  • When administered to pregnant rabbits during organogenesis from gestation day 6 to 20, an increased incidence of cardiac malformations (cardiac ventricular septal defect), major vessel malformations (truncus arteriosus communis), late spontaneous abortions and resorptions occurred with vericiguat doses of 4 times or more than the human exposure at the maximum recommended human dose (MRHD). (pdr.net)
  • Patients on warfarin might need to reduce their anticoagulant dose or monitor their prothrombin time more closely while taking atovaquone-proguanil, although coadministration of these drugs is not contraindicated. (cdc.gov)
  • If people with warfarin sensitivity take the average dose (or more) of warfarin, they are at risk of an overdose, which can cause abnormal bleeding in the brain, gastrointestinal tract, or other tissues, and may lead to serious health problems or death. (medlineplus.gov)
  • Individuals develop warfarin sensitivity because a lower warfarin dose is needed to inhibit the VKORC1 enzyme, as there is less functional enzyme that needs to be suppressed. (medlineplus.gov)
Deep venous thr1

Cyclosporine2
  • Amiodarone, cyclosporine, or thyroid hormones (eg, levothyroxine) because their effectiveness may be decreased by Alli. (buypills24h.com)
  • Cyclosporine because its effectiveness may be severely decreased by Xenical. (reductil-shop.com)
Anticoagulant effects2
  • Since warfarin does not affect the activity of previously synthesized and circulating coagulation factors, depletion of these mature factors through normal catabolism must occur before the anticoagulant effects of the drug are observed. (medscape.com)
