What is Propecia?
Propecia is an oral medication designed to treat male pattern
hair loss on the vertex (top) and anterior mid scalp area.
Propecia has not been proven to treat hair loss at the hairline.
|
 |
Has Propecia been tested?
Propecia was studied in men ages 18 to 41 that showed mild
to moderate hair loss. There was not enough evidence to support
Propecia as a treatment for hair loss at the temporal areas
of the head. Propecia is a treatment that should only be used
by men. Because the active ingredient in Propecia has the
power to cause abnormalities in a developing child, pregnant
women should never use or touch a broken tablet. Propecia
also has the ability to affect the PSA test, a screen for
prostate cancer. If you are going to have the PSA test, you
should remind your doctor you are taking Propecia.

Does Propecia really work?
Based on two studies over 24 months, 83% of the men in the
trial suffering hair loss maintained their hair count. Additionally,
66% of these men had visible regrowth of hair as reported
by a 3rd party dermatologist. Most men in the study reported
an increase in hair growth and a decrease in hair loss. You
may need to take Propecia daily for 3 months or more before
you are able to see visible results. Propecia is not guaranteed
to regrow all your hair and if you stop using Propecia, you
will gradually lose all the hair it has regrown. If after
12 months you do not see sufficient hair growth evidence,
further treatment is likely to be of little benefit. Taken
once a day in tablet form Propecia is proven to grow real
strands of hair back.

 |
What are the most common side
effects of Propecia?
The most common side effects in men where decreased sexual
response and function. These side effects appeared in less
than 2% of men and went away when the men stopped taking Propecia.
|
 |
How does Propecia work?
It is believed that DHT, a hormone in the male body, is a
prime candidate for hair loss. Propecia blocks the formation
of DHT in the scalp region. By blocking DHT in the scalp normal
hair loss and regrowth patterns will continue, avoiding thinning
and eventual permanent hair loss.
|
 |
Who should not take Propecia?
Propecia is only for men, designed to stop DHT, a hormone
in men that deteriorates normal hair growth patterns. Women
who are pregnant should not handle a broken tablet. All tablets
are coated so that normal handling will not place anyone in
contact with the active ingredient.
|
 |
How should Propecia be taken?
Consult your doctor before beginning to take Propecia. When
taking Propecia please follow your doctor’s dosage recommendations.
Exceeding your doctors prescribed dosage will not increase
the effectiveness of Propecia. You will need to continue to
take Propecia for as long as you wish to have the benefit
of the medication. Once you stop taking Propecia, you will
gradually lose all the hair it has regrown. Propecia is supplied
in 1-milligram tablets, and may be taken with or without food.
Propecia is a prescription medication and can only be purchased
after a visit with your doctor or other healthcare professional.

 |
Can I take Propecia if I am
taking any other medications?
You should always consult with your doctor before taking
any new medication. But Propecia has been tested in combination
with a multitude of other drugs and no interactions were discovered.
