urticaria
"I've been on Periactin for about 6 months. I take 8mg at night but I can't get up on time in the morning and the kids are late for school most days. I have found it works for my chronic urticaria but also noticed a huge weight gain. I was watching myself get fatter but didn't know why. After reading all the other reviews I now know it is the Periactin so I'm thinking of cutting back on the tablets. I need to lose weight. I feel horrible."
