There are limited data with the use of betaxolol eye drops in pregnant women. Epidemiological studies have not revealed malformative effects but show a risk for intrauterine growth retardation when beta-blockers are administered by the oral route. In animal reproductive studies, no drug-induced maternal toxicity or teratogenicity was observed at clinically relevant doses (see Data) . Because animal reproductive studies are not always predictive of human response, BETOPTIC S should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. In the U.S. general population, the estimated background risk of major birth defects is 2% to 4% and of miscarriage is 15% to 20% of clinically recognized pregnancies. Data Animal Data In a rat embryo-fetal development (EFD) study, oral administration of 4, 40, or 400 mg/kg/day betaxolol on gestational days 6 through 18, the period of organogenesis, resulted in marked embryo-fetal lethality, increased incidence of skeletal and visceral abnormalities, and decreased fetal weights at the maternally toxic dose of 400 mg/kg/day (7785 times higher than the maximum recommended human ophthalmic dose [MRHOD] of 0.0083 mg/kg/day, on a mg/m 2 basis). The no-observed-adverse-effect-level (NOAEL) for maternal or embryo-fetal toxicity was 40 mg/kg/day (778 times higher than the MRHOD, on a mg/m 2 basis). In a rabbit EFD study, oral administration of 1, 4, 12, and 36 mg/kg/day betaxolol on gestational days 6 through 18, the period of organogenesis, resulted in a marked increase in embryo-fetal lethality at 36 mg/kg/day (1400 times higher than the MRHOD, on a mg/m 2 basis). No maternal toxicity was reported in this study. In a perinatal and postnatal development study in rats, oral administration of 4, 32, and 256 mg/kg/day betaxolol during late gestation through lactation resulted in a marked decrease in offspring survival within 4 days postpartum at the highest dose (4982 times higher than the MRHOD, on a mg/m 2 basis). In surviving F 1 offspring, growth/development and reproductive function were also affected. The NOAEL was 32 mg/kg/day (623 times higher than the MRHOD, on a mg/m 2 basis). In a prenatal and postnatal development study in rats, an oral betaxolol dose of 150 mg/kg/day (2920 times higher than the MRHOD, on mg/m 2 basis) administered throughout the entire gestation period and lactation, resulted in maternal and developmental toxicity in F 1 offspring, including decreased offspring survival, body weight and growth/development and functional deficits in surviving offspring. No NOAEL for developmental or maternal toxicity was established in this study. Oral administration of 4, 32, and 256 mg/kg/day betoxolol to rats prior to mating and through late gestation, or until weaning, produced embryo-fetal lethality, neonatal mortality, decreased mean fetal weight, growth/development and functional deficits in surviving offspring at 256 mg/kg/day (4982 times higher than the MRHOD, on a mg/m 2 basis). At 32 mg/kg/day (623 higher than the MRHOD, on a mg/m 2 basis), decreased mean fetal weight on Gestation Day 20, and pup weight at birth and on Day 4 postpartum were observed. At 4 mg/kg/day (78 times higher than the MRHOD, on a mg/m 2 basis), a slight decrease in mean fetal weight was observed on Gestation Day 20."],"overdosage":["10 OVERDOSAGE No information is available on overdosage in humans.

( 1 )"],"warnings_and_cautions":["5 WARNINGS AND PRECAUTIONS Systemic Absorption : Same adverse reactions found with systemic administration of beta-adrenergic receptor inhibitors may occur with topical ophthalmic administration. ( 5.1 ) Cardiac Failure : Discontinue treatment at the first signs of cardiac failure. ( 5.2 ) Diabetes Mellitus : Beta-adrenergic receptor inhibitors may mask the signs and symptoms of acute hypoglycemia. Administer with caution in diabetic patients subject to hypoglycemia. ( 5.3 ) Thyrotoxicosis : Beta-adrenergic receptor inhibitors may mask certain clinical signs (e.g., tachycardia) or hyperthyroidism. ( 5.4 ) 5.1 Systemic Absorption As with many topically applied ophthalmic drugs, this drug is absorbed systemically. The same adverse reactions found with systemic administration of beta-adrenergic receptor inhibitors may occur with topical administration. For example, severe respiratory reactions and cardiac reactions, including death due to bronchospasm in patients with asthma, and death due to cardiac failure, have been reported with topical application of beta-adrenergic receptor inhibitors. 5.2 Cardiac Failure BETOPTIC S 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 S should be discontinued at the first signs of cardiac failure. 5.3 Diabetes Mellitus Beta-adrenergic receptor inhibitors should be administered with caution in patients subject to hypoglycemia or to diabetic patients (especially those with labile diabetes) who are receiving insulin or oral hypoglycemic agents. Beta-adrenergic receptor inhibitors may mask the signs and symptoms of acute hypoglycemia. 5.4 Thyrotoxicosis Beta-adrenergic receptor inhibitors may mask certain clinical signs (e.g., tachycardia) of hyperthyroidism. Patients suspected of developing thyrotoxicosis should be managed carefully to avoid abrupt withdrawal of beta-adrenergic receptor inhibitors, which might precipitate a thyroid storm. 5.5 Muscle Weakness Beta-adrenergic receptor inhibitors have been reported to potentiate muscle weakness consistent with certain myasthenic symptoms (e.g., diplopia, ptosis, and generalized weakness). 5.6 Surgical Anesthesia The necessity or desirability of withdrawal of beta-adrenergic receptor inhibitors prior to major surgery is controversial. Beta-adrenergic receptor inhibitors impair the ability of the heart to respond to beta adrenergically mediated reflex stimuli. This may augment the risk of general anesthesia in surgical procedures. Some patients receiving beta-adrenergic receptor inhibitors have experienced protracted, severe hypotension during anesthesia. Difficulty in restarting and maintaining the heartbeat has also been reported. In patients undergoing elective surgery, consider gradual withdrawal of beta-adrenergic receptor inhibitors. If necessary during surgery, the effects of beta-adrenergic receptor inhibitors may be reversed by sufficient doses of adrenergic agonists. 5.7 Bronchospasm and Obstructive Pulmonary Disease Caution should be exercised in the treatment of glaucoma patients with excessive restriction of pulmonary function. There have been reports of asthmatic attacks and pulmonary distress during betaxolol treatment. Although rechallenges of some such patients with ophthalmic betaxolol has not adversely affected pulmonary function test results, the possibility of adverse pulmonary effects in patients sensitive to beta-adrenergic receptor inhibitors cannot be ruled out. 5.8 Atopy/Anaphylaxis While taking beta-adrenergic receptor inhibitors, patients with a history of atopy or a history of severe anaphylactic reaction to a variety of allergens may be more reactive to repeated accidental, diagnostic, or therapeutic challenge with such allergens. Such patients may be unresponsive to the usual doses of epinephrine used to treat anaphylactic reactions. 5.9 Angle-Closure Glaucoma In patients with angle-closure glaucoma, the immediate treatment objective is to reopen the angle. This may require constricting the pupil. Betaxolol has little or no effect on the pupil and should not be used alone in the treatment of angle-closure glaucoma. 5.10 Vascular Insufficiency Because of potential effects of beta-adrenergic receptor inhibitors on blood pressure and pulse, these inhibitors should be used with caution in patients with vascular insufficiency. If signs or symptoms suggesting reduced cerebral blood flow or Raynaud’s phenomenon develop following initiation of therapy with BETOPTIC S, alternative therapy should be considered. 5.11 Bacterial Keratitis Bacterial keratitis may occur with use of multiple dose containers of topical ophthalmic products when these containers are inadvertently contaminated by patients who, in most cases, had a concurrent corneal disease or a disruption of the ocular epithelial surface.
