Hello and welcome to Healthcare Magic. Thanks for your query.
It is stressful for anyone to see a family member go through a difficult time and I appreciate your concern for your brother's well-being. Now, Spasmo-Proxyvon is an opiod drug which is not only addictive but can also have many potential psychiatric effects. Moreover, your brother's mood fluctuations, instabilities and erratic behaviour seem to be indicative of a mood disorder
(which may be the reason why his psychiatrist
had started him on mood stabilizer
and anti-psychotic medication
). So, an underlying mood disorder complicated by the psychiatric effects of the Spasmo-Proxyvon could be causing him to have such aggressive behaviour after a few hours of its intake.
There are effective treatment methods which can help your brother come out of this addiction. But remember, that this requires motivation and sincere efforts from his side also. Treatment is in the form of medication as well as counselling
/ behavioural therapies. For example, motivational enhancement therapy, relapse prevention strategies, etc. are effective techniques used to improve his motivation and help him quit the drug. Please encourage him to have regular follow-up and therapy sessions with his psychiatrist.
