Hay Fever in Five Minutes
Hay Fever: the whole thing in five minutes, for when you want the numbers and nothing else.
Allergic rhinitis caused by pollen, with nasal, eye and sometimes chest symptoms.
Key takeaways
- Most effective for nasal symptoms: intranasal corticosteroid spray
- Spray trial period: use consistently for about 2 weeks before judging
- Most useful single change: Start a steroid nasal spray before the season begins.
- Commonest mistake: Judging a nasal spray after two days.
- See a doctor if any of the signs under "When to speak to a doctor" below apply to you.
The numbers, in one place
| Measure | Figure |
|---|---|
| Most effective for nasal symptoms | intranasal corticosteroid spray |
| Spray trial period | use consistently for about 2 weeks before judging |
| Antihistamines | non-sedating ones for daytime use |
| Pollen seasons | tree in spring, grass in early summer, weed later |
In one paragraph
It worsens asthma control in many people, and the most effective treatment is the one people use least consistently.
Worth doing
- Start a steroid nasal spray before the season begins
- Learn correct spray technique; aim away from the septum
- Use a non-sedating antihistamine regularly through the season
- Shower and change clothes after being outdoors on high-pollen days
Worth avoiding
- Judging a nasal spray after two days
- Sedating antihistamines for daytime use
- Ignoring worsening asthma during pollen season

When to speak to a doctor
Call 999 for swelling of the lips, tongue or throat, difficulty breathing or swallowing, or collapse — that is anaphylaxis, not hay fever. Contact a GP if asthma symptoms worsen during pollen season, or if hay fever is not controlled despite regular treatment.
Where this comes from
How this page was put together
Every figure, recommendation and warning above is taken from the guidance named in Where this comes from. Nothing on this page is inferred, summarised or generalised beyond what those bodies publish: where they give a number, it is their number, and where they are silent, so are we. Pages are rebuilt whenever the underlying record changes. Sign-off by a named clinician, where it has happened, is shown at the top of the page along with the date.
