"April 24, 2014 -- As many as 4 in 10 Americans have sneezing, runny nose, and watery eyes due to allergies. If you're one of them, allergy shots can help ease your reaction to the plants, insects, or animals that trigger your symptoms. But they r"...
Information for Patients: To prevent contaminating the dropper tip and solution, care should be taken not to touch the eyelids or surrounding areas with the dropper tip of the bottle. Keep the bottle tightly closed when not in use. Do not use if the solution has become discolored.
Patients should be advised not to wear a contact lens if their eye is red. EMADINE ® (emedastine difumarate ophthalmic solution) 0.05% should not be used to treat contact lens related irritation. The preservative in EMADINE ® (emedastine difumarate ophthalmic solution) 0.05%, benzalkonium chloride, may be absorbed by soft contact lenses. Patients who wear soft contact lenses and whose eyes are not red, should be instructed to wait at least ten minutes after instilling EMADINE ® (emedastine difumarate ophthalmic solution) 0.05% before they insert their contact lenses.
Carcinogenesis, Mutagenesis, Impairment of Fertility
Emedastine difumarate demonstrated no carcinogenicity effects in lifetime studies in mice and rats at dietary doses more than 80,000 times and more than 26,000 times the maximum recommended ocular human use level of 0.002 mg/kg/day for a 50 kg adult, respectively. Higher dose levels were not tested. Emedastine difumarate was determined to be nonmutagenic in an in vitro bacterial reverse mutation (Ames) test, an in vitro modification of the Ames test, an in vitro mammalian chromosome aberration test, an in vitro mammalian forward mutation test, an in vitro mammalian DNA repair synthesis test, an in vivo mammalian sister chromatid exchange test and an in vivo mouse micronucleus test. There was no evidence of impaired fertility or reproductive capacity in rats at 15,000 times the maximum recommended ocular human use level.
Pregnancy: Pregnancy Category B
Teratology and peri- and post-natal studies have been conducted with emedastine difumarate in rats and rabbits. At 15,000 times the maximum recommended ocular human use level, emedastine difumarate was shown not to be teratogenic in rats and rabbits and no effects on peri/post-natal development were observed in rats. There are, however, no adequate and well controlled studies in pregnant women. Because animal studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed.
Emedastine has been identified in breast milk in rats following oral administration. It is not known whether topical ocular administration could result in sufficient systemic absorption to produce detectable quantities in breast milk. Nevertheless, caution should be exercised when EMADINE (emedastine difumarate ophthalmic solution ) is administered to a nursing mother.
Safety and effectiveness in pediatric patients below the age of 3 years have not been established.
No overall differences in safety or effectiveness have been observed between elderly and younger patients.
