Health Canada has issued an advisory about a locally-made male sexual enhancement product.
The warning tells customers to stop using the product, Harmony, right away.
"It was authorized as a natural health product, but Health Canada testing found it contains high levels of a prescription erectile dysfunction drug, tadalafil," says the advisory.
Apparently, this drug should only be given out under doctor's orders because of risky interactions with other medications and potential side effects.
"In Canada, the maximum dosage authorized in prescription tadalafil for erectile dysfunction is 20 mg per dose. Harmony samples were found to contain approximately three times that amount per capsule," the advisory continued.
The potential side effects of tadalafil include headache, dizziness, abnormal vision and even hearing loss.
The effects can be much more severe for people with heart problems and the list includes things like heart attacks and strokes.
Health Canada seized the products from three stores in British Columbia and advised a fourth to pull them from their shelves immediately.
If you use or own Harmony, Health Canada says to "stop using this product and seek medical advice if you have taken this product and have health concerns."
