Heart Home > Rythmol Drug Interactions
Your healthcare provider may need to monitor you closely if you take Rythmol with any other medication that can cause QT prolongation (a certain change in the heart rhythm), due to the risk of a life-threatening abnormal heartbeat (heart arrhythmia).
Orlistat may decrease the amount of Rythmol absorbed into the body from the gastrointestinal (GI) tract. There have been reports of people experiencing severe side effects after abruptly stopping orlistat during Rythmol treatment. If you take orlistat, make sure to let your healthcare provider know. Also, do not suddenly stop taking it without talking to your healthcare provider.
Rythmol may increase blood levels of theophylline, potentially increasing your risk for theophylline toxicity. Talk to your healthcare provider about this potential interaction before taking these medicines together.
Rythmol may increase blood levels of venlafaxine, potentially increasing the risk for side effects. Talk to your healthcare provider about this potential interaction before taking these drugs together.
Rythmol has been shown to increase warfarin blood levels, potentially increasing the risk for serious side effects, including bleeding. Your healthcare provider may need to adjust your warfarin dosage based on your prothrombin time ("protime" or PT) and international normalized ratio (INR) when you first start or stop using Rythmol.
