Most addiction treatments, especially drug addiction treatment, include a period of residential treatment. This is the period where the person is put into rehab treatment that includes close monitoring and medication.
This period may last from a few days to a few weeks depending upon how severe the addiction is. After that, there will be a period of inpatient monitoring of the patient, and then they will be discharged from the treatment center.But you must not think that this is the end of the treatment. Far from that! Actually, any addiction treatment continues for life. You, as a responsible family member, have to provide all the intervention you can to help this ongoing treatment.
One of your responsibilities will be to monitor whether the person is having a relapse or not. This will be just like the withdrawal symptoms the person had earlier during the treatment program, but on a milder note. Some family members tend to provide the addictive substance to the patient when the relapse occurs, thus destroying the very core of the treatment. What you must actually do when the relapse happens is to notify the treatment center or a nearby physician so that you can understand the right course of action. The best way out is to get educated on a possible relapse right in the beginning so that it is not too late when it actually happens.
You will also need to accompany the person to the treatment center at least on a fortnightly basis to follow up on the treatment. They will check if there is a possibility of a relapse happening, and if yes, they will alter their treatment modes.
Most importantly, you need to be loving and caring towards the person. Addiction is just like any other disease, and it requires just as much tender loving care from close family and friends.
