Why is this medication prescribed?

Fidaxomicin is an antibiotic medication primarily prescribed for the treatment of Clostridioides difficile infection (CDI), which is a bacterial infection that causes severe diarrhea and inflammation of the colon. This infection typically occurs after the use of broad-spectrum antibiotics disrupts the normal balance of bacteria in the gut, allowing Clostridioides difficile to overgrow.

Fidaxomicin works by inhibiting the growth of Clostridioides difficile bacteria in the intestines, thereby helping to clear the infection.

How should this medicine be used?

Fidaxomicin is typically prescribed for the treatment of Clostridioides difficile infection (CDI), which is a bacterial infection that primarily affects the intestines. Here’s how Fidaxomicin is typically used:

  • Dosage: The dosage of Fidaxomicin can vary depending on factors such as the severity of the infection, the patient’s age, weight, and overall health. The standard adult dosage for Fidaxomicin is 200 mg taken orally twice daily for 10 days.
  • Administration: Fidaxomicin is available in tablet form and is taken orally. It can be taken with or without food. The tablets should be swallowed whole with a glass of water and should not be crushed, chewed, or broken.
  • Duration of treatment: The usual course of treatment with Fidaxomicin for CDI is 10 days. It’s important to complete the full course of treatment even if symptoms improve before the medication is finished. This helps ensure that the infection is fully cleared and reduces the risk of recurrence.
  • Missed Dose: If a dose of Fidaxomicin is missed, it should be taken as soon as remembered unless it is almost time for the next scheduled dose. In that case, the missed dose should be skipped, and the regular dosing schedule should be resumed. Doubling up on doses to make up for a missed one should be avoided.
  • Follow-up: After completing the course of Fidaxomicin, the healthcare provider may recommend follow-up tests or appointments to ensure that the infection has been successfully treated and to monitor for any signs of recurrence.
  • Precautions: It’s important to take Fidaxomicin exactly as prescribed by the healthcare provider. Do not share the medication with others or use it for any other condition unless instructed to do so by a healthcare professional. Be sure to inform the healthcare provider about any other medications or supplements being taken, as they may interact with Fidaxomicin.
  • Side Effects: While taking Fidaxomicin, some individuals may experience side effects such as nausea, vomiting, abdominal pain, or headache. If these side effects persist or worsen, it’s important to notify the healthcare provider.

Always consult a healthcare professional for specific instructions regarding the use of Fidaxomicin, as individual circumstances may vary.
