When starting treatment with Serdolect, you may feel dizzy when getting up from bed or standing up. Your doctor may reduce this risk by starting with a low dose, gradually increasing it over several weeks. This feeling usually disappears when you have taken Serdolect for a while.

Monitoring before and during treatment

Before and during your treatment with Serdolect, your doctor may perform certain tests, such as:

•an electrocardiogram of your ventricular cardiac activity to check if there is prolongation of the QT interval

This test is repeated after 3 weeks of treatment or when you reach a daily dose of 16 mg of sertindol. During maintenance treatment, it will be done every 3 months. In addition, an ECG will be done before and after increasing the dose. This will also be done if you change the dose of another medication you take that may affect the level of sertindol in the blood.

•potassium and magnesium level test in the blood

If potassium or magnesium levels decrease, your doctor will start treatment to correct it. Do not take Serdolect if you have untreated low levels of potassium or magnesium in the blood.

Contact your doctor if you have vomiting, diarrhea, electrolyte disturbances, or take medications to increase urine production. Your doctor may measure the amount of potassium in your blood.

•blood pressure monitoring
