Last updated on Jan 25, 2023. 0115-9811-01, DLIS are present in up to half of all neonates and in varying percentages of pregnant women, patients with hypertrophic cardiomyopathy, patients with renal or hepatic dysfunction, and other patients who are volume-expanded for any reason. Thus, the amount of digoxin ingested daily by the infants is estimated to be between 0.03 to 0.16 mcg/kg/day. The following are some of the side effects that can be associated with digoxin. Updated Digoxin showed no genotoxic potential in in vitro studies (Ames test and mouse lymphoma). In general, the adverse reactions of digoxin tablets are dose-dependent and occur at doses higher than those needed to achieve a therapeutic effect. Digoxin is primarily excreted by the kidneys; therefore, patients with impaired renal function require smaller than usual maintenance doses of digoxin [ see Dosage and Administration (2.3) ]. Fetal/neonatal adverse reactions Digoxin has been shown to cross the placenta and is found in amniotic fluid. Newborn infants display considerable variability in their tolerance to digoxin. Tell your doctor if you are pregnant, plan on getting pregnant, or are breast-feeding.

Correct factors that may be contributing to the adverse reactions [see Warnings and Precautions (5)]. Hypocalcemia can nullify the effects of digoxin in humans; thus, digoxin may be ineffective until serum calcium is restored to normal. This is followed by a much more gradual decline in the serum concentration of the drug, which is dependent on the elimination of digoxin from the body. causes increased availability of intracellular calcium in the myocardium and conduction system, with consequent increased inotropy, increased automaticity, and reduced conduction velocity, indirectly causes parasympathetic stimulation of the autonomic nervous system, with consequent effects on the sino-atrial (SA) and atrioventricular (AV) nodes, reduces catecholamine reuptake at nerve terminals, rendering blood vessels more sensitive to endogenous or exogenous catecholamines, increases baroreceptor sensitization, with consequent increased carotid sinus nerve activity and enhanced sympathetic withdrawal for any given increment in mean arterial pressure, increases (at higher concentrations) sympathetic outflow from the central nervous system (CNS) to both cardiac and peripheral sympathetic nerves. When switching from intravenous to oral digoxin formulations, make allowances for differences in bioavailability when calculating maintenance dosages (see Table 6).
