Description
Sildenafil is a prescription only medication that is the generic form of the branded Sildenafil tablet Viagra. Sildenafil is a Phosphodiesterase Type 5 inhibitor (PDE 5), which works by increasing the blood flow to the penis. Sildenafil is a vasodilator, so relaxes the blood vessels around the penis to allow for freer flow of blood to the area. Sildenafil should be taken before engaging in sexual activity, as it will help to achieve and maintain an erection when you are sexually excited or stimulated. Sildenafil is an effective treatment for men suffering from Erectile Dysfunction, when a man struggles to get and/or maintain a hard erection during sexual activity. Sildenafil will only work to help achieve and maintain an erection if you are sexually excited or stimulated after the medication has taken effect.
The effects of Sildenafil can take 30-60 minutes to be seen and the effects will last for around 4-6 hours. The time before effects are seen and length of effects are different from person to person. Sildenafil is available in various strengths of 25mg, 50mg and 100mg. If you have not tried Sildenafil before, it is recommended to try the 25mg strength tablet first.
Sildenafil is the most popular medication available for Erectile Dysfunction, but other available medications may be better suited to your needs. Cialis (Tadafil) has a longer duration of action than other treatments, and can last for up to 36 hours. Levritra (Vardenafil) can last for around 5 hours, and only takes 15 minutes for the effects to be seen. Vardenafil is also a more suitable treatment for people suffering from diabetes.
