Frequently Asked Questions About Hay Fever

When should I take antihistamines?

Take them before allergen exposure or at the first sign of symptoms. Non-drowsy options work well during the day.

Can I use nasal spray daily?

Saline sprays are safe daily. Decongestant sprays should not exceed 3 days. Steroid sprays can be used longer under guidance.

Why are my symptoms worse at certain times?

Pollen counts peak in morning and evening. Check local pollen forecasts.

Do antihistamines make you drowsy?

Older types (e.g., promethazine) can. Newer ones (cetirizine, loratadine) are less sedating.

Can children take hay fever medicine?

Yes, but dosing varies by age and weight. Check labels or ask a pharmacist.

Good to Know

Understanding Hay Fever Triggers

Hay fever (allergic rhinitis) is essentially your immune system overreacting to particles in the air. In Australia, the most common triggers are:

Spring (Sept-Nov): Grass pollens (ryegrass is a major culprit).
Summer (Dec-Feb): Grass and weed pollens.
Autumn/Winter: Mould spores and dust mites often take over when pollen counts drop.

Pro Tip: If you know a high-pollen day is coming (check your local weather app), take your antihistamine before you leave the house. It's much easier to prevent the reaction than to stop it once the cascade of histamine has started.
