First, because both agents inhibit dihydrofolate reductase, 4, 5 the combination of these 2 drugs substantially reduces folate metabolism and increases the potential for myelosuppression.. (self 1975) Hypothroidism does the opposite, however, not a concern if the patient is receiving long term thyroid hormone therapy synthroid and is euthyroid*. Common interactions include diarrhoea among females and dyspnoea among males. Shalansky S, Lynd L, Richardson K, Ingaszewski A, Kerr C. Warfarin is a medication used in the prophylaxis and treatment of venous thrombosis and thromboembolic events. Review on mechanisms and interactions in concomitant use of herbs and warfarin therapy. Although the mechanism for this interaction is not fully known, it is suspected that a decrease in vitamin K-producing gut flora with resulting vitamin K deficiency would be the most likely contributing factor. Common interactions include cellulitis among females and dyspnoea among males. Abstract A 72-year-old man had been taking warfarin for a pulmonary embolus and recurrent deep-vein thromboses. There is really no more "classic" drug-drug interaction than Bactrim and Warfarin. A 5- to 6-fold increase in warfarin dose was prescribed to reach therapeutic international normalized ratios (INRs), but even these increases were insufficient to maintain his INR in the therapeutic range.. Additional treatment, hospitalization, or an extended hospital. 025) and low baseline INR value (P=0. Severity - Moderate: The effects may cause deterioration in a patient's clinical status. 1k views Answered >2 years ago Thank 1 thank Dr. It is in the anticoagulant class of drugs. Arch Intern Med 1984; 144: 2413–2414 Although the mechanism for this interaction is not fully known, it is suspected that a decrease in vitamin K-producing gut flora with resulting vitamin K deficiency would be the most likely contributing factor. Documentation: interaction is suspected, probable or established. An objective causality assessment revealed that this adverse drug bactrim and warfarin interaction mechanism event as a result of the warfarin and AM/CL interaction was possible Severity - Major: The effects are potentially life-threatening or capable of causing permanent damage. The possible mechanism of an interaction may be dose-related inhibition of warfarin metabolism, and may be more pronounced in patients with decreased renal clearance of fluconazole. Warfarin exists as a mixture of two stereoisomers S(−) and R(+) Sato RI, Gray DR, Brown SE, Warfarin interaction with erythromycin. It just hits on so many levels. Multivariate analysis showed that high maintenance dose (>40 mg/week) of warfarin (P=0.
