information on a Viagra topic, you can seek advice from your doctor or the
USAmedix doctors will be happy to help. The Viagra guide below, which has
been compiled by USAmedix, is only an outline of the main information that
you need to know before taking Viagra and it must be not be used as a comprehensive
guide. If there is any aspect of taking Viagra that you are concerned about
please contact your doctor before ordering.
Do you need to take Viagra?
Viagra is a drug that has been developed by the pharmaceutical company Pfizer,
to enable the treatment of men with impotence or erectile dysfunction. This
medication is available by prescription only and should only be taken if and
when you desire to have sexual intercourse. Viagra will only be active when
the man is sexually aroused which may be either physical or visual, but there
needs to be sexual stimulation for the Viagra to take effect. At USAmedix
we only prescribe Viagra for men, as Viagra is not for women and we will not
issue prescriptions to females. We also advise that Viagra is not taken by
women under any circumstances. Studies of Viagra usage in women have not been
carried out by Pfizer and therefore it is not recommended. But USAmedix will
keep you updated with the developments into new products that are designed
for women, currently known as Intrinsa, which is a type of testosterone patch.
Very Short History of Viagra
Viagra did not start of as being a drug to treat impotence but it was developed
as a medication for high blood pressure and hypertension. But when the scientists
at Pfizer started to do the clinical trials on Viagra they realised that they
had developed a drug that potentially could change sexually history across
the world forever. During the trials of Viagra it was noted that one of the
side effects was that impotent men were getting erections when they took Viagra.
How does Viagra work exactly?
Viagra helps men with impotence or erectile dysfunction to get an erection
when they become sexually stimulated. Viagra works in the body by causing
the smooth muscles in the penis to relax which allows there to be an increased
blood flow into the penis. The active ingredient of Viagra is called Sildenafil
which is a PDE5 inhibitor. This is what causes the increased blood flow into
the penis. Viagra is helped by the body’s natural processes when stimulated
which makes the penile arteries relax. When the arteries in the penis enlarge
and are filled with blood the veins which would normally carry the blood away
from the penis are compressed which restricts the blood flow out. This then
causes an erection and the effects of Viagra will keep the erection and normal
sexual intercourse can be carried out. It was often thought that impotence
was a psychological disorder in men but the invention of Viagra made it clear
that although some impotence problems can be caused by psychological problems,
most cases are due to the nerves and blood vessels in the penis. If these
nerves and blood vessels in the penis do not function correctly then it can
cause impotence, which is now successfully treated with Viagra.
How long does Viagra work for?
In clinical studies it has been shown that Viagra works successfully on
around 80% of patients and will become active within an hour. Viagra is one
of the quickest impotence medications on the market to start to work. Depending
on the patient, the average time that Viagra is active for is 4 hours. From
our research at USAmedix we have seen that sometimes patients feel that there
is too much planning involved around sexual activity when taking Viagra. There
are other impotence medications available at USAmedix, such as Cialis which
does show that it can last up to 36 hours. Our feedback at USAmedix from patients
has shown that in some cases it can take Cialis longer to take effect than
Viagra though.
What is the Viagra dosage?
There are 3 different dosages of Viagra available from USAmedix of 25mg,
50mg and 100mg. The manufacturers of Viagra, Pfizer, recommend that the starting
dosage for Viagra is 50mg, and we here at USAmedix agree with this. The USAmedix
doctors agree that you should always start at this dosage and adjust accordingly
to find the level that suits your situation. When taking Viagra, just as any
other prescription drug, you must follow the guidelines given to you by your
doctor. Viagra should be taken about an hour before any sexual activity, as
a single tablet that is at the correct dosage. Viagra can be taken with or
without meals. USAmedix recommend that the information that is supplied with
the Viagra is read carefully before the tablets are taken.
