 [ Symptoms ] bad acne problem recently within the past month i started breaking out i quit smoking and notice it got worse i had stopped working out but started again break outs are on my cheeks and left and right side of my forehead i went to the doctor and they prescribed me doxycycline which does not seem to be working i have been on it for a week i am taking 100mg 2 tablets a day my doctor gave me a 10 day prescription also using proactive plus and that does not even seem to be helping i really some help [ Disease ] i really have no way of blindly treating your acne over the internet there are several types of acne and i also cannot determine the severity based solely on the information in your posting it can take several weeks    not one week    to see results from oral doxycycline so your doctor may need to extend your prescription beyond the ten days this will not help certain types of acne so again i have no way of knowing if this is an appropriate approach there are dozens of different acne medications available by prescription seeing a dermatologist should be considered if you are not improving on your doctor is current regime
