What Fasigyn is used for

Fasigyn is used to:

  • treat certain infections of the male and female genital systems, liver and bowel
  • prevent certain infections that may occur during surgery.

Fasigyn is an antibiotic, which belongs to a group of medicines called nitroimidazoles.

Fasigyn works by killing or stopping the growth of bacteria causing your infection.

Fasigyn will not work against viral infections such as colds or flu.

Your doctor, however, may prescribe Fasigyn for another purpose.

Ask your doctor if you have any questions about why Fasigyn has been prescribed for you. This medicine is available only with a doctor's prescription.

Taking other medicines

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

Some medicines may interfere with Fasigyn. These include:

How to take Fasigyn

Follow all directions given to you by your doctor or pharmacist carefully. They may differ from the information contained in this leaflet.

If you do not understand the instructions on the pack, ask your doctor or pharmacist for advice.

How much to take

Adults

Fasigyn is usually given as a single dose of four tablets, to be taken at the same time.

However, depending on your condition and how you react to the medicine, your doctor may ask you to take some other dose or take it for a longer time.

Children

For children, the dose depends on body weight.

How long to take

Your doctor will tell you how long you need to keep taking Fasigyn.

In some cases, you may need to take Fasigyn for up to ten days.

How to take it

Swallow the tablets with liquid.

When to take it

Take Fasigyn during or immediately after a meal. If taken on an empty stomach, it may cause stomach upset, nausea or vomiting.

If you forget to take it

If you are taking more than a single dose of Fasigyn and 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, then go back to taking it as you would normally.

Do not try to make up for missed doses by taking more than one dose at a time. This may increase the chance of you getting an unwanted side effect.

If you are not sure what to do, check with your doctor or pharmacist.

If you have trouble remembering to take your Fasigyn, ask your pharmacist for some hints.

If you take too much (overdose)

Immediately telephone your doctor or Poisons Information Centre (telephone in Australia - 13 11 26) for advice, or go to Accident and Emergency (Casualty) at your nearest hospital if you think you or anyone else may have taken too much Fasigyn. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.

Keep telephone numbers of these places handy.

If you take too many tablets, you may get an upset stomach, diarrhoea or skin rashes.

After using Fasigyn

Storage

Keep Fasigyn in its original packaging until it is time to use it. If you take Fasigyn out of its packaging, it may not keep as well.

Keep your Fasigyn in a cool, dry place where it stays below 25°C.

Do not store Fasigyn or any other medicine in the bathroom or near a sink. Do not leave it in the car or on a window sill. Heat and dampness can destroy some medicines.

Keep your Fasigyn where young children cannot reach it. A locked cupboard at least one and a half metres above the ground is a good place to store medicines.

Disposal

If your doctor tells you to stop taking Fasigyn, or the tablets have passed their expiry date, ask your pharmacist what to do with any left over.
