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.

🤰 Pregnancy 84 words ▾

Pregnancy: Teratogenic Effects: Pregnancy Category B: There are no adequate and well-controlled studies with the use of Metronidazole Topical Lotion in pregnant women. Metronidazole crosses the placental barrier and enters the fetal circulation rapidly. No fetotoxicity was observed after oral administration of metronidazole in rats or mice.

However, because animal reproduction studies are not always predictive of human response and since oral metronidazole has been shown to be a carcinogen in some rodents, this drug should be used during pregnancy only if clearly needed.

🧒 Pediatric Use 12 words ▾

Pediatric Use: Safety and effectiveness in pediatric patients have not been established.

🧬 Clinical Pharmacology 128 words ▾

CLINICAL PHARMACOLOGY The mechanisms by which metronidazole acts in the treatment of rosacea are unknown, but appear to include an anti-inflammatory effect. Pharmacokinetics: Absorption of metronidazole after topical application of Metronidazole Topical Lotion is less complete and more prolonged than after oral administration. Detectable plasma levels were found in all subjects following the administration of a 1 gram dose of Metronidazole Topical Lotion (containing 7.5 mg of metronidazole) applied every morning and evening for 4 days to the faces of 8 patients.

The highest concentration (96 ng/mL) seen following the morning dose on Day 5 was approximately 80 times lower than the peak concentrations produced by a single 250 mg tablet of metronidazole. The mean (± SD) AUC 0-24 after twice daily administration was 962 ± 373 ng.hr/mL.

It is for external use only. 3. Avoid contact with the eyes. 4. Cleanse affected area(s) before applying this medication. 5. Patients should report any adverse reaction to their physician.

⚠️ Precautions ~3 min read ▾

PRECAUTIONS General: Topical metronidazole formulations have been reported to cause tearing of the eyes. Therefore, contact with the eyes should be avoided. If a reaction suggesting local irritation occurs, patients should be directed to use the medication less frequently or discontinue use.

Metronidazole is a nitroimidazole and should be used with care in patients with evidence or history of blood dyscrasia. Information for Patients: Patients using Metronidazole Topical Lotion should receive the following information and instructions: 1. This medication is to be used only as directed by the physician.

2. It is for external use only. 3.

Avoid contact with the eyes. 4. Cleanse affected area(s) before applying this medication.

5. Patients should report any adverse reaction to their physician. Drug Interactions: Oral metronidazole has been reported to potentiate the anticoagulant effect of warfarin and coumarin anticoagulants, resulting in a prolongation of prothrombin time.

The effect of topical metronidazole on prothrombin time is not known. Carcinogenesis, Mutagenesis, Impairment of Fertility: Metronidazole has shown evidence of carcinogenic activity in a number of studies involving chronic, oral administration in mice and rats. Metronidazole has not been assessed for carcinogenic activity following topical administration.

In several long term studies in mice, oral doses of approximately 200 mg/m 2 /day (approximately 20 times the exposure of a patient that received the estimated maximum human topical daily dose (assuming 100% bioavailability and following normalization of the data on the basis of the body surface area)) or greater were associated with increase incidences of lung tumors in male mice and lymphomas in female mice. In several long-term studies in rats, oral administration of metronidazole resulted in increased incidences of mammary and hepatic tumors in female rats and testicular tumors and pituitary adenomas in male rats at dosages of approximately 1600 mg/m 2 /day (approximately 170 times the exposure of a patient that received the estimated maximum human topical daily dose (assuming 100% bioavailability and following normalization of the data on the basis of the body surface area)) or greater.

In another oral study, an increase of mammary tumors was observed in female rats that received approximately 160 mg/m 2 /day (approximately 17 times the exposure of a patient that received the estimated maximum human topical daily dose (assuming 100% bioavailability and the following normalization of the data on the basis of the body surface area)). Ultraviolet radiation-induced carcinogenesis was enhanced in albino mice by intraperitoneal injection of metronidazole at a dosage of 45 mg/m 2 /day, 5 days per week for 10 weeks, as indicated by a decreased latency period to the development of skin neoplasms.

It is unclear how this level of exposure compares to the clinical situation with respect to the concentration of the drug or metabolics in the skin. This study did not determine if metronidazole must be present during exposure to ultraviolet radiation in order to enhance tumor formation; metronidazole may promote tumor formation in cells that have previously been initiated by ultraviolet radiation. Metronidazole exhibited mutagenic activity in several in vitro bacterial and mammalian assay systems.

Intraperitoneal administration of metronidazole to mice resulted in a dosage-dependent increase in the incidence of chromosomal aberrations in peripheral lymphocytes was reported in patients with Crohn’s disease who were treated with metronidazole for 1 to 24 months at a dosage of 200 to 1200 mg/day. However, similar results were not observed in another study, in which humans were treated for 8 months. In rats, oral metronidazole at a dosage of approximately 1800 mg/m 2 /day (approximately 200 times the exposure of a patient that received the estimated maximum human topical daily dose (assuming 100% bioavailability and follow… [Excerpted — this section continues on DailyMed.]

🍼 Nursing Mothers 64 words ▾

Nursing Mothers: After oral administration, metronidazole is secreted in breast milk in concentrations similar to those found in the plasma. Even though blood levels are significantly lower with topically applied metronidazole than those achieved after oral administration of metronidazole, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

🧬 Pharmacokinetics 106 words ▾

Pharmacokinetics: Absorption of metronidazole after topical application of Metronidazole Topical Lotion is less complete and more prolonged than after oral administration. Detectable plasma levels were found in all subjects following the administration of a 1 gram dose of Metronidazole Topical Lotion (containing 7.5 mg of metronidazole) applied every morning and evening for 4 days to the faces of 8 patients. The highest concentration (96 ng/mL) seen following the morning dose on Day 5 was approximately 80 times lower than the peak concentrations produced by a single 250 mg tablet of metronidazole.

The mean (± SD) AUC 0-24 after twice daily administration was 962 ± 373 ng.hr/mL.

🔬 Clinical Studies ~1 min read ▾

CLINICAL STUDIES A controlled clinical study was conducted in 144 patients with moderate to severe rosacea, in which Metronidazole Topical Lotion was compared with its vehicle. Applications were made twice daily for 12 weeks during which patients were instructed to avoid spicy foods, thermally hot foods and drinks, alcoholic beverages, and caffeine. Patients were also provided samples of a soapless cleansing lotion and, if requested, a moisturizer.

Metronidazole Topical Lotion was significantly more effective than its vehicle in mean percent reduction of inflammatory lesions associated with rosacea and in the investigators' global assessment of improvement. The results of the mean percent reduction in inflammatory lesion counts from baseline after 12 weeks of treatment and the investigators' global assessment of improvement at week 12 are presented in the following table: Efficacy Outcomes at Week 12 Mean Percent reduction in Inflammatory Lesion Counts from Baseline Metronidazole Topical Lotion N=65 Vehicle Lotion N=60 55% 20% Investigators' Global Assessment of Improvement (percent change from baseline) Worse No Change Minimal Improvement Definite Improvement Marked Improvement Clear Metronidazole Topical Lotion N=65 5% 12% 11% 32% 32% 8% Vehicle Lotion N=60 15% 27% 23% 15% 20% 0% The scale is based on the following definitions: Worse: Exacerbation of either erythema or quantitative assessment of papules and/or pustules.

No Change: Condition remains the same. Minimal Improvement: Slight improvement in the quantitative assessment of papules and/or pustules, and/or slight improvement in erythema. Definite Improvement: More pronounced improvement in the quantitative assessment of papules and/or pustules, and/or more pronounced improvement in erythema.

Marked Improvement: Obvious improvement in the quantitative assessment of papules and/or pustules, and/or obvious improvement in erythema. Clear: No papules or pustules and minimal residual or no erythema.

In rats, oral metronidazole at a dosage of approximately 1800 mg/m 2 /day (approximately 200 times the exposure of a patient that received the estimated maximum human topical daily dose (assuming 100% bioavailability and following normalization of the data on the basis of body surface area)) induced inhibition of spermatogenesis and severe testicular degeneration.

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

Medicare Part D (outpatient prescription) spending for Metronidazole — the program that covers self-administered drugs. 23 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 Metronidazole. 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.
