📖 What it is MedlinePlus · NLM

Lamivudine is used to treat human immunodeficiency virus (HIV) infection. Lamivudine is in a class of medications called nucleoside reverse transcriptase inhibitors (NRTIs). It works by decreasing the amount of HIV in the blood. Although lamivudine will not cure HIV, it may decrease your chance of developing acquired immunodeficiency syndrome (AIDS) and HIV-related illnesses. Taking these medications and making other lifestyle changes may also decrease the risk of giving the HIV virus to other people.

  • 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.

Pricing

A drug doesn't have one price. Each row is a different public payment system, and none is what you'd pay at the counter — that depends on your insurance. The ⓘ on each row explains what it measures.

Where does this data come from?
NADAC (National Average Drug Acquisition Cost) is the CMS weekly pharmacy-acquisition-cost survey — what pharmacies pay. ASP (Average Sales Price) is the CMS Medicare Part B drug-payment file, published quarterly. Medicaid pays is computed by us from CMS State Drug Utilization Data (total reimbursed ÷ units, trailing 12 months) — gross of rebates and inclusive of dispensing fees, so it reflects what Medicaid paid, not an acquisition cost. Medicare drug plans pay is the median negotiated point-of-sale unit cost across plans listing this NDC in the CMS quarterly Prescription Drug Plan pricing files, before rebates. The VA pays is the federal contract price (FSS, and the statutory Big 4 ceiling where listed) from the VA National Acquisition Center pharmaceutical price file. All are free public government data; each measures a different payer, so the figures are not directly comparable.

⚠️ Warnings and Cautions ~2 min read ▾

5 WARNINGS AND PRECAUTIONS Co-infected HIV-1/HBV Patients: Emergence of lamivudineresistant HBV variants associated with lamivudine-containing antiretroviral regimens has been reported. (5.2) Hepatic decompensation, some fatal, has occurred in HIV-1/HCV co-infected patients receiving interferon and ribavirin-based regimens. Monitor for treatment-associated toxicities.

Discontinue LAMIVUDINE as medically appropriate and consider dose reduction or discontinuation of interferon alfa, ribavirin, or both. (5.3) Pancreatitis: Use with caution in pediatric patients with a history of pancreatitis or other significant risk factors for pancreatitis. Discontinue treatment as clinically appropriate.

(5.4) Immune reconstitution syndrome and redistribution/accumulation of body fat have been reported in patients treated with combination antiretroviral therapy. (5.5, 5.7) Lower virologic suppression rates and increased risk of viral resistance were observed in pediatric subjects who received LAMIVUDINE oral solution concomitantly with other antiretroviral oral solutions compared with those who received tablets. (5.6)

5.1Lactic Acidosis and Severe Hepatomegaly with Steatosis Lactic acidosis and severe hepatomegaly with steatosis, including fatal cases, have been reported with the use of nucleoside analogues and other antiretrovirals. A majority of these cases have been in women. Obesity and prolonged nucleoside exposure may be risk factors.

Caution should be exercised when administering LAMIVUDINE to any patient with known risk factors for liver disease; however, cases also have been reported in patients with no known risk factors. Treatment with LAMIVUDINE should be suspended in any patient who develops clinical or laboratory findings suggestive of lactic acidosis or pronounced hepatotoxicity (which may include hepatomegaly and steatosis even in the absence of marked transaminase elevations).

5.2Patients with and Hepatitis B Virus Co-infection Posttreatment Exacerbations of Hepatitis Clinical and laboratory evidence of exacerbations of hepatitis have occurred after discontinuation of lamivudine. These exacerbations have been detected primarily by serum ALT elevations in addition to re-emergence of HBV DNA. Although most events appear to have been self-limited, fatalities have been reported in some cases.

Similar events have been reported from postmarketing experience after changes from lamivudine-containing HIV-1 treatment regimens to non-lamivudine-containing regimens in patients infected with both HIV-1 and HBV. The causal relationship to discontinuation of lamivudine treatment is unknown. Patients should be closely monitored with both clinical and laboratory follow-up for at least several months after stopping treatment.

Important Differences among Lamivudine-containing Products LAMIVUDINE tablets contain a higher dose of the same active ingredient (lamivudine) than LAMIVUDINE-HBV tablets. LAMIVUDINE-HBV was developed for patients with chronic hepatitis B. The formulation and dosage of lamivudine in LAMIVUDINE-HBV are not appropriate for patients co-infected with HIV-1 and HBV.

Safety and efficacy of lamivudine have not been established for treatment of chronic hepatitis B in patients co-infected with HIV-1 and HBV. If treatment with LAMIVUDINE-HBV is prescribed for chronic hepatitis B for a patient with unrecognized or untreated HIV-1 infection, rapid emergence of HIV-1 resistance is likely to result because of the subtherapeutic dose and the inappropriateness of monotherapy HIV-1 treatment. If a decision is made to administer lamivudine to patients co-infected with HIV-1 and HBV, LAMIVUDINE tablets, or another product containing the higher dose of lamivudine should be used as part of an appropriate combination regimen.

Emergence of Lamivudine-resistant HBV Safety and efficacy of lamivudine have not been established for treatment of chronic hepatitis B in subjects dually infected with HIV-1 and HBV (see full prescribing information for… [Excerpted — this section continues on DailyMed.]

🔄 Drug Interactions 69 words ▾

7 DRUG INTERACTIONS Lamivudine is predominantly eliminated in the urine by active organic cationic secretion. The possibility of interactions with other drugs administered concurrently should be considered, particularly when their main route of elimination is active renal secretion via the organic cationic transport system (e.g., trimethoprim) [see Pharmacokinetics (12.3) ]. No data are available regarding interactions with other drugs that have renal clearance mechanisms similar to that of lamivudine.

8 USE IN SPECIFIC POPULATIONS Lactation: Breastfeeding not recommended. (8.2) Additional pediatric use information for patients aged 3 months and above is approved for ViiV Healthcare Company’s EPIVIR ® (lamivudine) tablets and oral solution. However, due to ViiV Healthcare Company’s marketing exclusivity rights, this drug product is not labeled with that pediatric information.

8.1Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to LAMIVUDINE during pregnancy. Physicians are encouraged to register patients by calling the Antiretroviral Pregnancy Registry at 1-800-258-4263. Risk Summary Available data from the Antiretroviral Pregnancy Registry show no difference in the risk of overall major birth defects for lamivudine compared with the background rate for major birth defects of 2.7% in the US reference population of the Metropolitan Atlanta Congenital Defects Program (MACDP).

Lamivudine produced embryonic toxicity in rabbits at a dose that produced similar human exposures as the recommended clinical dose. The relevance of animal findings to human pregnancy registry data is not known. Data Human Data: Based on prospective reports from the Antiretroviral Pregnancy Registry of over 11,000 exposures to lamivudine during pregnancy resulting in live births (including over 4,300 exposed in the first trimester), there was no difference between lamivudine and overall birth defects compared with the background birth defect rate of 2.7% in the US reference population of the MACDP.

The prevalence of defects in the first trimester was 3.1% (95% CI: 2.6% to 3.7%). Lamivudine pharmacokinetics were studied in pregnant women during 2 clinical trials conducted in South Africa. The trials assessed pharmacokinetics in 16 women at 36 weeks gestation using 150 mg lamivudine twice daily with zidovudine, 10 women at 38 weeks gestation using 150 mg lamivudine twice daily with zidovudine, and 10 women at 38 weeks gestation using lamivudine 300 mg twice daily without other antiretrovirals.

These trials were not designed or powered to provide efficacy information. Lamivudine pharmacokinetics in pregnant women were similar to those seen in non-pregnant adults and in postpartum women. Lamivudine concentrations were generally similar in maternal, neonatal, and umbilical cord serum samples.

In a subset of subjects, amniotic fluid specimens were collected following natural rupture of membranes and confirmed that lamivudine crosses the placenta in humans. Amniotic fluid concentrations of lamivudine were typically 2 times greater than maternal serum levels and ranged from 1.2 to 2.5 mcg per mL (150 mg twice daily) and 2.1 to 5.2 mcg per mL (300 mg twice daily). Animal Data: Studies in pregnant rats showed that lamivudine is transferred to the fetus through the placenta.

Reproduction studies with orally administered lamivudine have been performed in rats and rabbits at doses producing plasma levels up to approximately 35 times that for the recommended adult HIV dose. No evidence of teratogenicity due to lamivudine was observed. Evidence of early embryolethality was seen in the rabbit at exposure levels similar to those observed in humans but there was no indication of this effect in the rat at exposure levels up to 35 times those in humans.

8.2Lactation Risk Summary The Centers for Disease Control and Prevention recommend that HIV-1-infected mothers in the United States not breastfeed their infants to avoid risking postnatal transmission of HIV-1 infection. Because of the potential for HIV-1 transmission mothers should be instructed not to breastfeed.

8.4Pediatric Use The safety and effectiveness of LAMIVUDINE in combination with other antiretroviral agents have been established in pediatric patients aged 3 months and older. LAMIVUDINE scored tablet is the preferred formulation for HIV-1-infected pediatric patients who weigh at least 14 kg and for whom a solid dosage form is appropr… [Excerpted — this section continues on DailyMed.]

8.4Pediatric Use The safety and effectiveness of LAMIVUDINE in combination with other antiretroviral agents have been established in pediatric patients aged 3 months and older. LAMIVUDINE scored tablet is the preferred formulation for HIV-1-infected pediatric patients who weigh at least 14 kg and for whom a solid dosage form is appropriate because pediatric subjects who received LAMIVUDINE oral solution had lower rates of virologic suppression, lower plasma lamivudine exposure, and developed viral resistance more frequently than those receiving LAMIVUDINE tablets in the ARROW trial [see Dosage and Administration (2.2) , Warnings and Precautions (5.6) , Adverse Reactions (6.1) , Clinical Pharmacology (12.3) , Clinical Studies (14.2) ].

🧓 Geriatric Use 68 words ▾

8.5Geriatric Use Clinical trials of LAMIVUDINE did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects.In general, caution should be exercised in the administration of LAMIVUDINE in elderly patients reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease orother drug therapy [see Dosage and Administration (2.3) , Clinical Pharmacology (12.3) ].

🆘 Overdosage 62 words ▾

10 OVERDOSAGE There is no known specific treatment for overdose with LAMIVUDINE. If overdose occurs, the patient should be monitored and standard supportive treatment applied as required. Because a negligible amount of lamivudine was removed via (4-hour) hemodialysis, continuous ambulatory peritoneal dialysis, and automated peritoneal dialysis, it is not known if continuous hemodialysis would provide clinical benefit in a lamivudine overdose event.

12.3Pharmacokinetics Pharmacokinetics in Adults The pharmacokinetic properties of lamivudine have been studied in asymptomatic, HIV-1-infected adult subjects after administration of single intravenous (IV) doses ranging from 0.25 to 8 mg per kg, as well as single and multiple (twice-daily regimen) oral doses ranging from 0.25 to 10 mg per kg. The pharmacokinetic properties of lamivudine have also been studied as single and multiple oral doses ranging from 5 mg to 600 mg per day administered to HBV-infected subjects.

The steady-state pharmacokinetic properties of the LAMIVUDINE 300-mg tablet once daily for 7 days compared with the LAMIVUDINE 150-mg tablet twice daily for 7 days were assessed in a crossover trial in 60 healthy subjects. LAMIVUDINE 300 mg once daily resulted in lamivudine exposures that were similar to LAMIVUDINE 150 mg twice daily with respect to plasma AUC 24,ss ; however, C max,ss was 66% higher and the trough value was 53% lower compared with the 150-mg twice-daily regimen. Intracellular lamivudine triphosphate exposures in peripheral blood mononuclear cells were also similar with respect to AUC 24,ss and C max24,ss ; however, trough values were lower compared with the 150-mg twice-daily regimen.

Inter-subject variability was greater for intracellular lamivudine triphosphate concentrations versus lamivudine plasma trough concentrations. The pharmacokinetics of lamivudine was evaluated in 12 adult HIV-1-infected subjects dosed with lamivudine 150 mg twice daily in combination with other antiretroviral agents. The geometric mean (95% CI) for AUC (0-12) was 5.53 (4.58, 6.67) mcg.h per mL and for C max was 1.40 (1.17, 1.69) mcg per mL.

Absorption and Bioavailability: Following oral administration, lamivudine is rapidly absorbed and extensively distributed.Absolute bioavailability in 12 adult subjects was 86% ± 16% (mean ± SD) for the 150-mg tablet. After oral administration of 2 mg per kg twice a day to 9 adults with HIV-1, the peak serum lamivudine concentration (C max ) was 1.5 ± 0.5 mcg per mL (mean ± SD). The area under the plasma concentration versus time curve (AUC) and C max increased in proportion to oral dose over the range from 0.25 to 10 mg per kg.

The accumulation ratio of lamivudine in HIV-1-positive asymptomatic adults with normal renal function was 1.50 following 15 days of oral administration of 2 mg per kg twice daily. Effects of Food on Oral Absorption: LAMIVUDINE tablets may be administered with or without food. An investigational 25-mg dosage form of lamivudine was administered orally to 12 asymptomatic, HIV-1-infected subjects on 2 occasions, once in the fasted state and once with food (1,099 kcal; 75 grams fat, 34 grams protein, 72 grams carbohydrate).

Absorption of lamivudine was slower in the fed state (T max : 3.2 ± 1.3 hours) compared with the fasted state (T max : 0.9 ± 0.3 hours); C max in the fed state was 40% ± 23% (mean ± SD) lower than in the fasted state. There was no significant difference in systemic exposure (AUC∞) in the fed and fasted states. Distribution: The apparent volume of distribution after IV administration of lamivudine to 20 subjects was 1.3 ±

0.4L per kg, suggesting that lamivudine distributes into extravascular spaces. Volume of distribution was independent of dose and did not correlate with body weight. Binding of lamivudine to human plasma proteins is low (less than 36%).

In vitro studies showed that over the concentration range of 0.1 to 100 mcg per mL, the amount of lamivudine associated with erythrocytes ranged from 53% to 57% and was independent of concentration. Metabolism: Metabolism of lamivudine is a minor route of elimination. In humans, the only known metabolite of lamivudine is the trans-sulfoxide metabolite(approximately 5% of an oraldose after 12 hours).

💬 Information for Patients ~2 min read ▾

17 PATIENT COUNSELING INFORMATION Advise the patient to read the FDA-approved patient labeling (Patient Information). Lactic Acidosis/Hepatomegaly Inform patients that some HIV medicines, including LAMIVUDINE, can cause a rare, but serious condition called lactic acidosis with liver enlargement (hepatomegaly) [see Warnings and Precautions (5.1) ]. Patients with Hepatitis B or C Co-infection Inform patients co-infected with HIV-1 and HBV should be informed that deterioration of liver disease has occurred in some cases when treatment with lamivudine was discontinued.

Advise patients to discuss any changes in regimen with their physician [see Warnings and Precautions (5.2) ]. Inform patients with HIV-1/HCV co-infection that hepatic decompensation (some fatal) has occurred in HIV-1/HCV co-infected patients receiving combination antiretroviral therapy for HIV-1 and interferon alfa with or without ribavirin [see Warnings and Precautions (5.3) ]. Differences in Formulations of LAMIVUDINE Advise patients that LAMIVUDINE Tablets and contain a higher dose of the same active ingredient (lamivudine) as LAMIVUDINE-HBV Tablets.

If a decision is made to include lamivudine Tablets in the HIV-1 treatment regimen of a patient co-infected with HIV-1 and HBV, the formulation and dosage of lamivudine in LAMIVUDINE (not LAMIVUDINE-HBV) should be used [see Warnings and Precautions (5.2) ]. Risk of Pancreatitis Advise parents or guardians to monitor pediatric patients for signs and symptoms of pancreatitis [see Warnings and Precautions (5.4) ]. Immune Reconstitution Syndrome In some patients with advanced HIV infection, signs and symptoms of inflammation from previous infections may occur soon after anti-HIV treatment is started.

It is believed that these symptoms are due to an improvement in the body's immune response, enabling the body to fight infections that may have been present with no obvious symptoms. Advise patients to inform their healthcare provider immediately of any symptoms of infection [see Warnings and Precautions (5.5) ]. Redistribution/Accumulation of Body Fat Inform patients that redistribution or accumulation of body fat may occur in patients receiving antiretroviral therapy, including LAMIVUDINE, and that the cause and long-term health effects of these conditions are not known at this time [see Warnings and Precautions (5.7) ].

Pregnancy Registry Advise patients that there is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to LAMIVUDINE during pregnancy [see Use in Specific Populations (8.1) ]. Lactation Instruct women with HIV-1 infection not to breastfeed because HIV-1 can be passed to the baby in the breast milk [see Use in Specific Populations (8.2) ]. Missed Dosage Instruct patients that if they miss a dose of LAMIVUDINE, to take it as soon as they remember.

Advise patients not to double their next dose or take more than the prescribed dose [see Dosage and Administration (2) ].

🔬 Clinical Studies ~3 min read ▾

14 CLINICAL STUDIES The use of LAMIVUDINE is based on the results of clinical trials in HIV-1-infected subjects in combination regimens with other antiretroviral agents. Information from trials with clinical endpoints or a combination of CD4+ cell counts and HIV-1 RNA measurements is included below as documentation of the contribution of lamivudine to a combination regimen in controlled trials.

14.1Adult Subjects Clinical Endpoint Trial: NUCB3007 (CAESAR) was a multi-center, double-blind, placebo-controlled trial comparing continued current therapy (zidovudine alone [62% of subjects] or zidovudine with didanosine or zalcitabine [38% of subjects]) to the addition of LAMIVUDINE or LAMIVUDINE plus an investigational non-nucleoside reverse transcriptase inhibitor (NNRTI), randomized 1:2:1. A total of 1,816 HIV-1-infected adults with 25 to 250 CD4+ cells per mm3 (median = 122 cells per mm3) at baseline were enrolled: median age was 36 years, 87% were male, 84% were nucleoside-experienced, and 16% were therapy-naive.

The median duration on trial was 12 months. Results are summarized in Table 9. Table 9.

Number of Subjects (%) with at Least One HIV-1 Disease Progression Event or Death Endpoint Current Therapy (n = 460) LAMIVUDINE plus Current Therapy (n = 896) LAMIVUDINE plus an NNRTI An investigational non-nucleoside reverse transcriptase inhibitor not approved in the United States.Achieved confirmed plasma HIV-1 RNA less than 400 copies/mL and maintained through 48 weeks.Achieved suppression but rebounded by Week 48, discontinued due to virologic failure, insufficient viral response according to the investigator, or never suppressed through Week 48.Includes consent withdrawn, lost to follow-up, protocol violation, data outside the trial-defined schedule, and randomized but never initiated treatment.Roche AMPLICOR HIV-1 MONITOR.Responders at each visit are subjects who had achieved and maintained HIV-1 RNA less than 400 copies per mL without discontinuation by that visit. plus Current Therapy (n = 460) HIV-1 progression or death 90 (19.6%) 86 (9.6%) 41 (8.9%) Death 27 (5.9%) 23 (2.6%) 14 (3.0%) Surrogate Endpoint Trials Dual Nucleoside Analogue Trials: Principal clinical trials in the initial development of lamivudine compared lamivudine/zidovudine combinations with zidovudine monotherapy or with zidovudine plus zalcitabine.

These trials demonstrated the antiviral effect of lamivudine in a 2-drug combination. More recent uses of lamivudine in treatment of HIV-1 infection incorporate it into multiple-drug regimens containing at least 3 antiretroviral drugs for enhanced viral suppression. Dose Regimen Comparison Surrogate Endpoint Trials in Therapy-naive Adults: EPV20001 was a multi-center, double-blind, controlled trial in which subjects were randomized 1:1 to receive LAMIVUDINE 300 mg once daily or LAMIVUDINE 150 mg twice daily, in combination with zidovudine 300 mg twice daily and efavirenz 600 mg once daily.

A total of 554 antiretroviral treatment-naive HIV-1-infected adults enrolled: male (79%), white (50%), median age of 35 years, baseline CD4+ cell counts of 69 to 1,089 cells per mm 3 (median = 362 cells per mm 3 ), and median baseline plasma HIV-1 RNA of 4.66 log 10 copies per mL.

13 NONCLINICAL TOXICOLOGY

13.1Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenesis Long-term carcinogenicity studies with lamivudine in mice and rats showed no evidence of carcinogenic potential at exposures up to 10 times (mice) and 58 times (rats) the human exposures at the recommended dose of 300 mg. Mutagenesis Lamivudine was mutagenic in an L5178Y mouse lymphoma assay and clastogenic in a cytogenetic assay using cultured human lymphocytes. Lamivudine was not mutagenic in a microbial mutagenicity assay, in an in vitro cell transformation assay, in a rat micronucleus test, in a rat bone marrow cytogenetic assay, and in an assay for unscheduled DNA synthesis in rat liver.

Lamivudine showed no evidence of in vivo genotoxic activity in the rat at oral doses of up to 2,000 mg per kg, producing plasma levels of 35 to 45 times those in humans at the recommended dose for HIV-1 infection. Impairment of Fertility In a study of reproductive performance, lamivudine administered to rats at doses up to 4,000 mg per kg per day, producing plasma levels 47 to 70 times those in humans, revealed no evidence of impaired fertility and no effect on the survival, growth, and development to weaning of the offspring.

Lamivudine showed no evidence of in vivo genotoxic activity in the rat at oral doses of up to 2,000 mg per kg, producing plasma levels of 35 to 45 times those in humans at the recommended dose for HIV-1 infection. Impairment of Fertility In a study of reproductive performance, lamivudine administered to rats at doses up to 4,000 mg per kg per day, producing plasma levels 47 to 70 times those in humans, revealed no evidence of impaired fertility and no effect on the survival, growth, and development to weaning of the offspring.

Medicare Part D spend CMS · PART D · 2026 (Q1)

Medicare Part D (outpatient prescription) spending for Lamivudine — the program that covers self-administered drugs. 6 manufacturers.
⚠️ Drug-level data: CMS publishes Part D spending by drug, not by NDC — these figures combine every manufacturer, strength and package size sold under the name Lamivudine. That’s a different level of aggregation than the Medicaid card above, which is specific to this exact 11-digit NDC (pack size included), so the two aren’t directly comparable.

💵 About the dollar figures: spending is what Part D plans paid before confidential manufacturer rebates, so the program’s real net cost is lower. A blank patient count means fewer than 11 people — CMS hides counts that small to protect privacy. Source: CMS Medicare Quarterly Part D Spending by Drug (data.cms.gov), updated quarterly.

Questions about this listing

Why is there no price listed?
The pricing shown on our NDC pages comes from CMS NADAC, a voluntary survey of retail community pharmacy invoices. CMS does not publish a NADAC for every NDC — packages outside the retail survey (institutional and hospital products, bulk packages, discontinued items, and many OTC items) may never receive one. A missing price reflects the survey's scope, not this product's actual cost, and does not mean the product is free or unavailable.
Is the NDC printed on the package the same as the 11-digit billing NDC?
Yes, they identify this exact package in different formats. The form printed on the packaging and shown on DailyMed is the one the FDA registered. Insurance claims use a fixed 11-digit 5-4-2 format, so the short segment is padded with a leading zero and the dashes are dropped. The Identity section at the top of this page lists each form of this code.
Is this package still being marketed?
Yes, per the latest FDA NDC Directory data on this page: this package is listed as actively marketed, with no marketing end date reported by Ingenus Pharmaceuticals, LLC. Listing status can change — the directory data on this page refreshes weekly.
Who lists this product with the FDA?
