How Do I Know If I Am Allergic To Medication?

Basically, anything you experience which is "different" to normal after beginning a new medication can be an allergic reaction. Skin rashes are the most common allergic reaction to medication, but some reactions can be as severe as to lead to difficulty breathing.

If you experience any symptoms that worry you after beginning new medication or even if you begin to experience something different with an established medication - talk to your doctor immediately.
