  • Children < 12 years: There is no evidence for the efficacy and safety of flunarizine in these people. Flunarizine is not recommended for children  < 12 years.
    Dosage in patients with hepatic impairment
  • Because the drug is metabolized in the liver with a large extent, it is necessary to adjust the dose in these patients. The starting dose of 5 mg/day, taken in the evening.

  • Preexisting symptoms of Parkinson's disease before treatment.

  •  Dry mouth.


  • Nausea, stomach pain.
  • Galactorrhoea.


  • Anxiety.
  • Rash.
  • Muscle ache.


  • The recommended dose should not be exceeded. Patients should be seen at regular intervals, especially during maintenance treatment, so that extrapyramidal or depressive symptoms may be detected early and if so, treatment discontinued.
  • In rare cases fatigue may increase progressively during flunarizine therapy. In this event, the therapy should be discontinued.
  • If during maintenance treatment, the therapeutic effects are subside, treatment should also be discontinued.
  • Accumulation may occur if given at dose levels higher than recommended, with an increased incidence of side effects.
  • Fluzinstad contains lactose. Patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption should not use this medicine.
  • Pregnancy: There are no data from the use of flunarizine in pregnant women. Animal studies do not indicate direct or indirect harmful effects with respect to pregnancy, embryonal/foetal development, parturition or postnatal development. As a precautionary measure, it is preferable to avoid the use of flunarizine during pregnancy.
  • Lactation: Animal studies have shown excretion of flunarizine in breast milk. It is unknown whether flunarizine is excreted in human milk. A decision on whether to discontinue breast-feeding or to continue/discontinue therapy with flunarizine should be made taking into account the benefit of breast-feeding to the child and the benefit of therapy to the woman.
  • Effects on ability to drive and use machines: Since somnolence may occur, especially at the start of the treatment, caution should be exercised during activities such as driving or operating dangerous machinery.
