Rabeprazole Genetic Information

CYP2C19 is an enzyme in the blood that is responsible for breaking down rabeprazole and other drugs in the body. Some patients have less of this protein in their bodies, affecting how much of the drug gets eliminated. Levels of CYP2C19 can vary greatly between individuals, and those having less of this protein are known as "poor metabolizers." 

CYP2C19 testing is done to determine whether you are a poor metabolizer. If you are a poor metabolizer, the levels of rabeprazole in your blood can become too high. As a result you may be at an increased risk of having more side effects from rabeprazole. 

Your doctor may adjust your dose of rabeprazole if you are a poor metabolizer.
