This guide looks at sertraline from both a mental health and addiction perspective. It explains how the medication works, whether it can be addictive, how it interacts with alcohol and other substances, what withdrawal symptoms can feel like, and when additional support may be helpful.
We’ll cover:
What Is Sertraline?
You may know the medication as Sertraline, but in the UK it’s sold under the brand name Lustral. The prescription antidepressant is commonly used to treat depression and anxiety-related conditions, and it’s often prescribed when things like low mood, worry or intrusive thoughts start to interfere with everyday life.
It belongs to a group of medicines called SSRIs. In simple terms, these medications affect serotonin, a chemical in the brain that plays a role in mood, sleep and emotional balance. Rather than changing how you think or feel overnight, sertraline is designed to take the edge off symptoms, making them easier to live with and respond to.

What Is Sertraline Used For?
In the UK, sertraline is prescribed for depression and a range of anxiety-related conditions, including generalised anxiety disorder, panic disorder, OCD, PTSD and social anxiety disorder. It’s often offered early on because it’s generally well tolerated and fits easily alongside other treatments.
Many people take sertraline for months or even years, but some people reach a point where they want to revisit whether it’s still the right fit. This can happen when feeling better after some time on sertraline, or they feel the medication isn’t serving them in the way they’d hoped it would.
What are the side effects of sertraline?
Side effects tend to show up most when you first start taking sertraline or when your dose changes. Many settle down after 4-6 weeks, though some can stick around longer than you might expect.
Common side effects include:
- Weight changes
- Headaches
- Nausea or vomiting
- Dizziness or drowsiness
- Dry mouth
- Diarrhoea
- Difficulty sleeping
- Sexual side effects like reduced libido or difficulty reaching orgasm
- Weight changes
*It is also important to note that there is a potential for a risk of increased suicidal ideation and self-harm in the first 4 weeks after starting SSRIs, especially in adolescents. Patients should be aware of these risks and access the right support from their GP or healthcare provider before starting to take them. If you are interested in finding out more, please read this journal by the Royal College of Psychiatrists.
**If side effects are bothering you, it’s worth raising them with your GP or prescriber. Sometimes a slower increase, a dose adjustment, or switching to a different medication makes more sense than trying to push through.
What are the long-term side effects of sertraline?
Not everyone experiences long-term side effects, and plenty of people find that sertraline helps them function far better than they did before. That said, if you’ve noticed your emotions feel muted, your motivation has dropped, or your sleep still feels disrupted, and the side effects are getting in the way of your quality of life, it makes sense to ask whether sertraline is still the right fit.
Certain side effects of sertraline may persist and become long-term, like sexual difficulties or a lower libido, whereas other side effects, like weight gain, may develop over time.

Sertraline and alcohol
As people start to reflect on how sertraline fits into their lives, questions about alcohol may come up, too. Because both sertraline and alcohol affect mood, it’s not uncommon for people to reach for a drink to manage difficult feelings, even though drinking on sertraline is not medically advised.
With that in mind, it’s also worth recognising that some people prescribed sertraline already have a complicated relationship with alcohol or other substances. Antidepressants are often prescribed to people dealing with anxiety, low mood or emotional distress, and for those with a history of substance misuse, alcohol can remain a familiar way of coping, even when medication is part of the picture. That can make cutting back or stopping drinking feel particularly difficult, rather than simply a matter of choice.
When drinking becomes a way of coping with side effects
Some people turn to alcohol to manage the side effects of sertraline because it can feel like a quick fix, especially when you’re waiting for the medication to settle. The trouble is that alcohol tends to make those same side effects worse, for example, worsening depression and anxiety. Before long, it can create a cycle that’s hard to step out of without support.
If that sounds familiar, you’re far from alone. It’s a pattern people can fall into without realising, and recognising it is often the first step toward doing something about it.
How to come off sertraline
Coming off sertraline tends to be easier when it’s done gradually and with guidance from the clinician who prescribes it. Reducing too quickly often leads to withdrawal symptoms, while allowing plenty of time between changes gives your body a chance to adapt.
Before starting, it can help to talk through why you want to stop and whether the timing feels right. Things like current stress levels, support around you, and upcoming life changes can all influence how smooth the process feels.
When you begin tapering, smaller dose reductions with longer gaps are often better tolerated. Tracking how you feel over several days rather than hour by hour can also help. The first week after a reduction can feel strange, and it’s easy to overthink every sensation. Looking at patterns in sleep, mood, energy, and anxiety over time gives a clearer picture.
If symptoms return, it might be withdrawal, a return of earlier symptoms, or a mix of both. Your prescriber can help you work out what’s happening and adjust the plan. Changing pace or direction isn’t a setback. It’s part of responding to what your body is telling you.
What are sertraline withdrawal symptoms?
You might hear this described as withdrawal or discontinuation symptoms. It doesn’t mean sertraline is addictive, but it does mean your body can react if the dose is reduced too quickly, which is why tapering is usually advised.
Symptoms vary from person to person and can include feeling dizzy or unsteady, nausea or stomach upset, headaches, changes in sleep or vivid dreams, irritability, anxiety, low mood, or electric shock sensations in arms, legs or head, often described as “brain zaps”.
What are the other side effects of coming off sertraline?
When people talk about side effects of coming off sertraline, they’re usually referring to both physical symptoms and emotional changes. Some notice they feel more emotionally present or sharper. Others feel more sensitive or exposed for a while, as if their nervous system is adjusting to a new baseline.
There’s no single “right” way to feel, and experiences can change as the taper progresses. If you notice a significant drop in mood, rising panic, or thoughts of harming yourself, it’s important to reach out for help. You can speak to your GP, call NHS 111, or attend A&E if needed. Support is there, and you don’t have to sit with that on your own.

What are the benefits of coming off sertraline?
The benefits of coming off sertraline depend on timing, support and personal circumstances. When the moment feels right, and the process is handled carefully, people often describe feeling more like themselves again. That might mean fewer lingering side effects, a wider emotional range, or a clearer sense of what’s driving their mood without medication in the background.
Some also find that daily life feels simpler without needing to consider medication interactions or side effects.
It’s worth saying clearly that the goal isn’t to come off sertraline at any cost. The goal is stability and a life that feels workable and balanced. Staying on medication longer can be the right choice. Neither path is a failure, and neither is better than the other.
When coming off sertraline feels more difficult than you’d hoped
If attempts to stop sertraline or any other prescription medication addiction haven’t gone smoothly, there’s often more involved than withdrawal symptoms alone. Anxiety or low mood can resurface as the dose reduces. Alcohol or other substances can start playing a bigger role. Stress, poor sleep or reliance on other medications can also complicate things.
When several factors overlap, it can be hard to know what’s driving what. This is where specialist support can help bring clarity, particularly when mental health and substance use are intertwined.
Castle Craig has supported people with addiction and related mental health difficulties since 1988. It’s also Scotland’s only private addiction rehabilitation centre with a dedicated prescription drug detox treatment unit. Support options include inpatient detox and residential rehab, as well as outpatient care across the UK.
It may be worth speaking to a specialist team if mixing sertraline with alcohol or other drugs feels hard to control, if medication use has become worrying, or if mental health and addiction are affecting each other.
You can explore Castle Craig’s treatment options, including 12 Step programmes and 28-day rehab programmes, or visit the admissions for residential rehab page if you feel ready to take that step.
Frequently asked questions
-
Can I take sertraline and alcohol?
NHS guidance recommends avoiding alcohol while taking sertraline, as it can interfere with how the medication works. In reality, many people do drink while on it. The risk is that alcohol can worsen low mood and anxiety, disrupt sleep, and lower inhibitions in ways that aren’t always helpful. There is also a risk that the combination of the two can increase drowsiness, which can impact you if you are involved in caring for a child, for example, or if you are operating high-risk equipment.
If alcohol has become a way of coping with withdrawal symptoms or difficult feelings, that isn’t a personal failing. It’s often a sign that more support would help.
-
Is there such a thing as a sertraline overdose?
Yes. Taking more than your prescribed dose can be dangerous. NHS advice is to contact NHS 111 if you’ve taken more than directed, and to go to A&E if advised. If someone collapses, has a seizure, or you’re seriously concerned, call 999 immediately.
It’s important to be able to recognise the signs of an overdose. These may include extreme agitation, a very fast heartbeat, a high temperature, confusion, muscle stiffness, or seizures. If symptoms appear suddenly or feel severe, seek urgent medical help straight away.
-
Is sertraline used for anxiety?
Yes. Sertraline is commonly prescribed for anxiety-related conditions, including panic disorder, PTSD, OCD and social anxiety disorder, as well as depression.
-
Can sertraline be used to treat my ADHD?
Sertraline isn’t a first-line treatment for ADHD itself. However, ADHD often overlaps with anxiety or depression, and an SSRI may be part of a broader treatment plan. A GP or specialist can help you think through how different treatments might work together.
-
Is sertraline safe during pregnancy?
NHS guidance says sertraline can be used during pregnancy if needed. If you’re pregnant or planning to become pregnant, your doctor will talk through the risks and benefits with you so you can make an informed decision together. Typically, this would involve reducing to the lowest effective dose, and delivery will need to occur in a hospital setting, as the baby will require additional checks after birth.
If circumstances change, try not to stop suddenly. Speak with your prescriber as soon as you can to plan the safest next steps.
