Monitoring 1 and 2 hours after administration (dosing) includes the following:

  • Blood pressure check
  • Heart rate check (hold dose for heart rate at
  • Blood glucose level (because of the potential for blocking of liver glycogen phosphorylase) only for inpatients; recommended that young infants feed every 3-4 hours to decrease risk of hypoglycemia
  • Temperature determination to evaluate for hypothermia
  • Observation for bronchospasm
  • </ul>

    At home, parents should observe for signs of lethargy, poor feeding, and/or bronchospasm.

    Blood pressure and heart rate should be evaluated intermittently at the pediatrician's office.

    Note that practices vary considerably.


    Consider a gradual taper over 2 weeks, rather than abrupt discontinuation. Cardiac hypersensitivity may occur 24-48 hours after propranolol is discontinued (peaks at 4-8 d).
