Questions & Answers
Side Effects & Adverse Reactions
Topically applied beta-adrenergic blocking agents may be absorbed systemically. The same adverse reactions found with systemic administration of beta-adrenergic blocking agents may occur with topical administration. For example, severe respiratory reactions and cardiac reactions, including death due to bronchospasm in patients with asthma, and rarely death in association with cardiac failure, have been reported with topical application of beta-adrenergic blocking agents.
BETOPTIC® Ophthalmic Solution has been shown to have a minor effect on heart rate and blood pressure in clinical studies. Caution should be used in treating patients with a history of cardiac failure or heart block. Treatment with BETOPTIC Ophthalmic Solution should be discontinued at the first signs of cardiac failure.

Uses
BETOPTIC Ophthalmic Solution has been shown to be effective in lowering intraocular pressure and is indicated in the treatment of ocular hypertension and chronic open-angle glaucoma. It may be used alone or in combination with other anti-glaucoma drugs.
In clinical studies BETOPTIC was safely used to lower intraocular pressure in 47 patients with both glaucoma and reactive airway disease who were followed for a mean period of 15 months. However, caution should be used in treating patients with severe reactive airway disease or a history of asthma.

The recommended dose is one to two drops of BETOPTIC Ophthalmic Solution in the affected eye(s) twice daily. In some patients, the intraocular pressure lowering responses to BETOPTIC Ophthalmic Solution may require a few weeks to stabilize. As with any new medication, careful monitoring of patients is advised.
If the intraocular pressure of the patient is not adequately controlled on this regimen, concomitant therapy with pilocarpine and other miotics, and/or epinephrine and/or carbonic anhydrase inhibitors can be instituted.
