Monobenzone is used to treat the uneven appearance of the skin due to a loss of skin color (vitiligo). It works by permanently removing color from normal skin located around skin with vitiligo. This will help to make the appearance of the skin more even.
Do not use this drug to treat other skin discoloration problems ("sun spots," "age spots," freckles, skin discoloration caused by hormone medicine, perfumes, pregnancy, or skin trauma). Monobenzone is not a mild cosmetic bleach. Because it causes a permanent discoloration of the skin, it may not be the right treatment for these other skin conditions.
This medication is for use on the skin only. Apply a thin layer of the medication to normal-colored skin, usually 2-3 times daily or as directed by your doctor. Avoid getting this product in your eyes or on the inside of your nose or mouth. If you do get this medication in those areas, flush with plenty of water.
After using this medication, the skin will be permanently affected and sensitive to sunlight. Avoid prolonged exposure to sunlight, tanning booths, and sunlamps. Always use a sunscreen of SPF 15 or greater, and wear protective clothing when outdoors.
It may take up to 4 months before the full benefit of this drug takes effect. Once the desired skin color is achieved, this medication is applied only as needed to maintain your new skin color (usually 2 times a week).
Use this medication regularly to get the most benefit from it. To help you remember, use it at the same times each day.
Inform your doctor if your condition persists or worsens after 4 months.
Mild burning, irritation, redness, cracking, or peeling of the treated skin may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.
Skin that is not treated with this medication may also become discolored or irregular in appearance. Sometimes these effects may be permanent. Ask your doctor or pharmacist for more details.
