New York City-based Amazon has ordered tens of thousands of prescription opioid painkillers, including several from a drugmaker that has been at the center of a congressional investigation.
In a letter to customers, Amazon says it will pay a fee of $25 per order to Amazon Pharmacy.
The company says it is making the payments to make sure its drug supply is available to its customers.
The move comes as lawmakers investigate whether Amazon is misleading customers about the risk of addiction and whether it improperly promoted its own drugs.
The company said it will reimburse patients up to $200 for the drug they purchased.
The Federal Trade Commission has been investigating Amazon’s opioid painkiller prescriptions for months and has said that drugmakers must provide information to patients about the risks and benefits of drugs they use.
Amazon has faced criticism for using an alias to hide the drug maker.
