WARNING

Idoxuridine ophthalmic solution is a medication primarily used to treat certain viral eye infections. Like all medications, it can cause side effects in some individuals. Common side effects of idoxuridine ophthalmic may include:

• Eye irritation: Some people may experience temporary burning, stinging, or irritation in the eyes after using idoxuridine drops.
• Blurred vision: Occasionally, idoxuridine ophthalmic may cause temporary blurred vision immediately after administration. This usually resolves quickly.
• Redness and itching: Some individuals may experience redness or itching in the eyes after using idoxuridine drops. This may be a sign of irritation or allergic reaction.
• Sensitivity to light: Idoxuridine ophthalmic can sometimes increase sensitivity to light, causing discomfort when exposed to bright light.
• Conjunctivitis: In some cases, idoxuridine drops may cause inflammation of the conjunctiva, the thin membrane that covers the white part of the eye and lines the inside of the eyelids.
• Allergic reactions: Although rare, some people may be allergic to idoxuridine or other ingredients in the eye drops, leading to symptoms such as swelling, itching, or rash around the eyes.
• Corneal toxicity: Prolonged use of idoxuridine ophthalmic can potentially lead to damage to the cornea, the clear outer layer of the eye, especially if used in high doses or for an extended period.

It’s important to note that not everyone will experience these side effects, and some individuals may not experience any side effects at all. If you experience any persistent or severe side effects while using idoxuridine ophthalmic, it’s essential to consult your healthcare provider for guidance. They can help determine whether the medication is appropriate for you and recommend alternative treatments if needed.

Why is this medication prescribed?

Idoxuridine ophthalmic is prescribed primarily for the treatment of certain viral eye infections, particularly those caused by the herpes simplex virus (HSV) and the vaccinia virus. These infections can include herpes keratitis, a viral infection of the cornea, and herpetic dendritic ulcers, which are branching ulcers on the cornea caused by the herpes simplex virus.

Idoxuridine works by interfering with the replication of the virus, thus helping to control the infection and alleviate symptoms such as pain, redness, and inflammation in the eye.

How should this medicine be used?

When using idoxuridine ophthalmic, it’s essential to follow your healthcare provider’s instructions carefully. Typically, the recommended dosage is to apply one or two drops into the affected eye(s) every two hours during waking hours for the first two days of treatment. After that initial period, the frequency of dosing may be reduced to every four hours during waking hours for up to seven more days, or as directed by your doctor.

Here are some general guidelines for using idoxuridine ophthalmic:

• Wash your hands thoroughly before using the eye drops.
• Tilt your head back slightly and pull down your lower eyelid to create a small pocket.
• Hold the dropper directly over your eye and instill the prescribed number of drops into the pocket formed by the lower eyelid. Be careful not to touch the dropper tip to your eye or any surface to avoid contamination.
• Close your eye gently for a few moments to allow the medication to spread evenly over the surface of the eye.
• If you are using idoxuridine drops in both eyes, repeat the process for the other eye if directed to do so.
• Replace the cap on the dropper bottle tightly after each use to prevent contamination and keep the medication sterile.
• If you are also using other eye medications, wait at least 5 minutes between applying different eye drops to allow each medication to be absorbed properly.

It’s essential to use idoxuridine ophthalmic for the full course of treatment prescribed by your doctor, even if your symptoms improve before the medication is finished. Stopping treatment too early can allow the infection to return or worsen. If you have any questions or concerns about how to use idoxuridine ophthalmic or about your treatment plan, be sure to consult your healthcare provider for guidance.

Other uses for this medicine

• Treatment of other viral eye infections: While idoxuridine is primarily indicated for herpes simplex virus infections, it may also be used off-label for other viral eye infections, such as those caused by varicella-zoster virus (the virus that causes chickenpox and shingles) or adenovirus.
• Prophylaxis: In some cases, idoxuridine ophthalmic may be used prophylactically to prevent the recurrence of viral eye infections in individuals who are prone to frequent outbreaks, such as those with a history of recurrent herpes simplex keratitis.

What special precautions should I follow?

Regarding special precautions for using idoxuridine ophthalmic, here are some important considerations:

• Allergy: Before using idoxuridine drops, inform your healthcare provider if you have any allergies, especially to idoxuridine or other medications.
• Contact lenses: Remove contact lenses before applying idoxuridine ophthalmic, as the medication may contain preservatives that can be absorbed by contact lenses. Wait at least 15 minutes after using the drops before reinserting contact lenses.
• Pregnancy and breastfeeding: If you are pregnant, planning to become pregnant, or breastfeeding, discuss the risks and benefits of using idoxuridine ophthalmic with your healthcare provider before starting treatment.
• Children: The safety and efficacy of idoxuridine ophthalmic in children have not been established. Use in pediatric patients should be done under the guidance of a healthcare professional.
• Avoiding contamination: To prevent contamination and maintain sterility, do not touch the dropper tip of the idoxuridine bottle to any surface, including the surface of the eye or fingers. Keep the bottle tightly closed when not in use.
• Follow-up appointments: Regular follow-up appointments with your healthcare provider may be necessary to monitor your response to treatment and assess for any potential side effects or complications.

As always, it’s essential to follow your healthcare provider’s instructions and advice when using idoxuridine ophthalmic or any other medication. If you have any questions or concerns about using this medication, don’t hesitate to discuss them with your doctor or pharmacist.

However, if it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not double the dose to catch up.
