Full prescribing information FDA SPL
🎯 Indications and Usage ▾
INDICATIONS AND USAGE HYDROQUINONE USP, 4% SKIN BLEACHING CREAM is indicated for the gradual bleaching of hyperpigmented skin conditions such as chloasma, melasma, freckles, senile lentigines, and other unwanted areas of melanin hyperpigmentation.
⏱️ Dosage and Administration ▾
DOSAGE AND ADMINISTRATION HYDROQUINONE USP, 4% SKIN BLEACHING CREAM should be applied to affected areas and rubbed in well twice daily, in the morning and before bedtime, or as directed by a physician. If no improvement is seen after 2 months of treatment, use of this product should be discontinued. There is no recommended dosage for pediatric patients under 12 years of age except under the advice and supervision of a physician.
⛔ Contraindications ▾
CONTRAINDICATIONS Prior history of sensitivity or allergic reaction to hydroquinone or to any of the ingredients of the product. The safety of topical hydroquinone use during pregnancy or for children (12 years and under) has not been established.
⚠️ Warnings ▾
WARNINGS Contains sodium metabisulfite, a sulfite that may cause allergic-type reactions including anaphylactic symptoms and life-threatening or less severe asthmatic episodes in certain susceptible people. The overall prevalence of sulfite sensitivity in the general population is unknown and probably low. Sulfite sensitivity is seen more frequently in asthmatic than in non-asthmatic people.
Since this product contains no sunscreen, an effective broad spectrum sun blocking agent should be used and unnecessary solar exposure avoided, or protective clothing should be worn to cover bleached skin in order to prevent repigmentation from occurring. Hydroquinone may produce exogenous ochronosis, a gradual blue-black darkening of the skin. If this condition occurs, discontinue treatment and consult your physician.
The majority of patients developing this condition are Black, but it may also occur in Caucasians and Hispanics.
🤒 Adverse Reactions ▾
ADVERSE REACTIONS The following adverse reactions have been reported: dryness and fissuring of paranasal and infraorbital areas, erythema, and stinging. Occasional hypersensitivity (localized contact dermatitis) may develop. If this occurs, the medication should be discontinued and the physician notified immediately.
🔄 Drug Interactions ▾
Drug Interactions Patients are cautioned on concomitant use of medications that are known to be photosensitizing.
🤰 Pregnancy ▾
Pregnancy Teratogenic Effects Pregnancy Category C Animal reproduction studies have not been conducted with topical hydroquinone. It is also not known whether topical hydroquinone can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Topical hydroquinone should be given to a pregnant woman only if clearly needed.
🧒 Pediatric Use ▾
Pediatric Use Safety and effectiveness for pediatric patients below the age of 12 years have not been established.
🆘 Overdosage ▾
OVERDOSAGE There have been no systemic reactions reported from the use of topical hydroquinone. However, treatment should be limited to relatively small areas of the body at one time, since some patients experience a transient skin reddening and a mild burning sensation which does not preclude treatment.
🧬 Clinical Pharmacology ▾
CLINICAL PHARMACOLOGY Topical application of hydroquinone produces a reversible depigmentation of the skin by inhibition of the enzymatic oxidation of tyrosine to 3,4-dihydroxyphenylalanine (dopa) (Denton, C. et al., 1952) 1 and suppression of other melanocyte metabolic processes (Jimbow, K. et al., 1974) 2 . Exposure to sunlight or ultraviolet light will cause repigmentation of bleached areas (Parrish, J.A. et al., 1978) 3 .
📦 How Supplied / Storage and Handling ▾
HOW SUPPLIED HYDROQUINONE USP, 4% SKIN BLEACHING CREAM is available in a 1 oz (28.35 g) tube with (NDC 10135-0724-99) Store at 20°C-25°C (68°F-77°F) [see USP Controlled Room Temperature].

💬 Information for Patients ▾
Information for Patients Sunscreen use is an essential aspect of hydroquinone therapy because even minimal sunlight sustains melanocytic activity. To prevent repigmentation, during treatment and maintenance therapy, sun exposure on treated skin should be avoided by application of a broad spectrum sunscreen (SPF 15 or greater) or by use of protective clothing. Avoid contact with eyes and mucous membranes.
Keep this and all medications out of reach of children. In case of accidental ingestion, call a physician or a poison control center immediately.
⚠️ Precautions ▾
PRECAUTIONS (see WARNINGS ) General Test for skin sensitivity before using by applying a small amount to an unbroken patch of skin; check within 24 hours. Minor redness is not a contraindication, but where there is itching or vesicle formation or excessive inflammatory response further treatment is not advised. Close patient supervision is recommended.

About this NDC listing & data coverage
Listed without an FDA application
This product's marketing category indicates it is marketed without an approved FDA application (no NDA, ANDA, or BLA on file). Having an NDC does not by itself establish FDA approval — the NDC Directory is a listing system, not an approval decision. Approval-linked data such as Orange Book therapeutic-equivalence ratings therefore does not apply.
