Clindamycin phosphate topical solution usp?

Clindamycin phosphate topical solution, USP is a prescription topical antibiotic used for acne vulgaris. Key points:

- Active ingredient: clindamycin phosphate, typically 1% w/v (about 0.8–1% clindamycin equivalent depending on the salt form). It's a prodrug that delivers clindamycin locally.
- Indication: treatment of moderately to moderately severe acne vulgaris in patients 12 years and older (usually applied to affected areas).
- How to use: apply a thin layer to clean, dry skin on the affected areas twice daily (morning and night). Avoid eyes, lips, mouth, and mucous membranes. Wash hands after applying.
- Interactions with other products: may be used with benzoyl peroxide; if using both, apply at different times or allow products to dry between applications to reduce irritation.
- Side effects: common are local skin reactions such as dryness, burning, redness, or itching. Less commonly, irritation or peeling. Serious adverse events are rare with topical use; discontinue and seek care if you develop severe rash or signs of an allergic reaction.
- Precautions: not for broken skin, avoid contact with eyes/mucous membranes, may cause contact dermatitis in sensitive individuals. Systemic antibiotic–associated colitis is rare but possible; seek medical attention if you develop severe or persistent diarrhea.
- Storage: room temperature, keep lid closed, protect from excessive heat and moisture.
