Define the plan around the person's actual risks
List the substances, past overdose or withdrawal, co-occurring conditions, medication, housing, relationships, work, and settings linked with renewed use. Avoid copying a generic worksheet that treats every trigger as identical. A clinician can help prioritize which risks need medical action and which can be managed with routine coping. The patient should understand and help write the plan so it remains usable outside treatment; include the settings and transitions where earlier plans failed so prevention addresses real patterns rather than ideal conditions.
Separate early warning signs from immediate danger
Early signs may include missed appointments, isolation, sleep change, romanticizing past use, stopping medication, or returning to high-risk places. Immediate danger includes overdose, severe withdrawal, suicidal behavior, psychosis, seizure, chest pain, or inability to remain safe. Give each category a different response. Clear thresholds reduce delay when a supporter is unsure whether to call the clinician, 988, or 911; supporters should understand the thresholds and keep crisis information accessible instead of debating severity during an emergency.
Map external and internal triggers
External triggers can include people, places, substances, paydays, celebrations, or times of day. Internal triggers may involve craving, pain, anger, loneliness, excitement, shame, or physical sensations. Note which triggers can be avoided temporarily and which require practiced coping. Review the list after real events because the most important pattern may not be obvious during residential treatment; rank the triggers by frequency, danger, and ability to change so limited energy goes first to the highest risks.
Match each common trigger with more than one response
A useful plan can include leaving the setting, calling someone, attending a visit, delaying a decision, eating, resting, exercising safely, or using a therapy skill. One coping method may be unavailable or ineffective on a difficult day. Put phone numbers and locations beside the strategy. Practice simple responses before high-risk situations rather than expecting perfect recall during intense craving; each response should name a place, person, number, or activity that is genuinely available at the likely time.
Medication and appointments belong in prevention
List current medication, prescribers, refill dates, pharmacy, transportation, and what to do after a missed dose. Medication for opioid or alcohol use disorder can be a central protective treatment rather than a backup after relapse. Book follow-up before discharge. The plan should explain how to reconnect rapidly if attendance drops without requiring the person to begin the entire admissions process again; backup prescriber and pharmacy information can reduce interruption during weekends, travel, insurance changes, or an unexpected closure.
Overdose prevention is required even with an abstinence goal
Reduced tolerance can make a return to opioid use especially dangerous, and fentanyl may be present in unexpected products. Keep naloxone accessible, avoid using alone, and call 911 for unresponsiveness or breathing problems. Supporters should know where naloxone is and how to respond. Harm reduction steps protect life and do not mean the person or treatment team has abandoned a longer-term recovery goal; naloxone should be replaced after use or expiration, and household members can review response steps before a crisis.
Review the plan after every use and every near miss
Ask what happened before, during, and after the event without turning the review into punishment. Update access, treatment intensity, medication, housing, mental health care, transportation, and supportive contacts as needed. Keep lessons from the event while removing steps that were unrealistic. A prevention plan is a working clinical tool, not a contract used to prove blame when recovery becomes difficult; a near miss may reveal a gap in timing, access, communication, or coping before substance use actually occurs.
