Levomepromazine Orion (Levomepromazine)

Levomepromazine works by blocking dopamine D2 receptors, which reduces dopaminergic activity linked to psychosis. It also antagonizes histamine H1, muscarinic, and alpha‑adrenergic receptors, providing antiemetic, antihistaminic, and sedative effects that contribute to its therapeutic actions.

The appropriate dose of Levomepromazine Orion is determined individually by the prescribing clinician based on the patient’s condition, response, and tolerability. Dosage may be adjusted over time, and patients should follow the specific instructions provided by their healthcare professional.

Safety data for Levomepromazine during pregnancy and lactation are limited. It should only be used when 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 qualified healthcare provider.

Levomepromazine differs from many typical antipsychotics such as haloperidol by having stronger antihistaminic, anticholinergic, and antiemetic properties, which can be advantageous for patients with nausea or requiring sedation. However, it may also produce more pronounced sedation and orthostatic hypotension compared with some newer agents.

Levomepromazine Orion should be stored at room temperature, below 25 °C, in its original packaging to protect it from moisture and light. Keep the container tightly closed and out of reach of children.

Levomepromazine Orion is taken orally. The tablet should be swallowed whole with water and not chewed or crushed, unless otherwise directed by a healthcare professional.

The most serious adverse reactions to watch for include neuroleptic malignant syndrome, tardive dyskinesia, severe hypotension or cardiac arrhythmias, agranulocytosis, and seizures. Patients should be monitored closely for any signs of these conditions and seek immediate medical attention if they occur.

Levomepromazine Orion is contraindicated in individuals with known hypersensitivity to levomepromazine or other phenothiazines, in patients with severe central nervous system depression, and in those with uncontrolled cardiovascular disease where significant hypotension could be hazardous.
