If you have strep throat, the most important step is getting a prescription antibiotic and taking the full course, even after you start feeling better. Strep throat is a bacterial infection that won’t resolve reliably on its own, and leaving it untreated can lead to serious complications. While you wait for the antibiotics to kick in, several home strategies can make the next few days much more bearable.
Get Tested Before You Treat
Strep throat and a regular viral sore throat can feel nearly identical, so you need a test to know which one you’re dealing with. Your doctor will typically start with a rapid strep test, which involves a quick throat swab and returns results in minutes. If that comes back positive, you’ll get a prescription right away.
If the rapid test is negative, what happens next depends on your age. For children and teenagers, a throat culture is important because the rapid test can miss some infections. The culture takes a day or two to come back but is more accurate. For adults, a throat culture after a negative rapid test is generally not necessary, since adults face a lower risk of complications.
Take the Full Course of Antibiotics
The standard treatment is a 10-day course of penicillin or amoxicillin. These are the first-choice antibiotics for strep, and they work well for the vast majority of people. If you’re allergic to penicillin, your doctor will prescribe an alternative.
Here’s where many people slip up: you’ll likely feel significantly better within two or three days of starting antibiotics, but stopping early lets surviving bacteria regroup. Finishing all 10 days is what actually clears the infection and protects you from complications. Set a daily reminder if you need to.
You become much less contagious within about 12 hours of your first antibiotic dose. That’s the standard threshold for returning to school or work, as long as your fever has also broken.
Manage Pain and Discomfort at Home
Antibiotics kill the bacteria, but they don’t do much for the sore throat pain you’re feeling right now. Over-the-counter pain relievers like ibuprofen or acetaminophen are your best tools for reducing throat pain and bringing down a fever. For children, follow the age-appropriate dosing on the package.
Gargling with warm salt water is a simple remedy that genuinely helps. Mix half a teaspoon of salt into 8 ounces of warm water and gargle for 15 to 30 seconds. You can repeat this several times a day. It won’t cure anything, but it reduces swelling in the throat tissue and provides temporary relief.
A few other things that help during recovery:
- Stay hydrated. Warm broth, herbal tea, and water keep your throat moist and prevent dehydration from fever. Cold foods like popsicles or ice chips can also soothe inflammation.
- Eat soft foods. Soups, yogurt, mashed potatoes, and smoothies are much easier to swallow than anything scratchy or acidic.
- Use a humidifier. Dry air irritates an already inflamed throat. Running a cool-mist humidifier in your bedroom can make sleeping more comfortable.
- Rest your voice. Talking strains your throat. Give it a break for a day or two if you can.
Prevent Spreading It to Others
Strep is highly contagious through respiratory droplets, so the first 12 hours on antibiotics are the critical window. During that time, avoid sharing cups, utensils, or food. Wash your hands frequently, especially after coughing or sneezing. If you can, stay in a separate room from family members who haven’t been exposed.
One often-overlooked step: replace your toothbrush within 24 hours of starting antibiotics. Your old toothbrush can harbor the bacteria, and while reinfecting yourself is debated, swapping it out is cheap insurance. Keep your toothbrush stored separately from other family members’ brushes during your illness.
Why You Shouldn’t Skip Treatment
Strep throat left untreated can trigger rheumatic fever, a serious inflammatory condition that affects the heart, joints, and nervous system. It can also lead to a kidney condition called post-streptococcal glomerulonephritis, where your immune system’s response to the strep bacteria causes inflammation in the kidneys. This typically develops about 10 days after strep symptoms begin.
Most people who develop kidney inflammation recover within a few weeks, but in rare cases it can lead to long-term kidney damage or kidney failure. These severe outcomes are more common in adults than children. Rheumatic fever is also preventable with timely antibiotics. The 10-day course exists specifically to prevent these complications, not just to make your throat feel better.
When Symptoms Need Urgent Attention
Most strep cases resolve smoothly with antibiotics, but certain symptoms signal something more serious. Difficulty breathing or an inability to swallow (not just pain when swallowing, but actually being unable to get fluids down) needs immediate medical attention. These could indicate a peritonsillar abscess, which is a pocket of infection that forms near the tonsils and can obstruct your airway.
If you’ve been on antibiotics for 48 hours and your fever hasn’t improved at all, or if your symptoms are getting worse instead of better, call your doctor. You may need a different antibiotic or further evaluation. Similarly, if you develop a new rash, joint pain, or dark or reduced urine output in the weeks after strep throat, these could be signs of the immune-related complications mentioned above and warrant a prompt call to your doctor.
