How to Treat Pharyngitis: Home Remedies and Antibiotics

Most pharyngitis is viral and resolves on its own within five to seven days with simple at-home care. The key decision in treatment is whether your sore throat is caused by a virus or by bacteria, because only bacterial pharyngitis (most commonly strep throat) requires antibiotics. Everything else comes down to managing pain and staying hydrated while your body fights off the infection.

Viral vs. Bacterial: Why It Matters

Roughly 70 to 85 percent of sore throats in adults are viral. Antibiotics do nothing for viral pharyngitis. They won’t speed recovery or prevent complications. The distinction matters because bacterial pharyngitis, particularly from Group A Streptococcus, can lead to serious problems if left untreated, including rheumatic fever, kidney inflammation, and peritonsillar abscess.

Clinicians use a simple scoring system to gauge the likelihood of strep. Four criteria each earn one point: a fever of 38 °C (100.4 °F) or higher, no cough, swollen lymph nodes at the front of the neck, and white patches or swelling on the tonsils. A score of 3 or 4 suggests strep is plausible, but a rapid strep test or throat culture is still needed to confirm it. A score below 3 makes strep unlikely, and most of those cases turn out to be viral. The presence of a cough, runny nose, or hoarse voice generally points toward a virus rather than bacteria.

Treating Viral Pharyngitis at Home

Since there’s no medication that kills the virus causing your sore throat, treatment focuses entirely on relieving symptoms while you heal. The most effective tools are over-the-counter pain relievers, throat lozenges, salt water gargles, and steady fluid intake.

For pain and fever, ibuprofen and acetaminophen are both effective. Research on patients with sore throat pain found that 400 mg of ibuprofen or 1,000 mg of acetaminophen both provided meaningful relief compared to placebo. In children aged 6 to 12, ibuprofen performed slightly better than acetaminophen for symptom relief. You can alternate between the two if one alone isn’t enough, since they work through different mechanisms.

Throat lozenges containing a topical anesthetic like benzocaine can numb the area directly. One clinical trial found that combination anesthetic lozenges led to complete remission of severe throat pain in 64 percent of patients within 72 hours. Look for lozenges labeled with benzocaine or menthol at your pharmacy.

Salt Water Gargles and Honey

Gargling with warm salt water is one of the oldest sore throat remedies, and it holds up. A simple recipe is about half a teaspoon of salt (roughly 2 grams) dissolved in eight ounces of warm water. The salt creates a mildly hypertonic solution that draws excess fluid out of swollen throat tissue, helps clear mucus, and keeps the mucous membranes hydrated. Gargle for 15 to 30 seconds and spit. You can repeat this several times a day.

Honey is another option worth considering, especially for children. A Cochrane review of trials involving 265 children found honey was better than no treatment for reducing cough frequency, roughly equal to the common cough suppressant dextromethorphan, and slightly more effective than diphenhydramine. A dose of 2.5 mL (about half a teaspoon) before bedtime is a reasonable amount for children over one year old. Honey should never be given to infants under 12 months because of the risk of infant botulism from dormant bacterial spores. For adults, stirring honey into warm tea or water can soothe an irritated throat and provide a mild coating effect.

When Antibiotics Are Needed

If a rapid strep test or throat culture confirms Group A Strep, antibiotics are necessary. The first-line choices are penicillin or amoxicillin, taken for a full 10-day course. Amoxicillin is often preferred for children because it tastes better in liquid form and can be taken once daily. Finishing the entire course matters even if you feel better after a few days, because stopping early increases the risk of complications and contributes to antibiotic resistance.

One practical benefit of starting antibiotics promptly: you become non-contagious within 12 hours of your first dose. Schools and daycares typically allow children to return after that 12-hour window, provided they feel well enough. Without antibiotics, strep remains contagious for two to three weeks.

Corticosteroids for Severe Pain

For particularly painful sore throats, a single dose of an oral corticosteroid can provide additional relief on top of standard pain management. A BMJ clinical practice guideline issued a cautious recommendation for this approach, noting that one dose is safe for both adults and children five and older, whether the pharyngitis is viral or bacterial. The steroid reduces inflammation in the throat, and a single dose is not likely to cause serious side effects. This isn’t something you’d use routinely for a mild sore throat, but if your pain is severe enough that you’re struggling to swallow fluids, it’s worth discussing with your clinician.

Risks of Untreated Strep Throat

Viral pharyngitis, while miserable, almost always resolves without lasting consequences. Strep throat is a different story. Left untreated, the infection can spread beyond the throat, causing a peritonsillar abscess (a pocket of pus behind the tonsil that causes intense one-sided pain, a muffled voice, and difficulty opening the mouth) or, more rarely, infections in deeper neck spaces.

The immune-related complications are the ones that concern clinicians most. Acute rheumatic fever can develop two to four weeks after an untreated strep infection, potentially causing joint pain, heart inflammation, and involuntary movements. Scarlet fever, which produces a characteristic sandpaper-textured rash, is another post-strep complication. Acute kidney inflammation (glomerulonephritis) can also follow untreated infection. These complications are uncommon in places with easy access to antibiotics, but they’re the reason strep throat is treated aggressively rather than left to resolve on its own.

Signs That Need Prompt Attention

Most sore throats improve noticeably within five days. If yours isn’t improving by then, or if you develop a fever of 101 °F (38.3 °C) or higher that persists for several days, it’s time to get evaluated. Certain symptoms warrant more urgent attention: difficulty breathing, excessive drooling (particularly in young children), blood in your saliva or phlegm, joint pain or swelling, or signs of dehydration like dark urine and dizziness.

In younger children who can’t clearly describe their symptoms, watch for changes in eating habits (suddenly preferring only soft foods), decreased appetite, ear tugging, or repeatedly touching or pointing at their neck. These behaviors often signal throat pain or a bacterial infection that has spread to the ears.
