As viruses need to infect and replicate in host cells to survive, preventing this process allows antiviral medications to combat viruses. An antiviral drug can do this in several ways:. Examples of antiviral drugs include oseltamivir Tamiflu , which tackles influenza, and acyclovir Zovirax , which treats herpes and chickenpox.
In addition to prescribing antiviral medications, doctors may recommend vaccinations. These differ from antivirals but are another safe and effective way to combat viral infections. Instead of using antiviral agents to prevent the infection process, vaccinations prepare the immune system to detect and eradicate viruses.
Wearing face coverings has been critical in preventing the spread of SARS-CoV-2 and the severity of COVID However, the effectiveness of different types of face coverings can vary greatly. Some may feature an antiviral coating to make them more effective.
A study highlights that coating masks with a glycoprotein called lactoferrin may help provide further protection and prevent the transmission of viruses. Lactoferrin mimics the sticky carbohydrates present in the throat and nasal passages, which allows it to capture viral particles in airborne droplets and stop them from infecting a person.
Another study notes that infusing masks with quaternary ammonium salts can also help protect against viral contamination by inactivating viruses. Research highlights the antiviral properties of quaternary ammonium compounds against a broad spectrum of viruses.
Several commercial cleaning products may kill harmful viruses. These products can contain various active ingredients and will usually advertise their effectiveness against viruses. Two active ingredients that household cleaning products commonly include are sodium hypochlorite and hydrogen peroxide.
These two chemicals are oxidizing agents and are capable of inactivating viruses. They do so by destroying the protein coating that protects the viral genetic material. This means that the virus can no longer reproduce. Research suggests that both of these disinfectants are effective in inactivating coronaviruses on household surfaces.
A study reported that alcohol-based hand rub solutions could inactive SARS-CoV-2, which causes COVID Several common herbs may also have antiviral properties. Their concentrated plant compounds may act to kill viruses or reduce the symptoms of the resulting diseases.
For example, oregano contains a key plant compound called carvacrol , which possesses antiviral properties that evidence suggests might be effective against SARS-CoV A study notes that compounds present in peppermint leaf extract exhibit antiviral activity against the respiratory syncytial virus.
Another study indicates that sage contains compounds that possess antiviral properties. Rosemary may also have antiviral effects.
A study highlights that a compound present in rosemary called oleanolic acid displays an antiviral response against HIV and influenza. Rosemary essential oil also shows antiviral activity against hepatitis A. Antiviral substances work to inhibit viral activity by preventing the virus from developing, replicating, and spreading.
They fit under the antimicrobial umbrella but differ from antibacterial and antifungal products. Antiviral substances include antiviral medications, which a doctor may prescribe to treat a viral infection.
They also include masks and cleaning products, which may help prevent the spread of viruses, and some herbs, which have antiviral properties. Viruses such as the novel coronavirus are highly contagious, but institutions and individuals can take many steps to limit the spread of these viruses.

Medical News Today. Health Conditions Health Products Discover Tools Connect. What to know about antiviral drugs and products. Medically reviewed by Kim Chin, RD , Nutrition — By Rachael Troughton on June 16, It is highly desirable to develop multiple antivirals whenever possible.
The development of antivirals can be challenging. Because viruses are parasites that hijack host cell machinery, care must be taken to select drug targets that interfere with viral replication while causing as little harm to healthy host cells as possible.
Like vaccines, antivirals must go through a multistep approval process by the U. Food and Drug Administration FDA. Historically, antiviral therapy has been available only for a limited number of infections, including those caused by HIV, herpes, hepatitis B and C, and influenza A and B.
Drug companies and researchers investigated new and existing antivirals for potential use in treating COVID, and some candidates have proven effective in clinical trials. Several countries have approved the use of the drug Veklury remdesivir for certain patients. For example, in October, , the U.
Food and Drug Administration FDA approved it for qualified patients who have been hospitalized as a result of COVID Veklury is administered via injection and is limited to hospital or comparable healthcare settings.
In December, , the FDA granted emergency use authorization for Paxlovid nirmatrelvir co-packaged with ritonavir and molnupiravir, orally administered drugs that can be taken at home.

The influenza-like syndrome can be prevented by paracetamol taken at the time of the injection. Psychiatric adverse effects range from irritability to a severe depressive syndrome.
Antidepressants, such as selective serotonin reuptake inhibitors, may be useful in the management. Adverse hematologic effects can occur very early during treatment. The platelet count often stabilizes rapidly, but neutropenia can deteriorate throughout treatment. In selected patients treatment with hematopoietic growth factor filgrastim may be useful.
When it applied for FDA authorization in , Pfizer presented data from a clinical trial conducted between mid-July and early December All of the trial participants were unvaccinated and they took the drug within three days of symptom onset.
The study included people who had been vaccinated or had a previous infection, which the CDC said implied the drug should be offered to people who are eligible regardless of their vaccination status.
Pfizer launched a clinical trial in March to study the safety and efficacy of Paxlovid in children and teenagers ages 6 to 17 who have COVID symptoms and test positive for the virus, and who are neither hospitalized nor at risk for severe disease.
But because many children reach 88 pounds—considered to be an adult weight—the FDA has allowed extensions of EUAs for medications such as monoclonal antibodies and remdesivir in younger age groups, adds Dr.
Topal says. The CDC says antiviral treatments work well against JN. The most common side effects of taking Paxlovid include impaired sense of taste for example, a metallic taste in the mouth and diarrhea, according to the FDA.
Most people who take Paxlovid should not experience serious side effects, explains Dr. But people should stop taking Paxlovid and call a health care provider right away if they experience any of the following signs of an allergic reaction:.
Since Paxlovid is cleared by the kidneys, dose adjustments may be required for patients with mild-to-moderate kidney disease, explains Dr. The FDA says that anyone who takes Paxlovid should contact their health provider right away if they have any signs and symptoms of liver problems: loss of appetite, yellowing of the skin and whites of the eyes jaundice , dark-colored urine, pale-colored stools and itchy skin, or stomach-area abdominal pain.
The FDA has provided a fact sheet on Paxlovid with a full list of known side effects. There is a long list of medications Paxlovid may interact with, and in some cases, doctors may not prescribe Paxlovid because these interactions may cause serious complications.
The list of drugs that Paxlovid interacts with includes some organ anti-rejection drugs that transplant patients take, as well as more common drugs like some used to treat heart arrhythmias.
Paxlovid also decreases the metabolism of anticoagulants, or blood thinners, that many older adults depend on, driving up levels of those medications in the body to a point where they are unsafe, Dr.
Topal explains. Anyone who has Human Immunodeficiency Virus 1 HIV-1 infection should talk to their health care provider before taking Paxlovid , since it may lead to some HIV-1 medicines not working as well in the future.
Paxlovid also interacts with common medications, including cholesterol-lowering statins like Lipitor. But in many cases, patients can talk to their doctors about taking a temporary break from some of those drugs while taking Paxlovid, he adds.
Pfizer had said that in the clinical trial for Paxlovid, several participants appeared to have a rebound in virus levels, although this also occurred in some people who were given a placebo.
When it approved Paxlovid in May, the FDA said there not a clear association between Paxlovid treatment and COVID rebound based on available data, and rebound rates in clinical trials were similar among participants who took Paxlovid and those who took a placebo. However, scientists are still studying the Paxlovid rebound.
The CDC says a rebound does not mean a person was resistant to Paxlovid, nor does it mean they were reinfected with the virus.
In June, the CDC released guidance for clinicians , saying a brief return of symptoms may be part of the natural history of SARS-CoV-2 infection in some people, independent of treatment with Paxlovid, adding that there is no evidence additional treatment is needed.
A CDC study reported that rebound symptoms tended to be unlikely to require hospitalization and milder than symptoms experienced during the primary infection. Not everyone diagnosed with COVID will need these treatments. They are of most benefit to people who are at the most risk of severe disease or people who are in hospital with severe disease.
Some COVID treatments can be prescribed by your doctor and taken at home. Other treatments can only be administered to patients who are in hospital. For up to date information on recommended treatments and the latest clinical guidelines visit the COVID - National Clinical Evidence Taskforce.
