Frequently asked questions
- What does Nydrazid treat?
- Nydrazid (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 Nydrazid rated?
- pharmaranks gives Nydrazid a composite score of 3.6 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 Nydrazid 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 $13.48 on the same basis.
- Is there a coupon or discount for Nydrazid?
- pharmaranks is an independent ratings site, not a pharmacy — we don't issue coupons or sell Nydrazid. 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.

What people report to the FDA about ISONIAZID
The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 17,284 reports naming ISONIAZID — the active ingredient in Nydrazid, and the FDA flagged 91% of those reports as serious. The effects reported most often — leaving out reports about overdose, misuse or the condition being treated, which dominate the raw list for common medicines:
- pyrexia1,265 reports
- nausea1,046 reports
- drug-induced liver injury884 reports
- drug reaction with eosinophilia and systemic symptoms768 reports
- headache704 reports
- vomiting692 reports
- malaise586 reports
- anaemia582 reports
Read these as a signal, not a rate. A report does not mean ISONIAZID caused the effect — anyone can file one, and many describe people taking several medicines for several conditions. Crucially there is no denominator: FAERS does not record how many people took the drug, so these counts cannot be turned into “X% of patients” — a bigger number often just means a more widely used or more talked-about drug. Duplicates exist, and publicity drives reporting. For what is actually established, read the FDA label.
