Carcinogenesis, Mutagenesis, Impairment of Fertility

Levocabastine was not carcinogenic in male or female rats or in male mice when administered in the diet for up to 24 months. In female mice, levocabastine doses of 5,000 and 21,500 times the maximum recommended ocular human use level resulted in an increased incidence of pituitary gland adenoma and mammary gland adenocarcinoma possibly produced by increased prolactin levels. The clinical relevance of this finding is unknown with regard to the interspecies differences in prolactin physiology and the very low plasma concentrations of levocabastine following ocular administration.

Mutagenic potential was not demonstrated for levocabastine when tested in Ames' Salmonella reversion test or in Escherichia coli, Drosophila melanogaster, a mouse Dominant Lethal Assay or in rat Micronucleus test.

In reproduction studies in rats, levocabastine showed no effects on fertility at oral doses of 20 mg/kg/day (8,300 times the maximum recommended human ocular dose).

Pregnancy

Nursing Mothers

Based on determinations of levocabastine in breast milk after ophthalmic administration of the drug to one nursing woman, it was calculated that the daily dose of levocabastine in the infant was about 0.5 µg.

Pediatric Use

Safety and effectiveness in pediatric patients below the age of 12 have not been established.

Levocabastine is a potent, selective histamine H₁- antagonist. Antigen challenge studies performed two and four hours after initial drug instillation indicated activity was maintained for at least two hours.

In an environmental study, LIVOSTIN™ 0.05% (levocabastine hydrochloride ophthalmic suspension) instilled four times daily was shown to be significantly more effective than its vehicle in reducing ocular itching associated with seasonal allergic conjunctivitis.

After instillation in the eye, levocabastine is systemically absorbed. However, the amount of systemically absorbed levocabastine after therapeutic ocular doses is low (mean plasma concentrations in the range of 1-2 ng/ mL).

LEVOCABASTINE - OPHTHALMIC

(lee-voh-cab-AST-een)

COMMON BRAND NAME(S): Livostin

USES: This medication is used to relieve eye symptoms (itching, redness, eyelid swelling, watering) due to seasonal allergies. Levocabastine belongs to a class of drugs known as antihistamines. It works by preventing the effects of a certain natural chemical (histamine).

This drug is not recommended for use in children younger than 12 years unless directed by the doctor.

HOW TO USE: To apply eye drops, wash your hands first. To avoid contamination, do not touch the dropper tip or let it touch your eye or any other surface.

If you are wearing contact lenses, remove them before using eye drops. Wait at least 15 minutes before replacing your contact lenses.

Use this medication usually 2 times a day or as directed by your doctor. Your doctor may then direct you to use this medication 3 to 4 times a day. Shake the bottle before each application. Tilt your head back, look upward, and pull down the lower eyelid to make a pouch. Hold the dropper directly over your eye and place 1 drop into the pouch. Look downward and gently close your eyes for 1 to 2 minutes. Place one finger at the corner of your eye (near the nose) and apply gentle pressure. This will prevent the medication from draining out. Try not to blink and do not rub your eye. Repeat these steps for your other eye.

Do not rinse the dropper. Replace the dropper cap after each use.

If you are using another kind of eye medication (e.g., drops or ointments), wait at least 5 to 10 minutes before applying other medications. Use eye drops before eye ointments to allow the drops to enter the eye.

Tell your doctor if your condition persists or worsens after 3 days.

SIDE EFFECTS: Eye discomfort or headache may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.
