If you took the medication for a few days 2 weeks ago and then stopped, my guess is that the rash is unrelated and could be viral or a different allergy
. Usually allergic reactions will occur during
the first 2 - 3 days of taking a medication. There are exceptions, but that the general time frame.
I hope that helps some.
Feel better. If the rash is itchy, there is a diabetic form of benadryl that you can take.
