[|Human|] My Father in law had recently undergone a complete knee replacement for right leg and had a past history of Coronory Bypass as well in the year 2000 and takes medicines for the same. As he was not able to sleep during the night, he had been suggested Nervmax capsules one at the time of sleeping. He has already been taking alprex for a long time now. However, even after taking 1 capsule, he has not been able to sleep. Please advise if he should continue using Nervmax and the side effects of using the same.
[|AI|]  HiI understand your concern. Sleep disturbance is common in post-operative period and Generally in old age. Due to history of past coronary surgery choice of medicines should be cardio safe Chat Doctor. Lorazepam 1 mg is ideal choice in cardiac patients. Sleep disturbance in old age can be treated with lorazepam 1 mg or 2 mg but dose is depend upon age and renal/liver function. Nervmax is pregabalin it is not a choice as a sleep remedy it is neuroprotective. Besides this following will helpful. Avoid smoking or alcohol. Avoid tea or coffee before getting sleep. Fix time schedule for sleep. No day time sleep. Treatment of underlying psychological stress is must if any. Still have query then feel free to ask. Thank you.
