SINGAPORE: The Health Sciences Authority (HSA) on Thursday (Dec 4) warned members of the public not to consume four illegal sexual enhancement products, which contain potent undeclared chemical ingredients.
The four products – Mr Zack Powerbro, Sparta X, Magic Penis and unlabelled dark green capsules – were tested to contain undeclared ingredients including prescription medicine sildenafil, which is used in the treatment of male impotence, the press release stated.
Mr Zack Powerbro and Sparta X were sold through the Internet, with the former touted for men’s health. Sparta X and Magic Penis claimed to maintain male stamina and improve sexual performance, respectively, HSA stated, adding that the unlabelled dark green capsules were packaged in blister packs without indicating the name of the product, ingredients or strength.
HSA’s laboratory tests found the four products to contain sildenafil and various analogues (chemically-related compounds) of sildenafil, including propoxyphenyl hydroxyhomosildenafil, propoxyphenyl aildenafil, propoxyphenyl thiohydroxyhomosildenafilpropoxyphenyl thioaidenafil and propoxyphenylsildenafil.
It stated: “The safety profiles of the various chemical ingredients are unknown. These chemicals may be more toxic than the original compound, sildenafil.
“Sildenafil is a potent prescription medicine used to treat male erectile dysfunction and should only be used under medical supervision. The inappropriate use of sildenafil can potentially cause serious adverse reactions, including decreased or loss of vision and hearing, low blood pressure, strokes and heart attacks,” the agency added.
It also said sildenafil is not suitable for patients with medical conditions such as some heart-related problems or who are on heart medications such as nitrates. Deaths have been reported overseas in patients found to be using sildenafil while on nitrates, it said.
HSA said it will take strong enforcement actions against individuals who engage in the sale and supply of health products containing undeclared medicinal ingredients. Anyone found to contravene the Poisons Act or Medicines Act faces a penalty of up to S$10,000 and/or imprisonment for a period of up to two years.
