Does Telithromycin Interact with Paricalcitol?
CDI records a moderate classification for Telithromycin and Paricalcitol. The stored summary is: Strong CYP3A inhibitor that increases paricalcitol exposure. Dose adjustment may be necessary; monitor iPTH and serum calcium. The mechanism involves inhibition of cyp3a metabolism of paricalcitol. Patients taking both medications should consult their healthcare provider before starting, stopping, or changing the dosage of either drug. This record was extracted from drug labeling through openFDA. NIH/NLM RxNorm is used for drug identities. The summary and severity classification are CDI's processed information, not a verbatim source quotation. Product, route, and patient circumstances matter.
