- Cinnarizine can cause drowsiness, especially at the start of treatment. Therefore, caution should be used if other drugs that depress brain function are administered. Driving and using machines should also be avoided if drowsiness occurs.
- The intake of cinnarizine can alter the results of diagnostic tests performed on the skin; if taken up to four days before the test, in particular, it can inhibit positive reactions.
- Drugs capable of depressing the central nervous system, such as, for example, anxiolytics;

The use of the active principle in the treatment of cerebral circulation disorders and peripheral vasculopathies is justified precisely by its calcium-antagonist action.
In fact, cinnarizine, by blocking the calcium channels, is able to inhibit the contractions of the smooth vascular muscle cells. Furthermore, the active principle in question is able to decrease the contractile activity of vasoactive substances - such as norepinephrine (or noradrenaline, if you prefer) and serotonin - by blocking the calcium channels dependent on receptors.
It should be noted that the blocking of calcium entry into the cell is tissue-selective and allows cinnarizine to prevent vessel constriction without however affecting blood pressure and heart rate.
To all this is added the ability of the active principle to improve insufficient microcirculation by increasing erythrocyte deformability and decreasing blood viscosity.
Cinnarizine is also useful in the treatment of balance alterations as it is capable of inhibiting the stimulation of the vestibular system with suppression of nystagmus and other autonomic disorders. Even acute episodes of vertigo can be reduced or prevented with the use of the active ingredient. .
