GlaxoSmithKline weight loss drug could be sold over the counter

GlaxoSmithKline’s weight loss drug Xenical (orlistat) could soon be available without prescription in the US.

The US Food and Drink Administration (FDA) is to decide today whether the drug in a low dose form should be available, meaning it would be the first ever non-prescription weight loss drug approved in the US.

Sales of the drug have been lower than expected due to some side effects, but the company claims that lower doses of Xenical reduce the level of side effects.

Xenical, which GlaxoSmithKline has the licence to market in the US from Roche, works by preventing fat being absorbed into the body.

The company is also suggesting it be taken with vitamins to ensure there is no chance of vitamin deficiencies occurring while it is being taken.

There are also concerns that Xenical may block the intake of other drugs, especially those used in treating diabetes.
