Quick answers
  • RxCUI (RxNorm): 415978
Why two NDCs? The FDA registers this code as 52389-166-43 — 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 → 52389-0166-43. Same drug, same package — only the format differs.

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.

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.

🧪 Avoiding an ingredient? See Coal Tar inactive ingredients by manufacturer: every current product's list side by side, so you can ask your pharmacy for the version that does not list it.

We could not link this NDC to a current FDA Structured Product Label. An inactive-ingredient list is therefore not available from this source.
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.

Package Insert Psoriasin DAYTIME RELIEF VANISHING GEL DERMATOLOGIST RECOMMENDED Stops Psoriasis itching, scaling, redness Can complement topical steroids Dries quickly, low odor Visible results in just days Helps prevent recurrence Psoriasin Daytime Relief Vanishing Gel gets to work quickly to help stop the itching, flaking, redness and related discomforts associated with psoriasis. Formulated in a vanishing gel base with aloe and vitamin E, it applies easily, dries quickly and absorbs thoroughly, leaving no greasy appearance or lingering odor.

Use Psoriasin Daytime Relief Vanishing Gel with confidence to relieve symptoms of psoriasis and help restore you skin to a more natural looking appearance. How Coal Tar Works The coal tar in Psoriasin Daytime Relief Vanishing Gel slows down the excessive skin cell production that is the root cause of psoriasis symptoms. No other FDA compliant non-prescription drug ingredient works this way.

Slowing excesive skin cell production means it can help reduce the itching, scaling and redness of psoriasis. With regular use as directed, Psoriasin Daytime Relief Vanishing Gel can even help prevent recurrence of psoriasis symptoms. And coal tar can be used to complement topical steroid therapies.

The Role of Topical Steroids Topical steroids - similar to the natural corticosteroid hormones produced by the adrenal glands - are a frequently used psoriasis symptom treatment. Topical steroids are used as anti-inflammatory agents to reduce the swelling and redness of lesions. Although topical steroids can produce rapid symptom relief, continuous use of them may cause potential side effects such as skin thinning.

Topical Therapy Choices for Psoriasis Symptom Control Due to the well documented side effects of topical steroids, some experts recommend using intermittent therapy (also called weekend or pulse therapy). This type of treatment involves applying a topical steroid for three consecutive days each week followed by four days of a coal tar medication like Psoriasin Daytime Relief Vanishing Gel . Ask your doctor if this approach might be right for you.

PSORIASIS SELF-CARE TIPS In addition to psoriasis treatments recommended by a doctor, you can help reduce psoriasis symptoms by using self-care approaches, including: Keep Skin Moisturized Using a moisturizer is an important part of self-care for psoriasis. Dry skin makes irritation and itching caused by psoriasis worse than it needs to be. A vicious cycle can result: dry skin can cause itching and scratching, leading to new psoriasis patches developing on the irritated skin.

Dermatologists recommend ointments and heavy creams to lock water into the skin. Bathe with Care Too many baths and showers can dry your skin. Here are a few suggestions: Don't bathe or shower with hot water, which can irritate.

Use lukewarm water instead. Don't dry off by rubbing with a towel. Pat yourself somewhat dry and then apply cream.

Plain water can dry your skin. Adding salts, oil, or finely ground oatmeal to bath water can help to soothe your skin. Take fewer showers and baths.

They can strip your skin of natural oils. Bathe every other day or every third day, especially during the winter months. Reduce Stress Stress can cause psoriasis to flare for the first time or aggravate existing psoriasis.

Relaxation and stress reduction may help prevent stress from making your psoriasis symptoms worse. Engage in relaxation techniques, such as yoga, meditation, or massage Excercise regularly Get enough sleep Be Smart About Sunlight The ultraviolet rays in sunlight slow the growth of skin cells, so getting moderate doses of sun is good. But make it brief and use sunscreen, because sunburn can trigger psoriasis flare-ups.

Some medications can make your skin more sensitive to ultraviolet rays, so talk to your doctor first. Stick to the Plan Applying creams and ointments day after day can be inconvenient. But compliance is the key for topical therapies.

Once you have a topical treatme… [Excerpted — this section continues on DailyMed.]

Questions about this listing

Is this NDC FDA-approved?
An NDC listing does not by itself establish FDA approval — the NDC Directory records that a product is listed with FDA, not that it was reviewed and approved. This listing's marketing category is "Otc Monograph Drug". Products approved under an application carry an NDA, ANDA, or BLA number.
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.
What does the discontinued status mean for this NDC?
The labeler reported a marketing end date (or the listing was delisted), so this specific package is no longer actively marketed. Remaining stock may still be dispensed for a time, and the NDC stays valid for historical records and claims — but data feeds (pricing, labeling) typically stop updating for it. Other package sizes or other manufacturers' versions of the same medication may still be marketed — see the equivalents section where available.
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.
Does this product come in other package sizes?
Yes — the FDA directory lists 3 other package presentations of this same product, including 1 tube (52389-0166-01), 1 tube (52389-0166-57), 2 tubes (52389-0166-56). 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?
Kobayashi Healthcare International, 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.
Do I need a prescription for this product?
This NDC is listed with FDA as an over-the-counter product, so it does not require a prescription. Follow the package directions, and ask your pharmacist if you are unsure whether it is right for you.
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?
Listing facts (marketing category, packager status, marketing dates) from the FDA openFDA NDC Directory; label availability from DailyMed; pricing coverage from CMS NADAC; equivalence scope from the FDA Orange Book.
