A sore throat paired with a cough usually points to a viral infection, and most cases clear up on their own within a week. The good news is that several remedies, from simple kitchen ingredients to over-the-counter options, can meaningfully reduce your discomfort while your body fights off the virus. Here’s what actually works.
Honey: As Effective as OTC Cough Suppressants
Honey is one of the best-studied natural remedies for cough. A clinical trial published by the American Academy of Family Physicians found that buckwheat honey was equivalent to dextromethorphan (the active ingredient in most cough syrups) at relieving nighttime cough and improving sleep. For children aged 2 to 5, half a teaspoon was the tested dose; children 6 to 11 got one teaspoon, and those 12 to 18 got two teaspoons. Adults can use similar or slightly larger amounts.
You can take honey straight, stir it into warm water, or add it to tea. The thick, viscous texture coats the throat and calms the tickle that triggers coughing. One important rule: never give honey to a child under 12 months old due to the risk of botulism.
Warm Drinks and Staying Hydrated
Hot beverages do more than feel comforting. Research from Cardiff University’s Common Cold Centre found that a hot fruit drink provided immediate and sustained relief from runny nose, cough, sneezing, sore throat, chilliness, and tiredness, while the same drink at room temperature only helped with the runny nose and cough. The warmth itself appears to amplify the soothing effect.
Any warm liquid helps: tea, broth, warm water with lemon and honey, or heated apple juice. Staying well-hydrated also keeps your throat moist and thins mucus, making it easier to clear. Cold fluids like ice water or popsicles can temporarily numb throat pain too, so go with whatever feels best to you.
Salt Water Gargle
Dissolve half a teaspoon of table salt in one cup of warm water and gargle for 15 to 30 seconds, then spit it out. The salt draws excess fluid out of swollen throat tissue, which reduces inflammation and eases pain. You can repeat this several times a day. It won’t cure anything, but it provides noticeable short-term relief, especially first thing in the morning when throat soreness tends to peak.
Humidifiers and Moist Air
Dry indoor air irritates an already inflamed throat and can worsen a cough. The Mayo Clinic recommends keeping your home’s humidity between 30% and 50%. A cool-mist humidifier is the safest choice, especially if you have children. Steam vaporizers produce hot water that can cause burns if knocked over. If you don’t have a humidifier, sitting in a steamy bathroom for 10 to 15 minutes works as a short-term substitute.
Clean your humidifier regularly. Standing water breeds mold and bacteria, which can make respiratory symptoms worse instead of better.
Over-the-Counter Medications
When home remedies aren’t enough, a few categories of OTC medicine target specific symptoms:
- Pain relievers: Ibuprofen and acetaminophen reduce throat pain and bring down a fever. Either one works well for sore throat discomfort.
- Cough suppressants: Products containing dextromethorphan quiet a dry, hacking cough by reducing the urge to cough.
- Expectorants: Guaifenesin loosens thick mucus in your airways so you can cough it up more easily. This is the better choice when your cough feels “wet” or productive.
One caution: many combination cold medicines contain overlapping active ingredients, including pain relievers. If you’re already taking ibuprofen or acetaminophen separately, check the label on any multi-symptom product to avoid doubling up and taking a dangerous dose.
Zinc Lozenges
Zinc lozenges can shorten the overall duration of a cold by roughly a third when taken within the first day or two of symptoms. A meta-analysis of randomized trials found that zinc lozenges providing more than 75 mg of elemental zinc per day reduced cold duration by about 33% to 37%, with similar benefits for nasal symptoms, sore throat, and cough. Look for zinc acetate or zinc gluconate lozenges and start them as early as possible for the best effect. Some people experience nausea or a metallic taste, which usually resolves after stopping.
Mucilage-Containing Herbs
Marshmallow root and slippery elm both contain a gel-like substance called mucilage that coats and lubricates the throat when swallowed. This creates a temporary protective layer over irritated tissue, which can reduce the scratchy sensation that provokes coughing. You’ll find both ingredients in throat-coat teas and herbal lozenges at most pharmacies and grocery stores. They won’t speed up recovery, but they provide a pleasant, drug-free way to manage discomfort throughout the day.
When a Sore Throat Signals Something Else
The combination of sore throat and cough together is actually a reassuring sign in one respect: it strongly suggests a viral cause rather than strep throat. According to the CDC, patients with strep typically do not have a cough, runny nose, or hoarseness. Strep throat tends to come on suddenly with fever, pain when swallowing, and visibly red or swollen tonsils, sometimes with white patches.
That said, a few patterns warrant a call to your doctor. A sore throat lasting longer than a week, a fever above 101°F that persists for several days, difficulty swallowing or breathing, blood in your saliva, or a visibly swollen neck all suggest something beyond a routine virus. For infants under 3 months, any fever of 100.4°F or higher needs prompt medical attention.
Most sore throat and cough episodes peak around days two through four and resolve within seven to ten days. If your symptoms are steadily improving, even slowly, that’s a good sign your body is handling it on its own.
