Drug Allergy

 Drug allergies are a set of symptoms caused by an allergic reaction to a drug. A drug allergy encompasses an immune response in the body that develops an allergic reaction to a medicine. If you may develop a rash, hives or difficulty breathing after taking certain medications, you may have a drug allergy. As with other allergic reactions, these symptoms of drug allergy can occur when your body’s immune system becomes sensitive to a substance in the medication, identifies it as a foreign invader and releases chemicals to defend against it.
