The main differences between sertraline and flupentixol-melitracen capsules lie in drug class, indications, mechanisms of action, side effect profiles, and medication precautions, requiring appropriate selection based on the specific condition. If emotional disturbances, obsessive symptoms, or similar issues occur, prompt medical evaluation for proper medication use is recommended.

1. Different drug classes: Sertraline is a selective serotonin reuptake inhibitor (SSRI) and a single-component antidepressant; flupentixol-melitracen capsule is a combination formulation containing the antipsychotic flupentixol and the antidepressant melitracen.

2. Different indications: Sertraline is primarily used to treat depression, obsessive-compulsive disorder (OCD), panic disorder, and related conditions; flupentixol-melitracen is more suitable for mild to moderate depression, anxiety disorders, neurasthenia, and psychogenic depression, among other neuroses.

3. Different mechanisms of action: Sertraline increases brain neurotransmitter concentrations by inhibiting serotonin reuptake; flupentixol-melitracen exerts its effects by regulating the balance of multiple neurotransmitters, including dopamine and serotonin.

4. Different side effect profiles: Common side effects of sertraline include gastrointestinal discomfort, dizziness, and insomnia; flupentixol-melitracen may cause dry mouth, constipation, tremors, and long-term use requires monitoring for extrapyramidal symptoms.

5. Different medication precautions: Sertraline dosage should be gradually increased, and discontinued slowly to avoid withdrawal reactions; flupentixol-melitracen should not be used concomitantly with monoamine oxidase inhibitors (MAOIs), and dose adjustments are necessary for patients with impaired liver or kidney function.

Medication must be strictly taken as prescribed—do not switch medications or adjust doses independently. Avoid alcohol during treatment, maintain regular sleep patterns, record bodily responses for physician review and regimen adjustments, and combine with psychological interventions to enhance therapeutic outcomes.

How long should sertraline be taken at a frequency of one tablet every two days before switching to one tablet every three days?

If the condition remains stable after taking one tablet every two days (such as normal mood, sleep, and social functioning), and this stability has been maintained for 2–3 consecutive months without significant physical discomfort (e.g., dizziness, nausea), the doctor may suggest attempting to reduce the dosage further to one tablet every three days. During this phase, it is essential to closely monitor for any fluctuations in symptoms to ensure that there is no relapse following the dose reduction.

If leg weakness is accompanied by palpitations, insomnia, or worsening anxiety, prompt medical attention is recommended.

During treatment, take the medications regularly as prescribed to avoid missed doses, which may affect therapeutic efficacy. Maintain a light diet, reduce intake of spicy and greasy foods, and minimize gastrointestinal burden. If dizziness occurs, sit or lie down immediately.
