FORTY instant beverages sold by foreign traders have been found to contain harmful substances like sildenafil, tadalafil, vardenafil and sibutramine, which can be fatal if taken without a doctor's advice, reported Berita Harian.
The daily reported that most of the products were found to have been mixed with substances normally used as sex stimulants or for slimming purposes.
These products were packed at illegal factories in the country, it said.
"The use of sex stimulants such as sildenafil, tadalafil and vardenafil without a doctor's advice can bring serious side effects, including low blood pressure, and users will feel dizzy or may even faint after consuming these products," it added.
The daily reported that the use of a slimming drug like sibutramine might also affect the nerves and attack other organs, which could cause mental and psychosis problems, and if it was mixed with nitrate in other drugs, it might have cardiovascular effects and cause a heart attack.
The paper quoted Health Ministry pharmaceutical services division senior assistant director of enforcement Mazlan Ismail as saying that there were two types of instant drinks.
They are original products that are safe to consume and "erotic" drinks that have been mixed with active chemical substances.
Mazlan said instant beverages that had been mixed with these substances were sold for up to RM5 (S$2) a packet compared with original drinks that cost between RM1 ($0.40) and RM1.50 (S$0.60) per packet.
He also urged consumers to stop buying or taking these products.
A survey showed that these banned products were still being sold at several places like in Jalan Raja Bot and Jalan Chow Kit.
