Are You Truly Allergic to That Medication?
A drug allergy occurs when your immune system mistakenly identifies a drug as a harmful substance, similar to how it attacks invading viruses or bacteria. When your immune system fights back, a series of chemical steps in the body produce an allergic reaction to the medication. The first time you take a medication, you may have no complications. However if your immune system is sensitive to the medication, it will produce antibodies.
