Anticoagulants: Patients on anticoagulants such as warfarin should be carefully monitored during anabolic steroid therapy as anabolic steroids may increase sensitivity to oral anticoagulants which may require a concomitant reduction in anticoagulant dosage to achieve a desirable prothrombin time (PT). Anticoagulant patients should be monitored regularly during anabolic steroid therapy, particularly during initiation and termination of therapy. Warfarin patients should have INR and PT monitored throughout androgen therapy and warfarin dosages titrated to achieve the desired INR and PT. Such patients should be monitored for occult bleeding.
In either case, both men and women, Anavar can be used for far longer than most oral anabolic steroids due to its low liver toxicity rating and further as it does not appear to taper off in benefit as fast as many other oral anabolic steroids. The majority of Anavar users will supplement for 6-8 weeks but longer durations of 12 weeks are not uncommon, especially during female contest preparation time. Keep in mind, the leaner you are the greater the results will be, meaning, they will be far more pronounced; for this reason most women will choose Anavar during the latter half of their diet to reap the greatest reward.
