Acivir Eye Ointment (Acyclovir)

Acivir Eye Ointment:-

Acivir Eye Ointment contains Acyclovir 3% as its active ingredient. Acyclovir belongs to a class of medicines called antiviral agents specifically nucleoside analogues. It is one of the most well established, extensively studied, and widely trusted antiviral medicines available in modern medicine with several decades of safe and effective clinical use for the treatment of herpes virus infections. Acivir Eye Ointment is specifically formulated as a sterile ophthalmic ointment for direct application to the eye and surrounding structures making it suitable for treating herpes virus infections that affect the eye. It is manufactured by Cipla Ltd, one of India’s most reputable and globally recognised pharmaceutical companies. The ointment formulation provides several advantages over eye drops for antiviral treatment including longer contact time with the infected eye tissue, slower drainage, and sustained drug delivery to the corneal surface. Acivir Eye Ointment is a prescription medicine and must be used only under the strict supervision of a qualified eye doctor or ophthalmologist. It is the treatment of choice for herpes simplex virus infections of the cornea and is used in eye clinics and hospitals across India and globally for the management of this potentially serious and sight-threatening condition. It is suitable for adult patients and in some cases for children under specialist supervision.

Uses:-

Acivir Eye Ointment is prescribed for the following eye conditions:

• Herpes Simplex Keratitis: The primary and most important indication for Acivir Eye Ointment is the treatment of herpes simplex keratitis which is an infection of the cornea caused by Herpes Simplex Virus Type 1 (HSV-1). This condition causes painful corneal ulcers, reduced vision, and if untreated can lead to permanent corneal scarring and vision loss.
• Dendritic Corneal Ulcers: Treats the characteristic dendritic or branching pattern corneal ulcers caused by active HSV-1 replication on the corneal surface which are pathognomonic of herpes simplex keratitis.
• Geographic Corneal Ulcers: Used for more extensive geographic or amoeboid pattern corneal ulcers that represent a more advanced form of epithelial herpes simplex keratitis.
• Recurrent Herpes Simplex Keratitis: Used to treat recurrent episodes of herpes keratitis that can occur due to reactivation of latent herpes virus in the trigeminal ganglion.
• Herpes Simplex Blepharitis: Used to treat herpes virus infections affecting the eyelids causing vesicular blepharitis and eyelid sores in conjunction with corneal disease.
• Herpes Simplex Conjunctivitis: Used for herpes simplex virus infections affecting the conjunctiva causing viral conjunctivitis with characteristic follicular reaction.
• Prevention of Recurrent Keratitis: In some cases used prophylactically to reduce the frequency of recurrent herpes keratitis episodes under specialist guidance.

Benefits:-

• Highly effective targeted antiviral action against Herpes Simplex Virus preventing viral replication and corneal damage
• Ointment formulation provides longer contact time with the infected corneal surface compared to eye drops ensuring more sustained drug delivery
• Treatment of choice for herpes simplex keratitis endorsed by international ophthalmology guidelines
• Manufactured by Cipla Ltd, one of India’s most trusted and globally recognised pharmaceutical companies
• Well established and extensively studied medicine with decades of safe clinical use in ophthalmic herpes infections
• Reduces the risk of permanent corneal scarring and vision loss when treatment is started promptly
• Prevents progression from superficial epithelial keratitis to more serious deeper stromal involvement
• Suitable for treatment of both primary and recurrent herpes simplex keratitis episodes
• Helps shorten the duration and severity of herpes keratitis episodes when used appropriately as prescribed
• Provides targeted antiviral treatment directly at the site of infection with minimal systemic absorption

How does It Work?

Herpes Simplex Virus Type 1 (HSV-1) is a DNA virus that can infect the corneal epithelium causing herpes simplex keratitis. The virus replicates actively in the corneal epithelial cells creating characteristic dendritic ulcers and causing significant corneal damage. If left untreated or inadequately treated active viral replication can progress to deeper stromal keratitis and uveitis causing permanent scarring, reduced corneal transparency, and potentially severe and irreversible vision loss.

Acivir Eye Ointment works through the highly specific antiviral mechanism of Acyclovir targeting viral replication within infected cells.

Step 1 – Selective Activation: After entering the virus-infected corneal epithelial cells Acyclovir is first phosphorylated into Acyclovir monophosphate by a viral enzyme called thymidine kinase that is produced only by Herpes Simplex Virus infected cells. This first and crucial phosphorylation step does not occur in uninfected normal cells because normal cellular thymidine kinase phosphorylates Acyclovir very poorly. This selectivity is why Acyclovir is highly specific for virus-infected cells with minimal toxicity to normal uninfected cells.

Step 2 – Further Activation: Acyclovir monophosphate is then converted into Acyclovir diphosphate and finally into Acyclovir triphosphate by normal cellular enzymes present in both infected and uninfected cells.

Step 3 – Viral DNA Replication Inhibition: Acyclovir triphosphate is the active form of the medicine. It competitively inhibits the viral enzyme DNA polymerase which is the enzyme responsible for copying the viral DNA during replication. Acyclovir triphosphate is incorporated into the growing viral DNA chain and because it lacks the necessary chemical group to continue the chain it causes permanent and irreversible chain termination stopping all further viral DNA synthesis.

By preventing viral DNA replication Acyclovir stops new virus particles from being produced, limits the spread of infection within the corneal tissue, and allows the patient’s own immune system to clear the existing infection and begin the healing process. The ointment formulation ensures that adequate concentrations of Acyclovir are maintained on the corneal surface for the extended periods needed for effective antiviral action.

How to Use?

Follow these careful and hygienic steps every time you apply Acivir Eye Ointment:

1. Wash your hands thoroughly with soap and water before touching the tube or your eye area.
2. Check the expiry date on the tube and ensure the seal is not broken before first use.
3. Remove contact lenses before application. Do not reinsert contact lenses during the entire course of herpes keratitis treatment.
4. Tilt your head gently backwards and look upward towards the ceiling.
5. With one clean finger gently pull down your lower eyelid to create a small comfortable pocket between the eyelid and the eye surface.
6. Hold the ointment tube just above the lower eyelid pocket without allowing the tube tip to touch the eye surface, eyelid, eyelashes, or any other surface to prevent contamination.
7. Gently squeeze a small ribbon of ointment approximately 1 centimetre in length into the pocket of the lower eyelid.
8. Release the lower eyelid and close your eye gently. Gently roll the eye under the closed eyelid to help spread the ointment evenly across the eye surface.
9. Blinking a few times will help distribute the ointment across the entire corneal and conjunctival surface.
10. Expect temporary blurring of vision after application due to the ointment base. This is normal and will clear within a few minutes.
11. Wipe away any excess ointment from around the eye using a clean soft tissue.
12. If application is needed in both eyes repeat all steps for the other eye.
13. Replace the tube cap firmly and securely after every application to maintain sterility.

Dosage:-

The dosage of Acivir Eye Ointment is prescribed by the treating eye doctor based on the type and severity of the herpes eye infection.

• Standard Treatment Dose: Apply a small ribbon of ointment approximately 1 centimetre into the lower conjunctival sac of the affected eye five times daily (approximately every 4 hours during waking hours) for a minimum of 3 days after complete healing of the corneal ulcer or for a total of 7 to 10 days as directed by your doctor.
• Treatment Duration: Treatment must be continued for the full prescribed duration even if symptoms improve before the course ends. Premature discontinuation risks incomplete viral clearance and recurrence.
• For Recurrent Keratitis: The same dose and duration applies for recurrent episodes. Your doctor may also discuss the option of long-term suppressive therapy to reduce the frequency of recurrences.
• Children: Acivir Eye Ointment can be used in children under strict specialist supervision. The dose is generally the same as for adults but must be guided by a paediatric ophthalmologist.
• Missed Application: If an application is missed apply it as soon as you remember. If it is nearly time for the next application skip the missed one and continue with the regular five times daily schedule. Never apply double ointment to compensate.

Always complete the full prescribed course of antiviral treatment as directed by your eye specialist.

Side Effects:-

Acivir Eye Ointment is generally well tolerated by most patients when used as directed. Because Acyclovir is highly selective for virus-infected cells systemic side effects are extremely rare with ophthalmic use. However some patients may experience local reactions.

Common Side Effects:

• Significant temporary blurring of vision immediately after application due to the ointment base (expected and normal)
• Mild stinging or burning sensation for a short time after applying the ointment
• Mild redness or irritation of the eye after application
• Mild watering or tearing of the eye after application
• Mild sticky feeling around the eye and on eyelashes from the ointment base

Uncommon Side Effects:

• Mild superficial punctate keratopathy (small surface changes on the cornea) with prolonged use
• Mild eyelid swelling or irritation
• Mild allergic conjunctivitis in rare cases
• Feeling of something in the eye after application
• Mild sensitivity to bright light during treatment

Serious Side Effects (Rare but Seek Immediate Help):

• Severe allergic reaction including intense itching, rash, hives, or significant swelling of the face, lips, or throat
• Worsening of corneal involvement or failure of the ulcer to heal after appropriate treatment suggesting resistant virus, superimposed bacterial infection, or incorrect diagnosis
• Significant increase in eye pain, redness, or photophobia during treatment that may indicate progression to stromal keratitis requiring additional treatment
• Signs of secondary bacterial infection of the corneal ulcer including purulent discharge

If any serious or unexpected reactions occur stop using Acivir Eye Ointment and contact your eye doctor without delay.

Precautions & Safety:-

Please read the following important precautions before using Acivir Eye Ointment:

• Prescription Only: Acivir Eye Ointment is a prescription antiviral medicine. Always use under the strict supervision and guidance of a qualified ophthalmologist or eye specialist.
• Correct Diagnosis Essential: Acivir Eye Ointment works specifically against herpes simplex virus. It will not treat bacterial, fungal, or other viral eye infections. Correct diagnosis by an eye specialist before starting treatment is absolutely essential. Using antiviral ointment for other conditions will be ineffective and may delay appropriate treatment.
• Do Not Use with Steroid Eye Drops Alone: Corticosteroid eye drops alone are contraindicated in active herpes simplex epithelial keratitis as they can dramatically worsen the infection and cause serious corneal damage. If steroid treatment is needed for stromal keratitis this must be done under very close specialist supervision with adequate antiviral cover.
• Complete the Full Course: Always complete the entire prescribed course of antiviral treatment even if the eye appears completely healed before the course ends. Premature discontinuation risks viral recurrence and resistant infection development.
• Contact Lenses: Do not wear contact lenses during the entire course of herpes keratitis treatment. The infected cornea is particularly vulnerable and contact lens wear during an active herpes infection can cause serious corneal complications.
• Driving and Activities: Expect temporary but significant blurring of vision after each application. Do not drive or operate machinery immediately after applying the ointment. Apply before rest periods where possible.
• Pregnancy and Breastfeeding: Inform your doctor if you are pregnant or breastfeeding before using Acivir Eye Ointment. Although systemic absorption from ophthalmic use is minimal the safety data in pregnancy requires specific medical assessment. Use only if clearly necessary and prescribed by your doctor.
• Children: Use in children must be under strict paediatric ophthalmologist supervision with careful monitoring of both treatment response and tolerability.
• Do Not Share: Never share this ointment with another person. Herpes virus is contagious and sharing eye ointment can spread the infection.
• Tube Hygiene: Never allow the tube tip to touch any surface. Replace the cap firmly immediately after each application to maintain sterility.
• Other Eye Medicines: If using other eye drops or ointments alongside Acivir apply eye drops first, wait at least 5 minutes, and then apply Acivir Eye Ointment last as it may interfere with absorption of other drops due to its thick ointment base.
• Recurrence Prevention: Herpes keratitis is known for recurrence. Discuss with your ophthalmologist about trigger factors, long-term prevention strategies, and when to seek urgent treatment if symptoms recur.

Storage:-

• Store at room temperature between 15°C to 25°C.
• Keep the tube away from direct sunlight, heat sources, and damp or humid environments.
• Do not freeze the ointment under any circumstances.
• Always keep the cap tightly and securely closed after every application.
• Store safely and completely out of reach of children and pets at all times.
• Do not use after the expiry date clearly printed on the tube or outer carton.
• Discard the tube 28 days after first opening even if ointment still remains inside.
• Do not dispose of medicines in household waste bins or down the drain. Ask your pharmacist for guidance on safe and responsible disposal.

FAQs:-

1. How do I know if I have herpes simplex keratitis requiring Acivir Eye Ointment?

Herpes simplex keratitis typically presents with sudden onset of eye pain, significant sensitivity to light, redness, watering, and blurred vision usually affecting only one eye. The characteristic finding is a dendritic or branching pattern corneal ulcer visible under a slit lamp examination by an ophthalmologist when the cornea is stained with fluorescein dye. If you experience these symptoms it is essential to see an eye doctor urgently as herpes keratitis can progress rapidly causing serious corneal damage if diagnosis and treatment are delayed.

2. How long does it take for Acivir Eye Ointment to heal herpes keratitis?

With prompt and appropriate treatment using Acivir Eye Ointment five times daily most cases of epithelial herpes simplex keratitis show meaningful improvement within 5 to 7 days and complete healing of the corneal ulcer within 7 to 14 days in most patients. However treatment must be continued for at least 3 days after complete healing and for the full prescribed course as directed by your ophthalmologist to ensure complete viral clearance and reduce the risk of immediate recurrence.

3. Will herpes keratitis come back after treatment with Acivir?

Yes. Herpes keratitis is notorious for recurrence. The herpes simplex virus establishes lifelong latency in the trigeminal ganglion and can reactivate periodically causing recurrent episodes of keratitis triggered by factors such as sunlight exposure, fever, stress, other illness, and immunosuppression. Patients who experience frequent recurrences may benefit from long-term oral antiviral suppressive therapy to reduce recurrence frequency. Discuss your recurrence risk and prevention options with your ophthalmologist.

4. Can I use steroid eye drops at the same time as Acivir Eye Ointment?

Corticosteroid eye drops are absolutely contraindicated in active herpes simplex epithelial keratitis as they dramatically suppress the local immune response and allow unrestricted viral replication causing rapid and severe worsening of the corneal infection. Steroids may be used under very close specialist supervision for deeper stromal keratitis but only with adequate antiviral cover and never for the epithelial form. Never use steroid eye drops for a red or painful eye without first confirming with your ophthalmologist that herpes keratitis is not present.

5. Is Acivir Eye Ointment the same as Acyclovir tablets for cold sores?

Acivir Eye Ointment contains the same active ingredient Acyclovir as systemic tablets used for cold sores and genital herpes. However the ophthalmic ointment formulation is specifically designed for application to the eye and is sterile. The concentration and formulation are optimised for eye use. Oral Acyclovir tablets are absorbed systemically and work throughout the body while the eye ointment delivers high local concentrations directly to the infected cornea with minimal systemic absorption. Never apply non-ophthalmic Acyclovir skin cream or oral preparations to the eye as these are not formulated for ocular use.
