Introduction to Methoflor
Methoflor is a brand name for an ophthalmic medication containing fluorometholone, a potent synthetic corticosteroid. Manufactured by Diamond Pharma, it is formulated as an eye drop suspension and is used to treat a variety of inflammatory conditions affecting the eye. Ocular inflammation can be caused by allergies, injury, or other non-infectious conditions, and if left untreated, can lead to discomfort and damage to the eye's delicate structures.
What is the Active Ingredient?
The active ingredient in Methoflor is fluorometholone, a type of corticosteroid. In the field of ophthalmology, corticosteroids like fluorometholone are used to reduce the symptoms of inflammation, such as swelling, redness, and itching. Unlike other corticosteroids that can significantly raise intraocular pressure, fluorometholone is generally associated with a lower risk, though long-term use still requires monitoring. Methoflor is available in two main strengths, 0.1% and 0.25%, to allow for tailored treatment based on the severity of the condition.
What is Methoflor Used For? (Indications)
Methoflor is specifically indicated for treating corticosteroid-responsive inflammation of the anterior segment of the eye. This includes inflammation affecting the following areas:
- Palpebral and bulbar conjunctiva: The membrane lining the eyelids and covering the white part of the eye.
- Cornea: The clear, dome-shaped front surface of the eye.
- Anterior segment of the globe: The front third of the eye, which includes the iris, ciliary body, and lens.
Physicians may prescribe Methoflor to manage inflammation following ocular surgery or to calm severe allergic conjunctivitis. However, it is crucial to use it only for conditions deemed appropriate by a healthcare professional, as steroid use can be dangerous in certain eye infections.
How Does Methoflor Work? (Mechanism of Action)
As a corticosteroid, fluorometholone works by inhibiting the inflammatory response. While the exact mechanism is complex and not fully understood in an ocular context, it is believed to act by suppressing the activity of phospholipase A2, an enzyme involved in the production of inflammatory mediators like prostaglandins and leukotrienes. By reducing the presence of these chemicals, fluorometholone helps to decrease swelling, redness, and discomfort in the eye. This anti-inflammatory action is localized to the eye when the drops are administered, providing targeted relief.
Important Considerations
Methoflor: Contraindications and Precautions
Despite its benefits, Methoflor is not suitable for everyone and requires careful use. It is contraindicated in patients with:
- Most viral diseases of the cornea and conjunctiva, including herpes simplex keratitis.
- Mycobacterial infections of the eye.
- Fungal diseases of ocular structures.
- Known hypersensitivity to any ingredient of the preparation.
Prolonged or inappropriate use of Methoflor can lead to serious adverse effects, including glaucoma with optic nerve damage, the formation of posterior subcapsular cataracts, and an increased risk of secondary ocular infections. Regular monitoring of intraocular pressure is essential, especially with extended use (10 days or longer).

Proper Administration and Storage
To ensure the medication is effective and safe, proper administration is critical. Adhere to these instructions:
- Wash your hands thoroughly before handling the eye drops to prevent contamination.
- Shake the bottle well before each use, as Methoflor is a suspension.
- Tilt your head back, pull down the lower eyelid to create a small pouch, and instill the prescribed number of drops.
- Avoid touching the dropper tip to your eye, fingers, or any other surface.
- Gently close your eye for a couple of minutes to allow the medication to be absorbed.
- If using other eye medications, wait at least 5-10 minutes between applications.
- Store Methoflor in an upright position and protect it from freezing.
Potential Side Effects and Adverse Reactions
While many people use Methoflor without significant issues, side effects can occur. Common, less serious side effects may include temporary blurry vision, stinging, or burning after application. More serious adverse reactions that require immediate medical attention include:
- A significant rise in intraocular pressure (glaucoma).
- The development of cataracts.
- New or worsening eye pain, redness, irritation, or discharge.
- Sudden changes in vision or seeing halos around lights.
- Perforation of the globe in conditions causing thinning of the cornea or sclera.
Since steroids can mask the signs of an eye infection, it is important to report any new or worsening symptoms to your doctor promptly.
Conclusion
Methoflor is a corticosteroid eye drop containing fluorometholone, used to treat various inflammatory conditions of the anterior segment of the eye. It works by suppressing the inflammatory response, providing relief from swelling, redness, and itching. However, due to the potential for serious side effects like glaucoma and cataracts, it should only be used under strict medical supervision and for a duration specified by a healthcare provider. Always follow the correct administration procedures and report any concerning symptoms to your doctor to ensure safe and effective treatment.
