What Substances Commonly Cause Allergic Reactions?
Many substances can cause allergic reactions. Some allergic reactions to insect stings, medicines and a few specific foods, can often be very serious (resulting in a condition called anaphylactic shock) and require immediate medical attention. However, the majority of allergic conditions are not so dangerous but certainly may carry unpleasant symptoms. The most common allergens are:
Grass and Tree Pollens
Certain foods (e.g. wheat, milk, eggs)
Medicines (e.g. penicillin)
Latex (in rubber gloves)
Nickel (in jewellery and metal fastenings)
