1. What is Seroxat and what is it used for

Seroxat is used to treat adults with depression and/or anxiety disorders.

Anxiety disorders for which Seroxat is used include: obsessive-compulsive disorder (recurring, obsessive thoughts with uncontrolled behavior), panic disorder (panic attacks, including those caused by agoraphobia, which is a 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 feeling of anxiety or nervousness).
Seroxat belongs to a group of medicines called selective serotonin reuptake inhibitors (SSRIs). It is not fully understood how Seroxat and other SSRIs work, but they may increase the level of serotonin in the brain. Proper treatment of depression and anxiety disorders is important for the patient to feel better.

2. Important information before taking Seroxat

When not to take Seroxat:

• If the patient is taking monoamine oxidase inhibitor (MAOI) medicines(including moclobemide and methylene blue) or has taken them in the last two weeks. The doctor will advise the patient on how to start taking Seroxat after stopping MAOIs.
• If the patient is taking antipsychotic medicines, such as thioridazine or pimozide.
• If the patient is allergicto paroxetine or any of the other ingredients of this medicine (listed in section 6). If any of the above situations apply to the patient, they should contact their doctor without taking Seroxat.

Warnings and precautions

Before starting Seroxat, the patient should discuss the following with their doctor or pharmacist:

• Is the patient taking any other medicines (see Seroxat and other medicineslater in the leaflet)?
• Is the patient taking tamoxifen for breast cancer? Seroxat may reduce the effectiveness of tamoxifen, and the doctor may recommend a different antidepressant.
• Does the patient have kidney, liver, or heart problems?
• Does the patient have abnormal heart rhythm (ECG) known as QT interval prolongation?
• Is there a family history of QT interval prolongation, heart disease such as heart failure, low heart rate, or low potassium or magnesium levels?
• Does the patient have epilepsy or a history of seizures?
• Has the patient ever had episodes of mania (excessive activity or racing thoughts)?
• Is the patient receiving electroconvulsive therapy?
• Has the patient ever had bleeding or is taking other medicines that may increase the risk of bleeding (including blood thinners such as warfarin, antipsychotic medicines such as perphenazine or clozapine, tricyclic antidepressants, or non-steroidal anti-inflammatory drugs (NSAIDs) such as aspirin, ibuprofen, celecoxib, etodolac, diclofenac, or 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 fertilitylater in the leaflet)?
• Is the patient under 18 years old (see Children and adolescents under 18 years oldlater in the leaflet)?

If the answer is YES to any of the above questionsand the patient has not yet consulted their doctor, they should go back to their doctorand ask how to take Seroxat.

Children and adolescents under 18 years old

Seroxat should not be used in children and adolescents under 18 years old.

Patients under 18 years old are at increased risk of side effects such as suicidal thoughts, suicidal attempts, and hostility (especially aggression, rebellious behavior, and signs of anger) when taking Seroxat. If the doctor has prescribed Seroxat to a patient under 18 years old and there are concerns, the patient should consult their doctor. If these symptoms occur or worsen while taking Seroxat, the patient should inform their doctor. Additionally, there is currently no data on the long-term safety of Seroxat regarding growth, maturation, and cognitive and behavioral development in this age group.
In studies of Seroxat in patients under 18 years old, common side effects that occurred with a frequency of less than 1 in 10 included increased suicidal thoughts and attempts, intentional self-harm, hostility, aggressive behavior, or unfriendly behavior, loss of appetite, tremors, abnormal sweating, excessive activity (excess energy), restlessness, emotional instability (including tearfulness and mood changes), 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.
Some patients under 18 years old in these studies experienced withdrawal symptoms when stopping Seroxat. These symptoms were very similar to those observed in adults after stopping Seroxat (see section 3). Additionally, in patients under 18 years old, common side effects (occurring with a frequency of less than 1 in 10) included abdominal pain, feeling nervous, and emotional instability (including tearfulness, mood changes, self-harm, suicidal thoughts, and suicidal attempts).

Suicidal thoughts and worsening of depression or anxiety disorder

In patients with depression and/or anxiety disorders, suicidal thoughts or self-harm may sometimes occur. They may be more frequent at the start of antidepressant treatment, as it may take some time, usually about two weeks, for the medicines to start working, and sometimes even longer.
For the patient, such thoughts may occur more frequently:

• If the patient has had suicidal thoughts or self-harm before.
• If the patient is a young adult. Clinical studies have shown an increased risk of suicidal behavior in adults (under 25 years old) with mental disorders who were treated with antidepressants. If suicidal thoughts or self-harm occur at any time, the patient should contact their doctor or the nearest emergency department immediately. It may be helpful to inform a relative or friend about the depression or anxiety disorder and ask them to read this leaflet. The patient may ask them to tell them if they notice that the depression or anxiety disorder is getting worse or if there are worrying changes in their behavior.

Important side effects observed during Seroxat treatment

In some patients taking Seroxat, a condition called akathisia may develop.
They may feel anxious and unable to sit or stand still. In other patients, a condition called serotonin syndrome or neuroleptic malignant syndrome may occur, with symptoms including feeling highly agitated or confused, disoriented, anxious, hot, sweaty, trembling, shaking, hallucinations (seeing or hearing strange things), muscle stiffness, sudden muscle contractions, or rapid heartbeat. These symptoms can 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 side effects of Seroxat can be found in section 4.
Medicines like Seroxat (SSRIs) may cause sexual function disorders (see section 4). In some cases, these symptoms have persisted after stopping treatment.

Seroxat and other medicines

Some medicines may affect the action of Seroxat or increase the risk of side effects. Seroxat may also affect the action of other medicines. These medicines include:

• Monoamine oxidase inhibitors (MAOIs), such as moclobemide and methylene blue - see section "When not to take Seroxat"
• Medicines known to affect the heart's electrical activity (e.g., antipsychotic medicines like thioridazine or pimozide) - see section "When not to take Seroxat"
• Aspirin, ibuprofen, or other non-steroidal anti-inflammatory drugs (NSAIDs) such as celecoxib, etodolac, diclofenac, and meloxicam, used for pain and inflammatory conditions
• Tramadol, buprenorphine, and pethidine, pain relief medicines
• Buprenorphine in combination with naloxone, used for opioid dependence substitution treatment
• Triptans, such as sumatriptan, used for migraine treatment
• Other antidepressant medicines, called SSRIs and tricyclic antidepressants, such as clomipramine, nortriptyline, and desipramine
• Dietary supplementcalled tryptophan;
• Mivacurium and suxamethonium (used for general anesthesia)
• Medicines such as lithium, risperidone, perphenazine, or clozapine (called antipsychotic medicines) used for certain mental disorders
• Fentanyl, a medicine used during anesthesiaand for chronic pain treatment
• The combination of fosamprenavir and ritonavir, used for HIV infection treatment
• St. John's Wort, used as a depression aid
• Phenobarbital, phenytoin, sodium valproate, or carbamazepine, used for seizure or epilepsy treatment
• Atomoxetine, used for attention deficit hyperactivity disorder (ADHD) treatment
• Procyclidine, used for Parkinson's disease treatment
• Warfarin or other medicines (called anticoagulants) used for blood thinning
• Propafenone, flecainide, and medicines used for irregular heartbeat treatment
• Metoprolol, a beta-blocker used for high blood pressure and heart problems
• Pravastatin, used for high cholesterol treatment
• Rifampicin, used for tuberculosis treatment
• Linezolid, an antibiotic
• Tamoxifen, used for breast cancer treatment.

If the patient is currently taking or has recently taken any of these medicinesand has not yet discussed this with their doctor, they should contact their doctor againand ask how to proceed. The dose of the medicine may need to be changed or a different medicine may be necessary.

The patient should tell their doctor or pharmacist about all medicines they are currently taking or

plan to take, including those that are available without a prescription.

Seroxat with food, drink, and alcohol

The patient should not drink alcohol while taking Seroxat. Alcohol may increase the symptoms of the illness or the side effects of the medicine. Taking Seroxat in the morning with food may reduce the likelihood of nausea.

Pregnancy, breastfeeding, and fertility

If the patient is pregnant or breastfeeding, or thinks they may be pregnant or plans to have a baby, they should consult their doctor or pharmacist before taking this medicine.
There have been reports suggesting that children whose mothers took Seroxat during the first few months of pregnancy may have an increased risk of congenital malformations, particularly heart defects. In the general population, about 1 in 100 children is born with a heart defect. This number increases to 2 in 100 children if the mother takes Seroxat. The doctor will discuss with the patient whether it is better for them to switch to a different medicine or gradually stop taking Seroxat during pregnancy. In some cases, the doctor may also suggest that it is better for the patient to continue taking Seroxat.

The patient should ensure that their midwife or doctor is informed that they are taking

Seroxat. Taking Seroxat late in pregnancy may increase the risk of serious bleeding from the vagina, occurring shortly after delivery, especially if the patient has a history of bleeding disorders. If the patient is taking Seroxat, they should inform their doctor or midwife so that they can provide appropriate advice. Medicines like Seroxat, when taken during pregnancy, especially in the last few months, may increase the risk of a condition called persistent pulmonary hypertension in the newborn (PPHN).
In PPHN, the blood pressure in the blood vessels between the heart and lungs of the baby is too high. If the patient takes Seroxat during the last 3 months of pregnancy, the newborn may also experience other symptoms, usually within the first 24 hours after birth, including:

• Difficulty breathing;
• Blue-tinged skin or unstable body temperature;
• Blue-tinged lips;
• Vomiting or difficulty feeding;
• Tiredness, difficulty sleeping, or increased crying;
• Stiff or floppy muscles;
• Tremors, jitteriness, or seizures;
• Increased reflexes. If the baby experiences any of these symptoms after birth or if there are concerns about the baby's health, the patient should contact their doctor or midwife for advice.

Seroxat may pass into breast milk in very small amounts. If the patient is taking Seroxat, they should consult their doctor before breastfeeding. The doctor, together with the patient, can decide whether to breastfeed while taking Seroxat.
In animal studies, paroxetine has been shown to reduce sperm quality. This could theoretically affect fertility, but the impact on human fertility has not been determined.

Driving and using machines

Possible side effects of Seroxat include dizziness, disorientation, drowsiness, and vision disturbances. If the patient experiences any of these side effects, they should not drive or operate machinery.

Seroxat contains sodium

This medicine contains less than 1 mmol (23 mg) of sodium per tablet, which means it is essentially "sodium-free".

3. How to take Seroxat

This medicine should always be taken as directed by the doctor. If the patient is unsure, they should consult their doctor or pharmacist.
Sometimes taking one tablet does not ensure the patient is taking the full recommended dose of the medicine. The following table indicates how many Seroxat tablets the patient should take 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
Usual doses for different conditions are given below.

The doctor will advise the patient on the initial dose of Seroxat. Most patients start to feel better after a few weeks. If there is no improvement after this time, the patient should consult their doctor. The doctor may decide to gradually increase the dose by 10 mg until the maximum daily dose is reached.

The tablets should be taken in the morning with food.

Swallow the tablets with water.

Do not chew.

The doctor will discuss with the patient how long they should take the tablets. Treatment may last for several months or even longer.

Elderly patients

The maximum dose for patients over 65 years old is 40 mg per day.

Patients with liver or kidney disease

The doctor may recommend a lower dose of Seroxat for patients with liver disease or severe kidney disease.

Taking more Seroxat than prescribed

The patient should never take more tablets than prescribed by their doctor. If the patient (or someone else) has taken too many Seroxat tablets, they should immediately inform their doctor or contact the nearest emergency department. They should show the doctor the packaging of the tablets.
As a result of overdosing on Seroxat, the patient may experience side effects described in section 4: Possible side effectsor the following symptoms: fever, involuntary muscle contractions.

Missing a dose of Seroxat

The medicine should be taken at the same time every day.
If the patient misses a dose and remembers before going to bed, they should take it immediately. The next day, they should take the dose as usual.
If the patient remembers in the night or the next day that they missed a dose, they should not take the missed dose. The patient may experience withdrawal symptoms, but they should resolve quickly after taking the next dose at the usual time.
The patient should not take a double dose to make up for the missed dose.

What to do if there is no improvement

Seroxat does not relieve symptoms immediately- all antidepressant medicines take some time to start working. 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 the patient does not feel better after a few weeks of treatment, they should consult their doctor for advice. The doctor should recommend that the patient have a follow-up visit after a few weeks of starting treatment for the first time. The patient should inform their doctor if they have not started to feel better.

Stopping Seroxat treatment

The patient should not stop taking Seroxat without consulting their doctor

When stopping Seroxat, the doctor will help the patient gradually reduce the dose over a few weeks or months - this should limit the risk of withdrawal symptoms. One way to do this is to gradually reduce the dose of Seroxat by 10 mg per week. In most patients, withdrawal symptoms are mild and resolve on their own within two weeks. In some patients, symptoms may be more severe or may last longer.
If the patient experiences withdrawal symptoms after stopping Seroxat, the doctor may decide that the patient should stop taking the medicine more slowly. If the patient experiences severe symptoms when stopping Seroxat, they should contact their doctor. The doctor may recommend restarting the tablets and stopping them more slowly.

Even if the patient experiences withdrawal symptoms, it is still possible to stop taking Seroxat
