Guanfacine ER Coupons 2026 — Or Pay $144 Without One

Yes, Guanfacine ER coupons exist via GoodRx, manufacturer programs, and PAPs — each with its own limits. ScriptUnlock's pharmacy bidding system often beats coupon prices because pharmacies compete for your fill rather than offering a fixed discount. Guanfacine ER cash prices via ScriptUnlock typically start from $144.

Compare live pharmacy cash prices on ScriptUnlock first — that's your true floor. Then check a GoodRx coupon and any manufacturer card. Use whichever number is lowest at pickup. For Guanfacine ER, ScriptUnlock prices commonly land at ~$144 vs $180 retail.

Most chain pharmacies accept major coupons for Guanfacine ER, but they’re not legally required to. Independent pharmacies sometimes can’t process certain coupons. Pharmacy cash bidding via ScriptUnlock sidesteps this — the price is the price, and you pay it directly.

Generally no — you can use either the coupon price or the insurance copay, whichever is lower, but not both for the same fill. Coupons also typically don’t count toward your insurance deductible. Always ask your pharmacist to compare both before paying.

For most fills, yes — particularly on brand-name and specialty medications where pharmacy margins are wider. For very low-cost generics, GoodRx and ScriptUnlock sometimes land at the same price. ScriptUnlock costs nothing to check, so compare every fill.

Without insurance, Guanfacine ER costs between $144 and $234 per 30-day supply depending on the pharmacy. Cash prices vary widely — chain pharmacies typically charge 40–70% more than independent verified pharmacies. Using Script Unlock to compare live pharmacy prices, cash-pay patients typically pay around $144/month.

Each pharmacy sets its own cash price for Guanfacine ER based on wholesale cost, PBM contracts, overhead, and local competition. Large chains often charge significantly more than independents for the same medication. Script Unlock creates real price competition by showing you cash prices from multiple verified pharmacies at once.

Yes. Generic Guanfacine extended-release is FDA-approved and contains the identical active ingredient as brand-name Guanfacine ER. Generics undergo the same bioequivalence testing and are held to identical manufacturing standards. Generic Guanfacine extended-release typically costs 60–90% less than brand Guanfacine ER.

No. Guanfacine ER requires a valid prescription from a licensed prescriber (physician, nurse practitioner, or physician assistant) in the United States. Script Unlock connects you with verified pharmacies once you have a prescription — we cannot prescribe medication.

The cheapest pharmacy for Guanfacine ER depends on your zip code and changes over time as pharmacies adjust prices. In our data, verified independent pharmacies typically offer the lowest cash prices — often 40–70% below chain retail. Costco and Walmart tend to be the cheapest chain options, though verified independents can still undercut them. Script Unlock shows live prices from multiple nearby pharmacies free — no account required.

Coverage for Guanfacine ER depends on your specific insurance plan's formulary. Most commercial insurance and Medicare Part D plans cover generic Guanfacine extended-release. Brand-name Guanfacine ER may require prior authorization or be placed on a higher tier. Even when insurance covers Guanfacine ER, the cash price via Script Unlock is sometimes lower than the insurance copay — always compare both.

GoodRx, SingleCare, and other coupon apps show pre-negotiated PBM prices. Pharmacies still make margin on those prices via PBM contracts. Script Unlock takes a different approach — real-time competition between verified pharmacies where they bid for your prescription. The result: cash prices typically 15–40% below coupon-app prices for the same medication at the same pharmacy chain.

Yes — provided the pharmacy is state-licensed and, ideally, LegitScript or NABP verified. All pharmacies on Script Unlock are US state-licensed and verified against federal exclusion lists. Independent pharmacies are held to the same regulatory standards as chain pharmacies — they simply have lower overhead and pass the savings to you.

Yes. Medicare patients can pay cash for Guanfacine ER instead of using Part D when it's cheaper — and often it is. Cash prices via Script Unlock are frequently lower than Medicare Part D copays, especially in the coverage gap ("donut hole"). Note: cash purchases do not count toward Part D true out-of-pocket (TrOOP) totals, so factor that into your annual planning.

Yes. Pharmacy cash prices can change weekly based on wholesale cost fluctuations, PBM contract renegotiations, and local competition. Script Unlock refreshes verified pharmacy pricing regularly — so the price you see is the price you pay when you fill the prescription.

Mail-order can be convenient for 90-day maintenance supplies, but delivery time (5–10 business days) and shipping fees can offset savings. For urgent or short-term fills, local pharmacies via Script Unlock are typically faster and cost-competitive. Compare both — many patients use local for the first fill and mail-order for refills.

Manufacturer copay cards typically require commercial insurance (they don't work for Medicare, Medicaid, or cash-pay patients), have annual maximum benefits, and expire annually. For many patients, cash prices via Script Unlock are lower than what a copay card would deliver. Always compare cash price to copay-card price before using the card.

Search Guanfacine ER on Script Unlock, choose the pharmacy with the price you want, and either transfer your prescription to that pharmacy or upload it directly. The pharmacy is contractually bound to honor the price shown. No coupon codes, no membership fees, no hidden costs.
