Description

Urea 40% is a keratolytic emollient which is a gentle, yet potent, tissue softener for nails and/or skin.  Each gram of Urea 40% contains 40% urea as an active ingredient, and the following inactive ingredients:  Carbomer, Dimethyl Isosorbide, Emulsifying Wax, Glycerin, Isopropyl Myristate, Neopentyl Glycol Dicaprylate/Dicaprate, Purified Water, Sodium Hydroxide, Tridecyl Stearate, Tridecyl Trimellitate, and Xanthan Gum.

Urea is a diamide of carbonic acid with the following chemical structure:

Clinical Pharmacology

Urea gently dissolves the intracellular matrix, which results in loosening of the horny layer of the skin and shedding of scaly skin at regular intervals, thereby softening hyperkeratotic areas of the skin.

Pharmacokinetics

The mechanism of action of topically applied urea is not yet known.

Indications and Usage

For debridement and promotion of normal healing of hyperkeratotic surface lesions, particularly where healing is retarded by local infection, necrotic tissue, fibrinous or purulent debris or eshar.  Urea is useful for the treatment of hyperkeratotic conditions such as dry, rough skin, dermatitis, psoriasis, xerosis, ichthyosis, eczema, keratosis pilaris, keratosis palmaris, keratoderma, corns and calluses, as well as damaged, ingrown and devitalized nails.

Contraindications

Known hypersensitivity to any of the listed ingredients.

Warnings

For topical use only.  Avoid contact with eyes, lips or mucous membranes.

Precautions

This medication is to be used as directed by a physician and should not be used to treat any condition other than that for which it was prescribed.  If redness or irritation occurs, discontinue use and consult a physician.

PREGNANACY:  P regnancy Category B.  Animal reproduction studies have revealed no evidence of harm to the fetus, however, there are no adequate and well-controlled studies in pregnant women.  Because animal reproductive studies are not always predictive of human response, Urea 40% should be given to a pregnant woman only if clearly needed.

NURSING MOTHERS:   It is not known whether or not this drug is excreted in human milk.  Because many drugs are excreted in human milk, caution should be exercised when Urea 40% is administered to a nursing woman.

Adverse Reactions

Transient stinging, burning, itching or irritation may occur and normally disappear upon discontinuing the medication.

Dosage and Administration

Apply Urea 40% to affected skin twice a day, or as directed by your physician.  Rub in until completely absorbed.
