The Story
Is Pirinase Hay Fever Nasal Spray Right for You?
Hay fever affects roughly one in five people in the UK, and for many, the sneezing, congestion, and itching can make spring and summer genuinely miserable. Pirinase hay fever nasal spray is a clinically established, over-the-counter option that targets the root cause of nasal symptoms — inflammation — rather than simply masking them. Available from our allergy and hay fever range, it offers a practical, once-daily solution for adults aged 18 and over.
Each actuation delivers 50 micrograms of fluticasone propionate directly into the nasal passages. With 60 doses per bottle, you get a full month's supply at the standard adult dose, making it a cost-effective choice for managing seasonal allergic rhinitis throughout the pollen season.
How Does Pirinase Nasal Spray Work in the Body?
Fluticasone propionate belongs to a class of medicines called corticosteroids. When you spray it into your nose, it acts locally on the nasal mucosa to reduce the inflammatory response triggered by allergens like grass pollen, tree pollen, and house dust mites. It does not enter the bloodstream in significant amounts at the recommended dose, which is why it is considered well-tolerated for regular use.
- Allergen exposure triggers mast cells to release histamine and other inflammatory mediators
- Fluticasone propionate binds to glucocorticoid receptors in nasal tissue
- This suppresses the production of cytokines and other chemicals that cause swelling, mucus, and irritation
- Symptoms — including sneezing, itching, and nasal blockage — gradually reduce with consistent daily use
It is worth noting that Pirinase does not work instantly. Most people notice an improvement after three to four days of regular use, so starting treatment a few days before peak pollen season is a sensible approach.
Who Is Pirinase Hay Fever Nasal Spray Suitable For?
This product is licensed for adults aged 18 and over for the relief of seasonal and perennial allergic rhinitis. It is particularly useful if antihistamine tablets alone are not controlling your nasal symptoms, or if you prefer a targeted nasal treatment over a systemic one.
- Adults aged 18 and over with seasonal hay fever (allergic rhinitis)
- People with year-round nasal allergy symptoms triggered by dust mites or pet dander
- Those who have not found adequate relief from oral antihistamines alone
- Individuals looking for a once-daily, non-drowsy nasal treatment
It is not suitable for children under 18 without medical supervision, and you should not use it if you have an active nasal infection or have recently had nasal surgery. Always read the label before use.

Specifications of Pirinase Hay Fever Nasal Spray 60 Doses
What Is Pirinase Nasal Spray and What Is It Used For?
Pirinase Hay Fever Nasal Spray contains fluticasone propionate 50 micrograms per actuation. It is used to treat the symptoms of seasonal allergic rhinitis (hay fever) and perennial allergic rhinitis in adults aged 18 and over. Symptoms it helps relieve include a blocked or runny nose, sneezing, nasal itching, and postnasal drip. It is a Pharmacy (P) medicine available without a prescription from registered UK pharmacies.
Unlike antihistamine tablets, which work systemically throughout the body, this spray acts directly in the nasal passages. That means it targets inflammation at the source, which is why many people find it more effective for nasal congestion specifically. If you are managing multiple allergy symptoms, you may also want to explore our broader allergy and hay fever collection for complementary treatments.
What Do You Need to Know Before Using Pirinase Nasal Spray?
Before using this product, read the following carefully. There are situations where Pirinase may not be appropriate, and some medicines can interact with fluticasone propionate.
Do not use Pirinase if you:
- Are under 18 years of age (OTC use)
- Have an active nasal or sinus infection
- Have recently had nasal surgery or a nasal injury — wait until fully healed
- Are allergic to fluticasone propionate or any other ingredient in the spray
- Have tuberculosis (current or previously untreated)
Drug interactions — tell your pharmacist if you are taking:
- Ritonavir or other strong CYP3A4 inhibitors (e.g. some HIV medicines, ketoconazole) — these can significantly increase fluticasone levels in the blood
- Other corticosteroid medicines (inhaled, oral, or topical) — combined use may increase the risk of systemic corticosteroid effects
If you are pregnant or breastfeeding, speak to your GP or pharmacist before using this product. While systemic absorption is low at recommended doses, medical guidance is still advisable.
How Should You Use Pirinase Hay Fever Nasal Spray?
Using the spray correctly makes a real difference to how well it works. Follow these steps each time:
- Blow your nose gently to clear the nasal passages
- Shake the bottle gently before use
- Remove the dust cap and prime the pump if using for the first time (press down 6 times until a fine mist appears)
- Tilt your head slightly forward — do not tilt it back
- Insert the nozzle gently into one nostril, pointing it slightly away from the nasal septum
- Press the pump once while breathing in slowly through your nose
- Breathe out through your mouth
- Repeat in the other nostril
- Replace the dust cap after use and wipe the nozzle clean
| Indication | Age Group | Dose | Frequency |
|---|---|---|---|
| Seasonal allergic rhinitis | Adults 18+ | 2 sprays per nostril (200 mcg total) | Once daily |
| Perennial allergic rhinitis | Adults 18+ | 2 sprays per nostril (200 mcg total) | Once daily |
| Under 18 (OTC) | Under 18 | Not recommended without medical supervision | — |
What Are the Possible Side Effects of Pirinase Nasal Spray?
Like all medicines, Pirinase can cause side effects, although not everyone experiences them. Most side effects are mild and localised to the nose and throat.
Common side effects (may affect up to 1 in 10 people):
- Nasal irritation or dryness
- Nosebleeds (epistaxis)
- Unpleasant taste or smell
- Headache
Less common side effects (may affect up to 1 in 100 people):
- Nasal ulceration or crusting
- Perforation of the nasal septum (rare, particularly with long-term use)
- Raised intraocular pressure or glaucoma (with prolonged high-dose use)
- Hypersensitivity reactions including rash, facial swelling, or difficulty breathing — seek immediate medical attention if these occur
If you experience persistent nosebleeds, visual disturbances, or any signs of an allergic reaction, stop using the spray and contact your GP or pharmacist promptly. For those also experiencing itchy, watery eyes alongside nasal symptoms, our ear, nose and throat range includes additional options that may help.
How Should You Store Pirinase Nasal Spray?
- Store below 30°C — do not refrigerate or freeze
- Keep the bottle upright at all times
- Store away from direct sunlight and heat sources
- Keep out of the sight and reach of children

Frequently Asked Questions
Where can I buy Pirinase Hay Fever Nasal Spray online in the UK?
You can buy Pirinase Hay Fever Nasal Spray 60 Doses online from Cured Pharmacy, a GPhC-registered UK online pharmacy, for just £7.89. It is available without a prescription for adults aged 18 and over. Simply add it to your basket and it will be dispatched quickly to your door.
How does Pirinase Hay Fever Nasal Spray work in the body?
Pirinase contains fluticasone propionate, a corticosteroid that reduces inflammation in the lining of the nasal passages. When you are exposed to allergens like pollen, your immune system triggers the release of inflammatory chemicals — fluticasone suppresses this response locally. Because it acts directly in the nose rather than throughout the body, systemic side effects are minimal at the recommended dose.
How do I use Pirinase Hay Fever Nasal Spray step by step?
Blow your nose first, then shake the bottle gently. Tilt your head slightly forward, insert the nozzle into one nostril pointing slightly away from the septum, and press the pump once while breathing in slowly through your nose. Repeat in the other nostril, then breathe out through your mouth and replace the dust cap.
How long does Pirinase take to start working?
Pirinase typically takes three to four days of consistent daily use before you notice the full benefit. It is not a fast-acting rescue treatment — it works by gradually reducing nasal inflammation over time. For best results, start using it a few days before your hay fever season begins rather than waiting for symptoms to peak.
What is the correct dose of Pirinase for adults?
The standard adult dose is two sprays into each nostril once daily, giving a total daily dose of 200 micrograms of fluticasone propionate. Once your symptoms are well controlled, your pharmacist may advise reducing to one spray per nostril daily as a maintenance dose. Do not exceed two sprays per nostril per day.
What is the best time of day to use Pirinase Nasal Spray?
Most people find it easiest to use Pirinase in the morning, ideally before going outside during high pollen periods. Using it at the same time each day helps maintain consistent levels of the medicine in your nasal tissue. There is no strict requirement to use it in the morning, but a regular routine improves adherence and effectiveness.
What are the side effects of Pirinase Hay Fever Nasal Spray?
Common side effects include nasal irritation, dryness, and nosebleeds. Some people notice a mild headache or an unpleasant taste after use. Rare but more serious effects include nasal ulceration or, with prolonged high-dose use, raised eye pressure — if you notice visual changes, stop use and speak to your GP.
Is Pirinase Nasal Spray suitable for children?
Pirinase Hay Fever Nasal Spray is only licensed for over-the-counter use in adults aged 18 and over. Children under 18 should not use it without medical supervision, as a doctor may need to assess the appropriate dose and monitor for any effects on growth with long-term use. Speak to your GP if your child needs a corticosteroid nasal spray.
Can I use Pirinase if I am pregnant or breastfeeding?
If you are pregnant or breastfeeding, you should speak to your GP or pharmacist before using Pirinase. While systemic absorption is low at the recommended dose, there is limited data on its safety during pregnancy, and a healthcare professional should weigh up the benefits and risks for your individual situation.
What happens if I miss a dose of Pirinase?
If you forget to use Pirinase, simply use it as soon as you remember — unless it is nearly time for your next dose, in which case skip the missed one. Do not use a double dose to make up for a missed one. Missing the occasional dose is unlikely to cause a significant problem, but consistent daily use gives the best results.
How long can I use Pirinase Hay Fever Nasal Spray for?
Pirinase can be used throughout the hay fever season, but you should not use it continuously for more than three months without consulting a doctor or pharmacist. If your symptoms persist beyond this period or worsen, seek medical advice. Long-term unsupervised use of any corticosteroid nasal spray is not recommended.
What is the difference between Pirinase and Beconase nasal spray?
Pirinase contains fluticasone propionate, while Beconase contains beclometasone dipropionate — both are corticosteroid nasal sprays used for allergic rhinitis. Pirinase is dosed once daily (two sprays per nostril), whereas Beconase is typically used twice daily. Both are available OTC for adults aged 18 and over, and both require a few days of regular use to reach full effect.
Can I use Pirinase alongside antihistamine tablets?
Yes, Pirinase can generally be used alongside oral antihistamines for more complete hay fever symptom control. The nasal spray targets nasal inflammation directly, while antihistamines help with sneezing, itching, and eye symptoms. If you are considering combining treatments, it is worth speaking to your pharmacist — you can browse our full allergy and hay fever range for suitable options.
Does Pirinase interact with any other medicines?
The most clinically significant interaction is with strong CYP3A4 inhibitors such as ritonavir (used in HIV treatment) and ketoconazole, which can increase fluticasone levels in the blood and raise the risk of systemic corticosteroid effects. Using other corticosteroid medicines at the same time — whether inhaled, oral, or topical — may also increase this risk. Always tell your pharmacist about all medicines you are taking.
What are the latest findings on fluticasone nasal sprays for hay fever?
Intranasal corticosteroids like fluticasone propionate remain the most effective first-line treatment for moderate-to-severe allergic rhinitis according to current NHS and NICE guidance. Evidence consistently shows they outperform oral antihistamines for nasal congestion in particular. Research also supports their safety profile for seasonal use in adults when used at recommended doses.
