Doxycycline
"Doxycycline for acne works wonders! I will say if your acne has gotten really bad and you just started on doxycycline you will need to be patient with this drug and give it time to work its magic. I highly recommend taking it with food or else you will throw up as I did. Taking it on a normal schedule I have seen does improve the use of the drug for example taking it everyday in the morning or night around the same time is good! Remember everybody's body responds differently to medication. But, if I were to just start looking into acne medicine I would start on this. Not too strong as Accutane, but not too weak either. I had moderate to severe cystic acne twice and it has been able to clear both incidents. Never had bad side effects on this"
