What this medicine is used for

The name of your medicine is GenRx Paroxetine. It contains the active ingredient, paroxetine (as paroxetine hydrochloride).

It is used to treat:

  • depression
  • Obsessive Compulsive Disorder (OCD)
  • panic disorder
  • social anxiety disorder or social phobia
  • generalised anxiety disorder
  • post-traumatic stress disorder.

It is also used to prevent the symptoms of depression, Obsessive Compulsive Disorder and panic disorder from coming back.

Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed this medicine for another reason.

This medicine is available only with a doctor's prescription.

How it works

Paroxetine belongs to a group of medicines called selective serotonin reuptake inhibitors (SSRIs). They are thought to work by their action on brain chemicals called amines which are involved in controlling mood.

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, not interested in usual 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. Paroxetine corrects the chemical imbalance and so helps to relieve the symptoms of depression, and stops them coming back.

Paroxetine is thought to have a similar action when it used to treat or prevent irrational fears or obsessional behaviour or panic attacks, and when it is used to treat patients who may avoid and/or are fearful of social situations, have excessive anxiety and worry, who feel irritable, restless and/or tense in the muscles, or who experience repeated and distressing recollections of a past traumatic event.

There is no evidence that this medicine is addictive

Clinical experience has shown that paroxetine should not affect the ability to drive or operate machinery. However, make sure you know how paroxetine affects you before driving or operating machinery, as it can make some people drowsy or dizzy or affect their concentration.

Use in children

Paroxetine is not recommended for use in anyone under 18 years of age. It has been shown that the risk of serious side effects such as suicidal thoughts and actions is higher in people under 18.

How to take this medicine

Follow carefully all directions given to you by your doctor or pharmacist carefully. Their instructions may be different to the information in this leaflet.

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.

Do not stop taking your medicine or change your dosage without first checking with your doctor.

The usual dose of paroxetine for depression, social anxiety disorder/social phobia, generalised anxiety disorder or post-traumatic stress disorder is one 20 mg tablet taken once each day. If 20 mg is not working, your doctor may increase the dose slowly by adding 10 mg at a time. The dose should not go above 50 mg per day in adults, or 40 mg per day in elderly people.

The usual dose of paroxetine for obsessions and compulsions or panic attacks is two 20 mg tablets taken once each day. Your doctor should start you on a lower dose and increase the dose slowly by adding 10 mg at a time over several weeks. This may require you to break the tablet in half. The dose should not go above 60 mg per day in adults, or 40 mg per day in elderly people.

If you have kidney or liver problems then the doses may be lower.

How to take it

Swallow the tablets with a glass of water.

The tablets should not be chewed.

When to take it

Take your medicine in the morning, preferably with food.

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.

How long to take it for

Continue taking your medicine for as long as your doctor tells you.

Make sure you have enough to last over weekends and holidays.

Like other drugs of this type, this medicine will not relieve your symptoms straight away. People generally start feeling better in a few weeks or so. 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 your medicine starts to work.

Make sure that you or anyone close to you or caring for you watch for these symptoms in the first few months or treatment or when changing the dose, and that you or your carer 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/other symptoms at any time during your treatment.

Stopping 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 feeling dizzy, sick or anxious; sweating; pins and needles or electric shock feelings, or disturbed sleep.

If you forget to take it

Do not take an extra dose. Wait until the next day and take your dose then.

Do not take a double dose to make up for missed doses. This may increase the chance of unwanted side effects.

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

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. Symptoms of an overdose may include nausea, vomiting, tremor, dilated pupils, dry mouth, sedation, sweating, dizziness, confusion, headache, fast heartbeat and irritability.

While you are taking this medicine

Things you must do

People taking paroxetine may be more likely to think about killing themselves or actually try to do so, especially when paroxetine 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 paroxetine 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 until the full antidepressant effect of the medicine becomes apparent. 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 paroxetine, contact a doctor immediately, or even to 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 self-harm
  • increase in aggressive behaviour, irritability or agitation.

Tell your doctor that you are taking this medicine if:

  • you are about to be started on any new medicine
  • you plan to have any vaccinations or immunisations
  • you become pregnant or plan to breastfeed
  • you are about to have any blood tests
  • you are going to have surgery.

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.

If you are a male and you and your partner have been unsuccessful whilst trying for a baby, tell your doctor.

Some studies have shown that medicines such as paroxetine may affect sperm quality. However the effect goes away if the medicine is stopped.

If you have an accident, and/or break a bone, tell your doctor that you are taking paroxetine, Some antidepressant medicines have been associated with an increased risk of bone fracture.

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.

This will help your doctor to determine the best treatment for you.

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 suddenly, or change the dosage, without first checking with your doctor.

If you have any of these symptoms, do not drive a car; operate machinery, or anything else that could be dangerous.

Be careful when drinking alcohol while you are taking paroxetine. If you drink alcohol, dizziness, drowsiness or impaired concentration may be worse, or your symptoms of depression or anxiety may become worse. Your doctor may suggest avoiding alcohol while you are being treated with this medicine.

You should wait at least 14 days after stopping paroxetine before starting any medicines known as monoamine oxidase inhibitors (MAOIs), such as phenelzine, tranylcypromine and moclobemide. 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.

Some people may have symptoms such as such as feeling dizzy, sick or anxious; sweating; pins and needles or electric shock feelings, or disturbed sleep if paroxetine is stopped, particularly if stopped suddenly.
