Paxlovid is also contraindicated with medicinal products that are highly dependent on CYP3A for clearance and for which elevated plasma concentrations are associated with serious and/or life-threatening reactions. Paxlovid is also contraindicated with medicinal products that are potent CYP3A inducers, where significantly reduced plasma nirmatrelvir/ritonavir concentrations may be associated with the potential for loss of virologic response and possible resistance. Medicinal products listed in Table 8 and Table 10 (see Interactions) are a guide and not considered a comprehensive list of all possible medicinal products that may be contraindicated with Paxlovid. (See Table 8.)
