Sibutramine was previously used to treat obesity but is no longer authorized for sale in Canada because of its association with an increased risk of cardiovascular side effects such as heart attack and stroke. Other side effects include increased blood pressure and heart rate, dry mouth, difficulty sleeping and constipation.

Sildenafil and Tadalafilare prescription drugs used to treat erectile dysfunction. Sildenafil and Tadalafil should not be used by individuals taking any kind of nitrate drug (e.g., nitroglycerine) as they can cause potentially life-threatening low blood pressure.
