Most sore throats are caused by viral infections and clear up on their own within three to ten days. In the meantime, a combination of over-the-counter pain relievers, salt water gargles, honey, and throat lozenges can significantly reduce pain and make swallowing easier. Here’s what actually works and why.
Over-the-Counter Pain Relievers
Acetaminophen (Tylenol) and ibuprofen (Advil, Motrin) both reduce sore throat pain within hours. A review in BMJ Evidence-Based Medicine found that both provide short-term relief in under 24 hours, and there’s no strong evidence that ibuprofen works better than acetaminophen alone. Since ibuprofen carries a higher risk of stomach irritation, acetaminophen is a reasonable first choice for most people.
Ibuprofen does have one advantage: it reduces inflammation, not just pain. If your throat is visibly swollen or you’re having trouble swallowing, the anti-inflammatory effect can help. You can also alternate the two, since they work through different mechanisms and don’t interact with each other. Adults should stay under 4,000 milligrams of acetaminophen per day to avoid liver damage, and anyone who drinks three or more alcoholic beverages daily should be especially cautious with acetaminophen.
Salt Water Gargles
Gargling with warm salt water is one of the oldest sore throat remedies, and the science behind it is straightforward. When the salt concentration in the gargle is higher than the salt concentration in your throat tissue, water gets pulled out of the swollen cells through osmosis. This reduces the puffiness that makes swallowing painful.
For the most effective gargle, dissolve about two teaspoons of table salt and one teaspoon of baking soda in roughly one cup (200 ml) of warm water. The key is making the solution saltier than your body’s own fluids. Gargle for 15 to 30 seconds and spit it out. You can repeat this several times a day. The relief is temporary, usually lasting 30 minutes to an hour, but it’s safe, free, and works almost immediately.
Honey
Honey coats and soothes irritated throat tissue, and it has genuine clinical backing. A Cochrane meta-analysis covering nearly 900 children found that honey reduced cough frequency, improved quality of life, and helped both children and parents sleep better compared to no treatment. It performed about as well as the common cough suppressant dextromethorphan, which is the active ingredient in many OTC cough syrups.
A spoonful of honey on its own works, or you can stir it into warm (not boiling) tea or water. The warmth of the liquid adds its own soothing effect. One important exception: never give honey to children under one year old due to the risk of botulism.
Throat Lozenges and Sprays
Lozenges and sprays containing local anesthetics like benzocaine or lidocaine numb the throat temporarily. They work differently from each other in terms of speed and duration. Lidocaine sprays kick in faster, reaching peak numbing in about four to five minutes, but the effect wears off in roughly 14 minutes. Benzocaine lozenges take longer to start working, around 20 minutes, but the pain relief can last up to four hours.
If you need quick relief before a meal, a spray makes more sense. If you want longer-lasting comfort while you’re working or trying to sleep, a lozenge is the better pick. Even plain lozenges or hard candies help by stimulating saliva production, which keeps the throat moist and washes away irritants.
Humidity and Fluids
Dry air irritates an already inflamed throat, especially overnight when you’re breathing through your mouth. A humidifier in the bedroom can make a noticeable difference. Warm-mist and cool-mist humidifiers add the same amount of moisture to the air. By the time water vapor reaches your airways, it’s the same temperature either way. For households with children, cool-mist models are safer because there’s no risk of burns from hot water or steam.
Staying hydrated matters just as much. Warm liquids like broth, tea, or warm water with honey soothe the throat and keep mucous membranes from drying out. Cold liquids and even ice pops can also help by mildly numbing the area. The temperature you prefer is the right one. What matters most is that you’re drinking consistently throughout the day.
When a Sore Throat Needs Medical Attention
Most sore throats are viral, meaning antibiotics won’t help. Doctors use a scoring system based on five criteria to estimate the likelihood of a bacterial strep infection. Factors include fever, swollen lymph nodes in the neck, white patches on the tonsils, the absence of a cough (which points away from a cold virus), and age. A high score means a rapid strep test or throat culture is warranted, and if strep is confirmed, antibiotics shorten the illness and prevent complications.
Regardless of the cause, certain symptoms signal something more serious. The CDC recommends seeking care if you or your child experience difficulty breathing, difficulty swallowing, blood in saliva or phlegm, excessive drooling in young children, dehydration, joint swelling, or a rash. A sore throat that doesn’t improve within a few days or keeps getting worse also warrants a visit. If your sore throat lasts longer than a week, it could point to a condition that needs treatment beyond home remedies.
