Treating your allergy

Visiting the doctor for allergy treatment advice

Antihistamines / Decongestants / Glucocorticosteriods / Immunotherapy

If you begin experiencing allergy symptoms for the first time, it's important to see a doctor before taking further action. As well as a diagnosis, a doctor can also offer advice on hay fever. Alternatively you could visit a pharmacist who would be able to offer you advice on suitable treatment options.

Once you have decided that allergy medication should be part of the fight against your allergies, you then have the challenge of deciding which type of allergy medication is the best choice.

Start by finding out what kind of treatment is available, and how each of them works to relieve your symptoms:


Antihistamines are the most common form of hay fever medication, which work by blocking the action of histamine in your system. They come in pill, liquid and nasal spray form, over the counter or by prescription.

Antihistamines help relieve your most common allergy symptoms, including itchy or watery eyes, sneezing and runny noses among others.
