Thanks for using Healthcaremagic,
You are taking many drugs and developed allergy
type rash, it is good that you stopped the drugs.
Potentially any drug can cause rash but Ibuprofen
or cough cold medicine(Dayquil
) is more likely to be cause?
In fact it may not be any drug it could be something in diet or even a insect bite.
If your rash is not troublesome then taking anti allergy medicine will relive itching and rash like Benadryl
If the rash is severe it is better to visit ER where they can examine and give injectable drugs to get prompt relief. In severe cases even short course of corticosteroids
Hope this helps.
