Clindamycin Dosage: What You Need to Know

If your doctor has prescribed clindamycin, you probably have a lot of questions. It’s a powerful antibiotic used for skin infections, bone infections, and some dental problems. Getting the dose right matters – too little may not clear the infection, too much can cause nasty side effects.

Typical adult dosing

For most adult infections, clindamycin comes in 150 mg, 300 mg, or 450 mg capsules, plus a liquid form for those who can’t swallow pills. The usual schedule is every 6‑8 hours. That means you might take 300 mg three times a day, or 450 mg twice a day, depending on how severe the infection is.

Severe skin or bone infections often need the higher end – 600 mg every 8 hours. Your doctor will adjust the dose based on lab results, how well your kidneys work, and whether you’re taking other meds that could interact.

Kids and special groups

Children don’t get a straight‑up adult dose. Doctors usually calculate the amount by weight – roughly 8‑25 mg per kilogram of body weight per day, split into three doses. A small kid might end up with a 75 mg dose every 8 hours, while a larger teen could be closer to 300 mg.

Elderly patients or people with liver problems may need a lower dose because clindamycin is cleared mainly by the liver. If you have a history of liver disease, your doctor might start you on 150 mg every 8 hours and watch your blood work.

Pregnant or breastfeeding moms should talk to their doctor before starting clindamycin. It’s generally considered safe, but the exact dose may be tweaked to protect the baby.

How to take it right

Take clindamycin with a full glass of water. If you get stomach upset, you can have it with food, but don’t wait a long time after meals – the drug works best when it’s absorbed quickly.

Finish the entire prescription, even if you feel better after a few days. Stopping early can let the bacteria survive and become resistant.

Watch for side effects. Diarrhea is common; if it’s watery and you notice blood or mucus, call your doctor right away. Severe diarrhea could mean C. difficile infection, which needs immediate attention.

Other possible reactions include rash, itching, or liver‑related symptoms like yellow skin or dark urine. Any of these should be reported promptly.

Tips for staying on track

Set a reminder on your phone for each dose. Keep the medication in a place you see every day – on the kitchen counter or next to your toothbrush.

If you miss a dose, take it as soon as you remember unless it’s almost time for the next one. In that case, skip the missed dose and keep your regular schedule – don’t double up.

Store clindamycin at room temperature, away from moisture and heat. Keep it out of reach of children.

That’s the quick rundown on clindamycin dosing. Follow your doctor’s instructions, stay aware of side effects, and you’ll give your infection the best chance to clear up fast.
