Relating to the authority of pharmacists to furnish certain medications.

HB 845 allows pharmacists to provide prescription medications for certain acute conditions after performing specific simple lab tests, under a physician's written protocol. It directly affects pharmacists and patients seeking rapid treatment for conditions like strep throat (using rapid strep tests) or influenza (using rapid flu tests). The bill expands pharmacists' role by enabling them to dispense medications for these conditions without a full prescription, provided the test is a federally "waived" clinical laboratory test. This change applies only to acute, short-term illnesses identified through these specific tests, with the Texas Board of Pharmacy required to establish protocol standards. The bill does not alter existing prescription requirements for chronic conditions.
