Any reason why my doctor put me on one tablet of doxycycline 100 mg for 7 days to treat chlamydia? recommended dose is twice daily. will it clear?

Likely: I'm guessing that they might have made a mistake with the prescriptions, but I would also guess that you will be adequately treated. If you're at all worried, you can go back to clinic or doctor and ask for a test of cure, a repeat chlamydia test, to make sure that the infection is cleared, that's definitely an option. Or call your doctor's office and ask for recommendation as well.

Doxy dose: I am not sure why the dosage of doxycycline was 100 mg once daily. Maybe some miscommunication? At any rate, I think it is a good idea to be retested and to be sure that the chlamydia is gone. Take precautions to protect your partner until that time that you come back negative.

Discuss with doctor: Your doctor must be having reason toper scribe you 100mg daily for 7 days.this dose may clear your chlamydia .

Ask Doc as needed...: That is right twice daily. So, you may ask your Doc for confirming his intent or just overlook now or just wait and see how you may respond to current regimen, and ask him at follow-up and testing for cure. Best wish ...
