Haflur 20 Tablet contains Fluoxetine 20mg, a selective serotonin reuptake inhibitor (SSRI) commonly prescribed for the treatment of major depressive disorder, obsessive-compulsive disorder (OCD), panic disorder, and certain anxiety-related conditions. Fluoxetine functions by increasing the levels of serotonin, a neurotransmitter, in the brain, thereby helping to improve mood, emotional state, and anxiety symptoms. This medication is indicated for adults and adolescents aged 8 years and older, depending on the specific condition being treated. The usual dosage varies based on the diagnosis and patient response, with adjustments made by a healthcare professional to optimize therapeutic outcomes while minimizing adverse effects. Common side effects may include nausea, headache, insomnia, dry mouth, and gastrointestinal disturbances, though most patients tolerate the drug well. It is essential to adhere to prescribed dosing schedules and not discontinue treatment abruptly to avoid withdrawal symptoms. Fluoxetine may interact with other medications, including monoamine oxidase inhibitors (MAOIs), anticoagulants, and other serotonergic agents, necessitating careful medical supervision. Patients should inform their healthcare provider of any existing medical conditions, including liver or kidney impairment, and any history of bipolar disorder or seizures before initiating therapy with Haflur 20 Tablet. Regular follow-up is recommended to monitor efficacy and safety throughout the treatment course.
