It also reduces any redness, rash, pain or itchiness that may be caused in this condition. This improves your self-esteem and confidence as your appearance changes. You should always use it as prescribed to get the full benefits.

Frequently asked questions

What is Benoquin Ointment used for?

Benoquin Ointment is used only for permanent depigmentation of the skin in patients with widespread vitiligo that covers more than half of the body. It is not a cosmetic skin lightener and should never be used for freckles, melasma, or tanning spots.

Can Benoquin Ointment be used for cosmetic skin lightening?

No. Benoquin Ointment is a strong depigmenting medicine, not a mild cosmetic bleach. Using it for skin lightening in people without vitiligo can cause permanent, uneven loss of skin color.

Who should not use Benoquin Ointment?

Individuals should not use Benoquin Ointment if they are allergic to monobenzone or any of its ingredients, or if they want it only for cosmetic lightening. It is strictly for patients with extensive vitiligo.

Can Benoquin Ointment cause permanent skin changes?

Yes. Benoquin Ointment often causes irreversible depigmentation. Once the pigment is lost, your skin may remain permanently white and extra sensitive to sunlight.

What serious side effects should I watch for while using Benoquin Ointment?

You should stop using Benoquin Ointment and call your doctor if you develop severe irritation, burning, rashes, or eczema-like skin reactions. In some cases, areas far away from where the medicine was applied may also lose pigment permanently.

Does Benoquin Ointment increase sun sensitivity?

Yes. Once your skin is depigmented with Benoquin Ointment, it will remain highly sensitive to sunlight for the rest of your life. You must use sunscreen regularly and protect your skin whenever you are outdoors.

Can Benoquin Ointment affect children?

The safety of Benoquin Ointment has not been established in children under 12 years, so it should not be used in younger patients.

Can Benoquin Ointment spread its effects to areas where I do not apply it?

Yes. Even areas of normal skin far from the Benoquin Ointment application site may become depigmented. The loss of color may be irregular, excessive, unsightly, and it is often permanent.

How long does it take for Benoquin Ointment to work?

The exact time Benoquin Ointment takes to work is not known. However, depigmentation usually occurs within one to four months of treatment. If there is no improvement after four months, your doctor may stop the treatment.
