Dayquil allergy?

Does anyone have any allergies to cold medications such as Dayquil? I don't know if it's a coincidence or not, but last year I had bronchitis and took Dayquil, I had an all over body rash but the doc said it was due to my virus. This I got sick again a couple days ago and tried Dayquil and once again, I got an all over body rash. Doc said it was the virus again - but it just seemed odd that I broke out in a rash twice while using Dayquil.

Thanks Carla, it just seems to be an odd sort of allergy if you know what I mean.
