Some of the patients complained of nausea, head reeling, vomiting, fever and loose motion after they were injected with the anti-biotic last night.
"Sefataxin Salbuetam 1.5 gm each was administered to patients," Dr. Jatin Patnaik Additional District Medical Officer (ADMO) told reporters today.
Soon after the incident, the patients and their attendants became panicked and attacked health service staff including doctors and nurses working in the hospital which resulted an unpleasant situation there.
Drug Inspector, Kandhamal district, rushed to the scene and has seized all the injection vials from the stock in the store and some syringes used last night.
It was unexpected, accidental and perhaps due to the reaction of the injection, the ADMO opined.
