No medicine cures a cold, but several over-the-counter options can make the week or so of symptoms more bearable. The key is matching the right product to your specific symptoms, because cold medicines work best when you treat what’s actually bothering you rather than grabbing a multi-symptom combo off the shelf.
Most colds peak within two to three days and clear up in under a week. The goal of any medication during that window is comfort, not cure.
Pain Relievers for Fever, Sore Throat, and Body Aches
Acetaminophen (Tylenol) and ibuprofen (Advil, Motrin) are the two go-to options for the achiness, sore throat, and low-grade fever that often come with a cold. Both work about equally well. A large review graded at the highest level of clinical evidence found no meaningful difference between the two for pain, fever, or severe symptoms. Taking them on a fixed schedule didn’t improve results over taking them only when you felt bad, either.
Pick whichever one you tolerate best. If you have high blood pressure, acetaminophen is the safer choice. Ibuprofen and other anti-inflammatory painkillers (naproxen, aspirin) can raise blood pressure, so people with hypertension should avoid them for cold symptom relief.
Decongestants: What Still Works
Stuffy nose is one of the most disruptive cold symptoms, and this is where the medicine aisle has gotten confusing. Many popular oral cold tablets contain phenylephrine as their decongestant. The FDA has proposed removing oral phenylephrine from the market after an advisory committee unanimously concluded it does not work at the recommended dose. The decision is based on effectiveness, not safety, and the ingredient is still being sold while the proposal moves through regulatory steps. But if you’re buying a decongestant today, oral phenylephrine is not a good use of your money.
Pseudoephedrine (the active ingredient in original Sudafed) remains effective. It’s kept behind the pharmacy counter in the U.S. and requires an ID to purchase, but no prescription. It genuinely shrinks swollen nasal passages and can make breathing noticeably easier within 30 minutes.
Nasal spray decongestants containing oxymetazoline (Afrin) work faster and more directly than pills. The tradeoff is that using them for more than three consecutive days can cause rebound congestion, where your nose gets stuffier than before once you stop. Keep spray use short.
If You Have High Blood Pressure
All decongestants narrow blood vessels, which is exactly how they reduce nasal swelling. That same mechanism raises blood pressure throughout the body. If your blood pressure is severe or not well controlled, skip decongestants entirely. Saline nasal spray is a safe alternative that physically rinses mucus from nasal passages without affecting blood pressure. Also check cold medicine labels for sodium content, since excess salt can compound the problem.
Cough Medicines: Limited Evidence
Cough suppressants and expectorants are among the most commonly purchased cold medicines, but the evidence behind them is surprisingly thin. Dextromethorphan (the “DM” in many cough syrups) is the most widely used cough suppressant. In clinical comparisons, it performed no better than no treatment at all for nighttime cough in children with upper respiratory infections.
Guaifenesin, the mucus-thinning ingredient in products like Mucinex, has similarly mixed results. Some studies show a small reduction in cough symptoms, while others show none. A major clinical guideline from the UK’s National Institute for Health and Care Excellence concluded that the benefit of mucolytics is clinically unclear and recommended against offering them for acute cough.
This doesn’t mean these products never help anyone. Some people feel meaningful relief, and a week-long cold can feel long enough that even placebo-level comfort has value. Just know that the science doesn’t strongly support either product, so if one doesn’t seem to be doing anything for you, there’s no reason to keep taking it.
Honey for Cough
Honey has more clinical support for cough than many pharmacy products. In a study comparing honey, dextromethorphan, and no treatment in children with upper respiratory infections, honey reduced cough frequency and overall symptom scores better than no treatment. Dextromethorphan didn’t outperform either honey or no treatment on any measured outcome.
A spoonful of honey before bed coats the throat and seems to calm the cough reflex enough to improve sleep. It’s a reasonable first option for adults and children over age one. (Honey should never be given to infants under 12 months due to botulism risk.)
Zinc: Modest but Real Benefit
Zinc lozenges are the one supplement with credible evidence for shortening a cold. A Cochrane review of eight treatment studies found that zinc may reduce the duration of cold symptoms by roughly two days compared to placebo, cutting an average week-long illness down to about five days. The evidence was rated low-certainty because the studies used different zinc formulations, doses, and delivery methods (lozenges versus nasal sprays), making it hard to pinpoint the ideal product.
If you want to try zinc, start it early. The studies showing benefit generally had people begin taking it within 24 hours of the first symptom. Lozenges dissolved in the mouth appear to be the most studied form. Zinc nasal sprays have been linked to long-lasting loss of smell in some cases and are best avoided.
Cold Medicine and Children
The rules are different for kids. The FDA does not recommend any over-the-counter cough and cold medicines for children younger than two, citing the risk of serious and potentially life-threatening side effects. Manufacturers have voluntarily extended that warning to children under four on product labels. The FDA also specifically warns against homeopathic cough and cold products for children under four, stating it is not aware of any proven benefits.
For young children with colds, saline nose drops, a cool-mist humidifier, plenty of fluids, and honey (for those over age one) are the practical tools. Acetaminophen or ibuprofen can be used for fever and discomfort at age-appropriate doses.
What a Normal Cold Looks Like
Symptoms typically peak around day two or three and resolve in under a week. A mild cough can linger a bit longer. Knowing this timeline helps you judge whether medicine is working or whether something else might be going on.
Colds sometimes trigger secondary infections. Middle ear infections and sinus infections are the most common, usually showing up as new pain or pressure after initial symptoms had started improving. More serious complications include asthma flare-ups, bronchitis, and pneumonia. A fever that returns after going away, symptoms that suddenly worsen after several days of improvement, or difficulty breathing all suggest something beyond a simple cold.
