The right medication for swollen tonsils depends on what’s causing the swelling. Most cases are viral, meaning no antibiotic will help and the focus shifts to managing pain and inflammation until your body clears the infection. Bacterial tonsillitis, most commonly from strep, does require a prescription antibiotic. Either way, over-the-counter pain relievers are the foundation of feeling better.
Pain Relievers: Your First Line of Defense
Whether your swollen tonsils come from a virus or bacteria, ibuprofen and acetaminophen are the go-to medications. Both reduce pain effectively, but ibuprofen has an edge: it’s an anti-inflammatory, so it can help bring down the swelling itself, not just mask the discomfort. Research comparing the two consistently shows ibuprofen is at least as effective as acetaminophen for moderate to severe pain, and several studies suggest it works better.
For children, both medications are safe at standard doses. Aspirin is a different story. Children and teenagers should never take aspirin during a viral illness because of the risk of Reye’s syndrome, a rare but serious condition that causes swelling in the liver and brain. Salicylate, the active ingredient in aspirin, also hides in some other over-the-counter products, so check labels carefully.
When You Need Antibiotics
Antibiotics only help if bacteria are causing the infection. The most common culprit is group A strep, which your doctor can confirm with a rapid strep test or throat culture. If the test comes back positive, the CDC recommends penicillin or amoxicillin as the first choice. A typical course lasts 10 days, and finishing the full course matters even once you start feeling better.
If you’re allergic to penicillin, there are several alternatives. Your doctor may prescribe a cephalosporin antibiotic, clindamycin, azithromycin, or clarithromycin depending on the type of allergy you have. Azithromycin has a shorter course of five days, which can be more convenient, but it’s reserved for people who can’t take penicillin-based options.
If the cause is a virus, there is no medicine to treat the infection itself. You manage the symptoms and wait it out, which typically takes five to seven days.
Throat Sprays and Lozenges
Topical options can provide fast, temporary relief right where it hurts. Throat sprays containing phenol numb the throat on contact. Adults and children over three can use one spray to the affected area every two hours as needed. The relief is short-lived but can make swallowing food or water much more bearable.
Benzydamine, available as a mouthwash, spray, or lozenge, goes a step further. It’s a topical anti-inflammatory that reduces both pain and swelling in the mouth and throat. Symptoms typically start improving within minutes of use, and the effects last a few hours. The mouthwash form is only appropriate for ages 13 and up, but the spray can be used in younger children at lower doses.
Corticosteroids for Severe Swelling
When tonsils are severely swollen, especially with visible white patches or pus, a doctor may prescribe a short course of corticosteroids like dexamethasone or prednisone alongside other treatments. A Cochrane review of eight clinical trials found that corticosteroids significantly reduced throat pain in patients with severe or exudative sore throat, whether given as a single dose or over multiple days, and whether taken orally or by injection. These aren’t something you’d take on your own. They’re an add-on your doctor might use when basic pain relievers aren’t cutting it and the swelling is making it hard to eat or drink.
Home Remedies That Actually Help
Salt water gargling is one of the oldest sore throat remedies, and it holds up. A concentration of about half a teaspoon of salt in eight ounces of warm water creates a mildly hypertonic solution that draws fluid out of swollen tissue. Research has also shown that higher salt concentrations boost the antiviral activity of the cells lining your throat by interfering with viral replication. Gargle for 15 to 30 seconds and repeat several times a day.
Honey is another option worth taking seriously. A systematic review and meta-analysis found that honey was superior to usual care for relieving symptoms of upper respiratory tract infections, with a meaningful improvement in combined symptom scores across multiple studies. You can take it straight, stir it into warm tea, or look for honey-based lozenges. One important caveat: honey should never be given to children under one year old due to the risk of botulism.
Signs That Need Urgent Attention
Most swollen tonsils resolve on their own or with the treatments above. But certain symptoms point to a peritonsillar abscess, a pocket of pus that forms next to the tonsil and can become dangerous. Watch for pain that’s clearly worse on one side, a muffled or “hot potato” voice, difficulty opening your mouth, drooling, or a visibly shifted uvula. Ear pain on the affected side is another common sign.
If tonsils swell so much they nearly touch in the middle (sometimes called “kissing tonsils”), that’s an airway concern that warrants emergency care. The same goes for signs of dehydration from being unable to swallow fluids, or any indication of spreading infection like high fever with neck stiffness or swelling extending beyond the throat.
