Indications & Clinical Uses

Mirtazapine acts within the central nervous system to alleviate depressive symptoms and is approved for use in major depressive disorder.

  • Major depressive disorder: reduces depressive mood, improves sleep and appetite in adults.
  • Depressive episodes in adults: alleviates core symptoms of sadness, loss of interest and low energy.
  • Depression with insomnia: helps restore sleep patterns while treating depressive signs.

How It Works

  • Mirtazapine antagonizes central presynaptic α2‑adrenergic receptors, thereby enhancing noradrenergic transmission, and blocks 5‑HT2 and 5‑HT3 serotonergic receptors as well as H1 histamine receptors. This combined receptor profile increases noradrenaline and serotonin release while producing sedative effects, contributing to its antidepressant activity.

Side Effects

Mirtazapine may cause a range of adverse reactions that vary in frequency and severity.

Common Side Effects

  • Sedation or drowsiness
  • Increased appetite and weight gain
  • Dry mouth
  • Constipation
  • Dizziness
  • Fatigue

Serious or Rare Side Effects

  • Agranulocytosis or severe neutropenia
  • Stevens‑Johnson syndrome or toxic epidermal necrolysis
  • Suicidal thoughts or behavior
  • Severe hypotension
  • Hepatic dysfunction
  • Seizures (rare)

Precautions & Warnings

Before initiating therapy with Mirtazapin Sandoz, several safety considerations should be reviewed.

  • Pregnancy: safety not established; use only if potential benefit justifies risk.
  • Breastfeeding: unknown excretion; consider alternative therapy.
  • Elderly patients: monitor for excessive sedation and fall risk.
  • Concomitant CNS depressants: may potentiate sedation and respiratory depression.
  • History of bipolar disorder: risk of mood elevation or rapid cycling.
  • Store at ambient temperature: keep in original container, protect from moisture and light.

Avoid Interactions

Mirtazapin Sandoz can interact with other medicines, requiring careful assessment of the interaction potential.

Major Interactions (Avoid)

  • MAO inhibitors: risk of serotonin syndrome and hypertensive crisis.
  • Strong CYP2D6 inhibitors (e.g., fluoxetine, paroxetine): may increase mirtazapine plasma levels.
  • CNS depressants (alcohol, benzodiazepines): additive sedation and respiratory depression.

Moderate Interactions (Monitor Closely)

  • CYP3A4 inducers (e.g., carbamazepine, phenytoin): may reduce therapeutic effect.
  • Anticholinergic agents: increased anticholinergic burden.
  • Warfarin: potential alteration of INR, requiring closer monitoring.

Frequently Asked Questions

Mirtazapin Sandoz contains the active ingredient mirtazapine and is used to treat major depressive disorder in adult patients. It helps improve mood, sleep, and appetite by influencing neurotransmitter activity in the brain.

Mirtazapine works by blocking presynaptic α2‑adrenergic receptors, which increases the release of norepinephrine and serotonin. It also antagonizes certain serotonin (5‑HT2, 5‑HT3) and histamine (H1) receptors, contributing to its antidepressant and sedative effects.

The appropriate dose of Mirtazapin Sandoz is determined by the prescribing clinician based on the individual patient's condition, response, and tolerability. Dosage adjustments are made according to clinical judgment and patient needs.

Safety of mirtazapine in pregnancy has not been fully established, and it is generally prescribed only when the potential benefit outweighs the risk. Its excretion in breast milk is unknown, so caution is advised and alternative treatments may be considered.

To place an order, submit an enquiry on the product page at gnhindia.com specifying the required quantity. GNH India works with hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details and any necessary import documentation.

Mirtazapin Sandoz belongs to the NaSSA class, which differs from SSRIs and SNRIs by its dual antagonism of α2‑adrenergic and specific serotonin receptors. This mechanism often results in pronounced sedative and appetite‑stimulating effects, making it useful for patients with insomnia or weight loss, whereas other antidepressants may lack these properties.

Mirtazapin Sandoz should be stored at ambient temperature, below 25 °C, in its original packaging. Protect the tablets from moisture, excessive heat and direct sunlight to maintain product stability.

Mirtazapin Sandoz is taken orally, usually once daily in the evening, as directed by the prescriber. The tablets should be swallowed whole with water and not crushed or chewed unless otherwise instructed.

Serious risks include the potential for agranulocytosis, severe neutropenia, Stevens‑Johnson syndrome, and increased suicidal thoughts, especially when initiating therapy or adjusting dose. Patients should be monitored for signs of infection, skin reactions, or worsening mood.

Mirtazapin Sandoz is contraindicated in patients who have taken a monoamine oxidase inhibitor within the past 14 days. Caution is also advised for individuals with known hypersensitivity to mirtazapine or any of its excipients, and for those with severe hepatic impairment.
