Is Levo Syrup And Lidocam Tablet Advisable For Inhalation Of Bleaching Powder Fumes?

My wife Mrs Uma inhaled bleaching powder fumes in bath room. A week back incident now she is having cough and I took her to our Doctor who has given Ambrolyte Levo syrup, Lidocam Tablet and Criz M tablet for 3 days. He said the lungs are normal. Please inform me whether I am correct in the process of treatment or shall I take her to a Specialist.
