Doxepin Medication to Treat Allergies & Eczema

This medication is thought to work by blocking the action of histamine, a body chemical that is involved in generating allergic reactions. When histamine is blocked, the itching and irritation associated with allergic eczema also ceases.

About Doxepin for Allergies

When used for the treatment of eczema, doxepin is prescribed and used as a topical skin cream. Most people who are prescribed doxepin for allergies such as eczema will use the cream three or four times a day. It’s important to use the cream consistently, at the same times each day, to ensure a regular dosage of the active ingredient.

To use doxepin, the skin should first be washed and dried. Next, apply a small amount of cream to the affected area, and massage it into the skin. When this is finished, the hands should be washed before touching any other part of the skin. Doxepin should not be applied around the eyes or mouth.

To use doxepin safely, several restrictions should be followed.

• The medication should not be used any more or any less than prescribed.
