Paxlovid is also contraindicated with medications that, conversely, strongly induce all those identical enzymes, leading to the quicker breakdown of nirmatrelvir or ritonavir, as reduced concentrations of nirmatrelvir or ritonavir could be linked with most likely dropping virologic response and creating viral resistance. Paxlovid simply cannot be commenced instantly soon after discontinuing these prescription drugs since the consequences of all those prescription drugs continue being soon after discontinuation.
