Hi, I've been taking doxycycline hyclate 100mg 1/day for about a month and a half now, and I've had sex before taking the medication. On my last sexual encounter, my labia swelled up quite a lot to the point where penetration wasn't possible due to pain. 2 days later, the swelling went down but there is still itchyness, redness and swelling on what seems to be the bartholin glands. Is this a reported side-effect of doxycycline? Is this normal? What should I do?
