Doxycycline Hyclate and perfect skin

when I was in my early 20's i got a sever case of bad acne! I was prescribed 100mg of Doxy 2 times a day. Of course I learned very quickly to eat before having it. Other than that no side effects. I had flawless skin for about 2 years, at which point i had built up a tolerance to it. When I noticed a few pimples I went straight to my derm before it got out of hand. My derm switched me to minocycline and after about another year of perfect skin I got off of meds all together. I have great skin now, just use proactive and nothing else.

Well now my 14yr old has started breaking out..nothing topical worked, I want to protect her from all of the emotional damage that acne caused for me. Put her on doxy 100mg 2x a day. Shes been on it for about 2 weeks and it seems like the big ones went away but there is an over abundance of small ones now and they are flaring up. Is that normal..I don't remember this happening to me but it was so long ago. Does it get worse before it gets better? Anyone experience this?

I have a pretty severe form of cystic acne which I had a 9-month treatment for when i was 16. It went away completely after a course of accutane up until about 5 months ago when i started smoking cigarettes for the first time. within a few days, i had full blown acne again around my mouth. i'm 23 and its been literally six years of perfect skin i didn't even have to think about. i didn't realize it was the smoking until a month and a half ago. so i stopped, and the acne cut down drastically but not completely, so i went to the dermatologist for medication.

i was given doxycycline, 100mg twice a day. ive been taking it for a month and my skin is back to perfect however I feel like i'm forever feverish, i get extremely nauseated if i don't even enough to eat when i take it, and i get insane hot flashes within 30 mins of taking it. i'm basically sweating nonstop all day long everyday. i want to stop taking it but i don't want the acne to return. i cut down to one pill a day and already see some acne returning. i'm so glad i found this site -- none of the side effects ive seen listed include hot flashes or constant sweating. i also have pretty intense lower back pains
