Common brand name: Cleocin
Description: Clindamycin is a broad-spectrum antibiotic. It works particularly well against certain types of bacteria.
Dental uses: This drug has three main uses in dentistry.
First, it is used in people who are allergic to penicillins and at risk to develop bacterial endocarditis. This is a serious heart infection. It can be fatal. People at risk for this infection take antibiotics before dental treatments that tend to cause bleeding. People at risk include those who have:
Artificial heart valves
A history of endocarditis
Certain forms of congenital heart disease
A transplanted heart that develops valve disease
Bleeding can occur in treatments that:
Puncture or cut into mouth tissue
Manipulate the gums or the area around a tooth root
Clindamycin is used in place of amoxicillin in at-risk patients who are allergic to penicillin and related drugs.
Second, clindamycin is used to help prevent joint infections in people who have had total joint replacement surgery.
Third, it is prescribed for people with dental abscesses in bone and soft tissue that don't respond well to penicillin VK. Oral surgeons and endodontists often prescribe it for long-lasting infections in bone.
Dosages for dental purposes: To prevent bacterial endocarditis or joint infection, the dose is 600 milligrams (4 tablets of 150 milligrams each). It should be taken 30 to 60 minutes before a dental treatment likely to cause bleeding. Patients generally tolerate the one-dose regimen well. For oral infections or abscesses, the dose is 150 milligrams to 300 milligrams every 6 to 8 hours. It should be taken for at least 5 to 7 days.
As with all medicines, be sure to follow your doctor's prescription. Take clindamycin for the prescribed length of time, even if you start to feel better. Do not stop taking it without talking to your doctor. Stopping an antibiotic too soon may cause bacteria to become resistant to antibiotics. This means the antibiotics won't work the next time.
Concerns and possible side effects: Tell your dentist and physician about all the medicines you take. This should include over-the-counter vitamins and herbal supplements. Also, let your dentist know if you have had a sensitive or allergic reaction to any medicine. If you are pregnant or nursing, or might be pregnant, talk to your primary care doctor before starting any new medicine. This also includes vitamins and supplements.
Diarrhea and abdominal pain are more common with clindamycin than with penicillin VK. Occasionally, people treated with clindamycin or other antibiotics develop a severe form of bloody, mucus-filled diarrhea. This is known as pseudomembranous colitis. It can occur during or after antibiotic treatment. It is caused by excess growth of Clostridium difficile bacteria in the intestines. These bacteria are resistant to clindamycin.
This type of diarrhea is not common with the dental use of clindamycin. However, it occurs more often in people who are elderly, have a history of colitis, or take clindamycin for a long time. Treatment often begins with stopping the antibiotic you were taking. You will be given a different antibiotic.
The clindamycin label contains a "black box" warning. It says that this drug can cause severe and possibly fatal colitis. If you have diarrhea while taking clindamycin or up to several months afterward, contact your dentist or physician right away.
Tell your doctor about any reaction to a prescribed medicine, no matter how minor it might be.
