The hayfever jab is a corticosteroid injection that helps suppress your immune system’s reaction to pollen. It is administered as a deep intramuscular injection, usually into the buttock. This treatment is only recommended for people with severe symptoms who have tried other remedies without success.
Once administered, the hayfever jab gradually releases the medication into your system over time, reducing inflammation and allergic responses. Most patients notice relief within 48 hours, with some experiencing the full effects within 10 days. The results typically last for up to 3 months, covering the entire hay fever season.
Yes! While the injection provides long-term relief, you can still use antihistamines, nasal sprays, and eye drops if needed.
The hayfever jab is generally safe but may cause mild side effects like soreness at the injection site, headaches, or temporary sleep disturbances. Our GPs will discuss any risks before administering the injection.
For the best results, aim to get your hayfever treatment in March or early April before pollen levels rise.
Most patients only need one dose per season. However, in rare cases, a second dose may be recommended at least 14 days after the first.
