Managing Hay Fever
Antihistamines
- Antihistamines offer temporary, but immediate, control of many of the most troubling symptoms of allergic rhinitis.
- Topical nasal sprays are particularly useful in patients who experience side effects of oral antihistamines, mostly xerostomia and sedation.
- Antihistamine tolerance seems to develop and alternating effective antihistamines periodically can control symptoms over the long term.
