Sizodon LS (risperidone/trihexyphenidyl) and Uvox (fluvoxamine) can pass into breast milk. While fluvoxamine is generally considered relatively safe during breastfeeding, risperidone and trihexyphenidyl require careful consideration as they can cause sleepiness in your baby or potentially decrease your milk supply. Waiting four hours helps reduce the medication level in your milk, but because you are taking a combination, please consult your doctor and pediatrician. They will help monitor your healthy six-month-old for any drowsiness or feeding changes, keeping you both safe and supported.
