Nassa 15mg Tablets – Mirtazapine Antidepressant (nassa)
Description
Nassa 15mg Tablets — Mirtazapine Antidepressant (Rx)
Nassa 15mg Tablets contain Mirtazapine, a NaSSA (Noradrenergic and Specific Serotonergic Antidepressant) — a class distinct from SSRIs. Mirtazapine works by blocking presynaptic α2-adrenergic receptors, increasing the release of both norepinephrine and serotonin indirectly. It also blocks 5-HT2 and 5-HT3 receptors, which reduces anxiety and improves sleep quality without the sexual side effects associated with SSRIs.
Nassa 15mg is prescribed for major depressive disorder (MDD), particularly when depression is accompanied by sleep disturbance, poor appetite, and significant anxiety. At 15mg, the antihistamine (H1 blocking) effect is prominent, making it especially sedating and helpful for patients who struggle with insomnia. It also stimulates appetite, beneficial for patients with depression-related weight loss.
Clinical profile: Unlike SSRIs, Mirtazapine does not cause sexual dysfunction. It acts quickly on sleep (often within the first week). Patients should be aware of significant weight gain and increased appetite. Do not stop abruptly — gradual tapering is required. Prescription-only medicine.

FAQs
Is Mirtazapine (Nassa) an SSRI?
No. Mirtazapine is a NaSSA — it works by blocking α2-adrenergic receptors to increase norepinephrine and serotonin release, not by inhibiting serotonin reuptake. This gives it a different side-effect profile from SSRIs.
Why is the 15mg dose more sedating than 30mg?
At 15mg, Mirtazapine's antihistamine (H1) effect dominates over noradrenergic activity. At higher doses (30–45mg), increased noradrenergic stimulation partially counteracts the sedation.
Can I stop Nassa 15mg suddenly?
No. Abrupt discontinuation can cause withdrawal symptoms. Always taper gradually under your doctor's supervision.
Is a prescription required for Nassa 15mg?
Yes — prescription-only medicine. Send your valid Rx to sales@derma.pk or WhatsApp 0320-5999650.
