Undeclared Drug Ingredients Found In Sexual Dysfunction Managing Product
The Hong Kong Department of Health (DH) appealed to people not to buy or use a product called "Zhuang Tjar Gere" for managing sexual dysfunction.
A spokesman for the department said the product was found to have contained undeclared drug ingredients that may cause serious side effects.
He said the department received a report concerning a 79-year-old man who fainted and injured his chest on October 25. He was admitted to Yan Chai Hospital on October 29 and was discharged on November 15.
Investigation revealed that he had taken the above product, which was brought from shops in Tsuen Wan, about six hours before the onset of symptom.
Government Laboratory test results today confirmed the product remnant contained sildenafil and tadalafil which are usually used for treating male sexual dysfunction.
The spokesman noted that the product is neither a registered pharmaceutical product nor proprietary Chinese medicine in Hong Kong. There is no record of this product having been imported into Hong Kong.
DH officers inspected 44 medicine shops in Tsuen Wan but no such product was located.
The spokesman said side effects of sildenafil and tadalafil included low blood pressure, headache, vomiting, dizziness, and transient vision disturbances. They may interact with nitrates found in some prescription drugs (such as nitroglycerin) and may lower blood pressure of patients to dangerous levels.
Under the Pharmacy and Poisons Ordinance, products containing any of these ingredients must be registered before sale and can be sold only on a doctor's prescription and under supervision of a pharmacist.
People who have bought the product are advised not to take them. They are urged to seek advice from their doctors if feeling unwell after consuming the product.
They should destroy and dispose of the products or submit them to the department's Pharmaceutical Service at 3/F, Public Health Laboratory Centre, 382 Nam Cheong Street, Kowloon, during office hours. If they have any enquiry, there is a hotline number 2572 2068 which operates during office hours.
The spokesman urged people who had a problem of sexual dysfunction to consult healthcare professionals for appropriate advice if necessary.
