Overview of the medicine
Olopatadine nasal spray is an antihistamine used for the relief of nasal symptoms associated with seasonal allergic rhinitis in patients aged 6 years and older.
Uses & Indications
Dosage
Adults
Two sprays per nostril, twice daily. Each spray delivers 665 mcg of olopatadine.
Elderly
No specific dosage adjustment required.
Renal_impairment
No specific dosage adjustment required.
How to Take
For intranasal use only. Prime the pump (5-6 sprays) until a fine mist appears before first use or after 7 days of non-use. Blow nose gently before use. Tilt head slightly forward, insert nozzle into nostril, and spray. Repeat for other nostril.

Olopatadine is a selective H1-receptor antagonist that also inhibits the release of histamine from mast cells. It reduces allergic reactions by blocking histamine's effects.
