Paxlovid is an antiviral prescription medication intended for the treatment of mild to moderate COVID-19 (coronavirus disease 2019) infections. It should be given only to persons who test positive for SARS-CoV-2, and not as a preventive medication.

Paxlovid consists of two different medications:
●    Nirmatrelvir, which inhibits the SARS-CoV-2 protein to stop the virus from replicating.
●    Ritonavir, which slows the breakdown of nirmatrelvir to help it remain in the body longer at a higher concentration.

Paxlovid medication is recommended for symptomatic patients with mild to moderate COVID-19 who also have one or more serious risk factors for progression to severe disease. The medication is taken orally, either with or without food. Treatment normally begins within five days of the patient's first COVID symptoms, and continues for five days afterward.

In May 2023, the U.S. Food and Drug Administration (FDA) granted full approval to Paxlovid as an antiviral drug for treating COVID-19 in adults.

Only about 1 percent of patients experience significant side effects from Paxlovid. The most common side effects reported are dysgeusia (alteration in the sense of taste) and diarrhea. More severe reactions are possible. If you experience any uncomfortable side effects from Paxlovid, contact your doctor immediately.

Treatment consists of three tables: two 150 mg tablets of nirmatrelvir and one 100 mg tablet of ritonavir. All three tablets are taken orally at the same time, twice per day for five days.

Use of Paxlovid as a Covid medication is not authorized for longer than five consecutive days.

There are more than a few medications that are contraindicated with Paxlovid, and may lead to serious and even life-threatening reactions when the two drugs are used together. These medications include but are not limited to certain antipsychotics (such as pimozide), migraine medications (such as eletriptan), PDE5 inhibitors (such as sildenafil), sedatives (such as triazolam and oral midazolam), and St. John’s wort. Be sure to tell your medical provider about all medications you are currently taking.

In addition, patients should not use Paxlovid if they are hypersensitive to either of its active ingredients, nirmatrelvir and ritonavir
