Sympathomimetic drug that is topically used for treatment of nose or the eye. On last update no relevant published data related to breastfeeding were found. A small dose together with a low plama level of most nasal and ophthalmologic compounds make that a significant excretion into breast milk would be unlikely. Avoid high dosing and do not use for longer than 3 days: as an adrenergic agonist drug it could be absorbed and a cause of side effects (vascular hypertension or hypotension, irritability, heart arrhythmia) in both the mother and the infant. Long term maintained doses may decrease milk production.
