What is PAROXETINE SYNTHON used for?
The name of your medicine is PAROXETINE SYNTHON; it is also known as paroxetine. PAROXETINE SYNTHON belongs to a group of medicines called selective serotonin reuptake inhibitor (SSRI) antidepressants. They are thought to work by their action on brain chemicals called amines which are involved in controlling mood.
Depression is longer lasting or more severe than the 'low moods' that everyone has from time to time. 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. You may feel low in spirit, lose interest in usual activities, be unable to enjoy life, have poor appetite or over eat, have disturbed sleep, often waking up early, low energy and feel guilty over nothing. PAROXETINE SYNTHON corrects the chemical imbalance and so helps relieve the symptoms of depression.
PAROXETINE SYNTHON may also be used to treat irrational fears or obsessional behaviour. These can also be due to chemical imbalance in parts of the brain.
PAROXETINE SYNTHON may also be used to help prevent panic attacks.
PAROXETINE SYNTHON may also be used to treat patients who may avoid and/or are fearful of social situations.
PAROXETINE SYNTHON may also be used to treat patients who have excessive anxiety and worry, and who feel irritable, restless, and/or tense in the muscles.
PAROXETINE SYNTHON may also be used to treat repetitive and distressing recollections of a past traumatic event.
Your doctor may decide that you should continue to use PAROXETINE SYNTHON for some time, even when you have overcome your problem. This should prevent the problem from returning.
Your doctor may have prescribed PAROXETINE SYNTHON for another use.
Ask your doctor if you have questions about why PAROXETINE SYNTHON has been prescribed for you.
Before you take it
Antidepressants can increase suicidal thoughts and actions in some children and adolescents younger than 18 years of age. But suicidal thoughts and actions can also be caused by depression, a serious medical condition that is commonly treated with antidepressants. Thinking about killing yourself or trying to kill yourself is called suicidality or being suicidal.
Antidepressants are used to treat depression and other illnesses. Depression and other illnesses can lead to suicide.
In some children and adolescents, treatment with an antidepressant increases suicidal thinking or actions. It is important to discuss all the risks of treating depression and also the risks of not treating it. You should discuss all treatment choices with your doctor, not just the use of antidepressants.
Patients (and caregivers of patients) need to monitor for any worsening of their condition and/or the emergence of thoughts of suicide or suicidal behaviour or thoughts of harming themselves and to seek medical advice immediately if these symptoms present. (See Use In Children and Adolescents).

Family and caregivers of children and adolescents being treated with antidepressants for major depressive disorder or for any other condition (psychiatric or non-pyschiatric) need to monitor them for the emergence of agitation, irritability, unusual changes in behaviour, as well as the emergence of thoughts of suicide, and to report such symptoms immediately to their doctor. It is particularly important that monitoring be undertaken during the initial few months of antidepressant treatment or at times of dose increase or decrease
