Adults typically take 150 to 450 mg orally every 6 to 8 hours. For children, the dose ranges from 8 to 20 mg/kg/day divided into three or four doses. The duration usually lasts 10 to 14 days, depending on severity.
Oral doses for adults are similar, often 300 mg every 6 hours. Children’s doses are adjusted by weight and infection severity. Intravenous administration may be required for severe cases.
Clindamycin is often prescribed when penicillin isn’t an option. Adults usually take 150 to 300 mg every 6 hours. Children’s doses follow the 8–20 mg/kg/day guideline. Treatment typically lasts 5 to 7 days.
For most infections, adults take 150-450 mg every 6-8 hours. The exact dose depends on the type and severity of the infection. Intravenous dosing can reach 2,700 mg per day in divided doses, especially for serious infections.
Topical clindamycin is used for acne and certain skin infections, applied 2 to 4 times daily as a thin layer. Oral and injectable forms require careful adherence to prescribed schedules for best results.
Children’s doses are weight-based, typically 8 to 20 mg per kilogram of body weight per day, divided into three or four doses. For severe infections, intravenous doses can be higher, up to 40 mg/kg/day.
Topical clindamycin is generally not recommended for children under 12 years old unless specifically prescribed by a doctor.
If you forget to take a dose, take it as soon as you remember. However, if it’s almost time for your next dose, skip the missed one and continue your regular schedule. Never double up doses to make up for a missed one - this can increase the risk of side effects.
Maintaining consistent antibiotic levels in your system is important for effective treatment, so try to take doses at evenly spaced intervals.
Clindamycin is metabolized in the liver, so patients with liver disease may require dose adjustments. Your doctor might reduce the dose or increase the interval between doses to avoid toxicity.
Although the liver primarily processes clindamycin, severe kidney disease may still necessitate monitoring and potential dose changes, especially if combined with other medications.
Taking too much clindamycin can cause serious side effects such as severe diarrhea, abdominal pain, or allergic reactions. If an overdose is suspected, seek emergency medical attention immediately.
Clindamycin can cause Clostridium difficile-associated diarrhea, a potentially life-threatening condition. Notify your healthcare provider if you experience persistent diarrhea, abdominal cramps, or fever during or after treatment.
Take clindamycin with a full glass of water to reduce the risk of irritation.
Complete the full prescribed course, even if symptoms improve early.
Avoid taking clindamycin with dairy products or antacids, muscle relaxants, antifungal medicines, certain anti-seizure medicines, blood thinners and certain vaccines unless directed by your doctor.
Inform your healthcare provider about all medications and supplements you are taking to avoid interactions.
Report any unusual side effects promptly, especially signs of allergic reaction or severe diarrhea.
