Allergic symptoms occur when an immune system treats it incorrectly as a disease-causing substance. The sensitivity of the immune system in general is the same as when the body is exposed to pollen or to some insects or peanuts, for example, to those who are allergic to it.
All medications are prone to side effects. Many of these symptoms occur because of known and expected effects of the drug on the body.
Allergy against drugs is less common and is an unexpected reaction to the immune system.
Penicillin and other antibiotics are among the most common allergens. Drugs administered by injection or by placing on the skin, such as ointments, are more likely to cause these symptoms than oral medications.
