"i started doxycycline for acne on october 7th 2015. my acne was not terrible but my chin was constantly breaking out and i was tired of it. second week into doxy my face got worse! i was so very upset and even considered stopping the medication. do not stop! for me it got worse before it got better. stick with it. today - november 24th 2015 my skin is almost completely clear. i do understand that this medication may not work for everyone. i do feel a little bit more constipated than usual. also- make sure you take this medication with food. i hope this forum helped!"
