FDA approved this potent medicine for the treatment of various psychological conditions. It belongs to a class of drugs called selective serotonin reuptake inhibitors (SSRIs). This powerful drug influences the brain's chemistry, helping to maintain mental balance.

Fluoxetine has demonstrated efficacy in treating a broad spectrum of psychological conditions. These include major depressive disorder, obsessive-compulsive disorder (OCD), panic disorder, bulimia, binge eating disorder, and premenstrual dysphoric disorder. It's also used to treat bipolar depression, including cases of treatment-resistant depression when combined with olanzapine.

Fluoxetine Tablet Uses

Fluoxetine, a versatile medication, has a wide range of uses in treating various mental health conditions, such as:

• Its primary application is to treat depression, providing relief to individuals struggling with persistent feelings of sadness and hopelessness.
• One of the most common fluoxetine uses is in the treatment of obsessive-compulsive disorder (OCD). 
• Drug fluoxetine also has an impact on treating panic disorder. Those who suffer from sudden, unexpected attacks of extreme fear and worry about these attacks can find relief through the use of fluoxetine. 
• Another significant use of fluoxetine is in the treatment of eating disorders, particularly bulimia. The medication helps to reduce binge-eating episodes and purging behaviours associated with this condition.

How Fluoxetine Tablet Works

Fluoxetine, a powerful antidepressant, can affect the brain's chemistry by increasing the amount of serotonin, a natural substance that helps maintain mental balance.

Research has given much evidence that serotonin plays a crucial role in treating depression. Patients with depression often have low concentrations of serotonin in their cerebrospinal fluid and fewer serotonin uptake sites on their platelets. Fluoxetine addresses this issue by increasing serotonin levels in various brain parts.

Can I Take Fluoxetine with Other Medicines?

• Fluoxetine interacts with a significant number of medications, making it crucial to consult a doctor before combining it with other drugs. 
• It's essential to avoid taking fluoxetine with monoamine oxidase (MAO) inhibitors, such as isocarboxazid, linezolid, methylene blue injection, phenelzine, selegiline, or tranylcypromine. Combining these medications can result in severe side effects, including confusion, agitation, restlessness, gastrointestinal symptoms, sudden high body temperature, or severe convulsions.
• Thioridazine and pimozide, in combination with fluoxetine, can increase the risk of serious heart problems. 
• Fluoxetine may cause serotonin syndrome when taken with certain medications. These include:
  • Amphetamines
  • Buspirone
  • Fentanyl
  • Lithium
  • Tryptophan
  • St. John's wort
  • Some pain or migraine medicines, such as meperidine, methadone, rizatriptan, sumatriptan, tramadol
  • Patients taking fluoxetine should be cautious when using blood-thinning medications, including NSAIDs or warfarin, as fluoxetine may increase the risk of bleeding problems.

Some commonly checked interactions with fluoxetine include:

• Antidepressants (e.g., duloxetine, bupropion)
• Antipsychotics (e.g., aripiprazole, quetiapine)
• Anxiety medications (e.g., alprazolam)
• Pain relievers (e.g., acetaminophen, hydrocodone)
• Stimulants (e.g., amphetamine/dextroamphetamine)

Dosing Information

• For adults with depression, the initial dose is typically 20 mg once a day in the morning. 
• In the treatment of bulimia nervosa, adults usually take 60 mg once a day in the morning. 
• For obsessive-compulsive disorder (OCD) in adults, the starting dose is 20 mg once a day in the morning.
