Hay Fever Injection
Fast, long-lasting relief from severe seasonal allergies
At Skinoza Clinic, we understand how debilitating hay fever can be. Constant sneezing, itchy eyes, runny nose and fatigue can make even the simplest outdoor activities exhausting.
For those who struggle to control symptoms with tablets, nasal sprays or eye drops, our Hay Fever Injection — a medically approved Kenalog® (triamcinolone) steroid injection — provides powerful, long-lasting relief throughout the allergy season.
Administered by experienced medical professionals in a safe clinical setting, this one-off treatment can dramatically reduce your symptoms for up to three months — allowing you to enjoy spring and summer again without discomfort.
What is a hay fever injection?
A hay fever injection is an intramuscular steroid injection that delivers a small dose of corticosteroid (usually Kenalog®, which contains triamcinolone acetonide) into the bloodstream.
This medication suppresses the body’s allergic and inflammatory response to pollen and other allergens, relieving common hay fever symptoms such as:
● Itchy or watery eyes
● Nasal congestion
● Sinus pressure or headaches
● Fatigue and general irritation
Unlike antihistamines or nasal sprays, which must be used daily, a single injection provides systemic, long-acting relief for the entire pollen season.
How it works
When you come into contact with pollen, your immune system releases histamine and other chemicals that cause inflammation and allergy symptoms.
Triamcinolone, the active ingredient in Kenalog, works by:
● Reducing inflammation in nasal passages and sinuses.
● Suppressing histamine release.
● Preventing the immune system from overreacting to pollen exposure.
This leads to rapid improvement in symptoms — often within 24 to 48 hours — and helps maintain relief for several weeks or even months.
Who can benefit from a hay fever injection?
This treatment is ideal for individuals who experience moderate to severe hay fever that significantly affects their quality of life. You may benefit if:
● You suffer from severe allergic rhinitis that disrupts work, study or sleep.
● You experience persistent inflammation, sinus congestion or eye symptoms despite daily treatment.
● You need reliable relief for travel or outdoor events during peak pollen months.
Our clinicians will assess your suitability based on your medical history, current health and previous treatments.
Common symptoms relieved
● Sneezing fits.
● Blocked or runny nose.
● Itchy throat, mouth or ears.
● Red, watery or swollen eyes.
● Sinus pressure or headaches.
● Fatigue, poor sleep, and difficulty concentrating.
If these symptoms are affecting your daily comfort or productivity, a hay fever injection may be the most effective seasonal solution.
Benefits of hay fever injection
● One quick treatment Lasting the entire season (6–12 weeks).
● Rapid symptom relief Within 1–2 days.
● No daily tablets or sprays required.
● Convenient for busy schedules or travel.
● Improves sleep, concentration and energy.
● Safe and clinically administered By medical professionals.
Many patients describe it as life-changing, giving them the freedom to enjoy summer again without constant medication.
What to expect during your appointment
1. Consultation and assessment
Before administering the injection, our clinician will discuss your symptoms, medical history, and any current medication. We’ll confirm that this treatment is appropriate and safe for you.
We do not recommend the injection for mild, occasional hay fever — it’s designed for patients whose symptoms are severe or unmanageable through regular medication.
2. The injection procedure
● The injection is given into a large muscle, usually the upper arm or buttock.
● It takes only a few seconds and causes minimal discomfort.
● No anaesthetic is required.
● You can leave the clinic immediately afterwards.
3. Aftercare
● Avoid strenuous exercise for the rest of the day.
● Drink plenty of water to help your body process the medication.
● Full relief is usually felt within 24–72 hours.
Duration of effect
One injection typically provides symptom relief for 8 to 10 weeks — often covering most of the pollen season.
For some patients with longer allergy periods, a second injection may be considered after clinical review, but usually no more than two injections per year are recommended.
Safety and side effects
Kenalog® injections are widely used and generally safe when administered by experienced medical professionals.
Because it’s a steroid-based medicine, it must be used responsibly and only for genuine, severe cases of hay fever.
Common mild side effects
● Slight soreness at injection site.
● Temporary facial flushing or mild headache.
● Changes in appetite or sleep for a few days.
● Occasional mood change or energy fluctuation.
Rare side effects
● Localised skin thinning at the injection site
● Temporary menstrual changes in women
● Minor immune suppression if repeated too frequently
Severe side effects are extremely rare when used occasionally and under proper medical supervision.
At Skinoza Clinic, your injection will only be given after a detailed consultation confirming that the benefits outweigh the risks.
Who should not have a hay fever injection?
You may not be suitable for this treatment if you:
● Are pregnant or breastfeeding.
● Have an active infection (viral, bacterial or fungal).
● Have poorly controlled diabetes or hypertension.
● Have a weakened immune system.
● Have a known allergy to triamcinolone or other corticosteroids.
If you are unsure, our clinician will review your medical background and help determine if an alternative allergy treatment is more appropriate.
Alternatives to the hay fever injection
For patients who prefer not to have an injection or are not suitable, we also offer guidance and alternatives including:
● Nasal steroid sprays: (e.g., fluticasone, mometasone)
● Allergen immunotherapy: (specialist referral)
● Lifestyle and environmental advice: Such as pollen-avoidance strategies.
However, for many people with persistent or severe hay fever, Kenalog® injection remains the most effective single-treatment option for lasting control.
Hay fever injection vs. tablets or sprays
| Treatment | Frequency | Onset of Relief | Duration | Suitable for |
|---|---|---|---|---|
| Antihistamine tablets | Daily | 30–60 mins | Hours | Mild to moderate symptoms |
| Nasal sprays | Daily | 1–3 days | Ongoing | Nasal congestion |
| Eye drops | 2–4× daily | 15 mins | Hours | Itchy/watery eyes |
| Hay fever injection (Kenalog®) | One injection | 24–48 hours | 6–10 weeks | Severe, persistent hay fever |
This simple comparison highlights why the injection is often chosen by patients who need long-term, convenient relief during high pollen seasons.
