Weight-loss hopefuls beware, two products which have been sold on the New Zealand market have been found to contain prescription drugs.
At least one person had suffered an "adverse event" which could be attributed to one of the weight-loss products, Medsafe said. The person noticed an increased heart rate and a laxative effect over time while taking the product.
The medicines regulator issued a warning and recall notice over Go Lean Detox and Go Detox after they were found to contain sibutramine and phenolphthalein.
In 2010, nations worldwide withdrew sibutramine after it was discovered it was associated with an increased risk of heart attacks and strokes. New Zealand followed suit.
Meanwhile, phenolphthalein contains a known laxative effect but is no longer used in medicines in New Zealand.
