In The label of Reyataz is reported that the antacids are non advised due the interactions.He in many years he have changed many terapies and developed resitance to some meds (i.e Sustiva is one). This is last regime after many others. Yous lab tests are not optimale because have low CD4 around 150 end VL is undetectable. He tell me that your cd4 are always low and never go up also with past regimes I want help he to regularize for the best time to take Reyataz to minimixe if possible the interactions. Thanks. Marcello.

In general it is not recommended to use those drugs together because if a negative effect on atazanvir absorption. Some patients can have OK levels of atazanavir even when taking a proton pump inhibitor or other potent acid reducer such as rabeprazole. Checking the atazanavir level may be worth doing if those drugs are used together. Switching the atazanavir to Lexiva, Kaletra, Invirase, or Prezista may be an option for many patients who require aggressive stomach acid reduction since those drugs are not as impacted as atazanavir. Separating the Reyataz dosing by at least 12 hours from the rabeprazole may be advisable if those drugs are used together. KH
