Frequently asked questions

What does Isopto Cetamide treat?
Isopto Cetamide (Sulfacetamide Sodium) may be used to treat corneal ulcer, ear diseases, seborrheic dermatitis, trachoma, bacterial skin diseases, 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 Isopto Cetamide 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 $0.11 per gm, 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 Isopto Cetamide?
pharmaranks is an independent ratings site, not a pharmacy — we don't issue coupons or sell Isopto Cetamide. To pay less, Isopto Cetamide is already a generic — usually the lowest-cost version — so the main levers are comparing cash prices between pharmacies and using a pharmacy discount-card service. Prices vary by pharmacy, insurance, and location, so always confirm at the counter. This is general reference, not medical or financial advice.
