Background Initiation of fingolimod treatment is associated with a transient decrease of heart rate, and atrioventricular ( AV ) conduction block may occur. Objective To evaluate the therapeutic effect and safety of fingolimod treatment in MS patients in Denmark with focus on cardiac and pulmonary side effects at treatment onset. Materials & methods We analysed data from the first 496 fingolimod‐treated Danish patients, observed for at least 3 months. In a subset of 204 patients, we monitored cardiac and pulmonary adverse effects following treatment initiation. Results The overall annualized relapse rate ( ARR ) was 0.37 (95% CI 0.31–0.44); 0.22 (95% CI 0.03–0.81) in de novo ‐treated patients, 0.29 (95% CI; 0.23–0.37) in patients switching from IFN ‐beta or GA and 0.46 (9 5% CI 0.34–0.60) after natalizumab. In the subset of 204 patients, 8 (3.9%) required prolonged cardiac monitoring due to bradycardia and/or second‐degree AV block type I. All patients recovered spontaneously. Two patients discontinued fingolimod. Eleven (5.4%) patients reported respiratory complaints and two of these patients discontinued treatment. Conclusions Fingolimod appears to be safe and effective in MS patients in a clinical setting. Mild cardiac adverse effects occurred at a similar rate as in clinical trials.
