Understand Your Risk for Side Effects with Rxight® Genetic Testing
When treated with metoclopramide, people who lack NADH-cytochrome b5 reductase< enzyme, are more susceptible to develop some side effects (methemoglobinemia and sulfhemoglobinemia) according to the Reglan Guide. Also, individuals with genetic variations in some genes, CYP2D6, KCNH2, and 5-HT4 receptor (HTR4) gene have been reported to experience more adverse reactions.
