Frequently asked questions
- What does Epivir treat?
- Epivir (Lamivudine) may be used to treat acquired immunodeficiency syndrome, 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 Epivir 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 $0.44 per ml, 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 Epivir?
- pharmaranks is an independent ratings site, not a pharmacy — we don't issue coupons or sell Epivir. 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 LAMIVUDINE
The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 35,106 reports naming LAMIVUDINE — the active ingredient in Epivir, and the FDA flagged 96% 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:
- foetal exposure during pregnancy2,760 reports
- virologic failure2,439 reports
- pathogen resistance2,236 reports
- drug resistance2,190 reports
- viral mutation identified2,090 reports
- exposure during pregnancy1,645 reports
- pyrexia1,508 reports
- treatment failure1,320 reports
Read these as a signal, not a rate. A report does not mean LAMIVUDINE 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.
