How does this medication work? What will it do for me?
Clindamycin belongs to the class of medications called antibiotics. It is used to treat infections caused by certain types of bacteria. It is also used before dental procedures or surgery to prevent infections for people who have heart conditions that put them at greater risk of infection. Clindamycin kills bacteria by preventing the growth of the bacteria, so they cannot reproduce.

How should I use this medication?
The recommended adult dose of clindamycin is 150 mg to 450 mg every 6 hours, swallowed whole, with a full glass of water.
The dose of clindamycin for children is based on body weight. The recommended dose is 2 mg to 5 mg per kilogram of body weight taken every 6 hours.
Prior to surgery or dental procedures, the recommended adult dose is 300 mg taken 1 hour before the procedure and 150 mg 6 hours after the first dose. The recommended dose for children is 10 mg per kilogram of body weight 1 hour before the procedure and 5 mg per kilogram of body weight 6 hours after the first dose. The dose should not be more than the adult dose.
When given intravenously (into a vein), the recommended dose is 600 mg to 900 mg every 6 to 8 hours.
If you have been prescribed the suspension (liquid) form of clindamycin, use an oral syringe to measure each dose, as it gives a more accurate measurement than household teaspoons.
Although you can take clindamycin with food or on an empty stomach, it may cause less stomach upset if taken with food.

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Antibiotic-related diarrhea: As with other antibiotics, clindamycin can cause a severe form of diarrhea associated with a condition known as pseudomembranous colitis. If you develop severe diarrhea while taking (or within a few weeks of taking) this medication, contact your doctor as soon as possible.
Bacterial resistance: Misuse of an antibiotic such as clindamycin may lead to the growth of resistant bacteria that will not be killed by the antibiotic. If this happens, the antibiotic may not work for you in the future. Although you may begin to feel better early in your course of treatment with clindamycin, you need to take the full course exactly as directed to finish ridding your body of the infection and to prevent resistant bacteria from taking hold. Do not take clindamycin or other antibiotics to treat a viral infection such as the common cold; antibiotics do not kill viruses, and using them to treat viral infections can lead to the growth of resistant bacteria.
Kidney problems: Clindamycin may cause damage to the kidneys. If you experience symptoms of decreased kidney function, such as a decrease in the amount you are urinating; swelling in your hands, feet, or ankles; difficulty breathing; or unusual tiredness, let your doctor know as soon as possible.
Liver disease: Liver disease or reduced liver function may cause this medication to build up in the body, causing side effects. If you have liver problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Overgrowth of organisms: The use of antibiotics occasionally results in the overgrowth of organisms that the antibiotics don’t kill, such as other bacteria or fungi and organisms. This can cause other infections, such as yeast infections, to develop. If you experience new symptoms while taking clindamycin, contact your doctor.
Gastrointestinal problems: Severe diarrhea associated with this antibiotic may be mistaken for symptoms of chronic gastrointestinal conditions. If you have colitis, inflammatory bowel disease, or Crohn’s disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Pregnancy: The safety of this medication for use during pregnancy has not been established. This medication should not be used unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: This medication passes into breast milk. If you are breast-feeding and are taking clindamycin, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Seniors: Seniors may be more likely to experience antibiotic-related diarrhea associated with clindamycin.
