AntibioticsLincosamidesInfectious Disease

Drug Class

Lincosamide Antibiotic

Pregnancy

Category B — Animal reproduction studies have not demonstrated fetal harm. There are no adequate, well-controlled studies in pregnant women, but observational data have not shown an increased rate of birth defects. Clindamycin is generally considered acceptable during pregnancy when needed for serious infections.

Available Forms

Oral capsule (75 mg, 150 mg, 300 mg), Oral solution (75 mg/5 mL), Topical solution, gel, lotion, or foam (1%), Vaginal cream (2%), Vaginal suppository (100 mg), IV/IM injection (150 mg/mL)

What It's Used For

is prescribed to treat:

• Bacterial infections, especially skin and dental infections • Various related conditions in the antibiotics category • Associated symptoms and complications

It is an important medication that helps manage these conditions effectively.

Dosage Quick Reference

These are general dosage guidelines. Your doctor will determine the appropriate dose for your specific situation.

ConditionStarting DoseMaintenance Dose
Skin and soft tissue infection (MSSA/MRSA)300–450 mg orally every 6 hoursContinue for 5–10 days based on clinical response
Dental infection / odontogenic abscess300 mg orally every 6 hoursContinue for 5–7 days
Bacterial vaginosis (intravaginal)One applicator (5 g) at bedtimeContinue for 7 nights
Severe infection (IV)600–900 mg IV every 8 hoursTransition to oral when clinically appropriate
Acne vulgaris (topical)Apply thin film twice dailyUse long-term, often combined with benzoyl peroxide
Endocarditis prophylaxis (penicillin-allergic)600 mg orally 30–60 minutes before procedureSingle dose

Side Effects

Common side effects may include:

Nausea or stomach upset • Headache • Dizziness or lightheadedness • Fatigue or tiredness • Mild rash or itching

Serious side effects (seek immediate medical attention):

• Severe allergic reactions (rash, hives, swelling, difficulty breathing) • Unusual bleeding or bruising • Severe stomach pain • Signs of liver problems (yellowing of skin/eyes, dark urine) • Chest pain or irregular heartbeat • Severe dizziness or fainting • Signs of serious adverse effects

Drug Interactions

Clindamycin has a relatively focused interaction profile, though it carries a notable boxed warning for Clostridioides difficile colitis that influences how it is co-prescribed.

  • Neuromuscular blocking agents (e.g., succinylcholine, vecuronium): Clindamycin can enhance the action of neuromuscular blockers, prolonging respiratory depression. Use caution during anesthesia and inform the surgical team.
  • Erythromycin and other macrolides: Antagonistic at the bacterial ribosome through competition at the same binding site. Avoid concurrent use, as it may diminish the effect of either antibiotic.
  • CYP3A4 inhibitors (e.g., ketoconazole, ritonavir): May increase clindamycin plasma concentrations, though clinical significance is usually modest. Monitor for adverse effects.
  • CYP3A4 inducers (e.g., rifampin, phenytoin): May decrease clindamycin levels, potentially reducing antibiotic efficacy. Consider alternative antibiotics or close clinical monitoring.
  • Other agents associated with C. difficile risk (e.g., proton pump inhibitors): Concurrent use may compound the risk of antibiotic-associated diarrhea and pseudomembranous colitis. Use the shortest effective antibiotic course.

Frequently Asked Questions

Clindamycin disrupts the normal balance of bacteria in the colon, allowing Clostridioides difficile to overgrow and produce toxins that cause severe diarrhea and colitis. While many antibiotics carry this risk, clindamycin is among the highest-risk agents. Report any persistent or watery diarrhea — especially after the antibiotic course ends — to your doctor immediately.
Yes. Clindamycin can be taken with or without food, though taking it with a full glass of water is recommended to prevent throat irritation. Some patients find that taking it with food helps reduce nausea, which is a common side effect.
Yes. Clindamycin is a lincosamide and is structurally unrelated to penicillins or cephalosporins. It is commonly used as an alternative for skin, soft tissue, and dental infections in patients with severe penicillin allergy, including those with documented anaphylaxis.
Combination therapy reduces the risk of antibiotic resistance — a growing concern with topical clindamycin used alone. Benzoyl peroxide kills bacteria through a non-antibiotic mechanism and helps prevent resistant strains from developing. Many products combine the two ingredients in a single formulation for convenience.
Most patients notice improvement in redness, swelling, and pain within 48 to 72 hours of starting therapy. Complete the full prescribed course — typically 5 to 10 days — even if symptoms resolve early, to prevent relapse and resistance. Contact your doctor if symptoms worsen or fail to improve after 3 days.

Questions to Ask Your Doctor

Consider discussing these topics at your next appointment:

  • What signs of C. difficile infection should make me call you, even after I finish the course?
  • Is there a narrower-spectrum antibiotic that might work for my specific infection?
  • Should I take a probiotic while on clindamycin, and if so, which one?
  • How will we know if the infection is responding, and when should I follow up?
