My father, 65 years old, had problems of loose-motion and vomiting 2 days ago. The doctor at the hospital administered Monocef and Metronidazole through I.V. Yesterday, we brought him home as he felt okay. The doctor had prescribed the below medicine to be used at home: O2 : 1-0-1 Nexpro RD 40mg : 1-0-1 Vibact : - 1 - Today morning, we couldn t get Nexpro at the medical shop nearby, so we gave only O2. Now he is continuously feeling like vomiting due to stickiness in his throat. Should we give him Nexpro RD 40mg now that we got it from the medical shop to reduce his trouble?
