Understanding the Use of Ketofall
Ketofall is a brand of eye drops containing the active substance ketotifen. It is specifically used for the symptomatic treatment of seasonal allergic conjunctivitis, commonly known as hay fever. Allergic conjunctivitis is an inflammation of the conjunctiva (the membrane that lines the inside of your eyelids and the whites of your eyes) caused by an allergic reaction. Symptoms include itchy, red, and watery eyes, which can be triggered by allergens like pollen, dust mites, or animal dander.
The Dual Mechanism of Action
Ketotifen, the active ingredient in Ketofall, employs a dual mechanism of action to provide relief from allergic eye symptoms. This two-pronged approach makes it more comprehensive than some other allergy eye drops.
Antihistamine Action
- Blocks Histamine: When the body encounters an allergen, it releases histamine, a natural substance that triggers allergic symptoms. As an antihistamine, ketotifen blocks the effect of histamine, quickly relieving itching and redness.
Mast Cell Stabilizer Action
- Prevents Histamine Release: The medication also works as a mast cell stabilizer. Mast cells are immune cells that store histamine. Ketotifen prevents these cells from releasing histamine in the first place, stopping the allergic reaction before it fully begins.
This combination of both immediate relief and preventative action makes Ketofall a powerful tool in managing seasonal eye allergies.
Administration
To ensure maximum effectiveness and safety, Ketofall eye drops must be administered correctly. The medication is for topical ocular use only.
Instructions for use:
- Wash your hands thoroughly with soap and water before handling the eye drops.
- Open one single-dose container by twisting off the top.
- Tilt your head back and gently pull down your lower eyelid to form a small pocket.
- Squeeze the single-dose container to place a drop into the pocket.
- Avoid touching the tip of the container to your eye or any other surface to prevent contamination.
- Release the lower eyelid and gently close your eye for a few minutes to allow the drop to be absorbed.
- If you need to use a second drop in the same eye, follow the instructions provided by a healthcare professional.
- Discard the single-dose container and any remaining solution after use, as it contains no preservatives.
The appropriate frequency of administration should be determined by a healthcare professional.
Potential Side Effects
While Ketofall is generally well-tolerated, some individuals may experience side effects. It is important to be aware of these and know when to seek medical advice.
Common side effects include:
- Temporary burning or stinging after application
- Blurred vision
- Dry eyes
- Eye irritation or pain
- Headache or drowsiness
Serious side effects are rare but require immediate attention. These include:
- Eye pain or changes in vision
- Signs of an allergic reaction, such as swelling of the face, lips, or tongue
- Eye itching that worsens or persists for more than 72 hours

Important Considerations
- For External Use Only: This medication is strictly for use in the eyes and should never be taken orally.
- Interactions: While no significant interactions with Ketofall eye drops have been identified, if you are using other eye medications, you should follow the guidance of a healthcare professional regarding the timing of applications. Oral forms of ketotifen may interact with other medications, but this is not typically a concern with topical eye drops.
- Pregnancy and Breastfeeding: Ketofall can be used during breastfeeding, as systemic absorption from eye drops is minimal. During pregnancy, it is recommended to exercise caution and consult a doctor.
- Storage: Store Ketofall below 25°C and do not freeze. After opening the foil pouch, the single-dose containers should be used within four weeks.
Conclusion
In conclusion, the use of Ketofall is centered on providing relief for seasonal allergic conjunctivitis. The prescription-only eye drops contain ketotifen, a powerful dual-action antihistamine and mast cell stabilizer that addresses both the immediate symptoms of eye itching and the underlying allergic reaction. Its preservative-free formula in single-dose vials makes it a safe option for many patients, including contact lens wearers, when used correctly. However, as with any medication, it is important to follow the instructions provided by a healthcare professional and consult them, particularly if symptoms worsen or if you experience any concerning side effects.
