A peritonsillar abscess (sometimes called quinsy) is treated by draining the pus collection and taking antibiotics, usually for about two weeks. Most people start feeling better within 24 hours of drainage, and full recovery typically takes about a week. The specific drainage method, antibiotic choice, and whether you need to stay in the hospital depend on the size of the abscess and how well you can swallow fluids.
How the Abscess Is Drained
Antibiotics alone rarely resolve a peritonsillar abscess once a true pus pocket has formed. The abscess needs to be physically drained, and there are two main ways this is done: needle aspiration and incision and drainage. Both are typically performed in an emergency department or outpatient clinic with local anesthesia sprayed or injected into the back of your throat.
With needle aspiration, a doctor inserts a needle into the swollen area and draws out the pus with a syringe. It’s the less invasive option and tends to cause less procedural pain. With incision and drainage, the doctor makes a small cut into the abscess and allows the pus to drain out, sometimes spreading the opening with a clamp to make sure the pocket empties fully.
A Cochrane review pooling data from 10 studies found that needle aspiration has a higher recurrence rate compared to incision and drainage, roughly 3.7 times higher. However, serious complications from either procedure are rare. Across the studies that tracked adverse events, only one case of post-procedure bleeding was reported (after incision and drainage), and recovery timelines were similar for both approaches, with no meaningful difference in how quickly people returned to eating normally. If needle aspiration fails to resolve the abscess, incision and drainage is typically the next step.
Antibiotics and Medications
After drainage, you’ll be prescribed antibiotics to clear the remaining infection. Treatment courses generally last 10 to 14 days depending on severity and how quickly you improve. The bacteria that cause peritonsillar abscesses are usually a mix of types, so the antibiotics chosen are broad-spectrum ones that cover that range. If you’re treated as an outpatient, you’ll take oral antibiotics at home. If you’re admitted to the hospital, antibiotics are given through an IV first, then switched to oral pills before discharge.
For people with penicillin allergies, alternative antibiotics are available. Your doctor will ask about allergy history before choosing a medication. If there’s concern about a resistant staph infection (MRSA), particularly if you’ve had one in the past six months, an additional antibiotic may be added to the regimen.
A single dose of a steroid given at the time of treatment can meaningfully speed up recovery. Two studies found that patients who received a steroid reported less pain and were able to drink fluids more easily within 12 to 24 hours compared to those who didn’t. The benefit faded after about 48 hours, but those early hours matter: less pain means better hydration, shorter hospital stays, and a smoother initial recovery.
Hospital Stay vs. Outpatient Treatment
Many peritonsillar abscesses can be treated and sent home the same day, especially in adults who can still swallow fluids after the procedure. Hospital admission is more likely if you’re significantly dehydrated from days of being unable to swallow, if the abscess is large or has spread beyond the tonsil area, or if there’s any concern about your airway being compromised. Children and people with weakened immune systems are also more likely to be admitted for monitoring and IV antibiotics.
If you are admitted, the stay is often brief. The steroid-assisted improvement in fluid intake within the first 12 to 24 hours frequently allows for an earlier switch to oral medications and discharge.
When Tonsillectomy Is Recommended
Most people who get a single peritonsillar abscess don’t need their tonsils removed. But the overall recurrence rate sits around 14%, and certain risk factors push that number much higher. Research published in The Journal of Laryngology and Otology identified two major predictors of recurrence: a history of recurrent tonsillitis (five or more episodes in the past year) increased recurrence risk nearly 12-fold, while spread of the abscess beyond the immediate tonsil area tripled the risk.
For people in those higher-risk categories, tonsillectomy is worth discussing. It can be done as an “interval tonsillectomy” several weeks after the abscess has fully healed, or in some cases as an immediate “quinsy tonsillectomy” at the time of the initial episode. The interval approach is more common because operating on actively infected, inflamed tissue carries additional surgical risks.
What Recovery Looks Like
Most people notice a significant drop in pain and swelling within the first 24 hours after drainage. Full recovery generally takes about a week. During that time, you’ll be finishing your antibiotic course, which lasts roughly two weeks total. Expect your throat to still be sore for several days after the procedure, though it should improve steadily rather than getting worse.
In the first few days, soft foods and cool liquids are easiest to tolerate. Things like smoothies, yogurt, broth, and ice pops keep you hydrated without irritating the area. Avoid very hot, spicy, or crunchy foods until swallowing feels comfortable. Staying well hydrated is the single most important thing you can do at home, since dehydration is one of the most common reasons people end up back in the hospital. Warm saltwater gargles can help keep the area clean and provide mild pain relief.
Most people can return to work or school within a few days to a week, depending on their comfort level and the physical demands of their day. If pain worsens after initially improving, swelling returns, you develop a fever, or you have difficulty breathing or swallowing fluids, those are signs the abscess may not have fully drained or the infection is spreading.
Complications of Untreated Abscess
A peritonsillar abscess that goes untreated or is inadequately drained can lead to serious complications. The infection can spread into the deeper spaces of the neck, potentially reaching the chest cavity, a condition called mediastinitis that requires emergency surgery. The abscess can also erode into nearby blood vessels.
One of the rarest but most dangerous complications is Lemierre syndrome, where the infection spreads to the internal jugular vein in the neck, causing a blood clot that becomes infected. From there, small infected clots can break off and travel to the lungs or other organs. Lemierre syndrome is life-threatening and requires aggressive treatment with IV antibiotics and sometimes surgical intervention. It’s diagnosed with contrast-enhanced CT imaging of the neck and chest. These severe complications are uncommon with prompt treatment, but they underscore why a peritonsillar abscess isn’t something to wait out at home hoping it resolves on its own.
