Pregnancy-Lactation
Pregnancy
Limited published data from randomized controlled trials, case-controlled trials, and case series do not report a clear association with sildenafil and major birth defects, miscarriage, or adverse maternal or fetal outcomes when sildenafil is used during pregnancy; there are risks to mother and fetus from untreated pulmonary arterial hypertension
Pregnant women with untreated pulmonary arterial hypertension are at risk for heart failure, stroke, preterm delivery, and maternal and fetal death
Lactation
Limited published data from a case report describe presence of sildenafil and its active metabolite in human milk; there is insufficient information about effects of sildenafil on breastfed infant and no information on effects of sildenafil on milk production; limited clinical data during lactation preclude a clear determination of risk of drug to an infant during lactation

Mode of Action
Sibutramine produces its therapeutic effects by inhibition of norepinephrine (NE), serotonin (5-hydroxytryptamine, 5-HT), and to a lesser extent, dopamine reuptake at the neuronal synapse. By inhibiting the reuptake of these neurotransmitters, sibutramine promotes a sense of satiety and decrease in appetite, thereby reducing food intake.
