Requires prescriptions for certain patients to include patients' weight.

This bill requires prescriptions for patients under 18 years old to include the patient's weight in kilograms. It applies directly to healthcare providers issuing prescriptions for minors and mandates this information be written on the prescription form itself. The requirement covers all medications prescribed by authorized prescribers and takes effect 180 days after enactment. The bill does not change treatment protocols but adds weight documentation as a standard prescription element for pediatric care.
