Inpatient treatment, sometimes called residential rehab, means residing full-time at a treatment centre. You’re away from daily pressures and familiar environments, with round-the-clock medical and therapeutic support around you.

Most people consider their options carefully, often after months of weighing up whether to begin treatment. If that’s where you are, just deciding to enter treatment is already a major step. 

Castle Health provides inpatient treatment for alcohol dependency, drug dependency, and addictive behaviours such as gambling. We have two residential centres: Castle Craig in Scotland and Smarmore Castle in Ireland. Treatment is shaped around you, your history, and what you need to get well.

If you’re ready to talk through your options, our admissions team offers a private addiction assessment that is confidential and free of pressure.

Inpatient treatment explained: What residential rehab involves

Inpatient treatment differs from outpatient treatment, in which you attend sessions and return home each day. In a residential setting, the medical support, therapy, daily routine, and sense of community all work together.

Where a detox is needed, it takes place first. Inpatient alcohol detox at Castle Craig typically involves medication to manage withdrawal, with the dose reduced gradually under nursing supervision. For opioids, stimulants and benzodiazepines, there’s a different medication protocol. Your admissions team can explain what to expect for your specific situation.

Once detox is complete, the therapeutic programme begins, including individual sessions, group work, 12 Step facilitation, and time built in to rest. 

The length of your stay depends on your individual needs. Most people start with a six-week Foundation Programme. Those with more complex needs or a longer history of dependency can move on to an Advanced Programme.

Our admissions team can talk through medically supported detox and programme options with you when you first get in touch.

Who is inpatient treatment for?

There’s no single profile of someone who comes to us for inpatient care. Inpatient treatment tends to be particularly useful when:

  • Outpatient or online support has not been enough
  • The home environment makes recovery difficult
  • Physical withdrawal needs medical supervision
  • Someone is managing both addiction and mental health needs at the same time

A review in Advances in Psychiatric Treatment found that inpatient care is the right option for people with more complex needs, including those at risk of severe withdrawal.

If you’re unsure whether inpatient treatment is right for you, call us. Our team will explain your options and answer whatever questions you have. 

Inpatient alcohol treatment, drug treatment, and behavioural addictions

Castle Health provides inpatient treatment for substance dependencies and some behavioural addictions, including gambling. Treatment is available at Castle Craig and Smarmore Castle, and is tailored to the specific substance or behaviour involved.

Each person’s dependence is different, and so is each treatment plan. If you’re looking for support with a specific addiction, our addiction treatment pages cover the conditions we treat in more detail, including the therapies and approaches most relevant to each.

Inpatient mental health treatment alongside addiction care

Many people who come to us are managing both addiction and a mental health condition at the same time. Depression, anxiety, PTSD, and trauma are common with dependency, and treating one without the other rarely produces lasting results.

Research on co-occurring disorders shows that addiction and mental health conditions share common brain pathways, which is part of why they appear together so often. 

One national study found that around 19% of people in addiction treatment had significant mental health needs, with a further 25% reporting current mental health symptoms. 

At Castle Craig, consultant psychiatrists are available throughout treatment. If you arrive with a psychiatric diagnosis or develop mental health needs during treatment, the team treats both as part of the same plan.

What about inpatient eating disorder treatment?

Eating disorders are complex and can require specialist medical treatment, particularly when physical health is at risk. Inpatient care in a specialist eating disorder setting may be needed for medical monitoring.

A study published in the Journal of Affective Disorders found that residential treatment works better than day programmes for people with more severe eating disorders.

Castle Health can support people who are living with an eating disorder alongside addiction. Where specialist eating disorder treatment is indicated, we’ll help you find the right care within or outside our network.

“I contacted Castle Health [formerly CATCH] with a view to getting online support after a period in rehab. They recommended recovery coaching and arranged for me to meet my coach in person as the first of 10 meetings. I continued the coaching on Zoom as I live in France. I was very happy with my 10 sessions and feel I am in a good place to continue my recovery.”<br />

What to expect from inpatient treatment with Castle Health

Your first call and private addiction assessment

The first step is a confidential conversation with our admissions team. They’ll ask about your history, your health, and what has brought you to this point. There’s no pressure and no obligation. The purpose of a private addiction assessment is to understand your situation and talk through what might help.

Admissions and preparing for residential rehab

Once inpatient treatment is the agreed plan, the admissions team takes you through what to expect on arrival, what to bring, and how to prepare those close to you. You can read more about the rehab admissions process.

On arrival at Castle Craig, you’re met by nursing and admissions staff and taken to Kirkurd House, the dedicated admissions unit. A medical assessment takes place as soon as possible, and if a detox is needed, it begins straight away. You stay in the admissions unit until you’re assessed as medically ready to join the main community.

Detox, therapy, and daily routine

The clinical team monitors withdrawal carefully, and medication is adjusted based on how you respond. Detox can affect your mood, concentration, and energy levels, and the team will support you throughout.

Once detox is complete, the Foundation Programme begins. A typical day at Castle Craig includes individual therapy, group therapy, educational workshops, and 12 Step facilitation sessions. Evenings and weekends are left for rest and time with other patients. The routine is consistent, and that predictability is a welcome change when you’re early in recovery.

Recovery from addiction is not straightforward, and some days will be harder than others. Therapy helps you develop the skills and insights to manage the hard days, both during treatment and after you leave.

Continuing care after inpatient treatment

Research consistently shows that longer engagement with treatment leads to better outcomes. From the first weeks of your stay, your focal therapist begins working with you on a plan for continuing care after inpatient treatment

Castle Health’s continuing care is delivered online, and local outpatient clinics are available in parts of the UK and the Netherlands. Our team can also help you connect with AA or NA groups near you, so that community support is in place before you leave.

 

If someone in your life may need inpatient treatment

When someone in your life is living with an addiction, it can be hard to know what to do. You might question whether it’s serious enough for residential treatment, particularly if the person is minimising the problem.

You don’t need to have worked everything out before calling us. Our admissions team can talk through what you’re seeing, explain what inpatient treatment involves, and help you understand the options.

Supporting someone before treatment

If you want to talk to them about it, keep it calm and don’t push for an immediate decision. Focus on what you’ve noticed and how it’s affected you. Encourage them to explore an assessment rather than committing to treatment outright. 

Family support during and after treatment

Addiction affects everyone close to the person in treatment. At Castle Craig, we offer a dedicated family programme that runs alongside the patient programme. Family members can attend workshops on addiction and take part in family therapy sessions to rebuild communication and trust.

 

Going home is a big moment for families too. Our continuing care planning includes guidance on what that looks like in practice.

Frequently asked questions about inpatient treatment

How long does inpatient treatment usually last?

The length of your stay depends on your history, any mental health needs, and how treatment progresses. At Castle Craig, the Foundation Programme runs for six weeks. An Advanced Programme is available for those who benefit from more time, particularly people with a long history of dependency or complex underlying needs. Your admissions team can give you a clearer picture.

Can I use my phone during inpatient treatment?

Phone and device access is restricted during residential treatment. This is a deliberate part of the programme, as time away from screens and the usual noise helps. Each centre will explain its own policy before admission, and specific arrangements can be discussed with the admissions team.

Can I have visitors during inpatient treatment?

Visiting arrangements vary between centres and depend on where you are in treatment. Visits are usually planned in collaboration with your therapist, with timing based on what is clinically appropriate at that stage of your recovery. Your admissions team can explain the policy at each centre when you enquire.

Is inpatient treatment private?

Yes. Castle Health’s inpatient treatment is private and confidential. Your admissions team can walk you through exactly what information is collected, who may have access to it, and how your privacy is protected throughout treatment. Consent forms are completed on arrival, and you can update your preferences at any point during your stay.

What should I pack for inpatient treatment?

The admissions team will confirm the full list before you arrive. Generally, you’ll need comfortable, practical clothing, toiletries, and any prescribed medication in its original packaging. There is a clear list of items that are not permitted on site, and the team will go through this with you before admission.
