Coal tar is an old over-the-counter remedy for the itching, scaling and flaking of psoriasis, seborrheic dermatitis (a flaky, itchy skin and scalp condition) and dandruff, working by slowing the buildup of skin cells, and dozens of makers sell it under brand and store names. Most people tolerate it well, though the strong smell and its habit of staining clothes, bedding and very light hair are what users notice most. The thing to watch is sunburn, because treated skin burns more easily for up to 24 hours after you apply it. Keep it off your eyes and broken skin, and see a doctor if it fails to help.
Clinical pearls
- Let a coal tar shampoo sit on the scalp for several minutes before rinsing, because a quick lather does little.
- If you have very light hair, try Psoriasin products on a few strands first, since they can change the color.
- Do not stack it with ultraviolet light therapy or prescription psoriasis drugs unless the prescriber running that treatment agrees.
- Psoriasis covering a large area of your body needs a doctor's input before you spread coal tar over it.

How widely Coal Tar is used (Medicaid data)
A general measure of how commonly Coal Tar is prescribed, based on Medicaid — one of the largest public drug programs. The figure below is prescriptions filled in Q1–Q4 2025, summed across every form and brand of the drug.
Think of this as a proxy for how widely Coal Tar is used, drawn from freely available public data. Medicaid is just one program — these numbers don’t include Medicare, other government coverage, or commercial and cash-pay prescriptions, so real-world use is higher than what’s shown here.
How commonly is Coal Tar prescribed? Of the 1,601 medications we measure, Coal Tar ranks #1,452 by Medicaid prescriptions — more than 9% of them.
Utilization by Coal Tar product
Pick a product to see its own Medicaid numbers. Each chip is one clinical product — a specific strength & dosage form as defined by RxNorm — with brand-name and generic versions combined.

Shares are of the Medicaid prescriptions shown here. Product grouping follows RxNorm (the National Library of Medicine’s drug terminology), so “one product” means one strength & dosage form regardless of manufacturer. Dollar figures are gross Medicaid reimbursement before mandatory rebates — rebates (often large, especially for brand-name drugs) are confidential, so actual net cost to Medicaid is lower than shown.

A general popularity signal; it excludes Medicare, commercial insurance and cash prescriptions, so it is not total U.S. use. Based on the 2 of 46 listed Coal Tar NDCs with Medicaid activity.
Compare Coal Tar products
A representative set of FDA-listed product records for Coal Tar — across manufacturers, strengths, and dosage forms, grouped by form with each product’s manufacturer and how the FDA approved it. The same medicine may be made and packaged by different companies, so a single drug can have many directory entries. (It’s also why a refill can look different — a new shape, color, or box — even though it contains the same medication.)

Coal Tar side effects reported to the FDA (FAERS)
After a medicine reaches the market, patients, doctors and drugmakers can send the FDA reports of problems they think may be linked to it. Here’s what’s been reported for Coal Tar — a signal of what to watch for, not proof the drug caused it.
Source: openFDA, from the FDA Adverse Event Reporting System (FAERS). These are voluntary reports — they don’t prove the drug caused the effect, and counts reflect how often something was reported, not how often it actually happens. Reports also often name the very problem the medicine is taken for — a common reason to file one is that the drug didn’t help — so for a pain reliever you may see “pain” high on the list; that points to why the report was filed, not to the drug causing the symptom. This counts every report that lists Coal Tar in any role, so the total runs higher than the FDA’s official dashboard, which counts only cases where the drug is the suspect. For the authoritative figures, see the FDA FAERS Public Dashboard. Always talk to your pharmacist or doctor.
