Why two NDCs? The FDA registers this code as 31722-001-60 — a 5-3-2 layout, and that's what's printed on the package and shown on DailyMed. For insurance claims, every NDC is standardized to a uniform 11-digit 5-4-2 format by adding a zero to the product segment → 31722-0001-60. Same drug, same package — only the format differs.

7 inactive ingredients listed in the exact product block matched to this NDC.

Where does this data come from?
Data sourced from official FDA Structured Product Labeling (SPL) via DailyMed — ingredient classCode="IACT" elements from the exact product block matched by this NDC. Label-section narrative from DailyMed / the openFDA label index is shown separately when available.

Inactive ingredient FAQ

Are inactive ingredients the same for every manufacturer?
No. Inactive ingredients can differ by manufacturer, dosage form, strength, and package / product version.
Why might an inactive ingredient be missing?
Some SPLs do not provide a complete structured inactive-ingredient list, and older or unusual labels may only include the information in narrative text.
Can inactive ingredients matter?
Yes. They can matter for allergies, intolerances, dyes, gluten / lactose concerns, preservatives, and formulation differences — but confirm with a pharmacist or the manufacturer when it’s clinically important.

💲 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.

Price systemPer eachPer package
Retail pharmacies payNADAC · weekly Not in the retail survey — common for institutional, discontinued, or low-volume packs.

Medicare drug plans payPart D · Q2 2026 $9.11 $546.63 / 60 tablets
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.

📊 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.

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 FDA registers it as 31722-001-60, which is what is printed on the packaging and shown on DailyMed. Insurance claims use a fixed 11-digit 5-4-2 format, so the short segment is padded with a leading zero: 31722-0001-60, written without dashes as 31722000160. The Identity section at the top of this page lists every form of this code.
What do the three segments of this NDC mean?
In 31722-0001-60, the first segment (31722) is the labeler code FDA assigned to Camber Pharmaceuticals, Inc.; the middle segment (0001) identifies this specific product — its ingredient, strength, and dosage form; and the last segment (60) identifies this exact package size and type. Together they name one specific package of one specific product.
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 Camber Pharmaceuticals, Inc.. Listing status can change — the directory data on this page refreshes weekly.
Does this product come in other package sizes?
Yes — the FDA directory lists 1 other package presentation of this same product, including 10 tablets (31722-0001-02). Each has its own NDC and its own page — see the package list near the top of this page.

WARNING: EXACERBATIONS OF HEPATITIS B and RISK OF HIV-1 RESISTANCE IF LAMIVUDINE TABLETS (HBV) ARE USED IN PATIENTS WITH UNRECOGNIZED OR UNTREATED HIV-1 INFECTION Severe acute exacerbations of hepatitis B have been reported in patients who have discontinued anti-hepatitis B therapy (including lamivudine tablets (HBV)). Hepatic function should be monitored closely with both clinical and laboratory follow-up for at least several months in patients who discontinue anti-hepatitis B therapy. If appropriate, initiation of anti-hepatitis B therapy may be warranted [see Warnings and Precautions ( 5.1 )].

Lamivudine tablets (HBV) are not approved for the treatment of HIV-1 infection because the lamivudine dosage in lamivudine tablets (HBV) is subtherapeutic and monotherapy is inappropriate for the treatment of HIV-1 infection. HIV-1 resistance may emerge in chronic hepatitis B-infected patients with unrecognized or untreated HIV-1 infection. HIV counseling and testing should be offered to all patients before beginning treatment with lamivudine tablets (HBV ) and periodically during treatment [see Warnings and Precautions ( 5.2 )].

WARNING: EXACERBATIONS OF HEPATITIS B and RISK OF HIV-1 RESISTANCE IF LAMIVUDINE TABLETS (HBV) ARE USED IN PATIENTS WITH UNRECOGNIZED OR UNTREATED HIV-1 INFECTION See full prescribing information for complete boxed warning • Severe acute exacerbations of hepatitis B have been reported in patients who have discontinued anti-hepatitis B therapy (including lamivudine tablets (HBV)). Monitor hepatic function closely in these patients and, if appropriate, initiate anti-hepatitis B treatment. ( 5.1 ) • Lamivudine tablets (HBV) contain a lower dose of the same active ingredient (lamivudine) as lamivudine tablets and oral solution used to treat HIV-1 infection.

HIV-1 resistance may emerge in chronic hepatitis B patients with unrecognized or untreated HIV­1 infection because the lamivudine dosage in lamivudine tablets (HBV) is subtherapeutic and monotherapy is inappropriate for the treatment of HIV-1 infection. HIV counseling and testing should be offered to all patients before beginning treatment with lamivudine tablets (HBV) and periodically during treatment. ( 5.2 )

🎯 Indications and Usage 175 words ▾

1 INDICATIONS & USAGE Lamivudine tablets (HBV) are indicated for the treatment of chronic hepatitis B virus (HBV) infection associated with evidence of hepatitis B viral replication and active liver inflammation [see Clinical Studies ( 14.1 , 14.2 )]. The following points should be considered when initiating therapy with lamivudine tablets (HBV): • Due to high rates of resistance development in treated patients, initiation of treatment with lamivudine tablets (HBV) should only be considered when the use of an alternative antiviral agent with a higher genetic barrier to resistance is not available or appropriate. • Lamivudine tablets (HBV) have not been evaluated in patients co-infected with HIV, hepatitis C virus (HCV), or hepatitis delta virus. • Lamivudine tablets (HBV) have not been evaluated in liver transplant recipients or in patients with chronic hepatitis B virus infection with decompensated liver disease.

Lamivudine tablets (HBV) are a nucleoside analogue reverse transcriptase inhibitor indicated for the treatment of chronic hepatitis B virus infection associated with evidence of hepatitis B viral replication and active liver inflammation. ( 1 )

⏱️ Dosage and Administration ~3 min read ▾

2 DOSAGE & ADMINISTRATION • Adults: 100 mg, once daily. ( 2.2 ) • Pediatric Patients aged 2 to 17 years: 3 mg per kg once daily up to 100 mg once daily. Prescribe oral solution for pediatric patients requiring less than 100 mg daily.

( 2.3 ) • Patients with Renal Impairment: Doses of lamivudine tablets (HBV) must be adjusted in accordance with renal function. ( 2.4 ) • Lamivudine tablets (HBV) should not be used with other medications that contain lamivudine or emtricitabine. ( 2.5 )

2.1HIV Counseling and Testing HIV counseling and testing should be offered to all patients before beginning treatment with lamivudine tablets (HBV) and periodically during treatment because of the risk of emergence of resistant HIV-1 and limitation of treatment options if lamivudine tablets (HBV) is prescribed to treat chronic hepatitis B infection in a patient who has unrecognized HIV-1 infection or acquires HIV-1 infection during treatment [see Warnings and Precautions ( 5.2 )].

2.2Recommended Dosage for Adult Patients The recommended oral dosage of lamivudine tablets (HBV) is 100 mg once daily.

2.3Recommended Dosage for Pediatric Patients The recommended oral dosage of lamivudine tablets (HBV) for pediatric patients aged 2 to 17 years is 3 mg per kg once daily up to a maximum daily dosage of 100 mg. The oral solution formulation should be prescribed for patients requiring a dosage less than 100 mg or if unable to swallow tablets.

2.4Patients with Renal Impairment Dosage recommendations for adult patients with reduced renal function are provided in Table 1 [see Clinical Pharmacology ( 12.3 )]. Table 1. Dosage of Lamivudine Tablets (HBV) in Adult Patients with Renal Impairment Cre atinine Clearance ( m L/min) Rec o mme nded Dosage of Lamivudine Tablets (HBV) ≥50 30-49 15-29 5-14 <5 100 mg once daily 100 mg first dose, then 50 mg once daily 100 mg first dose, then 25 mg once daily 35 mg first dose, then 15 mg once daily 35 mg first dose, then 10 mg once daily Following correction of the dosage for renal impairment, no additional dosage modification of lamivudine tablets (HBV) is required after routine (4-hour) hemodialysis or peritoneal dialysis [see Clinical Pharmacology ( 12.3 )].

There are insufficient data to recommend a specific dosage of lamivudine tablets (HBV) in pediatric patients with renal impairment.

2.5Important Administration Instructions • Lamivudine tablets (HBV) may be administered with or without food. • The tablets and oral solution may be used interchangeably [see Clinical Pharmacology ( 12.3 )]. • The oral solution should be used for doses less than 100 mg. • Lamivudine tablets (HBV) should not be used with other medications that contain lamivudine or medications that contain emtricitabine.

2.6Assessing Patients during Treatment Patients should be monitored regularly during treatment by a physician experienced in the management of chronic hepatitis B. During treatment, combinations of events such as return of persistently elevated ALT, increasing levels of HBV DNA over time after an initial decline below assay limit, progression of clinical signs or symptoms of hepatic disease, and/or worsening of hepatic necroinflammatory findings may be considered as potentially reflecting loss of therapeutic response.

Such observations should be taken into consideration when determining the advisability of continuing therapy with lamivudine tablets (HBV). The optimal duration of treatment, the durability of HBeAg seroconversions occurring during treatment, and the relationship between treatment response and long-term outcomes such as hepatocellular carcinoma or decompensated cirrhosis are not known.

⚠️ Warnings and Cautions ~3 min read ▾

5 WARNINGS AND PRECAUTIONS • Emergence of Resistance-Associated HBV Substitutions: Consider a switch to an alternative regimen if serum HBV DNA remains detectable after 24 weeks of treatment. ( 2.6 , 5.3 ) • Lactic acidosis and severe hepatomegaly with steatosis, including fatal cases, have been reported with the use of nucleoside analogues. ( 5.4 )

5.1Exacerbations of Hepatitis after Discontinuation of Treatment 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 commonly observed after stopping treatment; see Table 4 for more information regarding frequency of posttreatment ALT elevations [see Adverse Reactions ( 6.1 )]. Although most events appear to have been self-limited, fatalities have been reported in some cases.

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 with lamivudine tablets (HBV). There is insufficient evidence to determine whether re-initiation of lamivudine tablets (HBV) alters the course of posttreatment exacerbations of hepatitis.

5.2Risk of HIV-1 Resistance if Lamivudine Tablets (HBV) is Used in Patients with Unrecognized or Untreated HIV-1 Infection Lamivudine tablets (HBV) contain a lower lamivudine dose than the lamivudine dose used to treat HIV-1 infection with lamivudine tablets and oral solution or with lamivudine-containing antiretroviral fixed-dose combination products. Lamivudine tablets (HBV) is not appropriate for patients co-infected with HBV and HIV-1. If a patient with unrecognized or untreated HIV-1 infection is prescribed lamivudine tablets (HBV) for the treatment of HBV, rapid emergence of HIV-1 resistance is likely to result because of the subtherapeutic dose and the inappropriate use of monotherapy for HIV-1 treatment.

HIV counseling and testing should be offered to all patients before beginning treatment with lamivudine tablets (HBV) and periodically during treatment because of the risk of rapid emergence of resistant HIV-1 and limitation of treatment options if lamivudine tablets (HBV) is prescribed to treat chronic hepatitis B in a patient who has unrecognized or untreated HIV-1 infection or who acquires HIV-1 infection during treatment.

5.3Emergence of Resistance-Associated HBV Substitutions In controlled clinical trials, YMDD-mutant HBV was detected in subjects with on– lamivudine tablets (HBV) re-appearance of HBV DNA after an initial decline below the assay limit [see Microbiology (12.4)]. Subjects treated with lamivudine tablets (HBV) (adults and children) with YMDD-mutant HBV at 52 weeks showed diminished treatment responses in comparison with subjects treated with lamivudine tablets (HBV) without evidence of YMDD substitutions, including the following: lower rates of HBeAg seroconversion and HBeAg loss (no greater than placebo recipients), more frequent return of positive HBV DNA, and more frequent ALT elevations.

In the controlled trials, when subjects developed YMDD-mutant HBV, they had a rise in HBV DNA and ALT from their previous on-treatment levels. Progression of hepatitis B, including death, has been reported in some subjects with YMDD-mutant HBV, including subjects from the liver transplant setting and from other clinical trials. In orderto reduce the risk of resistance in patients receiving monotherapy with lamivudine tablets (HBV), a switch to an alternative regimen should be considered if serum HBV DNA remains detectable after 24 weeks of treatment.

Optimaltherapy should be guided by resistance testing.

5.4Lactic Acidosis and Severe Hepatomegaly with Steatosis Lactic acidosis and severe hepatomegaly with steatosis, including fatal cases, havebeen reported with the use of nucleoside analogues, including lamivudine tablets (HBV).…

🤒 Adverse Reactions ~3 min read ▾

6 ADVERSE REACTIONS The following adverse reactions are discussed in other sections of the labeling: • Exacerbations of hepatitis B after discontinuation of treatment [see Warnings and Precautions ( 5.1 )]. • Risk of emergence of resistant HIV-1 infection [see Warnings and Precautions ( 5.2 )]. • Risk of emergence of resistant HBV infection [see Warnings and Precautions ( 5.3 )]. • Lactic acidosis and severe hepatomegaly with steatosis [see Warnings and Precautions ( 5.4 )]. The most common reported adverse reactions in those receiving lamivudine tablets (HBV) (incidence greater than or equal to 10% and reported at a rate greater than placebo) were ear, nose, and throat infections; sore throat; and diarrhea.

( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Annora Pharma Private Limited at 1-866-495-1995 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch .

6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared with rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. Clinical Trials Experience in Adult Subjects with Chronic HBV Infection Clinical adverse reactions (regardless of investigator's causality assessment) reported in greater than or equal to 10% of subjects who received lamivudine tablets (HBV) and reported at a rate greater than in subjects who received placebo are listed in Table 2.

ULN = Upper limit of normal. In subjects followed for up to 16 weeks after discontinuation of treatment, posttreatment ALT elevations were observed more frequently in subjects who had received lamivudine tablets (HBV) than in subjects who had received placebo.

🔄 Drug Interactions 159 words ▾

7 DRUG INTERACTIONS Sorbitol: Coadministration of lamivudine and sorbitol may result in decreased lamivudine concentrations; when possible, avoid chronic coadministration. Consider more frequent monitoring of HBV viral load when chronic coadministration cannot be avoided. ( 7.2 )

7.1Drugs Inhibiting Organic Cation Transporters 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 Clinical Pharmacology ( 12.3 )]. No data are available regarding interactions with other drugs that have renal clearance mechanisms similar to that of lamivudine.

7.2Sorbitol Coadministration of single doses of lamivudine and sorbitol resulted in a sorbitol dose-dependent reduction in lamivudine exposures. When possible, avoid use of sorbitol-containing medicines with lamivudine [see Clinical Pharmacology ( 12.3 )]. Consider more frequent monitoring of HBV viral load when chronic coadministration cannot be avoided.

8 USE IN SPECIFIC POPULATIONS

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

The APR uses the MACDP as a U.S. reference population for birth defects in the general population. The MACDP evaluates women and infants from a limited geographic area and does not include outcomes for births that occur at less than 20 weeks’ gestation. Of over 11,000 women exposed to lamivudine in the APR, less than 1% were treated for HBV.

The majority of women exposed to lamivudine in the APR were HIV-1-infected and were treated with higher doses of lamivudine compared with HBV mono-infected women. In addition to lamivudine, HIV-1-infected women were also treated with other concomitant medications for HIV-1 infection (see Data). The estimated rate of miscarriage for women exposed to lamivudine in the indicated population is unknown.

The estimated background rate of miscarriage in clinically recognized pregnancies in the U.S. general population is 15% to 20%. Oral administration of lamivudine to pregnant rabbits during organogenesis resulted in embryolethality at systemic exposure (AUC) similar to the recommended clinical dose; however, no adverse developmental effects were observed with oral administration of lamivudine to pregnant rats during organogenesis at plasma concentrations (C max ) 60 times the recommended clinical dose (see Data). Data Human Data: Based on prospective reports from the APR of over 11,000 exposures to lamivudine (including over 4,600 exposed in the first trimester) during pregnancy resulting in live births, less than 1% of which were patients with HBV, there was no substantial difference in birth defects with lamivudine compared with the birth defect rate of 2.7% observed in the comparator population of the MACDP.

The prevalence of birth defects in live births was 3.1% (95% CI: 2.6% to 3.6%) following first trimester exposure to lamivudine-containing regimens and 2.8% (95% CI: 2.5% to 3.3%) following second/third trimester exposure to lamivudine-containing regimens. The pharmacokinetics of lamivudine in patients with HBV or HIV-1 infection and in healthy volunteers are similar at similar doses. Lamivudine pharmacokinetics were studied in pregnant women with HIV-1 infection 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 (3 times the recommended daily dosage for HBV) with zidovudine, 10 women at 38 weeks’ gestation using 150 mg lamivudine twice daily (3 times the recommended daily dosage for HBV) with zidovudine, and 10 women at 38 weeks’ gestation using lamivudine 300 mg twice daily (6 times the recommended daily dosage for HBV) without other antiretrovirals. 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. Based on limited data at delivery, median (range) amniotic fluid concentrations of lamivudine were 3.9- (1.2- to 12.8-) fold greater compared with paired maternal serum concentrations (n = 8). Animal Data: Lamivudine was administered orally to pregnant rats (at 90, 600, and 4,000 mg per kg per day) and rabbits (at 90, 300, and 1,000 mg per kg per day and at 15, 40, and 90 mg per kg per day) during organogenesis (on gestation Days 7 through 16 [rat] and 8…

🧒 Pediatric Use 55 words ▾

8.4Pediatric Use Lamivudine tablets (HBV) is indicated for the treatment of chronic hepatitis B virus infection in pediatric patients aged 2 to 17 years [see Indications and Usage (1), Clinical Pharmacology (12.3), Clinical Studies (14.2)]. The safety and efficacy of lamivudine tablets (HBV) in pediatric patients younger than 2 years have not been established.

🧓 Geriatric Use 76 words ▾

8.5Geriatric Use Clinical trials of lamivudine tablets (HBV) 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 tablets (HBV) in elderly patients reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy [see Dosage and Administration ( 2.4 ), Clinical Pharmacology ( 12.3 )].

🆘 Overdosage 64 words ▾

10 OVERDOSAGE There is no known specific treatment for overdose with lamivudine tablets (HBV). 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 CLINICAL PHARMACOLOGY

12.1Mechanism of Action Lamivudine is an antiviral agent with activity against HBV [see Microbiology ( 12.4 )].

12.3Pharmacokinetics Pharmacokinetics in Adults The pharmacokinetic properties of lamivudine have been studied as single and multiple oral doses ranging from 5 mg to 600 mg per day administered to HBV-infected subjects. Absorption and Bioavailability: Following single oral doses of 100 mg, the peak serum lamivudine concentration (C max ) in HBV-infected patients (steady state) and healthy subjects (single dose) was 1.28 ± 0.56 mcg per mL and 1.05 ± 0.32 mcg per mL (mean ± SD), respectively, which occurred between 0.5 and 2 hours after administration.

The area under the plasma concentration versus time curve (AUC [0 to 24h] ) following 100-mg lamivudine oral single and repeated daily doses to steady state was 4.3 ± 1.4 (mean ± SD) and 4.7 ± 1.7 mcg•hour per mL, respectively. The relative bioavailability of the tablet and oral solution were demonstrated in healthy subjects. Although the solution demonstrated a slightly higher peak serum concentration (C max ), there was no significant difference in systemic exposure (AUC) between the oral solution and the tablet.

Therefore, the oral solution and the tablet may be used interchangeably. After oral administration of lamivudine once daily to HBV-infected adults, the AUC and C max increased in proportion to dose over the range from 5 mg to 600 mg once daily. Absolute bioavailability in 12 adult subjects was 86% ± 16% (mean ± SD) for the 150-mg tablet and 87% ± 13% for the 10-mg-per mL oral solution.

Effects of Food on Oral Absorption: Lamivudine tablets (HBV) may be administered with or without food. The 100-mg tablet was administered orally to 24 healthy subjects on 2 occasions, once in the fasted state and once with food (standard meal: 967 kcal; 67 grams fat, 33 grams protein, 58 grams carbohydrate). 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 HIV-1-infected 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 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 oral dose after 12 hours).

Serum concentrations of this metabolite have not been determined. Lamivudine is not significantly metabolized by cytochrome P450 enzymes. Elimination: The majority of lamivudine is eliminated unchanged in urine by active organic cationic secretion.

In 9 healthy subjects given a single 300-mg oral dose of lamivudine, renal clearance was 199.7 ± 56.9 mL per min (mean ± SD). In 20 HIV-1-infected subjects given a single IV dose, renal clearance was 280.4 ± 75.2 mL per min (mean ± SD), representing 71% ± 16% (mean ± SD) of total clearance of lamivudine. In most single-dose trials in HIV-1-infected subjects, HBV-infected subjects, or healthy subjects with serum sampling for 24 hours after dosing, the observed mean elimination half-life (t 1/2 ) ranged from 5 to 7 hours.

In HIV-1-infected subjects, total clearance was 398.5 ± 69.1 mL per min (mean ± SD). Oral clearance and elimination half-life were independent of dose and body weight over an oral dosing range of 0.25 to 10 mg per kg. Specific Populations Patients with Renal Impairment: The pharmacokinetic properties of lamivudine have been determined in healthy adults and in adults with impaired renal function, with and without hemodialysis (Table 5).

17 PATIENT COUNSELING INFORMATION Advise the patient to read the FDA-approved patient labeling (Patient Information). Severe Acute Exacerbation of Hepatitis after Discontinuation of Treatment Inform patients that discontinuation of anti-hepatitis B therapy, including lamivudine tablets (HBV), may result in severe acute exacerbations of hepatitis B including decompensation of liver disease. Advise patients not to discontinue lamivudine tablets (HBV) without first informing their healthcare provider [see Warnings and Precautions ( 5.1 )].

Risk of Development of HIV-1 Resistance in Patients with HIV-1 Co-infection Counsel patients on the importance of testing for HIV to avoid inappropriate therapy and development of resistance to HIV. HIV counseling and testing should be offered before starting lamivudine tablets (HBV) and periodically during therapy. Inform patients that if they have or develop HIV infection and are not receiving effective HIV treatment, lamivudine tablets (HBV) may increase the risk of development of resistance to HIV medications.

Advise patients that lamivudine tablets (HBV) contains a lower dose of the same active ingredient (lamivudine) as HIV drugs containing lamivudine [see Dosage and Administration ( 2.1 ), Warnings and Precautions ( 5.2 )]. Emergence of HBV Resistance Inform patients that emergence of resistant hepatitis B virus and worsening of disease can occur during treatment. Patients should promptly report any new or worsening symptoms to their physician [see Warnings and Precautions ( 5.3 )].

Lactic Acidosis/Severe Hepatomegaly with Steatosis Advise patients that lactic acidosis and severe hepatomegaly with steatosis have been reported with use of nucleoside analogues and other antiretrovirals. Advise patients to stop taking lamivudine tablets (HBV) if they develop clinical symptoms suggestive of lactic acidosis or pronounced hepatotoxicity [see Warnings and Precautions ( 5.4 )]. Hepatitis B Transmission Advise patients that treatment with lamivudine tablets (HBV) has not been shown to reduce the risk of transmission of HBV to others through sexual contact or blood contamination.

Drug Interactions Inform patients that lamivudine tablets (HBV) may interact with some drugs; therefore, patients should be advised to report to their healthcare provider the use of any prescription or non-prescription medication, or herbal products. Advise patients to avoid chronic use of sorbitol-containing prescription and over-the-counter medicines when possible.
