Warnings
Contraindications
Asthma, uncompensated CHF, any beta-blocker side effects, COPD, sinus bradycardia, 2°/3° AV block, hypersensitivity
Cardiogenic shock or with overt cardiac failure not adequately compensated (eg, treated with cardiac glycosides &/or diuretics)
Cautions
Caution on inadequate cardiac function, latent cardiac insufficiency, cerebrovascular insufficiency, sick sinus syndrome, peripheral vascular disease, history of psychiatric illness, heart failure, diminished pulmonary function, nonallergic bronchospasm, diabetes mellitus, myasthenia gravis
Ophthalmic beta-blockers may impair compensatory tachycardia and increase risk of hypotension
Patients receiving topical levobunolol & a systemic ß-adrenergic blocking agent concomitantly should be observed carefully for potential additive effects on IOP &/or systemic effects of ß-adrenergic blockade
May mask signs of hyperthyroidism (ie, tachycardia)
May potentiate syndromes associated with vascular insufficiency (i.e. Raynaud’s phenomenon); use with caution
Choroidal detachment after filtration procedures reported with administration of aqueous suppressant therapy
Preservative benzalkonium chloride may be absorbed by soft contact lenses; patients wearing soft (hydrophilic) contact lenses should be instructed to remove contact lenses before administration of the solution and wait at least 15 minutes after instilling therapy before reinserting soft contact lenses
Use with a miotic in angle-closure glaucoma
Pregnancy & Lactation
Pregnancy
There are no adequate and well-controlled studies in pregnant women; ophthalmic solution should be used during pregnancy only if potential benefit justifies potential risk to fetus
Lactation
It is not known whether drug is excreted in human milk; systemic beta-blockers and topical timolol maleate are known to be excreted in human milk; exercise caution when administered to a nursing woman
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology

LEVOBUNOLOL - OPHTHALMIC
(lee-voe-BYOO-noe-lole)
COMMON BRAND NAME(S): Betagan
USES: This medication is used alone or with other medications to treat high pressure inside the eye due to glaucoma (open-angle type) or other eye diseases (such as ocular hypertension). Lowering high pressure inside the eye helps to prevent blindness. Levobunolol belongs to a class of drugs known as beta blockers and works by decreasing the amount of fluid production within the eye.
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.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 one drop into the pouch as directed by your doctor, usually once or twice daily. 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 if so directed or if your dose is for more than 1 drop.Do not rinse the dropper. Replace the dropper cap after each use.If you are using another kind of eye medication (such as drops or ointments), wait at least 5 to 10 minutes before using the other medications. Use eye drops before eye ointments to allow the eye drops to enter the eye.Use this medication regularly in order to get the most benefit from it. To help you remember, use it at the same time(s) each day. Keep using this medication even if you feel well. Most people with glaucoma or high pressure in the eyes do not feel sick.
SIDE EFFECTS: Temporary burning/stinging of the eye, itchy/red eyes, headache, or dizziness may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects.
