Hay fever is a common allergic condition that affects millions of people in the UK every year. During the spring and summer months, pollen levels rise and many individuals begin to experience unpleasant symptoms such as sneezing, itchy eyes, and nasal congestion. While some people manage their symptoms with antihistamines or nasal sprays, others continue to struggle with severe hay fever despite using multiple treatments.
For patients with persistent seasonal allergies, a hay fever injection may offer longer-lasting relief. At Skinoza Clinic in London, we provide medical consultations and treatments for seasonal allergies, including Kenalog hay fever injections, when clinically appropriate.

What Is Hay Fever?
Hay fever, medically known as Allergic Rhinitis, is an allergic reaction to pollen from trees, grasses, or weeds. The immune system mistakenly identifies pollen as a harmful substance and releases chemicals such as histamine. This immune response causes inflammation in the nose, eyes, and airways.
Common symptoms of hay fever include:
Frequent sneezing
Runny or blocked nose
Itchy throat or ears
Red, watery, or itchy eyes
Sinus pressure
Fatigue and headaches
For some individuals, symptoms can become severe and interfere with daily activities, work performance, and sleep quality.
Why Hay Fever Symptoms Can Be Severe
The severity of hay fever varies from person to person. Some individuals only experience mild symptoms during peak pollen periods, while others develop intense reactions that last for weeks or months.
In the UK, pollen seasons typically occur during:
Tree pollen season: March to May
Grass pollen season: May to July
Weed pollen season: June to September
Grass pollen is the most common trigger of hay fever symptoms.
Environmental factors such as pollution, climate change, and prolonged pollen seasons can also worsen symptoms for many patients.
Standard Treatments for Hay Fever
Many patients manage hay fever symptoms using medications that reduce the allergic response.
Common treatments include:
Antihistamine tablets
Nasal steroid sprays
Antihistamine eye drops
Decongestant medications
Examples of commonly used antihistamines include:
Cetirizine
Loratadine
Fexofenadine
Nasal steroid sprays can also reduce inflammation inside the nasal passages. Examples include:
Fluticasone
Mometasone
While these treatments are effective for many people, some patients continue to experience severe symptoms despite using them regularly.
What Is a Hay Fever Injection?
A hay fever injection is a long-acting steroid injection used to reduce severe allergic inflammation. The medication commonly used is Triamcinolone acetonide, often known by the brand name Kenalog.
Triamcinolone belongs to a group of medications called corticosteroids. These medicines work by reducing the immune system’s inflammatory response to allergens such as pollen.
Unlike antihistamine tablets that must be taken daily, a steroid injection can provide relief for several weeks during peak pollen season.
How a Kenalog Hay Fever Injection Works
The injection is given into a muscle, usually in the upper buttock or upper arm. Once administered, the medication slowly releases into the bloodstream over several weeks.
The steroid works by:
Reducing inflammation in the nasal passages
Decreasing mucus production
Reducing eye irritation
Suppressing the allergic immune response
Many patients begin to notice improvement in symptoms within 24 to 48 hours after the injection.
The effects can last three to six weeks, although this varies between individuals.
Who May Benefit from a Hay Fever Injection?
A hay fever injection may be considered for individuals who:
Experience severe seasonal allergies
Do not respond to antihistamines or nasal sprays
Have symptoms affecting daily life or sleep
Have tried multiple treatments without improvement
Need relief during peak pollen season
However, not every patient with hay fever requires steroid injections. A consultation with a qualified clinician is necessary to determine whether the treatment is appropriate.
What Happens During the Appointment?
At Skinoza Clinic, hay fever treatment typically involves a short consultation and, if appropriate, the injection procedure.
Medical Consultation
Before treatment, the clinician will assess:
Your allergy symptoms
Medical history
Current medications
Previous allergy treatments
Any contraindications
This assessment ensures that the treatment is safe and suitable.
Injection Procedure
If appropriate, the clinician administers the injection into a muscle. The procedure is quick and usually takes only a few minutes.
Most patients can return to normal activities immediately after the appointment.
How Effective Is a Hay Fever Injection?
Many patients report significant improvement in symptoms following treatment. Benefits may include:
Reduced sneezing
Less nasal congestion
Improved breathing
Reduced itchy eyes
Better sleep
Improved comfort during pollen season
However, results vary between individuals, and some patients may still require additional medications.
Possible Side Effects
Like all medications, steroid injections can cause side effects. Most patients tolerate the treatment well, but potential side effects may include:
Facial flushing
Headache
Mood changes
Sleep disturbance
Increased appetite
Because corticosteroids affect many systems in the body, more serious side effects are possible, though less common. These may include:
Increased blood sugar levels
Elevated blood pressure
Hormonal effects
Skin thinning at the injection site
Temporary suppression of the immune system
For this reason, steroid injections should only be used after a careful clinical assessment.
Who Should Avoid Hay Fever Steroid Injections?
Some patients may not be suitable for this treatment.
The injection may not be recommended for individuals with:
Uncontrolled Diabetes mellitus
Severe Hypertension
Active infections
Glaucoma
Osteoporosis
Known allergy to corticosteroids
Pregnant or breastfeeding patients should also discuss the risks and benefits carefully with a clinician before treatment.
Alternatives to Hay Fever Injections
Before considering steroid injections, clinicians may recommend other treatments.
Antihistamines
Antihistamines block the release of histamine, reducing allergy symptoms such as sneezing and itching.
Nasal Steroid Sprays
These sprays reduce inflammation in the nasal passages and are often highly effective when used consistently.
Allergy Eye Drops
Eye drops can help relieve itchy, watery eyes.
Lifestyle Measures
Reducing pollen exposure can also help control symptoms.
Helpful measures include:
Keeping windows closed during high pollen days
Showering after outdoor activities
Wearing sunglasses outdoors
Avoiding mowing grass during pollen season
Checking pollen forecasts regularly

ConclusionBook a Consultation at Skinoza Clinic
Hay fever can significantly affect quality of life during the spring and summer months. While antihistamines and nasal sprays are effective for many people, others continue to experience persistent symptoms.
A Kenalog hay fever injection containing triamcinolone may provide longer-lasting relief for selected patients when other treatments are not effective.
However, because steroid injections affect the whole body, they should only be administered after proper medical assessment.
