Calan can influence thinking or reactions, thus special carefulness is necessary during driving or actions requiring concentration of attention and fast reaction. Do not get up too fast if you sit or lie as it may cause dizziness. Avoid drinking alcohol and consult your doctor if you drink grapefruit juice as its interaction with Calan may lead to potentially dangerous effects.
Hypersensitivity, severe arterial hypotension pregnancy, breast-feeding, atrioventricular block (first and second degree), sinoatrial blockade, sick sinus syndrome (except of the patients with a cardiostimulator), Wolff-Parkinson-White syndrome (WPW), Lown-Ganong-Levine syndrome in combination with atrial fibrillation/flutter. Some other conditions require careful use of Calan. Do not take the medication unless it is prescribed to you and take it only as it is administered by your physician.
