The single most powerful thing a patient can do to protect themselves from the 2026 pharmaceutical tariff is switch from a brand-name drug to its generic equivalent. Generics are fully exempt — 0% tariff, no matter what. And with the tariff effective dates approaching (July 31 and September 29, 2026), the window to act proactively is open right now.
Here is a step-by-step guide to finding a generic for your medication and making the switch before it matters.
Step 1: Check the FDA Orange Book or Purple Book
The FDA maintains two free public databases that tell you whether any generic or biosimilar has been approved for your medication:
- FDA Orange Book — For traditional small-molecule drugs (tablets, capsules, liquids). Search by brand name to see all approved generic equivalents and their manufacturers.
- FDA Purple Book — For biologic drugs (injections, infusions). Search by reference product to find approved biosimilars.
Both are free to search at fda.gov. If a generic appears in these books, it has passed FDA standards for safety, efficacy, and quality — it is medically equivalent to the brand.
Step 2: Ask Your Pharmacist First
Before calling your doctor, ask your pharmacist a direct question: "Does a generic exist for [drug name], and do you carry it?"
Pharmacists have real-time formulary access. They know which generics are in stock, which are on backorder, and — critically — which ones your insurance will cover. In many states, pharmacists are also legally permitted to substitute a generic for a brand-name prescription without a new doctor's order, as long as the prescriber hasn't blocked substitution.
A two-minute conversation at the pharmacy counter can save you months of back-and-forth.
Step 3: Ask Your Doctor for a Generic Switch
If your pharmacist confirms a generic exists but says they need a new prescription or your doctor has blocked substitution, your next step is a simple call or patient portal message to your doctor:
"I'd like to switch to the generic version of [drug name] before the tariff takes effect in September. Can you update my prescription?"
Most doctors will approve this without an appointment. It is a medically straightforward request — generics undergo rigorous FDA review and are therapeutically equivalent.
Step 4: Check Your Insurance Formulary
Even if a generic exists and your doctor approves, your insurance may have specific coverage rules. Log into your insurance portal and look up both the brand and generic version of your drug under the formulary tool.
Things to look for:
- Tier placement — Generics are almost always in a lower tier (lower copay) than brand-name drugs
- Prior authorization requirements — Some plans require a step-therapy process before covering generics (rare, but possible)
- Preferred vs. non-preferred — Some formularies have preferred generics with lower copays than non-preferred generics
Step 5: Use GoodRx or Cost Plus Drugs as a Backup
If you are uninsured or your insurance doesn't cover the generic well, check GoodRx and Mark Cuban's Cost Plus Drugs before paying full price. Many generics at Cost Plus Drugs are available for $3–15 per month — a fraction of their brand-name counterparts and a complete bypass of any tariff impact.
What If No Generic Exists?
If there is no FDA-approved generic for your drug:
- Check for biosimilars (if it's a biologic) — these are the biologic equivalent of generics and are also fully exempt
- Check if your manufacturer is an Annex III MFN deal company (see our MFN deal tracker) — if so, your drug pays 0% anyway
- Check the specialty exempt categories — orphan drugs, plasma-derived therapies, fertility treatments, and others are fully exempt

The Bottom Line
Switching to a generic is the most direct, most effective way to eliminate your tariff exposure. With the tariff effective dates months away, you have time to make this transition smoothly — before it becomes urgent. Start with your pharmacist, escalate to your doctor if needed, and use the RxTariff tool to confirm your drug's status every step of the way.
