1. What Serdolect is and what it is used for


Serdolect contains the active substance sertindole and belongs to a group of medicines known as antipsychotics. It acts on nerve pathways in specific brain areas and helps there to correct chemical imbalances that cause your symptoms.

Serdolect is used to treat schizophrenia in cases where another medicine was not effective.

2. What you need to know before you take Serdolect


Do not take Serdolect

if you are/have:

•    allergic to sertindole or any of the other ingredients of this medicine (listed in section 6).

•    untreated low potassium or magnesium in the blood

•    a significant heart and blood circulation disease

•    a severe heart disease such as

-    heart failure with tissue swelling caused by excess fluid

-    enlargement of the heart

-    irregular or slow heartbeat

•    born with or have had an episode of prolonged heart ventricle activity, measured in an ECG, or someone in your family has this abnormal heart rhythm

•    severely reduced liver function

•    taking medicines that prolong the time of the heart ventricle activity or affect the liver function. See the first two bullet points under "Other medicines and Serdolect” in section 2.

Warnings and precautions

Talk to your doctor before taking Serdolect if you are/have:

•    vomiting or diarrhoea during treatment with Serdolect

•    reduced liver function

•    Parkinson's disease

•    diabetes or risk factors for developing diabetes

•    risk factors for stroke, such as high blood pressure, previous stroke or heart attack, diabetes, high cholesterol, dementia, smoking

•    over 65 years of age

•    a history of blood clots in a vein, or a family history of such blood clots, as medicines for treatment of schizophrenia have been associated with formation of blood clots

•    had fits

•    unusual mouth and tongue movements, which may be early signs of the nervous system disorder called tardive dyskinesia

•    high fever, unusual muscle stiffness and changes in consciousness, especially if occurring with sweating and fast heartbeat. These may be signs of a rare but serious condition called neuroleptic malignant syndrome

At the beginning of treatment with Serdolect, you may feel dizzy when you get out of bed or stand up. Your doctor will reduce this risk by starting with a low dose, to increase gradually over several weeks. This feeling usually goes away when you have taken Serdolect for a while.

Monitoring before and during treatment

Your doctor will conduct examinations before and during treatment with Serdolect, such as:

•    an ECG of your heart ventricle activity to check for QT interval prolongation This test is repeated after 3 weeks of treatment or when you reach a daily dose of 16 mg sertindole. During maintenance treatment, it should be performed every 3 months. In addition, an ECG will be performed before and after dose increase. This also applies after changes to other medicines that may affect the sertindole blood level.

•    a test of potassium and magnesium blood levels

If the level of potassium or magnesium is reduced, your doctor will initiate treatment to correct this. Do not take Serdolect if you have an untreated low potassium or magnesium blood level.

Contact your doctor if you experience vomiting, diarrhoea, electrolyte disturbances or take medicines to increase water output. Your doctor may measure the amount of potassium in your blood.

•    blood pressure monitoring

Children under 18 years

Serdolect should not be used in this age group as no data are available.
