Combine an oral antihistamine with a nasal corticosteroid

What to Do

Use a daily oral antihistamine (cetirizine, loratadine, or fexofenadine) plus a daily nasal corticosteroid spray (fluticasone or triamcinolone) for moderate-to-severe symptoms.

Why It Works

Antihistamines and nasal corticosteroids target different parts of the allergic response. Antihistamines block histamine receptors (reducing itch, sneeze, and runny nose), while corticosteroids reduce the underlying inflammation (reducing congestion). Together they address all major symptoms.

Tips

• This combination is recommended by allergy guidelines as step-up therapy
• Use the nasal spray consistently for 1-2 weeks to reach full effectiveness
• Adding both is more effective than doubling the dose of either alone
