How it works
Sertraline belongs to a group of medicines called Selective Serotonin Re-uptake Inhibitors (SSRIs). Serotonin is one of the chemicals in your brain which helps control your mood. Sertraline and other SSRIs are thought to help by increasing the amount of serotonin in your brain.
Depression is longer lasting and/or more severe than the "low moods" everyone has from time to time due to the stress of everyday life. It is thought to be caused by a chemical imbalance in parts of the brain. This imbalance affects your whole body and can cause emotional and physical symptoms such as feeling low in spirit, loss of interest in activities, being unable to enjoy life, poor appetite or overeating, disturbed sleep, often waking up early, loss of sex drive, lack of energy and feeling guilty over nothing.
PMDD affects some women in the days before their period. PMDD is different from premenstrual syndrome (PMS). The mood symptoms (anger, sadness, tension, etc.) in PMDD are more severe than in PMS and affect the woman's daily activities and relationship with others.
There is no evidence that this medicine is addictive.
Clinical experience has shown that sertraline should not affect the ability to drive or operate machinery. However, make sure you know how sertraline affects you before driving or operating machinery, as it can make some people drowsy or dizzy or affect their concentration.
Use in children
This medicine should not be used in children.
Before you take this medicine
When you must not take it
Do not take this medicine if:
You are taking any of the following medicines:

Do not take sertraline until 14 days after stopping any MAOI, and do not take MAOIs until 14 days after stopping sertraline.
Taking sertraline with MAOIs may cause a serious reaction with signs such as a sudden increase in body temperature, very high blood pressure, rigid muscles, nausea/vomiting and/or fits (convulsions). Your doctor will know when it is safe to start sertraline after the MAOI has been stopped.

How to take it
Swallow the tablets with a glass of water.
When to take it
Take your tablets once a day, either in the morning or in the evening.
Take this medicine at the same time each day. Taking it at the same time each day will have the best effect and will also help you remember when to take it.
It does not matter if you take it before, with or after food.
How long to take it for
Continue taking your medicine for as long as your doctor tells you.
Most antidepressants take time to work, so don't be discouraged if you don't feel better right away. Some of your symptoms may improve in 1 or 2 weeks but it can take up to 4 to 6 weeks to feel any real improvement. Even when you feel well, you will usually have to take sertraline for several months or even longer to make sure the benefits will last.
Make sure you have enough to last over weekends and holidays.
Occasionally the symptoms of depression or other psychiatric conditions may include thoughts of harming yourself or committing suicide. It is possible that these symptoms may continue or increase until the full anti-depressant effect of your medicine becomes apparent (i.e. one to two months).
You or anyone close to you or caring for you should watch for these symptoms and tell your doctor immediately or go to the nearest hospital if you have any distressing thoughts or experiences during this initial period or at any other time.
Also contact your doctor if you experience any worsening of your depression or other symptoms at any time during your treatment.
Do not stop taking this medicine even if you begin to feel better.
Your doctor may decide that you should continue to take it for some time, even when you have overcome your problem. For best effect, this medicine must be taken regularly.
Your doctor will tell you when and how this medicine should be discontinued. Your doctor will usually recommend that you stop treatment by slowly reducing the dosage over a period of several weeks. When you stop treatment with this medicine especially if this is done suddenly, you may experience unwanted side effects such as headache, feeling dizzy, sick, irritable, agitated, lethargic or anxious; sweating; pins and needles or electric shock feelings, changing moods or emotions, or disturbed sleep if sertraline is stopped, particularly if stopped suddenly.
If you forget to take it
Do not take an extra dose. Wait until the next day and take your normal dose then.
Do not take a double dose to make up for missed doses. This may increase the chance of you experiencing side effects.
If you have trouble remembering to take your medicine, ask your pharmacist for some hints to help you remember.
If you take too much (overdose)
If you think that you or anyone else may have taken too much of this medicine, immediately telephone your doctor or the Poisons Information Centre (Tel: 13 11 26 in Australia) for advice. Alternatively go to the Accident and Emergency Department at your nearest hospital.
Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
If you take too much sertraline, you may have some of the following symptoms: sedation, nausea, diarrhoea, vomiting, fast heartbeat, tremor, agitation, dizziness and unconsciousness.
While you are taking this medicine
Things you must do
People taking sertraline may be more likely to think about killing themselves or actually try to do so, especially when sertraline is first started or the dose is changed. Tell your doctor immediately if you have thoughts about killing yourself or if you are close to or care for someone using sertraline who talks about or shows signs of killing him or herself.
All mentions of suicide or violence must be taken seriously.
Occasionally, the symptoms of depression may include thoughts of suicide or self-harm. It is possible that these symptoms continue or get worse during the first one to two months of taking sertraline until the medicine starts to work completely. This is more likely to occur if you are a young adult, i.e. 18 to 24 years of age, and you have not used antidepressant medicines before.
If you or someone you know or care for demonstrates any of the following warning signs of suicide-related behaviour while taking sertraline, contact a doctor immediately, or even go to the nearest hospital for treatment:
- thoughts or talk of death or suicide
- thoughts of talk of self-harm or harm to others
- any recent attempts of suicide or self-harm
- increase in aggressive behaviour, irritability or agitation
- worsening of depression.
Tell your doctor immediately if you become pregnant.
If you are a woman of child-bearing age, you should avoid becoming pregnant while taking sertraline.
Make sure your midwife and/or doctor know you are taking sertraline. When taken during pregnancy, particularly in the last 3 months of pregnancy, medicines like sertraline may increase the risk of a serious condition in babies, called persistent pulmonary hypertension of the newborn (PPHN), making the baby breathe faster and appear bluish. These symptoms usually begin during the first 24 hours after the baby is born. If this happens to your baby you should contact your midwife and/or doctor immediately.
Some people (especially older people or those taking diuretics/water tablets) may experience a lack of sodium in the blood when taking this medicine. Tell your doctor if you get a headache or start to feel dizzy, confused, forgetful, weak, unsteady or unable to concentrate.
Tell your doctor that you are taking this medicine if:
- you are about to be started on any new medicine
- you are breast-feeding or are planning to breast-feed
- you are about to have any blood tests
- you are going to have surgery or an anaesthetic or are going into hospital.
Your doctor may occasionally do tests to make sure the medicine is working and to prevent side effects. Go to your doctor regularly for a check-up.
Tell any other doctors, dentists and pharmacists who are treating you that you take this medicine.
Tell your doctor if, for any reason, you have not taken your medicine exactly as prescribed. Otherwise, your doctor may think that it was not effective and change your treatment unnecessarily.
Tell your doctor if you feel the tablets are not helping your condition.
If you are being treated for depression, be sure to discuss with your doctor any problems you may have and how you feel, especially any feelings of severe sadness, thoughts of suicide, bursts of unusual energy, anger or aggression, or if you become particularly agitated or restless.
Tell your doctor immediately if you have any suicidal thoughts or other mental/mood changes.
Make sure you have enough tablets to last over weekends and holidays.
Things you must not do
- Give this medicine to anyone else, even if their symptoms seem similar to yours
- Take your medicine to treat any other condition unless your doctor or pharmacist tells you to
- Stop taking your medicine, or change the dosage, without first checking with your doctor. If you stop taking it suddenly, your condition may worsen or you may have unwanted side effects (see "Things to be careful of").

You should wait at least 14 days after stopping sertraline before starting any medicines known as monoamine oxidase inhibitors (MAOIs), such as selegiline, phenelzine, tranylcypromine, moclobemide and linezolid.
The effects of sertraline may last for some days after you have stopped taking it.
When your doctor decides that you should stop taking this medicine, the dose may be reduced slowly or the time between the doses increased over 1 to 2 weeks.
