Description
Viagra is a prescription only medication that contains the active drug Sildenafil. Viagra is a Phosphodiesterase Type 5 inhibitor (PDE 5), which works by increasing the blood flow to the penis. It achieves this by relaxing the blood vessels in your penis, and is therefore a vasodilator. Viagra will help to achieve and maintain an erection when you are sexually excited or stimulated. Viagra 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. Viagra 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 Viagra can last for up to 4 to 5 hours. Viagra can take up to 30 minutes for the effects to start to be seen. Viagra is available in various strengths of 25mg, 50mg and 100mg. If you have not tried Viagra before, it is recommended to try the 25mg strength tablet first.
Viagra is the most popular treatment 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.
