How Does It Work?

Paroxetine

Paroxetine is a selective serotonin reuptake inhibitor (SSRI). It inhibits the reuptake of serotonin by presynaptic neurons, increasing the availability of serotonin within the synaptic space. This influences serotonergic neurotransmission in the central nervous system and contributes to its antidepressant and anxiolytic effects.

The clinical benefits of treatment may take several weeks to become apparent.

Dosage Guidelines

The appropriate dose and treatment duration depend on the indication, clinical response, age, tolerability, concurrent medicines, and other individual factors.

The exact dose and treatment duration should follow the approved product information and the recommendation of a qualified healthcare professional.

For oral tablets:

• Take exactly as prescribed.
• Swallow the tablet with sufficient water unless otherwise directed.
• Take it at approximately the same time each day as instructed.
• Do not change the dose without professional advice.
• Do not stop treatment abruptly unless specifically instructed by a healthcare professional.

Dose adjustments may be appropriate in certain patients, including those with hepatic or renal impairment.

When Not to Use

Paroxetine should generally not be used in patients with a known hypersensitivity to paroxetine or any component of the formulation.

It should not be used concurrently with monoamine oxidase inhibitors (MAOIs) because of the risk of serious interactions, including serotonin syndrome. Appropriate washout periods are required when switching between paroxetine and certain MAOIs.

Medical advice is particularly important for patients with:

• Bipolar disorder or a history of mania
• Seizure disorders
• Liver or kidney impairment
• Bleeding disorders
• Low sodium levels
• Glaucoma
• Significant cardiovascular conditions

Drug / Product Interactions

Paroxetine has clinically important interactions with several medicines and should be reviewed as part of the patient’s complete medication profile.

Important interaction categories include:

• Monoamine oxidase inhibitors (MAOIs)
• Other serotonergic medicines
• Certain antidepressants
• Tricyclic antidepressants
• Certain migraine medicines such as triptans
• Tramadol and other serotonergic analgesics
• Anticoagulants and antiplatelet medicines
• NSAIDs, which may increase bleeding risk
• Tamoxifen, because paroxetine can inhibit CYP2D6 and may reduce formation of active tamoxifen metabolites
• Certain medicines affecting cardiac rhythm

Patients should inform their healthcare professional about all prescription medicines, over-the-counter products, and supplements they use.

Safety Advice

Overdose

If an overdose is suspected, seek immediate medical attention or contact an appropriate poison-control or emergency medical service.

Missed Dose

Take the missed dose when remembered unless it is nearly time for the next scheduled dose. If the next dose is due soon, skip the missed dose and continue with the regular schedule. Do not double the next dose.

Pregnancy

Paroxetine should be used during pregnancy only after appropriate clinical assessment. Use during pregnancy, particularly later pregnancy, may be associated with specific neonatal risks, and treatment decisions should be made with a qualified healthcare professional.

Breastfeeding

Paroxetine passes into breast milk in small amounts. A healthcare professional should assess the benefits of treatment and potential risks to the breastfed infant.

Children

Paroxetine is not routinely indicated for all paediatric conditions. Use in children and adolescents should follow the approved product information and specialist healthcare guidance.

Elderly Patients

Older patients may be more susceptible to adverse effects such as hyponatremia, bleeding, and other treatment-related reactions. Appropriate monitoring may be required.

Renal Impairment

Patients with significant renal impairment may require dosage consideration or adjustment according to the approved product information.

Hepatic Impairment

Patients with hepatic impairment may require dosage adjustment because paroxetine is extensively metabolized in the liver.

General Instructions

• Take paroxetine according to the prescribed schedule.
• Swallow the tablet with sufficient water unless otherwise directed.
• Do not stop treatment abruptly.
• Do not change the dose without professional advice.
• Inform the healthcare professional about all other medicines being taken.
• Monitor for significant changes in mood, behavior, or unusual symptoms.
• Keep the medicine in its original packaging where appropriate.
• Do not share prescription medicines with other people.

Special Dietary / Lifestyle Tips

No specific dietary restriction is generally required unless advised by a healthcare professional.

Alcohol may increase drowsiness or other central nervous system effects in some patients. Patients should exercise caution with alcohol and discuss its use with their healthcare professional.

Comparison with Other Treatments

Paroxetine belongs to the SSRI class of antidepressants. Other antidepressants may belong to different classes and can have different mechanisms, interaction profiles, adverse effects, and approved indications.

The choice of antidepressant depends on the condition being treated, previous treatment response, concurrent medicines, tolerability, medical history, and other clinical considerations.

Precautions & Warnings

• Do not discontinue paroxetine abruptly because withdrawal symptoms may occur.
• Monitor for significant changes in mood or behavior, particularly during treatment initiation or dose changes.
• Patients with bipolar disorder should be assessed for the possibility of manic episodes.
• Use caution in patients with seizure disorders.
• Use caution when combined with medicines that increase bleeding risk.
• Serotonergic medicines may increase the risk of serotonin syndrome.
• Paroxetine may interact with tamoxifen through CYP2D6 inhibition.
