Sertraline is a drug used to treat certain types of mental health disorders, such as depression, anxiety, obsessive compulsive disorder (OCD), and post traumatic stress disorder (PTSD). It is an SSRI, or selective serotonin reuptake inhibitor. It works by altering the way the brain processes a chemical called serotonin. These drugs are more commonly referred to as antidepressants. The branded version of Sertraline made by Pfizer is called Lustral.
About one in four adults in the UK is thought to be affected by a mental health problem. There are several different types of mental health disorder, and these can cause a variety of different symptoms.
What conditions does Sertraline treat?
Obsessive compulsive disorder (OCD) for example, is an anxiety disorder which is characterised by having regular, unwanted or unpleasant thoughts (obsessions) or urges to perform certain actions (compulsions). It’s a condition many might not feel comfortable seeking help for, so it’s fairly common for OCD to go undiagnosed for some time; it might only be when these obsessions or compulsions begin to interfere with normal daily life that someone seeks help.
Depression is a condition where someone feels down or fed up on a regular or continual basis for a prolonged period. Bouts of depression may go on for several weeks or months. In some cases it may be triggered by a specific event, such as losing a loved one or losing a job. But it can run in families too, and occur for no reason in particular.
Post traumatic stress disorder, or PTSD, comes about as a result of experiencing a particularly stressful or frightening situation (such as violence or a serious life-threatening illness). It’s thought to affect about a third of people who go through a traumatic event, and can cause flashbacks and bad dreams (in which someone relives the experience).
Each mental health condition is different, and as such, there are various therapies and techniques available to help people overcome them and keep them under control. For example, cognitive behavioural therapy, or CBT, is a method used to help treat several types of anxiety disorder, including OCD and PTSD. Counselling is another talking therapy route, and a doctor may recommend attending self-help groups in certain cases.
Antidepressant medication is a further form of treatment for mental health disorders such as OCD, PTSD and depression. When it is prescribed in addition to a talking therapy, this is referred to as combination treatment.

How does Sertraline work?
Sertraline and other SSRIs work by altering the way the brain processes a chemical called serotonin. Serotonin plays an important role in the transmission of signals in the brain. It’s released and reabsorbed by nerve cells, and when serotonin levels are lower than usual, this causes problems with transmitting signals between nerve cells and is thought to contribute towards depression. SSRIs, or selective serotonin reuptake inhibitors, work by preventing this chemical from being reabsorbed by nerve cells, so there’s more available to transmit signals as needed. This eases symptoms of depression or anxiety.

Do not use Sertraline if: you are allergic to anything in it; you have a liver problem; you are taking a type of medicine called an MAOI or have in the past two weeks; are taking pimozide.
Your prescriber needs to know if you: are pregnant or breastfeeding; have had bipolar disorder or schizophrenia; have had suicidal thoughts or thoughts relating to self-harm before; have serotonin syndrome; have low blood sodium levels; have kidney or liver problems; are diabetic; have ever had a fit; are having electroconvulsive therapy; intend to consume alcohol when taking this treatment; or have had a bleeding disorder before.
Taking it with other medications
It is important to tell your prescriber about any other medicines you are using.
Do not use Sertraline if you are also taking: MAOIs such as moclobemide or selegiline; or linezolid.
The following medicines may interact with Sertraline, so you should tell your doctor if you are taking them: St John’s Wort; medicine for chronic pain or amnesia, such as fentanyl; sedatives like diazepam; water tablets; phenytoin or other anti epilepsy medicines; diabetes medicines such as tolbutamide; treatments for stomach acid and ulcers such as cimetidine; medications for mental health conditions such as lithium, amitriptyline, nortriptyline, perphenazine, levomepromazine and olanzapine; drugs to help with an irregular heartbeat, such as flecainide or propafenone; tryptophan or sumatriptan; fenfluramine; warfarin; aspirin; painkillers known as NSAIDs; or tramadol.
Pregnancy and breastfeeding
If you are trying to conceive, are pregnant or become pregnant, or are breastfeeding, do not take Sertraline tablets and speak to your doctor as soon as possible.
Driving and using machines
Sertraline can cause side effects like drowsiness which can affect your ability to drive. If you experience any side effects like this, do not drive or use any heavy machines and let your doctor know. You could change the time of day that you take it if you experience tiredness; some people prefer to take it at night for this reason.
Food, drink and alcohol
You should not drink alcohol or grapefruit juice when using Sertraline. Alcohol can lessen the feelings of sadness or anxiety for an hour or two but in the long term it makes these feelings much worse, so it’s much better to avoid it altogether whilst you’re taking Sertraline.
