Indication: What Simplotan is used for

Simplotan is used to:

  • Treat certain infections of the male and female genital systems, liver and bowel;

This medicine is available only with a doctor’s prescription.

Action: How Simplotan works

Simplotan 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.

Tinidazole has been shown to be effective against:

  • Trichomonas vaginalis;
  • Entamoeba histolytica; and
  • Giardia lamblia.

Tinidazole 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.

Simplotan contains 500mg of tinidazole per tablet as the active ingredient. It also contains microcrystalline cellulose, alginic acid (400), maize starch, magnesium stearate (470), sodium lauryl sulfate, hypromellose, propylene glycol (1520), and titanium dioxide.

Before you start to take it

You must tell your doctor if:

  • You have any allergies to:
    • Any other medicines;
    • Any other substances, such as foods, preservatives or dyes;
  • You are pregnant or intend to become pregnant. Like most other medicines, Simplotan is not recommended in pregnancy. However, your doctor will discuss the possible risks and benefits of taking Simplotan during pregnancy;
  • You are breastfeeding or plan to breastfeed. Like most other medicines, Simplotan is not recommended for breastfeeding. However, your doctor will discuss the possible risks and benefits of taking Simplotan during breastfeeding;
  • You have or have had any other medical conditions, including any kidney problems;
  • You drink alcohol, even occasionally. Do not drink during and for 3 days after stopping treatment with Simplotan. If you drink alcohol with Simplotan it may make you feel sick, vomit, have stomach cramps, headache or flushing.

If you have not told your doctor about any of the above, tell them before you are given Simplotan.

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 Simplotan. These include:

  • Warfarin or other medicines used to prevent blood clots.

These medicines may be affected by Simplotan or may affect how well it works.

Your doctor or pharmacist has more information on medicines to be careful with or avoid while taking Simplotan.

Do not take medicines that contain alcohol (e.g. cough syrups) while using, or for three (3) days after stopping Simplotan.

Talk to your doctor about the need for an additional method of contraception while taking Simplotan. Some antibiotics may decrease the effectiveness of some birth control pills, although this has not been shown with Simplotan.

How to take Simplotan

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

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

How much to take

Adults

Simplotan 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 Simplotan.

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

How to take it

Swallow the tablets with liquid.

When to take it

Take Simplotan during or immediately after a meal.

If taken on an empty stomach, it may cause stomach upset.

If you forget to take it

If you are taking more than a single dose of Simplotan and 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 Simplotan, 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 Simplotan. 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 Simplotan

Things you must do

If you become pregnant while taking Simplotan, tell your doctor immediately.

If you get a sore, white mouth or tongue while taking, or soon after stopping Simplotan, tell your doctor or pharmacist. If you get vaginal itching, burning or a white discharge while taking, or soon after stopping Simplotan, tell your doctor or pharmacist. This may mean you have a yeast infection called thrush. Sometimes the use of Simplotan allows yeast to grow and the above symptoms to occur. Simplotan does not work against yeast.

If you are about to start taking any new medicines, tell your doctor or pharmacist that you are taking Simplotan.

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

Things you must not do

Do not give Simplotan to anyone else, even if they have the same condition as you.

Do not use Simplotan to treat any other medical complaints unless your doctor tells you to.

After using Simplotan

Storage

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

Keep your Simplotan in a cool, dry place where it stays below 25 degrees Celsius. Do not store Simplotan 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 Simplotan where young children cannot reach it. A locked cupboard at least 1 1/2 metres above the ground is a good place to store medicines.

Disposal

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

Schedule of Simplotan

Simplotan is a Schedule 4 (prescription only) medicine.
