BREAKING: 2026 TrumpRx Program & Medicare Changes

Historic Price Reductions Through Government Agreement

In a landmark announcement, the Trump administration secured agreements with Eli Lilly and Novo Nordisk to dramatically reduce GLP-1 medication costs for Medicare and Medicaid beneficiaries starting in 2026.

Key Changes for Tirzepatide:

1. Medicare & Medicaid Pricing: Mounjaro and Zepbound will be available at $245 for Medicare and state Medicaid programs
2. Medicare Copay: Beneficiaries pay only $50/month
3. First-Time Coverage: Medicare will cover Zepbound for obesity patients with comorbidities for the first time

• If you're on Medicaid: Check with your state program for expanded coverage options
• Self-pay patients: TrumpRx will offer substantial discounts directly from manufacturers

Important Note: While this agreement represents significant progress, the Trump administration finalized 2026 Medicare policy in April 2025 that does not include the Biden administration's proposed expansion of Medicare coverage for anti-obesity medications beyond the specific agreements mentioned above.

Generic Tirzepatide: Does It Exist in 2026?

Short Answer: No true generic tirzepatide exists yet.

Tirzepatide is still under patent protection, meaning no FDA-approved generic version is available in 2026. However, compounded tirzepatide offers a more affordable alternative.

Compounded Tirzepatide: The Affordable Alternative

Compounded tirzepatide contains the same active ingredient as Mounjaro and Zepbound but is custom-made by licensed compounding pharmacies. Here's what you need to know:

Cost Range: $219-$599 per month Average Price: $350/month

Top Compounded Tirzepatide Providers (2026):

Compounded vs Brand-Name: What's the Difference?

Compounded Tirzepatide:

• ✅ Same active ingredient
• ✅ 50-80% cheaper than brand-name
• ✅ Can include beneficial additives (B12, glycine, etc.)
• ✅ Custom dosing options
• ❌ Not FDA-approved (individual preparations)
• ❌ Quality varies by pharmacy
• ❌ May not be covered by insurance

Brand-Name (Mounjaro/Zepbound):

• ✅ FDA-approved
• ✅ Consistent quality control
• ✅ May be covered by insurance
• ✅ Extensive clinical trial data
• ❌ Significantly more expensive
• ❌ Requires prior authorization

Is Compounded Tirzepatide Safe?

According to the FDA, compounded medications should only be used when:

1. The FDA-approved drug is unavailable
2. A patient needs a custom dose
3. A patient has allergies to inactive ingredients

Safety Tips:

• Only use licensed 503A or 503B compounding pharmacies
• Verify pharmacy credentials through your state board of pharmacy
• Look for ACHC or PCAB accreditation
• Avoid prices below $200/month (red flag for unlicensed pharmacies)
• Never buy "generic tirzepatide" - it doesn't exist

Important FDA Update: The FDA ended the shortage status for tirzepatide in early 2025. State-licensed compounding pharmacies (503A) had to stop producing compounded tirzepatide by February 18, 2025, and 503B facilities by March 19, 2025. However, compounding remains legal when medically necessary for individual patient needs.

Mounjaro vs Zepbound: Which Should You Choose?

Which is Right for You?

Choose Mounjaro if:

• ✅ You have type 2 diabetes
• ✅ You want better insurance coverage

• ✅ You have obesity with BMI ≥30 (or ≥27 with comorbidities)
• ✅ You have obstructive sleep apnea
• ✅ You have commercial insurance that covers weight loss medications

Frequently Asked Questions (FAQ)

How much does tirzepatide cost without insurance?

Without insurance, brand-name tirzepatide costs $1,079-$1,086 per month. However, you can access it for less through:

• LillyDirect self-pay: $349-$499/month
• Compounded tirzepatide: $219-$599/month
• TrumpRx (2026): ~$346/month average

Does Medicare cover Mounjaro or Zepbound in 2026?

Yes, with major changes in 2026:

• Medicare covers Mounjaro for type 2 diabetes
• Medicare now covers Zepbound for obesity with comorbidities (NEW)
• Copay: $50/month under the new government agreement
• Original Medicare still doesn't cover weight loss alone without medical necessity

What's the difference between compounded tirzepatide and brand-name?

Compounded tirzepatide contains the same active ingredient but isn't FDA-approved as a finished drug product. It's made by licensed compounding pharmacies, costs 50-80% less, and can include beneficial additives. Brand-name versions (Mounjaro/Zepbound) are FDA-approved with extensive clinical data but are significantly more expensive.

Can I use a Mounjaro or Zepbound coupon with Medicare?

No. Federal law prohibits Medicare/Medicaid beneficiaries from using manufacturer coupons or savings cards. However, the new 2026 government agreement provides reduced pricing directly through Medicare.

How long do I need to take tirzepatide?

Tirzepatide is typically a long-term treatment. Clinical studies show:

• Weight loss peaks around 72 weeks
• Most patients regain weight if they stop the medication
• Diabetes benefits require ongoing treatment
• Long-term use is generally recommended for sustained results

Annual Cost Consideration: At $349/month self-pay, expect $4,188/year. With compounded options at $219/month, annual cost drops to $2,628.

Are there alternatives to tirzepatide that cost less?

Yes, several alternatives exist:

GLP-1 Medications:

• Semaglutide (Ozempic/Wegovy): Similar pricing structure
• Liraglutide (Victoza/Saxenda): Slightly less expensive
• Dulaglutide (Trulicity): Comparable diabetes option

Oral Weight Loss Medications:

• Metformin: $4-$20/month (generic)
• Phentermine: $15-$40/month
• Contrave: $90-$200/month
• Qsymia: $150-$200/month

Note: Tirzepatide shows superior weight loss results compared to most alternatives (15-21% vs 5-10% for other medications).

Will tirzepatide be available as a generic soon?

No. Mounjaro's patents don't expire until the late 2030s. Eli Lilly has exclusivity for tirzepatide, meaning no true generic will be available for at least another 10+ years. Compounded versions remain the most affordable alternative.

Can I switch between Mounjaro and Zepbound?

Technically yes, as they contain the same active ingredient. However:

• Insurance may not cover the switch
• Your doctor must prescribe for the approved indication
• Dosing equivalence is 1:1 (same mg strength)
• Consider insurance coverage before switching

Cost Tip: If insurance covers Mounjaro but not Zepbound, ask your doctor about using Mounjaro off-label for weight loss (if you have prediabetes or metabolic syndrome).

What happens if I can't afford my tirzepatide prescription?

Options if you can't afford treatment:

1. Apply for patient assistance programs (Lilly Cares, PAN Foundation)
2. Switch to compounded tirzepatide ($219-$599/month)
3. Consider alternative GLP-1 medications (check if better coverage)
4. Look into clinical trials (free medication + monitoring)
5. Work with your doctor to try lower-cost alternatives first
6. Check if employer offers wellness program coverage

Don't Skip Doses: If you're struggling financially, talk to your doctor immediately. Intermittent dosing reduces effectiveness and increases side effects.

Is compounded tirzepatide legal in 2026?

Yes, compounded tirzepatide remains legal when:

• Prescribed for a specific patient need
• Made by licensed 503A or 503B pharmacies
• Justified as medically necessary by a provider

The FDA ended the shortage-related compounding exemption in early 2025, but pharmacies can still compound when medically justified (custom dosing, allergen-free formulations, etc.).

What's the cheapest way to get tirzepatide in 2026?

The cheapest legitimate options are:

1. Compounded tirzepatide: $219-$299/month (providers like Recovery Delivered, Hers)
2. With insurance + savings card: $25/month (if your insurance covers it)
3. LillyDirect self-pay: $349-$499/month (brand-name at reduced price)
4. TrumpRx (2026): ~$346/month when platform launches

Warning: Avoid "too good to be true" prices below $150/month—these often indicate unlicensed pharmacies or counterfeit products.
