This prescription item requires a pre approved authority from the Government in order to get this item at the quoted price. Authority prescriptions need to be applied for by the doctor writing the script and can include reasons such as increased quantities due to dosage, increased repeats, use for a pre determined specified use, or the nature of the medication itself requiring specialist interaction.

This item contains more than one pack of a prescription product. Before this can be dispensed the doctor has to give approval. The prescription must be written for the total quantity or the prescription must be endorsed by your doctor "Regulation 24" otherwise we will be unable to dispense the increased amount. If you proceed with the order without approval, we will only send out one pack at the single pack price and refund the difference. Eg If your prescription is written out for 30 Tablets with 5 repeats and it does not have “Regulation 24 “ written on the script, the ONLY quantity we can dispense is 30 at one time. Further dispensing of this product could only occur after an appropriate length of time - usually 21 days but depends on dosage. In this example if you would like to obtain 180 Tablets then the doctor must endorse the prescription “Regulation 24” or the quantity must be written out for 180 and not 30. NB Conditions apply on the writing of a Regulation 24 prescription. Ask your doctor or pharmacist for details.

We can no longer accept signed authority forms from your doctor as permission to dispense more than one pack. Please contact our pharmacist for more information.

If you order this item as Private, NO PBS stickers will be issued. Once any prescription order has been sent the product cannot be returned for a refund even if your doctor changes your medication or you have an adverse reaction.

General Information

Consumer Medicine Information

What is in this leaflet

This leaflet answers some common questions about DIAMOX. It does not contain all of the available information. It does not take the place of talking to your doctor or pharmacist.

All medicines have risks and benefits. Your doctor has weighed the risks of you taking DIAMOX against the benefits they expect it will have for you. If you have any concerns about taking this medicine, ask your doctor or pharmacist.

Keep this leaflet with the medicine.

You may need to read it again. What DIAMOX is used for DIAMOX is used to lower raised pressure in the eye and to treat the following forms of glaucoma:
Chronic simple (open-angle) glaucoma
Secondary glaucoma, where glaucoma has developed as a result of other eye disorders
Acute angle-closure glaucoma before undergoing surgery.

Glaucoma is the name given to a group of eye diseases in which the optic nerve at the back of the eye is slowly destroyed. In most people this damage is caused by increased pressure in the eye. However, some people with glaucoma may have normal eye pressure. Glaucoma is usually caused by a build up of fluid which flows into the eye. This build up occurs because the fluid drains out of your eye more slowly than it is being pumped in. Since new fluid continues to enter the eye, joining the fluid that is already there, the pressure continues to rise. This raised pressure may damage the back of the eye, resulting in gradual loss of sight. Damage can progress so slowly that the person is not aware of this gradual loss of sight. Sometimes even normal eye pressure is associated with damage to the back of the eye. There are usually no symptoms of glaucoma. The only way of knowing is to have your eye pressure, optic nerve, and visual field checked by an eye specialist or optometrist. If glaucoma is not treated it can lead to serious problems. You may have no symptoms but eventually glaucoma can lead to total blindness. In fact, untreated glaucoma is one of the most common causes of blindness. DIAMOX is used, either alone or in combination with other eye drops or medicines, to lower raised pressure within your eyes. DIAMOX is also used to help treat some other conditions such as:
Fluid retention due to congestive heart failure
Fluid retention caused by other medicines
Epilepsy in both adults and children

Ask your doctor if you have any questions about why DIAMOX has been prescribed for you.

Your doctor may have prescribed DIAMOX for another purpose. DIAMOX works by blocking an enzyme, which is responsible for fluid formation. In people with glaucoma, blocking this enzyme causes the pressure in the eye caused by fluid build up to fall. Blocking this enzyme also seems to slow down abnormal or excessive discharge from your nerves. This helps prevent fits in people with epilepsy. DIAMOX also acts as a diuretic. This gets rid of excess fluid in the body by increasing urine production. This action helps people with congestive heart failure or fluid retention caused by other medicines. DIAMOX is not addictive. This medicine is available only with a doctor's prescription. Before you take DIAMOX When you must not take it

Do not take DIAMOX if:
1. you are allergic to:
DIAMOX or any of the ingredients listed at the end of this leaflet
medicines called sulphonamides, which are a group of antibiotics used to treat bacterial infections, or sulphonamide related medicines

Some of the symptoms of an allergic reaction to DIAMOX or sulphonamides may include fever, rash and crystals in the urine.
2. you have chronic noncongestive angle closure glaucoma.
3. you have any of the following conditions:
marked liver or kidney disease

If you have chronic liver disease and you take DIAMOX you are at risk of brain and nervous system damage.
problems with your adrenal glands
unusual amounts of salt in the body
low levels of sodium, potassium or bicarbonate in your blood
4. you are pregnant.

DIAMOX should not be used in pregnancy, especially during the first trimester.

Do not use DIAMOX if the packaging is torn or shows signs of tampering.

Do not use DIAMOX after the expiry date (EXP) printed on the pack.

If you take it after the expiry date has passed, it may not work as well. Before you take it

You must tell your doctor if:
1. you have any allergies to:
any other medicines
any other substances, such as foods, preservatives or dyes
2. you are pregnant or plan to become pregnant.

Your doctor will discuss the risks and benefits of taking DIAMOX during pregnancy.
3. you are breastfeeding or plan to breastfeed.

Your doctor will discuss the risks and benefits of taking DIAMOX when breastfeeding. DIAMOX has been found in low levels in breast milk.
4. you have or have had any other medical conditions including:
blockages in the lung
diabetes or impaired glucose tolerance

If you have not told your doctor about any of the above, tell them before you take any DIAMOX.

Taking other medicines

Tell your doctor if you are taking any other medicines, including medicines that you buy without a prescription from a pharmacy, supermarket or health food shop.

Some medicines may reduce or increase the action of DIAMOX. Also DIAMOX may reduce or increase the action of some other medicines. These include:
phenytoin, primidone, medicines used to treat epilepsy

medicines used for high blood pressure

You may need to take different amounts of your medicine or you may need to take different medicines.

Your doctor or pharmacist has more information on medicines to be careful with or avoid while taking DIAMOX. How to take DIAMOX How much to take

The dose of DIAMOX may be different for each person. Your doctor will decide the right dose for you.

The usual dose for chronic simple (open-angle) glaucoma is 250 mg (1 tablet) to 1 gram (4 tablets) per 24 hours. If the dose per 24 hours is greater than 250 mg, then the tablets are taken in divided doses. For secondary glaucoma and for use before surgery in people with acute closed-angle glaucoma, the usual dose is 250 mg every 4 hours. For epilepsy, the recommended dose for children is based on their bodyweight. Children take 8 - 30 mg per kilogram of bodyweight a day in divided doses. The total daily dose must not be greater than 750 mg per day. This equals three tablets a day. For adults with epilepsy the usual dose is 250 mg (1 tablet) to 1 gram (4 tablets) daily in divided doses. If you are taking DIAMOX with another medicine for your epilepsy, the starting dose for DIAMOX is usually 250 mg once daily in addition to your epilepsy medicine. For congestive heart failure, the usual starting dose is 250 mg to 375 mg once daily in the morning. For fluid retention caused by other drugs, the usual dose is 250 mg to 375 mg once daily for 1 to 2 days, alternating with a day of rest. How to take it

Swallow DIAMOX with a glass of water.

DIAMOX may be taken with or without food. When to take it

If you are taking DIAMOX in divided doses, take your tablets at evenly spaced time periods over a 24-hour period.

For congestive heart failure, take DIAMOX in the morning.

For congestive heart failure and drug-induced fluid retention, if your doctor prescribes two days therapy of DIAMOX, take DIAMOX on the first day, then no DIAMOX the next day and then the second dose on the third day.

DIAMOX gets rid of excess fluid best when given every other day over a three day period. Follow your doctor's dosing instructions if they are different from the instructions given in this leaflet.

How long to take it

For congestive heart failure and fluid retention caused by other medicines, do not take DIAMOX for longer than your doctor says.

DIAMOX may not work as well if too many doses are given. For glaucoma DIAMOX helps control your condition, but does not cure it. Therefore you must take DIAMOX every day.

Continue taking the tablets for as long as your doctor tells you. If you forget to take it

If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to. Otherwise, take it as soon as you remember, and then go back to taking it as you would normally.

Do not take a double dose to make up for the dose that you missed.

If you are unsure about whether to take your next dose, speak to your doctor or pharmacist.

If you have trouble remembering when to take your medicine, ask your pharmacist for some hints. If you take too much (overdose)

Immediately telephone your doctor or Poisons Information Centre on 131 126 for advice, or go to accident and emergency at your nearest hospital, if you think that you or anyone else may have taken too much DIAMOX. Do this even if there are no signs of discomfort or poisoning. Also report any other medicine or alcohol, which has been taken. You may need urgent medical attention. Keep telephone numbers for these places handy.
