FULL PRESCRIBING INFORMATION

DESCRIPTION

HYDRO 35 is a keratolytic emollient in a water and lipid based foam containing lactic acid which is a gentle, but potent, tissue softener for skin and nails. Each gram of HYDRO 35 contains Urea 35% as the active ingredient, and the following inactive ingredients: dimethicone, ethylparaben, glycerin, lactic acid, methylparaben, phenoxyethanol, polysorbate 20, povidone, propylene glycol, propylparaben, purified water, stearic acid, trolamine, and in propellants butane and propane.

CHEMICAL STRUCTURE

Urea has the following chemical structure:

CLINICAL PHARMACOLOGY

Topically applied urea dissolves the intercellular matrix of the skin which results in enhanced shedding of scaly, dry skin and thus a softening of the hyperkeratotic areas of the skin.

Urea topically applied to the nail plate has a similar effect on the intercellular matrix of the nail plate.

PHARMACOKINETICS

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

INDICATIONS AND USAGE

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

CONTRAINDICATIONS

Known hypersensitivity to any of the listed ingredients.

WARNINGS

HYDRO 35 is for external use only. It is not for ophthalmic, oral, anal or intravaginal use. Contact with eyes, lips and all mucous membranes should be avoided. HYDRO 35 should not be used by persons who have a known hypersensitivity to urea or any of the other listed ingredients.

PRECAUTIONS

HYDRO 35 should be used only as directed by a physician and should not be used to treat any condition other than that for which it is prescribed. If redness or irritation occurs, discontinue use and consult with prescribing physician.

Pregnancy (Category B) - Animal reproduction studies have not been performed with topically applied urea and it is not known whether HYDRO 35 can cause fetal harm when administered to a pregnant woman. Nevertheless, HYDRO 35 should be used by a pregnant woman only if necessary.

Nursing Mothers - It is not known whether topically applied urea is excreted in human milk. Due to the fact that many drugs are excreted in human milk, caution should be exercised by physicians when administering HYDRO 35 to nursing mothers.

KEEP THIS AND ALL OTHER MEDICATIONS OUT OF THE REACH OF CHILDREN.

ADVERSE REACTIONS
