Paxlovid has been shown in clinical trials to reduce the risk of hospitalization and death from COVID-19 by nearly 90% in high-risk patients. Despite its effectiveness, this oral antiviral treatment is not suitable for everyone, and it is crucial to understand who should not take Paxlovid due to significant risks associated with certain health conditions and drug interactions.

In late 2021, the U.S. Food and Drug Administration (FDA) authorized the first oral antiviral treatments for COVID-19, Paxlovid and Lagevrio, for high-risk patients to help prevent severe illness. Understanding **what is the difference between Paxlovid and Lagevrio** is crucial for patients, as these medications vary significantly in their mechanisms of action, overall effectiveness, potential for drug interactions, and eligibility criteria.

Based on analysis of FDA adverse event data, Paxlovid has been associated with a higher number of neurologic-related adverse events compared to other COVID-19 medications used to treat the virus. So, **does Paxlovid affect the nervous system**? The answer is yes, though primarily with mild and often transient symptoms, with the potential for more significant effects due to drug interactions.

Paxlovid carries an FDA-issued boxed warning, the agency's most serious type, due to significant and potentially life-threatening drug interactions [1.2.4, 1.3.2]. If you're asking, **'What is the black box warning on Paxlovid?'**, it's crucial to understand these risks before starting treatment.

In a real-world study, adults who took Paxlovid within five days of a COVID-19 diagnosis had a 51% lower hospitalization rate [1.2.2]. However, this antiviral medication is not suitable for everyone, and it's crucial to understand **who should avoid taking Paxlovid** to prevent serious health risks.

Over 605 million COVID-19 infections were reported globally by early 2023, underscoring the ongoing need for effective treatments. For high-risk patients, a critical question arises: **Is remdesivir like Paxlovid?** While both are effective antivirals for combating SARS-CoV-2, they are fundamentally different drugs, with distinctions in their mechanisms, administration, and optimal use cases.

The primary active component of Paxlovid, nirmatrelvir, has an average half-life of 6.05 hours, leading to a typical total elimination time of 24–30 hours for how long does Paxlovid take to get out of your system. This rapid clearance, however, can be influenced by several factors, including a patient's kidney function and other medications they may be taking.

According to the U.S. Food and Drug Administration (FDA), an altered sense of taste and **diarrhea** are among the most commonly reported side effects for people taking the COVID-19 antiviral Paxlovid. This five-day treatment course can cause temporary gastrointestinal discomfort, though the side effects typically subside after completing the medication.

Studies show Paxlovid can reduce the risk of severe COVID-19 by over 50%, and up to 89% in unvaccinated individuals [1.2.1]. A key question for patients is, **how long does it take for Paxlovid to get out of your system** after completing the 5-day course?

According to a 2023 study involving over 150,000 patients, the risk of acute liver injury was not increased during the 5-day Paxlovid treatment period compared to the pre-treatment period. This suggests that liver damage from Paxlovid is uncommon, especially in individuals without pre-existing liver disease.
