Included as part of the PRECAUTIONS section.

Single Patient Use Only

Do not use this container for more than one patient since NAVSTEL® (balanced salt ophthalmic solution) Solution does not contain a preservative.

Diabetes

Studies suggest that intraocular irrigating solutions which are iso-osmotic with normal aqueous fluids should be used with caution in diabetic patients undergoing vitrectomy since intraoperative lens changes have been observed.

Nonclinical Toxicology

Carcinogenesis, Mutagenesis, Impairment of Fertility

The carcinogenic potential of NAVSTEL® (balanced salt ophthalmic solution) Solution has not been investigated. The hypromellose in NAVSTEL (balanced salt ophthalmic solution) ® has been demonstrated to be non-mutagenic in the in vitro Ames assay and the bacterial reverse mutation assay. A similar modified cellulose polymer (methylcellulose) was also non-mutagenic at concentrations up to 5,000 mg/kg in the rat bone marrow cytogenic assay. Fertility studies have not been conducted with hypromellose; however, rats fed a diet of up to 5% methylcellulose had no significant adverse effects relative to reproductive function.
