"Dec. 18, 2012 -- Taking aspirin regularly appears to slightly raise the risk of the eye condition known as age-related macular degeneration or AMD, new research suggests.
The increased risk only occurred with people who had taken aspi"...
No data are available regarding overdosage in humans. Should accidental ocular overdosage occur, flush eye(s) with water or normal saline. If accidentally ingested, efforts to decrease further absorption may be appropriate (gastric lavage). The most common signs and symptoms to be expected with overdosage with administration of a systemic beta-adrenergic blocking agent are symptomatic bradycardia, hypotension, bronchospasm, and acute cardiac failure. Should these symptoms occur, discontinue BETAGAN® (levobunolol) therapy and initiate appropriate supportive therapy. The following supportive measures should be considered:
- Symptomatic bradycardia: Use atropine sulfate intravenously in a dosage of 0.25 mg to 2 mg to induce vagal blockade. If bradycardia persists, intravenous isoproterenol hydrochloride should be administered cautiously. In refractory cases, the use of a transvenous cardiac pacemaker should be considered.
- Hypotension: Use sympathomimetic pressor drug therapy, such as dopamine, dobutamine or levarterenol. In refractory cases, the use of glucagon hydrochloride may be useful.
- Bronchospasm: Use isoproterenol hydrochloride. Additional therapy with aminophylline may be considered.
- Acute cardiac failure: Conventional therapy with digitalis, diuretics and oxygen should be instituted immediately. In refractory cases, the use of intravenous aminophylline is suggested. This may be followed, if necessary, by glucagon hydrochloride, which may be useful.
- Heart block (second or third degree): Use isoproterenol hydrochloride or a transvenous cardiac pacemaker.
BETAGAN® (levobunolol) ophthalmic solution is contraindicated in those individuals with bronchial asthma or with a history of bronchial asthma, or severe chronic obstructive pulmonary disease (see WARNINGS); sinus bradycardia; second and third degree atrioventricular block; overt cardiac failure (see WARNINGS); cardiogenic shock; or hypersensitivity to any component of these products.
