Adverse reactions to medicines include side effects, reactions between
two or more medicines or herbal supplements, reactions between a food and a
medicine, overmedication, and addiction. A reaction can range from mild to severe. Most adverse reactions are not serious.
A drug allergy is a serious type of adverse reaction, because it involves the body's defense system (immune system). It is important for your doctor to find out whether you have a drug allergy or another type of adverse reaction. You have more treatment options if your reaction is not because of an allergy.
