Are tetrahydrozoline eye drops safe for people of all ages?

Stacy Wiegman, PharmD
Pharmacy Specialist

Tetrahydrozoline is considered safe. But always check with your health-care provider. Tetrahydrozoline drops (like Murine or Optigene 3) can interact with medications, including other eye medications, high blood pressure medicines, and monoamine oxidase inhibitors (MAOIs), such as Nardil and Parnatel. When using tetrahydrozolin-containing products such as Altazine, Eye-Sine, and Geneyes make sure your hands are clean before inserting drops and do not touch the dropper directly to your eye or any other surface. To insert the drops: tilt your head back; use your index finger to pull the lower lid down and form a pocket; insert the number of drops prescribed; and keep your eyes closed without blinking.

The safety and effectiveness of tetrahydrozoline eye drops in children under the age of six is unknown; check with your health-care provider before using for children of any age.
