As with other allergic reactions, these symptoms can occur when your body’s immune system becomes sensitized to a substance in the medication, perceives it as a foreign invader and releases chemicals to defend against it.

People with drug allergies may experience symptoms regardless of whether their medicine comes in liquid, pill or injectable form. If you feel confused about your symptoms and which medications are safe for you to take then it’s time to take control and see an allergist.
