Tear Drops (Carboxymethylcellulose sodium)

Tear Drops (Carboxymethylcellulose Sodium)

Generic Name:

Carboxymethylcellulose Sodium

Brand Name:

Tear Drops (commonly marketed under various brand names)

Drug Class:

Ophthalmic Lubricant / Artificial Tears

Description:

Tear Drops containing Carboxymethylcellulose sodium are ophthalmic solutions formulated to provide lubrication to the eyes. Carboxymethylcellulose sodium is a water-soluble cellulose derivative that mimics natural tears by moisturizing the ocular surface, improving tear film stability, and providing symptomatic relief from dry eyes.

These artificial tears are widely used to relieve discomfort caused by dry eye syndrome (keratoconjunctivitis sicca), irritation from environmental factors, or extended screen use. Through the formation of a protective layer on both the cornea and conjunctiva, tear Drops aid in reducing dryness of the eyes and irritation, as well as burning, itching, and the appearance of redness.

Indications:

Tear Drops (Carboxymethylcellulose Sodium) are indicated for the temporary relief of:

• Dry eyes, irritation, and dryness caused by inadequate natural tear production
• Burning, stinging, and discomfort caused by exposure to wind, sun, or air conditioning
• Eye irritation caused by dust, smoke, or prolonged contact lens wear
• Post-surgical eye dryness or irritation
• Computer vision syndrome (eye strain from prolonged digital device use)

Dosage and Administration:

• Dosage: Apply 1-2 drops to the affected eye(s), depending on the need, generally 3-4 times per day. If the dryness is severe, it is possible that more frequent usage may be needed.
• Route: Ophthalmic (eye drops)
• Instructions:
  • Cleanse your hands before using.
  • Then tilt the head and draw down the lower eyelid until it forms tiny pockets.
  • The prescribed number of drops is in your pocket.
  • Keep your eyes closed and refrain from the habit of blinking or rubbing.
  • Remove any excess liquid using an unclean tissue.
  • Don’t touch the tip of the dropper to surfaces or your eyes to keep it from getting contaminated.
  • Replace cap after use.

Mechanism of Action:

Carboxymethylcellulose sodium is a high molecular weight, viscous polymer that enhances tear viscosity and stabilizes the tear film. It functions as a lubricant and a protective substance by:

• Conserving water in the surface of the eye
• Eliminating the loss of natural tears
• Protection of corneal and conjunctival epithelial cells from damage and irritation
• Reduces eye discomfort and improves ease

Pharmacokinetics:

As a topical ophthalmic preparation, Carboxymethylcellulose sodium acts locally with minimal systemic absorption. It’s cleared off the surface of the eye mainly through tears draining via the nasolacrimal duct.

Contraindications:

• Known hypersensitivity or allergy to Carboxymethylcellulose sodium or any component of the formulation
• Be cautious if the eye is infected. Artificial tears are not able to help treat eye inflammations.

Warnings and Precautions:

• Contamination Risk: Beware of contaminating the tip of the dropper. Drops that are contaminated can cause eye infection.
• Contact Lens Use: Discard contact lenses before use unless the product has been labeled as safe to use with lenses. Make sure to wait at least 15 mins before reinserting the lenses.
• Eye Pain or Vision Changes: Do not use the medication and consult an eye doctor if inflammation, pain, swelling, or vision changes are observed.
• Preservatives: Certain products contain preservatives, which can cause allergic or irritation reactions when used for a long period of time. It is best to avoid preservatives for regular use.

Side Effects:

Common Side Effects:

• The vision may be blurred temporarily following the instillation
• Mild eye irritations, or there is a burning sensation when applied

• Pregnancy: Most commonly, it is considered safe to use it only as required.
