The Singapore Food Agency (SFA) found three food products sold in Singapore containing medicinal substances not permitted for use in food and directed their immediate removal on August 4, 2026 [1, 2, 3].
The three products are B Solution Honey (Liquid) and Jus Tuan Haji 1921 from Malaysia, and Shaio-Ge Xian Li 365 S1 Botanical Beverage Mix Barley Seedling Powder from Taiwan [1, 2, 3]. B Solution Honey contained tadalafil, a prescription drug for erectile dysfunction, which the SFA warned poses serious health risks including heart attack, stroke, prolonged painful erections, and potentially life-threatening low blood pressure when combined with nitrates [1, 2, 3]. The agency said, "Tadalafil is a prescription medicine and should only be taken under medical supervision. Inappropriate use is dangerous and can increase the risk of serious adverse effects, including heart attack, stroke, irregular heartbeat and prolonged painful erections" [3].
Shaio-Ge Xian Li 365 S1 Botanical Beverage Mix contained sennosides, a laxative used to treat constipation. Prolonged use may cause abdominal pain, diarrhea, muscle weakness, dehydration, and lax bowel syndrome [1, 2, 3]. Jus Tuan Haji 1921 was found to contain dexamethasone, a steroid medicine which may cause side effects such as blurred vision, excessive hair growth, menstrual irregularities, Cushing's syndrome, and overdose symptoms including psychosis and electrolyte imbalance [1, 2, 3].
The SFA worked with sellers to remove all online listings and issued advisories to immediately cease sales of the products [1, 2, 3]. It advised consumers who purchased the products not to consume them and urged those feeling unwell after consumption to seek medical advice promptly [1, 2, 3]. The agency reminded consumers to exercise caution when buying food from unverified sources and to verify product claims before purchase [1, 3].
Following the August 4 directive, media outlets published detailed reports on August 5 about the SFA's findings and enforcement actions [2, 3].
