Action: How Fasigyn works
Fasigyn is an antibiotic, which belongs to a group of medicines called nitroimidazoles. It works by killing or stopping the growth of bacteria causing your infection. It will not work against viral infections such as colds or flu.
Fasigyn (tinidazole) has been shown to be effective against:
- Trichomonas vaginalis;
- Entamoeba histolytica;
- Giardia lamblia.
It has also been shown to be effective against anaerobic bacteria including:
- Bacteroides fragilis;
- Other species of Bacteroides;
- Fusobacteria spp.
Other organisms for which tinidazole is also bactericidal belong to species such as:
- Peptococcus spp.;
- Peptostreptococcus spp.;
- Clostridium spp. (except C. difficile);
- Eubacteria spp.
Aerobic and facultative aerobic bacteria, Arachnia, propionibacteria, and actinomycetes are resistant to tinidazole.
Fasigyn contains 500 mg of tinidazole per tablet as the active ingredient. It also contains microcrystalline cellulose, alginic acid (400), maize starch, magnesium stearate (470), sodium lauryl sulfate, and hypromellose.

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.
While you are taking Fasigyn
Things you must do
If you become pregnant while taking Fasigyn, tell your doctor immediately.
If you get a sore, white mouth or tongue while taking, or soon after stopping Fasigyn, tell your doctor or pharmacist. If you get vaginal itching, burning or a white discharge while taking, or soon after stopping Fasigyn, tell your doctor or pharmacist. This may mean you have a yeast infection called thrush.

Tell all doctors, dentists, and pharmacists who are treating you that you are taking Fasigyn.
