THURSDAY, Feb. 2 (HealthDay News) -- Be wary of buying the
cholesterol-lowering drugs known as statins on the Internet,
British researchers say.
Common statins such as Lipitor, Crestor or Zocor may not be the
same as advertised and sites often don't include warnings about
side effects or even require a prescription, the researchers
"A potential purchaser of statins in the U.K., where one can only legally receive them on a doctor's prescription, searching the web for product, is likely to encounter sites from a wide geographical base and of generally poor quality," said lead researcher David Brown, from the School of Pharmacy and Biomedical Sciences at the University of Portsmouth.
"Potentially, customers who obtain statins in this way, without their doctor's prescription, may not be aware of potential side effects and may put themselves in harm's way," he added.
The report was published Feb. 2 in the journal
Pharmacoepidemiology & Drug Safety.
For the study, Brown's team looked at 184 Internet sites
"Information necessary for safe use of the product was often poorly presented and in the majority of cases, incomplete," Brown said. "Where present, side effect information such as warnings, contraindications and possible side effects was in general, unstructured and unhelpful."
They found that more than 92 percent of these sites did not
include information on contraindications for statins. In addition,
another 47 percent didn't include information on drugs that
shouldn't be taken along with statins.
Moreover, up to 96 percent of the sites didn't include
information on adverse symptoms to watch out for, including
myopathy, liver disease, hypersensitivity and pancreatitis, the
Only 7 percent of the sites listed all known side effects and
only 65 percent described any side effects in lay language, they
Dr. Laurence Gardner, a professor of medicine and executive dean
for education and policy at the University of Miami Miller School
of Medicine, said that this is not really a problem in the United
"There are countries that let you buy statins without a medical exam or a prescription," Gardner said. "In this day and age, that's nuts."
In the United States, very high-potency generic statins are
available for $4 a month from big box stores, he said. "So, it's
inconceivable that you can buy them cheaper."
"Moreover, there are enough side effects from these drugs that it requires at least a modest amount of physician oversight," he said.
In addition, people taking statins need to have their
cholesterol monitored to be sure they are hitting target levels and
whether the dose of the drug needs to be adjusted, he said.
