What Helps a Sore Throat? Remedies That Work

Most sore throats get better on their own within a few days, but the right remedies can meaningfully shorten your misery while you wait. Over-the-counter pain relievers, medicated lozenges, honey, and even plain hot drinks all have evidence behind them. The trick is knowing which ones actually perform in studies and which are more tradition than treatment, because a few popular home remedies turn out to be surprisingly weak when tested rigorously.

Why Most Sore Throats Don’t Need Antibiotics

Before diving into remedies, it helps to understand what you’re treating. The vast majority of sore throats in adults are caused by viruses, and antibiotics do nothing for a viral infection. In one study of adults with pharyngitis, viruses were found in about a quarter of patients, while the bacteria most people worry about, group A streptococcus, showed up in fewer than five percent.¹ Other bacteria accounted for additional cases, but a large share of sore throats had no identifiable pathogen at all. Plenty of non-infectious triggers can inflame your throat too, including smoking, snoring, dry air, shouting, air pollution, and acid reflux.² This matters for remedy selection because the goal, in most cases, is not killing a bug. It’s managing pain and inflammation while your body handles the rest.

Over-the-Counter Pain Relievers

If you want the single most reliable thing you can do for a sore throat, take an anti-inflammatory painkiller. Ibuprofen and acetaminophen are both widely used, but they are not equal here. A controlled trial that used sore throat pain specifically as the test model found that 400 mg of ibuprofen outperformed 1,000 mg of acetaminophen on every pain rating scale at every time point after two hours.³ The likely reason is that ibuprofen is both a painkiller and an anti-inflammatory, while acetaminophen mainly tackles pain without doing much about the swelling and irritation driving it. Naproxen and aspirin fall into the same anti-inflammatory class as ibuprofen, though head-to-head sore-throat data for those is thinner.

That doesn’t mean acetaminophen is useless. If you can’t take ibuprofen because of stomach issues, kidney concerns, or blood-thinning medications, acetaminophen still reduces pain. It’s just not the first choice when both options are on the table. Some people alternate the two, which is a reasonable approach since they work through different pathways, but check dosing limits carefully and don’t exceed the daily maximum of either.

Medicated Lozenges and Throat Sprays

Lozenges and sprays deliver active ingredients directly to your inflamed throat tissue, which gives them an edge for localized relief that a pill swallowed with water doesn’t match. The evidence base here is better than you might expect for something sold next to the candy bars at the pharmacy.

Flurbiprofen lozenges, which contain a small dose of an anti-inflammatory drug, reduced sore throat pain significantly within fifteen minutes of the first dose, with effects lasting at least two hours.⁴ Over a full day, they provided around 70 to 80 percent greater relief than placebo for throat pain and difficulty swallowing, with stronger effects in people whose symptoms were more severe.⁵ These are sold under brand names like Strepsils Intensive in many countries.

Benzydamine, another anti-inflammatory available as both a spray and a lozenge, showed pain relief starting as early as two minutes after a single use, with effects persisting for up to four hours.⁶ That speed is hard to match with a pill that needs to be absorbed through your stomach first.

Benzocaine lozenges, which work as a local anesthetic, are probably the most common option on store shelves. They numb the throat on contact, and a trial testing them found responder rates of roughly 22 to 25 percent after a single lozenge.⁷ A combination lozenge containing benzocaine alongside an antiseptic performed better, with a 64 percent improvement in complete remission within 72 hours compared to placebo.⁸ Worth noting: even placebo lozenges provide some relief, because the act of sucking stimulates saliva production, which coats and soothes the throat. Researchers on that same trial acknowledged that the placebo group also experienced pain relief, just less of it.⁸ This means that even a plain hard candy does something. A medicated lozenge simply does more.

Honey

Honey is one of the few folk remedies that holds up well when researchers test it. The World Health Organization endorses honey as a demulcent for sore throat and cough relief, based on its antimicrobial properties, wound-healing activity, and the physical coating it provides to irritated tissue.⁹ A systematic review of pediatric studies confirmed honey’s role in easing cough, which often accompanies sore throat.¹⁰ Honey works partly as a thick coating that shields raw throat tissue and partly through mild anti-inflammatory action.

A spoonful of honey on its own helps, but stirring it into a warm drink may be even better. A study comparing a hot fruit drink to the same drink at room temperature found that the hot version provided immediate and sustained relief from sore throat, cough, runny nose, sneezing, chilliness, and tiredness, while the room-temperature drink helped only with runny nose, cough, and sneezing.¹¹ The heat itself appears to contribute, probably by increasing blood flow to the throat and promoting a soothing sensory effect. So tea with honey is more than just comfort. The warmth adds something the honey alone doesn’t.

One important caveat: never give honey to children under one year old, due to the risk of infant botulism. For everyone else, it’s cheap, widely available, and genuinely helpful.

Salt Water Gargling

Gargling with warm salt water is probably the most recommended home remedy for sore throat. Ask any grandparent. The rationale usually offered is that salt draws out fluid from swollen tissue through osmosis and creates a hostile environment for bacteria. In practice, many people do report feeling better after gargling, and the warm water itself likely provides some of the same soothing effect seen in the hot drink study mentioned above.

However, the hard evidence is thinner than you’d expect for something so universally recommended. A lab study testing salt water against SARS-CoV-2 found that even a relatively concentrated salt solution had no virucidal activity against the virus.⁹ That’s one virus and one study, so it doesn’t prove salt water is worthless, but it does challenge the idea that it’s actively killing pathogens. The mechanical action of gargling may help wash away mucus and debris, and the warmth is soothing. But if you’re expecting antimicrobial action, the evidence doesn’t strongly back that up. Salt water gargling is low-risk and low-cost, so there’s little reason not to do it, just don’t count on it as your primary treatment.

Menthol and Its Cooling Trick

Menthol, found in peppermint and many over-the-counter throat products, creates a cooling sensation that feels like relief even though it doesn’t change the actual temperature of your throat. It works by activating a cold-sensing receptor called TRPM8, which triggers the same neural signal your body uses to detect cold temperatures.¹² That cooling sensation also has mild analgesic properties, essentially tricking your nervous system into paying attention to “cold” instead of “pain.”

Menthol also has cough-suppressing effects, though the mechanism is somewhat paradoxical. TRPM8 receptors activated by menthol in the nasal passages send signals that can dampen cough reflexes, a phenomenon researchers have studied by exposing animals to menthol vapor and observing reduced cough responses.¹³ If your sore throat comes with a persistent cough, menthol lozenges or vapor rubs pull double duty. On its own, menthol won’t reduce inflammation or speed healing, but the sensory relief is real and can make sleeping and swallowing noticeably more comfortable.

Marshmallow Root and Demulcent Herbs

Marshmallow root (the plant, not the candy) has a long history in traditional medicine for throat complaints. The evidence base is modest but the mechanism is straightforward: the root contains polysaccharides that form a gel-like coating when they dissolve in water. This coating sticks to the mucosal lining of the throat and acts as a physical barrier against mechanical irritation and microbial contact.¹⁴ Lab work has also shown anti-inflammatory and antioxidant effects on immune cells, though whether those translate meaningfully to the human throat at typical doses is less clear.

Marshmallow root is widely available as a tea, throat coat ingredient, or supplement. It sits in the same category as honey and other demulcents: safe, cheap, and plausibly helpful through coating and soothing action, even if the clinical trial evidence for it specifically lags behind what exists for ibuprofen or medicated lozenges.

Corticosteroids for Stubborn Cases

For sore throats severe enough to send you to a doctor, a short course of corticosteroids is sometimes used alongside other treatments. Dexamethasone is the most commonly studied option. A trial of adults with acute sore throat found that a single dose of oral dexamethasone resulted in pain relief about four hours sooner than placebo, with significantly greater pain reduction at both 12 and 24 hours.¹⁵

A larger trial found that the difference at 24 hours was not quite statistically significant: about 23 percent of those given dexamethasone had complete symptom resolution versus roughly 18 percent on placebo. By 48 hours, though, the gap widened and reached significance, with about 35 percent in the dexamethasone group achieving full resolution compared to 27 percent on placebo.¹⁶ A clinical practice guideline synthesizing this evidence concluded that corticosteroids probably increase the chance of complete pain resolution at 24 hours and do increase it at 48 hours.¹⁷

This is not something to reach for routinely. Corticosteroids carry side effects and are prescription medications. But for a genuinely debilitating sore throat, especially one keeping you from eating or sleeping, asking your doctor about a short steroid course is a reasonable conversation to have. One review noted that some non-antibiotic treatments may actually be more effective than antibiotics for acute sore throat, though it cautioned that publication bias could exaggerate the benefits.¹⁸

Zinc Lozenges

Zinc gets a lot of attention as a cold remedy, and since most sore throats happen during colds, people naturally wonder whether it helps. Lab studies show zinc can inhibit the replication of respiratory viruses and boost interferon activity.¹⁹ The real-world picture is murkier. A controlled trial of zinc acetate lozenges found that while clinical symptoms improved, the difference in inflammatory cytokine levels between the zinc and placebo groups was not statistically significant.²⁰ That leaves open the question of whether zinc is truly reducing the throat infection or just modestly shortening the overall cold.

If you want to try zinc lozenges, the evidence suggests they work best when started within the first 24 hours of symptom onset. The formulation matters: zinc acetate and zinc gluconate have the most data behind them. Common side effects include a bad taste and nausea, which is why many people quit before finishing a course. Zinc is not a cure, but it may shave a day or so off your cold, and that day matters when your throat feels like sandpaper.

Humidified Air

Running a humidifier or sitting in a steamy bathroom is standard advice for sore throats, especially those that worsen overnight when indoor air is driest. The logic is sound: dry air dehydrates your throat mucosa, making irritation worse, and moist air should counteract that. But when researchers tested heated humidified air in controlled trials, the results were uncertain. A Cochrane review found that in one analysis there appeared to be an effect, but a different statistical approach to the same data showed no significant benefit. One trial even found worsened nasal resistance in the treatment group.²¹

This doesn’t mean your humidifier is useless. These trials specifically tested heated steam delivered directly to the airway, not the general effect of keeping room humidity at a comfortable level. Keeping your bedroom from dropping below about 30 percent humidity during winter is good practice for throat comfort, even if dedicated steam inhalation hasn’t proven itself in trials. Just skip the boiling-water-and-towel approach, which carries a real burn risk with no proven benefit over simpler measures.

When a Sore Throat Keeps Coming Back

If your sore throat is recurring or persistent, the usual remedy toolkit may not address the root cause. Chronic sore throat has a different set of common culprits than acute sore throat. A study cataloging the causes found that chronic tonsillopharyngitis, gastroesophageal reflux disease, and laryngopharyngeal reflux were the most frequent diagnoses. Allergies, thyroid problems, diabetes, oral conditions, and even psychiatric illnesses also appeared in the mix.²²

Acid reflux is a particularly sneaky offender. Many people with laryngopharyngeal reflux don’t have classic heartburn at all. Instead, stomach acid creeps up to the throat during sleep or after meals, causing irritation that gets blamed on recurring infections. If you’re gargling salt water every few weeks and popping lozenges on a regular cycle, it’s worth investigating whether reflux, allergies, or an environmental irritant is the actual problem. Treating the underlying cause in those cases matters far more than any topical remedy.

When to See a Doctor

Most sore throats resolve in three to five days without medical intervention. But a few warning signs warrant a visit rather than another cup of tea:

Difficulty breathing or swallowing saliva: These can signal epiglottitis or a peritonsillar abscess, both of which can progress quickly. A case series described patients presenting with acute sore throat and difficulty swallowing who were found to have swollen epiglottis and peritonsillar abscess, requiring urgent intervention.²³
Throat pain lasting more than a week: Most viral sore throats peak around day two or three and then improve. A sore throat that gets progressively worse after four or five days, or that lingers beyond seven, deserves evaluation.
High fever with no cough: Fever above about 101°F combined with tonsillar swelling and absence of cough fits the pattern clinicians look for when suspecting strep throat. Clinical scoring tools used to assess strep likelihood gain specificity when several of these signs cluster together.²⁴
Unilateral swelling or a muffled voice: A sore throat that’s markedly worse on one side, especially with trismus (difficulty opening your mouth), can indicate an abscess forming near the tonsil.

Strep throat specifically matters because untreated group A streptococcal infections can, in rare cases, lead to rheumatic fever or kidney complications. But the clinical prediction tools doctors use aren’t perfect. A meta-analysis of the Centor and McIsaac scoring systems found that while higher scores do raise the probability of strep, there is substantial uncertainty and variation across studies, with wide confidence intervals at most thresholds.²⁵ A rapid strep test or throat culture is the only way to confirm the diagnosis. If your doctor suspects strep and confirms it with a test, antibiotics are appropriate. For everything else, the remedies above are your best bet.

Putting Together a Practical Game Plan

If you want to combine these approaches intelligently, think of it in layers. Your baseline should be an anti-inflammatory painkiller like ibuprofen, taken on schedule rather than waiting for pain to build back up. Between doses, use medicated lozenges for localized relief, choosing one with an active anti-inflammatory or anesthetic ingredient rather than a plain mentholated cough drop. Sip warm drinks with honey throughout the day. Run a humidifier at night if your bedroom air is dry. These four measures, none of them exotic, cover the full range of what has good evidence behind it. Salt water gargling and menthol vapor are fine additions if they make you feel better, but they’re supporting acts, not headliners. If symptoms are severe enough that this combination doesn’t let you function, that’s when a conversation about corticosteroids with a doctor makes sense, and when ruling out strep or other complications becomes genuinely important.
