Indications & Clinical Uses

Mirtazapine acts on the central noradrenergic and serotonergic pathways to treat depressive disorders.

  • Major depressive disorder: reduces depressive symptoms and improves functional outcomes in adults.

How It Works

  • Mirtazapine antagonizes central presynaptic α2‑adrenergic receptors, increasing norepinephrine release, and blocks postsynaptic 5‑HT2, 5‑HT3 and H1 receptors, which enhances serotonergic transmission while reducing histamine‑mediated effects, leading to its antidepressant and anxiolytic actions.

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
  • Orthostatic hypotension

Serious or Rare Side Effects

  • Agranulocytosis or severe neutropenia
  • Seizures
  • Severe hypersensitivity reactions (e.g., Stevens‑Johnson syndrome)
  • Suicidal thoughts or behavior, especially early in treatment
  • Hepatic dysfunction
  • Leukopenia

Precautions & Warnings

Before initiating therapy, clinicians should evaluate patient‑specific factors and monitor for potential complications.

  • Psychiatric assessment: monitor for worsening depression or emergent suicidal ideation
  • Hepatic function: use with caution in patients with severe liver impairment
  • Cardiovascular status: observe blood pressure in hypertensive individuals
  • Discontinuation: avoid abrupt cessation; taper under medical supervision
  • Pregnancy and lactation: prescribe only if benefits outweigh potential risks
  • Store at ambient temperature: keep in the original container, protect from moisture and light

Avoid Interactions

Mirtazapine can interact with several drug classes, requiring careful management.

Major Interactions (Avoid)

  • Monoamine oxidase inhibitors (MAOIs): risk of hypertensive crisis
  • Strong CYP2D6 inhibitors (e.g., fluoxetine, paroxetine): may increase mirtazapine plasma levels
  • Central nervous system depressants (e.g., alcohol, benzodiazepines): enhanced sedation and respiratory depression

Moderate Interactions (Monitor Closely)

  • Anticholinergic agents: additive dry‑mouth effects
  • Other serotonergic drugs (e.g., tramadol, triptans): potential serotonin syndrome
  • Warfarin: possible increase in INR, requiring coagulation monitoring

Frequently Asked Questions

Mirtazapina Sandoz contains the active ingredient mirtazapine and is used to treat major depressive disorder in adult patients. It helps alleviate depressive symptoms such as low mood, loss of interest, sleep disturbances, and appetite changes, supporting overall functional recovery.

Mirtazapine works by blocking presynaptic α2‑adrenergic receptors, which increases the release of norepinephrine, and by antagonising postsynaptic 5‑HT2, 5‑HT3 and H1 receptors. This combined action enhances serotonergic and noradrenergic neurotransmission while reducing histamine‑mediated sedation, producing antidepressant and anxiolytic effects.

The specific dose of Mirtazapina Sandoz is determined by the prescribing clinician based on the individual’s clinical condition, response, and tolerability. Typical initiation may start at 15 mg once daily, with possible adjustments, but the exact regimen should always follow the prescriber’s instructions.

Safety data for mirtazapine in pregnancy and lactation are limited. It should only be used when the potential benefit to the mother outweighs any possible risk to the fetus or infant. Healthcare providers should discuss individual risks and consider alternative therapies when appropriate.

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 (including any cold‑chain requirements) and necessary import documentation.

Mirtazapine belongs to the NaSSA class, differing from selective serotonin reuptake inhibitors (SSRIs) that primarily increase serotonin levels. Its combined noradrenergic and serotonergic activity often results in stronger sedative and appetite‑stimulating effects, making it useful for patients with insomnia or weight loss, whereas SSRIs tend to have a more activating profile.

Mirtazapina Sandoz should be stored at ambient temperature, below 25 °C, in the original packaging to protect it from moisture and light. Keep the product out of reach of children and avoid storing it in bathrooms or other humid environments.

The medication is supplied as oral tablets and is taken by mouth, usually once daily in the evening due to its sedative properties. Patients should swallow the tablet whole with water and follow the dosing schedule prescribed by their healthcare professional.

Serious adverse events include the potential for suicidal thoughts or behaviors, especially early in treatment, agranulocytosis or severe neutropenia, severe hypersensitivity reactions such as Stevens‑Johnson syndrome, seizures, and significant hepatic dysfunction. Any of these symptoms require immediate medical attention.

Mirtazapina Sandoz should be avoided in patients with known hypersensitivity to mirtazapine or any of its excipients, those currently taking monoamine oxidase inhibitors, individuals with severe hepatic impairment, and patients with a history of agranulocytosis. Clinicians must evaluate each patient’s medical history before prescribing.
