The state of Georgia plans to use a compounding pharmacy to get the drug needed for an execution scheduled for next week.

A Department of Corrections spokeswoman on Thursday confirmed that the state will get pentobarbital from a compounding pharmacy for the execution of Warren Lee Hill, which is set for Monday.

The state's supply of pentobarbital expired in March. It has become increasingly difficult for states to get the drug because the manufacturer has said it doesn't want it used in executions.

Compounding pharmacies custom-mix small batches of a drug for specific clients. They've come under scrutiny after a deadly meningitis outbreak linked to contaminated injections made by a Massachusetts specialty pharmacy.

The FDA considers compounding pharmacy products unapproved drugs, and does not verify their safety or effectiveness.
