This article was reviewed by a member of Caltech's Faculty. Antivirals are medications used specifically to treat viral infections. They aim to minimize the symptoms of an infection and shorten its duration.
They also can help reduce transmission of a virus. Rather than killing a virus directly, antivirals usually suppress the virus's ability to infect and multiply in your cells. These drugs often work by inhibiting molecular interactions and functions needed by the virus to produce new copies of itself.
The way a drug produces its therapeutic effect is called its mechanism of action. Antivirals are often delivered in combinations that have different mechanisms of action.
This helps to prevent the emergence of mutated drug-resistant viral strains that can bypass the effects of a single drug. For example, combination antiviral therapy is now the standard of care in HIV and hepatitis C virus infections.

Prrvention earlier the better. Antiviral prevrntion should be taken within the first 48 hours of the symptom onset as this is a key period to inhibit the replication of the virus. The effectiveness of the antivirals decreases with the time elapsed from the symptom onset.
Early administration of antivirals after contracting an influenza infection has greater benefits. Adamantanes are not active against influenza B strains and there is widespread resistance among H1N1 and H3N2 influenza A strains. None of these medications can be obtained without a prescription.
Zanamivir and oseltamivir belong to the neuraminidase inhibitor family of drugs that attack the flu virus replication cycle and prevent its spreading within the body.
Baloxavir marboxil inhibits the viral polymerase acidic protein resulting in disruption of viral RNA transcription and virus replication.
Similarly, as neuraminidase inhibitors, baloxavir can also be used for treatment of patients aged one year and above. Their introduction is therefore an important addition to the other tools we have to prevent and treat influenza infection.
There are good reasons for this. If doctors use antivirals a lot, then the influenza viruses that are circulating may develop resistance to them.
Also, like many other medicines, antivirals against influenza should be prescribed by doctors based on their clinical assessment and in adherence to national guidelines and recommendations. An excessive, inappropriate use of antivirals may also affect their availability during crises e.
an influenza pandemic. Some European countries have policies in place that allow or recommend doctors to use antivirals against influenza only when it has been shown that influenza is circulating in the population at a certain level.
Antivirals like zanamivir, oseltamivir and baloxavir marboxil should only be used on medical prescription and under medical supervision. This may happen in special circumstances where people in a risk group have been exposed to influenza.
The most common situation is when there is a proven influenza outbreak in a long-term care facility, a nursing home or a hospital ward.
Then antivirals may be given to all the people at risk as early treatment or prophylaxis.

Page last updated 25 May Most people with COVID have mild illness and can recover at home. You can treat symptoms with over-the-counter medicines, such as acetaminophen or ibuprofen, to help feel better. If you have COVID and are more likely to get very sick from COVID, treatments are available that can reduce your chances of being hospitalized or dying from the disease. Medications to treat COVID must be prescribed by a healthcare provider or pharmacist and started within 5—7 days after symptoms appear. Contact a healthcare provider right away to determine if you are eligible for treatment, even if your symptoms are currently mild. Being vaccinated makes you much less likely to get very sick. But studies have shown that vaccinated people, especially those at risk for severe illness, including those ages 65 and older, may still benefit from treatment. A healthcare provider will help decide which treatment, if any, is right for you. Check with your healthcare provider or pharmacist if you are taking other medications to make sure the COVID treatments can be safely taken at the same time. FDA has authorized or approved several antiviral medications used to treat mild to moderate COVID in people who are more likely to get very sick. The National Institutes of Health NIH provides COVID Treatment Guidelines for healthcare providers to help them work with their patients and determine the best treatment options for them. Several options are available for treating COVID They include:. Nirmatrelvir with Ritonavir Paxlovid Antiviral. Remdesivir Veklury Antiviral. Molnupiravir Lagevrio Antiviral. When Start as soon as possible; must begin within 5 days of when symptoms start. When Start as soon as possible; must begin within 7 days of when symptoms start. How Intravenous IV infusions at a healthcare facility for 3 consecutive days. Some treatments might have side effects or interact with other medications you are taking. Ask a healthcare provider if medications to treat COVID are right for you. If you are hospitalized, your healthcare provider might use other types of treatments, depending on how sick you are. These could include medications to treat the virus, reduce an overactive immune response, or treat COVID complications. If you have a weakened immune system , have received antiviral treatment, and continue to experience COVID symptoms, your healthcare provider may recommend additional treatment , including convalescent plasma. COVID rebound is a return of symptoms or a new positive test days after recovering from the initial illness, or after having tested negative for COVID People may experience rebound whether they received COVID antiviral treatment or not. Rebound symptoms are typically mild. Studies suggest there is no increased risk of severe COVID illness in people who experience COVID rebound after antiviral treatment. Take this screener to determine if you are at higher risk of severe COVID and may benefit from these treatments. You can use this screener even if you do not have symptoms, to be prepared in case you get sick.
