What are the signs of a allergic response?

I have started taking "cranberry" vitamins 2 times a time & i have broken out into a imprudent & have have really bad nausea.
I own drank "cranberry juice" before & own had no impulse to it so i am not sure if i am allergic to the "cranberry" pills.
I also take iron pills,multi vitamin & flaxseed grease vitamins everyday.
Could something i have taken take action with the "cranberry" pills?What are the signs of a allergic response?
ya i would stop taking them and if your over-hasty goes away next there ya budge. if not consequently maybe attain checked out in a few days or if it get worse
bumps on skin rash,maw blistering or other parts of the body
A rash, sneezing, not human being able to breath etc. Sounds similar to you may be having a counterattack so stop taking them and see if you get better.
