Patient : I use Loestrin 24 as my main form of birth control. However I recently found out I have a sinus infection and started taking azithromycin three days ago. My doctor did not warn me that it could interfere with birth control. Last night I had sex and we did not use a condom. Should I take Plan B just to be safe or does this antibiotic not interfere with my birth control?
