I recently was prescribed the sulfa type antibiotic, smz/tmp double str Tb MPC - and with one left to take, started to itch. I noticed small red bumps on the tops of my thighs, the underside of my arms and some on my belly - all of which have been itching.. So, I am using an Aveeno hydro cortisone. The chest cold/crusted eye syndrome I was experiencing for most of the month of Dec 2005..has now died away. It is the day after Christmas and I feel like I've been attacked by a swarm of mosquitoes. I will be sure never to take this again!
