Hydroquinone + sunscreen
Therapeutic Class: SkinIndications:
Hydroquinone is indicated -
- For the gradual bleaching of hyperpigmented skin conditions such as chloasma, melasma, freckles, senile lentigines, and other unwanted areas of melanin hyperpigmentation.
- To reduce hyperpigmentation caused by photosensitization associated with inflammation or with the use of certain cosmetics.
Hydroquinone + sunscreen Cream: Each gram cream contains Hydroquinone BP 40 mg, Octyldimethyl P-aminobenzoate USP 80 mg, Dioxybenzone USP 30 mg, and Oxybenzone USP 20 mg.
Description:
Hydroquinone is a skin bleaching agent. Topical application of hydroquinone produces a reversible depigmentation of skin by inhibition of the enzymetic oxidation of tyrosine to 3,4- dihydroxyphenylalanine (DOPA) and suppression of other melanocytes metabolic processes. Exposure to sunlight or ultraviolet light will cause repigmentation of bleaching areas which may be prevented by the broad-spectrum sunscreen agents contained in the Hydroquinone + sunscreen cream.
Dosage & Administration:
Hydroquinone should be applied to the affected area and rubbed in well twice daily or as directed by a physician. Most discolorations begin to lighten after 3 or 4 weeks of treatment but it may take longer. After desired bleaching, use only as needed to maintain results of treatment. After reduction of hyperpigmentation, use of sunscreen agents and/or protective clothing should continue on bleached skin to prevent repigmentation.Use in children: Safety and efficacy in pediatric patients below the age of 12 years have not been established.
Interaction:
Peroxide: Concurrent use of peroxide may result in the transient dark staining of skin areas due to oxidation of hydroquinone.
Side Effects:
No systemic adverse reactions have been reported. Occasional hypersensitivity (localized contact dermatitis) may occur in which case the medication should be discontinued.
Precautions & Warnings:
Hydroquinone is a skin bleaching agent which may produce unwanted cosmetic effects if not used as directed. The physician should be familiar with the contents of this insert before prescribing or dispensing this medication.
Test for skin sensitivity before using by applying a small amount to an unbroken patch of skin to check in 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.
