Many antibiotics, including clindamycin, may cause overgrowth of dangerous bacteria in the large intestine. This may cause mild diarrhea or may cause a life-threatening condition called colitis (inflammation of the large intestine). Clindamycin is more likely to cause this type of infection than many other antibiotics, so it should only be used to treat serious infections that cannot be treated by other antibiotics. Tell your doctor if you have or have ever had colitis or other conditions that affect your stomach or intestines.
You may develop these problems during your treatment or up to several months after your treatment has ended. Call your doctor if you experience any of the following symptoms during your treatment with clindamycin or during the first several months after your treatment has finished: watery or bloody stools, diarrhea, stomach cramps, or fever.
Talk to your doctor about the risks of taking clindamycin.
Clindamycin is used to treat certain types of bacterial infections, including infections of the lungs, skin, blood, female reproductive organs, and internal organs. Clindamycin is in a class of medications called lincomycin antibiotics. It works by slowing or stopping the growth of bacteria. Antibiotics such as clindamycin will not kill the viruses that cause colds, flu, and other infections.
Clindamycin comes as a capsule and a solution (liquid) to take by mouth. It is usually taken three to four times a day. The length of your treatment depends on the type of infection you have. Take clindamycin at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take clindamycin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Shake the liquid well before each use to mix the medication evenly.
Take the capsules with a full glass of water so that the medication will not irritate your throat.
You should begin to feel better during the first few days of treatment with clindamycin. If your symptoms do not improve or if they get worse, call your doctor.
Take clindamycin until you finish the prescription, even if you feel better. If you stop taking clindamycin too soon or skip doses, your infection may not be completely treated and the bacteria may become resistant to antibiotics.
Clindamycin is also sometimes used to treat acne and is used along with other medications to treat anthrax (a serious infection that may be deliberately spread as part of a terror attack) and malaria (a serious infection that is spread by mosquitoes in certain parts of the world). Clindamycin is also sometimes used to treat ear infections and toxoplasmosis (an infection that may cause serious problems in people who do not have healthy immune systems or in unborn babies whose mothers are infected) when these conditions cannot be treated with other medications. Clindamycin is also sometimes used to prevent endocarditis (infection of the heart valves) in certain people who are at risk of developing this infection as a result of a dental procedure. Talk to your doctor about the risks of using this medication for your condition.
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
