Frequently asked questions

What does Quinidine Sulfate treat?

Quinidine Sulfate (Quinidine Sulfate) may be used to treat atrial fibrillation, atrial flutter, based on NIH RxClass drug-classification data (conditions a drug may treat — not a verbatim copy of the FDA-approved label). This is general reference, not medical advice.

How does Quinidine Sulfate work?

Quinidine Sulfate is a antiarrhythmic. Antiarrhythmics steady an irregular heartbeat by controlling the flow of sodium, potassium, or calcium ions through heart-cell channels (or blunting adrenaline's effect), which slows or normalizes the heart's electrical signals so it beats in a more regular rhythm.

How much does Quinidine Sulfate cost?

Nobody can tell you what you will pay — your price is set by your insurer's formulary, your deductible and the pharmacy's markup, and none of those are published. What IS published is what the pharmacy paid to acquire it: about $326.26 for 30, per the CMS NADAC survey. Treat that as the floor, not the quote — ask the pharmacist for the cash price as well as your copay, because for cheap generics the cash price often wins. Pharmacies pay less for a same-class option, Amiodarone Hydrochloride — about $3.68 on the same basis.

Is there a coupon or discount for Quinidine Sulfate?
