Amlodipine Levels and Effects while Breastfeeding

Summary of Use during Lactation

Limited information indicates that maternal use of amlodipine during breastfeeding has not caused any adverse effects in breastfed infants. However, until more data become available, an alternate drug may be preferred.

Drug Levels

Maternal Levels. Relevant published information was not found as of the revision date.

Infant Levels. A preterm infant of 32 weeks gestation was breastfed exclusively from day 7 to day 20 postpartum. The infant's mother was taking amlodipine and labetalol in unspecified dosages for hypertension. After 4 days of breastfeeding, the infant's blood amlodipine level was unmeasurable (lower limit of assay not specified).[1]

Effects in Breastfed Infants

A woman took amlodipine for hypertension 5 mg daily beginning 2 weeks postpartum. Her exclusively breastfed infant was examined regularly and at 3 months of age was healthy and had normal physical and neurological development.[2]

One woman received amlodipine 2.5 mg orally twice daily during pregnancy for hypertension associated with glomerulonephritis. The dose was increased to 5 mg twice daily on day 2 postpartum. Her exclusively breastfed infant's growth was normal throughout the first year of life and no adverse effects were noted.[3]

A preterm infant of 32 weeks gestation was breastfed exclusively from day 7 to day 20 postpartum. The infant's mother was taking amlodipine and labetalol in unspecified dosages for hypertension. The infant had apnea episodes unrelated to amlodipine. Growth at 2 months of age was slightly low.[1]
