A sudden change during dual diagnosis treatment needs a fresh assessment of what is happening now. New confusion, a marked change in sleep or mood, unusual perceptions, worsening physical symptoms, or a return to substance use should not be explained away solely because the person is already in treatment.
Some changes require emergency care; others need prompt contact with the treating clinician and a review of the plan. The purpose is to identify the right response, not to make a diagnosis from a list of symptoms. This guide explains how a person, supporter, or care team can communicate a change clearly and keep responsibility from becoming confused.
Recognize when routine contact is not enough
Call local emergency services for a suspected overdose, serious breathing difficulty, a seizure, collapse, severe confusion, or another immediate medical emergency. Suicidal intent, imminent danger, or inability to remain safe also requires urgent help. Do not wait for a routine therapy appointment or an admissions team to reply.
If an opioid overdose may be involved and naloxone is available, use it according to the product instructions and emergency guidance while obtaining emergency assistance. A person who is difficult to wake or breathing abnormally should not simply be left to sleep.
Tell emergency professionals about known substances, prescribed medication, recent changes, and relevant health conditions. If something is uncertain, say that rather than guessing. The immediate priority is appropriate assessment and care, not determining who is responsible for the change.
For concerning changes that are not an obvious emergency, contact the treating service promptly. Ask which clinician should assess the problem and how soon. A message marked urgent is not the same as a confirmed clinical response.
Describe the change in observable terms
Start with what is different from the person’s usual or recent state. For example, describe how much sleep has changed, whether the person can follow a conversation, what they have said about safety, or whether they can eat, drink, and manage ordinary tasks.
Include the time the change began and whether it is getting better, worse, or fluctuating. Explain any known change in alcohol, drug use, prescribed medication, missed doses, physical illness, or treatment setting. These details help the clinician decide what needs assessment.
Avoid relying only on labels such as relapse, panic, manipulation, or noncompliance. They can obscure the actual event and may imply a cause that has not been established. A factual description leaves more room to consider the full clinical picture.
If several people have observed different things, identify who saw what and when. Conflicting accounts can be relevant information; they do not need to be resolved by the family before the team is contacted.
Keep more than one explanation open
Psychiatric symptoms, substance effects, withdrawal, medication effects, sleep disruption, and physical illness can overlap. A new symptom may require a different assessment from the one completed at admission. The fact that someone has a known diagnosis does not establish the cause of every later change.

Ask the clinician what needs to be checked now, which explanations remain possible, and whether the current setting can carry out the required assessment. The plan can respond to risk while the diagnosis remains provisional.
The guide to co-occurring and substance-induced symptoms explains why the timeline matters. It should not be used to postpone care while waiting to see whether a concerning symptom disappears.
Report major changes in sleep, energy, and behavior
A substantial reduction in sleep accompanied by unusually high energy, increased activity, impulsive behavior, or marked irritability deserves clinical attention. These observations do not diagnose bipolar disorder, but they may change the assessment and treatment priorities.

Tell the team what the person is actually experiencing rather than assuming the change is a positive burst of recovery motivation or simply unwillingness to follow the schedule. Likewise, severe low mood, hopelessness, or statements about self-harm should be communicated directly.
Ask whether planned therapy or activities should change while the symptoms are assessed. The decision should be made with the appropriate clinicians, not by expecting the person to continue an unchanged timetable regardless of their condition.
Review medication changes without changing treatment yourself
Prepare the current medication list, including new prescriptions, stopped medicines, recent changes, as-needed use, supplements, and nonprescribed substances. If more than one clinician prescribes, identify each one. Note any uncertainty about what has actually been taken.

Ask a qualified clinician whether a medicine could be relevant and what to do next. Do not abruptly stop, restart, or alter prescribed medication based on a guess about the symptom. The appropriate response can depend on the medicine, the reason it is prescribed, and the current clinical situation.
If the usual prescriber is unavailable, ask which service can provide timely advice. A therapist, coach, or family member should not be left to make prescribing decisions outside their role.
Reassess substance use and withdrawal risks honestly
If alcohol or drug use has resumed, tell the clinical team what is known about the substance, timing, amount, and any other use. The purpose is to support an appropriate assessment. Fear of disappointing staff or losing a place can make disclosure harder, so ask how the service handles this situation.
For possible alcohol or sedative dependence, get medical advice before abrupt stopping or substantial changes. A program’s expectation of abstinence does not remove the need for safe withdrawal planning. The team must consider the actual pattern and current symptoms.

A return to use should trigger a clinical response that considers immediate safety and the treatment plan. It should not be treated only as a breach of a residential rule or a reason to postpone psychiatric care.
Identify who is responsible for the next action
Ask for a named clinician or service to take responsibility for the reassessment. If the person is in residential care, clarify who is available on site, who is on call, and whether a hospital or other specialist service is needed.
In outpatient care, establish whether the current team can assess the change promptly. If it cannot, ask for a clear route to another appropriate service. A recommendation to seek help should specify the type of help and how urgent the situation is.
If a transfer is needed, the sending and receiving teams should exchange relevant information with appropriate authorization. Ask who remains responsible while arrangements are made. Avoid a gap in which one service assumes the person has left and the other has not yet accepted care.
Support the person without turning observation into surveillance
A supporter can help describe changes, arrange transport, gather medication information, or accompany the person when appropriate. Ask what help is useful and what information may be shared. The person’s preferences matter alongside the clinicians’ safety responsibilities.
If there is immediate danger, prioritize emergency assistance. For ongoing concerns, discuss a manageable communication plan rather than making a relative responsible for constant monitoring. Family members may also need guidance and support for their own distress.
Where threats or violence are present, seek appropriate emergency or specialist help. Do not arrange a confrontational family meeting as a substitute for a safety assessment.
Check that the advice is understood
After speaking with a clinician, repeat the agreed next step in your own words. Clarify where the assessment will happen, who should attend, and what to do if symptoms worsen before then. If the instructions are unclear or conflict with advice from another service, ask the professionals to resolve the difference.
Keep a brief record of the contact and plan when practical. This can help if care passes between shifts or services. Documentation should support action; it should never delay urgent assistance while someone tries to produce a complete account.
Update the care plan after the immediate concern is addressed
Once the situation is assessed, ask what has changed in the working formulation, medication plan, level of care, and follow-up. Record which questions remain open and when they will be reviewed. A resolved immediate crisis may still reveal a gap in routine treatment.
Use the care plan review guide to connect the new findings with longer-term goals. Clarify warning signs, routine contacts, urgent routes, and what should happen if the same pattern returns.
Reassessment is part of responsive treatment. The useful outcome is an updated plan that reflects the person’s current needs and makes the next action, responsible professional, and appropriate level of support clear.
