Most COVID-19 cases can be managed at home with over-the-counter medications, rest, and fluids. The key decision is whether you also need a prescription antiviral, which must be started within five days of your first symptoms to work. That narrow window means acting quickly matters more than anything else.
Managing Fever, Pain, and Cough at Home
Acetaminophen (Tylenol) and ibuprofen (Advil, Motrin) both reduce fever and relieve the body aches, headaches, and sore throat that come with COVID. You can alternate between the two if one alone isn’t enough. For cough, an over-the-counter cough suppressant containing dextromethorphan can take the edge off, and throat lozenges or warm liquids help with soreness.
Saline nasal rinses are a simple, low-risk way to ease congestion. Rinsing twice a day with normal saline using a squeeze bottle or neti pot helps clear mucus and may reduce the amount of virus sitting in your nasal passages. You can buy saline rinse kits at any pharmacy without a prescription. Just use distilled or previously boiled water to mix the solution.
Honey (a teaspoon at a time, swallowed or stirred into warm tea) has modest evidence behind it for soothing coughs in adults and children over one year old. It won’t shorten your illness, but it can make nighttime coughing more tolerable.
Staying Hydrated When You Feel Awful
Fever, sweating, and reduced appetite all pull fluid and salt from your body. Water alone isn’t always enough to replace what you’re losing. Broth-based soups are surprisingly effective: a liter of condensed chicken soup contains about 160 milliequivalents of sodium, roughly the same as a liter of IV saline. A single chicken bouillon cube dissolved in hot water delivers about 84 milliequivalents. Sports drinks, by comparison, often don’t contain enough sodium to fully rehydrate you during an illness with heavy fluid loss.
Aim to drink enough that your urine stays pale yellow. If you’re vomiting or have diarrhea, small frequent sips of broth or an oral rehydration solution work better than trying to drink large amounts at once.
Who Should Get Prescription Antivirals
Antiviral treatment is recommended if you’re 50 or older, or if you have an underlying condition that raises your risk of severe illness. The list of qualifying conditions is long and includes diabetes (type 1 or 2), heart disease, chronic kidney disease, chronic lung conditions like asthma or COPD, obesity (BMI of 25 or higher), cancer, HIV, immunosuppression from medications or transplant, pregnancy, liver disease, and a history of stroke. Current or former smokers also qualify, as do people with certain disabilities or mental health conditions like depression.
If any of those apply to you, contact your doctor or a telehealth provider as soon as you test positive. The most commonly prescribed oral antiviral must be started within five days of symptom onset. An IV antiviral option has a slightly wider window of seven days. Waiting until day four or five to “see how you feel” can mean missing the treatment window entirely.
The oral antiviral works by blocking the virus from replicating, and it’s available for adults and adolescents 12 and older who weigh at least 88 pounds. One important caveat: it interacts with a wide range of common medications because it affects how your liver processes drugs. Blood thinners, certain cholesterol medications, some blood pressure drugs, migraine medications, and many others can be affected. Your prescriber will need to review everything you’re taking. In some cases, a medication can be temporarily paused; in others, a different antiviral may be a better fit.
The Treatment Timing Window
This is the single most important thing to understand about COVID treatment: antivirals only work when started early. The CDC emphasizes that treatment must begin within five to seven days of your first symptoms, depending on which medication is used. Data consistently shows that the earlier you start, the more effective these drugs are at preventing hospitalization and death.
Don’t wait for symptoms to get worse before seeking treatment. If you’re in a high-risk group, test as soon as you notice symptoms and call your provider the same day you get a positive result. Many pharmacies and telehealth platforms can now prescribe antivirals quickly, sometimes the same day.
Reducing Your Risk of Long COVID
A clinical trial published in The Lancet Infectious Diseases found that metformin, a widely used diabetes medication, reduced the incidence of long COVID by about 41% when taken during acute infection. Among participants who started it within three days of symptom onset, the reduction was even more dramatic, with a 63% lower risk compared to placebo. The study enrolled adults aged 30 to 85 who were overweight or obese. Notably, neither ivermectin nor fluvoxamine showed any effect on long COVID risk in the same trial.
Metformin is not currently a standard part of COVID treatment guidelines, but some clinicians are prescribing it off-label for high-risk patients who want to lower their chances of lingering symptoms. This is worth discussing with your provider early in your illness if long COVID is a concern for you.
Warning Signs That Need Emergency Care
Most people recover at home without complications, but certain symptoms signal that your body is struggling in ways that require immediate medical attention:
- Trouble breathing or feeling short of breath at rest
- Persistent chest pain or pressure
- New confusion or difficulty thinking clearly
- Inability to stay awake or difficulty being roused from sleep
- Color changes in lips, nail beds, or skin appearing pale, gray, or blue
If you or someone you’re caring for develops any of these, call 911. Let the dispatcher know you’re dealing with a suspected or confirmed COVID case so the responding team can prepare.
A Practical Timeline for Your Illness
Day one of symptoms is when the clock starts. Test immediately with a rapid antigen test. If it’s positive and you have any risk factors, contact your provider that day to discuss antivirals. While you’re waiting, start managing symptoms with acetaminophen or ibuprofen, push fluids (especially broths and soups), and rest.
Most people feel worst between days two and five. Fever, fatigue, and body aches typically peak during this stretch. Keep managing symptoms and stay hydrated. Monitor your breathing and energy level. If you have a pulse oximeter, oxygen readings below 95% are worth reporting to your doctor; below 92% warrants urgent evaluation.
By days seven through ten, the majority of people with mild to moderate illness are turning the corner. Fatigue and cough can linger for weeks, but active fever and severe aches usually resolve. If you’re still getting worse after day seven rather than improving, that’s a reason to check in with a healthcare provider even if you don’t have emergency warning signs.
