Opioid medication provides relief for moderate to severe pain. However, if the opioid is taken through non-prescribed sources such as heroin, long-term and regular use can lead to several changes in the body. In this guide, we will explore the signs and symptoms of opioid dependence and how professional medical guidance can help.
What is an Opioid Dependence?
There are three main phrases that people often get confused with when it comes to opioid use:
- Physical dependence is when the body naturally adapts to the continuous presence of an opioid. If regular dosage suddenly stops, it causes the body to react and experience withdrawal symptoms.
- Tolerance is when the body becomes accustomed to a specific dose, meaning that a higher dose may be required to achieve the same level of pain relief. Tolerance doesn’t mean that someone is addicted to the drug, but changes in doses should always be managed carefully.
- Opioid addiction is characterised by compulsion to misuse substances. It is typically viewed as behavioural, while tolerance and dependence are physical. Someone who is addicted might feel a loss of control and will continue to misuse despite the clear negative impacts.
What makes opioids so challenging is that they do come in legitimate prescription forms as well as illicit substances. However, even when prescribed, these medications carry a risk of dependence and tolerance, which is why regular medication reviews are needed.
Physical Signs of Opioid Dependence
Physical dependence often becomes noticeable when a scheduled dose is missed, reduced or delayed. This is because the body reacts to a drop in opioid levels in the bloodstream. Common signs include:
- Feeling unwell, restless or uncomfortable
- Finding that a prescribed dose no longer manages pain
Common side effects of opioid use include drowsiness, constipation, dry mouth and small pupils and shouldn’t be seen as evidence of addiction or dependence.
Common Opioid Withdrawal Symptoms and Opioid Addiction Signs
When opioid levels fall in a person who is physically dependent, the body responds in several ways. These can range from mild to severe and also vary from person to person. Typical symptoms of opioid withdrawal include:
- Frequent yawning, watery eyes, runny nose, sweating, chills, goosebumps and restlessness
- Sleep disturbances such as difficulty falling asleep or staying asleep, vivid dreams and severe fatigue
- Muscle aches, joint pain, abdominal cramping, nausea, vomiting and diarrhoea
- Heightened anxiety, irritability, agitation and intense physical or psychological cravings
The onset and duration of these symptoms depend on the specific opioid used, the dosage and individual factors. And because withdrawal is an individual process and everyone will experience different symptoms, it’s important that at-home detoxes are not attempted. Fixed timelines for withdrawal are also inaccurate, as everyone withdraws at different times.
Behavioural and Emotional Signs that Need Assessment
As well as the physical signs listed above, opioid dependence can also manifest in behavioural and emotional shifts – and these often require expert support. Some signs that may require a professional assessment include:
- Experiencing strong cravings, taking larger amounts than originally intended, or making repeated attempts to cut down or stop use
- Maintaining opioid use even though it clearly causes negative side effects regarding health, wellbeing, relationships, employment or finances
- Using medication for reasons other than their intended use, such as to manage stress, sleep and emotions or seeking additional supplies outside of standard prescription agreements
Context is vital when looking at these signs, however. Requesting a repeat prescription or experiencing distress due to chronic pain and needing opioid medication shouldn’t be confused with addiction. But this is where a medical assessment can come in handy.
Opioid Overdose Warning Signs
Opioid overdose is completely different from physical dependence or withdrawal. An overdose is an immediate and life-threatening medical emergency and occurs when an excessive amount of opioid depresses the central nervous system, impairing the body’s ability to breathe. Signs to watch out for include:
- Slow, shallow, irregular or completely absent breathing
- Unresponsiveness or inability to be awakened
- Unusual snoring, deep gurgling sounds or choking noises
- Pale, cold or clammy skin with discolouration around the lips, tongue or fingernails
If you suspect an overdose, call 999 immediately and follow the operator’s guidance. You shouldn’t leave anyone who you suspect to be in overdose.
When and How to Seek Help
You should never stop taking prescribed opioids suddenly without permission from a GP or prescriber. If you or someone you care about is having trouble managing prescribed opioids, it’s important to consider professional help. Attempting to stop using opioids without medical supervision could trigger dangerous withdrawal symptoms.
If you’re using non-prescribed opioids or feel like you have lost control over the dosage of prescription medication, you can access local NHS drug and alcohol services. Alternatively, if you’re experiencing severe withdrawal symptoms, don’t hesitate to call 999.
There’s also the option of residential rehab. Here, individuals have access to a structured and evidence-based approach to treatment tailored to individual needs and away from triggers. It starts with an assessment covering physical health, pain management requirements, mental health and personal circumstances and will then lead to a safe detox and various complementary therapies. In doing so, both the physical and psychological aspects of addictions are catered to.
Detox alone doesn’t guarantee sobriety. Instead, a multifaceted approach is required, focusing on life skills support, relapse prevention strategies, ongoing aftercare and peer support groups.
What’s the Best Treatment for Me?
Appropriate treatment will depend on several personal factors. For a person who is physically dependent and wants to stop, they can undergo a medically supervised gradual taper that is monitored by a GP.
But for those diagnosed with a severe opioid use disorder, residential rehab treatment may be required alongside substitute prescribing. This is known as medication-assisted treatment and helps to stabilise brain chemistry, eliminate severe withdrawal symptoms and suppress cravings.
