What is the Best Antibiotic for Chlamydia?

Linda Girgis | MD

Medically reviewed by Linda Girgis | MD, Girgis Family Medicine on August 21st, 2026.

Doctronic recommends azithromycin (Zithromax) as the best first-line antibiotic for uncomplicated chlamydia infections. Our AI medical consultations can help you get proper testing and treatment recommendations. Azithromycin is preferred because it's a single 1-gram oral dose with a 95% cure rate, making it highly effective and convenient. Alternative options include doxycycline (100mg twice daily for 7 days) or erythromycin for pregnant patients. Both partners need treatment simultaneously to prevent reinfection. You can consult with our AI doctor about symptoms and get guidance on testing locations, or speak with providers on Teladoc, K Health, Amwell, or PlushCare for prescription services.
