Authorities in Zambia have ordered a local manufacturer to stop the production and distribution of an energy drink that reportedly caused a prolonged erection in a man.
The move comes after the Uganda Bureau of Standards (UBS) said in a letter dated 4 January that it had tested samples from a bottle of Natural Power SX after a customer complained of constant sweating and an erection lasting nearly six hours.
UBS said the drink contained sildenafil citrate used to treat erectile dysfunction.
The drink is manufactured by Revin Zambia Limited, a company located in Ndola in the north of the country.
The company’s General Manager, Vikas Kapoor, told the BBC’s Newsday programme that to the best of his knowledge the energy drink does not contain any drugs.
