Regimens: Drug Samples Found to Affect Spending
Having doctors distribute free samples of medicines may do exactly what drug companies hope for — encourage patients to spend more money on drugs.
A study in the April issue of Medical Care found that patients who never received free samples spent an average of $178 for six months of prescriptions. Those receiving samples spent $166 in the six months before they obtained free medicine, $244 when they received the handouts and $212 in the six months after that.
Researchers studied 5,709 patients, tracking medical histories and drug expenditures; 14 percent of the group received free samples. The study adjusted for prior and current health conditions, race, socioeconomic level and other variables.
The authors acknowledge that the study results could be partly explained by unmeasured illness in the group given samples.
The lead author, Dr. G. Caleb Alexander, an assistant professor of medicine at the University of Chicago, said although free samples might save some patients money, there were other ways to economize. “Using more generics, prescribing for three months’ supply rather than one month’s and stopping drugs that may no longer be needed can also save money,” Dr. Alexander said.
