NASHVILLE (AP) — Beginning this month, prescriptions for opioid pain medicines and benzodiazepine medicines may not be dispensed in Tennessee in quantities that exceed a 30-day supply.

The new limits apply to anyone dispensing the drugs. That includes pharmacies, dispensaries and mail-order programs located outside the state.

According to the Tennessee Department of Health, some of the drugs limited under the new law are Lortab, Oxycontin, Percocet, Xanax and Valium.

For Schedule II medicines, each 30-day supply requires a new prescription. For other drugs, a single prescription can be refilled in 30-day increments for up to six months.

The new law is part of a statewide effort to reduce prescription drug abuse.
