How To Cure Red Itchy Rashes On Chest And Back After Taking Mucinex DM?

I took Mucinex DM twice a day for two or three days earlier this week. For the past 3 days I have had a red rash that itches violently on my chest, lower back and thighs. Have used benadryl gel and have taken a benadryl at night ever since it started. I need to know what to do. I can't stand the itch and its starting to scare me.

Hi,

It seems that you might have developed drug rash. As there is itchy rash after taking mucinex DM. You take steroid in tappering dose for two weeks. And you take antihistaminics like levocetirizine till itch is relieved. Apply mild steroid cream on the skin lesions. Avoid soap during bath. You may be improved. I hope you got my answer.

Thanks.
