What is Tadalafil used for?

Patient Info Service - information for patients

1. What Tadalafil Mylan is and what it is used for

Tadalafil Mylan is used to treat adult men with erectile dysfunction. This occurs when a man cannot get or maintain a hard, erect penis for sexual activity. Tadalafil showed marked improvement in getting a hard, erect penis for sexual activity.

Tadalafil Mylan contains the active substance tadalafil and belongs to a group of medicines called "phosphodiesterase 5 inhibitors". After sexual stimulation, Tadalafil Mylan helps relax the blood vessels in your penis, allowing blood to flow into your penis. The result is an improved erection. Tadalafil Mylan will not help you if you do not have erectile dysfunction.

It is important to note that without sexual stimulation, tadalafil will not work. Foreplay in partnership may be necessary, just as if you had not taken an erectile dysfunction medicine.

2. What you need to know before you take Tadalafil Mylan.

Do not take Tadalafil Mylan if you:

- are allergic to tadalafil or any of the other ingredients of this medicine (listed in section 6).

  • are taking any form of organic nitrates or nitric oxide donors such as amyl nitrite. This is a group of medicines (“nitrates”) used to treat angina (a type of “heart pain”). Tadalafil has been shown to increase the effects of these medicines. If you are taking any form of nitrates or are unsure, talk to your doctor.

  • have severe heart disease or have had a heart attack in the past 90 days.

  • have had a stroke in the past 6 months.

  • have low or uncontrolled high blood pressure.

  • have ever had vision loss due to non-arteritic anterior ischemic optic neuropathy (NAION), this disorder is described as "stroke of the eye".

  • Take riociguat. This medicine is used to treat pulmonary arterial hypertension (i.e. high blood pressure in the lungs) and chronic thromboembolic pulmonary hypertension (i.e. high blood pressure in the lungs in addition to blood clots). PDE5 inhibitors, such as Tadalafil Mylan, have been shown to increase the blood pressure lowering effects of this medicine. If you are taking riociguat or are unsure, talk to your doctor.
