Sildenafilo Kern Pharma belongs to a group of medicines called phosphodiesterase type 5 (PDE5) inhibitors. It works by dilating the blood vessels of the penis, allowing blood to flow when sexually stimulated. Sildenafilo Kern Pharma will only help you get an erection if you are sexually stimulated. Do not take Sildenafilo Kern Pharma if you do not have erectile dysfunction. The use of Sildenafilo Kern Pharma is not indicated in women.

Sildenafilo Kern Pharma is indicated for the treatment of male erectile dysfunction, sometimes called impotence. This occurs when a man cannot obtain or maintain a firm, adequate erection for satisfactory sexual activity.

Do not take Sildenafilo Kern Pharma

• If you are taking certain medications called nitrates, as the combination may cause a potentially dangerous drop 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 cause a potentially dangerous drop in your blood pressure.
• If you are allergic (hypersensitive) to sildenafilo or to any of the other components of Sildenafilo Kern Pharma.

Some patients taking an alpha-blocker, a medication used to treat high blood pressure or prostate hypertrophy, may experience dizziness or lightheadedness caused by a drop in blood pressure when sitting or standing up quickly.
