Antibiotic therapy (topical or oral) is commonly used to treat acne in many patients and is usually considered to be safe and effective. The mechanism by which these antibiotics for acne work differs with the drug. Some antibiotics have antibacterial properties with minimal anti-inflammatory effect, while some have both anti-inflammatory and antibacterial properties. Macrolides like clindamycin, erythromycin and azithromycin have minimal anti-inflammatory properties and work mainly by reducing P.acne level, while other antibiotics like tetracycline and its derivatives has both potent anti-inflammatory and antibacterial properties.
Topical Antibiotics for Acne
Topical antibiotics are generally used to treat mild cases of acne. They are safer and accurate to use as compared to other oral antibiotics. These topical antibiotics are either used a single line regimen or with combination therapy, but are more effective when used in combination with other topical preparations like Benzoyl peroxide or retinoids.

Candidates for oral antibiotics therapy includes:
- Patients with moderate to severe inflammatory acne
- Patients who have failed response to topical therapy
- Patients whose acne covers a large area, thus making topical therapy impractical
