6. Contents of the pack and other information
Olanzapine contains the active substance olanzapine and
belongs to a group of medicines called antipsychotics.
Olanzapine is used to treat schizophrenia, a disease with
symptoms such as hearing, seeing or sensing things which
are not there, mistaken beliefs, unusual suspiciousness,
and becoming withdrawn. People with this disease may
also feel depressed, anxious or tense.
Olanzapine is used to treat moderate to severe manic
episodes, a condition with symptoms such as feeling
"high", having excessive amounts of energy, needing
much less sleep than usual, talking very quickly with
racing ideas and sometimes severe irritability. It is also a
mood stabiliser that prevents further occurrences of the
disabling high and low (depressed) extremes of mood
associated with this condition.
Do not take Olanzapine:
• If you are allergic (hypersensitive) to olanzapine or
any of the other ingredients of this medicine (listed in
section 6). An allergic reaction may be recognised as a
rash, itching, a swollen face, swollen lips or shortness of
breath. If this has happened to you, tell your doctor.
• If you have been previously diagnosed with eye
problems such as certain kinds of glaucoma (increased
pressure in the eye).
Warnings and precautions
Talk to your doctor before taking Olanzapine.
• Medicines of this type may cause unusual movements
mainly of the face or tongue. If this happens after you
have been given Olanzapine tell your doctor.
• Rarely, medicines of this type cause a combination of
fever, faster breathing, sweating, muscle stiffness and
drowsiness or sleepiness. If this happens, contact your
doctor at once.
• If you or someone else in your family has a history of
blood clots, as medicines like these have been associated
with formation of blood clots.
• Weight gain has been seen in patients taking Olanzapine.
You and your doctor should check your weight regularly.
• High blood sugar and high levels of fat (triglycerides
and cholesterol) have been seen in patients taking
Olanzapine. Your doctor should do blood tests to check
blood sugar and certain fat levels before you start taking
Olanzapine and regularly during treatment.
• The use of Olanzapine in elderly patients with dementia
is not recommended as it may have serious side effects.
If you suffer from any of the following illnesses tell your
doctor as soon as possible:
• Diabetes
• Heart disease
• If you have been told that you have salt imbalances
in the blood (especially low levels of potassium or
• If you were born with prolonged QT interval (seen on
ECG, an electrical recording of the heart)
• Liver or kidney disease
• Parkinson’s disease
• Epilepsy
• Prostate problems
• A blocked intestine (Paralytic ileus)
• Blood disorders with low blood white blood cell counts
(which can be caused by some medicines, radiation
therapy, chemotherapy or bone marrow disease)
• If you have been told that you have increased levels
of some white blood cells or a disease of the bone
marrow in which excessive blood cells are made called
myeloproliferative disease
• Stroke or “mini” stroke (temporary symptoms of stroke)
If you suffer from dementia, you or your carer/relative
should tell your doctor if you have ever had a stroke or
“mini” stroke.

pressure may be monitored by your doctor.
Children and adolescents

Other medicines and Olanzapine
Tell your doctor if you are taking, have recently taken or
might take any other medicines. Especially tell your doctor
if you are taking medicines for Parkinson’s disease.
Only take other medicines while you are on Olanzapine if
your doctor tells you that you can. You might feel drowsy
if Olanzapine is taken in combination with antidepressants
or medicines taken for anxiety or to help you sleep
You should tell your doctor if you are taking
carbamazepine (used as an anti-epileptic or mood
stabiliser), fluvoxamine (an antidepressant), or
ciprofloxacin (an antibiotic), as it may be necessary to
change your Olanzapine dose.

quinidine, disopyramide), antibiotics (that belong to the
group of macrolides), tricyclic antidepressants.
If you are taking activated charcoal (a chemical substance
used to bind other drugs), this should be taken at least
2 hours before or after olanzapine intake because it can
interfere with the absorption of olanzapine.
Olanzapine with alcohol
Do not drink any alcohol if you have been given Olanzapine
as taking it with alcohol may make you feel drowsy.
