When to consult a doctor for hay fever

If symptoms persist or don’t improve

See a doctor if over-the-counter medications and home remedies are not providing relief, or if symptoms such as sneezing, itchy eyes, or nasal congestion persist for a long time or worsen.

If symptoms disrupt daily life

Medical advice is recommended if hay fever affects your sleep, breathing, work performance, or ability to concentrate, as ongoing symptoms can significantly impact quality of life.

If symptoms are frequent or unclear

Consult a doctor if you experience frequent sinus infections or ear problems linked to hay fever, or if you’re unsure whether your symptoms are due to allergies or another underlying condition.

Itchy and watery eyes

Breathing through the mouth

Snoring in sleep

Less frequent symptoms include headaches, sore throats, ear infections in children, and more.

How to prevent hay fever

Avoid exposure to allergens whenever possible
Use medications such as antihistamines and nasal sprays
Consider immunotherapy for long-term relief (Immunotherapy may provide long-term relief for some patients — speak with your GP about whether a referral to an allergist is appropriate for your situation.)
Keep windows closed to reduce pollen entry
Use air purifiers to improve indoor air quality
Make lifestyle adjustments to minimise triggers

Hola Health provides a convenient way to consult an AHPRA-registered doctor online, 24/7 across Australia.

Clinical note: A telehealth assessment can help evaluate your hay fever symptoms, recommend appropriate treatment, and issue prescriptions for antihistamines, nasal corticosteroids, or other medications if clinically indicated. Medications such as antihistamines and nasal sprays may help manage symptoms — speak with your GP or pharmacist about the most appropriate option for you. Online GPs can also provide referrals to allergists or immunologists where longer-term management such as immunotherapy is being considered. Telehealth is a complementary service — if symptoms suggest a more complex underlying condition or if allergy testing is required, your GP may recommend in-person assessment. Consultations are secure, encrypted, and Australian-stored in compliance with the Australian Privacy Principles. After-hours bulk billing is available for eligible patients during Medicare-defined periods; otherwise, private fees apply. We recommend sharing your consult summaries with your regular GP to ensure continuity of care.
