✅ Quick Answer: How Long Does the Hayfever Injection Last?

The Kenalog hayfever injection typically lasts 6–8 weeks, covering most of the UK’s peak pollen season.

Some patients feel relief within 24–48 hours, with effects lasting up to 10 weeks depending on individual response and environmental exposure.

⏳ What Affects How Long It Works?

Several factors can impact how long your relief lasts:

Pollen severity (some years are worse than others!)
Your immune system’s reactivity
Lifestyle (e.g., exposure to high pollen areas)
Medical conditions or medications

📅 When Should You Get the Jab?

For best results, aim to get your injection:

Before the high pollen count hits (usually April–May)
Or at the first sign of symptoms returning
Same-day appointments at Ready Health mean you don’t have to wait.

🔁 Signs It’s Time for a Second Injection

Most people only need one jab per season. However, you might consider a second dose (after clinical review) if:

Your symptoms return after 6–8 weeks
You’re attending an event during high pollen exposure
Your symptoms are affecting daily life again

We’ll guide you safely — your health comes first.
