Discuss your health with your doctor to ensure that you are healthy enough for sex. Sildenafil/Tadalafil can cause a drop in blood pressure which may cause dizziness and, in rare cases, loss of consciousness. Do not operate heavy machinery until you know how Sildenafil/Tadalafil affects you. Although rare, serious side effects can occur and include chest pain or pressure, palpitations, shortness of breath, impaired mental status or mentation, erections lasting 4 or more hours, and changes in vision or hearing. If you experience any of these, it is recommended that you go to the emergency room or call 911 immediately.
Sildenafil and Tadalafil can cause serious side effects. Rare but serious side effects include:
- An erection that will not go away (priapism). If you have an erection that lasts more than 4 hours, get medical help right away. If it is not treated right away, priapism can permanently damage your penis.
- Sudden vision loss in one or both eyes. Sudden vision loss in one or both eyes can be a sign of a serious eye problem called non-arteritic anterior ischemic optic neuropathy (NAION). Stop taking Sildenafil and call your healthcare provider right away if you have any sudden vision loss.

- Low blood pressure. Some individuals may experience low blood pressure after using Sildenafil. While this will typically cause dizziness, in extreme cases, it could lead to loss of consciousness and other serious and life-threatening complications. If you have high or low blood pressure, take medications that can affect blood pressure, or have a history of heart attack, stroke, or transient ischemic attack (TIA), you should consult with your primary care doctor before taking Sildenafil.
