Description
Overview of the medicine
Tearon Fresh 1% Eye Drop is an ophthalmic lubricant used to relieve dryness and irritation of the eyes. It helps to moisten the eyes, providing comfort and protection from environmental irritants.
Uses & Indications
Dosage
Adults
Instill 1 or 2 drops in the affected eye(s) as needed, 3-4 times daily, or as directed by a physician.
Elderly
Same as adult dosage.
Renal_impairment
No dosage adjustment necessary.
How to Take
For ophthalmic use only. Tilt head back, pull down the lower eyelid to form a pouch, and instill the prescribed number of drops. Do not touch the dropper tip to any surface to avoid contamination.
Mechanism of Action
Carboxymethylcellulose Sodium acts as an artificial tear by increasing the viscosity of the tear film and lubricating the surface of the eye. It forms a protective layer on the eye, mimicking natural tears to reduce friction and provide moisture.
Pharmacokinetics
Onset
Within minutes of administration.
Excretion
Not excreted systemically in significant amounts. Cleared from the ocular surface primarily through blinking and tear turnover.
Half life
Not applicable due to minimal systemic absorption and local action.
Absorption
Minimal systemic absorption occurs after topical ophthalmic administration due to its high molecular weight. Primarily acts locally on the ocular surface.
Metabolism
Not significantly metabolized systemically.
Side Effects
Contraindications
- Hypersensitivity to carboxymethylcellulose sodium or any component of the formulation.
Drug Interactions
Other eye drops
If using other ophthalmic medications, wait at least 5-10 minutes between applications to avoid washing out the previous drop.
Storage
Store at room temperature (below 30°C). Protect from light. Do not freeze. Keep out of reach of children.
Overdose
Overdose is unlikely to cause systemic toxicity due to minimal systemic absorption. If accidentally swallowed, seek medical advice.
