SINGAPORE – The Health Sciences Authority (HSA) issued a statement on Thursday (May 26) warning the public against consuming a product containing an ingredient used to treat erectile dysfunction after a man fell ill and was hospitalized.

Prime Kopi Pejuang 3 in 1, marketed online as a natural product containing ingredients that improve men’s sexual health, was found to contain undeclared high levels of tadalafil, a synthetic and potent medicinal ingredient.

“Tadalafil is a prescription drug used to treat erectile dysfunction and should only be taken under medical supervision. Improper use of tadalafil is dangerous and may increase the risk of serious side effects including heart attack, stroke strokes, palpitations, irregular heartbeat and priapism, HSA said in the release.

Priapism refers to painful and prolonged erections. This is a serious condition that can lead to penile tissue damage and permanent loss of potency if not treated immediately.

A man who consumed the coffee product was taken to hospital after experiencing body aches, chills, headaches and tightness around his jaw. Another buyer suffered from priapism for about four hours after taking the product.

HSA stated, “Individuals consuming the product according to the label directions (one sachet per day) could overdose more than 10 times the usual prescribed dose of tadalafil.”

After receiving feedback regarding two cases of adverse reactions, HSA conducted testing on the coffee product and found that advertised claims that it was “natural” and contained “herbal ingredients from high quality” were wrong.

The authority advised consumers who purchased the product to stop taking it immediately and seek medical attention if they feel unwell. He also urged consumers to be vigilant and exercise caution when buying products online, especially those that carry exaggerated claims and promise to deliver quick effects.

The product was sold on local e-commerce platforms, including Shopee and Lazada, and on Facebook. HSA worked with the platforms to remove the affected listings and issued warnings to sellers.

HSA said, “All sellers and suppliers should stop selling or supplying ‘Prime Kopi Pejuang 3 in 1’ immediately. HSA will not hesitate to take strong enforcement action against anyone selling and/or supplying products that were found to be adulterated with potent medicinal ingredients.”

Those who sell or supply these products are subject to prosecution and a conviction can result in imprisonment for up to two years and/or a fine of up to $10,000, the authority said.
