The Pharmaceutical Administration Bureau (ISAF) warned residents in a statement on Wednesday against using a natural virility product named “The Goat Sublingual Strip”*, which has been found to contain the prescription-only Western drug ingredient “Sildenafil”.
According to the statement, the bureau took action after receiving Wednesday’s warning from the Hong Kong Department of Health (DH) concerning the virility product.
Sildenafil is commonly used to treat male erectile dysfunction; the side effects may include low blood pressure, headache, vomiting, dizziness, and temporary blurred vision, the statement said, adding that the product may also interact with certain medications, such as nitroglycerin, potentially causing blood pressure to drop to dangerous levels and posing serious health risks.
The statement urged residents to stop buying or using the product right away, adding that the bureau will closely monitor the circulation of the product in Macau, aiming to safeguard public health.
If residents have already purchased the product, they should cease using it at once and submit it to the bureau for disposal, the statement said.
For any enquiries, please contact the ISAF Monitoring Department on 8598 3233 during office hours.
