Frequently asked questions

What does Isoniazid treat?

Isoniazid (Isoniazid) may be used to treat tuberculosis, 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 is Isoniazid rated?

pharmaranks gives Isoniazid a composite score of 3.5 out of 5, currently based on 1 weighted source (FDA regulatory recall-safety data weighted highest). See our methodology at /how-we-rate.

How much does Isoniazid 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 $96.88 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, Ethambutol Hydrochloride — about $13.42 on the same basis.

Is there a coupon or discount for Isoniazid?

pharmaranks is an independent ratings site, not a pharmacy — we don't issue coupons or sell Isoniazid. To pay less, Isoniazid 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.
