Pregnancy and breast-feeding
Prochlorperazine should not be used in pregnancy, unless your doctor considers it absolutely
necessary. As prochlorperazine is passed into breast milk, breastfeeding should be suspended during
treatment. The following symptoms may occur in newborn babies, of mothers that have used
Prochlorperazine in the last trimester (last three months of their pregnancy): shaking, muscle
stiffness and/or weakness, sleepiness, agitation, breathing problems, and difficulty in feeding. If
your baby develops any of these symptoms you may need to contact your doctor.

Driving and using machines

This medicine may cause some people to become drowsy or less alert than usual. If you are
affected, do not drive or operate dangerous machinery.

Sugar intolerance
If a doctor has told you that you have an intolerance to some sugars, check with your doctor before
taking these tablets, as they contain
a type of sugar called lactose.

3. How to take Prochlorperazine tablets
You will be prescribed the lowest dose needed to control your symptoms. You should check with
your doctor or pharmacist if you are unsure. Do not stop taking your medicine or change the
dose unless your doctor tells you to.
The tablets should be swallowed with a glass of water.

Do not crush the tablets or handle them more than you need to because you may develop a
skin reaction.
Dose for nausea and vomiting
Adults: Prevention of nausea and vomiting 510mg two or three times a day. Treatment of
nausea and vomiting:
20mg followed if
necessary by 10mg two hours later.

and vomiting:
The dose will depend on the child's bodyweight
and will be calculated on the basis of 250
micrograms per kilogram bodyweight two or three
times a day. Prochlorperazine is not recommended
for children weighing less than 10 kilograms or
children less than two years of age.

Dose for anxiety
Adults: Initially 15-20mg daily in divided
doses. This may be increased if necessary to a
maximum of 40 mg daily in divided dose.

Dose for vertigo and Meniere's syndrome:
Adults: 5mg three times daily, increased if needed
to 30mg daily. Dosage may be reduced gradually to
5-10mg daily.

Elderly patients with mental disorders should
be started on a lower dose of Prochlorperazine.
It should be used with caution during very hot
or very cold weather to reduce the risk of an
extreme rise or fall in body temperature.

Dose for schizophrenia and other psychotic
(mental) disorders:
Adults: The usual dose is 12.5mg twice daily
for 7 days. The dose is then increased by
12.5mg at 4-7 day intervals until it has a
satisfactory effect. After you have been on an
effective dose for some weeks, your doctor
may advise you to try to reduce the dosage.


If you take more than you should
If you accidentally take more tablets or somebody else takes any tablets, contact a doctor or go to
your nearest hospital casualty department at once. Take any remaining tablets with you and the
container or packaging, so they can be identified.

If you forget to take a tablet

If you miss a dose, skip the missed dose and go back to your regular schedule. Do not take a
double dose to make up for a forgotten dose.
