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.
For best results, we recommend booking your hay fever injection in March or early April, before pollen levels rise sharply.
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.
The injection is given intramuscularly into the buttock for best absorption and minimal discomfort.
