Tearlasts Uses, Dosage, Side Effects, Food Interaction and all others data.
The higher strength of Carboxymethylcellulose Sodium USP-NF provides long-lasting relief from dryness by forming a soothing gel after administration of the drops on to the eyes.
In a randomized clinical study of patients with mild or moderate forms of eye dryness, ophthalmic treatment with sodium carboxymethylcellulose resulted in a diminished frequency of symptoms compared to the placebo group . Carboxymethylcellulose interacts with human corneal epithelial cells to facilitate corneal epithelial wound healing and attenuate eye irritation in a dose-dependent manner . It exhibits protective actions on the ocular surface in various applications; it mediates cytoprotective effects on the ocular surface when applied prior to contact lenses and reduces the incidence of epithelial defects during LASIK .

Uses
Carboxymethylcellulose Sodium is used as a lubricant to relieve irritation and discomfort due to dryness of the eye or due to exposure to wind or sun.
Tearlasts is also used to associated treatment for these conditions: Dry Eyes, Ocular Irritation
How Tearlasts works
Carboxymethylcellulose binds to the surface of corneal epithelial cells via its glucopyranose subunits binding to glucose receptors GLUT-1 . The residence time of carboxymethylcellulose bound to corneal cells is approximately 2 hours as indicated by a short-term binding assay . Binding of carboxymethylcellulose to the matrix proteins stimulated corneal epithelial cell attachment, migration, and re-epithelialization of corneal wounds .

Pregnancy & Breastfeeding use
Use in Pregnancy: There is no data on the use of Carboxymethylcellulose Sodium 1% during pregnancy and lactation in human. Animal studies did not show harmful effects with the active ingredient Carboxymethylcellulose Sodium. Use in Lactation: Carboxymethylcellulose Sodium is not absorbed systemically; there is no known potential for excretion in human breast milk.
Pediatric use: The safety and effectiveness in pediatric patients have not been established.
Contraindication
Contraindicated in patients who are hypersensitive to any of the components of Carboxymethylcellulose Sodium.
Special Warning
Use in children: No information available.
Use in elderly patients: No information available.
Acute Overdose
Since CMC is pharmacologically inert and not expected to be absorbed systemically, systemic effects from topical overdose are not expected from the administration of Carboxymethylcellulose sodium (Cellufresh) 0.5%. Additionally, no toxic side effects are expected should accidental systemic overdose occur.
Storage Condition
Store in a cool, dry place and protect from light. Keep out of the reach of children.
