SildenafiloKrkacontains the active ingredient sildenafilo, which belongs to a group of medicines called phosphodiesterase type 5 (PDE5) inhibitors. It works by dilating the blood vessels in the penis, allowing blood to flow when sexually stimulated.Sildenafilo will only help you achieve an erection if you are sexually stimulated.

Sildenafilo is indicated for the treatment of erectile dysfunction in adult men, sometimes referred to as impotence. This occurs when a man is unable to obtain or maintain a firm, satisfactory erection for sexual activity.

Do not take Sildenafilo Krka:

• If you are allergic to sildenafil or any of the other components of this medication (listed in section 6).
• If you are taking certain medications called nitrates, as the combination may lead to a dangerous decrease in your blood pressure. Consult your doctor if you are taking any of these medications, which are often used to relieve chest pain (or "chest pain"). If you are unsure, consult your doctor or pharmacist.
• If you are using any of the medications called nitric oxide donors, such as amyl nitrite ("poppers"), as the combination may lead to a dangerous decrease in your blood pressure.
• If you are taking riociguat. This medication 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 caused by clots). PDE5 inhibitors, such as Sildenafilo Krka, have shown to increase the hypotensive effect of this medication. If you are taking riociguat or are unsure, consult your doctor.
• If you have a severe heart or liver problem.
• If you have recently experienced a stroke or heart attack or if you have low blood pressure.
• If you have a rare inherited eye disorder (such as retinitis pigmentosa).
• If you have previously experienced vision loss due to non-arteritic anterior ischemic optic neuropathy (NAION).
