From the Guidelines
Olopatadine is contraindicated in patients with known hypersensitivity to olopatadine or any components of the formulation, and it should not be used in children under 3 years old for eye drops or under 6 years for the nasal spray. According to the most recent evidence from 1, olopatadine can be used in people of all ages, but with specific guidelines, such as application and common adverse effects. The study suggests that olopatadine can be used in children over 3 years old, with a recommended dosage of 2 times daily for up to 4 months, and common adverse effects include local irritation.
Key Considerations
- Olopatadine should be used with caution in patients with narrow-angle glaucoma, as it may exacerbate the condition.
- Patients with a history of hypersensitivity to olopatadine or any components of the formulation should avoid using the medication.
- The medication should not be used for contact lens-related irritation, and contact lenses should be removed before applying the eye drops and reinserted at least 10 minutes after administration.
- Caution is advised in pregnant women (Pregnancy Category C) and nursing mothers as safety has not been fully established, as noted in 1.
Important Safety Information
- If eye pain, vision changes, or worsening symptoms occur after starting olopatadine, patients should discontinue use and seek medical attention.
- Olopatadine works by blocking histamine H1 receptors, preventing mast cell degranulation, and inhibiting inflammatory mediators, making it effective for allergic conjunctivitis and rhinitis while having minimal systemic absorption and few drug interactions, as described in 1.
