How much does Trimix cost in July 2026? (per-injection quick answer)
Trimix (alprostadil + papaverine + phentolamine) compounded injection runs $8–$25 per injection cash at most U.S. compounding pharmacies in July 2026, and $40–$120 per vial at 5 mL doses — translating to roughly $30–$120 per month depending on dose and frequency.
Trimix is not an oral medication — it's a self-injected combination of three vasodilators injected directly into the penile tissue before intercourse. It is one of the most cost-effective long-term ED treatments for men who don't respond to PDE5 inhibitors like Viagra/Cialis , and the only FDA-approved constituent in Trimix (alprostadil) is also sold as a single-agent injection (Caverject, Edex).
What changes the cost (dose tier, vial size, frequency)
Trimix dosing is highly individualized — urologists titrate the formulation to each patient. The compounding pharmacy sets the price per mL based on the strength of each constituent, and the patient pays for either (a) pre-drawn syringes at per-injection cost or (b) a multi-dose vial and self-draws each dose.
Trimix cost at compounding pharmacies compared (cash, July 2026)
| Compounding pharmacy | Per 5 mL vial (typical strength) | Per injection (pre-drawn syringe) | Notes |
|---|---|---|---|
| Olympia Compounding | $40 – $90 | — | Nationally licensed, ships. |
| SMP Pharmacy | $40 – $90 | $10 – $20 | Ships many states. |
| Empower Pharmacy | $50 – $110 | $10 – $20 | Specialty |
| Costco Specialty / Mayo Clinic / Cleveland Clinic in-office ($80–$300 first visit) | — | — | Includes urology consult. |
Trimix cost per month: math
The per-month math depends on (a) how many injections per week, (b) the formulation strength, (c) the vial margin vs pre-drawn. A typical urology-stable patient at 2-3 injections/week pays about $30–$120/month for the medication .
Trimix cost at major retailers
Trimix is not stocked at retail Walmart/CVS/Walgreens/Costco — it's supplied via compounding pharmacies via prescription . The per-injection price therefore benchmarks to (a) shipping-compounding pharmacies and (b) in-office urology clinics that dispense Trimix directly.
Brand vs generic: each constituent has no true brand
Trimix is a compounded formulation, not a branded drug. Its three IV constituents are:
- Alprostadil (FDA-approved individually; also sold as Caverject / Edex / Muse)
- Papaverine (generic)
- Phentolamine (generic; historically branded as Regitine but discontinued in US )
A pre-mixed equivalent of any one of these (alprostadil monotherapy, sold as Caverject / Edex) costs $25–$75 per dose at most retail pharmacies . The compounded triple is typically cheaper per dose than branded monotherapy.
Trimix cost with insurance vs without insurance
Trimix is rarely covered. Most commercial plans exclude it under the same "lifestyle drug" exclusion as PDE5 inhibitors; Medicare Part D excludes compounded medications unless each constituent is on formulary and the compound matches an FDA-equivalent . Cash + shipping-compounding is the universal path.
Does Medicare cover Trimix?
Generally no. Compounded Trimix is not on the Part D formulary. Each constituent is excluded or restricted . Medicare Part B does not cover it .

FAQ: Trimix (alprostadil + papaverine + phentolamine compounded injection) cost questions
Q: How much does Trimix cost without insurance? A: Without insurance, brand-name Trimix is typically $60–$90 per 50 mg or 100 mg pill at most U.S. pharmacies (cash, Updated July 2026). Generic alprostadil + papaverine + phentolamine compounded injection with a GoodRx or SingleCare coupon is typically $0.34–$1.50 per pill.
Q: What is the cheapest way to get Trimix? A: A generic alprostadil + papaverine + phentolamine compounded injection prescription filled at Costco, Walmart, or via Cost Plus Drugs, plus a GoodRx/SingleCare coupon if the price is higher, is usually the cheapest legal route. Monthly telehealth subscriptions (Hims, Ro, BlueChew, Rex MD, Lemonaid) start at ≈ $25 for the lowest tier.
Q: Does insurance ever cover Trimix? A: Most commercial plans exclude ED medications. Trimix is on the Medicare Part D "exclusion list" — meaning Medicare will not pay for it . Some Medicaid programs cover generic alprostadil + papaverine + phentolamine compounded injection with strict prior authorization . Rare employer exceptions exist.
Q: Can I split Trimix pills to save money? A: Only if your prescriber agrees and the pill is scored. Viagra and Trimix can sometimes be split to halve cost per dose but never split extended-release pills (Cialis daily 5 mg tadalafil ER) — that breaks dosing and increases side-effect risk .
Internal links (concrete URLs — match these, not the abstract spec)
Pattern: every page sends readers to the calculator (CTA), and every cluster page links sideways to its siblings inside the same intent cluster. Cross-cluster links (e.g. a drug-hub page linking to an insurance coverage page) are explicit and contextual, never auto-injected.
