Allergic reactions happen when your body is sensitive to a specific substance. The reaction can happen when you swallow or inhale the substance or when it is applied to your skin or injected or transfused through an IV into your body.

In most cases, these negative effects take the form of mild, bothersome, but ultimately short-term, side effects. For instance, a common side effect of taking antibiotics is stomach upset and/or diarrhea. A common side effect of taking pain medicine is constipation.
