Theoretically, selenium might prolong the sedating effects of barbiturates.<br> Laboratory research suggests that selenium can inhibit the hepatic metabolism of barbiturates (14601,14602). Selenium seems to prolong the sedative effect of pentobarbital in animal models (14601).

Selenium may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.<br> Clinical research suggests that taking selenium 10 mcg/kg/day can increase bleeding times by increasing prostacyclin production, which inhibits platelet activity (14540). Other clinical research suggests that taking selenium 75 mcg daily, in combination with ascorbic acid 600 mg, alpha-tocopherol 300 mg, and beta-carotene 27 mg, reduces platelet aggregation (74406).

Theoretically, selenium might interfere with warfarin activity. <br> Animal research suggests that selenium can increase warfarin activity. Selenium might interact with warfarin by displacing it from albumin binding sites, reducing its metabolism in the liver, or by decreasing production of vitamin K-dependent clotting factors (14541). Selenium can also prolong bleeding times in humans by increasing prostacyclin production, which inhibits platelet activity (14540).

Theoretically, selenium supplementation may reduce the effectiveness of immunosuppressant therapy. <br> In vitro research and preliminary clinical evidence suggests that selenium may stimulate the immune system (74483,74445).

Contraceptive drugs might increase levels of selenium, although the clinical significance of this effect is unclear.<br> Some research suggests that oral contraceptives increase serum selenium levels in women taking oral contraceptives; however, other research shows no change in selenium levels (14544,14545,14546,101343). It is suggested that an increase could be due to increased carrier proteins, indicating a redistribution of selenium rather than a change in total body selenium (14545).

Selenium might reduce the beneficial effects of niacin on high-density lipoprotein (HDL) levels. <br> A combination of niacin and simvastatin (Zocor) effectively raises HDL cholesterol levels in patients with coronary disease and low HDL levels. Clinical research shows that taking a combination of antioxidants (vitamin C, vitamin E, beta-carotene, and selenium) along with niacin and simvastatin (Zocor) attenuates this rise in HDL, specifically the HDL-2 and apolipoprotein A1 fractions, by more than 50% in patients with coronary disease (7388,11537). It is not known whether this adverse effect is due to a single antioxidant such as selenium, or to the combination. It also is not known whether it will occur in other patient populations.
