May 2024 Archive: Understanding Clindamycin

This month we covered clindamycin — a commonly prescribed antibiotic for many bacterial infections. The goal was simple: explain how it works, when it helps, and what to watch for so you can use it safely. If you got a prescription or are curious about this drug, this summary gives the practical points you need.

How clindamycin works and when it's used

Clindamycin stops certain bacteria from making proteins they need to grow. Doctors often prescribe it for skin infections, dental abscesses, some lung infections, and certain bone or pelvic infections. It comes as pills, liquids, and topical gels or creams. Which form you get depends on the infection and how severe it is.

For example, oral clindamycin is common after dental surgery or for deeper skin infections. Topical clindamycin is used for acne. Your doctor will choose the right form and length of treatment based on the infection and your health history.

Practical dosing and administration tips

Follow the prescription exactly. Typical adult oral doses vary but often range from 150–450 mg every 6–8 hours depending on the infection. Don’t skip doses and finish the full course even if you feel better early — stopping too soon can let the infection return and promote resistance.

To reduce stomach upset, take clindamycin with a full glass of water and consider taking it with food. If you use the liquid form, shake well and measure carefully. Apply topical forms to clean, dry skin as directed and avoid contact with eyes or mouth.

Watch for side effects. The most common are nausea, diarrhea, and stomach pain. A more serious risk is Clostridioides difficile (C. difficile) infection, which causes severe, persistent diarrhea and needs urgent care. Call your doctor if diarrhea is severe or you pass blood in your stool.

Allergic reactions are rare but possible. If you notice rash, swelling, trouble breathing, or dizziness, stop the medicine and seek emergency care. Tell your provider about any other medicines you take — clindamycin can interact with drugs that affect breathing or with certain antibiotics.

Special situations: pregnant or breastfeeding? Talk to your doctor. They will weigh the benefits and risks. For children, dosing is weight-based, so never guess the dose — use the doctor’s instructions and measuring device provided with the medicine.

Store pills and liquids at room temperature, away from direct heat and moisture. Dispose of leftover medication safely. If you miss a dose, take it as soon as you remember but skip it if it’s almost time for the next dose — don’t double up.
