Tetmodis is a medicine belonging to the group treating disorders of the nervous system.
Tetmodis is used for the treatment of diseases causing jerky, irregular, uncontrollable movements
(hyperkinetic motor disorders with Huntington’s chorea).
Do not take Tetmodis
- if you are allergic (hypersensitive) to tetrabenazine or any of the other ingredients of Tetmodis 25 mg
- if you use reserpine (medicine to control high blood pressure and treat psychotic states).
- if you use MAO inhibitors (medicine to treat depression)
- if you suffer from Parkinson-like symptoms
- if you have a depression
- if you are breast-feeding
- if you suffer from pheochromocytoma (tumour of the adrenal gland)
- If you suffer from pro-lactin-dependent tumours, e.g. pituitary or breast cancer
Take special care with Tetmodis
- if you are suffering from mild to severe hepatic impairment
- if you have a heart condition known as long QT syndrome or if you have or have had problems with
your heart rhythm.
- if you start to have mental changes such as confusion or hallucinations, or develop stiffness in your
muscles and a temperature, you may be developing a condition called Neuroleptic Malignant
Syndrome. If you have these symptoms please contact your doctor straight away.
Taking other medicines
Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines,
including medicines obtained without a prescription.
Take special care if you use Tetmodis together with Levodopa (a medicine used to treat Parkinson’s
disease). Do not use Tetmodis together with reserpine. Treatment with MAO inhibitors should be stopped
14 days before the treatment with tetrabenazine starts.

It is not recommended to use this medicine with certain types of antidepressants, alcohol,opioids, beta
blockers, antihypertensive drugs (medicine to treat high blood pressure), hypnotics and neuroleptics
(medicine to treat psychotic disorders).
Inhibitors of CYP2D6 (e.g. fluoxetine, paroxetine, terbinafine, moclobemide and quinidine) may result in
increased plasma concentrations of the active metabolite dihydrotetrabenazine, why they should only be
combined with caution. A reduction of the tetrabenazine dose may be necessary.
Take special care if you use Tetmodis together with drugs known to prolong the QTc interval in the ECG,
including some drug used to treat mental health conditions (neuroleptics), certain antibiotics (e.g.
gatifloxacin, moxifloxacin) and some drugs used to treat problems with heart rhythm conditions (e.g.
quinidine, procainamide, amiodarone, sotalol).
Pregnancy and breast-feeding
Ask your doctor or pharmacist for advice before taking any medicine. Your doctor will decide after
taking all risks and benefits into account, if you may use Tetmodis during pregnancy. Tetmodis must not
be taken by breast feeding mothers.
Driving and using machines
Tetmodis may cause drowsiness and therefore may modify your performance at driving and using
machines to a varying degree, depending on the dose and individual susceptibility.
Important information about some of the ingredients of Tetmodis
These tablets contain lactose. If you have been told by your doctor that you have an intolerance to some
sugars, contact your doctor before taking this medicinal product.
Always take Tetmodis exactly as your doctor has told you. You should check with your doctor or
pharmacist if you are not sure.
Huntington’s chorea
The recommended starting dose is half a tablet (12.5 mg) one to three times a day. This can be increased
every three or four days by half a tablet until the optimal effect is observed or up to the occurrence of
intolerance effects (sedation, Parkinsonism, depression).
The maximum daily dose is 8 tablets (200 mg) a day.
If you have taken the maximum dose for a period of seven days and your condition has not improved, it is
unlikely that the medicinal product will be of benefit to you.
The elderly
The standard dosage has been administered to elderly patients without apparent side effects. However,
Parkinson-like side effects are common.
The treatment is not recommended in children.
Patients with hepatic disorder
Patients with mild to moderate hepatic disorders should start with half a tablet a day. For patients with
severe hepatic disorders, additional caution is necessary.
Patient with renal disorder
Tetmodis is not recommended for use in this patient group.
Swallow the tablet(s) with water or another non-alcoholic drink.


If you take more Tetmodis than you should
If you take more Tetmodis than you should, you may develop drowsiness, sweating, low blood pressure,
and extremely low body temperature (hypothermia). Your doctor will treat the signs.
If you forget to take Tetmodis
If you forget to take one dose, you should never make up for the missing dose by doubling it at the next
time. Instead you should simply continue with the next dose when it is due.
If you stop taking Tetmodis
Do not stop taking Tetmodis unless your doctor tells you to. A neuroleptic malignant syndrome has been
described after abrupt withdrawal of tetrabenazine.
If you have any further question on the use of this product, ask your doctor or pharmacist.
