My father 57 years old had accident and suffered head injury. After ct scan found he had subarachnoid hemorrhage. He was in hospital for 10 days. After some days of discharge from hospital he started showing aggression and verbal abuse. He use to sleep for only 1 or 2 hours in 24 hours. Doctor prescribed qutan sr100 in night and qutan sr50 in day. After giving qutan sr100 in night he was like he is unconscious and even after trying to wake him up he was sleepy and did not woke up. Should we reduce the dosage of qutan sr 50?
