Prophylactic Treatment of Rheumatic Fever: What Medication is Used?

Rheumatic fever is a potentially deadly condition that can affect people of all ages. Fortunately, there are medications available that can help to prevent the onset and progression of the disease. The prophylactic treatment of rheumatic fever involves the use of antimicrobial agents that target the bacteria that cause the condition.

One of the most common medications used for prophylactic treatment is penicillin. This antibiotic is effective at killing the bacteria that cause rheumatic fever, helping to prevent infections and complications from developing. Other medications that may be used for prophylaxis include erythromycin, azithromycin, and clindamycin.

It’s important to note that prophylactic treatment is only effective if started early and taken consistently. Patients who have a history of rheumatic fever, as well as those who live in areas with high rates of the disease, should be monitored closely by a healthcare provider and given appropriate medications as needed. With the right treatment and management, it’s possible to prevent the progression of rheumatic fever and improve the overall health and wellbeing of patients.

Causes and Symptoms of Rheumatic Fever

Rheumatic fever is a type of inflammatory condition that can develop after a strep throat infection, which is caused by the Streptococcus bacteria. This bacterial infection can cause the body to produce antibodies that cross-react with its own tissues, leading to inflammation, particularly in the heart, joints, skin, and brain. The exact mechanism of how this happens is not entirely clear, but it is thought to involve molecular mimicry, wherein the bacterial antigens resemble human proteins, and the immune system cannot distinguish between them, leading to an autoimmune response.

  • The most common symptoms of rheumatic fever include:
  • Fever
  • Joint pain and swelling
  • Redness and swelling of the skin
  • Shortness of breath or chest pain
  • Fatigue and weakness
  • Stomach pain and vomiting
  • Involuntary movements of the limbs or face, called Sydenham’s chorea

Not all people who have a strep throat infection develop rheumatic fever, and some people may have a genetic predisposition to it. It is more common among children between the ages of 5 and 15, especially in developing countries with poor sanitation and overcrowding. Untreated or undertreated strep throat infections are a major risk factor for rheumatic fever, so prompt diagnosis and treatment with antibiotics are crucial in preventing its complications.

Diagnosis of Rheumatic Fever

Rheumatic fever is a serious inflammatory condition that can affect the heart and other organs. It often occurs after an untreated streptococcal infection. The diagnosis of rheumatic fever is based on a combination of clinical signs and laboratory findings.

  • The clinical signs of rheumatic fever include fever, joint pain, swollen and red joints, skin rash, and heart murmur.
  • Laboratory findings such as elevated erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels, abnormal electrocardiogram (ECG) and echocardiography (Echo) results, and positive streptococcal serology support the diagnosis.
  • Certain criteria have been established to diagnose rheumatic fever, including the revised Jones criteria for rheumatic fever diagnosis, which consider the presence of two major or one major and two minor criteria.

The major criteria include:

  • Carditis
  • Polyarthritis
  • Chorea
  • Erythema marginatum
  • Subcutaneous nodules

The minor criteria include:

  • Arthralgia
  • Fever
  • Elevated acute-phase reactants (ESR, CRP)
  • Prolonged PR interval on ECG
  • Prior rheumatic fever or rheumatic heart disease
  • Positive streptococcal serology

Diagnosis of rheumatic fever is important, as it can lead to severe complications and long-term sequelae in untreated or inadequately treated patients. Early diagnosis and treatment can prevent serious complications, such as rheumatic heart disease, which can permanently damage the heart valves and can lead to heart failure and death.


The treatment of rheumatic fever consists of antibiotic therapy to eradicate the streptococcal infection, as well as anti-inflammatory medications to treat the inflammation. Penicillin is the preferred antibiotic, and it is given for at least ten days. Patients with known penicillin allergy can be treated with other antibiotics, such as erythromycin.

Medication Dosage
Aspirin 60-100 mg/kg/day in divided doses for 2-6 weeks
Corticosteroids Used in severe cases or when there is carditis or heart failure

Regular follow-up with a healthcare provider is necessary to monitor symptoms and assess the progression of the disease, especially for patients with significant heart involvement or at high risk for recurrent rheumatic fever.

Antibiotics Used for Treatment of Rheumatic Fever

Prophylactic treatment with antibiotics is essential in the prevention of rheumatic fever, as it targets the bacterial infection that causes the condition. The most commonly used antibiotics in treating rheumatic fever include:

  • Penicillin: This antibiotic is the first-line treatment for prophylaxis against rheumatic fever. It works by killing the bacteria responsible for the infection and preventing the development of rheumatic fever. Penicillin can be administered orally or by an injection.
  • Macrolides: Macrolide antibiotics, such as erythromycin, clarithromycin, and azithromycin, are also effective in preventing rheumatic fever. These antibiotics disrupt bacterial protein synthesis, which prevents the bacteria from multiplying and spreading throughout the body.
  • Cephalosporins: Cephalosporin antibiotics, such as cephalexin and cefaclor, are another option for prophylactic treatment of rheumatic fever. Like penicillin, cephalosporins work by inhibiting bacterial cell wall synthesis and killing the bacteria.

Antibiotic Dosage for Prophylaxis

The dosage and duration of prophylactic treatment with antibiotics depend on the patient’s age, weight, and medical history, as well as the severity of the condition. In general, patients with a history of rheumatic fever should receive regular prophylactic antibiotics to prevent future episodes of the disease.

For penicillin, the most commonly used antibiotic for prophylaxis, the dosage and frequency of administration depend on the patient’s age and weight. In children, a single dose of penicillin is usually given every one to four weeks, while adults may receive monthly injections or daily oral antibiotics.

Antibiotic Resistance

Antibiotic resistance is a growing concern in the treatment of rheumatic fever. Overuse or misuse of antibiotics can lead to the development of antibiotic-resistant strains of bacteria, making it more difficult to treat infections and prevent the recurrence of rheumatic fever.

Antibiotic Resistance
Penicillin Low resistance
Macrolides Low resistance
Cephalosporins Low resistance

To mitigate the risk of antibiotic resistance, it is important to use antibiotics only when necessary and to complete the full course of treatment as prescribed by a healthcare provider. Patients should also discuss any concerns about antibiotic resistance with their healthcare provider and explore alternative treatment options if appropriate.

Long-Term Management of Rheumatic Fever

Rheumatic fever is a serious condition that requires long-term management to prevent complications and recurrence of the disease. The following are some of the ways to manage the disease in the long term:

  • Antibiotics: Antibiotics are used to prevent the recurrence of streptococcal infections, which can cause a recurrence of rheumatic fever. The medication is usually taken for a few years or until adulthood to prevent complications.
  • Pain Management: Pain management is an important aspect of long-term management of rheumatic fever. Pain can be managed by using over-the-counter pain relief medications like aspirin and ibuprofen.
  • Regular Follow-up: Regular follow-up visits with the doctor are essential to ensure appropriate treatment and to monitor the condition for any signs of complications.

In addition to the above, lifestyle changes can also help manage the condition. Patients are advised to maintain a healthy weight, avoid smoking and alcohol, and adopt a healthy diet. Also, during the acute phase of the disease, movement is restricted to prevent further damage to the heart.

Prophylactic Treatment

Prophylactic treatment is used to prevent the occurrence or recurrence of rheumatic fever. The table below illustrates the medications used for the prophylactic treatment of rheumatic fever.

Drug Dose Frequency
Penicillin G benzathine 1.2 million units Every 4 weeks
Sulfadiazine or sulfisoxazole 500 mg Twice daily
Penicillin V 250 mg Twice daily

Prophylactic treatment is usually administered for several years, and sometimes even decades, depending on the patient’s condition. In addition to medication, regular follow-up visits with the healthcare provider are essential to monitor the effectiveness of the treatment and to adjust the dosage as necessary.

Complications of Rheumatic Fever

While rheumatic fever can cause damage to various parts of the body, the most common complications involve the heart and the joints. Understanding the potential complications of rheumatic fever can help patients and healthcare providers monitor for and prevent long-term damage. Listed below are some of the most common complications:

  • Rheumatic Heart Disease: This is the most serious complication of rheumatic fever, occurring in up to 60% of untreated cases. It can cause permanent damage to the heart valves, resulting in impaired blood flow and, in severe cases, heart failure or stroke.
  • Joint Pain and Swelling: The characteristic joint pain and swelling of rheumatic fever can become chronic, leading to joint damage and disability.
  • Subcutaneous Nodules: These are small, painless lumps that can form under the skin, usually over bony prominences like the elbows or knees. While they usually go away on their own, they can leave permanent scars.

Other less common complications include:

  • Chorea: This is a neurological disorder that causes involuntary movements and can affect speech and cognitive function. It occurs in about 10-20% of cases, usually in children.
  • Pericarditis: Inflammation of the lining around the heart that can cause chest pain and difficulty breathing.
  • Cutaneous Vasculitis: Inflammation of small blood vessels in the skin, causing a distinctive rash.

It is important to note that the risk of complications is greatly reduced with prompt and effective treatment of rheumatic fever. Regular follow-up care with a healthcare provider is crucial to monitor for and manage any potential long-term damage.

Complication Description
Rheumatic Heart Disease Permanent damage to the heart valves, causing impaired blood flow and potential heart failure or stroke
Joint Pain and Swelling Chronic joint pain and swelling that can lead to joint damage and disability
Subcutaneous Nodules Small, painless lumps that can form under the skin and may leave permanent scars
Chorea Neurological disorder causing involuntary movements and affecting speech and cognitive function
Pericarditis Inflammation of the lining around the heart, causing chest pain and difficulty breathing
Cutaneous Vasculitis Inflammation of small blood vessels in the skin, causing a distinctive rash

It is crucial for patients with a history of rheumatic fever to be aware of the potential complications and to seek regular medical care for monitoring and treatment.

Prevention of Rheumatic Fever Recurrence

Rheumatic fever is a serious condition that can cause long-term damage to the heart, joints, and other organs. Once a person has had rheumatic fever, there is a risk of recurrence, especially if they have not received adequate treatment or have not taken prophylactic medication as prescribed.

  • Prophylactic antibiotics are the most common medication used to prevent the recurrence of rheumatic fever. Antibiotics such as penicillin or erythromycin are taken for a period of time (usually 5 years) to reduce the risk of developing further infections. This treatment is very important as it helps to prevent Streptococcus bacteria from growing and spreading in the body, which can cause new episodes of rheumatic fever.
  • In some cases, anti-inflammatory medications such as aspirin or corticosteroids may be prescribed to help reduce inflammation and relieve symptoms. However, these medications are not used as first-line treatment for the prevention of recurrence and are usually only used in combination with antibiotics if necessary.
  • A lifestyle change including a healthy diet, regular exercise, and avoiding smoking can also help to prevent the recurrence of rheumatic fever. A healthy lifestyle can improve overall health and reduce the likelihood of infections that can lead to further episodes of rheumatic fever.

Prophylactic antibiotics are the most effective form of treatment for the prevention of rheumatic fever recurrence. It is important to take medication as prescribed to ensure the best possible outcome and to reduce the risk of developing long-term complications.

Medication Dosage Duration Side Effects
Penicillin VK 250-500 mg twice daily 5 years or until age 21 (whichever is longer) Allergic reactions, gas, diarrhea, stomach pain
Erythromycin 250-500 mg twice daily 5 years or until age 21 (whichever is longer) Stomach pain, diarrhea, nausea, vomiting
Sulfadiazine 1 gram twice daily 5 years or until age 21 (whichever is longer) Rash, fever, stomach pain, nausea, vomiting

In summary, prophylactic antibiotics are the primary medication used for the prevention of rheumatic fever recurrence. It is important to take medication as prescribed and to maintain a healthy lifestyle to minimize the risk of developing further episodes of rheumatic fever.

Current Research on Rheumatic Fever Treatment

Rheumatic fever is a serious inflammatory disease that can occur after a streptococcal infection such as strep throat or scarlet fever. It most commonly affects children and can lead to heart damage if left untreated. Prophylactic treatment with medication is necessary to prevent recurrent episodes of rheumatic fever.

  • Penicillin is the most common medication used for prophylactic treatment of rheumatic fever. It is usually given orally or by injection every four weeks to prevent the recurrence of strep infections.
  • Erythromycin is an alternative medication for those who are allergic to penicillin, but it is not as effective and requires more frequent dosing.
  • Long-acting penicillin, such as benzathine penicillin G, is sometimes given once every three weeks as an alternative to monthly injections.

Despite the availability of effective prophylactic medication, research is ongoing to develop new treatments for rheumatic fever. Some current areas of research include:

  • Antibiotic resistance: As streptococcal infections become more resistant to antibiotics, researchers are investigating alternative treatments such as vaccines and immunotherapies.
  • Immunotherapy: Some studies have shown promising results using intravenous immunoglobulin (IVIG) to treat acute rheumatic fever, but more research is needed to determine its effectiveness for prophylactic treatment.
  • Biomarkers: Researchers are looking for biomarkers that can help predict the risk of developing rheumatic fever and guide treatment decisions.

A recent clinical trial published in the New England Journal of Medicine found that a combination of long-acting penicillin and azithromycin was more effective than penicillin alone for preventing the recurrence of strep infections in children with a history of rheumatic fever. This could lead to changes in current prophylactic treatment guidelines.

Medication Dosage Frequency
Penicillin 500 mg Oral or injection every 4 weeks
Erythromycin 250 mg Oral every 12 hours
Benzathine penicillin G 1.2 million units Injection every 3 weeks

Overall, current research on rheumatic fever treatment is focused on developing more effective and personalized treatments. With ongoing research and clinical trials, we can hope to improve outcomes for those affected by this serious disease.
