Filling the penis with blood causes an erection of the penis. For this to happen there is a serious of chemical reactions that occur when the man is sexually stimulated that direct the blood vessels accordingly. The blood vessels allowing blood into the penis increase in size and the blood vessels taking blood away decrease in size thus allowing the erection to be maintained. There is a chemical released after sexual activity that causes the opposite effect, allowing the blood to flow out of the penis and the erection to end. Viagra destroys this chemical, allowing for a prolonged engorgement of the penis with blood and a more sustained erection.
Viagra tablets that are available on prescription or to buy online in the UK are to be swallowed whole with some water about 1 hour prior to sexual activity. The amount of time it will take to work varies from person to person, but on average it takes between 20 minutes to 1 hour. Within a 4 to 6 hour period after taking a tablet an erection should occur if sexually stimulated. It can be taken with or without food, although if taken after a heavy meal it may take longer to work. Small amounts of alcohol will not affect its ability to work, however alcohol may generally impede an erection and should be avoided in excess. No more than one tablet should be taken a day.
If you plan to buy Viagra, which is available from pharmacists online in the UK, then it is important not to exceed the stated dose, as this will not improve is efficacy but may increase the side effects. When taken at the recommend dose clinical trials have proven the side effects, which may include headache and facial flushing, to be mild to moderate and brief in length. However it should not be taken in conjunction with other medicines containing nitrates, and patients should inform their doctor if they plan to use it in conjunction with other medicines.
