Mirzacan (Mirtazapine 15 / 30 mg) is a tetracyclic antidepressant (NaSSA) for major depression, particularly when insomnia, anxiety, weight loss, or anorexia are dominant symptoms. Strongly sedating at low doses, less sedating at higher doses (counterintuitive — see below).

What Mirzacan is and how it works
Mirzacan is a 15 / 30 mg mirtazapine tablet supplied by Cadila. Mirtazapine is structurally and mechanistically distinct from SSRIs/SNRIs/TCAs. It is a noradrenergic and specific serotonergic antidepressant (NaSSA): it blocks central α2-adrenergic autoreceptors (raising NA and 5-HT release indirectly), 5-HT2A and 5-HT2C receptors (anxiolytic, sleep-promoting, no sexual dysfunction), and H1 histamine receptors (sedation and appetite stimulation).
At 7.5–15 mg, mirtazapine is most sedating. At 30 mg+, the noradrenergic component (which is more linearly dose-related than the H1 antihistaminergic component) starts to offset the H1 sedation. Many patients describe 30 mg as “feeling more energised” than 15 mg. If a patient wants more sleep, lower the dose — not raise it.
Indikace a dávkování
| Indikace | Počáteční dávka | Cílová dávka | Maximální dávka |
|---|---|---|---|
| Hlavní deprese | 15 mg HS | 30 mg HS | 45 mg |
| Depression with insomnia | 7.5–15 mg HS | 15 mg HS (often sufficient) | 30 mg |
| Depression with weight loss / anorexia | 15 mg HS | 30–45 mg HS | 45 mg |
| SSRI augmentation | 7.5–15 mg HS added to SSRI | 15 mg HS | 30 mg |
| Older adults | 7.5 mg HS | 15 mg HS | 30 mg |
Důležité bezpečnostní aspekty
Mirtazapine is one of the heaviest-weight-gain antidepressants — typical 4–7 kg over 6 months. Useful in patients with depression-related weight loss; problematic in obese or metabolic-syndrome patients. Check fasting lipids and HbA1c at 6 months.
Reversible neutropenia and rare agranulocytosis described — incidence approximately 1 in 1000. Stop immediately and check FBC if fever, sore throat, mouth ulcers, or other signs of infection appear in the first 8 weeks. Routine FBC is not required.
Mirtazapine commonly worsens restless legs syndrome and periodic limb movements of sleep — relevant in patients with prior RLS or sleep complaints.

Časté nežádoucí účinky
- Sedation: universal at 15 mg; lessens at 30+ mg; bedtime dosing harnesses it as benefit.
- Weight gain and increased appetite: 4–7 kg typical at 6 months.
- Dry mouth: common, mild.
- Constipation: mild anticholinergic action.
- No sexual dysfunction: distinct advantage over SSRIs.
- Vivid dreams: some patients describe unusually intense dreams.
- Cholesterol / triglycerides: small mean rise.
Interakce léků
- MAOIs — 14-day washout each direction.
- Strong CYP3A4 inhibitors / inducers — moderate effect on mirtazapine levels.
- CNS depressants (alcohol, benzodiazepines, opioids, Z-drugs) — additive sedation.
- Other serotonergic drugs — serotonin syndrome described but uncommon (mirtazapine’s 5-HT2A antagonism is partly protective).
- Warfarin — small INR rise; monitor.
Těhotenství, kojení, pediatrie
Pregnancy: limited data; weigh against untreated maternal depression. Breastfeeding: passes into milk; sometimes used in postpartum depression where insomnia and weight loss are concerns. Paediatric: not first-line.

Často kladené dotazy
Why is Mirzacan more sedating at 15 mg than at 30 mg?
Mirtazapine has dose-dependent effects on different receptors. At 15 mg, the H1 antihistamine action dominates — strongly sedating. At 30 mg+, the noradrenergic action ramps up and offsets the sedation. This is the opposite of intuition and is the most-asked question about mirtazapine. If your sleep is too heavy, raise the dose; if you want more sleep, lower it.
Will Mirzacan make me gain weight?
Yes — typically 4–7 kg over 6 months. This is one of the most reliable side effects. In patients with depression-driven weight loss it’s a feature; in obese patients it’s a problem. Discuss this trade-off explicitly before starting.
Why is Mirzacan taken at bedtime?
The H1 antihistamine sedation peaks 2–3 hours after the dose. Bedtime dosing recruits the sedation as a sleep benefit instead of daytime drowsiness. Morning dosing produces unacceptable drowsiness in most patients.
How is Mirzacan different from an SSRI?
Different mechanism (α2 + 5-HT2A/2C + H1 blockade vs SERT inhibition) translates to: more sedation, more appetite, more weight gain, no sexual dysfunction, less GI upset, less anxiety surge. Useful when those SSRI side effects are problematic or when insomnia/weight loss are dominant symptoms.
Can Mirzacan be combined with an SSRI?
Yes — the so-called “California rocket fuel” (SSRI/SNRI + mirtazapine) is a recognised combination for severe or partial-response depression. Mirtazapine is added typically at 7.5–15 mg HS. Specialist supervision recommended.
How long until Mirzacan works?
Sleep and appetite often improve within 1–2 weeks; the mood effect builds over 4–6 weeks at 15–30 mg.
How do I stop Mirzacan?
Taper over 2–4 weeks. Withdrawal is generally milder than SSRI/SNRI withdrawal but rebound insomnia and dysphoria are described.
Will Mirzacan affect my driving?
Yes — the first 1–2 weeks of sedation can impair reaction time. Avoid driving until you know your tolerability. After that, most patients drive normally on stable doses.
Does Mirzacan help anxiety?
Yes — the 5-HT2A and 5-HT2C antagonism contributes a meaningful anxiolytic effect, often visible within the first 1–2 weeks. Useful when depression and anxiety co-exist.
Is Mirzacan addictive?
No — no euphoria, no compulsive use, no escalating tolerance. Physical dependence is mild and shorter than SSRI dependence.
