Understanding Allergies — Your GP's Guide
Allergies happen when the immune system reacts to something harmless, such as pollen, food or pet hair. Reactions range from mild sneezing or itching to severe, life-threatening anaphylaxis.

Comprehensive Allergy Treatment Guide: Navigating Your Options
What are allergies?
The immune system mistakes a substance (allergen) for a threat and releases chemicals like histamine. This produces symptoms such as a rash, swelling, itching, breathing problems or stomach upset.
When to seek medical advice
See a GP for ongoing symptoms or if you suspect a food allergy. Call 999 immediately for swelling of the lips or tongue, breathing difficulty, or sudden collapse.
Available treatments
Antihistamines treat mild reactions. Steroid creams and nasal sprays manage skin and nasal allergies. Adrenaline auto-injectors (EpiPen, Jext) are essential for anyone at risk of anaphylaxis. Immunotherapy may be offered for severe pollen or insect allergies.
What to expect
Most allergies are managed long-term rather than cured. Identifying triggers through allergy testing helps tailor treatment.
Self-care
Avoid known triggers, read food labels carefully, carry your auto-injector at all times if prescribed and tell friends, family and colleagues what to do in an emergency.
How Prescriptsy compares providers
We compare available options using verifiable attributes, not clinical suitability. Only a doctor working for the chosen provider can make that assessment.
We consider indicative price and availability, the consultation and prescription route, and public information about the provider and its licences.
Prescriptsy may receive a fee after a referral. This does not change the user's price or determine the medical information we publish.
Prices, stock and terms can change. Always verify final details with the provider; display order is not medical advice or a treatment recommendation.
