Paroxetine, an SSRI, modulates serotonergic pathways and is indicated for several psychiatric disorders. - Major depressive disorder: reduces depressive symptoms and improves mood. - Generalized anxiety disorder: alleviates excessive worry and tension. - Social anxiety disorder: decreases fear of social situations and performance. - Panic disorder: lessens frequency and intensity of panic attacks. - Obsessive‑compulsive disorder: diminishes intrusive thoughts and compulsive behaviors. - Post‑traumatic stress disorder: helps control re‑experiencing and hyperarousal symptoms.

Paroxetine may cause a range of adverse reactions, varying from mild to severe.

Common Side Effects: - Nausea - Headache - Dry mouth - Insomnia

Serious or Rare Side Effects: - Serotonin syndrome - Suicidal thoughts or behaviors - Severe hyponatremia - QT interval prolongation - Severe allergic reactions (e.g., angioedema) - Mania or hypomania

When prescribing Paroxetine, clinicians should observe several precautionary measures to ensure patient safety. - Assess for suicidal ideation: monitor patients, especially during early treatment. - Avoid concomitant MAO‑inhibitors: discontinue MAOIs at least 14 days before starting. - Use caution in hepatic impairment: dose adjustments may be required. - Do not discontinue abruptly: taper the dose to reduce withdrawal symptoms. - Pregnancy and lactation: prescribe only if benefits outweigh potential risks. - Store at below 25°C: keep in original packaging, protect from moisture and light.

Paroxetine interacts with several medicines; awareness of the interaction level guides clinical decisions.

Major Interactions (Avoid): - MAO inhibitors (e.g., phenelzine): risk of serotonin syndrome. - Pimozide: can cause cardiac arrhythmias. - Thioridazine: increased risk of QT prolongation. - Linezolid: heightened serotonergic activity leading to syndrome.

Moderate Interactions (Monitor Closely): - NSAIDs (e.g., ibuprofen): may increase bleeding risk. - Anticoagulants (e.g., warfarin): monitor INR closely. - CYP2D6 inhibitors (e.g., fluoxetine): may raise paroxetine plasma levels. - Alcohol: can enhance CNS depression.
