Print Friendly, PDF & Email

Generic Name: clindamycin phosphate
Product Name: Dalacin T

Indication: What Dalacin T is used for

Dalacin T is an antibiotic lotion used on the skin to help treat acne.

Dalacin T is not addictive.

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

Action: How Dalacin T works

Dalacin T works by decreasing acne lesions and/or stopping the growth of skin bacteria that cause acne.

Clindamycin phosphate is a prodrug which is converted to its biologically active form, clindamycin, by phosphate hydrolysis. Cross-resistance has been demonstrated between clindamycin and lincomycin. Antagonism has been demonstrated between clindamycin and erythromycin. Clindamycin in vitro inhibits all Propionibacterium acnes cultures tested. Free fatty acids on the skin surface have been decreased from approximately 14% to 2% following application of a 1% clindamycin solution containing alcohol.

Dalacin T Lotion contains clindamycin phosphate equivalent to clindamycin 10 mg/mL as the active ingredient.

It also contains glycerol, sodium lauroyl sarcosinate, stearic acid, glyceryl monostearate, mono- and diglycerides, potassium hydroxide, cetostearyl alcohol, isostearyl alcohol, purified water and methyl hydroxybenzoate.

    • Symptoms of an allergic reaction may include skin rash and itching;
  • If the packaging shows signs of tampering;

Before you start to use it

You must tell your doctor if:

If you have not told your doctor about any of the above, tell them before you use Dalacin T.

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 Dalacin T. These include:

  • The antibiotic erythromycin;
  • Neuromuscular blocking medicines (certain agents used for muscle relaxation in anaesthesia).

These medicines may be affected by Dalacin T or may affect how well it works. You may need different amounts of your medicine or you may need to take different medicines. Your doctor will advise you.

Your doctor or pharmacist may have more information on medicines to be careful with or avoid while using Dalacin T.

How to use Dalacin T

How much to use and how to use it

Shake the bottle immediately before use. Apply a thin layer twice a day to the affected areas of the skin.

Avoid contact with eyes, lips and mucous membranes.

Follow all directions given to you by your doctor and pharmacist carefully. They may differ from the information contained here. If you do not understand the instructions on the label, ask your doctor or pharmacist for help.

How long to use it

Continue using Dalacin T for as long as your doctor recommends. If you are not sure how long you should be using Dalacin T, check with your doctor.

If your acne does not improve within 6 weeks, or if it becomes worse, contact your doctor. However, treatment of acne may take up to 8 to 12 weeks before full improvement is seen.

If you forget to use it

Apply Dalacin T Lotion when you remember, unless it is almost time for your next application, in which case wait and apply at the next application time.

If you use too much

If you use too much Dalacin T, you may experience some of the side effects listed below under side effects.

While you are using Dalacin T

Things you must do

If you become pregnant while you are using Dalacin T, tell your doctor.

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

Things you must not do

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

After using Dalacin T


Keep Dalacin T in a cool, dry place where the temperature stays below 25°C. Do not store it, or any other medicine, in a bathroom or near a sink. Do not leave it in the car or on window sills. Heat and dampness can destroy some medicines.

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


If your doctor tells you to stop using Dalacin T, ask your pharmacist what to do with any lotion left over.

Schedule of Dalacin T

Dalacin T is a Schedule 4 (prescription only medicine).

Side effects of Dalacin T

Tell your doctor or pharmacist as soon as possible if you do not feel well while you are using Dalacin T. Check with your doctor as soon as possible if you have any problems while using Dalacin T, even if you do not think they are connected with the medicine or are not listed here. Like other medicines, Dalacin T can cause some side effects. If they occur, most are likely to be minor and temporary. However, some may be serious and need medical attention.

Do not be alarmed by this list of possible side effects. You may not experience any of them.

Ask your doctor or pharmacist to answer any questions you may have.

Tell your doctor if you notice any of the following and they worry you:

  • Skin irritation (burning, redness, peeling);
  • Itchy skin;
  • Dry skin;
  • Hives;
  • Skin oiliness;
  • Stomach upset (diarrhoea, nausea, vomiting);
  • Stomach pain.

These side effects are usually mild.

Tell your doctor immediately if you notice any of the following side effects during use, or several weeks after stopping treatment with Dalacin T:

  • Severe stomach cramps;
  • Watery and severe diarrhoea, which may also be bloody;
  • Fever, in combination with one or both of the above.

These are rare but serious side effects. Dalacin T can change bacteria, which are normally present in the bowel and harmless, to multiply and therefore cause the above symptoms. You may need urgent medical attention. This side effect is rare.

Do not take any diarrhoea medicine without first checking with your doctor.

Ask your doctor or pharmacist if you don’t understand anything on this list. Other side effects not listed above may also occur in some patients.

Tell your doctor if you notice anything else that is making you feel unwell.
