- Xocova is a new five-day pill that can prevent COVID-19 after you’ve been exposed — not treat it once you’re already sick — and it’s now available in the U.S. by prescription.
- COVID-19 test positivity is running near 5% nationally, with cases rising in nearly all 50 states, though this summer’s surge is milder so far than last year’s.
- Xocova has to start within 72 hours of exposure to work, so calling your doctor right after a known exposure — not days later — is what makes it useful.
- Xocova has real drug interactions and isn’t right for everyone; a quick conversation with your doctor about your other medications is essential before starting it.
If someone in your house just tested positive for COVID-19, there’s a new option worth knowing about: Xocova, the first oral medication approved in the U.S. specifically to help prevent COVID-19 after an exposure45. It arrives at a relevant moment — COVID-19 case activity is climbing across the country again this August1. Here’s what the current numbers actually show, and everything you need to know about whether Xocova makes sense for your family.
How bad is the current COVID surge, exactly?
COVID-19 test positivity crossed 3% in early August for the first time since March, and by mid-August it was running close to 5% nationally, with the CDC estimating cases are growing in nearly every state13. For comparison, this same week last year, positivity was over 9% — so while this wave is real and still climbing, it’s tracking milder than 2025’s1. The CDC still classifies national COVID-19 activity as low overall, even as it rises2. Peak transmission for this wave isn’t expected until closer to September1. The South and West are seeing the steepest climbs right now, which tracks with how summer waves have typically spread in past years — but with school starting back up and households spending more time in close quarters, exposures are becoming harder to avoid no matter where you live.
What is Xocova, and how is it different from Paxlovid?
Paxlovid treats an active COVID-19 infection in someone who’s already sick. Xocova does something different: it’s approved as post-exposure prophylaxis, meaning it’s for people who are not yet infected but were recently exposed to someone who is, to help stop an infection from taking hold in the first place4. In its approval trial, Xocova cut the risk of developing symptomatic COVID-19 by 67% in exposed people who took it, compared with placebo4. The FDA approved it in May 2026, and it became available at U.S. pharmacies shortly after45.
Who qualifies for Xocova, and how is it taken?
Xocova is approved for adults and adolescents 12 and older who’ve had close contact with someone confirmed to have COVID-194. It has to begin within 72 hours of that exposure to work, and you typically need a negative COVID-19 test first to confirm you’re not already infected6. The regimen is short: three tablets together on day one, then one tablet daily on days two through five4. That 72-hour window is the whole reason this is a “call your doctor today” situation rather than a “figure it out next week” one — waiting even a couple of extra days can put Xocova out of reach.
Are there risks or interactions to know about?
Yes, and they’re significant enough to take seriously. Xocova strongly affects how your body processes certain other medications, including some statins, sedatives, and other commonly prescribed drugs, and combining it with the wrong medication can be dangerous6. It’s contraindicated with several drug classes entirely, and anyone who could be pregnant should confirm pregnancy status before starting it6. Most people tolerate it well, with side effects generally limited to things like mild diarrhea or changes in taste, but the medication interaction list is long enough that it matters even if you’re generally healthy and only take one or two other prescriptions6. This is exactly why Xocova isn’t something to start on your own after a quick search — your doctor needs to check it against your current medication list first.
Call or text our Vienna, VA office right away. Because Xocova only works within 72 hours of exposure, we can often review your medications and get you a same-day or same-week appointment to see if it’s a fit — together.
Frequently asked questions
Is Xocova the same thing as Paxlovid?
No. Paxlovid treats an active infection. Xocova is taken after an exposure, before you test positive, to help prevent infection from developing in the first place4.
How soon after exposure do I need to start Xocova?
Within 72 hours of contact with someone who has COVID-19. The sooner you start within that window, the better it can work6.
Is the current COVID surge worse than last year’s?
No, not so far. Weekly test positivity is running lower than this time last year, even though cases are climbing in nearly every state1.
Can I get Xocova without talking to a doctor first?
No. It’s prescription-only, has serious interactions with certain other medications, and requires a pregnancy check for some patients — all things your doctor needs to review with you first6.
