Consumer:

Consumer information for this minor interaction is not currently available. Some minor drug interactions may not be clinically relevant in all patients. Minor drug interactions do not usually cause harm or require a change in therapy. However, your healthcare provider can determine if adjustments to your medications are needed.

Professional:

Since raltegravir solubility is increased at higher pH, coadministration with agents that elevate gastric pH may theoretically increase the plasma concentrations of raltegravir. However, concurrent use of proton pump inhibitors or H2-receptor antagonists in clinical trials did not result in meaningful differences in the safety of raltegravir. Based on these data, no dosage adjustment of raltegravir is necessary when used together with proton pump inhibitors or H2-receptor antagonists.
