What you should do

  • Consult with your doctor if you have used this product and have health concerns
  • Report any adverse events to Health Canada.

Who is affected

Consumers who have bought or used Herberex.


Tadalafil should only be used under the supervision of a healthcare practitioner. Products containing tadalafil or its analogs (very similar substances) should never be used by individuals taking any kind of nitrate drug (e.g. nitroglycerine) as it can cause potentially life-threatening low blood pressure.

Individuals with heart problems including high blood pressure, a history of heart attack, stroke, abnormal heart beat or chest pain are at higher risk of cardiovascular side-effects if they engage in sexual activity. Other possible side-effects of using tadalafil include headache, facial flushing, indigestion, dizziness, abnormal vision and hearing loss.

Health Canada has not received any reports of adverse reactions involving Herberex.
