"i started using this product when i was about 15 and used it for almost a year.  this medication made my skin extremely sensitive to sun. if i did not take this medication with food, i would feel like i was going to throw up.  doxycycline was effective for controlling my acne, but the side effects did not make it a realistic choice.  
i have switched to using birth control pills for controlling my acne.  i have found that they are equally as effective as doxycycline, and i am no longer as prone to sunburns.  i also do not suffer from nausea from birth control.   
overall, i have found birth control pills to be more compatible for my body, more useful (in their many purposes), and more convenient."
