I've been on Erythromycin for 7 days now.
I've had the sore stomach cramps but they've gone. Many people say they come back, but i hope not, they're really painful...
I'm using Differin cream too, it helps dry up the skin.
Erythromycin Bad side effects include
Very dry skin around eyes
Some muscle ache
But I've had good side effects!
Definite reduced redness
Less spots coming through
My problem is acne scars. I can handle the spots but I scar really easily. Hopefully I'll see some progress!!
