  2. Definition

    This codelist was taken from OpenCodelists, created by OpenSAFELY. We recommend viewing this Phenotype on the OpenCodelist website to view the most recent version.

    This codelist contains drugs which are likely to contraindicate the use of Paxlovid (nirmatrelvir/ritonavir). This list is a refinement of previous "do not co-administer" lists to filter out drugs where mitigation strategies may be employed - e.g. withholding the drug during Paxlovid therapy. See GitHub issue for full details.
