<p>Patients with heart failure should be treated with caution. An increased risk of a further deterioration of the ventricular pump function cannot be excluded. Since the abrupt withdrawal of bisoprolol may lead to a transitory worsening of the clinical condition, especially in patients with ischemic heart disease, the treatment must not be stopped abruptly. Caution is advised in patients with impaired hepatic function. Beta-blockers should be avoided in patients with obstructive airways diseases unless there are compelling clinical reasons for their use. Due to the bisoprolol component treatment must be used with caution in: bronchospasm (bronchial asthma, chronic obstructive airways disease; concomitant bronchodilating therapy may be recommended); diabetes mellitus showing large fluctuations in blood glucose values, symptoms of hypoglycemia can be masked; strict fasting; ongoing desensitization therapy; first degree AV block; Prinzmetal&rsquo;s angina; peripheral arterial occlusive disease. Patients with psoriasis or with a history of psoriasis should only be given beta-blockers (e.g. bisoprolol) after a careful balancing of benefits and risks. Symptoms of thyrotoxicosis may be masked. In patients undergoing general anesthesia, the anesthetist must be aware of beta-blockade. If it is thought necessary to withdraw beta blocker therapy before surgery, this should be done gradually and completed about 48 hours before anesthesia.</p>
