Side effects
Hydroquinone cream is very well tolerated. Some women may experience minor and temporary skin irritations including mild itching or stinging and reddening of the skin (irritant contact dermatitis). If these do not subside stop using the cream.
Side effects that should warrant stopping the cream and seeking medical advice immediately include severe burning, itching, crusting, or swelling of treated areas (possible allergic contact dermatitis) and any unusual skin discolouration.
Prolonged use of hydroquinone has been associated with the development of exogenous ochronosis (a persistent blue-black pigmentation), especially in Africa, but this is rare. It might be due to other ingredients such as phenol, resorcinol and antimalarial agents, which are known to cause ochronosis.
Precautions
Do not use benzoyl peroxide, hydrogen peroxide, or other peroxide products when using hydroquinone. A temporary dark staining of the skin may occur. If accidentally used together, wash the skin with soap and water to remove the staining.
Hydroquinone creams may contain sodium metabisulphite that may cause serious allergic reactions (including anaphylaxis) in certain susceptible people.
Hydroquinone should not be used in pregnancy or when breastfeeding.
