What is Desogestrel? |
|
Desogestrel
is a molecule used in hormonal contraceptives.
Third generation pills have been
shown to resolve or to reduce acne and hirsutism.
They are suitable for use in patients with diabetes
or lipid disorders because they have minimal impact
on blood glucose levels and the lipid profile. Their
dosage is lower than other oral contraceptives. |

|
|
How
does Desogestrel work? |
|
Desogestrel contains a hormone
which is similar to the hormone progesterone that is
produced by the body. It is used to prevent women
from becoming pregnant. It works by preventing the
release of eggs from the ovary and by increasing the
thickness of vaginal fluid which can stop a sperm
from reaching an egg. |

How should I use Desogestrel? |
|
Hormonal contraceptives will only prevent a pregnancy if
they are taken regularly. It is important you take
this medicine at the same time each day. When you
first start to take Desogestrel you may need to take
extra contraceptive precautions until it starts to
work. You may also need to take extra contraceptive
precautions in certain situations. These situations
include missing a dose by more than 12 hours or
vomiting within three to four hours of taking
Desogestrel. Ask your prescriber, family planning
nurse or read the patient information leaflet that
comes with your medicine for more information about
