How does this medication work? What will it do for me?
Doxepin cream belongs to the class of medications called topical anti-pruritics (anti-itch). It is used for the short term relief of moderately severe itching caused by conditions such as eczema. Doxepin cream works to block the action of histamine, which is produced when tissue is irritated, such as in an allergic reaction, resulting in the itching sensation.
