What do you understand by dermatitis medicamentosa?

Under this head are included all eruptions due to the ingestion or absorption of certain drugs.

In rare instances one dose will have such effect; commonly, however, it results only after several days' or weeks' continued administration. With some drugs such effect is the rule, with others it is exceptional, nor are all individuals equally susceptible.

How is the eruption produced in dermatitis medicamentosa?

In some instances it is probably due to the elimination of the drug through the cutaneous structures; in others, to the action of the drug upon the nervous system. The view that the drug acts as a toxin or generates some toxin or irritant material in the blood, to which the eruptive phenomena may be due, has also been advanced.
