Mode of actions
Hydroquinone is a topical depigmentating agent used in hyperpigmentation conditions by suppressing melanocyte metabolic processes. It also increases melanin excretion from melanocytes and prevents its production.
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 4 weeks of treatment but it may take longer. After desired bleaching, use only as needed to maintain results of treatment. Hydroquinone bleaching is faster, more dependable and easier if the treated area is protected from ultraviolet light. Therefore, exposure to sunlight should be minimized at the period of treatment. During day, an effective broad-spectrum sunscreen should be used, unnecessary solar exposure should be avoided and protective clothing should be used to prevent repigmentation of treated areas. After reduction of hyperpigmentation, use of sunscreen agents and/or protective clothing should continue.Use in children: Safety and efficacy in paediatric patients below the age of 12 years have not been established.
Pregnancy & Lactation
Animal reproduction studies have shown an adverse effect on the fetus and there are no adequate and well-controlled studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks
