📖 What it is MedlinePlus · NLM

Colchicine is used to prevent gout attacks (sudden, severe pain in one or more joints caused by abnormally high levels of a substance called uric acid in the blood) in adults. Colchicine is also used to relieve the pain of gout attacks when they occur. Colchicine is also used to treat familial Mediterranean fever (FMF; an inborn condition that causes episodes of fever, pain, and swelling of the stomach area, lungs, and joints) in adults and children 4 years of age and older. Colchicine (Lodoco®) is used to reduce the risk of heart attack, stroke, cardiovascular death, and needing certain ty...

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.
Medicaid paysCMS SDUD · 12 mo No recent Medicaid claims on file for this NDC — rare and low-volume NDCs are suppressed in the public data.

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.

1 INDICATIONS AND USAGE Colchicine is an alkaloid indicated for: • Familial Mediterranean fever (FMF) in adults and children 4 years or older (1.2).

1.2Familial Mediterranean Fever (FMF) Colchicine tablets are indicated in adults and children four years or older for treatment of Familial Mediterranean Fever (FMF).

⏱️ Dosage and Administration ~3 min read ▾

2 DOSAGE AND ADMINISTRATION The long-term use of colchicine is established for FMF. The recommended dosage of colchicine tablets depends on the patient's age, renal function, hepatic function and use of co-administered drugs [see Dosage and Administration (2.4, 2.5 , 2.6 ]. Colchicine tablets are administered orally without regard to meals.

Colchicine tablets are not an analgesic medication and should not be used to treat pain from other causes. FMF: Adults and children older than 12 years 1.2 to 2.4 mg; children 6 to 12 years 0.9 to 1.8 mg; children 4 to 6 years 0.3 to 1.8 mg ( 2.2 , 2.3). o Give total daily dose in one or two divided doses ( 2.2 ). o Increase or decrease the dose as indicated and as tolerated in increments of 0.3 mg/day, not to exceed the maximum recommended daily dose ( 2.2 ). Colchicine tablets are administered orally without regard to meals.

See full prescribing information (FPI) for dose adjustment regarding patients with impaired renal function (2.5), impaired hepatic function ( 2.6 ), the patient's age ( 2.3 , 8.5 ) or use of co-administered drugs ( 2.4 ).

2.2FMF The recommended dosage of colchicine tablets for FMF in adults is 1.2 mg to 2.4 mg daily. Colchicine tablets should be increased as needed to control disease and as tolerated in increments of 0.3 mg/day to a maximum recommended daily dose. If intolerable side effects develop, the dose should be decreased in increments of 0.3 mg/day. The total daily colchicine tablets dose may be administered in one to two divided doses.

2.3Recommended Pediatric Dosage FMF The recommended dosage of colchicine tablets for FMF in pediatric patients 4 years of age and older is based on age. The following daily doses may be given as a single or divided dose twice daily: • Children 4 to 6 years: 0.3 mg to 1.8 mg daily • Children 6 to 12 years: 0.9 mg to 1.8 mg daily • Adolescents older than 12 years: 1.2 mg to 2.4 mg daily

2.4Dose Modification for Co-administration of Interacting Drugs Concomitant Therapy Co-administration of colchicine tablets with drugs known to inhibit CYP3A4 and/or P-glycoprotein (P-gp) increases the risk of colchicine-induced toxic effects ( Table 1 ). If patients are taking or have recently completed treatment with drugs listed in Table 1 within the prior 14 days, the dose adjustments are as shown in the table below [see Drug Interactions ( 7 )]. Table 1.

Colchicine Tablets Dose Adjustment for Co-administration with Interacting Drugs if No Alternative Available * Strong CYP3A4 Inhibitors † Drug Noted or Anticipated Outcome FMF Original Intended Dosage Adjusted Dose Atazanavir Clarithromycin Darunavir/ Ritonavir ‡ Indinavir Itraconazole Ketoconazole Lopinavir/ Ritonavir ‡ Nefazodone Nelfinavir Ritonavir Saquinavir Telithromycin Tipranavir/ Ritonavir ‡ Significant increase in colchicine plasma levels*; fatal colchicine toxicity has been reported with clarithromycin, a strong CYP3A4 inhibitor.

Similarly, significant increase in colchicine plasma levels is anticipated with other strong CYP3A4 inhibitors. Maximum daily dose of 1.2 to 2.4 mg Maximum daily dose of 0.6 mg (may be given as 0.3 mg twice a day) Moderate CYP3A4 Inhibitors Drug Noted or Anticipated Outcome FMF Original Intended Dosage Adjusted Dose Amprenavir ‡ Aprepitant Diltiazem Erythromycin Fluconazole Fosamprenavir ‡ (prodrug of Amprenavir) Grapefruit juice Verapamil Significant increase in colchicine plasma concentration is anticipated.

⛔ Contraindications 83 words ▾

4 CONTRAINDICATIONS Patients with renal or hepatic impairment should not be given colchicine in conjunction with P-gp or strong CYP3A4 inhibitors (this includes all protease inhibitors except fosamprenavir). In these patients, life-threatening and fatal colchicine toxicity has been reported with colchicine taken in therapeutic doses. Patients with renal or hepatic impairment should not be given colchicine in conjunction with P-gp or strong CYP3A4 inhibitors (5.3).

In these patients, life-threatening and fatal colchicine toxicity has been reported with colchicine taken in therapeutic doses (7).

⚠️ Warnings and Cautions ~2 min read ▾

5 WARNINGS AND PRECAUTIONS Fatal overdoses have been reported with colchicine in adults and children. Keep colchicine out of the reach of children ( 5.1 , 10 ). • Blood dyscrasias : myelosuppression, leukopenia, granulocytopenia, thrombocytopenia and aplastic anemia have been reported ( 5.2 ). • Monitor for toxicity and if present consider temporary interruption or discontinuation of colchicine ( 5.2 , 5.3 , 5.4 , 6 , 10 ). • Drug interaction P-gp and/or CYP3A4 inhibitors : Co-administration of colchicine with P-gp and/or strong CYP3A4 inhibitors has resulted in life-threatening interactions and death ( 5.3 , 7 ). • Neuromuscular toxicity : Myotoxicity including rhabdomyolysis may occur, especially in combination with other drugs known to cause this effect.

Consider temporary interruption or discontinuation of colchicine ( 5.4 , 7 )

5.1Fatal Overdose Fatal overdoses, both accidental and intentional, have been reported in adults and children who have ingested colchicine [ see Overdosage (10)]. Colchicine should be kept out of the reach of children.

5.2Blood Dyscrasias Myelosuppression, leukopenia, granulocytopenia, thrombocytopenia, pancytopenia and aplastic anemia have been reported with colchicine used in therapeutic doses.

5.3Drug Interactions Colchicine is a P-gp and CYP3A4 substrate. Life-threatening and fatal drug interactions have been reported in patients treated with colchicine given with P-gp and strong CYP3A4 inhibitors. If treatment with a P-gp or strong CYP3A4 inhibitor is required in patients with normal renal and hepatic function, the patient’s dose of colchicine may need to be reduced or interrupted [see Drug Interactions (7)] .

Use of colchicine in conjunction with P-gp or strong CYP3A4 inhibitors (this includes all protease inhibitors except fosamprenavir) is contraindicated in patients with renal or hepatic impairment [ see Contraindications (4)].

5.4Neuromuscular Toxicity Colchicine-induced neuromuscular toxicity and rhabdomyolysis have been reported with chronic treatment in therapeutic doses. Patients with renal dysfunction and elderly patients, even those with normal renal and hepatic function, are at increased risk. Concomitant use of atorvastatin, simvastatin, pravastatin, fluvastatin, lovastatin, gemfibrozil, fenofibrate, fenofibric acid or benzafibrate (themselves associated with myotoxicity) or cyclosporine with colchicine may potentiate the development of myopathy [ see Drug Interactions (7)].

Once colchicine is stopped, the symptoms generally resolve within one week to several months.

🤒 Adverse Reactions ~1 min read ▾

6 ADVERSE REACTIONS FMF Gastrointestinal tract adverse effects are the most frequent side effects in patients initiating colchicine, usually presenting within 24 hours, and occurring in up to 20% of patients given therapeutic doses. Typical symptoms include cramping, nausea, diarrhea, abdominal pain and vomiting. These events should be viewed as dose-limiting if severe, as they can herald the onset of more significant toxicity.

FMF: Most common adverse reactions (up to 20%) are abdominal pain, diarrhea, nausea and vomiting. These effects are usually mild, transient and reversible upon lowering the dose ( 6 ). To report SUSPECTED ADVERSE REACTIONS, contact Granules Pharmaceuticals Inc. at 1-877-770-3183 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch .

6.2Postmarketing Experience Serious toxic manifestations associated with colchicine include myelosuppression, disseminated intravascular coagulation and injury to cells in the renal, hepatic, circulatory and central nervous systems. These most often occur with excessive accumulation or overdosage [ see Overdosage (10)]. The following adverse reactions have been identified with colchicine.

These have been generally reversible upon temporarily interrupting treatment or lowering the dose of colchicine. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

7 DRUG INTERACTIONS Colchicine is a substrate of the efflux transporter P-glycoprotein (P-gp). Of the cytochrome P450 enzymes tested, CYP3A4 was mainly involved in the metabolism of colchicine. If colchicine is administered with drugs that inhibit P-gp, most of which also inhibit CYP3A4, increased concentrations of colchicine are likely.

Fatal drug interactions have been reported. Physicians should ensure that patients are suitable candidates for treatment with colchicine and remain alert for signs and symptoms of toxicities related to increased colchicine exposure as a result of a drug interaction. Signs and symptoms of colchicine toxicity should be evaluated promptly and, if toxicity is suspected, colchicine should be discontinued immediately.

Table 4 provides recommendations as a result of other potentially significant drug interactions. Table 1 provides recommendations for strong and moderate CYP3A4 inhibitors and P-gp inhibitors. Table 4.

Other Potentially Significant Drug Interactions Concomitant Drug Class or Food Noted or Anticipated Outcome Clinical Comment HMG-Co A Reductase Inhibitors: atorvastatin, fluvastatin, lovastatin, pravastatin, simvastatin Pharmacokinetic and/or pharmacodynamic interaction: the addition of one drug to a stable long-term regimen of the other has resulted in myopathy and rhabdomyolysis (including a fatality) Weigh the potential benefits and risks and carefully monitor patients for any signs or symptoms of muscle pain, tenderness, or weakness, particularly during initial therapy; monitoring CPK (creatine phosphokinase) will not necessarily prevent the occurrence of severe myopathy.

Other Lipid-Lowering Drugs: fibrates, gemfibrozil Digitalis Glycosides: digoxin P-gp substrate; rhabdomyolysis has been reported Co-administration of P-gp and/or CYP3A4 inhibitors (e.g., clarithromycin or cyclosporine) have been demonstrated to alter the concentration of colchicine. The potential for drug-drug interactions must be considered prior to and during therapy. See FPI for a complete list of reported and potential interactions ( 2.4 , 5.3 , 7 ).

👥 Use in Specific Populations ~3 min read ▾

8 USE IN SPECIFIC POPULATIONS In the presence of mild to moderate renal or hepatic impairment, adjustment of dosing is not required for treatment of FMF, but patients should be monitored closely ( 8.6 ). In FMF patients with severe renal impairment, start with 0.3 mg/day, and any increase in dose should be done with close monitoring ( 8.6). In patients with severe hepatic impairment, a dose reduction may be needed in FMF patients.

( 8.6 , 8.7). For FMF patients undergoing dialysis, the starting dose should be 0.3 mg /day and dosing can be increased with close monitoring ( 8.6). Females and Males of Reproductive Potential: Advise males that colchicine may transiently impair fertility ( 8.3 ).

Geriatric Use: The recommended dose of colchicine should be based on renal function ( 8.5 ).

8.1Pregnancy Risk Summary Available data from published literature on colchicine use in pregnancy over several decades have not identified any drug associated risks for major birth defects, miscarriage, or adverse maternal or fetal outcomes (see Data). Colchicine crosses the human placenta. Although animal reproductive and developmental studies were not conducted with colchicine, published animal reproduction and development studies indicate that colchicine causes embryofetal toxicity, teratogenicity and altered postnatal development at exposures within or above the clinical therapeutic range.

The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.

Data Human Data Available data from published observational studies, case series, and case reports over several decades do not suggest an increased risk for major birth defects or miscarriage in pregnant women with rheumatic diseases (such as rheumatoid arthritis, Behcet’s disease, or Familial Mediterranean Fever (FMF) treated with colchicine at therapeutic doses during pregnancy. Limitations of these data include the lack of randomization and inability to control for confounders such as underlying maternal disease and maternal use of concomitant medications.

8.2Lactation Risk Summary Colchicine is present in human milk (see Data) . Adverse events in breastfed infants have not been reported in the published literature after administration of colchicine to lactating women. There are no data on the effects of colchicine on milk production.

The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for colchicine and any potential adverse effects on the breastfed child from colchicine or from the underlying maternal condition. Data Limited published data from case reports and a small lactation study demonstrate that colchicine is present in breastmilk. A systematic review of literature reported no adverse effects in 149 breastfed children.

In a prospective observational cohort study, no gastrointestinal or other symptoms were reported in 38 colchicine-exposed breastfed infants.

8.3Females and Males of Reproductive Potential Infertility Case reports and epidemiology studies in human male subjects on colchicine therapy indicated that infertility from colchicine is rare and may be reversible. A case report indicated that azoospermia was reversed when therapy was stopped. Case reports and epidemiology studies in female subjects on colchicine therapy have not established a clear relationship between colchicine use and female infertility.

However, since the progression of FMF without treatment may result in infertility, the use of colchicine needs to be weighed against the potential risks [see Nonclinical Toxicology ( 13.1 )].

8.4Pediatric Use The safety and efficacy of colchicine in children of all ages with FMF has been evaluated in uncontrolled studies. There does not appear to be an adverse effect on growth in children with FMF treated long-term with colchicine.

🧓 Geriatric Use 68 words ▾

8.5Geriatric Use Clinical studies with colchicine for treatment of FMF did not include sufficient numbers of patients aged 65 years and older to determine whether they respond differently from younger patients. In general, dose selection for an elderly patient should be cautious, reflecting the greater frequency of decreased renal function, concomitant disease or other drug therapy [see Dosage and Administration (2.4), Clinical Pharmacology ( 12.3 ) .

🆘 Overdosage ~1 min read ▾

10 OVERDOSAGE The exact dose of colchicine that produces significant toxicity is unknown. Fatalities have occurred after ingestion of a dose as low as 7 mg over a four-day period, while other patients have survived after ingesting more than 60 mg. A review of 150 patients who overdosed on colchicine found that those who ingested less than 0.5 mg/kg survived and tended to have milder toxicities such as gastrointestinal symptoms, whereas those who took 0.5 to 0.8 mg/kg had more severe reactions such as myelosuppression.

There was 100% mortality in those who ingested more than 0.8 mg/kg. The first stage of acute colchicine toxicity typically begins within 24 hours of ingestion and includes gastrointestinal symptoms such as abdominal pain, nausea, vomiting, diarrhea and significant fluid loss, leading to volume depletion. Peripheral leukocytosis may also be seen.

Life-threatening complications occur during the second stage, which occurs 24 to 72 hours after drug administration, attributed to multiorgan failure and its consequences. Death is usually a result of respiratory depression and cardiovascular collapse. If the patient survives, recovery of multiorgan injury may be accompanied by rebound leukocytosis and alopecia starting about one week after the initial ingestion.

Treatment of colchicine poisoning should begin with gastric lavage and measures to prevent shock. Otherwise, treatment is symptomatic and supportive. No specific antidote is known.

Colchicine is not effectively removed by dialysis [see Clinical Pharmacology (12.3)].

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action The mechanism by which colchicine exerts its beneficial effect in patients with FMF has not been fully elucidated; however, evidence suggests that colchicine may interfere with the intracellular assembly of the inflammasome complex present in neutrophils and monocytes that mediates activation of interleukin-1β. Additionally, colchicine disrupts cytoskeletal functions through inhibition of β-tubulin polymerization into microtubules and consequently prevents the activation, degranulation and migration of neutrophils.

12.3Pharmacokinetics Absorption In healthy adults, colchicine is absorbed when given orally, reaching a mean C max of 2.5 ng/mL (range 1.1 to 4.4 ng/mL) in one to two hours (range 0.5 to 3 hours) after a single dose administered under fasting conditions. Following oral administration of colchicine given as 1.8 mg colchicine over one hour to healthy, young adults under fasting conditions, colchicine appears to be readily absorbed, reaching mean maximum plasma concentrations of 6.2 ng/mL at a median 1.81 hours (range: 1 to 2.5 hours).

Following administration of the nonrecommended high-dose regimen (4.8 mg over six hours), mean maximal plasma concentrations were 6.8 ng/mL, at a median 4.47 hours (range: 3.1 to 7.5 hours). After ten days on a regimen of 0.6 mg twice daily, peak concentrations are 3.1 to 3.6 ng/mL (range 1.6 to 6 ng/mL), occurring 1.3 to 1.4 hours postdose (range 0.5 to 3 hours). Mean pharmacokinetic parameter values in healthy adults are shown in Table 5.

Table 5. Mean (%CV) Pharmacokinetic Parameters in Healthy Adults Given Colchicine C max (Colchicine ng/mL) T max* (h) Vd/F (L) CL/F (L/hr) t 1/2 (h) Colchicine 0.6 mg Single Dose (N=13) 2.5 (28.7) 1.5 (1 to 3) 341.5 (54.4) 54.1 (31) - Colchicine 0.6 mg Twice Daily x 10 Days (N=13) 3.6 (23.7) 1.3 (0.5 to 3) 1150 (18.7) 30.3 (19) 26.6 (16.3) * T max mean (range) CL = Dose/AUC 0-t (calculated from mean values) Vd = CL/Ke (calculated from mean values) In some subjects, secondary colchicine peaks are seen, occurring between three and 36 hours postdose and ranging from 39 to 155% of the height of the initial peak.

These observations are attributed to intestinal secretion and reabsorption and/or biliary recirculation. Absolute bioavailability is reported to be approximately 45%. Administration of colchicine with food has no effect on the rate of colchicine absorption but does decrease the extent of colchicine by approximately 15%.

This is without clinical significance. Distribution The mean apparent volume of distribution in healthy young volunteers is approximately 5 to 8 L/kg. Colchicine binding to serum protein is low, 39 ± 5%, primarily to albumin regardless of concentration.

Colchicine crosses the placenta (plasma levels in the fetus are reported to be approximately 15% of the maternal concentration). Colchicine also distributes into breast milk at concentrations similar to those found in the maternal serum [see Use in Specific Populations ( 8.1 , 8.2 )]. Metabolism Colchicine is demethylated to two primary metabolites, 2-O-demethylcolchicine and 3-O-demethylcolchicine (2- and 3-DMC, respectively) and one minor metabolite, 10-O-demethylcolchicine (also known as colchiceine).

In vitro studies using human liver microsomes have shown that CYP3A4 is involved in the metabolism of colchicine to 2-and 3-DMC. Plasma levels of these metabolites are minimal (less than 5% of parent drug). Elimination/Excretion In healthy volunteers (n=12), 40 to 65% of 1 mg orally administered colchicine was recovered unchanged in urine.

Enterohepatic recirculation and biliary excretion are also postulated to play a role in colchicine elimination. Following multiple oral doses (0.6 mg twice daily), the mean elimination half-lives in young healthy volunteers (mean age 25 to 28 years of age) is 26.6 to 31.2 hours. Colchicine is a substrate of P-gp.

🔬 Clinical Studies ~1 min read ▾

14 CLINICAL STUDIES The evidence for the efficacy of colchicine in patients with FMF is derived from the published literature. Three randomized, placebo-controlled studies were identified. The three placebo-controlled studies randomized a total of 48 adult patients diagnosed with FMF and reported similar efficacy endpoints as well as inclusion and exclusion criteria.

One of the studies randomized 15 patients with FMF to a six-month crossover study during which five patients discontinued due to study noncompliance. The ten patients completing the study experienced five attacks over the course of 90 days while treated with colchicine compared to 59 attacks over the course of 90 days while treated with placebo. Similarly, the second study randomized 22 patients with FMF to a four-month crossover study during which nine patients discontinued due to lack of efficacy while receiving placebo or study noncompliance.

The 13 patients completing the study experienced 18 attacks over the course of 60 days while treated with colchicine compared to 68 attacks over the course of 60 days while treated with placebo. The third study was discontinued after an interim analysis of six of the 11 patients enrolled had completed the study; results could not be confirmed. Open-label experience with colchicine in adults and children with FMF is consistent with the randomized, controlled trial experience and was utilized to support information on the safety profile of colchicine and for dosing recommendations.

13 NONCLINICAL TOXICOLOGY

13.1Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenesis Two-year studies were conducted in mice and rats to assess the carcinogenic potential of colchicine. No evidence of colchicine-related tumorigenicity was observed in mice or rats at colchicine oral doses up to 3 and 2 mg/kg/day, respectively (approximately six and eight times, respectively, the maximum recommended human dose of 2.4 mg on a mg/m 2 basis). Mutagenesis Colchicine was negative for mutagenicity in the bacterial reverse mutation assay.

In a chromosomal aberration assay in cultured human white blood cells, colchicine treatment resulted in the formation of micronuclei. Since published studies demonstrated that colchicine induces aneuploidy from the process of mitotic nondisjunction without structural DNA changes, colchicine is not considered clastogenic, although micronuclei are formed. Impairment of Fertility No studies of colchicine effects on fertility were conducted with colchicine.

However, published nonclinical studies demonstrated that colchicine-induced disruption of microtubule formation affects meiosis and mitosis. Reproductive studies also reported abnormal sperm morphology and reduced sperm counts in males, and interference with sperm penetration, second meiotic division and normal cleavage in females when exposed to colchicine. Colchicine administered to pregnant animals resulted in fetal death and teratogenicity.

These effects were dose-dependent, with the timing of exposure critical for the effects on embryofetal development. The nonclinical doses evaluated were generally higher than an equivalent human therapeutic dose, but safety margins for reproductive and developmental toxicity could not be determined.

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 it is currently marketed — but Golden State Medical Supply, Inc. has reported a marketing end date of 2027-12-31, after which this package is expected to stop being marketed. 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 30 tablets (51407-0082-30). Each has its own NDC and its own page — see the package list near the top of this page.
Who lists this product with the FDA?
Golden State Medical Supply, Inc. is the labeler of record for this NDC — the company under whose FDA-assigned code the package is listed. The labeler may be the manufacturer itself or a distributor marketing the product under its own code.
