CONTRAINDICATIONS

Table 3: Drugs That Are Contraindicated with Reyataz (atazanavir) (Information in the table applies to Reyataz with or without ritonavir, unless otherwise indicated)
  • Alpha 1-adrenoreceptor antagonist- alfuzosin: Potential for increased alfuzosin concentrations, which can result in hypotension.

  • Endothelin receptor antagonists-Bosentan: Plasma concentrations of atazanavir may be decreased when bosentan is administered with Reyataz without ritonavir. Coadministration of bosentan and Reyataz without ritonavir is not recommended.
  • PDE5 inhibitors: Use of PDE5 inhibitors for pulmonary arterial hypertension (PAH): Use of Revatio, (sildenafil) for the treatment of pulmonary hypertension (PAH) is contraindicated with Reyataz. The following dose adjustments are recommended for the use of Adcirca (tadalafil) with Reyataz: Coadministration of Adcirca in patients on Reyataz (with or without ritonavir): For patients receiving Reyataz (with or without ritonavir) for at least one week, start Adcirca at 20 mg once daily. Increase to 40 mg once daily based on individual tolerability. Coadministration of Reyataz (with or without ritonavir) in patients on Adcirca: Avoid the use of Adcirca when starting Reyataz (with or without ritonavir). Stop Adcirca at least 24 hours before starting Reyataz (with or without ritonavir). At least one week after starting Reyataz (with or without ritonavir), resume Adcirca at 20 mg once daily. Increase to 40 mg once daily based on individual tolerability.
