"i took this medication smz/tmp for acne/scars on my face.  i had a very severe allergic reaction. my face was swollen and lips. my hands swelled up. i had terrible pains in my wrists up to my arms and pain in my stomach/abdomen.  this happened after taking it for around a week. my dad had to drive  me to the emergency room because i couldn&#039;t swallow and was almost choking. i was so scared. i warn anyone going on this medication to think twice. i had no idea i would have an anaphylaxis reaction to it. very serious. it was hell going through this and i really thought i would die. i didn&#039;t know what was happening to me as i was choking in my sleep. my mom looked up the side effects and that&#039;s when we found out it was a terrible reaction."
