1. What Tadalafil Tablets are and what they are used for

Tadalafil Tablets are a treatment for adult men with erectile dysfunction. This is when a man cannot get, or keep a hard, erect penis suitable for sexual activity. Tadalafil Tablets has been shown to significantly improve the ability of obtaining a hard erect penis suitable for sexual activity.

Tadalafil Tablets contain the active substance tadalafil which belongs to a group of medicines called phosphodiesterase type 5 inhibitors. Following sexual stimulation Tadalafil Tablets works by helping the blood vessels in your penis to relax, allowing the flow of blood into your penis. The result of this is improved erectile function. Tadalafil Tablets will not help you if you do not have erectile dysfunction.

It is important to note that Tadalafil Tablets does not work if there is no sexual stimulation. You and your partner will need to engage in foreplay, just as you would if you were not taking a medicine for erectile dysfunction.

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

•    if you are allergic to tadalafil or any of the other ingredients of this medicine (listed in section 6)

•    if you are taking any form of organic nitrate or nitric oxide donors such as amyl nitrite. This is a group of medicines ("nitrates") used in the treatment of angina pectoris ("chest pain"). Tadalafil Tablets has been shown to increase the effects of these medicines. If you are taking any form of nitrate or are unsure tell your doctor

•    if you have serious heart disease or recently had a heart attack within the last 90 days

•    if you recently had a stroke within the last 6 months

•    if you have low blood pressure or uncontrolled high blood pressure

•    if you ever had loss of vision because of non-arteritic anterior ischemic optic neuropathy (NAION), a condition described as "stroke of the eye"

•    if you are taking riociguat. This drug 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 secondary to blood clots). PDE5 inhibitors, such as Tadalafil Tablets, have been shown to increase the hypotensive effects of this medicine. If you are taking riociguat or are unsure tell your doctor.
