Sildenafil is a drug that is used to cure erectile dysfunction or male impotency. Some people think that this is natural problem that occurs when one is growing old though this is not true because erectile dysfunction can also affect young men even the teenagers. Sildenafil works together with sexual stimulation. Generally it helps in blocking the enzyme PDE -5 in your body. When this enzyme is blocked, the body muscles relax and allow more blood to flow to different parts of the body including the penis. With more blood flowing into the penis and less being released, the penis enlarges and becomes hard which in turn leads to an erection.

Sildenafil is only meant to be used by men who are suffering from erectile dysfunction because it only targets the penis. Women are also restricted from taking it. Note that Sildenafil is not a hormone therefore it only works when you are sexually stimulated and it cannot prevent you from contracting sexually transmitted diseases. Before using Sildenafil, it is advised that you go through the prescription that comes with it and also contact your doctor just to ensure that you know how it works, its dosage and what it treats. It is important to follow strictly the prescription and incase of any missed dose do not take it together with another to avoid any serious problem.

Sildenafil is taken through the mouth at least sixty seconds or sixty minutes before having sex. It is also advised that you completely avoid high fat foods because fats reduce Sildenafil effectiveness and you may not achieve the best results from it. The patients who take alcohol should also avoid it or take very low amounts of alcohol while under sildenafil medication. Remember that your Sildenafil dosage depends on your response to therapy, other medications that you are currently on and your medical conditions among others. This is why you must consult your doctor before you begin this medication.

Just like in other drugs, Sildenafil also has its side effects that occur differently to different users. Its side effects include facial flushing, vision changes, heartburn, stomach upset, nasal stuffiness, headache, dizziness, diarrhea and dizziness. When Sildenafil is over used, one can completely loose his vision. Other users have reported blurred vision and sensitivity to light. If the side effects become more serious or when they persist it is advised that you call your doctor immediately. The ones who have heart problems may be subjected to strain in the heart while having sex. If this happens or when you realize any discomfort while having sex it is advised that you stop immediately and consult your doctor.

Most of the Sildenafil side effects are normally mild and they can be treated easily. Sildenafil also has some serious side effects such as severe nausea, severe headache, fainting and chest pain. At times you can experience an erection that last for a long period. In case of such problems, you have to consult your doctor immediately.
