What Are The Possible Drug Interactions of Rithmo?

  1. Statins (HMG-CoA reductase inhibitors): Rithmo can increase the levels of statins in the blood, leading to an increased risk of statin-related side effects, including muscle pain and weakness. Statins affected by this interaction include atorvastatin, simvastatin, and lovastatin.
  2. Warfarin: Rithmo may enhance the anticoagulant effect of warfarin, leading to an increased risk of bleeding. If you are taking warfarin, your doctor may need to adjust your dosage and monitor your blood clotting time more closely.
  3. Theophylline: Rithmo can increase the levels of theophylline, a medication used to treat respiratory conditions. This can lead to theophylline toxicity. Dosage adjustments may be necessary.
  4. Digoxin: Rithmo may increase the levels of digoxin in the blood, potentially leading to digoxin toxicity. If you are taking digoxin, your doctor may need to monitor your levels closely and adjust your dosage.
  5. Colchicine: Rithmo can increase the levels of colchicine, leading to an increased risk of colchicine toxicity. This can be especially dangerous in individuals with kidney or liver problems.
  6. Certain anticoagulants: Rithmo may enhance the effects of certain anticoagulant medications, increasing the risk of bleeding.
  7. Ergotamine and dihydroergotamine: Concurrent use of Rithmo with these medications can lead to ergot toxicity, characterized by symptoms such as numbness, tingling, cold extremities, and potentially serious complications.
  8. Carbamazepine: Rithmo may increase the levels of carbamazepine, potentially leading to carbamazepine toxicity.
  9. Cisapride and pimozide: Rithmo can increase the risk of serious cardiac arrhythmias when used with these medications.
