1. What Seroxat is and what it is used for

Seroxat is used in the treatment of adults with depression and (or) anxiety disorders.
Anxiety disorders for which Seroxat is used include: obsessive-compulsive disorder (recurring, obsessive thoughts with uncontrollable behaviour), panic disorder (panic attacks, including those associated with agoraphobia, which is fear of open spaces), social phobia (fear or avoidance of social situations), post-traumatic stress disorder (anxiety caused by a traumatic event), and generalized anxiety disorder (generalized feelings of anxiety or nervousness).
Seroxat belongs to a group of medicines called selective serotonin reuptake inhibitors (SSRIs). The exact way in which Seroxat and other SSRIs work is not fully understood, but they may increase the concentration of serotonin in the brain. Proper treatment of depression and anxiety disorders is important to help the patient feel better.

2. Important information before using Seroxat

When not to use Seroxat:

• If the patient is taking medicines called monoamine oxidase inhibitors (MAO inhibitors, including moclobemide and methylene blue chloride) or has taken them within the last two weeks. The doctor will advise the patient on how to start taking Seroxat after stopping MAO inhibitors.
• If the patient is taking antipsychotic medicines such as thioridazine or pimozide.
• If the patient is allergic to paroxetine or any of the other ingredients of this medicine (listed in section 6). If any of the above situations apply to the patient, contact the treating doctor and do not take Seroxat.

Warnings and precautions
Before starting treatment with Seroxat, discuss the following with your doctor or pharmacist:

• Is the patient taking any other medicines? (See Seroxat and other medicines later in this leaflet)?
• Is the patient taking tamoxifen for the treatment of breast cancer? Seroxat may reduce the effectiveness of tamoxifen, and therefore the treating doctor may recommend another antidepressant.
• Does the patient have kidney, liver, or heart problems?
• Does the patient have abnormal heart conduction on electrocardiogram (ECG), known as QT interval prolongation?
• Does the patient have a family history of QT interval prolongation, heart disease such as heart failure, slow heart rate, or low potassium or magnesium levels?
• Does the patient have epilepsy or a history of seizures?
• Has the patient ever experienced episodes of mania (excessively active behavior or racing thoughts)?
• Is the patient receiving electroconvulsive therapy?
• Has the patient had bleeding episodes in the past or is taking other medicines that may increase the risk of bleeding (including blood-thinning medicines such as warfarin, antipsychotics such as perphenazine or clozapine, tricyclic antidepressants, pain and anti-inflammatory medicines known as non-steroidal anti-inflammatory drugs (NSAIDs), such as acetylsalicylic acid, ibuprofen, celecoxib, etodolac, diclofenac, meloxicam)?
• Does the patient have diabetes?
• Is the patient on a low-sodium diet?
• Does the patient have glaucoma (increased pressure in the eye)?
• Is the patient pregnant or planning to become pregnant? (See Pregnancy, breastfeeding and fertility later in this leaflet)
• Is the patient under 18 years of age? (See Children and adolescents under 18 years of age later in this leaflet)

If the answer is YES to any of the above questions and the patient has not yet consulted
their doctor, the patient should see their doctor again to discuss how to take
Seroxat.
Children and adolescents under 18 years of age
Seroxat must not be used in children and adolescents under 18 years of age. Patients
under 18 years of age are at increased risk of adverse effects such as suicidal attempts, suicidal thoughts, and hostility (particularly aggression, oppositional behaviors, and anger) while taking Seroxat. If the doctor has prescribed Seroxat to a patient under 18 years of age and there are any doubts, contact the treating doctor. If the symptoms listed above occur or worsen during treatment with Seroxat, inform the doctor. In addition, there is currently no data on the long-term safety of Seroxat regarding growth, maturation, cognitive development, and behavioral development in this age group.
In clinical studies of Seroxat in patients under 18 years of age, common adverse reactions occurring in less than 1 in 10 patients included: increased frequency of suicidal thoughts and suicide attempts, deliberate self-harm, hostility, aggressive or hostile behaviors, loss of appetite, tremor, abnormal sweating, excessive activity (exhibiting excess energy), restlessness, emotional lability (including tearfulness and mood swings), and unusual bruising or bleeding (such as nosebleeds).
These studies also showed that such symptoms occurred, although less frequently, in children and adolescents taking placebo (sugar pills) instead of Seroxat.
In some patients under 18 years of age in these studies, symptoms related to discontinuation of Seroxat occurred. These symptoms were very similar to those observed in adults after stopping Seroxat (see section 3). Additionally, in patients under 18 years of age, abdominal pain, feeling of agitation, and emotional lability (including tearfulness, mood swings, self-harm attempts, suicidal thoughts, and suicide attempts) were also common (occurring in less than 1 in 10 patients).
Suicidal thoughts and worsening of depression or anxiety symptoms
Patients with depression and/or anxiety disorders may sometimes experience thoughts of self-harm or suicidal thoughts. These may be intensified at the beginning of treatment with antidepressants, as it may take some time—usually about two weeks—before the medicines start to work, and sometimes even longer.
Such thoughts may be more frequent in the patient if:

• The patient previously had suicidal thoughts or thoughts of self-harm.
• The patient is a young adult. Clinical studies have shown an increased risk of suicidal behavior in adults under 25 years of age with psychiatric disorders who were treated with antidepressants. If thoughts of self-harm or suicide occur at any time, contact the doctor or the nearest hospital emergency department immediately.

It may be helpful to inform a relative or friend about the patient's depression or
anxiety disorder and ask them to read this leaflet. The patient may ask them to inform him or her if they notice worsening depression or anxiety, or any worrying changes in behavior.
Important adverse effects observed during treatment with Seroxat
In some patients taking Seroxat, symptoms called akathisia may develop.
They then feel restless and unable to sit or stand still. In other patients, a condition called serotonin syndrome or neuroleptic malignant syndrome may develop, in which patients experience some or all of the following symptoms: intense restlessness or irritability, confusion (disorientation), anxiety, fever, sweating, tremor, chills, hallucinations (strange visions or hearing strange sounds), muscle stiffness, sudden muscle contractions, or rapid heartbeat. Symptoms may worsen, leading to loss of consciousness. If the patient notices any of these symptoms, they should contact their doctor. More information about these or other adverse effects of Seroxat is provided in section 4.
Medicines such as Seroxat (so-called SSRIs) may cause sexual dysfunction (see section 4). In some cases, these symptoms persisted after discontinuation of treatment.
Seroxat and other medicines
Some medicines may affect the action of Seroxat or increase the risk of adverse effects. Seroxat may also affect the action of other medicines. These include:

• Medicines called monoamine oxidase inhibitors (MAO inhibitors, including moclobemide and methylene blue chloride) – see section When not to use Seroxat
• Medicines known to increase the risk of changes in electrical activity of the heart (e.g., antipsychotics such as thioridazine or pimozide) – see section When not to use Seroxat
• Acetylsalicylic acid, ibuprofen, or other medicines called non-steroidal anti-inflammatory drugs (NSAIDs), such as celecoxib, etodolac, diclofenac, and meloxicam, used for pain and inflammatory conditions
• Tramadol, buprenorphine, and pethidine, painkillers
• Buprenorphine in combination with naloxone, used in opioid addiction replacement therapy
• Medicines called triptans, such as sumatriptan, used for migraine treatment
• Other antidepressants, known as SSRIs and tricyclic antidepressants, such as clomipramine, nortriptyline, and desipramine
• A dietary supplement called tryptophan
• Mivacurium and suxamethonium (used for general anesthesia)
• Medicines such as lithium, risperidone, perphenazine, clozapine (called antipsychotics) used to treat certain psychiatric disorders
• Fentanyl, a medicine used during anesthesia and for chronic pain treatment
• The combination of fosamprenavir and ritonavir, used for treatment of human immunodeficiency virus (HIV) infection
• St. John's wort, used as an adjunct in depression
• Phenobarbital, phenytoin, sodium valproate, or carbamazepine used to treat seizures or epilepsy
• Atomoxetine, used for treatment of attention deficit hyperactivity disorder (ADHD)
• Procyclidine, used to treat tremor, particularly in Parkinson's disease
• Warfarin or other medicines (called anticoagulants) used to thin the blood
• Propafenone, flecainide, and medicines used to treat irregular heartbeat
• Metoprolol, a beta-blocker used to treat high blood pressure and heart problems
• Pravastatin, used to treat elevated cholesterol levels
• Rifampicin, used to treat tuberculosis and acne
• Linezolid – an antibiotic
• Tamoxifen, used for breast cancer treatment.

If the patient is currently taking or has recently taken any of the listed medicines and
has not yet discussed this with their doctor, they should contact their doctor again to
ask what action should be taken. The dose of the medicine may need to be changed or another medicine may need to be taken.
Tell your doctor or pharmacist about all medicines you are currently taking or have recently taken, including medicines you plan to take, and those available without a prescription.
Seroxat with food, drink, and alcohol
Do not consume alcohol while taking Seroxat. Alcohol may worsen symptoms of the illness or adverse effects. Taking Seroxat in the morning with food reduces the likelihood of nausea.
Pregnancy, breastfeeding and fertility
If the patient is pregnant or breastfeeding, suspects she may be pregnant, or is planning to have a child, she should consult her doctor or pharmacist before using this medicine.
There are some reports indicating that congenital developmental abnormalities, particularly heart defects, may occur in babies whose mothers took Seroxat during the first few months of pregnancy.
In the general population, about 1 in 100 babies is born with a heart defect. This number increases to 2 in 100 babies if the mother took Seroxat. The doctor will decide together with the patient whether it is better during pregnancy to switch to another medicine or gradually discontinue Seroxat. In certain circumstances, the doctor may also suggest that it is better for the patient to continue taking Seroxat.
Ensure that the midwife or doctor is informed that the patient is taking Seroxat. Taking Seroxat towards the end of pregnancy may increase the risk of serious vaginal bleeding shortly after delivery, especially if the patient has a history of bleeding disorders. If the patient is taking Seroxat, she should inform her doctor or midwife so they can provide appropriate advice. Medicines such as Seroxat taken during pregnancy, especially in the later stages, may increase the risk of serious complications in the newborn, known as persistent pulmonary hypertension of the newborn (PPHN).
In PPHN, blood pressure in the blood vessels between the baby's heart and lungs is too high. If the patient takes Seroxat during the last three months of pregnancy, other symptoms may also occur in the newborn, usually within the first 24 hours after birth. These include:

• Breathing difficulties
• Bluish skin or unstable body temperature
• Bluish lips
• Vomiting or difficulty feeding properly
• Tiredness, difficulty sleeping, or increased crying
• Stiff or floppy muscles
• Tremors, jitteriness due to agitation, or seizures
• Exaggerated reflexes. If any of these symptoms occur in the baby after birth or if there are concerns about the baby's health, contact the doctor or midwife for advice.

Seroxat may pass into breast milk in very small amounts. If the patient is taking
Seroxat, she should consult her doctor before starting breastfeeding. The doctor and the patient may decide together that breastfeeding is acceptable while taking Seroxat.
Animal studies have shown that paroxetine reduces sperm quality. This could theoretically affect fertility, but the effect on human fertility has not yet been established.
Driving and operating machinery
Possible adverse effects caused by Seroxat include: dizziness, disorientation, drowsiness, and vision disturbances. If such adverse effects occur, the patient should not drive or operate machinery.
Seroxat contains sodium
This medicine contains less than 1 mmol (23 mg) of sodium per tablet, meaning the medicine is considered "sodium-free".

3. How to take Seroxat

This medicine should always be taken exactly as your doctor has advised. If in doubt,
consult your doctor or pharmacist.
Sometimes taking one tablet does not provide the full recommended dose of the medicine. The table
below indicates how many Seroxat tablets should be taken for a given dose.
Dose Number of tablets to take
10 mg half a tablet
20 mg one tablet
30 mg one and a half tablets
40 mg two tablets
50 mg two and a half tablets
60 mg three tablets
The usual doses used for different conditions are given below.

The prescribing doctor will advise at which dose of Seroxat treatment should be started. Most
patients begin to feel better after a few weeks. If there is no improvement by this time,
you should consult your doctor. The doctor may decide to gradually increase the dose by 10
mg until the maximum daily dose is reached.
Tablets should be taken in the morning, with food.
Swallow with water.
Do not chew.
The prescribing doctor will discuss with the patient how long the tablets should be taken. Treatment may last
for several months or even longer.
Elderly patients
The maximum dose for patients over 65 years of age is 40 mg per day.
Patients with liver or kidney disease
For patients with liver disease or severe kidney disease, the doctor may recommend a lower dose of
Seroxat than normally used.
Taking more Seroxat than prescribed
Never take more tablets than your doctor has prescribed. If a patient (or another person)
has taken too many Seroxat tablets, contact your doctor immediately or
go to the nearest hospital emergency department. Show them the tablet packaging.
Symptoms described in section 4: Possible side effects, or the following symptoms, may occur as a result of Seroxat overdose:
fever, involuntary muscle contractions.
Missing a dose of Seroxat
The medicine should be taken at the same time each day.
If a dose is missed and you remember before going to bed, take it immediately.
The next day, take your usual dose as normal.
If you remember during the night or the following day that you missed a dose, do not
take the missed dose. Withdrawal symptoms may occur, but they should quickly subside after taking the next dose at the usual time.
Do not take a double dose to make up for a missed dose.
What to do if there is no improvement
Seroxat does not relieve symptoms of illness immediately – all antidepressant medicines
begin to work only after some time. Some patients start to feel better after a few weeks,
while others may take longer. Some patients taking antidepressants may feel worse before they start to feel better. If you do not feel better after a few weeks of treatment, you should consult your doctor for advice. The doctor should schedule a follow-up visit a few weeks after starting the medicine for the first time. Inform your prescribing doctor if you have not started to feel better.
Stopping treatment with Seroxat
Do not stop taking Seroxat unless your doctor advises you to do so.
When discontinuing Seroxat, your doctor will help you gradually reduce the dose over
several weeks or months – this should reduce the likelihood of withdrawal symptoms.
One way is to gradually reduce the patient's dose of Seroxat by 10 mg per week.
In most patients, withdrawal symptoms are mild and resolve on their own within two weeks.
However, in some patients, symptoms may be more severe or may persist longer.
If withdrawal symptoms occur after stopping Seroxat tablets, the doctor may
decide that the patient should taper off the medicine more slowly. If severe symptoms occur during
discontinuation of Seroxat, contact your doctor. The doctor may recommend resuming the tablets and tapering them more slowly.
Even if withdrawal symptoms occur, it is still possible to discontinue treatment with Seroxat.
Possible withdrawal symptoms occurring after stopping treatment
Studies show that 3 out of 10 patients notice one or more withdrawal symptoms when discontinuing Seroxat therapy. Some of these symptoms occur more frequently than others.
Common side effects (occurring in up to 1 in 10 patients):

• Dizziness, unsteadiness, or difficulty maintaining balance
• Tingling sensation, burning sensation, and (less commonly) electric shock-like sensations, including in the head, and ringing, buzzing, whistling, or other persistent noise in the ears (tinnitus)
• Sleep disturbances (vivid dreams, nightmares, insomnia)
• Feeling of anxiety
• Headaches. Uncommon side effects (occurring in up to 1 in 100 patients):
• Nausea
• Sweating (including night sweats)
• Feeling restless or agitated
• Tremor
• Feeling disoriented
• Diarrhea (loose stools)
• Emotional lability or irritability
• Visual disturbances
• Palpitations or increased heart rate (palpitations).

If you are concerned about withdrawal symptoms after stopping Seroxat,
contact your doctor.
If you have any further questions about using this medicine, consult your doctor or pharmacist.
