Most upper respiratory infections are caused by viruses, which means antibiotics won’t help. The good news is that the right combination of over-the-counter remedies can meaningfully reduce your symptoms while your body fights the infection off. A typical URI lasts one to two weeks, and your main job during that time is managing pain, congestion, and cough so you can rest and recover.
Why Antibiotics Usually Aren’t the Answer
The common cold, flu, COVID-19, most sore throats, and acute bronchitis are all viral infections. Antibiotics only work against bacteria, so taking them for a viral URI won’t speed your recovery and can cause side effects like diarrhea and yeast infections. The CDC lists very few respiratory conditions that actually warrant antibiotics: strep throat, pneumonia, and some sinus infections that have lasted long enough to suggest a bacterial cause. If your doctor doesn’t prescribe antibiotics, it’s not because they’re dismissing your symptoms. It’s because the medication genuinely wouldn’t help.
Antiviral medications do exist for specific infections like the flu and COVID-19, but they need to be started early and require a prescription. For the vast majority of URIs, symptom management is the primary treatment.
Pain Relief and Fever Reducers
Acetaminophen (Tylenol) and ibuprofen (Advil, Motrin) are the two main options for the headaches, body aches, sore throat, and low-grade fevers that come with a URI. Acetaminophen reduces pain and fever. Ibuprofen does the same but also reduces inflammation, which can be especially helpful for a raw, swollen throat. Either one works well, and some people alternate between the two for around-the-clock relief.
The key safety rule with acetaminophen is to stay under 4,000 milligrams in 24 hours. That limit is easier to exceed than you’d think, because acetaminophen is an ingredient in many multi-symptom cold products. Check the label of every OTC product you’re taking to make sure you’re not doubling up. If you have high blood pressure, be aware that ibuprofen and other NSAIDs can raise blood pressure, so acetaminophen is generally the safer choice.
Choosing the Right Decongestant
A stuffed nose is one of the most miserable parts of a URI, and the decongestant aisle can be confusing. Here’s what you need to know: the FDA has proposed removing oral phenylephrine from the market after an advisory committee unanimously concluded it doesn’t actually work as a nasal decongestant at recommended doses. Phenylephrine is the active ingredient in many popular cold products sitting on open shelves right now, including certain versions of Sudafed PE, Dayquil, and others. Check the label.
Pseudoephedrine, on the other hand, is effective. You’ll need to ask for it at the pharmacy counter (it’s kept behind the counter in most states, though no prescription is required). It works by narrowing blood vessels in the nasal passages, which reduces swelling and lets you breathe. The trade-off is that it narrows blood vessels elsewhere too. If you have high blood pressure, particularly if it’s severe or poorly controlled, decongestants like pseudoephedrine are not safe for you.
Nasal spray decongestants containing oxymetazoline (Afrin) provide fast, targeted relief, but you should not use them for more than three consecutive days. Longer use can cause rebound congestion that’s worse than what you started with.
Cough and Chest Congestion Relief
Two ingredients handle cough and congestion in different ways, and picking the right one depends on what kind of cough you have.
- Dextromethorphan (DM) is a cough suppressant. It works on the brain’s cough center to quiet the reflex. It’s most useful for a dry, hacking cough that keeps you awake or makes your throat raw.
- Guaifenesin is an expectorant. It thins and loosens mucus in your airways, making a productive (wet) cough more effective at clearing congestion. If your chest feels tight and full, this is the one to reach for.
Many products combine both ingredients for people dealing with a mixed cough. When you’re coughing up mucus, suppressing the cough entirely isn’t ideal because coughing is how your body clears the infection from your lungs. In that case, guaifenesin alone, along with plenty of fluids, is the better strategy.
Zinc Lozenges: Timing Matters
Zinc is one of the few supplements with solid evidence behind it for colds. A meta-analysis of seven trials found that zinc lozenges reduced cold duration by about 33%, which can mean shaving three or four days off a 10-day illness. But there are important details that determine whether zinc actually works for you.
First, you need to start within the first 24 hours of symptoms. Second, the dose matters: roughly 80 milligrams of elemental zinc per day, split across six to nine lozenges throughout the day, for one to two weeks. Both zinc acetate and zinc gluconate forms work equally well. Doses above 100 mg per day don’t appear to provide extra benefit.
Watch out for lozenges that contain citric acid or tartaric acid, which bind to zinc ions and prevent them from being released. These formulations look the same on the shelf but won’t deliver free zinc where it’s needed. Check the inactive ingredients list and avoid those additives.
Saline Nasal Rinses
Rinsing your nasal passages with salt water is one of the simplest and cheapest things you can do. A well-designed study of 390 children with URIs found that those using daily saline irrigation had significantly less nasal congestion, fewer secretions, and used less medication than those receiving routine care alone. The benefits extended beyond the acute illness, with fewer subsequent episodes in the weeks that followed.
You can use a neti pot, squeeze bottle, or saline spray. Lean over a sink, tilt your head slightly, and pour or squeeze the solution into one nostril. It flows through and drains from the other side, flushing out mucus and viral particles. Use lukewarm water that’s been boiled and cooled, distilled, or filtered. Never use tap water straight from the faucet, as it can contain organisms that are dangerous when introduced into the nasal passages. Clean your device after every use.
What to Skip if You Have High Blood Pressure
If you’re managing hypertension, the cold medicine aisle requires extra caution. Decongestants (pseudoephedrine, phenylephrine, oxymetazoline) narrow blood vessels throughout the body, which raises blood pressure. NSAIDs like ibuprofen and naproxen can do the same. For pain and fever, stick with acetaminophen. For congestion, saline rinses and steam inhalation are your safest options. If you need more relief, talk to your pharmacist about what’s compatible with your blood pressure medications.
Cold Medicine and Children
OTC cough and cold medications carry real risks for young children. The FDA recommends against giving these products to children under 2, and manufacturers voluntarily label them “do not use in children under 4.” Children in this age group who have taken these products have experienced seizures, allergic reactions, difficulty breathing, and dangerous drops in blood sugar and potassium. For young children with a URI, saline drops, a cool-mist humidifier, fluids, and acetaminophen or ibuprofen (at age-appropriate doses) for fever and pain are the safest approach.
When a URI Needs Medical Attention
Most URIs resolve on their own within two weeks. Contact a healthcare provider if your symptoms are severe, last longer than two weeks, or keep coming back. Head to the emergency room for a fever above 103°F, difficulty breathing, chest pain, wheezing, confusion, or skin pulling inward between the ribs with each breath. These signs suggest the infection may have moved deeper into the lungs or that something other than a simple URI is going on.
