What this medicine is used for
Sertraline is used to treat:
social anxiety disorder or social phobia
Pre-Menstrual Dysphoric Disorder (PMDD)
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 that 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, loss of sex drive and lack of energy.
PMDD affects some women in the days before their period. It is different from premenstrual syndrome (PMS). The mood symptoms (such as anger, sadness, tension, etc.) in PMDD are more severe than in PMS and affect the woman’s daily activities and relationships with others.
Sertraline belongs to a group of medicines called Selective Serotonin Re-uptake Inhibitors (SSRIs).
Serotonin is one of the chemicals in your brain that helps control your mood. Sertraline and other SSRIs are thought to help by increasing the amount of serotonin in your brain.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed it for another reason.
This medicine is not addictive.
This medicine is available only with a doctor’s prescription.
There is not enough information to recommend the use of this medicine for depression in children under the age of 18 years.

How to take this medicine
Follow all directions given to you by your doctor or pharmacist carefully.
They may differ from the information contained within this leaflet.
If you do not understand the instructions on the label, ask your doctor or pharmacist for help.
How much to take
Your doctor or pharmacist will tell you how much of this medicine you should take. This will depend on your condition and whether you are taking any other medicines.
The usual starting dose is one 50 mg tablet each day. The dose can be increased gradually up to 200 mg a day if necessary.
Social Phobia (Social Anxiety Disorder)
The usual starting dose is 25 mg per day (half a 50 mg tablet), increasing to 50 mg per day after one week.
The maximum recommended dose is 200 mg per day.
Pre-Menstrual Dysphoric Disorder (PMDD)
The usual starting dose is one 50 mg tablet each day, either throughout the menstrual cycle (to a maximum of 150 mg daily) or for the last 14 days before the start of your period (to a maximum of 100 mg daily).
How to take it
Swallow the tablets with a full glass of water.
When to take it
Take your medicine at about the same time each day in the morning.
Taking it at the same time each day will have the best effect. It will also help you remember when to take it.
It does not matter if you take this medicine before 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.
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, 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.
Contact your doctor if you experience any worsening of your depression or other symptoms at any time during your treatment.
If you forget to take it
If it is almost time to take your next dose, skip the dose you missed and take your next dose when you are meant to.
Otherwise, take it as soon as you remember, and then go back to taking your medicine as you would normally.
Do not take a double dose to make up for the dose that you missed.
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)
Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26 in Australia) for advice or go to Accident and Emergency Department at your nearest hospital, if you think that you or anyone else may have taken too much of this medicine. 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 experience sedation, nausea, diarrhoea, vomiting, fast heartbeat, tremor, agitation, dizziness and unconsciousness.
While you are taking this medicine
Things you must do
If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking sertraline.
Tell any other doctors, dentists and pharmacists who are treating you that you take this medicine.
If you become pregnant while taking this medicine, tell your doctor immediately. If you are a woman of child-bearing age, you should avoid becoming pregnant while taking sertraline.
When taken during pregnancy, particularly in the last 3 months of pregnancy, 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.
Tell your doctor immediately if you have any suicidal thoughts or other mental/mood changes.
Depressive symptoms, including thoughts of suicide or self-harm, may worsen during the first one to two months of taking sertraline or after your dose changes. These symptoms should stop when the full effect of sertraline takes place.
This is more likely to occur if you are a young adult under 24 years of age, and you have not used antidepressant medicines before.
If you or someone you know demonstrates any of the following warning signs of suicide-related behaviour while taking sertraline, contact a doctor or mental health professional immediately:
thoughts or talk of death or suicide
thoughts or 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
All mentions of suicide or violence must be taken seriously.
If you are going to have surgery, tell the surgeon or anaesthetist that you are taking this medicine.
It may affect other medicines used during surgery.

Do not take this medicine to treat any other complaints unless your doctor or pharmacist tells you to.
Do not give this medicine to anyone else, even if they have the same condition as you.
Do not stop taking your medicine or lower the dosage without checking with your doctor.
If you stop taking it suddenly, your condition may worsen or you may have unwanted side effects.

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, 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.
Things to be careful of
Be careful driving or operating machinery until you know how this medicine affects you.
This medicine may cause dizziness, drowsiness or impaired concentration in some people. If you have any of these symptoms, do not drive, operate machinery, or do anything else that could be dangerous.

You should wait at least 14 days after stopping sertraline before starting any other medicines for depression or MAOIs.
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.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking sertraline.
