Reviews

Many patients believe that before the start of therapy, the description of the Hydrea tool, the instruction, should be studied. Photos before and after therapy can also be viewed. Judging by the reviews, people prefer to be treated only under medical supervision and do not risk self-treatment, as it is dangerous, they drink a lot of fluids. If the medication is not combined with radiotherapy, side effects either appear( in cases when previously absent), or become even more pronounced. But this does not always happen.
