hi my daughter has recently been having acne breakouts she is 35 yrs old 3 kids, and is president of little league in our small town. im sure stress plays a big role in her recent flair ups but she has gone to a dermatoligist and he has put her on seldane after reading a little bit about the medicine it keeps mentioning that in 1998 the medication was taken off the market, are you familiar with this medication?
