Clindamycin: What it treats and how to use it

Clindamycin is a common antibiotic you’ll hear about for skin infections, some dental infections, and certain lung or bone infections. It comes as pills, topical gels, and injections. It works well when chosen for the right bug, but it also has a higher chance than many antibiotics to cause serious diarrhea. That trade-off matters—so you should know when to use it and when to call your doctor.

When and how it's used

Doctors often prescribe oral clindamycin for skin and soft tissue infections (like cellulitis), dental abscesses, and when other antibiotics aren’t suitable. Topical clindamycin is widely used for acne to reduce bacteria and inflammation. IV clindamycin is reserved for more serious hospital-treated infections. If you get a prescription, follow the exact dose and finish the full course even if you feel better early. Stopping early can let the infection come back or fuel resistance.

How to take it: read the label and follow your prescriber. Many people take the oral capsules with a glass of water and some food if stomach upset occurs. For topical use, apply to clean, dry skin in a thin layer and avoid getting it in your eyes. If you miss a dose, take it as soon as you remember unless it’s almost time for the next dose—don’t double up.

Safety, side effects, and buying tips

Common side effects include nausea, stomach pain, and yeast infections. The big concern is Clostridioides difficile (C. difficile) infection: severe, watery diarrhea that can be dangerous. If you develop persistent diarrhea, fever, or bloody stools, stop the antibiotic and get medical help right away. Also watch for allergic reactions—hives, swelling, or trouble breathing—seek emergency care if that happens.

Tell your doctor about liver disease, bowel disease (like colitis), and any other medicines you take. That helps them avoid harmful combos. If you’re pregnant or breastfeeding, ask your doctor—clindamycin is used in some situations but only when it’s the right choice for you.

Thinking of buying clindamycin online? Use only licensed pharmacies that require a prescription and offer pharmacist contact. Check reviews and avoid sites that sell antibiotics without a prescription. A safe online pharmacy will show clear contact info, pharmacist support, and verified payment methods.

Storage is simple: keep tablets and topical products in their original container at room temperature and out of reach of kids. Dispose of any leftover antibiotic safely—don’t keep it for the next illness.

Bottom line: clindamycin helps many infections but needs careful use because of side effects and C. difficile risk. Follow your prescriber, watch for warning signs, and use reputable sources if you buy medicine online.
