Antibiotic Use Before Surgery for Mitral Valve Prolapse: What You Need to Know

Antibiotics administration before surgery for mitral valve prolapse?

Hello, Director He.
Previously, an echocardiogram revealed that I have mitral valve prolapse, along with mild regurgitation of the mitral valve, tricuspid valve, and aortic valve.
At that time, I was advised that for dental procedures or any surgery that may involve bleeding, I should take antibiotics beforehand to prevent endocarditis.
May I ask: 1.
What type of antibiotics should I purchase? 2.
Where can I buy them without a prescription? 3.
Is the timing for taking them one hour before the surgery? Thank you for taking the time to answer my questions.

Hello, you don't need to worry about this.
Just inform the physician who is arranging your dental surgery or any other procedure that may involve bleeding to prescribe you an immediate dose to be taken one hour before the surgery to prevent endocarditis.

More Info

When it comes to the use of antibiotics before surgery for patients with mitral valve prolapse (MVP), especially those with associated mild regurgitation, there are several important considerations to keep in mind to prevent infective endocarditis.
1. Type of Antibiotics: The most commonly recommended antibiotic for prophylaxis in patients with MVP undergoing dental or other invasive procedures is Amoxicillin. The standard prophylactic dose is typically 2 grams taken orally one hour before the procedure. If you are allergic to penicillin, alternatives such as Clindamycin or Azithromycin may be prescribed. It is crucial to consult with your healthcare provider to determine the most appropriate antibiotic based on your medical history and any allergies.

2. Where to Purchase: Antibiotics like Amoxicillin generally require a prescription from a healthcare provider. If you do not have a prescription, you will need to consult with your doctor or a dentist who can evaluate your condition and provide the necessary prescription. In some cases, pharmacists may be able to provide guidance on over-the-counter options, but for antibiotics, a prescription is typically required.

3. Timing of Administration: The ideal timing for taking the antibiotic is indeed one hour prior to the surgical procedure. This timing helps ensure that adequate levels of the antibiotic are present in your bloodstream during the procedure, which is critical for effective prophylaxis against potential bacterial infections that could lead to endocarditis.

In addition to these points, it is essential to communicate any side effects you may experience while taking antibiotics, such as the symptoms you mentioned (increased heart rate, fatigue, and cloudy urine). These could be signs of an adverse reaction or an indication that the antibiotic is not well-tolerated by your body. If you experience significant discomfort or unusual symptoms, you should contact your healthcare provider immediately for further evaluation.

Moreover, it is important to complete the full course of antibiotics if prescribed post-operatively, even if you feel better. This ensures that any potential residual bacteria are eliminated and reduces the risk of developing antibiotic resistance.

Lastly, while the use of prophylactic antibiotics is a standard practice for patients with certain heart conditions undergoing procedures that may introduce bacteria into the bloodstream, it is always best to follow the specific recommendations of your healthcare provider. They will consider your individual health status, the nature of the procedure, and any other relevant factors to provide tailored advice.

In summary, for patients with mitral valve prolapse, the use of antibiotics like Amoxicillin before procedures is a critical preventive measure against infective endocarditis. Always consult with your healthcare provider for personalized recommendations, and ensure you follow their guidance on timing and dosage for optimal safety and effectiveness.
