Suggestions to reduce infant exposure include taking the single dose just before the infant's longest sleep period or feeding the infant stored human milk or formula for 24 to 36 hours after the single (or last) dose. The manufacturer recommends women should not breastfeed on the day of praziquantel treatment and during the subsequent 72 hours.
