Carmellose Sodium: Brands, Price & Uses in Bangladesh

Carmellose Sodium (also known as sodium carboxymethylcellulose) is primarily used as an ophthalmic lubricant.

Established / OTC monograph uses

• Dry eye symptoms (temporary relief): Carmellose Sodium ophthalmic solution is used for temporary relief of burning, irritation, and discomfort due to dryness of the eye.
• Ocular surface protectant: Carmellose Sodium acts as a protectant against further irritation and helps relieve dryness caused by exposure to wind or sun, or reduced blinking (e.g., prolonged screen use).

Other established uses (formulation-dependent)

• Oral/dental protective paste: In paste form, Carmellose Sodium is used as a protective coating over mouth ulcers, minor oral lesions, and denture-related sores.
• Bulk-forming laxative component: In some oral formulations, Carmellose Sodium is included as a bulk-forming agent to help relieve occasional constipation, usually as part of a combination fiber product.

Carmellose Sodium is not intended to treat the underlying cause of dry eye disease or to treat infection or inflammation of the eye.

Ophthalmic (dry eye relief)

Adults and children: Instill 1-2 drops of Carmellose Sodium ophthalmic solution into the affected eye(s) as needed, up to 4 times daily unless otherwise directed by a physician.

Oral/dental protective paste

Adults and children 12 years and older: Apply a thin layer of Carmellose Sodium paste directly to the affected area of the mouth 2-3 times daily, preferably after meals and at bedtime, until the lesion heals.

Bulk-forming laxative use

Adults: Follow the specific product's dosing instructions; Carmellose Sodium-containing bulk-forming products are typically taken with a full glass of water, one to three times daily.

See Use in Special Populations for pediatric and elderly considerations.

Carmellose Sodium is generally well tolerated. Reported adverse effects include:

• Ophthalmic use: Temporary blurred vision immediately after instillation, mild stinging or burning, and eye irritation. Preservative-containing formulations of Carmellose Sodium may cause more irritation with frequent, long-term use compared with preservative-free single-use vials.
• Oral/dental paste use: Local irritation or an unpleasant taste; rare hypersensitivity reactions.
• Oral bulk-forming use: Bloating, flatulence, or abdominal discomfort, particularly if fluid intake is inadequate.

Discontinue Carmellose Sodium and seek medical evaluation if eye pain, vision changes, or persistent irritation occurs (see Precautions and Warnings).
