Side effect What is it? What should I do if it happens to me?
COMMON
AKATHISIA You feel restless, unable to feel comfortable
unless you are moving.
Tell your doctor about this. It may be possible to change your drug
or dose, or give you something to reduce these feelings.
MOVEMENT
DISORDERS
Feeling shaky or having a tremor. Your neck
may twist back. Your eyes and tongue may
move on their own.
It is not usually dangerous. If it is bad or worries you, tell your
doctor. He or she can give you something for it.
RAISED
PROLACTIN
Prolactin is a natural chemical we all have.
High levels can affect periods in women or
cause impotence in men. It may also cause
breast tenderness and milk secretion, in men
as well as women.
This sometimes wears off in a few weeks, but discuss this with
your doctor anyway. It may be that a change in dose or different
drug will help.
WEIGHT GAIN Eating more and putting on weight. Avoid fatty foods like chocolate, crisps and fizzy drinks. A diet full
of vegetables and fibre will usually help, as will physical activities
such as walking. If it becomes a problem or you are worried, ask
to see a dietician.
LESS COMMON
DROWSINESS Feeling sleepy or sluggish. Don’t drive or use machinery. As your treatment continues you
should feel less drowsy.
UNCOMMON
Dry mouth. Not much saliva or spit. Sugar-free boiled sweets, chewing gum or eating citrus fruits
usually helps. If not, your doctor can give you a mouth spray. A
change in medicine or dose may be possible.
Blurred vision Things look fuzzy and you can’t focus properly. See your doctor if
you are worried. You won’t need glasses.
Feeling "bunged up" inside. You can't pass a
motion or stool.
Eat more fibre e.g. bran, fruit and vegetables. Do more walking.
Make sure you drink plenty of fluid. A mild laxative from a
pharmacy might help.

for sex. Men can become impotent.
Discuss this with your doctor when you next meet.
SWELLING

lumpy.
Report it to your nurse. Warm baths and regular exercise like
walking can help.
RARE

when you stand up.
Try not to stand up too quickly. If you feel dizzy, don’t drive. This
dizziness is not dangerous
VERY RARE
NMS Neuroleptic Malignant Syndrome includes a
high body temperature, muscle stiffness and
being unable to move.
It usually occurs within a few weeks of a dose change. Contact
your doctor immediately. Keep cool, with fans or cool water.
What about alcohol?
It is officially recommended that people taking flupentixol should not drink alcohol. This is because both flupentixol and alcohol can
cause drowsiness. If the two are taken at the same time, severe drowsiness can result. This can lead to falls or accidents. As well as
this, drinking alcohol often makes psychosis worse. Excessive drinking is especially likely to do this. Once people are used to taking
medication, they can sometimes drink alcohol in small amounts without any harm. Avoid alcohol altogether for the first one or two
months. After this, if you want a drink, try a glass of your normal drink and see how you feel. If this doesn’t make you feel drowsy, then
it is probably OK to drink small amounts. It pays to be very cautious because alcohol affects people in different ways, especially when
they are taking medication.
Don't stop taking your medication because you fancy a drink. Discuss any concerns you may have with your doctor, pharmacist or
nurse. If you do drink alcohol, drink only small amounts. Never drink any alcohol and drive.
