| ==USE IN SPECIFIC POPULATIONS==
| |
| ===Pregnancy===
| |
| | |
| '''Pregnancy Category C'''
| |
| | |
| | |
| Reproduction studies have been performed in rabbits and rats at oral doses up to 1.5 (15 mg/kg/day) and 6 (60 mg/kg/day) times the human oral daily dose, respectively, and have revealed no evidence of teratogenicity. In the rat, however, this multiple of the human dose was embryocidal and retarded fetal growth and development, probably because of adverse maternal effects reflected in reduced weight gains of the dams. This oral dose has also been shown to cause hypotension in rats. There are no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed. Verapamil crosses the placental barrier and can be detected in umbilical vein blood at delivery.

| ===Labor and delivery===
| |
| | |
| It is not known whether the use of verapamil during labor or delivery has immediate or delayed adverse effects on the fetus, or whether it prolongs the duration of labor or increases the need for forceps delivery or other obstetric intervention. Such adverse experiences have not been reported in the literature, despite a long history of use of verapamil in Europe in the treatment of cardiac side effects of beta-adrenergic agonist agents used to treat premature labor.

| | |
| ===Nursing mothers===
| |
| | |
| Verapamil is excreted in human milk. Because of the potential for adverse reactions in nursing infants from verapamil, nursing should be discontinued while verapamil is administered.
| |
| | |
| ===Pediatric use===
| |
| | |
| Safety and effectiveness in pediatric patients have not been established.<ref name="dailymed.nlm.nih.gov">{{Cite web | last = | first = | title = CALAN (VERAPAMIL HYDROCHLORIDE) TABLET, FILM COATED [G.D.
