Strep throat requires antibiotics to clear the infection, but the right combination of medication and home care can have you feeling noticeably better within one to two days. The standard treatment is a 10-day course of penicillin or amoxicillin, and most people are no longer contagious after about 24 hours on antibiotics. While you wait for the medication to work, pain relievers, cold foods, and a few simple habits can make a real difference in how you feel.
Antibiotics Are the Core Treatment
Penicillin and amoxicillin are the first-choice antibiotics for strep throat. Both are taken for 10 days, even though you’ll likely feel better well before that. Stopping early increases the chance the bacteria survive and the infection returns. Amoxicillin is often preferred for children because it comes in a chewable tablet and tastes better than liquid penicillin.
If you’re allergic to penicillin, there are several alternatives. Your doctor will likely prescribe a cephalosporin antibiotic for 10 days, or possibly azithromycin, which has a shorter five-day course. The specific choice depends on the type of allergy you have, since some penicillin-allergic patients can still safely take cephalosporins.
In some cases, a single antibiotic injection can replace the full oral course. This is sometimes used when there’s concern about someone not finishing all 10 days of pills.
Pain Relief That Actually Works
Ibuprofen is one of the most effective over-the-counter options for strep throat pain. In adults, it reduces throat pain by 32 to 80% within the first two to four hours, and by about 70% at the six-hour mark. It works slightly less quickly in children, with about a 25% reduction after two hours, though by the second day roughly half of children report their sore throat has resolved.
Acetaminophen is another solid option, particularly for people who can’t take ibuprofen. Both medications also help bring down the fever that commonly accompanies strep. You can alternate between the two throughout the day, since they work through different mechanisms and won’t interact with each other.
Foods and Drinks That Soothe
Swallowing is often the worst part of strep throat, so what you eat matters. Soft, smooth foods are easiest to get down: soups, mashed potatoes, cooked cereal, yogurt, and scrambled eggs. Very cold foods like frozen yogurt or sherbet can also numb the throat and provide temporary relief.
Avoid anything spicy or acidic. Orange juice, tomato-based sauces, and vinegar-heavy dressings will irritate an already inflamed throat. Staying hydrated is important, especially if you have a fever, so sip water, warm broth, or herbal tea throughout the day. Some people find that warm liquids feel better, while others prefer ice water. Either is fine.
Other Home Remedies Worth Trying
Saltwater gargles are a simple, time-tested way to temporarily ease throat pain. Dissolve about half a teaspoon of salt in a cup of warm water and gargle for 15 to 30 seconds. This won’t treat the infection, but it can reduce swelling and loosen mucus.
A cool-mist humidifier in your bedroom helps keep your throat from drying out overnight, which is when many people notice their pain is worst. Honey (for anyone over age one) can coat the throat and provide short-term relief, stirred into warm tea or taken by the spoonful. Throat lozenges or hard candy work similarly by keeping saliva flowing and the throat moist.
When You Can Go Back to Normal
Current guidance says you can return to work, school, or daycare after at least 24 hours on antibiotics, as long as your fever has broken. Research supports this timeline: only about 7% of people still carry detectable bacteria after the first day of antibiotic treatment, and that drops to around 5% by day two. By the end of the first week, fewer than 3% still test positive.
Your throat will likely still feel sore for two to three days after starting antibiotics, even though the infection is already clearing. This is normal. The inflammation takes a bit longer to calm down than the bacteria take to die off. If you’re not feeling any improvement after 48 hours on antibiotics, contact your doctor, as this could mean the infection isn’t responding or the diagnosis needs a second look.
Why You Shouldn’t Skip Treatment
Strep throat occasionally resolves on its own, but leaving it untreated carries real risks. The bacteria can trigger rheumatic fever, a serious inflammatory condition that can damage heart valves, inflame joints, and affect the nervous system. It can also cause kidney inflammation, where the immune system’s response to the infection damages the kidneys’ filtering units. Other possible complications include abscesses around the tonsils, ear infections, and sinus infections.
Antibiotics dramatically reduce the chance of these complications. They also shorten the duration of symptoms and limit how long you can spread the infection to others. Strep is highly contagious through respiratory droplets, so untreated individuals can pass it along for weeks.
Preventing Reinfection at Home
Replace your toothbrush after you’ve been on antibiotics for two to three days but before you finish the full course. The bacteria can linger on bristles, and while reinfecting yourself from your own toothbrush is debated, there’s no reason to take the chance with something so easy to swap out. If you use an electric toothbrush, replace the brush head the same way.
Wash drinking glasses, utensils, and anything else that touches your mouth separately from the rest of the household’s items during the first day or two of treatment. Frequent handwashing remains the single best way to keep strep from spreading to family members. If multiple people in your home develop strep within a short window, your doctor may test everyone to identify carriers who don’t have symptoms but are still spreading the bacteria.
