I suffered with sudden hives all over the body with severe itching a day ago took medicine (levocetirizine and another medicine of lybrate pharmaceuticals,(name is but cut)) yesterday morning and evening felt fine whole day. Today I didn't took medicine and again the same itching and hives started occurring, never suffered from such kind of issues. Upto how many days shall these medicines shall be continued? As I purchased medicine from a chemist shop, shall I visit doctor? Or continue to take medicine? Kindly suggest. Thank you.
