Kinds of allergic reaction

Different allergens will cause different kinds of allergic reactions. The most common allergic conditions are hay fever, asthma and skin problems (eg, eczema, rashes, hives).

  • Airborne allergens such as mould, dust, pollen, grasses and weeds can cause hay fever.
  • Pollens, moulds and house dust can trigger asthma attacks.
  • Skin reactions can be caused by contact with an allergen (like latex or certain metals), by insect bites or stings, or by eating food or taking medicine you are allergic to.

Common allergies

Substances that cause allergic reactions are called allergens. The more common allergens include:

  • grass and tree pollen - an allergy to these is known as hay fever (allergic rhinitis)
  • dust mites
  • animal dander (tiny flakes of skin or hair)
  • food - particularly nuts, fruit, shellfish, eggs and cow's milk
  • insect bites and stings
  • medication - including ibuprofen, aspirin, and certain antibiotics
  • latex - used to make some gloves and condoms
  • mould - these can release small particles into the air that you can breathe in
  • household chemicals - including those in detergents and hair dyes

Most of these allergens are generally harmless to people who aren't allergic to them.

If you're allergic to certain types of medicines, there are normally alternatives that can be safely used.

For example, if you're allergic to:

  • penicillin - you can normally safely take a different group of antibiotics known as macrolides
  • non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen and aspirin - you can normally safely take paracetamol; read the ingredients of things like colds medicines carefully to make sure they don't contain NSAIDs
  • one type of general anaesthetic - others are available, or it may be possible to perform surgery using a local anaesthetic or an epidural injection

Always tell any healthcare professional about medicine allergies you have, as they may not be aware of them.
