• zanubrutinib

  Monitor Closely (1)cyclosporine will increase the level or effect of zanubrutinib by affecting hepatic/intestinal enzyme CYP3A4 metabolism. Modify Therapy/Monitor Closely. Reduce zanubrutinib (a CYP3A4 substrate) to 80 mg PO BID to when coadministered with a moderate CYP3A4 inhibitor. Interrupt dose as recommended for adverse reactions. After discontinuing the CYP3A4 inhibitor, resume previous dose of zanubrutinib.

• ziprasidone

  Minor (1)cyclosporine will increase the level or effect of ziprasidone by affecting hepatic/intestinal enzyme CYP3A4 metabolism. Minor/Significance Unknown.

• zoster vaccine live

  Serious - Use Alternative (1)cyclosporine decreases effects of zoster vaccine live by pharmacodynamic antagonism. Contraindicated. Avoid live vaccines in immunocompromised patients due to the risk of developing a clinical infection from the live vaccine. Inadequate immune response to the vaccine may also occur in the presence of immunosuppressants. Avoid live vaccines for at least 3 months after cessation of immunosuppressant therapy unless the benefit of vaccine administration outweighs the potential risk.

• zoster vaccine recombinant

  Monitor Closely (1)cyclosporine decreases effects of zoster vaccine recombinant by pharmacodynamic antagonism. Modify Therapy/Monitor Closely. If possible, complete all age-appropriate vaccinations at least 2 weeks before initiating immunosuppressant therapy. Patients vaccinated <14 days before starting immunosuppressive therapy or during immunosuppressive therapy should be revaccinated at least 3 months after therapy is discontinued if immune competence has been restored. Longer waiting periods may be required for drugs that maintain their immunosuppressive effects for more than 3 months after discontinuation (eg, ocrelizumab). .
