What Is Erythema Multiforme?
9. Management According to the Cause
There are some differences in treatment approaches for erythema multiforme caused by infection rather than medication. When an infection is determined to be the trigger, treating this underlying issue may be necessary to clear the condition. If the herpes simplex virus is the cause, then it is necessary to treat the virus to prevent recurrences of erythema multiforme. However, note that treating the HSV infection after the appearance of the rash will not alter the course of the condition.
When the doctor determines that medication is the cause for the disorder, it may be necessary to determine which drug is precipitating the reaction if the individual is taking more than one. In this case, discontinuing the use of the medication responsible might be necessary.
