UK Drugs in Lactation Advisory Service

Antidepressants

  • Individual maternal and infant situations must be taken into account before any drug is prescribed for the mother.
  • In general, all drugs should be avoided in premature or low birth weight infants, or in those who have any underlying conditions.
  • If a drug is prescribed, it should be at the lowest practical dose and for the shortest time.

Drugs classified with '?' should be used with caution and only after an assessment of benefit to the mother versus risk, real or potential, to the infant. These drugs either have insufficient clinical data on their use in lactation to regard as absolutely safe or they have had minor, reversible side effects reported in a breast-fed infant.
