With wasp numbers at record highs in the UK, understanding sting allergies is more important than ever. This guide explains how to recognise serious reactions, the steps to diagnosis, and why Venom Immunotherapy (VIT) is considered the gold standard treatment for long-term protection against severe sting allergies.

Are you unsure about the best way to bathe babies with eczema? Should bathing be frequent or occasional? Is anything needed in the water, and does the temperature make a difference? Should the skin be patted dry rather than rubbed? Does water hardness play a role? And what if the skin looks infected—does that change things? These are some of the most common questions we hear in our clinic.

• Explore Neffy nasal spray, the innovative needle-free adrenaline device for anaphylaxis.

• Discover its UK availability, benefits, usage guidance, and expert insights.

Xolair is used to reduce the frequency and severity of allergic reactions, including life-threatening anaphylaxis, that can result from accidental ingestion of a food allergen. We use it in clinic for various indications including i) to facilitate OIT to multiple foods and in very sensitive indiduals, ii) to cover high-risk activities, travelling through certain countries where food allergens may be plentiful and lablling less obvious, or just for ongoing use and protection.

At our London Allergy Centre of Excellence, we provide Oral Immunotherapy (OIT) to help patients with food allergies such as peanut, nut, sesame, milk, and egg. This structured treatment builds tolerance under medical supervision, offering long-term protection and reducing the risk of severe allergic reactions.
