Your doctor will usually review you after 4 to 6 weeks to check how well the medicine is working. If you are taking doxycycline for any other infection, tell your doctor if you don’t start feeling better after 3 days. Also tell them if, at any time, you start to feel worse.
If you are diagnosed with chlamydia, your doctor will prescribe oral antibiotics. A single dose of azithromycin or taking doxycycline twice daily for 7 to 14 days are the most common treatments and are the same for those with or without HIV. With treatment, the infection should clear up in about a week.Jan 16, 2020
