Conceptual AI-generated illustration accompanying information about allergic rhinitis and hay fever; not a clinical photograph.
Hay fever treatment works best when it matches the problem: occasional itching and sneezing, persistent nasal blockage, troublesome eyes, or symptoms that disrupt sleep. Medicines can control allergic rhinitis, but they do not usually remove the underlying allergy. Specialist allergen immunotherapy can offer longer-lasting benefit for selected people.

This adult guide helps you prepare a practical discussion with a pharmacist or clinician. It is not a diagnosis, a dosing schedule or advice to change a prescription.
Check the pattern before treating every runny nose as an allergy
Allergic rhinitis often causes repeated sneezing, an itchy nose and watery, itchy eyes soon after exposure to a trigger. Pollen causes seasonal hay fever; dust mites, animal dander and mould can produce symptoms at other times. A runny nose can also come from infections or non-allergic irritation. If the cause is uncertain, treatment failure is a reason to review the diagnosis. NHS allergic rhinitis
For your appointment, note where symptoms occur, whether they follow outdoor exposure or contact with an animal, and how they affect sleep or work. Take photographs of medicine labels and record how consistently you use them. This gives the clinician more useful information than simply saying that an allergy tablet stopped working.
Choose a treatment category with a pharmacist
Antihistamines block histamine’s effects and can help itching, sneezing and a runny nose. Less-sedating versions are generally preferable for daytime use, although even these can make some people sleepy. A nasal antihistamine is another option; availability and age limits vary between countries and products. NHS antihistamines
A corticosteroid nasal spray reduces inflammation and is an important option when nasal symptoms are persistent. The 2020 US practice parameter favours it as a single treatment for persistent allergic rhinitis. The newer ARIA–EAACI 2024–2025 guidance also supports nasal corticosteroids and suggests a combined nasal antihistamine–corticosteroid product for some patients, particularly when symptoms are more severe. The choice depends on benefit, tolerability, cost and your priorities. US rhinitis practice parameter, ARIA–EAACI guidance
Do not judge a steroid spray by the first few minutes. Fluticasone, for example, can take several days to reach full effectiveness. Follow its leaflet and agreed treatment plan rather than repeatedly switching or adding products. Official fluticasone patient labelling
Check spray technique before assuming it has failed
Ask a pharmacist to watch your technique. Typically, you gently clear the nose, keep your head slightly forward and point the nozzle towards the outer side of the nostril, away from the central dividing wall. A gentle breath helps; a hard sniff can send medicine down your throat. Prime and clean the device as its instructions require. NHS nasal-spray technique
Steroid sprays can cause local irritation or nosebleeds. Persistent bleeding, pain or troublesome side effects should be reviewed rather than answered by increasing the amount. NHS fluticasone side effects
Tell the pharmacist about other steroid medicines and all prescriptions: fluticasone can interact with medicines including ritonavir, cobicistat and some antifungals. NHS fluticasone interactions
Reduce exposure and consider saline
Aim exposure changes at the trigger you actually have. During high-pollen periods, wraparound sunglasses and drying laundry indoors may help reduce exposure. For indoor triggers, damp dusting, addressing mould or damp, and keeping pets out of bedrooms are practical starting points. They cannot guarantee complete avoidance or replace effective treatment when symptoms remain troublesome. NHS prevention advice
Saline rinsing may ease symptoms. A 2018 Cochrane review, based on searches through November 2017, found low- or very-low-certainty evidence. It could not establish whether saline was as effective as steroid sprays or how much extra benefit it added to medicines. Treat it as an optional comfort measure, not a proven substitute. Cochrane saline review
Use distilled, sterile, or previously boiled and cooled water in a rinsing device, and clean the device as directed. Plain tap water is unsuitable for nasal rinsing. CDC rinse safety
Avoid common medicine and supplement traps
Decongestant sprays are different from steroid sprays. Prolonged use can worsen congestion; follow the specific label rather than making them a daily allergy routine. Pregnancy, high blood pressure, heart disease and interacting medicines warrant professional advice. NHS decongestants
Alcohol can increase antihistamine-related drowsiness, and cough-and-cold products may already contain an antihistamine. Do not drive if affected. Children, older adults, people who are pregnant or breastfeeding, and those with other illnesses need product-specific advice. NHS antihistamine safety
Local honey has no convincing evidence as a hay fever treatment. Butterbur has safety concerns, and variable probiotic preparations make firm recommendations difficult. “Natural” does not establish safety or an allergy cure. NCCIH seasonal-allergy evidence
When specialist treatment or urgent help matters
If symptoms still disturb sleep or daily life despite correctly used treatment, ask about assessment and, where appropriate, allergy testing. Immunotherapy targets a confirmed trigger over a prolonged course. It can give lasting relief, but some people relapse, and injections can rarely cause anaphylaxis. Treatment requires specialist selection and supervision. AAAAI immunotherapy guidance
Long-term benefit is supported by primary research, including a 1999 trial in selected adults with grass-pollen allergy after several years of treatment. This is evidence for a specific treatment approach, not a guarantee that every allergy will be permanently cured. Original immunotherapy trial
Worsening asthma needs prompt clinical advice. Sudden throat or tongue swelling, breathing difficulty or fainting requires emergency help rather than another allergy tablet. NHS allergic rhinitis review advice, NHS anaphylaxis guidance
