Clinical Studies Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

Ocular: In clinical trials, the most frequent event associated with the use of BETAXON™ (levobetaxolol hydrochloride ophthalmic suspension) Ophthalmic Suspension 0.5% has been transient ocular discomfort upon instillation (11%). Transient blurred vision has been reported in approximately 2% of patients. Other ocular events have been reported in less than 2% of patients and include: cataracts, and vitreous disorders.

Systemic: Systemic reactions following administration of BETAXON™ (levobetaxolol hydrochloride ophthalmic suspension) Ophthalmic Suspension 0.5% and other topical ocular formations of betaxolol have been at an incidence of less than 2%. These include:

Central Nervous System: Anxiety, dizziness, hypertonia, and vertigo.

Digestive: Constipation and dyspepsia.

In a three-month, multi-center, double-masked, active-controlled trial in pediatric patients, the adverse event profile of BETAXON™ (levobetaxolol hydrochloride ophthalmic suspension) Ophthalmic Suspension was comparable to that seen in adult and elderly patients.
