Before you start to take it

You must tell your doctor about all of the following before you start to take CLINDAMYK.

Tell your doctor if you have allergies to any other medicines, foods, preservatives or dyes.

Tell your doctor if you pregnant or intend to become pregnant. Clindamycin crosses the placenta therefore CLINDAMYK capsules should only be used in pregnancy if clearly needed. Your doctor will discuss the risks and benefits of taking CLINDAMYK during pregnancy.

Some medicines and CLINDAMYK may interfere with each other. These include:

  • erythromycin, an antibiotic
  • medicines used for muscle relaxation in anaesthesia

These medicines may be affected by CLINDAMYK or may affect how well it works. You may need different amounts of your medicines, or you may need to take different medicines.

Your doctor and pharmacist have more information on medicines to be careful with or avoid while taking this medicine.

How to take CLINDAMYK capsules

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

You may be given a different dosage depending on your condition and how you react to the medicine.

If you do not understand the instructions in this leaflet, ask your doctor or pharmacist for help.

How much to take

One (1) capsule (150 mg) every six hours is the usual dose. The number of capsules may increase with more serious infections. Your doctor will tell you how long to take your capsules.

CLINDAMYK capsules are not recommended in children for formulation reasons.

How to take it

CLINDAMYK capsules should be taken by mouth, with a full glass of water.

When to take it

CLINDAMYK can be taken with or without food, it does not matter.

How long to take it

Your doctor will tell you how long to take your capsules.

Continue taking CLINDAMYK until you finish the box or until your doctor recommends.

Check with your doctor if you are not sure how long you should be taking it.

Do not stop taking CLINDAMYK capsules because you are feeling better. If you do not complete the full course prescribed by your doctor, all of the bacteria causing your infection may not be killed. These bacteria may continue to grow and multiply so that your infection may not clear completely or may return.

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, then go back to taking your capsules as you would normally.

If you are not sure whether to skip the dose, talk to your doctor or pharmacist.

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

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

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

If you take too much (overdose)

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

While you are taking CLINDAMYK capsules

Things you must do

If the symptoms of your infection do not improve within a few days, or if they become worse, tell your doctor.

If you get severe diarrhoea, tell your doctor, pharmacist or nurse immediately. Do this even if it occurs several weeks after you have stopped taking CLINDAMYK. Diarrhoea may mean that you have a serious condition affecting your bowel. You may need urgent medical care. Do not take any medicines for diarrhoea without first checking with your doctor.

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