So I can find it again: this government of Quebec webpage (in English) has two lists of drug interactions for Paxlovid. The first, which I've seen elsewhere, are "do not take Paxlovid if you are taking any of these other drugs." The second, longer, list is other things that may interact with Paxlovid. In some cases, taking Paxlovid increases or decreases the effective dose of the other medication.

https://vaccin-covid.canada.ca/info/paxlovid-en.html and scroll down to "The following may also interact with PAXLOVID"

ETA: And the US FDA EUA includes a different list of drug interaction warnings: https://www.fda.gov/media/155050/download (via [personal profile] siderea) The UK has yet a third list. All of this seems to add up to "talk to your physician about whetber to take this, and about dosage of your other medications."


More about Paxlovid, not closely related but I already have one post today to keep track of this stuff:

The company that makes the drug did a study of whether it would prevent infection in people who live in the same household as someone with covid, and it doesn't seem to. (The study was of 2957 adults, who tested negative and did not have covid symptoms.) "Doesn't seem to" in this case means that there was a difference, but it's not statistically significant.

Also, something I hadn't known is that all the Paxlovid studies so far are in unvaccinated people. I got that part from a blog post by Derek Lowe. That might be relevant for the vast majority of my readers, who are vaccinated and have useful antibodies because it, though it won't affect my own decision-making.

Anecdotally amongst some folks with long covid and a new covid infection, Paxlovid suppresses covid-y symptoms for the days it's taken, and then often the symptoms resume/rebound. They've speculated that the few days they're to take it aren't enough for an immune response to gather itself properly.

Some LC folks have measurable antibodies from prior infection, and some don't (reasons various).
