A 33-YEAR-OLD man is being investigated by the Health Sciences Authority (HSA) for selling sexual enhancement products containing potent chemicals that could cause serious health problems.
The five products were sold online, the HSA said yesterday.
Among them, the StarkRx Performance Enhancer, Maximum Strength Sexual Enhancer and Forta Plus for Men contained either the prescription substance, sildenafil - the generic name for Viagra - or nortadalafil - a substance associated with another drug for erectile dysfunction, Cialis.
They were advertised as containing only natural herbal ingredients.
These prescription drugs have serious side effects and should be used under a doctor's guidance. Sildenafil is also unsuitable for patients with certain heart-related problems, who are on medications containing nitrates.
A fourth product, Stark-Rx, also contained dangerous substances.
The fifth, Stud 100 Male Genital Desensitizer Spray, was found to contain exceedingly high concentrations of lignocaine, an anaesthetic. It could cause dizziness and low blood pressure.
The products were detected through HSA's ongoing surveillance of Internet sales activities.
Some Singapore consumers may have bought the products online.
The HSA has not received any reports of adverse reactions associated with the products, but it said: "Consumers should be aware that illegal health products are generally produced under poor manufacturing conditions with no quality control.
"The contents of these products can also vary from batch to batch, which can cause serious health hazards."
Gleneagles Hospital urologist Peter Lim said many men buy products on recommendations from their friends.
"They believe their friends," he said. "But their body conditions differ, or they may be taking medicine that should not be taken with these drugs."
Anyone taking the flagged products should stop immediately and see a doctor if they feel unwell, HSA said.
