Hayfever commonly causes itchy, watery eyes and nasal congestion. Eye drops formulated for allergies can reduce itching and redness, while steroid or antihistamine nasal sprays decrease inflammation and congestion. Proper technique matters: aim sprays away from the nasal septum and inhale gently. For persistent symptoms, a combination of oral antihistamines for immediate relief and nasal steroids for long-term control is often effective. Always check interactions with other medications and consult a pharmacist if you are pregnant, breastfeeding or managing other health conditions.
