Hello thanks for asking from HCM
Your ex partner is using heroin since last 20 years and had physically abused you. He started to take Subtex and now taking Buprex (buprenorphine). His moods are aggressive and he is showing aggression and agitated behaviour. Such type of aggression is common in
heroin addiction. Whether he is taking heroin or not can't be predicted. I would advise you to talk to him and
consult a psychiatrist for treatment. His behaviour of violence, aggression, history of physical harm to you etc could be occurring due to some mood disorder or
bipolar disorder. In bipolar disorder individual start showing aggressive behaviour and may resort to drug seeking behaviour.
Drug addiction is also a common complaint in bipolar patients.
Treatment of bipolar disorder will result in improvement of mood and he will become compliant to treatment of heroin addiction. Medicines like
Sodium Valproate, Lithium Carbonate etc can be used to reduce the aggression and his symptoms of aggression will improve. Buprenorphin (Buprenorphine Maintenance Program BMT) can be utilised for his addiction of heroin. Visit a psychiatrist for prescription of drugs.
Thanks, hope this helps you
