COVID-19 – Treatment

Go back

When COVID-19 strikes, knowing your treatment options can make a real difference in how quickly you recover and how severe your illness becomes. From managing symptoms at home to accessing newer antiviral medications and specialized hospital care, the approach to treating this respiratory illness has evolved significantly since the pandemic began.

Understanding Your Treatment Choices: What Works Against COVID-19

The way doctors approach COVID-19 treatment depends largely on how sick you are, what other health conditions you might have, and how quickly you seek help after symptoms appear. For most people, COVID-19 causes mild to moderate illness that can be managed at home with simple remedies. However, some individuals—particularly older adults, pregnant women, those with weakened immune systems, or people with chronic conditions like heart disease, diabetes, or lung problems—face a higher risk of developing serious complications that require medical attention.[1][2]

The main goal of treatment is to help your body fight off the virus while preventing the illness from becoming severe enough to require hospitalization or intensive care. Medical experts have learned a tremendous amount since COVID-19 first emerged in late 2019. This knowledge has led to the development of several effective medications and treatment strategies that can reduce your risk of severe illness, hospitalization, and death from COVID-19.[6]

One of the most important things to understand is that timing matters greatly when it comes to treatment. Many antiviral medications work best when started within the first five to seven days after symptoms begin. This means you shouldn’t wait to contact your healthcare provider if you test positive for COVID-19 and have risk factors for severe illness, even if your symptoms seem mild at first.[9]

⚠️ Important
You don’t necessarily need a positive COVID-19 test result to start treatment if you’re at high risk for severe illness and have symptoms. If you develop symptoms like fever, cough, or shortness of breath, contact your healthcare provider immediately to discuss testing and treatment options. Treatment needs to be started within five to seven days of symptom onset to be most effective, so don’t delay seeking medical advice.[9]

Standard Treatment Approaches: Managing COVID-19 at Home and in Medical Settings

For people with mild COVID-19 symptoms who don’t have significant risk factors for severe illness, home care is usually sufficient. The foundation of at-home treatment focuses on supporting your body’s natural ability to fight the infection. This includes getting plenty of rest, which allows your immune system to work at full capacity. Your body needs extra energy to battle the virus, so don’t feel guilty about sleeping more than usual or taking frequent breaks throughout the day.[16]

Staying well-hydrated is another crucial element of home care. When you have a fever, your body loses fluids more quickly than normal. Drinking plenty of water, broth, fruit juice, or warm tea with honey helps replace these lost fluids and can soothe a scratchy throat. Aim for about eight glasses of water daily, though you might need more if you have a fever or are experiencing vomiting or diarrhea. Avoid milk, caffeinated beverages, and alcohol while you’re recovering, as these can interfere with hydration or make certain symptoms worse.[19][23]

To manage uncomfortable symptoms like fever, body aches, and headaches, over-the-counter medications can provide relief. Acetaminophen (commonly known as Tylenol) or ibuprofen (Advil, Motrin) can reduce fever and ease pain. These medications don’t fight the virus itself, but they can make you feel more comfortable while your immune system does its work. For coughs, over-the-counter cough medicines like Robitussin or Delsym may help, as can cough drops or lozenges. A teaspoon of honey can also soothe a cough, though this remedy should only be given to children over one year of age.[17][19][23]

If you’re struggling with breathing difficulties, certain positions and techniques can help. Sitting upright in a chair rather than lying flat can ease breathlessness. Leaning forward slightly and supporting yourself with your hands on your knees can also make breathing easier. Try breathing slowly through your nose and out through your mouth with your lips pursed, as if gently blowing out a candle. Opening a window for fresh air can help, but avoid using a fan directly on yourself, as this might spread viral particles to others in your home.[17]

When Medical Intervention Becomes Necessary

For people at higher risk of severe illness, medical treatments beyond basic home care become important. Healthcare providers can prescribe antiviral medications that target the virus itself, working to stop it from multiplying in your body. The most commonly used antiviral is nirmatrelvir combined with ritonavir, sold under the brand name Paxlovid. This medication comes as pills that you take by mouth at home. It’s approved for adults and children aged 12 and older who are at high risk of developing severe COVID-19.[9][10]

Another oral antiviral option is molnupiravir (marketed as Lagevrio), which is also taken at home as capsules or tablets. This medication works by interfering with the virus’s ability to copy itself. Like Paxlovid, molnupiravir must be started within five days of symptom onset to be effective. Your healthcare provider will determine which antiviral is most appropriate for you based on your specific health situation, other medications you’re taking, and how well your kidneys and liver are functioning.[9][10]

For patients who need intravenous treatment, remdesivir (brand name Veklury) is available. This antiviral is given through an IV drip at a healthcare facility for three consecutive days. It’s approved for both adults and children and can be used for people who are sick enough to need hospital care or who have risk factors for severe illness but aren’t yet hospitalized. The medication works by blocking an enzyme the virus needs to replicate.[9]

These antiviral medications can reduce your risk of hospitalization and death from COVID-19 when used appropriately. However, they may cause side effects. Paxlovid can interact with many other medications, so your doctor needs to review all the medicines you’re currently taking. Some people experience a bitter or metallic taste in their mouth while taking it. Molnupiravir may cause nausea or diarrhea in some patients. Your healthcare provider will discuss these potential side effects with you and help you weigh the benefits against any risks.[9][10]

Hospital-Based Treatments for Severe Cases

When COVID-19 becomes severe enough to require hospitalization, additional treatment options become available. Patients with serious illness may receive oxygen therapy to help them breathe more easily. In extreme cases where the lungs are severely damaged, mechanical ventilation (being placed on a breathing machine) might be necessary to keep oxygen levels adequate.[6]

For hospitalized patients with severe COVID-19, doctors may use medications that target the body’s immune response rather than the virus itself. These immunomodulators help control excessive inflammation that can damage organs. The medications work by calming down an overactive immune system that’s causing more harm than good in its attempt to fight the infection.[13]

Innovative Treatments Being Studied in Clinical Trials

While standard treatments have proven effective for many patients, researchers continue to search for even better ways to treat COVID-19. Clinical trials around the world are testing new medications and treatment approaches that might offer advantages over current options. These studies help scientists understand which treatments work best for different groups of patients and at different stages of illness.

Immunomodulatory Therapies Under Investigation

Several medications originally developed to treat autoimmune diseases are being studied for their potential to help COVID-19 patients. These drugs work by targeting specific parts of the immune system’s response to infection. Two medications that have recently been evaluated in clinical trials are abatacept and infliximab. Both are already approved for conditions like rheumatoid arthritis, but researchers wanted to see if they could help people hospitalized with moderate to severe COVID-19.[13]

These medications target different immune system pathways. The goal is to reduce harmful inflammation without completely shutting down the body’s ability to fight the virus. Clinical trials for these types of treatments typically involve hospitalized patients who are experiencing serious immune system reactions to the infection. The studies measure whether patients who receive these medications recover faster, need less oxygen support, or have better survival rates compared to those receiving standard care.[13]

Another class of medications being studied involves choosing between different immunomodulators for specific situations. For example, researchers have compared baricitinib versus tocilizumab in hospitalized adults whose COVID-19 is rapidly getting worse and who need additional immune system regulation beyond standard treatments. These comparative studies help doctors understand which medication might work better for which patients, allowing for more personalized treatment approaches.[13]

Understanding Clinical Trial Phases

When you hear about experimental COVID-19 treatments, it’s helpful to understand what phase of clinical testing they’re in. Phase I trials focus primarily on safety—researchers want to know if the treatment causes serious side effects and what dose is appropriate. These trials typically involve small numbers of participants. Phase II trials expand to more patients and begin evaluating whether the treatment actually works as intended. Researchers measure specific outcomes like symptom improvement or reduction in viral load. Phase III trials involve large groups of patients and compare the new treatment directly against existing standard treatments. These studies provide the strongest evidence about whether a new treatment is truly beneficial.[13]

Many COVID-19 treatment trials have been conducted in multiple countries, including the United States, throughout Europe, and in other regions. This international collaboration has allowed researchers to gather data more quickly and ensure that findings apply to diverse populations. Patient eligibility for these trials typically depends on factors like disease severity, age, underlying health conditions, and vaccination status.

Monoclonal Antibody Treatments

Early in the pandemic, researchers developed laboratory-made antibodies designed to attach to the virus and prevent it from entering human cells. These monoclonal antibodies were among the first targeted therapies available for COVID-19. One such treatment is sotrovimab (brand name Xevudy), which is given through an intravenous infusion. This treatment has been studied for people at highest risk of severe illness who test positive for COVID-19.[10]

However, one challenge with monoclonal antibody treatments is that they may become less effective as the virus evolves and new variants emerge. The virus can develop changes that allow it to escape recognition by these manufactured antibodies. As a result, the use of these treatments has become more limited over time, and they’re generally reserved for specific situations where they’re known to remain effective against circulating virus variants.[10]

⚠️ Important
While you’re recovering from COVID-19 at home, you need to isolate yourself from others to prevent spreading the virus. Stay in a separate room if possible and use a separate bathroom. Wear a well-fitting mask if you must be around others. Cover your coughs and sneezes with a tissue, wash your hands frequently for at least 20 seconds, and don’t share personal items like towels, cups, or eating utensils with others in your household. Clean frequently touched surfaces daily with disinfectant.[16][17]

Recognizing When to Seek Emergency Care

While most people recover from COVID-19 at home, it’s critical to know the warning signs that indicate you need immediate medical attention. Call emergency services right away if you or someone you’re caring for experiences severe trouble breathing—meaning you can’t speak a full sentence without gasping for air. Other emergency warning signs include persistent chest pain or pressure that doesn’t go away, new confusion or difficulty staying awake, and bluish discoloration of the lips or face, which indicates dangerously low oxygen levels in the blood.[17]

You should also contact your healthcare provider promptly (though not necessarily emergency services) if your symptoms are getting worse rather than better after a few days, if you’re coughing up blood, if you feel extremely weak or dizzy, or if you develop new symptoms that concern you. For people with risk factors for severe illness, it’s better to seek medical advice sooner rather than later, even if symptoms seem manageable. Early intervention with antiviral medications or other treatments can prevent mild illness from progressing to a more serious condition requiring hospitalization.[6][17]

The Role of Testing in Treatment Decisions

Getting tested for COVID-19 helps you and your healthcare provider make informed decisions about treatment. Several types of tests are available. PCR tests (polymerase chain reaction tests), also called nucleic acid amplification tests or NAATs, are highly accurate at detecting the virus. These tests involve swabbing your nose or throat and sending the sample to a laboratory for analysis. Results typically come back within a day or two.[11]

Rapid antigen tests are another option that provides results in minutes rather than days. You can often perform these tests yourself at home. While rapid tests are convenient, they may be slightly less accurate than PCR tests, particularly early in the infection when virus levels are still building up. If you have symptoms and a rapid test is negative, you might consider taking another test a day or two later or getting a PCR test to confirm the result.[11]

For people who are eligible for COVID-19 treatments because they’re at high risk of severe illness, rapid testing becomes especially important. The sooner you know you’re positive, the sooner you can start treatment. This is why healthcare providers recommend that high-risk individuals keep rapid test kits at home so they can test immediately when symptoms appear. Some pharmacies provide free rapid tests to people who qualify for COVID-19 treatment based on their medical conditions.[10]

Prevention Remains the Best Medicine

While effective treatments exist, preventing COVID-19 infection in the first place remains the best strategy for protecting your health. Staying up to date with COVID-19 vaccinations significantly reduces your risk of severe illness, hospitalization, and death, even though vaccinated people can still sometimes get infected. The vaccines train your immune system to recognize and fight the virus more effectively.[18]

Other prevention measures include practicing good hand hygiene by washing hands frequently with soap and water for at least 20 seconds, especially after being in public spaces or around others. Wearing a well-fitting mask in crowded indoor settings or when community transmission levels are high adds another layer of protection. Improving ventilation in indoor spaces by opening windows or using air filtration systems helps reduce virus concentration in the air. When you’re sick, staying home and away from others until you’ve recovered prevents spreading the illness to family members, friends, and community members.[18][20]

Understanding your personal risk factors helps you make informed decisions about precautions. People over 65, those who are pregnant, individuals with weakened immune systems, and people with chronic conditions like diabetes, heart disease, or lung disease face higher risks of severe COVID-19. If you fall into one of these categories, taking extra precautions to avoid infection makes sense, and seeking treatment quickly if you do get sick becomes even more important.[9]

FAQ

Do I need a positive test result before starting COVID-19 treatment?

No, you don’t necessarily need a positive test to start treatment if you’re at high risk for severe illness and have COVID-19 symptoms. Healthcare providers can prescribe antiviral medications based on symptoms and risk factors alone, especially since these treatments need to be started within 5 to 7 days of symptom onset. However, testing does help confirm the diagnosis and guide treatment decisions.[9]

Can I treat COVID-19 with antibiotics?

No, antibiotics don’t work against COVID-19 because it’s caused by a virus, not bacteria. Antibiotics only fight bacterial infections. However, if you develop a bacterial infection as a complication of COVID-19, such as bacterial pneumonia, your doctor might prescribe antibiotics for that secondary infection.[6]

How long do I need to isolate at home if I have COVID-19?

You should stay home and avoid contact with others while you have symptoms and feel unwell, or until you no longer have a fever without using fever-reducing medication. If you test positive, try to stay home and avoid others for at least 3 days after the test if you’re under 18, or 5 days if you’re 18 or older. Even after this period, avoid people who are at higher risk of severe illness for up to 10 days.[17]

What should I do if my COVID-19 symptoms get worse while I’m at home?

Contact your healthcare provider right away if symptoms worsen or don’t improve after several days. Seek emergency care immediately if you experience severe breathing difficulty, persistent chest pain, confusion, inability to wake up, or bluish lips or face. Don’t hesitate to call for help—early medical intervention can prevent serious complications.[17]

Are there any natural remedies that can help with COVID-19 symptoms?

While no natural remedies can cure COVID-19, some can help ease symptoms. Honey can soothe a sore throat and relieve coughs (but don’t give it to babies under 1 year old). Gargling with salt water can help sore throats. Breathing steam from a hot shower may loosen congestion. Staying well-hydrated with water, tea, and soup supports your body’s healing process. These remedies complement but don’t replace medical treatment when needed.[17][19]

🎯 Key takeaways

  • Time is critical—antiviral medications must be started within 5 to 7 days of symptom onset to work effectively, so contact your healthcare provider immediately if you test positive and have risk factors for severe illness.
  • Most people can recover from COVID-19 at home with rest, hydration, and over-the-counter medications to manage symptoms like fever and body aches.
  • Several effective antiviral medications are now available, including Paxlovid and Lagevrio (oral pills you take at home) and Veklury (intravenous treatment at a healthcare facility).
  • Your risk of severe COVID-19 is higher if you’re over 65, pregnant, have a weakened immune system, or have chronic conditions like diabetes, heart disease, or lung disease.
  • Clinical trials continue to study innovative treatments including immunomodulators and monoclonal antibodies, comparing different medications to find the best options for specific patient groups.
  • Know the emergency warning signs: severe breathing difficulty, persistent chest pain, confusion, inability to wake up, or bluish lips require immediate medical attention.
  • While treating COVID-19 at home, you must isolate yourself from others to prevent spreading the virus—stay in a separate room when possible and wear a mask around household members.
  • Prevention through vaccination, hand hygiene, masking when appropriate, and avoiding sick people remains more effective than treating illness after it occurs.
