Derest 0.5mg/10mg Tablet

Derest 0.5mg/10mg Tablet combines Flupenthixol, a thioxanthene derivative with dopamine receptor-blocking activity, and Melitracen, a tricyclic antidepressant that acts on monoamine neurotransmission. The combination is widely used in clinical practice for patients experiencing depressive symptoms accompanied by anxiety, irritability, psychosomatic complaints, and functional distress.

Flupenthixol at low doses acts differently from its higher-dose antipsychotic use. In small therapeutic doses, it produces anxiolytic, activating, and mood-improving effects by modulating dopamine transmission in central nervous system pathways. This helps reduce emotional tension, nervousness, agitation, and mental restlessness without producing strong sedation in most patients.

Melitracen is a tricyclic antidepressant that inhibits the reuptake of noradrenaline and serotonin, increasing their concentration in synaptic clefts within the brain. This improves mood regulation, emotional stability, and cognitive response over time. Compared with some older tricyclic antidepressants, Melitracen is often used at low doses in combination therapy to improve tolerability.

The rationale of combining these two medicines is to achieve both rapid symptom relief for anxiety-related distress and gradual antidepressant benefit, particularly in patients where depression presents with autonomic symptoms such as palpitations, gastrointestinal discomfort, fatigue, poor sleep, and functional bodily complaints.

This combination is commonly prescribed in mild to moderate depression, mixed anxiety-depression states, psychosomatic disorders, functional gastrointestinal complaints associated with emotional stress, and stress-related autonomic symptoms.

Because the medicine acts on central neurotransmitter systems, it should only be used under regular medical supervision and not discontinued abruptly without advice.

The uses of Derest 0.5mg/10mg Tablet are as follows:

Anxiety Associated with Depression

Helps reduce nervousness, restlessness, and low mood occurring together.

Mild to Moderate Depressive Disorders

Used where depressive symptoms do not require heavy sedative antidepressants.

Psychosomatic Disorders

Useful in stress-related bodily symptoms such as palpitations, gastrointestinal discomfort, and fatigue.

Mixed Anxiety-Depression States

Helps control emotional instability and tension.

Stress-Related Functional Symptoms

Used in selected patients with emotional stress affecting daily functioning.

Here are the benefits of Derest 0.5mg/10mg Tablet:

• Dual action on mood and anxiety: One component improves mood while the other reduces tension.

• Supports emotional stability: Helps improve mental calmness and reduce irritability.

• Useful in psychosomatic symptoms: May improve physical symptoms associated with stress.

• Improves daily functioning: Helps reduce mental fatigue and emotional distress.

• Low-dose balanced therapy: Designed for mild to moderate psychiatric symptoms.

• Supports early symptom relief: Flupenthixol may provide relatively early anxiolytic benefit.

Like all medicines, Derest 0.5mg/10mg Tablet may cause side effects in some individuals, especially during the first few days of treatment.

Common Side Effects

• Dry Mouth: Frequently reported because of tricyclic antidepressant action.

• Dizziness: May occur during early treatment or dose adjustment.

• Mild Drowsiness: Some individuals may feel sleepy, particularly initially.

• Constipation: Common due to anticholinergic effect of Melitracen.

• Headache: Mild headache may occur during early use.

Uncommon Side Effects

• Blurred Vision: Temporary visual discomfort may occur in sensitive individuals.

• Palpitations: Mild increase in awareness of heartbeat may occur.

• Sleep Disturbance: Occasionally vivid dreams or altered sleep pattern may occur.

Serious Side Effects (Require Immediate Medical Attention)

• Severe Restlessness or Muscle Stiffness: May indicate extrapyramidal reaction.

• Marked Mood Changes: Severe agitation or unusual behavioural changes need medical review.

• Irregular Heartbeat: Requires urgent medical attention.

• Severe Allergic Reaction: Swelling, rash, or breathing difficulty requires emergency care.

Always consult your doctor if side effects persist or worsen.

To ensure safe and effective use:

• Take exactly as prescribed.

• Usually taken once or twice daily depending on doctor’s advice.

• Swallow tablet whole with water.

• Can be taken with or without food.

• Avoid self-adjusting dose.

• Do not stop abruptly without medical advice.

Derest 0.5mg/10mg Tablet works through two complementary effects on central neurotransmitters.

Flupenthixol blocks dopamine receptors in selected brain pathways. At low doses, this helps reduce anxiety, emotional tension, and mental restlessness while improving mood balance.

Melitracen inhibits reuptake of noradrenaline and serotonin, increasing their concentration in the brain. This improves mood, emotional resilience, and antidepressant response over time.

Together, they help reduce both psychological and psychosomatic symptoms associated with anxiety and depression.

• Take at the same time daily.

• Avoid sudden stopping.

• Inform your doctor about mood changes.

• Follow psychiatric review regularly.

• Avoid alcohol during treatment.

• Store below 25°C

• Keep away from moisture

• Keep in original packaging

• Keep out of reach of children

Flupenthixol + Melitracen may be taken with or without food. However:

• Avoid excessive caffeine intake: High amounts of tea, coffee, energy drinks, or caffeinated beverages may increase nervousness, restlessness, or palpitations in sensitive individuals.

• Avoid alcohol: Alcohol may increase drowsiness, impair alertness, and enhance the sedative effects of the medicine.

• Maintain regular meal timing: Taking the medicine at a consistent time with regular meals may help improve gastric tolerance and reduce nausea in sensitive patients.

• Avoid sudden excessive stimulant intake: Large amounts of stimulants may interfere with emotional calmness during treatment.

Derest 0.5mg/10mg Tablet may interact with:

• Other Antidepressants: Concurrent use may increase central nervous system effects and raise the risk of excessive serotonergic or anticholinergic activity.

• Antipsychotic Medicines: Combined use may increase the risk of extrapyramidal symptoms, sedation, or cardiac effects.

• Sedatives and Tranquillisers: May increase drowsiness and impair alertness when taken together.

• Antihypertensives: Blood pressure-lowering effects may become more pronounced in some individuals.

• Antiarrhythmic Medicines: Certain antiarrhythmics may increase the risk of cardiac conduction abnormalities.

• Anticholinergic Medicines: Combined use may worsen dry mouth, constipation, blurred vision, or urinary difficulty.

• MAO Inhibitors: Should not be used together because serious central nervous system interactions may occur.

Derest 0.5mg/10mg Tablet should be used carefully in:

• Bipolar Disorder: Antidepressant components may trigger mood elevation or manic symptoms in susceptible individuals.

• Epilepsy: Seizure threshold may be lowered in predisposed patients, requiring careful supervision.

• Glaucoma: Anticholinergic effects may increase intraocular pressure in susceptible individuals.

• Cardiac Arrhythmia: Cardiac conduction disturbances may worsen in patients with existing rhythm disorders.

• Prostate Enlargement: Anticholinergic effects may increase difficulty in urination in susceptible individuals.

• Liver Impairment: Reduced hepatic metabolism may increase medicine exposure and require dose adjustment.

• Severe Depression with Suicidal Risk: Close psychiatric monitoring is essential, especially during the early phase of treatment.

The dose depends on clinical condition and psychiatric assessment. It is usually taken once or twice daily exactly as prescribed by your doctor.

If you miss a dose, take it when remembered unless the next dose is due soon. Do not double the dose.
