Optivar (azelastine)

Indications

• Optivar eye drops are indicated for the treatment of itchy eyes associated with allergic conjunctivitis.
• Used to relieve symptoms such as eye itching, redness, and swelling caused by allergens like pollen, dust, and pet dander.

Dosage and Administration

• Use Optivar eye drops exactly as prescribed by your doctor, typically one drop in each affected eye twice daily.
• Wash your hands thoroughly before applying the eye drops.
• Tilt your head back, pull down the lower eyelid to create a small pocket, and instill one drop into the pocket.
• Close your eyes gently for a minute or two and avoid blinking or rubbing your eyes.
• If you wear contact lenses, remove them before using Optivar eye drops and wait at least 10 minutes before reinserting them.
• Follow the dosing schedule consistently to achieve the best results.
• Do not touch the dropper tip on any surface, including your eye, to avoid contamination.

• Do not use other eye medications unless prescribed by your doctor and spaced at least 10 minutes apart from Optivar.
• Do not skip doses or stop using the eye drops without consulting your doctor, even if your symptoms improve.

Mechanism of Action

Optivar contains azelastine, an antihistamine that works by blocking histamine receptors in the eyes. Histamine is a substance produced by the body during an allergic reaction that causes itching, redness, and swelling. By blocking these receptors, Optivar reduces these symptoms and provides relief from allergic conjunctivitis.
