Get Help For Prescription Drug Addiction
Millions of people are prescribed drugs each year to help with pain, sleep problems, anxiety, and depression. For most, they’re a short-term solution.
For some, what starts as a prescription can become a dependency. It’s a pattern we’ve long seen happening in the US, but it’s increasingly common across the UK and Europe, too.
A major Irish study tracking prescription drug misuse between 2010 and 2020 found that benzodiazepines and Z-drugs caused the most harm across every measure. This accounted for the largest share of people entering treatment, intentional overdoses, and drug-related deaths.
If you’re worried that you might be struggling with prescription drug addiction because you have started to notice some signs, then the team at Smarmore Castle are here to help.
Our treatment, supported by over 40 years of experience, has been developed to help treat each individual holistically. That means that we are here to help with the physical, psychological, and emotional aspects that cause you to rely on prescription drugs. Below, we look at how dependency develops and the signs worth knowing about.
What is Prescription Drug Addiction?
Prescription drug addiction can develop when someone becomes physically or psychologically dependent on a medication prescribed for a legitimate medical reason. It can also occur when medication is accessed outside a prescription (though this is less common).
Prescription drug dependence can develop even when medication is taken exactly as directed.
Dependency does not mean weakness or failure. The drugs most often involved in prescription addiction, including opioids, benzodiazepines, and gabapentinoids, are powerful substances. They act directly on the brain’s reward and regulation systems. The body adapts to them, and over time, it begins to rely on them to feel or function normally.
Dependency that begins with a legitimate prescription follows a different path entirely from deliberate misuse. For many people, the line between therapeutic use and dependency shifts gradually, without a clear moment of decision.
Understanding the signs and acknowledging the problem is the first step towards recovery. At Smarmore Castle, we recognise the complexity of prescription drug addiction and offer comprehensive, tailored treatment plans to address it.

How prescription drug addiction develops
Tolerance is usually the first sign. The same dose no longer has the same effect. You start taking your medication earlier than planned. The brain is adapting, not failing you.
As tolerance increases, some people take higher doses to reach the same relief. Others find that stopping, even briefly, brings on withdrawal symptoms they weren’t expecting. These symptoms include anxiety and disrupted sleep. The brain has reorganised itself around the presence of the drug in the body.
According to research published in Drug and Alcohol Dependence and summarised by the Health Research Board, benzodiazepines consistently account for the greatest proportion of treatment demand. They also account for the number of overdoses and drug-related deaths linked to prescription drug misuse in Ireland.
The transition from prescribed use to dependency can take weeks or months. It often goes unrecognised, both by the person experiencing it and by those around them.
Types of prescription drugs linked to addiction
Opioid addiction and prescription drugs
Opioids include medications such as codeine, tramadol, oxycodone, and fentanyl. They are prescribed for moderate to severe pain. They are among the most effective pain-relief medications available. They are also among the most addictive.
Opioids attach to pain-control pathways in the brain, triggering a sense of relief and, over time, reward. With regular use, the brain starts producing fewer of its own natural painkillers. It comes to rely on the medication instead. Withdrawal should always be managed with medical support.
Benzodiazepine addiction
Benzodiazepines include diazepam, alprazolam, and temazepam. They are prescribed for anxiety, panic disorder, and insomnia. They work by boosting a calming chemical in the brain called GABA.
Benzodiazepine addiction can develop faster than most people expect. The HSE advises that benzodiazepines are generally not recommended beyond two to four weeks. This is because tolerance develops quickly. Many people in Ireland have been prescribed them for years, with no supported plan for stopping.
Stopping benzodiazepines without medical guidance is not recommended. A gradual, supervised reduction is the standard approach.
Gabapentinoids (pregabalin and gabapentin)
Pregabalin and gabapentin are prescribed for nerve pain, epilepsy, and increasingly for anxiety. Their potential for dependency has become a recognised concern in Ireland and across Europe. Prescribing rates have been rising sharply over the past decade.
Research published in Drug and Alcohol Dependence and summarised by the Health Research Board found that gabapentinoids, particularly pregabalin, represent the most rapidly escalating threat among prescription drugs misused in Ireland. According to this report, treatment demand is growing 44% annually, and drug-related deaths are rising 35% each year.
Many people who become dependent on pregabalin weren’t warned that this was a risk when their prescription was issued. If you have been prescribed pregabalin and are concerned about your use, you can find more detailed information on our pregabalin addiction page.
Stimulants
Stimulants such as methylphenidate and amphetamine salts are prescribed for Attention Deficit Hyperactivity Disorder (ADHD) and, less commonly, for narcolepsy. When taken as prescribed, they help regulate attention and impulse control.
Stimulants can also be misused, taken at higher doses than prescribed or by people without an ADHD diagnosis. Dependency on stimulants tends to present differently from opioid or benzodiazepine dependency, often involving psychological reliance and withdrawal effects, including fatigue, low mood, and difficulty concentrating. These effects can last several weeks, which is why support during this period matters.
Signs and symptoms of prescription drug addiction
These signs aren’t a clinical diagnosis, and you don’t need to recognise all of them. If several feel familiar, that’s enough of a reason to speak to someone.
Behavioural signs
Some people start using a medication prescribed for one condition to manage something else entirely, such as a painkiller taken for anxiety, or a sleep aid used to get through a stressful day.
A gradual withdrawal from the things that used to matter, relationships, work, and routines, can be a warning sign. It may indicate that medication use has started to take hold. These shifts are often more obvious to others than to the person living them.
Physical symptoms
Physical signs vary by drug. With opioids, heightened sensitivity to pain when not taking the medication is common. With benzodiazepines, tremors and disrupted sleep are often the first signs.
You may notice that stopping or reducing your dose causes physical symptoms you weren’t expecting. Your body has adapted to the drug’s presence. Those symptoms are the adjustment, not a measure of how far you have to go.
Psychological symptoms
Persistent anxiety is among the most common psychological effects of dependency on benzodiazepines and opioids. It often appears before people recognise what’s causing it.
Some people experience strong cravings, intrusive thoughts about their medication, or a sense that they can’t cope without it.
Feelings of shame about whether your experience ‘counts’ as addiction are common when a prescription was involved. The treatment is the same regardless of how it started.
Risks of prescription drug misuse
Taking opioids or benzodiazepines at higher doses than prescribed increases the risk of overdose, because both suppress the central nervous system.
Mixing prescription medications, or combining them with alcohol, significantly increases these risks. The HSE advises that opioids and benzodiazepines should never be taken together without explicit medical oversight, as the combination can suppress breathing to a dangerous degree.
Long-term use of some prescription drugs affects how the brain processes information and regulates mood. The specifics depend on the drug, but the effects are real and worth discussing with a clinician.
Prescription drug withdrawal
Withdrawal from benzodiazepines and opioids can be medically serious. For other prescription drugs, it’s uncomfortable but manageable with the right support.
Benzodiazepine withdrawal in particular can cause seizures in some cases, especially after prolonged or high-dose use. Stopping benzodiazepines without medical guidance is not recommended. A gradual, supervised reduction is the standard approach.
Opioid withdrawal isn’t usually life-threatening, but the physical experience is severe. Muscle pain, nausea, and intense anxiety are common in the first 72 hours. Medication-assisted treatment, including the use of buprenorphine, can reduce the severity of opioid withdrawal.
At Smarmore Castle, our medically supervised detox programme is designed around your specific medication history, the dose you have been taking, and the pace at which your body can safely adjust. Our clinical team manages the pace of reduction based on your medication history and how your body responds.
Why this is a growing concern in Ireland
Prescription drug dependency is not a niche issue in Ireland. Research published in Drug and Alcohol Dependence and summarised by the Health Research Board confirms that benzodiazepines and prescription opioids consistently feature among the most reported substances in Irish addiction treatment data. Tramadol and codeine are also the most commonly cited opioids in overdoses and deaths.
Ireland has one of the highest rates of benzodiazepine prescribing in Europe. A significant proportion of these prescriptions are issued for longer than the clinically recommended period. This has left many people without a clear or supported pathway to come off their medication.
According to the same Health Research Board analysis, pregabalin-related harms increased sharply between 2010 and 2020. This happened at the same time as rising prescribing trends and growing misuse in combination with opioids and benzodiazepines.
Prescription dependency often develops gradually, through circumstances that were difficult to see clearly at the time. If you want to understand what’s happened and what comes next, our team is here to work through that with you.
Can you recover from prescription drug addiction?
Yes. Prescription drug addiction is a treatable condition, and recovery is a realistic outcome with the right support.
Recovery looks different for everyone. Some people move through treatment and feel steady. Others find certain life events stir things up in ways they didn’t expect. That’s not a sign that something has gone wrong.
The plan we build with you starts from where you are, not where treatment guidelines assume you should be.
It’s to understand what the medication was managing, address that underlying need through evidence-based therapy, and build a sustainable life beyond dependency. Our support doesn’t stop at discharge. Aftercare and alumni connections are part of how lasting recovery is built.
Treatment for prescription drug addiction
Prescription drug addiction treatment at Smarmore Castle begins with a thorough assessment of your physical health. It also considers your medication history and the psychological factors that may have contributed to dependency. Assessment comes first. What you need depends entirely on your medication history, your physical health, and what you are carrying psychologically.
Where medical detox is required, it is managed by our clinical team and paced to minimise discomfort and risk. We use evidence-based protocols for withdrawal management, including medication to ease withdrawal where needed.
Alongside detox, we work with you therapeutically. Sessions draw on Cognitive Behavioural Therapy (CBT) and trauma-informed approaches, alongside group work grounded in 12 Step principles. We also offer family therapy for those whose loved ones have been affected by their prescription drug use. We also provide a continuing care programme to support patients after they leave rehab.
Smarmore Castle is a residential facility, which means you have uninterrupted time and space to focus on recovery. This takes you away from the environment and pressures that may have contributed to your dependency.

Frequently Asked Questions About Prescription Drug Addiction
-
Which prescription drugs are most addictive?
Opioids, benzodiazepines, and gabapentinoids such as pregabalin carry the highest risk of dependency among commonly prescribed medications. Stimulants prescribed for ADHD can also lead to dependency, particularly when misused. The risk varies depending on the drug, the dose, and the duration of use.
-
Can I stop taking my medication on my own?
For some medications, stopping abruptly is not safe. Benzodiazepines and some opioids require a gradual, medically supervised reduction to minimise the risk of serious withdrawal effects. If you want to stop taking prescribed medication, please speak to a doctor or contact our team before making any changes. This isn’t a decision that should be made without clinical guidance.
