Claire Billes - Drug allergy is one of the most unpleasant forms of allergy as you cannot be sure whether you have it or no. Even though quite often a person suffers from several types of allergy (ex. pollen, food, dust or cats/dogs allergies), it doesn’t mean that situation is the same in all cases.
A person who suffers from one allergy type may be allergic to particular drugs or no. At the same time a person who has never been discovered any type of allergy can develop a reaction to drugs.
