Acetazolamide for glaucoma

About acetazolamide

An increase in pressure within your eye can lead to damage to the optic nerve at the back of your eye. When this occurs it is called glaucoma. גלאוקומה can lead to a loss of vision if it is not treated. Treatment with acetazolamide helps to reduce eye pressure, and this helps to prevent further eye damage. You will also be given other medicines to help reduce the pressure in your eyes, commonly as eye drops.

Acetazolamide works by blocking the action of an enzyme called carbonic anhydrase. Blocking this enzyme reduces the amount of fluid (called aqueous humour) that you make in the front part of your eye, and this helps to lower the pressure within your eye.

Acetazolamide is sometimes prescribed for other conditions which are not covered by this leaflet. If you have been prescribed it to remove excess water from your body, to prevent altitude sickness or to help treat epilepsy, speak with your doctor if you need further advice.

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking acetazolamide it is important that your doctor knows:

• אם את בהריון או מניקה.

• If you have liver or kidney problems, or difficulty passing urine.

• If you have diabetes mellitus, a condition which causes raised blood sugar levels.

• If you have breathing problems.

• If you have problems with your adrenal glands, such as מחלת אדיסון.

• If you have been told you have low amounts of potassium or sodium, or high levels of chloride in your blood.

• אם אתה נוטל תרופות אחרות כלשהן. זה כולל כל תרופה שאתה נוטל שניתן לרכוש ללא מרשם, כמו גם תרופות צמחיות ומשלימות.

• If you have ever had an allergic reaction to a medicine. It is particularly important that you tell your doctor if you are allergic to sulfonamide antibiotics.

• Before you start this treatment, read the manufacturer's printed information leaflet from inside your pack. The manufacturer's leaflet will give you more information about acetazolamide and a full list of the side-effects which you may experience from taking it.

• Your doctor will prescribe you a dose that is suited to your condition, so take acetazolamide exactly as your doctor tells you to. If you are taking tablets, it will be between 1-4 tablets daily, taken in divided doses over the day. If you are taking capsules, it will be 1 or 2 capsules daily. Your dose will be printed on the label of your pack to remind you what your doctor said.

• If you are taking capsules (brand Diamox® SR), they are specially formulated to release the medicine they contain slowly during the day to give a more even effect. Do not chew or open the capsules as this will stop them from working as intended.

• Try to take your doses at the same times of day each day, as this will help you to remember to take acetazolamide regularly. You can take your doses either just before or just after meals.

• If you forget to take a dose, take it as soon as you remember unless your next dose is due. If your next dose is due, then take the dose which is due but leave out the forgotten one. Do not take two doses together to make up for a missed dose.

• Keep your regular appointments with your doctor so that your progress can be monitored.

• Your doctor will tell you how long you will need to take acetazolamide for. It is not generally recommended for long-term use, so if you need to take it over an extended period of time, your doctor will want you to have some blood tests.

• You should also let your doctor know if you develop an unusual skin rash while you are on acetazolamide.

• If you buy any medicines, check with a pharmacist that they are safe to take alongside acetazolamide.

• If you are having an operation or any medical treatment, remember to tell the person carrying out the treatment which medicines you are taking or using.

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the most common ones associated with acetazolamide. You will find a full list in the manufacturer's information leaflet supplied with your medicine. The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.
