Snafi is 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. Snafi has been shown to significantly improve the ability of obtaining a hard erect penis suitable for sexual activity.

Snafi contains the active substance tadalafil which belongs to a group of medicines called phosphodiesterase type 5 inhibitors. Following sexual stimulation Snafi 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. Snafi will not help you if you do not have erectile dysfunction.

It is important to note that Snafi 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.

Snafi 5 mg is used to treat adult men with urinary symptoms associated with a common condition called benign prostatic hyperplasia. This is when the prostate gland gets bigger with age. Symptoms include difficulty in starting to pass water, a feeling of not completely emptying the bladder and a more frequent need to pass water even at night. Snafi improves blood flow to, and relaxes the muscles of, the prostate and bladder which may reduce symptoms of benign

prostatic hyperplasia. Snafi has been shown to improve these urinary symptoms as early as 1-2 weeks after starting treatment.

Do not take Snafi

- If you are allergic (hypersensitive) to tadalafil or any of the other ingredients of Snafi (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”). Snafi 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 have had a recent heart attack within the last 90 days.

- If you have had a recent stroke within the last 6 months.

- If you have low blood pressure or uncontrolled high blood pressure.

- If you have 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 Snafi, have been shown to increase the hypotensive effects of this medicine. If you are taking riociguat or are unsure tell your doctor.
