Ridinox 0.1% Eye Drop

Introduction

Ridinox is a prescription medication containing the active ingredient Idoxuridine. It is available under the brand name Ridinox. This medication is primarily used to treat viral eye infections, including herpes simplex keratitis.

Uses

Ridinox is prescribed for the treatment of viral eye infections caused by the herpes simplex virus. It is specifically indicated for herpes simplex keratitis, which is an infection that affects the cornea of the eye.

Dosage and Administration

The dosage and administration of Ridinox should be determined by your healthcare provider. It is typically recommended to instill one to two drops into the affected eye(s) every four hours while awake, for a period of five to seven days. Follow the instructions provided by your healthcare provider and not exceed the recommended dosage.

To administer the eye drops, wash your hands thoroughly and tilt your head back. Gently pull down the lower eyelid to create a small pocket. Squeeze the prescribed number of drops into the pocket, being careful not to touch the dropper tip to your eye or any other surface. Close your eyes gently for a few moments to allow the medication to spread evenly over the surface of the eye. If you are using other eye medications, wait at least five minutes before applying them.

Mechanism of Action

Idoxuridine, the active ingredient in Ridinox, belongs to a class of medications called antivirals. It works by inhibiting the replication of the herpes simplex virus in the infected eye. By interfering with the virus’s ability to replicate, Idoxuridine helps reduce the severity and duration of the viral eye infection.

Side Effects

Common side effects may include burning or stinging sensation in the eye(s), temporary blurred vision, and increased sensitivity to light. These side effects are usually mild and transient.

Serious side effects are rare but may include severe eye irritation, eye pain, swelling, redness, or discharge. If you experience any of these serious side effects or any other unexpected symptoms, contact your healthcare provider immediately.
