  • Lamivudine treats HIV-1 infection when combined with other HIV medicines. A separate lower-dose tablet treats chronic hepatitis B. Make sure you have the version your doctor prescr...
  • For HIV-1 it is taken by mouth once or twice daily, with or without food. Follow your prescriber's schedule exactly. Children's doses depend on weight.
  • Common ones are headache, nausea, tiredness, stuffy nose, diarrhea and cough. Call your doctor if you notice signs of liver problems, pancreatitis, or an allergic reaction.
  • Please don't stop on your own. If you also have hepatitis B, stopping can cause a serious flare-up, and your liver needs close monitoring afterward. Talk to your doctor first.

This page's concept Lamivudine 300 MG Oral Tablet [Epivir] RxCUI 352230

Showing up to 8 concepts per family — 13 of 14 stored related concepts drawn.
These are official RxNorm vocabulary relationships — how concepts name and organize the same medicine. They do not establish therapeutic equivalence or substitutability: two concepts appearing in one web is never a statement that products can be swapped.

🔀 Generic ⇄ Brand Crosswalk

The same medicine has an unbranded (generic) identity and one or more brand-name identities — each with its own RxCUI. This is a naming relationship in RxNorm, not a statement that any two products are substitutable.

  • A shared RxCUI does not prove interchangeability. Products mapped to the same concept are not thereby equivalent or substitutable — equivalence is a separate, product-level determination.
  • Listing here does not establish approval or coverage. Appearing in this snapshot is a data observation, not an FDA approval status or a payer coverage decision.
  • Missing data never means zero. A silent dataset (no price, no billing code, no utilization) means no observation — not that the real-world value is zero.
  • Counts describe the mapping footprint. Product, package, and labeler counts are the FDA-listed mapping footprint in this snapshot — not sales, inventory, availability, or market share.
This product uses publicly available data from the U.S. National Library of Medicine (NLM), National Institutes of Health, Department of Health and Human Services; NLM is not responsible for the product and does not endorse or recommend this or any other product.
