As one of the most widely available and frequently purchased treatments for erectile dysfunction, Sildenafil prices can vary quite a lot. Over 140 million men suffer from this problem worldwide for both physical and psychological reasons but millions of them trust Sildenafil, the active ingredient in Viagra, to help them achieve and maintain an erection. It is designed to increase blood flow to the penis alongside arousal to aid a longer-lasting and more rigid erection and is an affordable solution to erectile dysfunction and impotence.
Sildenafil functions with your mood and only works when you are aroused. Before sex, signals are sent from the brain through the central nervous system and certain chemicals in the walls of the penis are activated. One chemical called cGMP causes more blood to flow and be delivered, which engorges the penis. Phosphodiesterase type-5 is the enzyme that works to block this effect when the body feels it is time. Sildenafil is a phosphodiesterase type-5 inhibitor and the effect is that the blood vessels are free to widen and allow in as much blood as necessary for a stronger and more resilient erection. The effects can last for several hours, ready to work only when you are in the mood and most agree that the sildenafil citrate price is well worth the payoff.
ED treatment online and without prescription
Some men report Sildenafil taking effect in as little as 15 minutes, but taking a dose between 30 minutes and four hours before sex is the average procedure. Sildenafil is rapidly absorbed by the body with or without food but eating large quantities of fatty foods can slow the rate at which it is absorbed. It is also safe to take every day, but you should not take it more than once in 24 hours. Doses can be 25 mg, 50 mg or 100 mg.
There are few side effects from taking a Sildenafil tablet, but headache, nasal congestion and dizziness have been reported. These are easily combated but you should always contact a doctor if you experience any adverse side effects to taking Sildenafil. It should be avoided if you are taking any other phosphodiesterase type-5 inhibitors to treat erectile dysfunction and care should be exercised with other medications. Sildenafil can affect your blood pressure, so you should not take it if you also take nitrates, such as for heart conditions. It is also advised that you do not drink grapefruit juice whilst taking Sildenafil.
Of course, Sildenafil does not protect against any sexually transmitted diseases, such as HIV. Sildenafil cost will vary depending on where you purchase it.
