If you’ve tested positive for COVID-19, the most effective treatment is the prescription antiviral Paxlovid, taken within five days of your first symptoms. For most people managing mild illness at home, though, the plan combines over-the-counter medications for symptom relief, steady hydration, and rest. What you take depends on your risk level, how far along your symptoms are, and what you’re already taking for other conditions.
Paxlovid: The Main Prescription Option
Paxlovid is the primary antiviral used for outpatient COVID treatment. It’s approved for adults and authorized for anyone 12 and older who weighs at least 88 pounds. The course is twice daily for five days, started as soon as possible and within five days of symptom onset. You don’t need any special testing before starting it, just a positive COVID test and a prescription.
Paxlovid works best for people at higher risk of severe illness: older adults, those with chronic conditions like diabetes or heart disease, and immunocompromised individuals. If you’re young, healthy, and vaccinated, your doctor may decide you don’t need it. But if you do qualify, timing matters. The sooner you start, the more effective it is at keeping you out of the hospital.
One important caveat: Paxlovid interacts with a long list of other medications. It affects how your body processes certain drugs, which can either reduce Paxlovid’s effectiveness or cause dangerous spikes in other medications. Specific drugs to watch out for include certain sedatives (midazolam, triazolam), the mood stabilizer carbamazepine, and the antipsychotic lurasidone. Blood thinners, some heart medications, and certain cholesterol drugs can also interact. Before you fill the prescription, make sure your doctor or pharmacist reviews everything you’re currently taking, including supplements.
Over-the-Counter Medications for Symptom Relief
Most people with COVID will manage their symptoms at home with the same medications used for a bad cold or flu. Here’s what helps and when to use it.
For fever and body aches: Acetaminophen (Tylenol) is the preferred first choice. It has a better safety profile than ibuprofen when it comes to heart, stomach, and kidney side effects. That said, there’s no clinical evidence that ibuprofen (Advil, Motrin) is actually harmful during COVID, despite early pandemic concerns. If acetaminophen isn’t controlling your fever, ibuprofen is a reasonable alternative.
For cough: Dextromethorphan, the active ingredient in many cough suppressants (Delsym, Robitussin DM), is the standard option. COVID cough can linger for weeks, and while no cough medicine will eliminate it entirely, dextromethorphan can take the edge off. For a wet, productive cough, guaifenesin (Mucinex) helps thin mucus so it’s easier to clear.
For congestion and sore throat: Nasal decongestants containing pseudoephedrine or phenylephrine can help with stuffiness. Throat lozenges, warm salt water gargles, and honey in tea all provide real relief for sore throat pain. Antihistamines like diphenhydramine or loratadine can help if post-nasal drip is driving your cough or congestion.
All of these medications have been used safely for decades for cold and flu symptoms. While none have been tested in large COVID-specific clinical trials, the symptom mechanisms are similar enough that regulatory agencies consider them appropriate for COVID symptom management.
Hydration and Electrolytes
Fever, sweating, and reduced appetite can dehydrate you faster than you realize. Aim for at least 64 to 70 ounces of water daily while you’re sick. If you’re running a fever or sweating heavily, you’re losing electrolytes too. A simple approach is mixing water with an electrolyte sports drink in a roughly half-and-half ratio, or using electrolyte powder packets.
Avoid alcohol and caffeinated drinks, both of which pull water out of your system. Broth-based soups pull double duty by providing both fluids and sodium.
What About Vitamin D, Zinc, and Other Supplements?
Vitamin D and zinc were among the most widely discussed supplements early in the pandemic, but clinical trials have been disappointing. A double-blind, placebo-controlled trial of 181 COVID patients found that neither vitamin D supplementation nor zinc (40 mg daily) had any effect on the time it took to recover from fever, cough, or shortness of breath. They also didn’t shorten hospital stays or reduce the need for ventilation. Median time to symptom resolution was three days in both the supplement and placebo groups.
Vitamin C and quercetin (a plant compound found in onions, berries, and green tea) have shown some theoretical promise in lab studies. Vitamin C supports immune function, and quercetin appears to interfere with viral replication in cell cultures. Some researchers have proposed them as a combination therapy. But “promising in a lab” is a long way from “proven in people,” and there isn’t strong clinical trial evidence showing they speed recovery from an active COVID infection.
None of these supplements are harmful at normal doses, and if you’re already taking them as part of your routine, there’s no reason to stop. But don’t expect them to meaningfully change the course of your illness once you’re already symptomatic.
Signs You Need More Than Home Treatment
Most COVID cases resolve at home within one to two weeks. But certain warning signs mean your body needs more help than over-the-counter treatments can provide. The most important number to watch is your blood oxygen level. Oxygen saturation below 92% is associated with increased complications, and readings below 90% are linked to significantly worse outcomes. A pulse oximeter, available at most pharmacies for under $30, lets you track this at home.
Beyond oxygen levels, watch for difficulty breathing at rest, persistent chest pain or pressure, confusion or difficulty staying awake, and an inability to keep fluids down. A sudden worsening after you seemed to be improving, typically around days 7 to 10, can signal that your immune response is causing problems rather than the virus itself. Any of these patterns warrant urgent medical attention.
Putting It All Together
- Day 1 to 2 of symptoms: Test for COVID. If positive and you’re at higher risk, contact your doctor about Paxlovid immediately. The five-day window starts closing fast.
- Throughout your illness: Use acetaminophen for fever and pain, dextromethorphan or guaifenesin for cough, and decongestants for stuffiness. Stay on top of hydration with water and electrolytes.
- Monitor yourself: Check your oxygen saturation a few times a day if you have a pulse oximeter. Note whether symptoms are gradually improving or suddenly worsening.
- Skip the supplement panic-buy: Vitamin D, zinc, and vitamin C haven’t shown meaningful benefits for active infection in clinical trials. Focus your energy on rest, fluids, and proven symptom relief.
