Patient leaflet - Clindamycin 75 mg capsules hard

1. What Clindamycin is and what it is used for

Clindamycin Capsules contain clindamycin which is an antibiotic used in the treatment of serious bacterial infections.

2. What you need to know before you take Clindamycin

Do not take Clindamycin Capsules:

  • if you are allergic to clindamycin, lincomycin or any of the other ingredients of this medicine listed in section 6.

Warnings and precautions

Talk to your doctor or pharmacist before taking Clindamycin Capsules if:

  • you have diarrhoea, or usually get diarrhoea when you take antibiotics, or have ever suffered from problems with your stomach, or intestines. If you develop severe, or prolonged, or bloody diarrhoea during, or after using Clindamycin Capsules, tell your doctor immediately since it may be necessary to interrupt the treatment. This may be a sign of bowel inflammation (pseudomembranous colitis) which can occur following treatment with antibiotics.
  • you suffer from problems with your liver.
  • you suffer from problems with your kidneys (see below).
  • you suffer from asthma, eczema or hayfever.
  • you develop any severe skin reactions or hypersensitivity to Clindamycin Capsules.

Acute kidney disorders may occur. Please inform your doctor about any medication you currently take and if you have any existing problems with your kidneys. If you experience decreased urine output, fluid retention causing swelling in your legs, ankles or feet, shortness of breath, or nausea you should contact your doctor immediately.

Clindamycin does not get into the brain and is therefore not suitable for treating serious infections in and around the brain. Your doctor may need to give you another antibiotic if you have these infections.

Other medicines and Clindamycin Capsules

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines:

  • erythromycin (an antibiotic).
  • muscle relaxants used for operations (neuromuscular blockers).
  • oral contraceptive pills. You should use extra contraception such as condoms whilst taking Clindamycin and for seven days after taking Clindamycin.
  • warfarin or similar medicines – used to thin the blood. You may be more likely to have a bleed. Your doctor may need to take regular blood tests to check how well your blood can clot.
  • CYP3A4 or CYP3A5 inducers like rifampicin may impact effectiveness of the medicine.

    Pregnancy and breast-feeding

    Pregnancy

    If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

    Breast-feeding

    Tell your doctor if you will be breast-feeding while taking Clindamycin Capsules as clindamycin may be passed into breast milk. Your doctor will decide if Clindamycin Capsules are appropriate for you. If you continue to take Clindamycin Capsules, you should stop breast-feeding.

Clindamycin Capsules should always be swallowed whole with a full glass of water.

Adults and Elderly Patients

The recommended dose is between 150 and 450 mg (1 to 3 capsules) every 6 hours, depending on the severity of your infection.

Use in children

This medicine is used for children who are able to swallow capsules. The recommended dose in children is between 3 and 6mg per kg of bodyweight every six hours, depending on the severity of the infection. Your doctor will work out the number of capsules that your child should have.

Long term use of Clindamycin Capsules

If you have to take Clindamycin Capsules for a long time, your doctor may arrange regular liver, kidney and blood tests. Do not miss these check-ups with your doctor.

Long term use can also make you more likely to get other infections that do not respond to Clindamycin treatment.

If you take more Clindamycin Capsules than you should

If you accidentally take too many Clindamycin Capsules contact your doctor at once or go to the nearest hospital casualty department. Always take the labelled medicine package with you, whether there are any Clindamycin Capsules left or not. Do not take any more capsules until your doctor tells you to.

If you forget to take Clindamycin Capsules

If the forgotten dose is just a few hours late, use it straight away. If it is nearly time for your next dose miss out the forgotten one. Do not take a double dose to make up for a forgotten dose.

If you stop taking Clindamycin Capsules

If you stop taking the medicine too soon your infection may come back again or get worse. Do not stop taking Clindamycin Capsules unless your doctor tells you to.

If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
