This patient support community is for discussions relating to undiagnosed symptoms, breathing difficulties, feeling cold, cough, diarrhea, dizziness, fainting, fever, indigestion, itching, nausea, numbness, pain (chronic), paralysis, rash, sweating, swelling, urination problems, and vomiting.
'The primary subgroups of chronic urticaria include physical urticaria (ie, symptomatic dermatographism, cholinergic urticaria, pressure urticaria), urticaria secondary to an underlying medical condition, and chronic idiopathic urticaria (CIU).'
Avoidance of mental stress, overtiredness, alcohol, nonsteroidal anti-inflammatory drugs, and tight-fitting garments is recommended. Nocturnal pruritus may be reduced by lukewarm bathing and keeping the ambient temperature of the bedroom cool. Application of lotions with menthol and phenol (Sarna) provide prompt relief of pruritus for some patients.
Nonsedating antihistamines remain the mainstay of treatment. Many patients find pruritus less troublesome during the daytime, with pruritus maximized at night when there are fewer distractions. An additional nocturnal dose of a sedative antihistamine such as hydroxyzine or doxepin may be added to the morning dose of a low-sedation anti-H1 antihistamine. Doxepin should not be used in patients with glaucoma and should be used with extreme caution in elderly patients or those with heart disease. Doubling the labeled dose of low-sedating antihistamines may benefit some patients, and increasing the dose of these antihistamines is often the safest therapeutic approach for patients who do not have an adequate response to the conventional dose of these medications.
Patients who respond poorly to antihistamine therapy or who are known to have urticaria in which the inflammatory infiltrate is neutrophil predominant may require the addition of colchicine (0.6 mg twice daily) or dapsone (50-150 mg once daily) to the treatment regimen (except patients with glucose-6-phosphate dehydrogenase [G-6-PD] deficiency). Patients with autoimmune urticaria may benefit from methotrexate or cyclosporine.'
A consultation with an allergist is recommended.
