After what time will he feel better taking Naltex?

Good morning, the drug Naltex contains in its composition naltrexone, which primarily has a blocking effect on opioid receptors. Indications for the use of the drug are the prevention of recurrence of addiction in people addicted to opioids and the treatment of alcohol addiction. I would like to emphasize that the drug is introduced as a complement to comprehensive treatment, which includes, among others, psychological care or behavioral therapy. Treatment of addiction in each person proceeds in a different, individual way. For these reasons, it is impossible to clearly determine either the time of use of the drug, although we are always talking about several months of therapy, or the time after which the patient will feel a clear improvement.
