Indications & Clinical Uses

  • Mianserin is a tetracyclic antidepressant that acts on depressive disorders and related conditions.
  • Major depressive disorder: alleviates depressive symptoms and improves mood in adults.
  • Depressive episodes in bipolar disorder: helps control depressive phases when used under specialist supervision.
  • Treatment‑resistant depression: may be considered when first‑line agents have been ineffective.

How It Works

  • Mianserin blocks central presynaptic α2‑adrenergic receptors, increasing norepinephrine release, and antagonizes histamine H1, serotonin 5‑HT2 and 5‑HT3 receptors. This combined action enhances noradrenergic and serotonergic neurotransmission, contributing to its antidepressant effect.

Side Effects

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

Common Side Effects

  • Sedation or drowsiness
  • Weight gain or increased appetite
  • Dry mouth
  • Constipation
  • Dizziness or light‑headedness
  • Orthostatic hypotension

Serious or Rare Side Effects

  • Agranulocytosis or severe neutropenia
  • Seizures
  • Cardiac arrhythmias or QT prolongation
  • Severe hypotension
  • Suicidal thoughts or behavior
  • Hepatotoxicity

Precautions & Warnings

  • Before initiating therapy, clinicians should evaluate several safety considerations.
  • Monitor blood pressure: watch for orthostatic changes.
  • Assess suicidal risk: especially during early treatment.
  • Use caution in the elderly: increased sensitivity to sedation and falls.
  • Avoid abrupt discontinuation: taper to reduce withdrawal symptoms.
  • Review hepatic function: adjust if liver impairment is present.
  • Store at room temperature: keep in the original container, protect from moisture and direct sunlight.

Avoid Interactions

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

Major Interactions (Avoid)

  • Monoamine oxidase inhibitors (MAOIs): risk of hypertensive crisis.
  • Selective serotonin reuptake inhibitors (SSRIs) or other serotonergic agents: potential serotonin syndrome.
  • Other antidepressants (TCAs, SNRIs): additive CNS depression.
  • CNS depressants (benzodiazepines, barbiturates): enhanced sedation.
  • QT‑prolonging drugs: increased cardiac risk.

Moderate Interactions (Monitor Closely)

  • CYP2D6 inhibitors (e.g., fluoxetine, paroxetine): may raise mianserin levels.
  • Antihypertensives: additive hypotensive effect.
  • Anticholinergic medications: heightened anticholinergic burden.
  • Alcohol: increased sedation and dizziness.
  • NSAIDs: potential for gastrointestinal bleeding when combined with anticoagulants.

Frequently Asked Questions

Mianserine Teva contains the active ingredient mianserin, a tetracyclic antidepressant indicated for the treatment of major depressive disorder in adult patients. It may also be used under specialist supervision for depressive episodes in bipolar disorder or for patients whose depression has not responded to first‑line therapies.

Mianserin acts by blocking presynaptic α2‑adrenergic receptors, which increases the release of norepinephrine. It also antagonizes histamine H1 and serotonin 5‑HT2/5‑HT3 receptors, leading to enhanced noradrenergic and serotonergic neurotransmission that helps alleviate depressive symptoms.

The appropriate dose of Mianserine Teva is determined by the prescribing clinician based on the individual patient's condition, response, and tolerability. Dosage adjustments are made according to clinical guidelines and patient-specific factors.

Safety data for mianserin in pregnancy and lactation are limited. The drug should only be used if the potential benefit justifies any potential risk to the fetus or infant, and the decision must be made by a qualified healthcare professional.

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.

Mianserine Teva belongs to the tetracyclic class, differing from SSRIs and SNRIs in its receptor profile. It tends to cause more sedation and weight gain but has a lower risk of sexual dysfunction. Its unique mechanism may be advantageous for patients who do not respond to or cannot tolerate other antidepressant classes.

Mianserine Teva should be stored at room temperature, below 25 °C, in its original packaging. Keep the product away from moisture and direct sunlight to maintain stability and potency.

Mianserine Teva is taken orally, usually with or without food, as directed by the prescribing physician. Swallow the tablet whole with a glass of water and follow the dosing schedule provided by the healthcare professional.

Serious risks include agranulocytosis, seizures, severe hypotension, cardiac arrhythmias (including QT prolongation), and the emergence or worsening of suicidal thoughts. Patients should be monitored closely for these events, especially during treatment initiation or dose changes.

Mianserine Teva is contraindicated in patients taking monoamine oxidase inhibitors, those with known hypersensitivity to mianserin, and individuals with severe hepatic impairment. Caution is also advised for patients with a history of cardiac arrhythmias, uncontrolled hypertension, or active suicidal ideation.
