Ibuprofen is the single most effective over-the-counter medicine for a sore throat. In clinical trials comparing it head-to-head with acetaminophen (Tylenol), 400 mg of ibuprofen reduced throat pain by 80% at three hours, while 1,000 mg of acetaminophen reduced it by only 50%. At six hours, ibuprofen still provided 70% relief compared to just 20% for acetaminophen. The reason: ibuprofen fights both pain and the inflammation causing it, while acetaminophen only blocks pain signals.
That said, the “best” medicine depends on what’s causing your sore throat, how severe it is, and whether you’re treating an adult or a child. Here’s what works, when, and why.
Ibuprofen vs. Acetaminophen
Both ibuprofen and acetaminophen are safe, widely available choices. But across five randomized controlled trials involving nearly 700 adults and children with pharyngitis, ibuprofen consistently outperformed acetaminophen for both the depth and duration of pain relief. The standard effective dose is 400 mg taken three times a day for adults, or 10 mg per kilogram of body weight for children.
Acetaminophen still has a role. If you can’t take ibuprofen because of stomach issues, kidney problems, or because you’re on blood thinners, acetaminophen at 1,000 mg (for adults) three times a day will take the edge off. It just won’t last as long or reduce the swelling in your throat the way ibuprofen does.
You can also alternate the two, taking ibuprofen and then acetaminophen a few hours later. This keeps a more steady level of relief throughout the day without exceeding the safe dose of either one.
Throat Lozenges and Sprays
Topical treatments numb the throat directly, which makes them a good add-on when swallowing is particularly painful. Benzocaine lozenges provide noticeable relief within about 20 minutes. Because benzocaine doesn’t dissolve easily, it stays on the tissue longer than you might expect. Lidocaine throat sprays work faster, reaching peak numbing in about four to five minutes, but the effect wears off more quickly.
These products treat pain only. They don’t reduce inflammation or fight infection. Think of them as a bridge for the worst moments, like right before eating, while your oral pain reliever handles the background work.
Salt Water and Honey
A salt water gargle is one of the simplest remedies that actually holds up. Mix a quarter to half teaspoon of table salt into eight ounces of warm water and gargle for 15 to 30 seconds. The salt draws excess fluid out of swollen throat tissue, temporarily reducing the puffiness that makes swallowing hurt. You can repeat this several times a day.
Honey coats and soothes irritated tissue and has mild antimicrobial properties. It’s particularly useful for sore throats accompanied by a cough. A spoonful straight, or stirred into warm tea, can provide real relief. One important exception: never give honey to a child under one year old due to the risk of infant botulism.
When Postnasal Drip Is the Cause
Not every sore throat starts in the throat. Postnasal drip, where mucus from your nose or sinuses constantly drains down the back of your throat, is one of the most common causes of a persistent, scratchy sore throat. If your throat feels worse in the morning or you’re constantly clearing mucus, drainage is likely the culprit.
In that case, the best medicine targets the drip, not the throat itself. For allergies, a non-drowsy antihistamine like loratadine (Claritin), cetirizine (Zyrtec), or fexofenadine (Allegra) can dry up the source. If congestion from a cold is driving the drainage, an oral decongestant like pseudoephedrine (Sudafed) helps shrink swollen nasal passages. Nasal decongestant sprays work fast but should only be used for a day or two, since longer use can make congestion rebound and worsen.
When You Need Antibiotics
Most sore throats are viral and will resolve on their own within about a week. Antibiotics do nothing for viral infections. They’re only appropriate for bacterial infections, specifically group A strep (strep throat), which requires a positive rapid test or throat culture to confirm.
If you do test positive, the first-line treatment is penicillin or amoxicillin taken for a full 10-day course. Once you start antibiotics for strep, symptoms typically improve within two to three days. Finishing the entire course matters even after you feel better, because stopping early can allow the bacteria to survive and cause complications.
You can’t reliably tell the difference between viral and bacterial pharyngitis just by looking at your throat. A sore throat with a cough, runny nose, and hoarseness is almost certainly viral. A sore throat with fever, swollen lymph nodes, white patches on the tonsils, and no cough is more suspicious for strep, but testing is the only way to know for sure.
Corticosteroids for Severe Pain
For sore throats severe enough to send you to urgent care or the emergency department, a single dose of an oral corticosteroid can speed up pain relief significantly. A clinical practice guideline published in The BMJ supports this approach for both adults and children aged five and older, regardless of whether the sore throat is viral or bacterial. The steroid rapidly reduces inflammation in the throat tissue, and a single dose carries minimal risk of side effects.
This isn’t something you’d use for an ordinary sore throat. It’s a tool for situations where the pain is severe enough that swallowing liquids is difficult or sleep is significantly disrupted. It’s not appropriate for people with mono or weakened immune systems.
Medication Safety for Children
Children’s options are more limited. Ibuprofen and acetaminophen are both safe for children at weight-based doses, and ibuprofen remains the stronger choice. Beyond those two core medicines, a few rules apply:
- No aspirin under 18. Aspirin in children and teenagers has been linked to Reye’s syndrome, a rare but life-threatening condition affecting the brain and liver.
- No honey under age 1. For toddlers and older children, honey is safe and helpful for throat pain and cough.
- Skip cough and cold medicines for young children. Over-the-counter cold medicines carry real risks for small children and have limited evidence of benefit.
Salt water gargles work well for any child old enough to gargle without swallowing the water, usually around age six or seven.
Symptoms That Need Immediate Attention
Most sore throats are uncomfortable but harmless. A few warning signs, however, point to something more serious. Seek emergency care if you have difficulty breathing or difficulty swallowing liquids. See a doctor promptly if your sore throat lasts longer than a week, comes with a fever above 103°F, produces blood in your saliva, or is accompanied by visible pus on the back of your throat, a skin rash, or signs of dehydration.
