In 1998, the Food and Drug Administration (FDA) approved Actiq, a potent narcotic, for use only in cancer patients who suffer intense bouts of pain that other narcotics don’t relieve.
But recent studies have shown cancer doctors account for only one percent of the thousands of Actiq prescriptions filled at retail pharmacies in the United States. Data gathered between June 2005 and October 2006 even suggests that more than 80 percent of patients who use the drug do not have cancer.
Instead, doctors are prescribing it “off label” for nonapproved uses, including headaches or back pain.
The FDA prohibits pharmaceutical companies from marketing their drugs for off-label use because, while off-label prescribing isn’t illegal, it is dangerous. Especially for a drug like Actiq.
Actiq contains fentanyl, a highly addictive substance that is 80 times as potent as morphine. The Drug Enforcement Administration (DEA) classifies fentanyl as a Schedule II substance, meaning it has the highest potential for abuse and associated risk of fatal overdose, and puts the substance in the same category as opium, cocaine and methamphetamine.
The drug acts quickly, providing relief within 15 minutes of consuming the fentanyl lozenge.
Actiq has been associated with the following adverse events:
- 127 deaths, including two children who confused the drug for candy
- 47 overdoses or other misuse
- 91 serious, nonfatal incidents, ranging from respiratory distress to severe dehydration
Cephalon Inc., Actiq’s maker based in Pennsylvania, said it does not market the drug for unapproved uses. While acknowledging that the drug is widely used off-label, Cephalon said it cannot control how doctors prescribe the drug.
The company, however, has sent representatives to a broad range of doctors, including sports-medicine specialists and family practitioners, to pitch the drug. It also gave these doctors dozens of coupons for free samples that patients can trade in for six Actiq sticks.
The United States attorney’s office in Philadelphia said it is investigating Cephalon’s marketing practices in connection with Actiq.
