Brand Name: Cleocin
Infrequently, there are severe, rarely fatal, intestinal problems that can occur after use of clindamycin. Consult your doctor right away if you develop persistent diarrhea, stomach pain, or blood or mucus in your stool. These symptoms may occur weeks after stopping use of clindamycin. Do not use antidiarrhea products or narcotic pain medicines if you have these symptoms. These products may make the symptoms worse. Your doctor will monitor you closely while you are using clindamycin.
Clindamycin is used for:
Treating serious infections caused by certain bacteria. It is not used to treat meningitis.
Clindamycin is a lincomycin antibiotic. Clindamycin kills sensitive bacteria by stopping the production of essential proteins needed by the bacteria to survive.
Do NOT use clindamycin if:
- you are allergic to any ingredient in clindamycin or to lincomycin
- you have certain intestinal problems (eg, antibiotic-associated colitis, Crohn disease, ulcerative colitis) or meningitis
Contact your doctor or health care provider right away if any of these apply to you.
Before using clindamycin:
Some medical conditions may interact with clindamycin. Tell your doctor or pharmacist if you have any medical conditions, especially if any of the following apply to you:
- if you are pregnant, planning to become pregnant, or are breast-feeding
- if you are taking any prescription or nonprescription medicine, herbal preparation, or dietary supplement
- if you have allergies to medicines, foods, or other substances
- if you have diarrhea, or a history of liver problems or stomach or bowel problems (eg, colitis)
- if you are allergic to tartrazine
Some MEDICINES MAY INTERACT with clindamycin. Tell your health care provider if you are taking any other medicines, especially any of the following:
- Nondepolarizing muscle relaxants (eg, vecuronium) or succinylcholine because the risk of their side effects may be increased by clindamycin
- Erythromycin because it may decrease clindamycin's effectiveness
This may not be a complete list of all interactions that may occur. Ask your health care provider if clindamycin may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.
How to use clindamycin:
Use clindamycin as directed by your doctor. Check the label on the medicine for exact dosing instructions.
- Take clindamycin by mouth with or without food.
- Take clindamycin with a full glass of water (8 oz/240 mL).
- Clindamycin works best if it is taken at the same time each day.
- To clear up your infection completely, take clindamycin for the full course of treatment. Keep taking it even if you feel better in a few days.
- If you miss a dose of clindamycin, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.
Ask your health care provider any questions you may have about how to use clindamycin.
Important safety information:
- Clindamycin only works against bacteria; it does not treat viral infections (eg, the common cold).
- Be sure to use clindamycin for the full course of treatment. If you do not, the medicine may not clear up your infection completely. The bacteria could also become less sensitive to this or other medicines. This could make the infection harder to treat in the future.
- Long-term or repeated use of clindamycin may cause a second infection. Tell your doctor if signs of a second infection occur. Your medicine may need to be changed to treat this.
- This product may contain tartrazine dye (FD&C Yellow No. 5). This may cause an allergic reaction in some patients. If you have ever had an allergic reaction to tartrazine, ask your pharmacist if your product has tartrazine in it.
- Mild diarrhea is common with antibiotic use. However, a more serious form of diarrhea (pseudomembranous colitis) may rarely occur. This may develop while you use the antibiotic or within several months after you stop using it. Contact your doctor right away if stomach pain or cramps, severe diarrhea, or bloody stools occur. Do not treat diarrhea without first checking with your doctor.
- Lab tests, including liver function, kidney function, and complete blood cell counts, may be performed while you use clindamycin. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
- Use clindamycin with caution in the ELDERLY; they may be more sensitive to its effects, especially diarrhea.
- Use clindamycin with extreme caution in CHILDREN younger than 10 years old who have diarrhea or an infection of the stomach or bowel.
