There were some side effects from doxycycline hyclate 100mg dosage
. The first day I felt drowsiness and pain in the muscles. I have treated chlamydia, and take the drug two times a day. On the second day, everything is much better. In my opinion, despite the side effects, the main task for me is to be cured of chlamydia, and I will pursue this goal. It seems to be an effect.
