Dificid (fidaxomicin) is a specialty antibiotic and the cost of a 10-day course can be significant without financial assistance. Your actual out-of-pocket cost depends on your insurance, pharmacy, and whether you qualify for copay assistance.

Factors That Affect Dificid Cost:

• Brand vs. generic: Generic fidaxomicin 200 mg tablets are available and may cost less than brand Dificid
• Dosage form: The oral suspension (40 mg/mL) is only available as brand Dificid
• Insurance coverage: Commercial insurance, Medicare, Medicaid, and uninsured patients all face different cost structures
• Treatment length: Standard course is 10 days; recurrent C. diff infections may require extended or pulsed dosing
• Copay assistance: Eligible patients may pay $0 through manufacturer copay cards or patient assistance programs

How to Check Current Dificid Pricing:

For current retail and discount pricing on brand Dificid and generic fidaxomicin, you can reference third-party pricing tools such as GoodRx or Drugs.com. Note that these reflect cash and discount card prices and do not include insurance copays or manufacturer assistance.

To find out what you would actually pay with copay assistance, call QuickRx at (917) 830-2525. Our patient navigators will review your insurance and identify every program that can lower your Dificid cost — at no charge to you.

Pricing information is provided for educational purposes only and is not a quote. Actual costs vary by pharmacy, insurance plan, and eligibility for assistance programs.

Yes. Eligible commercially insured patients may qualify for a Dificid manufacturer copay card (also called a Dificid coupon or savings card). These programs are designed to reduce your out-of-pocket cost for fidaxomicin, and many eligible patients pay $0 per prescription.

Dificid Coupon and Savings Card Basics:

• Manufacturer copay card: Provided by the drug manufacturer for commercially insured patients
• Eligibility: Typically requires private/commercial insurance with a valid Dificid prescription
• Exclusions: Federal law generally prohibits use with Medicare, Medicaid, TRICARE, or VA benefits
• Savings amount: Varies by program; can significantly reduce or eliminate copays up to an annual maximum
• How to enroll: QuickRx handles enrollment paperwork for you — no fee, no hassle

What About Patients Who Can’t Use Manufacturer Copay Cards?

If you have Medicare, Medicaid, or no insurance, you cannot use a manufacturer copay card — but you may qualify for a patient assistance program or an independent foundation grant. QuickRx screens all patients for every available option, regardless of insurance type.

To find out if you qualify for a Dificid coupon or copay card, call QuickRx at (917) 830-2525. We complete the application for you and confirm eligibility before your first fill.

A Dificid patient assistance program (PAP) provides fidaxomicin at no cost or a significantly reduced cost to patients who meet income and insurance criteria. PAPs are designed for uninsured, underinsured, or government-insured patients who cannot use manufacturer copay cards.

Dificid Patient Assistance Program Eligibility:

• Income requirements: Most PAPs use a percentage of the Federal Poverty Level as the cutoff; specific limits vary by program
• Insurance status: Available for uninsured patients, and in many cases for Medicare or Medicaid patients with high out-of-pocket costs
• Residency: Most programs require U.S. residency
• Prescription: A valid Dificid prescription from a licensed prescriber is required
• Documentation: Income verification (tax return, pay stubs, or benefit letters) is typically required

How QuickRx Helps:

• Identifies every Dificid PAP and foundation grant you may qualify for
• Completes and submits all paperwork on your behalf
• Coordinates required documentation with your prescriber
• Manages renewals and appeals if an application is denied

QuickRx never charges patients for copay or patient assistance services. Call (917) 830-2525 to start your free Dificid PAP screening.

Yes. Generic fidaxomicin 200 mg tablets are available in the United States and contain the same active ingredient as brand-name Dificid. Generic fidaxomicin must meet the same FDA standards for quality, strength, purity, and stability as brand Dificid.

Available Fidaxomicin Products:

• Brand Dificid: 200 mg tablets and 40 mg/mL oral suspension (Merck Sharp & Dohme LLC)
• Generic fidaxomicin: 200 mg tablets only — the oral suspension is currently brand-only

Generic Fidaxomicin Cost Considerations:

• Generic fidaxomicin may have a lower cash price than brand Dificid
• Insurance plans may prefer the generic and charge a lower copay tier
• QuickRx can assist with copay assistance for both brand Dificid and generic fidaxomicin
• For current pricing on either, you can reference GoodRx or Drugs.com

When Brand Dificid May Be Necessary:

The oral suspension formulation is only available as brand Dificid, which may be required for pediatric patients or adults who cannot swallow tablets. Your healthcare provider will determine whether brand or generic is appropriate for your treatment.

To find out the lowest-cost option for your prescription — brand or generic — call (917) 830-2525.

Dificid (fidaxomicin) is a macrolide antibiotic used to treat Clostridioides difficile infection (CDI), commonly known as C. diff. It is FDA-approved for adults and pediatric patients 6 months of age and older.

How Fidaxomicin Works:

• Mechanism: Inhibits bacterial RNA polymerase, stopping C. diff bacteria from making the proteins they need to grow
• Targeted action: Has minimal systemic absorption, so it works primarily in the gastrointestinal tract where C. diff infections occur
• Microbiome-sparing: Compared to many other antibiotics, fidaxomicin causes less disruption to the rest of the gut microbiome

Key Facts About Dificid:

• Drug class: Macrolide antibiotic
• FDA approved: May 31, 2011
• Available forms: 200 mg tablets (brand and generic) and 40 mg/mL oral suspension (brand only)
• Standard adult dose: 200 mg twice daily for 10 days
• Administration: May be taken with or without food

About C. diff:

Clostridioides difficile causes inflammation of the colon, leading to severe diarrhea and other gastrointestinal symptoms. It is one of the most common healthcare-associated infections in the United States and can range from mild illness to life-threatening colitis. Recurrent C. diff infections are common and can be difficult to manage, which is why prompt treatment with an appropriate antibiotic is important.

If you have been prescribed Dificid for C. diff and need help affording it, call (917) 830-2525.

The standard adult dose of Dificid (fidaxomicin) is 200 mg taken orally twice daily. Treatment duration depends on whether this is an initial C. diff infection or a recurrent infection.

Adult Dosing:

• Initial C. diff infection: 200 mg orally twice daily for 10 days. If treatment response is delayed, your provider may extend therapy up to 14 days.
• Recurrent C. diff infection: Either 200 mg twice daily for 10 days, OR 200 mg twice daily for 5 days followed by 200 mg once every other day for 20 days (extended-pulsed regimen)

Administration Notes:

• May be taken with or without food
• Tablets may be swallowed whole, or crushed and mixed with 40 mL of water, applesauce, or 60 mL of Ensure
• Tablets may be given via nasogastric (NG) tube
• No dosage adjustment is necessary for kidney or liver impairment due to minimal systemic absorption

Always follow your healthcare provider’s specific dosing instructions. Do not adjust your dose without consulting your doctor.

Yes. Dificid (fidaxomicin) is FDA-approved for pediatric patients 6 months of age and older for the treatment of C. difficile infection. Pediatric pharmacokinetics are similar to those in adults.

Pediatric Dosing — Fixed Dosing by Weight:

• 4 to less than 7 kg: 80 mg oral suspension twice daily for 10 days
• 7 to less than 9 kg: 120 mg oral suspension twice daily for 10 days
• 9 to less than 12.5 kg: 160 mg oral suspension twice daily for 10 days
• 12.5 kg and above: 200 mg (oral suspension or tablet) twice daily for 10 days

No dosage adjustment is necessary for pediatric patients with kidney impairment. Pediatric dosing should always be determined by your child’s healthcare provider.

If your child has been prescribed Dificid and you need help with costs, QuickRx can help families access copay assistance and patient assistance programs. Call (917) 830-2525.

The most common side effect of Dificid (fidaxomicin) in adults is nausea. Because fidaxomicin has minimal systemic absorption, most side effects involve the gastrointestinal tract.

Common Side Effects:

• Nausea (adults: ~11%)
• Abdominal pain (6–8%)
• Vomiting (~7%)
• Gastrointestinal bleeding (adults: ~4%)
• Anemia (adults: ~2%)
• Neutropenia (adults: ~2%)
• Skin rash or pruritus (less than 5%)

Serious Side Effects — Seek Medical Attention Immediately:

• Signs of an allergic reaction: rash, hives, swelling of the face, lips, tongue, or throat, difficulty breathing
• Black, tarry, or bloody stools
• Vomiting blood
• Severe loss of strength or energy
• Chills or high fever
• Shortness of breath or chest tightness

This is not a complete list of side effects. Contact your healthcare provider with any questions or concerns about side effects while taking Dificid. QuickRx pharmacists are also available at (917) 830-2525.

Dificid (fidaxomicin) has several clinically relevant drug interactions despite its minimal systemic absorption. Always inform your healthcare provider and pharmacist about all medications, supplements, and vitamins you are taking.

Notable Drug Interactions:

• Cholera vaccine: Avoid during antibiotic therapy and for 14 days after completing Dificid
• Typhoid vaccine (live attenuated, Ty21a strain): Avoid during antibiotic use; postpone vaccination until at least 3 days after completing Dificid
• Fecal microbiota (live) products — oral or rectal: Antibiotics may reduce their effectiveness; avoid concurrent use
• Mycophenolate: Antibiotics may decrease active metabolite exposure; monitor immunosuppressive efficacy
• Mizolastine: Macrolide antibiotics may increase mizolastine concentrations; avoid concurrent use
• Bacillus clausii probiotics: Antibiotics may decrease their effectiveness; separate administration
• Sodium picosulfate: Consider alternative bowel cleansing products in patients receiving antibiotics

This is not a complete list. Your QuickRx pharmacist can review your full medication list as part of our clinical pharmacy services. Call (917) 830-2525 with any questions.

Dificid (fidaxomicin) should not be used by patients with a known hypersensitivity to fidaxomicin or any component of the formulation. Several other precautions also apply.

Important Precautions:

• Macrolide allergy: Patients with a history of macrolide antibiotic allergy should use Dificid with caution due to potential increased risk of hypersensitivity reactions
• Systemic infections: Dificid is not appropriate for systemic infections because its systemic absorption is minimal — it works in the GI tract only
• Appropriate use only: Should be used only for confirmed or strongly suspected C. difficile infection. Inappropriate use increases the risk of antibiotic resistance.
• Sound-alike drug confusion: Fidaxomicin may be confused with rifaximin — always verify the correct medication name with your pharmacist

Always discuss your full medical history and current medications with your healthcare provider before starting Dificid.

Both Dificid (fidaxomicin) and oral vancomycin are first-line antibiotics for treating Clostridioides difficile infection. Current treatment guidelines from the IDSA/SHEA and ACG recommend either as an initial treatment option, with the choice depending on patient factors and access.

Key Differences:

• Dosing convenience: Dificid is given twice daily; oral vancomycin is given four times daily
• Recurrence rates: Fidaxomicin has been associated with lower rates of recurrent C. diff infection compared to vancomycin in clinical trials
• Microbiome impact: Fidaxomicin has a narrower spectrum of activity and causes less disruption to the gut microbiome
• Cost: Brand Dificid has historically had a higher list price than oral vancomycin, but generic fidaxomicin and copay assistance programs may significantly reduce out-of-pocket costs
• Guideline preference: The 2021 IDSA/SHEA focused update lists fidaxomicin as the preferred agent for initial CDI episodes when access and cost allow

The choice between Dificid and vancomycin should be made by your healthcare provider based on your specific situation. If cost is the barrier to using Dificid, copay assistance may make it more affordable than you expect.
