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.
