1. WHAT Risperidone IS AND WHAT IT IS USED FOR
Risperidone belongs to a group of medicines called antipsychotics.
Risperidone is used:
• to treat schizophrenia (a severe mental illness characterised by symptoms such as delusional ideas, perceiving things that
are not there (hallucinations) and a gradual change of personality).
• to keep schizophrenia under control after the previous symptoms have declined, to prevent the illness from returning in
its full intensity.
2. BEFORE YOU TAKE Risperidone
Do not take Risperidone
• if you are allergic (hypersensitive) to risperidone or any of the other ingredients of Risperidone tablets.
An allergic reaction may manifest as rash, pruritus, oedema of the face and lips or dyspnoea.
• if you have an abnormally high concentration of the hormone prolactin in the blood.
Take special care with Risperidone
Tell your doctor if you suffer from the following conditions:
• heart or vascular disease (e.g. low blood pressure)
• Parkinson’s disease
• dementia or you have previously had a stroke or a disorder of blood supply to the brain (because treatment with
Risperidone can cause impaired cerebral blood ﬂow possibly leading to stroke, particularly in elderly patients)
• Lewy body dementia (a special form of dementia)
• liver or kidney disease. Your treatment may need to be adjusted (see section 3)
• diabetes mellitus
• breast cancer (and other speciﬁc tumors which can be correlated to the hormone prolactin, e.g. hypophysal
Tell your doctor immediately if you experience:
• involuntary rhythmic movements of the tongue, mouth and facial muscles
• fever, severe muscular stiffness, sweating or a lowered level of consciousness
• signs and symptoms such as sudden weakness, numbness in the face, arms or legs, particularly on one side, or
If you are of an advanced age:
In elderly people, dizziness, excessively low blood pressure and injury as a result of a tendency to fall occurs more often than
in younger people.
If signs such as agitation, restlessness and aggressiveness are exacerbated: Antipsychotics can sometimes cause this, in
which case a reduction of the dose or discontinuation of treatment may be necessary.
Please also tell your doctor if you have a factor increasing susceptibility to cardiovascular diseases, such as high blood
pressure, diabetes, cardiac dysfunction called atrial ﬁbrillation or if you smoke.Your doctor will decide whether you can take
Risperidone tablets and if the dosage should be adjusted.
Be cautious taking Risperidone if you are exposed to temperature extremes, because abnormally changes in body
temperature can occur.
Avoid dehydration. Refrain from excessive eating to avoid weight gain during Risperidone treatment.
Using other medicines
Please tell your doctor or pharmacist, if you are taking or have recently taken any other medicines, including medicines or
herbal and natural products obtained without a prescription.
Some medicines can cause problems if you take them with Risperidone. These include:
• medicines acting upon the central nervous system (e.g. levodopa, used to treat Parkinson’s disease): risperidone may
weaken the effect of levodopa
• opiates (used to treat severe pain), antihistamines (used to treat allergies) and benzodiazepines (tranquilizing
medicines): their effect is increased by risperidone
• other antipsychotic medicines (used to treat psychiatric disorders), lithium and antidepressants (used to treat
depressions), medicines to treat Parkinson’s disease and other medicinal products with a speciﬁc effect on the central
nervous system: the risk that movement disturbances (tardive dyskinesia) occur as side effect is increased
• neuroleptics (used to treat psychiatric disorders), antiarrhythmics class IA or III (used to treat heart disease), antibiotics
(used to treat bacterial infections), medicines to treat malaria, antihistamines (used to treat allergies) and
antidepressants (used to treat depressions): cardiac disorders may occur
• certain diuretics (like chlorothiazide and furosemide),used to treat swellings (oedema) caused by water retention in the
body: the body may lose too much water and minerals (sodium, chloride) and especially with furosemide when used in
elderly patients with dementia cardiac disorders may occur. Thus concomitant use of furosemide with Risperidone is
• certain blood pressure lowering medicines, e.g. phenoxybenzamine, labetalol, methyldopa, reserpine: risperidone can
increase their effect
• guanethidine, used to treat high blood pressure: risperidone blocks the effect
• carbamazepine, phenytoin and phenobarbital (used to treat epilepsy), barbiturates (used for sedation), rifampicin (used
to treat tuberculosis), the herbal remedy St. John’s wort (Hypericum perforatum, used to treat depressive mood changes):
they may weaken the effect of risperidone
• antacida (used to treat stomach problems, e.g. heartburn): they may reduce the amount of Risperidone which is taken up
by the body
• medicines which may increase the concentration of Risperidone in the blood so that your doctor might need to adjust
the dose of Risperidone:
• phenothiazines, used to treat psychiatric disorders
• ﬂuoxetine, paroxetine and tricyclic antidepressants, used to treat depressive conditions
• quinidine, used to treat heart disease
• terbinaﬁne, used to treat certain fungal infections
• beta-blockers, used to treat high blood pressure

damage to the tablet. Remove a tablet from the package as follows:

perforations around it.
2. Pull up the edge of the foil and peel foil off completely.
3. Tip the tablet out onto your hand.
4. Put the tablet on the tongue as soon as it is removed from the packaging.

The mouth should be empty before placing the tablet on the tongue.

the dosage until a dose suitable for you is achieved.

Treatment is started gradually, e.g. 2 mg on the ﬁrst day and 4 mg on the second day.
The daily dose can be taken in one dose or divided into two subdoses, one taken in the morning and another one in the
evening. However, your doctor may recommend to increase the dose more slowly.
Thereafter, the dosage may remain the same or it can be adjusted, if necessary. The usual dose is 4-6 mg daily, but a dose less
than 4 mg may be adequate for some patients.
Children and adolescents
Use of the product is not recommended for children and adolescents below the age of 15 years due to lacking experience.
The recommended starting dose is 0.5 mg twice daily. This dose can be adjusted, in steps of 0.5 mg twice daily, to a dose
of 1 to 2 mg twice daily. Caution should be exercised because little experience has been acquired in the treatment of
Patients with cardiovascular disease
The doctor will prescribe the dosage which is appropriate for you. Dependent on the kind of disease and its severity the
dosage can be lower as described above.
Patients with impaired liver or kidney function
The doctor will prescribe the dosage which is appropriate for you. Dependent on the kind of impairment and its severity the
dosage can be as described above or only half of that.
Follow carefully the instructions from your doctor and do not change the dosage or discontinue the medicine without
discussing with your doctor ﬁrst.
Tell your doctor or pharmacist if you feel that the efﬁcacy of Risperidone tablets is too strong or too weak.
If you take more Risperidone than you should
If you have taken too much of Risperidone contact your doctor or a hospital straight away. Signs of an overdose needing
medical care straight away are: fatigue, accelerated heart beat (tachycardia), low blood pressure (hypotension) and
extrapyramidal symptoms like tremor, muscular stiffness, increased salivation, slowness of movements, restless legs and
sudden muscular contractions.
If you forget to take Risperidone
Skip the forgotten dose and continue taking the medicine normally as instructed by the doctor.
If you stop taking Risperidone
