Why two NDCs? The FDA registers this code as 15370-220-99 — 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 → 15370-0220-99. Same drug, same package — only the format differs.

💊 What it looks like

Color Yellow
One label can cover several strengths, so colors may be combined — always confirm a loose pill against the dispensed prescription label or a pharmacist.
Where does this data come from?
Physical description (imprint, shape, color, scoring, coating) from this product’s FDA Structured Product Labeling (SPL), mirrored from DailyMed / openFDA.

🧪 Inactive Ingredients / Excipients

Inactive ingredients, also called excipients, are components of the drug product other than the active ingredient. They may include fillers, dyes, coatings, preservatives, flavors, or other formulation ingredients.

A current SPL was checked, but it does not contain a structured or narrative inactive-ingredient list for this product. This does not mean the product has no inactive ingredients.
Where does this data come from?
Source: official FDA Structured Product Labeling (SPL) via DailyMed and the openFDA label index. Structured IACT rows and label-wide narrative are kept separate; availability and product-level specificity depend on the submitted label.

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

ℹ️
No price is published for this exact package yet. CMS surveys NADAC per package size, so a different pack of the same drug often has one.
Try another pack size: 2 pouches
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.

🛡️ Latest patent/protection date listed: FDA patent/protection data lists protections through May 2042. This may affect when a full generic version becomes widely available, but it is not a guaranteed launch date.

Why the date isn’t exact: Generic timing can change because patents may be challenged, settled, licensed, added, removed, or worked around with a narrower label — and FDA approval does not always mean a pharmacy can get the generic today.

🏛️FDA exclusivity
FDA-granted marketing protection. It’s separate from patents and may be shorter than patent protection.
🧪Product / substance patents
Patents covering the active ingredient, product, formulation, or related drug features.
🎯Method-of-use patents
Patents covering specific approved uses. These can sometimes be carved out with a “skinny label,” but not always.
🛈 What do these terms mean?
Patent
Legal protection listed in the Orange Book that may delay generic approval or launch. Issued by the U.S. Patent & Trademark Office.
Substance patent
Covers the active drug molecule itself — the hardest to design around. A generic generally can’t launch until it expires.
Formulation (product) patent
Covers a specific formulation or dosage form. A generic can sometimes work around it with a different formulation.
Method-of-use patent
A patent covering one specific approved use of the drug — not necessarily the whole molecule. A generic can sometimes launch with a “skinny label” that carves out the protected use and keeps the others.
Skinny label
A generic label that omits a still-patented use when the FDA allows it — letting a generic reach the market for the unprotected uses.
Exclusivity
FDA-granted marketing protection, separate from patents — e.g. 5-yr new chemical entity, 7-yr orphan drug, or a +6-month pediatric extension.
Paragraph IV
A generic applicant’s formal challenge to a listed patent. It can potentially lead to earlier generic entry, but often involves litigation or a settlement.
RLD / RS
Reference Listed Drug — the brand product the FDA uses as the reference for generic applications. Reference Standard — the product the FDA expects generics to compare against in bioequivalence testing.
TE / AB rating
FDA therapeutic-equivalence rating. An AB rating generally means the FDA considers a generic therapeutically equivalent to — and substitutable for — the brand.
LOE (loss of exclusivity)
The latest patent or exclusivity currently listed — the loss-of-exclusivity / latest-listed-protection date shown on this page. Paragraph-IV challenges and settlements can move the real date earlier; FDA approval and a manufacturer’s decision to market can move it later.

Built from the FDA Orange Book. The bars above are scaled to each protection’s expiry; the red LOE marker is the last one to lapse.

Common questions
Is there a generic version of this drug?
No FDA-approved generic equivalent is currently listed in the FDA Orange Book for this drug. Based on the patents and exclusivity currently listed, the Orange Book estimate is that full-label generic entry may be delayed until May 2042 — an estimate, not a guaranteed launch date.
The FDA approved a generic — why can’t I get it at my pharmacy yet?
FDA approval and pharmacy availability are two different things. The FDA can approve a generic years before it actually reaches pharmacies, because the brand company may still hold patents or have a settlement that delays the launch. A manufacturer also has to choose to make and sell it, and have supply ready. So a drug can be “FDA-approved generic exists” and still be brand-only at the counter today.
Why do different websites show different generic release dates?
Generic availability is not based on one single date. Some sources use the first exclusivity expiration, some use the last product patent, and others use the latest method-of-use patent. Patent challenges, settlements, licenses, and label carve-outs can also change the real-world launch date. This page shows the underlying Orange Book dates so you can see why estimates may differ.
What does “FDA listed” mean?
It means the product appears in the FDA’s official NDC directory. That’s a good sign a product exists and is intended for the U.S. market, but on its own it does not confirm a pharmacy can fill it today. Where we have recent retail pricing data (NADAC) for a product, we label it “Availability likely” instead.
What does a patent or protection date mean here?
It’s the latest date currently listed in the FDA Orange Book for a patent or exclusivity on the brand product. It can affect when a full generic version becomes widely available — but it is not a guaranteed generic launch date. Generics sometimes arrive earlier (through a settlement or patent challenge) or later (a manufacturer still has to make and sell one).
What does “current Orange Book estimate” mean?
It means we are using the latest patent and exclusivity dates currently listed in the FDA Orange Book. It is not a guaranteed launch date.
Can a generic come out before the last patent expires?
Sometimes. A generic company may challenge a patent, settle with the brand manufacturer, receive a license, or obtain approval with a narrower label that avoids a patented use. In other cases, the last listed protection may delay full-label generic competition.
Can a generic come out after the listed dates?
Yes. Even after patents or exclusivity expire, a generic still needs FDA approval and a manufacturer must choose to market it. Supply, litigation, business decisions, or regulatory issues can delay actual availability.
What is the difference between patents and exclusivity?
Patents are legal protections usually issued by the U.S. Patent and Trademark Office. FDA exclusivity is marketing protection granted by the FDA. They are separate, and either one can affect generic timing.
Why are there multiple patent dates?
One drug can have several patents covering different things: the active ingredient, a formulation, a manufacturing process, or a specific approved use. That is why a page may show several expiration dates instead of one simple generic date.
Built from FDA Orange Book patent and exclusivity data. Dates are refreshed from public FDA data when available; the marker is max(latest patent expiry, latest exclusivity expiry). Paragraph-IV settlements and first-filer 180-day exclusivity can shift the real date; a method-of-use patent may allow an earlier skinny-label generic for non-protected indications. Generic launch timing is an estimate, not a guarantee.
Where does this data come from?
Patents and exclusivity from the FDA Orange Book (small-molecule drugs), refreshed from public FDA data. Generic launch timing is an estimate, not a guarantee.

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

Medicare Part D (outpatient prescription) spending for Clotrimazole (matched by generic name) — the program that covers self-administered drugs. 13 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 Clotrimazole. 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 15370-220-99, 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: 15370-0220-99, written without dashes as 15370022099. 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 15370-0220-99, the first segment (15370) is the labeler code FDA assigned to Carwin Pharmaceutical Associates, LLC; the middle segment (0220) identifies this specific product — its ingredient, strength, and dosage form; and the last segment (99) 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 Carwin Pharmaceutical Associates, LLC. 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 2 pouches (15370-0220-28). 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?
Carwin Pharmaceutical Associates, LLC 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.
Do I need a prescription for this product?
This NDC is listed with FDA as a prescription product, so it is dispensed under a prescriber's order. Your pharmacist can tell you whether any over-the-counter forms of the same medication exist.
This page identifies an FDA-listed package (the NDC) and reports public regulatory and pricing data about the listing. It is reference information, not a medical recommendation — talk to your pharmacist or prescriber about your own medication.
Where does this data come from?

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 to rates in the clinical trials of another drug and may not reflect the rates observed in practice. In two randomized, placebo-controlled, phase 3 trials, 393 adult patients with otomycosis and intact tympanic membranes were treated with CLOTIC or placebo (Trial 1 and Trial 2) twice daily for a median duration of 14 days. There were 261 patients who received at least one dose of CLOTIC and 132 patients received at least one dose of placebo.

These patients had a mean age of 51 years (range 19 to 89 years); 55% were male, 87% were White, and 26% were Hispanic or Latino ethnicity. Adverse Reactions Leading to Discontinuation Treatment discontinuation due to an adverse reaction occurred in 1% (3/261) of patients receiving CLOTIC and 3% (4/132) of patients receiving placebo. Adverse reactions leading to discontinuation of CLOTIC were application site pain in two patients and tympanic membrane perforation in one patient.

Most Common Adverse Reactions Selected adverse reactions that occurred in 1 or more patients receiving CLOTIC are presented in Table 1.

👥 Use in Specific Populations ~1 min read ▾

8 USE IN SPECIFIC POPULATIONS

8.1Pregnancy Risk Summary Systemic absorption of clotrimazole following topical administration appears to be minimal, and maternal use of CLOTIC is not expected to result in fetal exposure to the drug. The background risk of major birth defects and miscarriage for the indicated population is unknown All pregnancies have a background risk of major birth defects, loss, and other adverse outcomes. The background risk in the U.S. general population of major birth defects is 2% to 4% and of miscarriage is 15% to 20% of clinically recognized pregnancies.

8.2Lactation Risk Summary Systemic absorption following topical administration of CLOTIC appears to be minimal, and breastfeeding is not expected to result in exposure of the child to CLOTIC. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for CLOTIC and any potential adverse effects on the breast-fed infant from CLOTIC or from the underlying maternal condition.

8.4Pediatric Use The safety and effectiveness of CLOTIC in pediatric patients less than 18 years of age have not been established.

8.5Geriatric Use Of the total number of patients with otomycosis who received CLOTIC in Trial 1 and Trial 2 (n=261), 78 (30%) were 65 years of age and older, while 23 (9%) were 75 years of age and older. No overall differences in safety or effectiveness were observed between subjects 65 years of age and older and younger adult patients, and other reported clinical experience has not identified differences in responses between the elderly and younger adult patients, but greater sensitivity of some older individuals cannot be ruled out.

8.5Geriatric Use Of the total number of patients with otomycosis who received CLOTIC in Trial 1 and Trial 2 (n=261), 78 (30%) were 65 years of age and older, while 23 (9%) were 75 years of age and older. No overall differences in safety or effectiveness were observed between subjects 65 years of age and older and younger adult patients, and other reported clinical experience has not identified differences in responses between the elderly and younger adult patients, but greater sensitivity of some older individuals cannot be ruled out.

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action Clotrimazole is an azole antifungal agent [see Microbiology (12.4) ] .

12.2Pharmacodynamics Clotrimazole exposure-response relationships and the time course of pharmacodynamic response are unknown.

12.3Pharmacokinetics Systemic absorption following topical administration of CLOTIC is anticipated to be minimal. The plasma concentrations of clotrimazole were not measured following otic installation of 1.7 mg (0.17 mL) clotrimazole 1% solution twice daily.

12.4Microbiology Mechanism of Action Clotrimazole, an azole antifungal agent, inhibits the cytochrome P450 dependent enzyme lanosterol 14-α-demethylase encoded by Erg11 in yeasts and Cyp51A in molds. Erg11/Cyp51A is necessary for the conversion of lanosterol to ergosterol, which is an essential sterol component of fungal cytoplasmic membrane. Disruption in ergosterol biosynthesis causes damage to the cell membrane by increasing its permeability, resulting in cell lysis and death.

Clotrimazole inhibition of lanosterol 14-α-demethylase also leads to an accumulation of 14-α-methylsterols; the methylsterols may affect the electron transport system, thereby inhibiting growth of fungi. Resistance Resistance to azoles, including clotrimazole, has been associated with decreased affinity for the target enzyme (Erg11 in Candida spp. and Cyp51A in Aspergillus spp.), increase in target copy number, alteration of the ergosterol biosynthetic pathway and overexpression of efflux pumps. Antimicrobial Activity CLOTIC has been shown to be active against most isolates of the following microorganisms both in vitro and in clinical infections [see Indications and Usage (1) ] : Fungal Aspergillus spp.

Candida spp.
