According to the Health Sciences Authority (HSA), 4 S Lion Juice products were found to contain substances that are used to treat erectile dysfunction. Consumers of this local brand of "organic orange juice" may be put at risk of heart attack, stroke or loss of hearing or vision, or even death due to the side effects of such drugs.
One of the S Lion products named S Lion Juice 10 gm contains tadalafil, the active ingredient in Cialis - a prescription drug used to treat male erectile dysfunction.
The other three drinks had chemically related compounds of this drug or sildenafil which is sold as Viagra.
HSA says: "These products carried claims such as 'increase energy and stamina', 'improve sleep quality', 'improve brain functionality', 'strengthen bones, prevent osteoporosis', and 'help menopausal women regain their emotional health and strength'."
The claims are unproven however, says the HSA. It added that these drugs are "not suitable for women and certain men, including those under 18 years of age, and patients with heart-related problems or who are on heart medications such as nitrates".
There have been reports in other countries of deaths in men who take such drugs while also taking nitrates to treat heart problems.
The HSA urges anyone who has bought these juices to stop taking them immediately and to see a doctor if they do not feel well.
It added: "HSA is currently investigating the sellers of these illegal products and will take strong enforcement actions against individuals who engage in the sale and supply of health products containing undeclared medicinal ingredients."
