Dalacin C Capsules

What Dalacin C capsules are used for

Dalacin C is an antibiotic. It is used to treat infections in different parts of the body caused by bacteria.

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

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

Dalacin C is recommended for patients who are allergic to penicillin or patients for whom penicillin is not suitable.

Your doctor may have prescribed Dalacin C for another reason. Ask your doctor if you have any questions about why Dalacin C has been prescribed for you.

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

Dalacin C is not addictive.

If you are not sure whether you should start taking Dalacin C capsules, talk to your doctor.

Before you start to take Dalacin C capsules

You must tell your doctor about all of the following before you start to take Dalacin C:

1. if you have any allergies to any other medicines or any other substances such as foods, preservatives or dyes.

2. if you are pregnant or intend to become pregnant

Clindamycin crosses the placenta therefore Dalacin C capsules should only be used in pregnancy if clearly needed. Your doctor will discuss the risks and benefits of taking Dalacin C during pregnancy.

Dalacin C capsules are not recommended during breastfeeding.

4. if you have or have ever had:

If you have not told your doctor or pharmacist about any of the above, do so before you start taking Dalacin C capsules.

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.

There may be interference between Dalacin C and some other medicines including:

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

These medicines may be affected by Dalacin C or may affect how well Dalacin C works. You may need different amounts of your medicine or you may need to take different medicines. Your doctor or pharmacist may have more information on medicines to be careful with or avoid while taking Dalacin C.

How to take Dalacin C capsules

Your doctor or pharmacist will tell you how to take your Dalacin C capsules.

Follow all directions given to you by your doctor and pharmacist carefully.

Their directions 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.

The directions your doctor or pharmacist gives you should be strictly followed.

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

How much to take and how long to take it


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.


Dalacin C capsules are not recommended in children for formulation reasons.

Continue taking Dalacin C 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 Dalacin C 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.

How to take it and when to take it

Dalacin C capsules should be taken by mouth, with a full glass of water. Dalacin C can be taken with or without food, it does not matter.

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 double a dose to make up for the dose you have missed.

If you take too much (overdose)

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

Keep telephone numbers for these places/services handy. Have the Dalacin C box or this leaflet available to give details if needed.

While you are taking Dalacin C 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 Dalacin C.

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 Dalacin C, 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 Dalacin C allows fungi/yeast to grow and the above symptoms to occur. Dalacin C does not work against fungi/yeast.

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

If you are about to start taking any new medicines, tell your doctor and pharmacist that you are taking Dalacin C.

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

If you feel that Dalacin C is not helping your condition, tell your doctor.

Tell your doctor if, for any reason, you have not used Dalacin C exactly as prescribed.
