Urticaria, Dermographism: Follow-up
Updated: Feb 26, 2009
Follow-up
Further Outpatient Care
- Treat symptomatic dermographism until the problem is adequately controlled or resolved.
Prognosis
- The natural history of symptomatic dermographism is unpredictable. It may last for months or years, or be present intermittently. In many patients, the condition gradually improves and clears after several years. Symptomatic dermographism appears to have the best prognosis of the chronic urticarias in terms of clearance after 5 years (36%) and 10 years (51%) years.12
Patient Education
- Reassure patients about the benign nature of the disorder, and inform them of the possible prolonged course.
- Explain the adverse effects of antihistamines.
- For excellent patient education resources, visit eMedicine's Allergy Center and Skin, Hair, and Nails Center. Also, see eMedicine's patient education article Hives and Angioedema.
Miscellaneous
Medicolegal Pitfalls
- Dermographism can be distressing but is not life threatening. Warn patients undergoing treatment with antihistamines about drowsiness, especially when driving or handling machinery.
