What is Hay Fever?
Hay fever, also known as allergic rhinitis, is a common allergic condition caused by the immune system reacting to pollen. While pollen is harmless to most people, those with hay fever experience an exaggerated immune response, leading to inflammation of the nose, eyes, and airways.
Hay fever symptoms in Glasgow typically occur between April and September, although this can vary depending on weather patterns, local plant species, and individual sensitivity to different pollens. Tree pollen is more common in early spring, grass pollen peaks in late spring and summer, and weed pollen tends to appear later in the season.
As pollen levels rise, symptoms often become more persistent and disruptive. For many people, hay fever can affect sleep, concentration, and overall quality of life. With normal symptoms being, runny or blocked nose, itchy or sore eyes, frequent sneezing and tiredness.
Advanced Hay Fever Treatments including injections
For some people, hay fever symptoms remain severe despite using tablets, nasal sprays, and eye drops. In these cases, a clinician-led consultation may be appropriate to discuss additional prescription-only treatment options.
If suitable, our clinician will explain the potential benefits, risks, and alternatives during your consultation.
A corticosteroid injection may be considered following medical assessment.
This treatment is sometimes referred to as a “hay fever injection” and uses a long-acting corticosteroid to help reduce inflammation associated with allergic rhinitis.

Frequently Asked Questions
Information about the hay fever injection is provided for educational purposes and is discussed in detail only following a medical consultation. Not all treatments are suitable for everyone, and treatment may be declined if it is not clinically appropriate.
What is a hay fever injection?
A hay fever injection is a medical treatment used for people with severe allergic rhinitis whose symptoms are not controlled with standard treatments such as antihistamine tablets, nasal sprays, or eye drops. It involves the administration of a long-acting corticosteroid, which works by reducing the immune system’s inflammatory response to pollen.
This treatment is sometimes referred to as a “hay fever jab” and is considered only after other options have been tried.
How does the hay fever injection work?
The injection delivers a corticosteroid into the body, where it gradually reduces inflammation associated with pollen allergies. By calming the immune response, it can significantly reduce symptoms such as sneezing, nasal congestion, itchy eyes, and sinus pressure.
Symptom improvement typically begins within 24–48 hours and may last for several weeks or, in some cases, most of the pollen season.
Who is suitable for a hay fever injection?
A hay fever injection may be suitable for adults who:
– Experience moderate to severe hay fever symptoms
– Have tried over-the-counter treatments without sufficient relief
– Have also used prescribed antihistamines or nasal sprays
– Find that hay fever significantly affects sleep, work, or daily life
Suitability is determined following a medical consultation, where previous treatments, medical history, and overall health are reviewed.
Who is not suitable for a hay fever injection?
This treatment is not suitable for everyone. A hay fever injection may not be offered in the following situations:
Mild or well-controlled symptoms
If hay fever symptoms are manageable with antihistamines, nasal sprays, or eye drops, an injection is usually not appropriate.
Standard treatments not yet tried
The injection is generally considered only after first-line treatments (such as antihistamines and steroid nasal sprays) have been tried and found ineffective or unsuitable.
Certain medical conditions
People with a history of conditions that may be worsened by corticosteroids may not be suitable, including:
Poorly controlled diabetes
High blood pressure that is not well controlled
Osteoporosis
Glaucoma
Active or recurrent peptic ulcer disease
Significant heart disease
A history of serious mental health conditions that may be affected by steroids
Active or recurrent infections
Corticosteroids can suppress the immune system, so the injection may not be appropriate if there is an ongoing infection.
Pregnancy or breastfeeding
Hay fever injections are generally avoided during pregnancy and breastfeeding unless there is a clear clinical indication and specialist advice.
Previous adverse reaction to steroid injections
Anyone who has experienced significant side effects or allergic reactions to corticosteroids may not be suitable.
Concerns about risk versus benefit
If, following assessment, the potential risks or side effects are felt to outweigh the expected benefits, the injection may be declined.
The hay fever injection is considered a last-resort treatment and will only be offered if it is clinically appropriate following a full medical assessment.
Are there side effects from a hay fever injection?
As with all corticosteroid treatments, there is a risk of side effects. These vary depending on individual health factors and medical history. Potential risks and side effects will be explained in full during your consultation, and you will be provided with patient information before making a decision. You can read more about it by clicking here.
How long does a hay fever injection last?
For many people, a single injection can provide symptom relief for several weeks or months. However, the duration of benefit varies between individuals and cannot be guaranteed.
Is the hay fever injection available on the NHS?
Hay fever injections are not routinely available on the NHS. They are typically offered through private clinics following a medical assessment.
The hay fever injection is prescribed off-licence. This means that while the medication is licensed in the UK for certain medical conditions, its use for hay fever is not specifically included in the manufacturer’s licence. Prescribing a medicine off-licence is a recognised and common medical practice, where a clinician uses their professional judgement to prescribe a medication when they believe it is appropriate and in the patient’s best interests, based on available evidence and clinical experience.
Before treatment, a full assessment is carried out to ensure the injection is suitable, and the potential benefits and risks are discussed in detail.
What side effects are associated with the hay fever injection?
As with any medication, the hay fever injection (a corticosteroid) can cause side effects. Most people do not experience significant problems, but side effects can occur, particularly because this is a long-acting steroid.
Common or mild side effects
These are usually temporary and may include:
Pain, redness, or bruising at the injection site
Headache
Facial flushing or warmth
Difficulty sleeping for a short period
Increased appetite or mild mood changes
Less common side effects
These occur less frequently but may include:
Temporary changes in mood or anxiety
Raised blood sugar levels (particularly in people with diabetes)
Fluid retention or mild swelling
Changes in blood pressure
Rare but more serious side effects
Serious side effects are uncommon, but can include:
Suppression of the body’s natural steroid production
Increased risk of infection
Thinning of the skin or delayed wound healing
Effects on bone strength (osteoporosis) with repeated use
Changes in vision, such as raised eye pressure or cataracts
Altered menstrual cycle
Long-term or repeated use
Repeated steroid injections can increase the risk of systemic side effects. For this reason, hay fever injections are:
Not given routinely
Limited in frequency
Considered only when symptoms are severe and other treatments have been ineffective
