Drugs that interfere with vitamin D absorption

*Check with your doctor before taking vitamin D supplements if you have digestive problems. The problem may be more serious than just a lack of vitamin D.
-Barbiturates
-Carbamazepine
-Cholestyramine
-Colestipol
-Fosphenytoin
-H2 blockers: Tagamet, Pepcid, Axid, Zantac
-Heparin

-Isoniazid
-Mineral oil or products containing mineral oil
-Orlistat
-Phenobarbital
-Phenytoin
-Rifampin
-St. John’s wort
-Steroids such as prednisone and cortisol don’t prevent absorption of vitamin D, but they do affect the metabolism of vitamin D so that less active vitamin D is formed.
