Geneye Extra is for ophthalmic (eye) use only. It should not be taken by mouth. Always follow the directions on the product label precisely.
- Preparation: Wash your hands thoroughly before handling the eye drops.
- Application:
- Tilt your head back slightly.
- Gently pull down your lower eyelid to create a small pocket.
- Hold the dropper above the eye with the tip pointing downwards.
- Look up and away from the dropper, and gently squeeze out the prescribed number of drops into the pocket.
- Avoid touching the tip of the dropper to your eye, eyelids, or any other surface to prevent contamination.
- Close your eye gently (do not blink excessively) and, if possible, press your finger lightly to the inside corner of your eye (near the nose) for about 1 minute. This helps to prevent the liquid from draining into your tear duct and being absorbed systemically.
- Wipe away any excess liquid around the eye with a clean tissue.
- Dosage: Typically, 1 to 2 drops in the affected eye(s) up to 4 times a day. Do not use more than recommended.
- Duration: Geneye Extra is for temporary relief. Do not use for more than 72 hours (3 days). If redness or discomfort persists, worsens, or if eye pain or changes in vision occur, discontinue use and consult a healthcare professional immediately.
- Contact Lenses: Remove contact lenses before applying Geneye Extra. Wait at least 15 minutes before reinserting soft contact lenses, as the preservative in the drops can be absorbed by the lenses and cause discoloration or irritation.
The primary active ingredient in Geneye Extra, tetrahydrozoline, belongs to a class of drugs known as ophthalmic decongestants. It works directly on the blood vessels in the conjunctiva (the clear membrane covering the white part of the eye and the inside of the eyelids).
When eyes are irritated, these blood vessels become dilated, leading to visible redness. Tetrahydrozoline acts as an alpha-adrenergic agonist, causing these blood vessels to constrict or narrow. This reduction in blood vessel size decreases the blood flow to the surface of the eye, thereby reducing redness and minor swelling, and alleviating associated discomfort.
While generally well-tolerated when used as directed, Geneye Extra can cause side effects.
- Common Side Effects:
- Mild burning or stinging upon instillation.
- Blurred vision (temporary, immediately after application).
- Dilated pupils (temporary).
- Watery eyes.
- Paradoxical increase in redness (“rebound redness”) if used excessively or for too long.
- Serious (but less common) Side Effects (Seek immediate medical attention if any of these occur):
- Ongoing or worsening eye redness (beyond 72 hours of use).
- Eye pain.
- Changes in vision.
- Allergic reaction (hives, difficulty breathing, swelling of face/lips/tongue/throat).
- Systemic effects due to absorption, especially with overuse: chest pain, fast or uneven heart rate, severe headache, buzzing in the ears, anxiety, confusion, or feeling short of breath. These are more likely in sensitive individuals or those with underlying conditions.
- Do Not Use If: You have narrow-angle glaucoma or are allergic to any ingredient in the drops.
- Consult a Healthcare Professional Before Use If You Have:
- Glaucoma.
- Heart disease, high blood pressure.
- Diabetes.
- A thyroid disorder.
- An eye injury or infection.
- Severe eye pain, headache, rapid vision changes, or sudden appearance of floating spots (these may indicate a serious condition requiring immediate medical attention).
- Rebound Redness: Prolonged or excessive use can lead to a phenomenon known as “rebound redness,” where the eyes become more red and irritated once the effects of the drops wear off, creating a cycle of dependence.
- Contamination: Do not touch the dropper tip to any surface. Discard the bottle after the expiration date or within the recommended period after opening (usually 28 days to a month) to prevent contamination and infection.
- Pregnancy and Breastfeeding: Consult a healthcare professional before use if pregnant or breastfeeding.
Children: Keep out of reach of children. Accidental ingestion, particularly by young children, can lead to serious adverse events and requires immediate medical attention.
While Geneye Extra is applied topically to the eye, systemic absorption (absorption into the bloodstream) can occur, especially with prolonged or excessive use. Therefore, it can potentially interact with other medications. It is important to inform a healthcare professional about all other medications, including oral drugs, other eye drops, and supplements.
- Monoamine Oxidase Inhibitors (MAOIs): Concurrent use with or within 14 days of discontinuing MAOIs (certain antidepressants or Parkinson’s medications) can lead to a dangerous increase in blood pressure due to potential systemic absorption of tetrahydrozoline.
- Tricyclic Antidepressants (TCAs): The effects of ophthalmic vasoconstrictors like tetrahydrozoline may be potentiated by TCAs, potentially leading to increased systemic side effects.
- Blood Pressure Medications: If enough tetrahydrozoline is absorbed systemically, it could potentially interfere with the action of blood pressure-lowering medications, or contribute to increased blood pressure, especially in individuals prone to hypertension.
- Other Ophthalmic Preparations: If you are using other eye drops, wait at least 5 to 10 minutes between applications to ensure each medication has time to be absorbed and to prevent dilution.
The standard dosage for Geneye Extra is:
- Adults and Children 6 years and older: Instill 1 to 2 drops in the affected eye(s) up to 4 times a day.
- Children under 6 years: Consult a healthcare professional before use.
- Important: Do not exceed the recommended dose or duration of use (maximum 72 hours). If symptoms persist or worsen, discontinue use and consult an eye care specialist.
“Geneye Extra” (tetrahydrozoline ophthalmic) is typically an Over-The-Counter (OTC) medication. This means it can be purchased without a doctor’s prescription from pharmacies and other retail locations that sell health products.
