LuciFida 200mg, Fidaxomicin Tablets
LuciFida 200mg is a prescription antibiotic formulation that contains Fidaxomicin, an advanced macrocyclic antibacterial agent. This drug has proven efficacy specifically for treating Clostridioides difficile-associated diarrhea (CDAD), a severe and often recurring gastrointestinal infection. Its unique mechanism of action and low systemic absorption make it a targeted treatment with minimal impact on the normal gut flora.
What is LuciFida 200mg (Fidaxomicin)?
LuciFida 200mg is an oral antibacterial medication used primarily to treat infections caused by Clostridioides difficile (C. difficile). The active ingredient, fidaxomicin, belongs to the macrocyclic class of antibiotics. Unlike broad-spectrum antibiotics, Fidaxomicin offers a narrow spectrum of activity, focusing specifically on C. difficile, reducing the risk of disturbing beneficial gut bacteria.
How it Works / Mechanism of Action
Fidaxomicin functions by blocking the bacterial RNA polymerase enzyme, which is necessary for the synthesis of bacterial RNA. This inhibition disrupts transcription and protein production, leading to the death of C. difficile bacteria. It is bactericidal and acts locally in the gastrointestinal tract, which is the primary site of C. difficile colonization.
Unlike metronidazole or vancomycin, Fidaxomicin targets only C. difficile with minimal systemic absorption, reducing side effects and recurrence of infection. Its safety profile is also influenced by its low absorption rate.
How to Use / Indications
LuciFida 200mg is indicated for:
- treatment for Clostridium difficile-associated diarrhea (CDAD) in adults and children aged six months and older.
- This condition is often associated with prolonged antibiotic use and can lead to symptoms like watery diarrhea, abdominal cramping, fever, and leukocytosis. Fidaxomicin is particularly useful in patients at risk of recurrence or those who are resistant to other therapies.
How to Take / Dosage
Standard Adult Dosage:
- 200mg orally twice daily (every 12 hours) for 10 days, with or without food.
Pediatric Dosage:
- Pediatric dosing depends on weight and age. Always seek advice from a pediatric professional or reference recommendations tailored to children.

Benefits
- Narrow Spectrum: Specifically targets C. challenging with minimal interference with the typical intestinal flora.
- Low Recurrence Rate: Shows a much lower rate of recurrence than vancomycin.
- Oral Administration: Easy and convenient oral route.
- Minimal Systemic Absorption: Reduces risk of systemic side effects.
- Pediatric Use Approved: Safe for children above 6 months (in specific dosages).
- Effective in Resistant Cases: Useful when metronidazole or vancomycin fails.
These features make LuciFida an advanced and more targeted therapy in the management of CDAD.
Prescription
LuciFida is a prescription-only medication, and it should be used under the supervision of a qualified healthcare provider. It is crucial to complete the full 10-day course, even if symptoms improve earlier, to reduce the risk of recurrence.
Drug Interactions
Because of its low systemic absorption, fidaxomicin has few recognized medication interactions. However, consider the following:
- P-glycoprotein inhibitors (e.g., verapamil, cyclosporine): May increase fidaxomicin exposure.
- Antifungals and antivirals: Usually safe but still monitor for interactions.
- Immunosuppressive drugs: No significant interaction, but caution advised in patients with immune-compromised conditions.
Always inform your doctor about all other medications, supplements, or herbal products being used.
