Phenytoin Induced Anemia

Phenytoin - Wikipedia use has been associated with decreased bone density and increased bone fractures. Phenytoin induces metabolizing enzymes in the liver. This leads to increased metabolism of vitamin D, thus decreased vitamin D levels. Vitamin D deficiency, as well as low calcium and phosphate in the blood cause nbsp; Phenytoin and megaloblastic anemia- HELP . Student Doctor Network In FA 2007 it says that Phenytoin causes a megaloblastic anemia due to decreased folate absorption. I just took a pharm test on USMLERx and it gave me an answer to this same topic as the megaloblastic anemia being caused by decreased B12, reasoning being that Phenytoin screws with B12.

Sulfadoxine nbsp; Drug-Induced Hematologic Syndromes - Hindawi Antibiotics such as sulfasalazine and anticonvulsants such as phenytoin have been linked to folate-related changes which induce megaloblastic anemia, perhaps related to interference with absorption.

Drug-induced immune hemolytic anemia: MedlinePlus Medical Drug-induced immune hemolytic anemia is a blood disorder that occurs when a medicine triggers the body 39;s defense (immune) system to attack its own red blood cells. This causes red blood cells to break down earlier than normal, a process called hemolysis. Phenytoin-Folate Interactions - Journal of Applied Pharmaceutical phenytoin interaction and discusses the feasibility of using folate supplements to avoid such inadvertent drug folates by phenytoin induction of folate catabolic enzymes and inhibition of central appetite centers by megaloblastic anemia with anti-convulsant therapy as reported first by Mannheimer nbsp;

Should All Antiepileptic Drugs Be Given With Folic Acid? - Medscape Deficiency in adults has been associated with megaloblastic anemia and peripheral neuropathy. In addition, enzyme-inducing anticonvulsants, such as phenytoin, carbamazepine, primidone, and phenobarbital, are known to decrease folate levels, and valproic acid may interfere with folate metabolism. Megaloblastic Anemia: Practice Essentials, Pathophysiology, Etiology Megaloblastosis describes a heterogeneous group of disorders that share common morphologic characteristics: large cells with an arrest in nuclear maturation.

What is Phenytoin also can cause anemia. Folate Deficiency Epilepsy Foundation Folate deficiency is one of the causes of macrocytic anemia. It does not cause seizures, although it may involve the central nervous system, producing neuropsychiatric complications. 1 The association between folate deficiency and epilepsy involves common antiepileptic drugs (AEDs): Dilantin (Phenytoin): Side Effects, Interactions, Warning, Dosage There have also been rare reports of phenytoin induced dyskinesias, including chorea, dystonia, tremor and asterixis, similar to those induced by phenothiazine and other neuroleptic drugs. Cerebellar atrophy has been reported, and appears more likely in settings of elevated phenytoin levels and/or nbsp; Risk of Aplastic Anemia in Patients Using Antiepileptic Drugs Although carbamazepine (CBZ) and phenytoin (PHT)were suspected to be associated with aplastic anemia, the authors acknowledged they had insufficient data to evaluate this They were included in the multivariate model if they induced a 10 change in the crude OR for the exposure of interest.
