Most people with COVID-19 recover at home with rest, fluids, and over-the-counter medications. For those at higher risk of severe illness, prescription antivirals like Paxlovid can reduce the chance of hospitalization by a wide margin, but they need to be started within the first few days of symptoms. How you treat COVID depends on your risk level, how far along your symptoms are, and how severe they become.
Managing Mild COVID at Home
If you’re generally healthy and your symptoms feel like a bad cold or flu, home care is the main treatment. Acetaminophen or ibuprofen will bring down a fever and ease body aches. Stay well-hydrated, especially if you’re dealing with diarrhea or vomiting, which can quietly push you toward dehydration. Water, broth, and electrolyte drinks all work. There’s no specific volume you need to hit, but if your urine is dark, you need more fluids.
Rest matters more than people tend to give it credit for. COVID fatigue can linger if you push through the acute phase. Sleep as much as your body asks for in the first week, and don’t rush back to exercise or heavy activity just because your fever breaks. Most mild cases resolve within one to two weeks, though a lingering cough or tiredness can stretch beyond that.
When Prescription Antivirals Are Worth Pursuing
Prescription antivirals are recommended for people at higher risk of ending up in the hospital. This includes adults over 65, people with obesity, diabetes, heart disease, chronic lung conditions, weakened immune systems, or other conditions the CDC lists as risk factors. If you fall into any of these categories, contact a doctor as soon as you test positive. Timing is critical.
The preferred treatment is Paxlovid (nirmatrelvir/ritonavir), a five-day oral course approved for adults and for adolescents over 12 who weigh at least 88 pounds. It works by blocking the virus’s ability to replicate, and it’s most effective when started within five days of your first symptoms. The sooner you begin, the better.
If Paxlovid isn’t an option, intravenous remdesivir is the next choice. It requires three days of infusions, started within seven days of symptom onset. In clinical trials of unvaccinated, high-risk outpatients, it reduced the risk of hospitalization and death by 87%. You’ll need to visit an infusion center or clinic for each dose, which makes it less convenient than a pill but still highly effective.
If neither Paxlovid nor remdesivir is available or appropriate, molnupiravir is the backup. It’s also a five-day oral course: four capsules taken every 12 hours. It’s less effective than the other two options, which is why it sits in the third-line position.
Paxlovid and Drug Interactions
One of the biggest practical hurdles with Paxlovid is that it interacts with a long list of common medications. It contains ritonavir, which changes how your liver processes many drugs, temporarily raising or lowering their levels in your blood. Some of these interactions are dangerous enough that certain medications are completely off-limits during the five-day course.
The contraindicated list includes several heart rhythm drugs, certain cholesterol medications (lovastatin, simvastatin), specific anti-seizure drugs (carbamazepine, phenytoin), the antibiotic rifampin, and the herbal supplement St. John’s Wort. Blood thinners like warfarin and rivaroxaban may need dose adjustments. So can immunosuppressants like tacrolimus and cyclosporine, some blood pressure medications, and several psychiatric drugs including quetiapine and clozapine.
This doesn’t mean you can’t take Paxlovid if you’re on other medications. It means your prescriber needs a complete list of everything you take, including supplements, so they can decide what to pause, adjust, or monitor. Some medications can safely be held for those five days.
Monitoring Oxygen Levels at Home
A pulse oximeter is one of the most useful tools you can have during a COVID infection, particularly if you’re over 60 or have lung or heart conditions. It clips onto your fingertip and reads your blood oxygen saturation in seconds.
Normal readings sit between 95% and 100%. If your level drops below 90%, get emergency medical help immediately. That threshold signals your lungs aren’t transferring enough oxygen into your blood, and it can happen even before you feel severely short of breath. Some people with COVID experience what’s called “silent hypoxia,” where oxygen drops without the expected gasping sensation. Check your levels a few times a day, especially if you notice increasing breathlessness, chest tightness, or confusion.
What Happens in the Hospital
Hospital treatment for COVID looks very different from home care because it targets the inflammatory response that can spiral out of control in severe cases. The key medication is dexamethasone, a corticosteroid that dials down the immune system’s overreaction. It’s recommended for every hospitalized patient who needs supplemental oxygen, and it becomes even more important for those on high-flow oxygen or ventilators. Notably, dexamethasone is not recommended for patients who don’t need oxygen support, because suppressing the immune response too early can actually slow viral clearance.
For patients whose oxygen needs are climbing quickly and whose blood markers show surging inflammation, doctors add a second layer of immune-calming treatment. Tocilizumab, given as an IV infusion, blocks a specific inflammatory signal that drives the most dangerous phase of severe COVID. It’s used alongside dexamethasone, not instead of it. Remdesivir may also be given in the hospital setting, often paired with the steroid for patients on conventional oxygen.
COVID Rebound After Treatment
Some people feel better after finishing antivirals, then see symptoms return a few days later. This is called COVID rebound, and it got a lot of attention when Paxlovid first became widely used. The reality is more nuanced than the early headlines suggested. A large observational study found rebound occurred in about 6.6% of people who took Paxlovid, 4.8% of those who took molnupiravir, and 4.5% of people who received no antiviral treatment at all. The rates were statistically similar across all three groups.
Some smaller studies have reported higher rebound rates of 10% to 14% among treated patients, but the overall picture is that rebound is not unique to antiviral use. It appears to be a feature of how some people’s immune systems interact with the virus. Rebound episodes are typically mild and short-lived. NIH guidelines are clear that the possibility of rebound should not discourage anyone from taking antivirals when they’re indicated, because the benefit in preventing severe illness far outweighs the inconvenience of a few extra days of symptoms.
Signs That Need Urgent Attention
Most COVID infections stay mild, but certain warning signs mean you should seek care right away. Persistent chest pain or pressure, new confusion or difficulty staying awake, an inability to keep fluids down, and lips or nail beds turning bluish all warrant an emergency visit. The oxygen threshold of 90% applies here too. If you’re watching your numbers trend downward over hours, even if they haven’t hit 90% yet, that trajectory itself is worth a call to your doctor or a trip to urgent care.
