The legal status of anabolic steroids varies from country to country. In the ., anabolic steroids are listed as Schedule III controlled substances under the Controlled Substances Act , which makes the possession of such substances without a prescription a federal crime punishable by up to seven years in prison.

However, possession is not punishable, a consequence reserved for schedule I, II or III substances. Those guilty of buying or selling anabolic steroids in Canada can be imprisoned for up to 18 months. Importing or exporting anabolic steroids also carry similar penalties.  Anabolic steroids are also illegal without prescription in Australia,  Argentina, Brazil, and Portugal,  and are listed as Schedule 4 Controlled Drugs in the United Kingdom.
The manufacturer recommends that Chinese patients taking lipid-modifying doses of niacin-containing products (>= 1 g/day niacin) should not receive the 10/80 mg dose of ezetimibe;simvastatin due to increased risk for myopathy and caution should be used when treating these patients with doses of simvastatin higher than 20 mg/day. In a double-blind, randomized cardiovascular outcomes trial, there was an increased incidence of myopathy in Chinese patients compared with non-Chinese patients taking ezetimibe; simvastatin 10/40 mg coadministered with lipid-modifying doses of niacin-containing products. Because the risk of myopathy is dose-related with simvastatin, the dose should be limited this population. It is unknown if this increased risk of myopathy observed in Chinese patients applies to other Asian patients.
