Consumer information for this interaction is not currently available.GENERALLY AVOID: Tofacitinib has been shown to decrease heart rate and prolong the PR interval of the electrocardiogram in some patients. Theoretically, coadministration with other agents that prolong the PR interval (e.g., beta-blockers, digoxin, alpha-2 adrenoceptor agonists) may result in elevated risk of conduction disturbances and atrioventricular block. In clinical trials, use of tofacitinib (10 to 20 mg daily; at steady-state) was associated with significant decreases in heart rate (4 to 7 bpm) and increases in PR interval (4 to 10 ms) compared with placebo. MANAGEMENT: According to the manufacturer, concomitant use of tofacitinib with other agents that lower heart rate and/or prolong the PR interval should be avoided when possible. Caution is advised if concomitant use is necessary, particularly in patients with known conduction problems or severe cardiac disease. An ECG should be considered in these patients before initiating concomitant therapy and after titration to steady-state. Patients should be advised to notify their physician if they experience dizziness, lightheadedness, fainting, or irregular heartbeats. References Canadian Pharmacists Association "e-CPS.
