there any possible side effects?
Acetazolamide can cause some side effects. Common side effects can include:
Loss of appetite
Headache
Diarrhoea
Dizziness / looking flushed
Tiredness
If you are concerned about any side effect you think your child may be experiencing, please contact your doctor or pharmacist.
How do I store Acetazolamide?
Acetazolamide tablets are stored at room temperature, below 25oC.
Acetazolamide suspension is stored in a fridge, between 2-8oC. The suspension only has a 30 day expiry from the date of manufacture, so will require more frequent dispensing.
General advice about medicines

condition appears to be the same, as this could do harm. - If you think someone else may have taken the medicine by accident, contact your doctor straight away.
- Make sure that you always have enough medicine. Order a new prescription at least two weeks before you will run out.
- Make sure that the medicine you have at home has not reached the ‘best before’ or ‘use by’ date on the packaging. Give old medicines to your pharmacist to dispose of.
- This leaflet should be read with any manufacturers’ patient information. You must always discuss individual treatment with the appropriate member of staff.
