Dalacin C capsules contain the active ingredient clindamycin hydrochloride, which is a type of medicine called an antibiotic. It is used to treat infections with bacteria. Clindamycin is also available without a brand name, ie as the generic medicine.
Clindamycin works by preventing bacteria from producing proteins that are essential to them. Without these proteins the bacteria cannot grow, replicate and increase in numbers. The remaining bacteria eventually die or are destroyed by the immune system. This treats the infection.
Clindamycin is active against a wide variety of Gram positive bacteria, including streptococci, pneumococci and staphylococci (including MRSA). It is also effective against a group of bacteria known collectively as anaerobic bacteria. This type of bacteria do not need oxygen to grow and multiply. Anaerobic bacteria can cause infections in areas of the body such as the bones, gut, pelvic cavity and gums. Clindamycin is used to treat these types of infections, as well as skin and soft tissue infections such as leg ulcers and pressure sores.
Clindamycin is not a widely used antibiotic because it is associated with a higher risk of developing antibiotic-associated colitis (inflammation of the colon) than other antibiotics. This colitis usually results in severe diarrhoea and clindamycin should be stoppped immediately if this occurs. See the warning section below for more information.
To make sure the bacteria causing an infection are susceptible to clindamycin your doctor may take a tissue sample, for example a blood sample or swab from the skin.
Clindamycin is usually reserved for treating serious infections such as those below, when treatment with other types of antibiotic, such as penicillins, macrolides or metronidazole, has not been effective.
This medicine should not be used if you are allergic to any of its ingredients. Please inform your doctor or pharmacist if you have previously experienced such an allergy.

Certain medicines should not be used during pregnancy or breastfeeding. However, other medicines may be safely used in pregnancy or breastfeeding providing the benefits to the mother outweigh the risks to the unborn baby. Always inform your doctor if you are pregnant or planning a pregnancy, before using any medicine.
Medicines and their possible side effects can affect individual people in different ways. The following are some of the side effects that are known to be associated with this medicine. Just because a side effect is stated here, it does not mean that all people using this medicine will experience that or any side effect.
Prolonged treatment with antibiotics can sometimes cause overgrowth of other organisms that are not susceptible to the antibiotic, for example fungi or yeasts such as Candida. This may sometimes cause infections such as thrush. Tell your doctor if you think you have developed a new infection during or after taking this antibiotic.
The side effects listed above may not include all of the side effects reported by the medicine's manufacturer.
For more information about any other possible risks associated with this medicine, please read the information provided with the medicine or consult your doctor or pharmacist.
It is important to tell your doctor or pharmacist what medicines you are already taking, including those bought without a prescription and herbal medicines, before you start taking this medicine. Similarly, check with your doctor or pharmacist before taking any new medicines while using this one, to make sure that the combination is safe.
Clindamycin may enhance the effects of suxamethonium, which is a medicine used to help relax muscles during surgery. If you are going to have surgery under a general anaesthetic you should make sure that the medical staff know you are taking this antibiotic.
Clindmaycin may oppose the effects of neostigmine and pyridostigmine used to treat myaesthenia gravis.
Oral typhoid vaccine (Vivotif) should not be taken until at least three days after you have finished a course of this antibiotic, because the antibiotic could make this vaccine less effective.
In the past, women using hormonal contraception such as the pill or patch would be advised to use an extra method of contraception (eg condoms) while taking an antibiotic like this one and for seven days after finishing the course. However, this advice has now changed. You no longer need to use an extra method of contraception with the pill, patch or vaginal ring while you take a course of antibiotics. This change in advice comes because to date there is no evidence to prove that antibiotics (other than rifampicin or rifabutin) affect these contraceptives. This is the latest guidance from the Faculty of Sexual & Reproductive Healthcare.
However, if you are taking the contraceptive pill and experience vomiting or diarrhoea as a result of taking this antibiotic, you should follow the instructions for vomiting and diarrhoea described in the leaflet provided with your pills.
Clindamycin capsules and injection are also available without a brand name, ie as the generic medicine.
