Neotear0.5%+0.9%

Neotear is an over-the-counter ophthalmic lubricant (artificial tears) with an established, well-recognized use:

• Dry eye syndrome: Symptomatic relief of burning, stinging, itching, and irritation caused by dryness of the eye.
• Ocular exposure irritation: Temporary relief of eye discomfort due to exposure to wind, sun, or other environmental irritants.
• Lubrication as a protectant: Used as an ocular lubricant to protect the eye against further irritation, including for adjunctive comfort during reduced or incomplete blinking.

Neotear does not treat the underlying cause of dry eye and is intended only for symptomatic relief.

Each mL of Carboxymethyl Cellulose + Glycerin ophthalmic solution typically contains Carboxymethylcellulose Sodium (a viscosity-enhancing polymer, commonly 0.5%) and Glycerin (a demulcent/humectant, commonly 0.9%), formulated as a sterile isotonic ophthalmic solution. Strengths may vary slightly by brand; always check the product label.

Neotear is a fixed-dose combination ophthalmic lubricant used as artificial tears. Carboxymethylcellulose sodium is a viscosity-enhancing polymer that increases the thickness and residence time of the tear film on the ocular surface, while glycerin is a demulcent and humectant that helps attract and retain moisture. Together they form a lubricating, protective film over the surface of the eye, providing symptomatic relief of dryness, irritation, and discomfort. Neotear is available as a sterile ophthalmic solution (eye drops) and is widely used as a first-line, non-prescription treatment for mild to moderate dry eye symptoms.

Neotear belongs to the therapeutic class of ophthalmic lubricants / artificial tear preparations (demulcents), used for the symptomatic management of dry eye and ocular surface irritation.

Carboxymethyl Cellulose + Glycerin works through complementary, purely physical (non-pharmacologic) mechanisms:

• Carboxymethylcellulose sodium: A hydrophilic polymer that increases the viscosity of the tear film, prolonging its residence time on the ocular surface, stabilizing the tear film, and reducing evaporation.
• Glycerin: A humectant/demulcent that draws and holds water at the ocular surface, providing an additional lubricating and moisturizing effect.

The combination coats the cornea and conjunctiva with a smooth, lubricating film that reduces friction from blinking and relieves the sensation of dryness. Systemic absorption of Carboxymethyl Cellulose + Glycerin after topical ocular application is negligible.

Neotear is for topical ophthalmic (eye) use only. Instill directly into the conjunctival sac of the affected eye(s), avoiding contact of the dropper tip with the eye or any surface to prevent contamination. Not for injection or oral use.

No clinically significant drug-drug interactions have been well established for Neotear, owing to its topical route of administration and minimal systemic absorption.

• Other topical ophthalmic products: If using more than one eye medication, space administration by at least 5-10 minutes to prevent one product from diluting or washing out another, and to avoid altering the intended effect of prescription eye medications (e.g., glaucoma drops).
• Contact lenses: Some preservatives in certain formulations may interact with soft contact lens material; see Precautions and Warnings.

Neotear is generally very well tolerated, as it acts only at the ocular surface with minimal systemic absorption. Reported side effects are typically mild and transient:

• Temporary blurred vision immediately after instillation
• Mild, transient eye irritation, stinging, or burning
• Eye discomfort or a foreign-body sensation
• Rarely, ocular redness or watering

Persistent eye pain, marked vision changes, or worsening redness are not expected effects and should prompt discontinuation and medical review (see Precautions and Warnings).

Neotear has minimal to negligible systemic absorption when used as directed for topical ophthalmic use, and is generally considered acceptable for use during pregnancy and lactation. However, as with any medicine, it should be used only if clearly needed, and a physician or pharmacist should be consulted before use during pregnancy or breastfeeding, particularly for prolonged or frequent use.

Before and during use of Neotear, observe the following precautions:

• Contact lenses: Remove contact lenses before instillation unless the specific product is labeled as safe for use with contact lenses in place.
• Duration of use: Discontinue use and consult a physician if eye pain, changes in vision, continued redness or irritation of the eye, or if the condition worsens or persists for more than 72 hours.
• Contamination: To avoid contamination, do not touch the dropper tip to any surface, including the eye. Replace the cap after each use. Discard the product per the labeled discard period after opening (commonly within 1 to 3 months, per product labeling).
• Appearance change: Do not use if the solution changes color or becomes cloudy.
• Underlying eye disease: Not a substitute for evaluation of underlying causes of persistent dry eye or red eye; seek medical advice for unresolved or recurrent symptoms.

Ocular overdose with Neotear is unlikely to cause serious harm due to minimal systemic absorption; excess instillation may simply be rinsed out with clean water. If accidentally ingested by mouth, especially by a child, or if a severe or unexpected reaction occurs, seek immediate medical attention or contact a poison control center/emergency services rather than attempting home treatment.

Store at room temperature (below 30°C), away from light and moisture. Keep the cap tightly closed and avoid contaminating the dropper tip. Keep out of reach of children. Discard the bottle after the period specified on the label following first opening.

Pediatric patients: Neotear may be used in children under the direction of a physician; safety and efficacy for unsupervised pediatric use have not been separately established, so parental/caregiver supervision is advised.

Elderly patients: No specific dose adjustment is needed; dry eye is common in this population and Neotear is commonly used for symptom relief.

Renal/hepatic impairment: No dose adjustment is required given the negligible systemic absorption of Neotear with topical ophthalmic use.

Contact lens wearers: See Precautions and Warnings regarding lens removal before use.

Neotear may be used as needed for as long as symptoms of dryness or irritation persist. If there is no improvement, or if symptoms worsen or persist beyond 72 hours of regular use, discontinue and seek medical advice, as an alternative diagnosis or treatment may be required.

Carboxymethyl Cellulose + Glycerin is classified under Ophthalmic Preparations, specifically as an Artificial Tear/Ocular Lubricant (Demulcent) combination.

Carboxymethyl Cellulose + Glycerin acts by physical, non-pharmacologic mechanisms at the ocular surface: carboxymethylcellulose sodium increases tear film viscosity and residence time, while glycerin acts as a humectant to attract and retain moisture, together forming a stabilizing, lubricating film that reduces friction and relieves dryness and irritation.

Neotear can be used in children when instillation of eye lubricant is needed, generally under adult supervision or physician direction. Because systemic absorption is negligible, the safety profile in children is expected to be similar to that in adults; however, formal pediatric efficacy/safety studies establishing specific labeling for all pediatric age groups are limited, so use in young children should be supervised by a caregiver or guided by a physician, particularly for frequent or prolonged use.
