Which drug is more effective for itchy skin: Clatra or Delortan?

The preparations listed in the question belong to the antihistamines of the second generation - Clatra and the third generation - Delortan. Unlike second-generation antihistamines, the third generation is characterized by a better therapeutic profile and fewer side effects, but the antihistamine effect is at a similar level. With exacerbation of allergic symptoms of allergic disease, it is often required to increase the dose of an antihistamine drug (in the treatment of chronic urticaria, doses up to 4 times higher than recommended as standard are used), it is also permissible to take antihistamines with different chemical structure. It is difficult for an outsider to assess whether such a procedure is necessary in Pai case. I encourage you to consult your doctor. Please do not change the dosage on your own.
