Hay Fever in Ireland — Antihistamines, Steroid Sprays, and What Works
A practical hay fever guide: pollen seasons in Ireland, what to take, and when to step up.
Pollen seasons in Ireland
- Tree pollen — March to May
- Grass pollen — May to July
- Weed pollen and moulds — July to September
First-line treatment
- Non-sedating antihistamines (cetirizine, loratadine, fexofenadine) — daily through season
- Intranasal steroid sprays (mometasone, fluticasone) — most effective for nasal symptoms; needs daily use for 1–2 weeks for full effect
- Eye drops (sodium cromoglicate, olopatadine) — for itchy watery eyes
Stepping up
If single agents are not enough, combine antihistamine + nasal steroid + eye drops. For severe symptoms unresponsive to maximum OTC therapy, prescription-strength antihistamines, leukotriene antagonists, or short-course oral steroids may be considered.
Avoidance tips
- Check pollen forecasts
- Wraparound sunglasses outdoors; saline nose rinse on return
- Shower and change clothes after outdoor exposure on high-pollen days
When to consult
If OTC measures are not enough, if symptoms affect work or sleep, or if you are pregnant and need a safe option — an Online Doctor can review and prescribe.
