Forms and strengths

Trazodone is available as capsules (50 mg, 100 mg), tablets (150 mg) and an oral liquid (50 mg/5 mL). Active ingredient: trazodone. ATC code: N06AX05.

Indications and uses

Molipaxin is licensed in the UK for depressive illness, with or without anxiety. Short-term use at lower doses at night for insomnia associated with depression is a common clinical practice outside the licence (off-label).

It is not approved for children, and caution is required in people with cardiac disease or active suicidal thoughts.

Dosing and titration

• Starting dose: begin at the lowest effective dose for the problem being treated.
• Up-titration steps: the dose is increased gradually, as directed by the prescriber, while tolerability is monitored.
• Monitoring points: watch for sedation, orthostatic hypotension and drug interactions.
• Stopping treatment: reduce the dose gradually under prescriber supervision to avoid withdrawal symptoms.

Missed doses should be taken as soon as remembered unless the next dose is near; do not double up.

An overdose can be harmful, so seek medical help promptly (NHS 111, or 999 in an emergency). Risks including extreme drowsiness, hypotension, cardiac arrhythmia and serotonin syndrome.

Pharmacology and mechanism in plain language

Molipaxin contains trazodone, an antidepressant with several actions: it inhibits serotonin reuptake while blocking certain serotonin receptors, and it also has antihistaminic and alpha‑adrenergic blocking effects that contribute to sedation.

Antidepressant effects commonly take between two and six weeks to become fully apparent, while sedative effects are often seen right away at initial doses.

Practical implications include:

• Sleep benefit: Typically faster onset than mood benefit.
• Daytime sedation and dizziness: Result from antihistamine and alpha‑blockade.
• Orthostatic hypotension: Clinically relevant, especially in older or frail patients.

Safety profile — common and serious adverse effects

Absolute contraindications include known hypersensitivity to trazodone, concurrent use of MAO inhibitors or within 14 days, and the acute recovery phase following myocardial infarction.

Seek immediate medical care for chest pain, fainting, prolonged painful erections or signs of serotonin syndrome such as high fever, agitation and loss of coordination.

Do not drive or operate machinery until you know how the medicine affects you, because of drowsiness and dizziness.

Drug interactions and management

Important interactions

• MAO inhibitors: Contraindicated during use and for 14 days after stopping an MAOI.
• Other serotonergic drugs: SSRIs, SNRIs and triptans raise serotonin syndrome risk when combined.
• CYP3A4 inhibitors/inducers: Strong CYP3A4 inhibitors may increase trazodone levels; inducers may reduce efficacy.
• CNS depressants: Alcohol, benzodiazepines and opioids produce additive sedation and respiratory depression risk.

Special populations: elderly, pregnancy, paediatrics

• Elderly: Start low and titrate slowly due to increased risk of sedation, orthostatic hypotension and falls; monitor blood pressure and balance.
• Pregnancy and breastfeeding: Data are limited; weigh maternal benefit versus potential neonatal risks and involve obstetrics in decision making.
• Paediatrics: Not approved for children; safety and efficacy are unestablished.
• Hepatic/renal impairment: Use with caution and consider dose reduction with close monitoring because metabolism and clearance can be altered.

Comparators and therapeutic positioning

When molipaxin is chosen over alternatives

Positioning bullets for patients:

• Ideal: Depressed patients with significant insomnia or those needing adjunctive sleep support.
• Less ideal: Patients where anticholinergic burden, pronounced cardiac risk or severe orthostatic hypotension is a concern.
• Common strategy: Low‑dose trazodone added to an SSRI for residual insomnia under close supervision.

Key patient messages

• Dose and timing: for insomnia a lower dose is taken at bedtime; for depression follow the divided or bedtime dosing directed by your prescriber.
• Daytime drowsiness and dizziness on standing can occur; avoid alcohol and do not drive or operate heavy machinery until you know how the medicine affects you.
• Timeline: sleep benefit may be noticed sooner, while mood improvement can take one to six weeks.
• Do not stop abruptly without consulting your prescriber; the dose should be reduced gradually.
• Seek urgent help for priapism, chest pain, fainting, severe dizziness and any new or worsening suicidal thoughts.

Monitoring, follow‑up and red flags

Check‑ins are usually arranged at 1–2 weeks and again at 4–6 weeks to assess mood response and adverse events.

For higher‑risk patients, record baseline blood pressure and pulse, and perform orthostatic checks; consider ECG if there is a significant cardiac history or if combined with QT‑prolonging drugs.

Escalate promptly for signs of serotonin syndrome such as agitation, hyperreflexia and fever, for priapism (urgent urology review) and for new or worsening suicidal ideation which requires immediate psychiatric assessment.

For long‑term users review the ongoing need every three to six months and encourage deprescribing conversations when clinically appropriate.

Frequently asked questions

• Is Molipaxin the same as trazodone/Desyrel? Yes. Molipaxin is a trazodone product.
• How long until I sleep better? Many patients notice sleep improvement within nights to a week, but mood benefits can take 1–6 weeks.
• Can I mix with alcohol or other antidepressants? Avoid alcohol and be cautious with other serotonergic antidepressants due to serotonin syndrome risk; check with the prescriber or pharmacist.
• Is it available on the NHS? Trazodone is prescription‑only and and may be prescribed on the NHS.
