What side effects can Prochlorperazine cause?
Along with its needed effects the medicine may cause some
unwanted effects:
In elderly people with dementia, a small increase in the
number of deaths has been reported for patients taking

antipsychotics compared with those not receiving
Nasal stuffiness, dry mouth, insomnia, agitation, dizziness
when standing from a lying or sitting position, changes in
heart rate, slowing of breathing in certain individuals.
Abnormal movement, tremors and muscle stiffness, and,
usually in young patients, an inability to control certain
muscles of the body such as tongue, mouth, arms and legs.
You may experience extreme restlessness or agitation.
These symptoms usually disappear after treatment with
prochlorperazine is discontinued.
Blood clots in the veins especially in the legs (symptoms
include swelling, pain and redness in the leg), which may
travel through blood vessels to the lungs causing chest pain
and difficulty breathing.
A combination of high-temperature, pale complexion, muscle
stiffness and changes in levels of alertness are symptoms of
a serious condition called ‘neuroleptic malignant syndrome’.
If these symptoms develop, you should inform your doctor
After weeks or months of treatment it is possible that
uncontrolled shaking of the hands or limbs and muscle
stiffness may occur.
Disorders of the blood may occur during prolonged treatment
or with high doses. If you develop a fever or experience an
unusually bad sore throat or bruising, this could be a
symptom of a blood disorder and you should tell your doctor
Jaundice (yellowing of the skin and whites of the eyes) may
occur, sometimes preceded a sudden onset of fever, 1-3
weeks after the start of treatment. If you develop jaundice,
stop the treatment and inform your doctor immediately.
In sunny weather the skin may become sensitive to sunlight,
therefore direct exposure to sunlight should be avoided.
Although never reported with prochlorperazine, it is possible
that visual changes and a greyish discoloration of exposed
skin may develop, but only after continuous long term use.
Swollen breasts can occasionally occur in men, but only after
long term use. Impotence can also sometimes occur.
Unusual breast milk production and absence of menstrual
periods can sometimes occur in women.
