Mikesimon gave you the statistics with percentage for rash. I can tell you my personal experience, and what I've heard from others. It seems that people who have trouble with rashes anyway (fair skin) tend to get the worst rashes on Tela. I've never had problems with skin rashes in the past. While on the Tela for the first 8 wks of tx, I developed a rash which was dry, itchy, burning and sandpapery, which began at 6 or 7 wks. It was mostly on trunk and arms and thighs.
