Viagra The Popular ED Pill
What is Viagra?
Viagra is
a prescription medicine used in the treatment of erectile dysfunction and
impotence in men. Viagra is also used to treat erectile dysfunction and is available without the need of a prescription. They
both work by increasing blood flow to the penis in order to help a man get and
sustain an erection when he is sexually aroused or stimulated.
The
active ingredient in Viagra is sildenafil and the dose ranges from
25mg to 100mg per tablet.
How long does Viagra take to
work?
The
effects of Viagra will vary from person to person. As a general rule,
Viagra is thought to start working in most people from around 30 minutes after
taking the drug.
It is
important to understand that taking Viagra tablets alone will not cause an
erection. Viagra must be taken in combination with some form of sexual
stimulation (visual, tactile or otherwise) in order for an erection to occur.
How long does Viagra last?
The
length of time Viagra lasts for will also vary from person to person, but it
has been known to work for up to 5 hours at
a time, when used alongside sexual stimulation. Most men will find, however,
that the effects of the pill will start to wear off 2-3
hours after first taking it.
There
are certain factors that will contribute to how long Viagra will last for in
your individual situation, and you should always discuss your full medical
history and details of any medicines you are currently taking before starting a
course of treatment with Viagra.
Which factors will affect how long Viagra lasts for?
The
effectivity of Viagra, or how long Viagra will last for, depends on a number of
things. These can include:
·
Age. Men over 65
years of age will find that the tablet stays in their body for longer because
the body’s metabolic system tends to slow down with age. Essentially, this
means that Viagra’s effects can last longer the older you are.
·
Diet. Having a
large meal with a high fat content just before you take your Viagra pill can
delay it from working as your body will be working hard to digesting the food.
By taking it on an empty stomach, the effects will work more quickly.
·
Alcohol. Drinking
alcohol decreases the blood flow to the penis making it harder to get and keep
an erection. A glass of wine or a single beer is usually fine, but more than 2
units of alcohol will increase the risk of negative side effects and will make
it much more difficult to maintain an erection.
·
Dosage. Viagra comes in
tablets ranging in dose from 25mg to 100mg. As a rule of thumb: the higher the
dose, the more effective and long-lasting the effects will be, but your
prescribing doctor will decide which dosage is appropriate in your situation.
·
Health. If you have
liver or kidney problems, Viagra’s effects could last for longer. This is
because the tablet will take longer to be broken down by your body, so you must
always tell the doctor if you suffer from any of these.
·
Drug interactions. Certain
medicines can alter how long the effects of Viagra will last. This includes
medicines such as the antibiotic rifampicin (used to treat tuberculosis).
Always discuss your full medical history and any medicines you are currently
taking with your prescribing doctor so that they can ensure it is safe for you
to take Viagra.
