Frequently asked questions

What does Imuran treat?
Imuran (Azathioprine Sodium) may be used to treat rheumatoid arthritis, ulcerative colitis, crohn disease, systemic lupus erythematosus, multiple sclerosis, idiopathic thrombocytopenic purpura, 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 much does Imuran 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 $3.97 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.
Is there a coupon or discount for Imuran?
pharmaranks is an independent ratings site, not a pharmacy — we don't issue coupons or sell Imuran. To pay less, ask your prescriber or pharmacist whether a generic equivalent exists, check the manufacturer's copay/savings card and patient-assistance program, and compare a pharmacy discount card against your insurance copay. Prices vary by pharmacy, insurance, and location, so always confirm at the counter. This is general reference, not medical or financial advice.
