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
• Moulds
• Dust mites
• Animal dander
• Insects
• Certain foods (e.g. wheat, milk, eggs)
• Medicines (e.g. penicillin)
• Latex (in rubber gloves)
• Nickel (in jewellery and metal fastenings)
