Recurring strep throat can result in pain and discomfort, lost days at school or at work, and ultimately surgery. This article will explore ways to discover why you may be experiencing recurring strep throat and what you can do about it.

What Is Recurring Strep Throat?

This actually can be a broad name for several scenarios:

  • A case of strep throat that is not cured after the first course of antibiotic treatment.
  • A person who is infected by strep throat frequently, perhaps a few times a year.
  • Lastly, a person who gets strep throat over and over and over again.
If you have had strep throat 7 or more times in one year, your doctor will usually consider performing a tonsillectomy. This makes it less likely to get strep, but some individuals still get strep throat even after their tonsils have been removed.

Experts can narrow recurring strep throat down to a few factors. One is that you have simply contracted a resistant form of the bacteria or your antibiotic has failed for some other reason. Another possibility is that you may have a weakened immune system. Another is that you are or someone in your family is a strep carrier.

When Your Antibiotic Doesn't Work

The first antibiotic choice(s) for treating strep throat is penicillin or amoxicillin. If you have a penicillin allergy penicillin or any other antibiotic in the "cillin" family will not be used, but otherwise it is the first line of defense. Individuals with penicillin allergies are often prescribed Keflex (cephalexin), clindamycin, or erythromycin. There has been reported resistance with the use of Zithromax (azithromycin).

Whether or not the first antibiotic works for you is related to timing. There is clinical evidence that individuals who receive their prescription too early (within the first 48 hours) in the course of their illness are at a higher risk for recurring strep throat. However, it is not recommended that doctors delay treatment of strep throat unless they are treating an individual with recurring strep throat.

There are many different kinds of bacteria that live in the back of the throat without making us sick and that actually fight off the bacteria that is harmful to our bodies. This bacteria is called "normal flora." Some studies have shown that the normal flora in some individuals is capable of disabling the bactericidal mechanism of penicillin and related antibiotics. In this case, another antibiotic not in the penicillin family should successfully treat your strep throat.

It is also true that most antibiotics will destroy the natural flora in the back of your throat that normally fight off harmful bacteria -- including the bacteria responsible for strep throat. This makes it very easy to contract another case of strep throat within the first month or so after your initial treatment even if the first antibiotic was successful.

Resistant strains of the bacteria responsible for strep throat are not common. In most cases, if the first course of antibiotics does not work, a new antibiotic will. If this is not the case for you, you may want to explore other explanations for your recurring strep throat.

Recurring Strep Throat Related to a Weakened Immune System

There are many diseases that can cause decreased immunity. Individuals with HIV/AIDS, who are on chemotherapy, have had organ transplants, or are taking corticosteroid medications are some examples. However, some individuals simply inherit a weak immune system. You will need to explore possibilities of a weakened immune system with your physician and then be extra diligent in practicing the following hygienic measures, (and any others recommended by your doctor). These suggestions are good practice not only for those with decreased immunity but for anyone who has had problems with recurring strep throat:

  • Wash you hands frequently. Wash for at least 15 seconds. Use antibacterial soap if you can. Use an alcohol-based hand sanitizer if soap and water is not available. Wash before and after you eat, after you use the restroom, and after entering and exiting a public place.
  • Do not share drinks or utensils with others.
  • Avoid individuals you know are ill.
  • Strep throat is most common in children ages 5 to 15 years old. As much as possible, avoid places where large numbers of kids in this age group will be. If you need to be in an area where there are a lot of children this age, wash your hands more frequently. Depending on the severity of your weakened immune system, you may consider wearing a face mask.
  • Be aware of your personal space. Crowded living conditions have been proven as culprits for the spread of strep throat.
  • Always cover your mouth when you cough or sneeze and ask others around you to do the same.
  • Inform your friends and family that you have a weakened immune system and ask them to follow good hygiene as well.

Strep Throat Carriers

A certain percentage of the population normally carries group A strep (the bacteria that causes strep throat) in the back of their throat but exhibits no symptoms. Blood tests in these individuals will also show that there is no immune response to group A strep. These people are called strep carriers.
