What are nausea,
vomiting
and retching?
Nausea is the queasy feeling in the stomach which may lead to
the urge to vomit. Vomiting is the actual act of getting
rid of the contents of the stomach through the mouth, or "throwing
up." Retching, also called "dry
heaves" is an attempt to vomit that does not remove
anything from the stomach.

Why do
I get sick?
Nausea is controlled by a part of the nervous
system that controls certain body functions that we often take
for granted, like breathing. A special area of the brain called
the vomiting
center manages vomiting.
When a person receives chemotherapy, radiation therapy or following
some surgical procedures, the body releases a chemical that causes
the vomiting center to cause nausea and vomiting.

Are
there medicines to help prevent nausea and vomiting?
Yes. CINV/RINV and PONV can be controlled by treatment with
antiemetics.
Talk to your doctor, nurse or pharmacist about which of these treatments
is best for you. Things your healthcare professional might consider
when selecting a medicine include your cancer treatment, previous
history of nausea and vomiting, potential interactions with other
medicines you are taking, and potential benefits, such as full 24-hour
coverage and easy dosing.

When
will I be given the medicines?

Why should I be worried about nausea and vomiting?
If not controlled properly, nausea and vomiting can have serious
effects on your health, which may even lead to hospitalization.
Following cancer treatment or surgery, nausea and vomiting can have
a big impact on your health and well being. Being more comfortable
after cancer treatment means you will be more likely to complete
your entire treatment course — the most important thing you can
do to fight your cancer.

How
soon will I get sick?
Typically people begin to feel sick shortly after their cancer treatment
begins, although, the type of treatment often dictates when a person
will start to feel the effects. Some will feel sick immediately
upon receiving treatment, while others may not feel ill until several
hours or days later.
Patients who have undergone surgery often feel sick when they wake
up from the anesthesia.
Remember, not everyone will get sick, but if you do experience
nausea and vomiting, there are medicines available to help you.
Talk to your doctor, nurse of pharmacist.

What
if I’m taking medicine to prevent nausea and vomiting and I
still feel sick?

taking an antiemetic
and you still feel sick, contact your doctor, nurse of pharmacist
and ask if other medicines might work better.

happens if my nausea wakes me up in the middle of the night?

Will
my current medicines affect my nausea and vomiting medicines?

an adverse reaction, which may have serious consequences. Make sure
you tell your doctor and pharmacist about all of the medicines you
are taking, including prescription medications, vitamin supplements,
herbal supplements, aspirin, etc. He or she will be able to give
you medicine for your nausea and vomiting which is less likely to
interact with your other medicines.
