Strep throat requires antibiotics to clear the infection, but several remedies can ease the pain while you recover. Most people start feeling better within a day or two of beginning treatment, and the full course of antibiotics takes 10 days. Here’s what actually works, from prescription treatment to home care.
Antibiotics Are the Core Treatment
Strep throat is caused by bacteria, so unlike a regular sore throat from a cold, it won’t resolve on its own. Penicillin and amoxicillin are the first-choice antibiotics recommended by the CDC. Amoxicillin is often preferred for children because it comes in a chewable tablet and tastes better as a liquid. The standard course is 10 days, and finishing every dose matters even after you feel better. Stopping early can allow the bacteria to bounce back and increases the risk of complications.
If you’re allergic to penicillin, your doctor has several alternatives. Group A Strep bacteria remain universally susceptible to penicillin, which is notable because resistance to some backup antibiotics has been climbing. UK surveillance data from the current season shows that 26% of tested strep isolates were resistant to erythromycin, up from a historical range of 8% to 18%. That makes penicillin-based antibiotics even more important as the go-to option.
Pain Relief That Actually Works
While antibiotics fight the infection, over-the-counter pain relievers handle the misery. Ibuprofen is particularly effective for throat pain. In adults, it reduced sore throat pain by 32% to 80% within two to four hours of taking it, and by 70% at six hours. In children, the relief builds more slowly, with about a 25% reduction at two hours but a 56% reduction in kids still experiencing pain after two days.
Acetaminophen (Tylenol) is also effective for both short-term and longer-term sore throat relief, and it’s a good option if you can’t take ibuprofen. You can alternate between the two if one alone isn’t enough. For children, stick to the weight-based dosing on the package and avoid aspirin entirely, as it carries a risk of a rare but serious condition called Reye’s syndrome in kids.
Home Remedies Worth Trying
These won’t replace antibiotics, but they can make the wait for relief more bearable:
- Warm salt water gargle. Half a teaspoon of salt in a cup of warm water, gargled and spit out. This reduces swelling in the throat tissue and loosens mucus. Repeat several times a day.
- Cold foods and drinks. Ice chips, popsicles, and cold water can temporarily numb throat pain. Some people find warm liquids like broth or tea with honey more soothing. Try both and go with what feels better.
- Honey. A spoonful coats the throat and has mild anti-inflammatory properties. Don’t give honey to children under one year old.
- Throat lozenges or sprays. Menthol lozenges or numbing sprays with benzocaine provide short-lived but real relief. Lozenges are a choking hazard for young children.
- Humidity. A cool-mist humidifier keeps your throat from drying out overnight, which is when pain often feels worst.
- Rest and fluids. Your body fights infection more efficiently when you’re resting and well-hydrated. Dehydration is common with strep because swallowing hurts, so sip frequently even if you don’t feel thirsty.
What to Expect During Recovery
You should start feeling noticeably better within one to two days of your first antibiotic dose. Fever typically breaks first, followed by gradual improvement in throat pain. If you’re not improving after two days on antibiotics, contact your provider because it may indicate the wrong diagnosis or, rarely, a resistant strain.
You’re considered contagious until you’ve been on antibiotics for at least 12 to 24 hours. Most public health guidelines use the 24-hour mark as the point when it’s safe to return to work or school. Before that window, the bacteria spread easily through coughs, sneezes, and shared drinks or utensils.
Getting the Right Diagnosis
Strep throat symptoms overlap heavily with viral sore throats, so a test is the only way to know for sure. The rapid strep test used in most clinics gives results in minutes and is quite reliable: it correctly identifies strep about 86% of the time and correctly rules it out 96% of the time. If the rapid test is negative but your doctor strongly suspects strep, a throat culture (which takes one to two days) can catch cases the rapid test misses.
Classic strep signs include sudden severe sore throat, pain when swallowing, fever, swollen lymph nodes in the neck, and red or white patches on the tonsils. Notably, a cough, runny nose, and hoarseness point more toward a virus. Strep is most common in children ages 5 to 15, but adults get it too, especially those around school-age kids.
Why Treatment Matters
Most strep throat would eventually clear on its own, but the reason doctors treat it aggressively is to prevent rare, serious complications. An estimated 1% to 3% of people with untreated strep infections develop rheumatic fever, an inflammatory condition that can permanently damage the heart valves. Of those who get rheumatic fever, up to 60% go on to develop chronic rheumatic heart disease. Antibiotics nearly eliminate this risk.
Other possible complications of untreated strep include peritonsillar abscess (a painful pocket of pus behind the tonsil), kidney inflammation, and spread of the infection to the sinuses or ears. These complications are uncommon with proper treatment, which is why finishing the full antibiotic course is so important, even when you feel fine by day three or four.
