Strep Throat

What Happens

Symptoms of strep throat most often start within 2 to 5 days after you come in contact with someone who has a strep infection. Strep throat most often starts to get better in 3 to 7 days with or without antibiotic treatment.

If strep throat isn't treated with antibiotics, you can still spread the infection for a few weeks even if your symptoms go away. If you start antibiotics, within 24 hours you are much less likely to spread the infection. With antibiotics, you also are less likely to get other problems from the strep infection.

Can strep throat cause other health problems?

Problems (complications) from strep throat are rare. But they can occur, especially if your throat infection isn't treated with antibiotics. Problems can occur when the strep infection spreads to other parts of the body. This can cause other infections, such as an ear or sinus infection or an abscess near the tonsils (peritonsillar abscessperitonsillar abscess). Problems can also cause your immune systemimmune system to attack your own body. This can cause serious conditions such as rheumatic feverrheumatic fever and kidney problems.

Treating strep throat can greatly reduce your risk for rheumatic fever and other problems. It's not clear whether treating the strep infection with antibiotics lowers your risk for inflammation of the kidneys (acute glomerulonephritisglomerulonephritis).

Watchful waiting

Watchful waitingWatchful waiting is a good choice if your sore throat occurs with symptoms like those of a cold, such as sneezing, coughing, and a runny or stuffy nose.

Exams and Tests

Your doctor will examine you, ask about your symptoms, and do a throat culture or rapid strep test.

A rapid strep test analyzes the bacteria in your throat to see if strep is causing your sore throat. The doctor uses a cotton swab to gather cells from the back of your throat for testing. This test gives results within about 10 minutes. But sometimes it doesn't show strep even when you have strep. If the rapid test is positive and says that you do have strep, there's no need to do the throat culture.

A throat culture can find strep bacteria. A culture takes 1 or 2 days, but it's better at finding all cases of strep. A sample of cells from the back of your throat is added to a substance that promotes the growth of bacteria. If no bacteria grow, the culture is negative. If strep bacteria grow, the culture is positive.

Treatment Overview

Doctors usually treat strep throat with antibiotics. These drugs shorten the time that you're able to spread the disease (are contagious) to others. And they lower the risk of spreading the infection to other parts of your body. They also may help you feel better faster.

Your doctor may also advise you to take an over-the-counter medicine like acetaminophen (such as Tylenol) or ibuprofen (such as Advil or Motrin) to help with pain and lower your fever. Be safe with medicines. Read and follow all instructions on the label. Don't give aspirin to anyone younger than 20. It has been linked to Reye syndrome, a serious illness.

Self-Care

Your doctor may have prescribed an antibiotic for strep throat. Take all of the antibiotic exactly as prescribed. This will help prevent the infection from coming back and will prevent complications of infection that could occur if you do not take the medicine as prescribed.

There are many ways that you can make yourself feel better while you are waiting for the strep infection to go away.

• Stay hydrated.

  Drink plenty of fluids and increase humidity (moisture in the air) in your home to help keep your throat moist. Herbal teas formulated for colds and other warm liquids may help relieve symptoms. Frozen liquids like ice or flavored ice pops (such as Popsicles) may help too.

• Get plenty of rest.

  Stay home the first day of antibiotic treatment. You are still contagious and might pass the infection to others. Rest in bed if you feel very sick.

• Treat your symptoms.
  • Take nonprescription medicines to relieve a painful sore throat and reduce fever. Be safe with medicines. Read and follow all instructions on the label.
  • Try an over-the-counter anesthetic throat spray or throat lozenges, which may help relieve throat pain. Do not give lozenges to children younger than age 4. If your child is younger than age 2, ask your doctor if you can give your child numbing medicines.
• Protect others.

  For the first 24 hours after you start taking an antibiotic, you are still contagious so stay home. You can avoid passing the strep throat infection to others and reinfecting yourself by:

  • Avoiding sneezing or coughing on others.
  • Washing your hands often.
  • Using tissues you can throw away, not handkerchiefs.
