Hay fever: an update on current treatments.

Most hay fever sufferers can help themselves by taking steps to avoid high levels of pollen. Where eye symptoms are severe, sodium cromoglycate eye drops are recommended. Oral antihistamines are suitable for mild to moderate symptoms. For severe nasal symptoms, corticosteroid nasal sprays are useful. As with many medicines, use by expectant and breast-feeding mothers is best avoided. If symptoms are particularly troublesome, referral to a doctor is advisable.
