Brief Answer:
course of 3-4 months usually helps

Detailed Answer:
In most of the cases, it is a persistent problem with recurrent attacks specially when It becomes chronic. I advice my such patients to complete a course of 3-4 months atleast of antihistaminics to control the allergy. I prefer to advise a combination of levocetrizine and montelukast in night with fexofenadine in morning. The medications are continued for 3-4 weeks followed by gradual tapering once the new lesions stop appearing. By this therapy, my most of the patients do respond. Still I would say that there are few percentage of patients who need to take antihistaminics like levocetrizine or fexofenadine once or twice a week to get symptomatic relief .
You may share my opinion with your doctor. He would advise you accordingly.
I hope it helps.
Stay healthy.
