- Breast feeding: No studies have been conducted in humans to assess the impact of
PF-04691502 on milk production, its presence in breast milk and its effects on the
breast-fed child. Because drugs are commonly excreted in human milk and because of the
potential for serious adverse reactions in nursing infants, lactating female patients
are excluded from this study.

transit or absorption of the study drug, such as the inability to take oral medication
in tablet form and malabsorption syndrome.
