7. Product details

1. Why am I using ZOLOFT?

ZOLOFT contains the active ingredient sertraline hydrochloride. ZOLOFT belongs to a group of medicines called selective serotonin reuptake inhibitors (SSRIs). They are thought to work by blocking the uptake of a chemical called serotonin into nerve cells in the brain. Serotonin and other chemicals called amines are involved in controlling mood.

ZOLOFT is used to treat depression and conditions called obsessive compulsive disorder (OCD), panic disorder, social phobia (social anxiety disorder) and premenstrual dysphoric disorder (PMDD).

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 relationships with others.

ZOLOFT should not be used in children and adolescents under the age of 18 years for the treatment of any medical condition other than obsessive compulsive disorder (OCD). The safety and efficacy of ZOLOFT for the treatment of medical conditions (other than OCD) in this age group has not been satisfactorily established.

For the treatment of OCD, ZOLOFT is not recommended for use in children under the age of 6, as the safety and efficacy in children of this age group has not been established.

There is no evidence that ZOLOFT is addictive.

2. What should I know before I use ZOLOFT?

Warnings

Do not use ZOLOFT if:

  • you are allergic to sertraline, or any of the ingredients listed at the end of this leaflet.
  • Some of the symptoms of an allergic reaction may include:
    - shortness of breath
    - wheezing or difficulty breathing
    - swelling of the face, lips, tongue or other parts of the body
    - rash, itching or hives on the skin.
  • Always check the ingredients to make sure you can use this medicine.
  • you have epilepsy not properly controlled by medication.
  • you are taking another medicine for depression called a monoamine oxidase inhibitor (MAOI) or have been taking it within the last 14 days. Taking ZOLOFT with a MAOI (e.g. Aurorix, Eldepryl, Nardil, Parnate) may cause a serious reaction with a sudden increase in body temperature, extremely high blood pressure and convulsions (fits).
  • you are taking phentermine (used to help weight loss), tryptophan (contained in protein-based foods or dietary proteins), methadone (used to treat drug addiction), medicines used to treat migraine, e.g. sumatriptan (Imigran), dextromethorphan (used as a cough suppressant in cold and 'flu medications), medicines used for pain management such as fentanyl, tapentadol (Palexia), tramadol or pethidine. These medicines can cause an exaggerated response to ZOLOFT.
  • you are taking pimozide (used to treat disturbances in thinking, feeling and behaviour).
  • Ask your doctor or pharmacist if you are not sure if you have been taking one of these medicines.
  • Do not give ZOLOFT to children or adolescents under the age of 18 unless the doctor has prescribed it for the treatment of OCD. Do not give ZOLOFT to children under the age of 6 for the treatment of OCD.

Check with your doctor if you:

  • have any other medical conditions:
    - any other mental illness
    - epilepsy or seizures
    - liver or kidney problems
    - heart conditions causing irregular heartbeats
    - a tendency to bleed more than normal
    - diabetes mellitus
    - glaucoma, an eye condition.
  • are pregnant or intend to become pregnant.
  • are breastfeeding or wish to breastfeed.
  • take any medicines for any other conditions.

Tell your doctor if you have any allergies to any foods, dyes, preservatives or any other medicines.

During treatment, you may be at risk of developing certain side effects. It is important you understand these risks and how to monitor for them. See additional information under Section 6. Are there any side effects?

Pregnancy and breastfeeding

Check with your doctor if you are pregnant or intend to become pregnant.

There have been reports that babies exposed to ZOLOFT and other antidepressants during the third trimester of pregnancy may develop complications immediately after birth, e.g. you may experience heavy vaginal bleeding shortly after birth (postpartum haemorrhage).

Talk to your doctor if you are breastfeeding or intend to breastfeed.

ZOLOFT passes into breast milk and may affect your baby.

Your doctor will discuss the risks and benefits of taking ZOLOFT when pregnant or breastfeeding.

3. What if I am taking other medicines?

Tell your doctor or pharmacist if you are taking any other medicines, including all medicines, vitamins, natural therapies or supplements that you buy without a prescription from your pharmacy, supermarket or health food shop.

Some medicines may interfere with ZOLOFT and affect how it works.

You may need different amounts of your medicines, or you may need to take different medicines. Your doctor will advise you.

Tell your doctor or pharmacist if you are taking any of the following:

  • other medicines for the treatment of depression called monoamine oxidase inhibitors (MAOIs).

Taking ZOLOFT with, or within 14 days of stopping a MAOI may cause a serious reaction with a sudden increase in body temperature, extremely high blood pressure and convulsions.

  • other MAOI drugs such as linezolid, an antibiotic used to treat pneumonia and certain skin infections
  • other medicines for depression, panic disorder, social anxiety disorder or obsessive illnesses (e.g. Prozac, Aropax, Luvox, Cipramil, Efexor XR)
  • lithium (e.g. Lithicarb), a medicine used to treat mood swings
  • other medicines for PMDD (e.g. Prozac)
  • tryptophan (contained in protein-based foods or dietary proteins)
  • phentermine (weight-reducing medicines)
  • dextromethorphan (used in cold and 'flu medicines to suppress cough)
  • medicines for strong pain management such as fentanyl, tapentadol (Palexia), tramadol or pethidine
  • methadone (used to treat drug addiction)
  • other medicines used to relieve pain, swelling and other symptoms of inflammation, including arthritis (e.g. aspirin or NSAIDs such as ibuprofen or diclofenac)
  • pimozide (used to treat disturbances in thinking, feeling and behaviour)
  • St John's wort, a herbal remedy used to treat mood disorders
  • medicines for treating psychotic illness such as clozapine (e.g. Clozaril) which is used to treat schizophrenia
  • medicines for irregular heartbeats (e.g. Tambocor)
  • warfarin (e.g. Marevan, Coumadin) or other medicines that stop the blood from clotting
  • phenytoin (e.g. Dilantin), a medicine used to treat epilepsy
  • sumatriptan (e.g. Imigran), a medicine used to treat migraine
  • diazepam or other medicines that act on the brain or nervous system (e.g. Serepax, Valium)
  • cimetidine, a medicine used to treat reflux and ulcers
  • Medicines used to treat Attention Deficit Hyperactivity Disorder (ADHD) such as dexamphetamine and lisdexamfetamine
  • antibiotics.

You should wait at least 14 days after stopping ZOLOFT before starting any other medicines for depression or obsessive illnesses from the MAOI group, such as Aurorix, Eldepryl, Nardil, and Parnate.

All of the above precautions are important even after you have stopped taking ZOLOFT.

The effects of ZOLOFT may last for some days after you have stopped taking it.

Not all brand names are given for the medicines listed above. Your doctor or pharmacist has more information on these medicines or other medicines to be careful with or avoid while taking ZOLOFT.

If you have not told your doctor or pharmacist about these things, tell them before you start taking ZOLOFT.

Some combinations of medicines may increase the risk of serious side effects and are potentially life-threatening.

Check with your doctor or pharmacist if you are not sure about what medicines, vitamins or supplements you are taking and if these affect ZOLOFT.

4. How do I use ZOLOFT?

When to take ZOLOFT

  • Try to take your tablet at the same time each day, either morning or evening.
  • 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 to take ZOLOFT

  • Swallow the tablets with a glass of water.

How long to take ZOLOFT

  • Most medicines for depression and obsessive illnesses take time to work so do not be discouraged if you do not feel better straight away.
  • It may take 2 to 4 weeks or even longer to feel the full benefit of ZOLOFT.
  • Continue taking ZOLOFT until your doctor tells you to stop.
  • Even when you feel well, you may need to take ZOLOFT for several months or longer.
  • If you have PMDD, your doctor may ask you to take this medicine only at certain times of the month.
  • Do not stop taking ZOLOFT, or change the dose, without first checking with your doctor.
  • 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.
  • Contact your doctor if you experience any worsening of your depression or other symptoms at any time during your treatment.

If you forget to use ZOLOFT

ZOLOFT should be used regularly at the same time each day. If you miss your dose at the usual time, wait until the next day and take your normal dose then.

If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.

Do not take a double dose to make up for the dose you missed.

If you are not sure what to do in this situation, ask your doctor or pharmacist.

If you have trouble remembering to take your medicine, ask your pharmacist for some hints.

  • phone the Poisons Information Centre
    (Australia telephone 13 11 26) for advice, or
  • contact your doctor, or
  • go to the Emergency Department at your nearest hospital.

You should do this even if there are no signs of discomfort or poisoning.

You may need urgent medical attention.

Symptoms of an overdose may include:

  • feeling drowsy
  • nausea, diarrhoea, vomiting
  • fast or irregular heartbeats
  • tremors
  • feeling agitated or dizzy.
5. What should I know while using ZOLOFT?

Things you must do

Tell all doctors, dentists and pharmacists who are treating you that you are taking ZOLOFT.

Tell your doctor or pharmacist that you are taking ZOLOFT if you are about to be started on any new medicines.

Tell your doctor if you become pregnant while taking ZOLOFT.

If you are a woman of child-bearing age, you should avoid becoming pregnant while taking ZOLOFT.

If you are going to have surgery, tell the surgeon or anaesthetist that you are taking this medicine.

It may interact with other medicines used during surgery and cause unwanted side effects.

If you are about to have any urine tests, tell your doctor that you are taking this medicine.

It may interfere with the results of some tests.

Call your doctor straight away if you:

  • have any suicidal thoughts or other mental/mood changes.

A worsening of depressive symptoms including thoughts of suicide or self-harm may occur in the first one or two months of you taking ZOLOFT or when the doctor changes your dose. These symptoms should subside when the full effect of ZOLOFT takes place.

Children, adolescents or young adults under 24 years of age are more likely to experience these effects during the first few months of treatment.

Patients and caregivers should be alert and monitor for these effects.

Signs and symptoms of suicide include:

  • 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 mention of suicide or violence must be taken seriously.

If you or someone you know is demonstrating these warning signs of suicide while taking ZOLOFT, contact your doctor or a mental health professional right away.

Children should have regular check-ups with the doctor to monitor growth and development.

Things you must not do

  • Do not stop taking ZOLOFT, or change the dose, without first checking with your doctor.
  • Do not let yourself run out of tablets over the weekend or on holidays.
  • Suddenly stopping ZOLOFT may cause dizziness, light headedness, numbness, unusual tingling feelings or shakiness.
  • Do not give this medicine to anyone else, even if their symptoms seem similar to yours.
  • Do not take ZOLOFT to treat any other complaints unless your doctor says to.

Driving or using machines

Be careful before you drive or use any machines or tools until you know how ZOLOFT affects you.

Some medicines for depression may affect your ability to drive or operate machinery or do things that could be dangerous if you are not alert.

If you are feeling drowsy or are uncoordinated, be careful that you do not fall over.

ZOLOFT, like other medicines in this class, may increase your risk of bone fracture.

Drinking alcohol

Tell your doctor if you drink alcohol.

Although drinking moderate amounts of alcohol is unlikely to affect your response to ZOLOFT, your doctor may suggest avoiding alcohol while you are taking ZOLOFT.

Looking after your medicine

  • Store below 30°C
  • Keep your tablets in their blister pack until it is time to take them.

Follow the instructions in the carton on how to take care of your medicine properly.

Store it in a cool dry place away from moisture, heat or sunlight; for example, do not store it:

  • in the bathroom or near a sink, or
  • in the car or on window sills.

Keep it where young children cannot reach it.

A locked cupboard at least 1and a half metres above the ground is a good place to store medicines.

Getting rid of any unwanted medicine

If your doctor tells you to stop taking ZOLOFT, you no longer need to use this medicine or it is out of date, take it to any pharmacy for safe disposal.

Do not use this medicine after the expiry date.

6. Are there any side effects?

All medicines can have side effects. If you do experience any side effects, most of them are minor and temporary. However, some side effects may need medical attention.

It can be difficult to tell whether side effects are the result of taking ZOLOFT, effects of your condition or side effects of other medicines you may be taking. For this reason it is

important to tell your doctor of any change in your condition.

Do not be alarmed by the list of side effects. You may not experience any of them.

See the information below and, if you need to, ask your doctor or pharmacist if you have any further questions about side effects.

4 Clinical Particulars

4.9 Overdose

On the evidence available, sertraline has a wide margin of safety in overdose. Overdoses in adults of 700 to 2100 mg have not resulted in serious symptoms. Ingestion of 4000 mg resulted in seizures in an adolescent. The largest known ingestion is 13.5 g with recovery reported. Another overdose of 2.5 g of sertraline alone resulted in death. Overdosage of 400 and 500 mg in two children have resulted in serotonin syndrome.
Signs and symptoms. Symptoms of overdose include serotonin mediated side effects, such as electrocardiogram QT prolonged, TdP (see Section 4.4 Special Warnings and Precautions for Use; Section 4.5 Interactions with Other Medicines and Other Forms of Interactions; Section 5.1 Pharmacodynamic Properties, Clinical trials), somnolence, gastrointestinal disturbances (such as nausea, diarrhoea and vomiting), tachycardia, tremor, agitation and dizziness. Other important adverse events reported with sertraline overdose (single or multiple drugs) include bradycardia, bundle branch block, coma, convulsions, delirium, hallucinations, hypertension, hypotension, manic reaction, pancreatitis, QT-interval prolongation, stupor and syncope. Hyperthermia, increased respirations and cutaneous vasodilation have also been reported. Minor ECG abnormalities, palpitations, prolonged tachycardia and increased pulse rate have also been reported following paediatric overdose. Seizures have been reported rarely. Serotonin syndrome may result following significant overdose and onset may be delayed. A death due to asthma exacerbation has been reported following sertraline overdose.
Deaths have been reported involving overdoses of sertraline, primarily in combination with other drugs and/or alcohol. Therefore, any overdosage should be treated aggressively.
Elevated liver enzymes and elevated creatine phosphokinase levels have been noted following acute overdose. Hyponatraemia secondary to SIADH has been reported following overdose and has been severe enough to cause seizures.
Treatment of overdosage. In managing overdosage, consider the possibility of multiple drug involvement. Treatment should consist of those general measures employed in the management of overdosage with any antidepressant. Cardiac and vital signs monitoring is recommended along with general symptomatic and supportive measures. Establish and maintain an airway, ensure adequate oxygenation and ventilation, if necessary. Patients should be monitored for potential cardiovascular, gastrointestinal, or hepatic abnormalities. Also monitor for signs/ symptoms of serotonin syndrome (mental status changes, hyperthermia, myoclonus, autonomic instability, high CK levels) and possible seizures.
There are no specific antidotes for sertraline. Activated charcoal should be considered in treating overdose and is most effective when administered within one hour of ingestion. In patients who are not fully conscious or have impaired gag reflex, consideration should be given to administering activated charcoal via nasogastric tube once the airway is protected. Routine use of a cathartic with activated charcoal is not recommended as there is no evidence that cathartics reduce drug absorption and cathartics are known to cause adverse effects, such as nausea, vomiting, abdominal cramps, electrolyte imbalances and, occasionally, hypotension.
Induction of emesis is not recommended because of the potential for CNS depression and seizures. Due to the large volume of distribution of sertraline, forced diuresis, dialysis, haemoperfusion and exchange transfusion are unlikely to be of benefit.
For information on the management of overdose, contact the Poison Information Centre on 131126 (Australia).

5 Pharmacological Properties

5.3 Preclinical Safety Data

Genotoxicity. Sertraline had no genotoxic effects, with or without metabolic activation, based on the following assays; bacterial mutation assay; mouse lymphoma mutation assay; and tests for cytogenetic aberrations in vivo in mouse bone marrow and in vitro in human lymphocytes.
Carcinogenicity. The carcinogenic potential of sertraline has not been fully elucidated. Lifetime carcinogenicity studies were carried out in CD-1 mice and Long-Evans rats (at doses up to 40 mg/kg), giving rise to plasma drug exposure levels similar to or slightly higher than that achieved following the maximum recommended human dose of 200 mg. There was a dose related increase in the incidence of liver adenomas in male mice receiving sertraline at 10 mg/kg to 40 mg/kg. No increase was seen in female mice or in rats of either sex receiving the same treatments, nor was there an increase in hepatocellular carcinomas. Liver adenomas have a variable rate of spontaneous occurrence in the CD-1 mouse and are of unknown significance to humans. There was an increase in follicular adenomas of the thyroid in female rats receiving sertraline at 40 mg/kg; this was not accompanied by thyroid hyperplasia. While there was an increase in uterine adenocarcinomas in rats receiving sertraline at 10 mg/kg to 40 mg/kg compared to placebo controls, this effect was not clearly drug related.
