Indications & Clinical Uses

  • Mirtazapine is a tetracyclic antidepressant used primarily in the management of depressive disorders.
  • Major depressive disorder: alleviates depressive symptoms and improves overall mood.
  • Depression with insomnia: may enhance sleep quality while treating depressive symptoms.
  • Depression with anxiety: can reduce anxiety components associated with depressive episodes.

How It Works

  • Mirtazapine acts as an antagonist at central presynaptic α2‑adrenergic receptors, which increases norepinephrine release, and blocks serotonergic 5‑HT2 and 5‑HT3 receptors while stimulating 5‑HT1A receptors. This combined activity raises synaptic concentrations of norepinephrine and serotonin, contributing to its antidepressant effect.

Side Effects

Mirtazapine may cause a range of adverse reactions, from mild to serious.

Common Side Effects

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

Serious or Rare Side Effects

  • Agranulocytosis or severe neutropenia
  • Seizures
  • Hepatic dysfunction (jaundice, elevated enzymes)
  • Hyponatremia
  • Suicidal thoughts or worsening depression
  • Severe allergic reactions (rash, angioedema)

Precautions & Warnings

  • Before initiating therapy, consider the following precautions.
  • Pregnancy: safety not established; use only if benefits outweigh risks.
  • Elderly patients: increased sensitivity to sedation and weight gain.
  • Liver impairment: dose adjustment may be required.
  • Concurrent CNS depressants: may enhance sedative effects.
  • Monitor for mood worsening or emergent suicidal ideation.
  • Store at ambient temperature: keep in original container, protect from moisture and light.

Avoid Interactions

Mirtazapine can interact with several drug classes; monitoring is essential.

Major Interactions (Avoid)

  • MAO inhibitors: risk of hypertensive crisis.
  • CNS depressants (e.g., benzodiazepines, alcohol): additive sedation.
  • Strong CYP3A4 inhibitors (e.g., ketoconazole): increased mirtazapine plasma levels.

Moderate Interactions (Monitor Closely)

  • Anticholinergic agents: may increase anticholinergic burden.
  • Diuretics: potential electrolyte disturbances.
  • Lithium: monitor lithium serum concentrations.

Frequently Asked Questions

Mirtazapine Eg contains the antidepressant mirtazapine and is prescribed for the treatment of major depressive disorder in adult patients. It helps to relieve depressive symptoms, improve mood, and may also aid sleep and appetite when these are affected by depression.

Mirtazapine works by blocking presynaptic α2‑adrenergic receptors, which increases norepinephrine release, and by antagonising 5‑HT2 and 5‑HT3 serotonin receptors while stimulating 5‑HT1A receptors. This dual action raises levels of norepinephrine and serotonin in the brain, contributing to its antidepressant effect.

The dosage of Mirtazapine Eg is determined individually by a qualified prescriber based on the patient’s clinical condition, response, and tolerability. Only a healthcare professional can set the appropriate dose and any titration schedule.

Safety of mirtazapine in pregnancy and lactation has not been definitively established. It should be used only if the potential benefit to the mother outweighs any possible risk to the fetus or infant, and the decision should be made in consultation with a healthcare provider.

To 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.

Mirtazapine differs from selective serotonin reuptake inhibitors (SSRIs) by its dual noradrenergic and serotonergic activity and its strong antihistaminic effect, which often leads to sedation and weight gain. SSRIs typically have less sedation but may cause gastrointestinal upset; the choice depends on patient‑specific factors and side‑effect profiles.

Mirtazapine Eg should be stored at ambient temperature, preferably below 25 °C, in its original packaging to protect it from moisture and light. Keep the product out of reach of children and avoid storing it in humid or excessively hot environments.

Mirtazapine Eg is taken orally, usually once daily in the evening because of its sedative properties. It can be swallowed whole with or without food; however, taking it with a light snack may reduce gastrointestinal discomfort for some patients.

Serious risks include agranulocytosis or severe neutropenia, which can lead to infection, seizures, hepatic dysfunction, hyponatremia, and the emergence or worsening of suicidal thoughts. Patients should be monitored closely for signs of infection, liver problems, electrolyte imbalance, or changes in mood.

Mirtazapine Eg should be avoided in patients with known hypersensitivity to mirtazapine or any of its excipients, those currently taking monoamine oxidase inhibitors (MAOIs), and individuals with severe hepatic impairment unless a specialist advises otherwise. Caution is also advised for patients with a history of bipolar disorder or uncontrolled seizures.
