USE IN SPECIFIC POPULATIONS
8.1 Pregnancy
Pregnancy Category X.
Risk Summary BELVIQ is contraindicated during pregnancy, because weight loss offers no potential benefit to a pregnant woman and may result in fetal harm. Maternal exposure to lorcaserin in late pregnancy in rats resulted in lower body weight in offspring which persisted to adulthood. If this drug is used during pregnancy, or if the patient
Reference ID: 3151563
becomes pregnant while taking this drug, the patient should be apprised of the potential hazard of maternal weight loss to the fetus.
Clinical Considerations A minimum weight gain, and no weight loss, is currently recommended for all pregnant women, including those who are already overweight or obese, due to the obligatory weight gain that occurs in maternal tissues during pregnancy.
Animal Data
Reproduction studies were performed in pregnant rats and rabbits that were administered lorcaserin during the
period of embryofetal organogenesis. Plasma exposures up to 44 and 19 times human exposure in rats and rabbits,
respectively, did not reveal evidence of teratogenicity or embryolethality with lorcaserin hydrochloride.
In a pre- and postnatal development study, maternal rats were dosed from gestation through post-natal day 21 at 5, 15, and 50mg/kg lorcaserin; pups were indirectly exposed in utero and throughout lactation. The highest dose (~44 times human exposure) resulted in stillborns and lower pup viability. All doses lowered pup body weight similarly at birth which persisted to adulthood; however, no developmental abnormalities were observed and reproductive performance was not affected at any dose.
8.3 Nursing Mothers
It is not known whether BELVIQ is excreted in human milk. Because many drugs are excreted in human milk, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
8.4 Pediatric Use
The safety and effectiveness of BELVIQ in pediatric patients below the age of 18 have not been established and the use of BELVIQ is not recommended in pediatric patients.
8.5 Geriatric Use
In the BELVIQ clinical trials, a total of 135 (2.5%) of the patients were 65 years of age and older. Clinical studies of BELVIQ did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects, but greater sensitivity of some older individuals cannot be ruled out.
Since elderly patients have a higher incidence of renal impairment, use of BELVIQ in the elderly should be made on the basis of renal function [see Use in Specific Populations (8.6) and Clinical Pharmacology (12.3)]. Elderly patients with normal renal function should require no dose adjustment.
8.6 Renal Impairment
No dose adjustment of BELVIQ is required in patients with mild renal impairment. Use BELVIQ with caution in patients with moderate renal impairment. Use of BELVIQ in patients with severe renal impairment or end stage renal disease is not recommended [see Clinical Pharmacology (12.3)].
8.7 Hepatic Impairment
Dose adjustment is not required for patients with mild hepatic impairment (Child-Pugh score 5-6) to moderate hepatic impairment (Child-Pugh score 7-9). The effect of severe hepatic impairment on lorcaserin was not

evaluated. Use lorcaserin with caution in patients with severe hepatic impairment [see Clinical Pharmacology (12.3)].
