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 intestine.
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 injection or during the first several months after your treatment is finished: watery or bloody stools, diarrhea, stomach cramps, or fever.
Talk to your doctor about the risks of receiving clindamycin injection.
Why is this medication prescribed?
Clindamycin injection is used to treat certain types of bacterial infections, including infections of the lungs, skin, blood, bones, joints, 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 viral infections.
How should this medicine be used?
Clindamycin injection comes as a liquid to be injected intravenously (into a vein) over a period of 10 to 40 minutes or intramuscularly (into a muscle). It is usually given two to four times a day.
You may receive clindamycin injection in a hospital, or you may be given the medication to use at home. If you have been told to use clindamycin injection at home, it is very important that you use the medication exactly as directed. Use clindamycin injection at about the same times every day. Follow the directions that you are given carefully, and ask your doctor, pharmacist, or nurse if you have any questions. Do not use more or less of it or use it more often than prescribed by your doctor.
You should begin to feel better during the first few days of treatment with clindamycin injection. If your symptoms do not improve or if they get worse, call your doctor.
Use clindamycin injection until you finish the prescription, even if you feel better. If you stop using clindamycin injection too soon or skip doses, your infection may not be completely treated and the bacteria may become resistant to antibiotics.
Other uses for this medicine
Clindamycin injection is also sometimes used to treat malaria (a serious infection spread by mosquitoes in some parts of the world) and to prevent infection in people who are having certain types of surgery.Clindamycin injection is also sometimes used to treat anthrax (a serious infection that may be spread as part of a bioterror attack) and toxoplasmosis (an infection that may cause serious problems in people who do not have healthy immune systems and in unborn babies whose mothers are infected).
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
