Hello! I used to come on this board all the time. So desperate to fix my skin. I took Spiro for 7 years. I had so many side effects and just felt awful. At a high dose my skin was perfect but I felt terrible. At a lower dose I felt better but my skin would break out still. I couldn't win. A year ago I started working for a dermatologist. He does not perscribe Sprio EVER. Spiro is a bandaid. Accutane is the cure....
I've had back acne(cyst, I think it's rosacea) for more than 10 years. and I'm a little bit fat, 85kg. So Maybe 20mg every other day isn't strong enough for me? Can I try 30mg or 40mg every other day(or every day) for half a year(or a whole year)? and then can I take 30mg or 40mg every week for long term use? What's the side effect if I take it overdose for long term(like forever)?
And would you please ask your derm if the low dose doxycycline (40mg per day) works or not? I think it's a permanent solution for acne or rosacea. Here's a link about it: http://www.acne.org/...sounds-perfect/
No your weight does not matter. I would never recommend taking more than 20mg. You may need a longer course but it's better to take it longer than to take it in a higher dose. You could do 20mg every day for 5 months and then drop to every other day. Then maybe twice a week, and then down to 1 x a week. And see if you stay clear. But this is something that your Dr would have to monitor. We wouldn't stop someone until they were clear. Some people need longer courses. I dunno about taking it forever. I don't think that is needed.
There are alot of possible side effects. It can effect your liver, your stomach, raise cholesterol ect. So serious stuff.
I would never recommend any antibiotic for acne or rosacea. They don't work. We all have bacteria all over us. Antibiotics kill the bacteria temporarily unitl the bacteria outsmarts the antibioic and build resistance to it. Oil is the problem. Not the bacteria. Acne is an inflammatory disease caused by too much oil. You must control the oil.
