Paxlovid is a prescription antiviral pill considered to be the most effective at-home treatment for Covid-19. It decreases the chances of hospitalization or death for high risk patients by 89%. 

If you test positive for Covid-19, you can get a prescription consultation from Dr. B, have the prescription delivered to your pharmacy, then take a course of 30 pills at home until you recover. Paxlovid is provided for free by the U.S. government for as long as Covid-19 continues to be a public health emergency.

Paxlovid must be taken within five days of the onset of Covid-19 symptoms.

Paxlovid is an at-home treatment for high-risk patients experiencing moderate to severe Covid-19 symptoms. You may be eligible for a prescription consultation if you:

In 2021, we launched the free Dr. B vaccine waitlist to match patients with providers who had extra vaccine doses. The goal was to get as many shots in arms as possible. Now we’re advancing our goal in a new way: by offering online prescription consultations for Paxlovid, the top at-home Covid-19 treatment. 

As part of our early-stage testing, these prescription consultations are currently free for New York, California and Florida residents. Paxlovid consultations will always be free for folks who qualify based on need, but in the future–as we expand to more states and a wide range of prescriptions–we'll charge a small doctor consultation fee.

According to the CDC, a small percentage of patients may experience “Paxlovid rebound” where Covid-19 symptoms briefly return 2-8 days after initial recovery. Researchers are still trying to understand why this is and whether it’s tied to Paxlovid or other factors. However the medication continues to be recommended as the most effective treatment for early-stage treatment of mild to moderate Covid-19 among high risk patients. 

For those that do experience rebound Covid-19, the symptoms are usually milder and there are no reports of progression to severe disease or a need for additional treatment. That being said, patients may still be contagious and will need to continue isolating to avoid passing the virus to others. 

We will continue to update this information as new data and guidance becomes available.

Patients take two doses each day, spaced 12 hours apart, for five days. A dose of Paxlovid contains two pink pills (Nirmatrelvir) and one white pill (Ritonavir). All three should be taken together. Pills should be swallowed with a full glass of water, not chewed, broken or crushed. 

It’s important to finish the full course of Paxlovid, even if symptoms begin to improve.

Paxlovid is typically well-tolerated. Any side effects are generally mild, and include the following: 

• Altered or impaired sense of taste
• Diarrhea
• Increased blood pressure
• Muscle aches

The following medications can be taken with Paxlovid, but may cause side effects. Paxlovid should only be taken with these medications if you are under the in-person supervision of your primary care doctor.
