Eye Mo Regular Eyedrop

Eye Mo Regular Eyedrop is an ophthalmic (eye) solution formulated with two active ingredients, tetrahydrozoline hydrochloride and zinc sulfate, combining a vasoconstrictor-type redness reliever with a mild astringent. It is sold in Malaysia and Singapore as an OTC (Over-the-Counter) eye care product, available from pharmacies and licensed online pharmacies without needing a doctor’s prescription for routine, short-term use.

Tetrahydrozoline hydrochloride is an alpha-adrenergic agonist commonly formulated at low concentration in over-the-counter eye drops, while zinc sulfate is included as a mild astringent that has traditionally been paired with vasoconstrictors in multi-action eye drop formulations. The exact concentration of each active ingredient is stated on the product’s carton and bottle label — customers should check this printed information rather than assuming it matches other tetrahydrozoline-containing eye drops they may have used.

Eye Mo Regular Eyedrop is typically supplied in a small dropper bottle (commonly around 7.5ml) designed for controlled, drop-by-drop application, and is intended for occasional, short-term use rather than continuous daily application. As with all eye drop products, sterile technique when applying the drops is important to avoid contaminating the dropper tip or the remaining solution in the bottle.

• Wash your hands thoroughly before handling the bottle.
• Tilt your head back slightly and gently pull down the lower eyelid to form a small pocket.
• Instil 1 to 2 drops into the affected eye(s), without letting the dropper tip touch the eye, eyelid, or any other surface.
• Close your eyes gently for 1-2 minutes and apply light pressure at the inner corner of the eye to reduce drainage into the tear duct.
• Repeat up to 4 times daily, or as directed on the pack, leaving at least a few hours between doses.
• If you wear contact lenses, remove them before applying the drops and wait at least 15 minutes before reinserting them.

The typical adult dose is 1 to 2 drops in the affected eye(s), up to 4 times a day, and this product is generally not recommended for children under 6 years unless a doctor has specifically advised it. Do not use more often or for longer than directed on the pack — using a redness-relieving eye drop for more than about 3 consecutive days can cause a rebound worsening of eye redness once the drops are stopped. If eye redness, irritation, or discomfort persists for more than 72 hours, or worsens at any point, stop use and see a doctor or pharmacist rather than continuing to self-treat with eye drops.

Use before the expiry date printed on the carton and bottle. Once opened, most multi-dose eye drop bottles should be discarded within 4 weeks (or the timeframe stated on the pack), even if solution remains, because the sterility of the remaining drops cannot be guaranteed after that point — check your specific pack for an exact in-use period.

Store below 25°C (or as stated on the pack), away from direct sunlight and heat, and keep the cap tightly closed between uses to protect the remaining solution from contamination. Keep out of reach and sight of children. Do not use the drops if the solution has changed colour or become cloudy, or if the dropper tip has been damaged or contaminated.

• Common: Mild, temporary stinging or burning sensation immediately after application.
• Common: Temporary blurred vision lasting a few seconds to minutes after instilling the drops.
• Uncommon: Increased eye dryness or a foreign-body sensation.
• Uncommon: Rebound redness or irritation if the drops are used more frequently or for longer than directed.
• Serious (seek urgent care): Severe eye pain, marked vision changes, significant swelling of the eye or eyelid, or signs of an allergic reaction (facial swelling, difficulty breathing) require prompt medical attention.

• Known hypersensitivity or allergy to tetrahydrozoline, zinc sulfate, or any other listed ingredient.
• Narrow-angle glaucoma or other diagnosed eye conditions, unless a doctor has specifically approved use.
• Children under 6 years of age, unless directed by a doctor.
• Use with soft contact lenses in place, or on eyes with an injury or infection showing visible discharge — remove lenses first and seek medical advice for infected or injured eyes rather than self-treating.

• Avoid using together with other vasoconstrictor-type eye or nasal decongestant drops, as combining products with a similar mechanism may increase the risk of rebound irritation.
• Tell your doctor or pharmacist if you are taking a monoamine oxidase inhibitor (MAOI) or certain other blood-pressure medicines, as systemic absorption of tetrahydrozoline (though minimal with normal eye-drop use) could theoretically interact with these; check first if you use this class of medicine.
• No specific food interactions are known for this product.

• Always wash your hands before applying eye drops.
• Avoid letting the dropper tip touch your eye, eyelashes, or fingers to keep the solution free of contamination.
• Remove contact lenses before use and wait at least 15 minutes before putting them back in.
• Keep track of how many days in a row you have used the drops — avoid more than about 3 consecutive days without checking with a pharmacist.
• Store the bottle upright and note the date you opened it, so you know when to discard it.
• Keep the bottle out of reach of young children, as accidental ingestion of eye drops of this type can cause serious effects in a small child.

Precautions: Use in pregnancy and breastfeeding should be discussed with a doctor or pharmacist first, as data on tetrahydrozoline and zinc sulfate eye drops in these situations is limited. This product should be used with particular caution, or avoided, in young children, since accidental ingestion of tetrahydrozoline-containing eye or nasal drops has been associated with serious effects in small children, including drowsiness and slowed heart rate — keep the bottle well out of children’s reach at all times. People with diagnosed glaucoma or other chronic eye conditions should check with an eye doctor before use.

When to See a Doctor or Pharmacist: Seek professional advice if eye redness or irritation does not improve within 72 hours, if you have eye pain, light sensitivity, discharge, or vision changes, or if you need to use redness-relieving drops repeatedly over several weeks, as this may indicate an underlying eye condition that needs proper assessment rather than ongoing self-treatment.
