What is coal tar?

Coal tar is a by-product of coal processing.

Psoriasin (for the skin) is used to treat the skin symptoms of psoriasis, including dryness, redness, flaking, scaling, and itching. Coal tar is not a cure for psoriasis, and it will provide only temporary relief of skin symptoms.

Coal tar may also be used for purposes not listed in this medication guide.

Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.

Before taking this medicine

You should not use Psoriasin if you are allergic to coal tar.

Ask a doctor or pharmacist if it is safe for you to use this medicine if you have other medical conditions, especially:

Coal tar products may contain lanolin, mineral oil, or other emulsifiers. Check the label of any coal tar product you are using. Talk with your doctor before using coal tar if you are allergic to any of the ingredients.

Ask a doctor before using this medicine if you are pregnant or breast-feeding.

Do not allow a young child to use this medicine without adult supervision.

How should I use coal tar?

Use exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended.

Apply coal tar cream, lotion, ointment, or solution according to the directions on the medication label. Some forms of coal tar may be applied 1 to 4 times per day.

To use coal tar bath oil, pour 1 to 3 capfuls into a warm bath before bathing. The oil can make the bathtub slippery. Take care to avoid a fall.

Shake the coal tar shampoo well just before each use. Use enough shampoo to create a rich lather. Massage the shampoo into your scalp and rinse thoroughly. Apply the shampoo a second time and leave it on your scalp for 5 minutes. Rinse thoroughly.

Coal tar shampoo may discolor blond or colored hair. This effect is usually temporary.

Do not use coal tar to treat large skin areas. Do not use coal tar over long periods of time without your doctor's advice.

Some forms of coal tar can stain fabric or other surfaces.

Call your doctor if your symptoms do not improve, or if they get worse while using Psoriasin.

Store at room temperature away from moisture and heat. Keep the medicine tightly closed when not in use.

What happens if I miss a dose?

Since Psoriasin is used when needed, you may not be on a dosing schedule. If you are on a schedule, use the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not use extra medicine to make up the missed dose.

What happens if I overdose?

An overdose of Psoriasin is not expected to be dangerous. Seek emergency medical attention or call the Poison Help line at 1-800-222-1222 if anyone has accidentally swallowed the medication.

What should I avoid while using coal tar?

Do not use coal tar together with other psoriasis medications unless your doctor tells you to.

Avoid getting Psoriasin in your eyes. If this does occur, rinse with water.

Do not use coal tar to treat the skin of your groin or rectal area.

Avoid exposure to sunlight or artificial UV rays (sunlamps or tanning beds). Coal tar can make your skin more sensitive to sunlight and sunburn may result.

What other drugs will affect coal tar?

It is not likely that other drugs you take orally or inject will have an effect on topically applied coal tar. But many drugs can interact with each other. Tell each of your health care providers about all medicines you use, including prescription and over-the-counter medicines, vitamins, and herbal products.

Popular FAQ

How does Ilumya work to treat psoriasis?

Ilumya works by binding selectively to interleukin-23 (IL-23) which is a naturally occurring cytokine. IL-23 plays a key role in promoting inflammation and regulating other cytokines (such as IL-17) and inflammatory substances, such as TNF-α3-7. By blocking the effects of IL-23, Ilumya helps control the release of IL-17 and TNF-α, which reduces inflammation associated with psoriasis. It also decreases how many inflammatory cells are present within psoriatic lesions, helps prevent plaque formation, and resolves tissue damage. Continue reading
