Fluoxetine is a medication used to treat depression, certain eating disorders, obsessive-compulsive disorder, and panic disorder. It belongs to a class of drugs known as selective serotonin reuptake inhibitors (SSRIs), which increase serotonin levels in the brain.

Fluoxetine is prescribed for mental health conditions like:

• Major depressive disorder (depression)
  
• Eating disorders (primarily bulimia nervosa)
  
• Obsessive-compulsive disorder
  
• Panic disorder and panic attacks
  
  

Fluoxetine belongs to a class of drugs called selective serotonin reuptake inhibitors. These drugs work by blocking the reuptake of serotonin, a neurotransmitter that plays a crucial role in stabilizing mood. By blocking the reuptake of serotonin, these drugs increase levels of serotonin in the brain.

Fluoxetine is available in various forms:

• Oral capsules: Available in immediate and delayed-release forms
  
• Oral tablets
  
• Oral solution (liquid)
  
  

The dosage and length of treatment depend on the condition being treated, its severity, and how you tolerate the medication.

Follow your healthcare provider's instructions regarding dosage and schedule. Do not exceed the prescribed dose or duration of treatment without consulting your provider.

The effectiveness of fluoxetine and the time it takes to notice improvement can vary among individuals. In the treatment of depression, it may take several weeks to feel the full benefit of the medication.

Continue taking fluoxetine as prescribed even if you start feeling better. Do not abruptly stop the medication, as it may lead to a return of symptoms or withdrawal-like effects.

While fluoxetine is primarily used for treating depression, obsessive-compulsive disorder, bulimia nervosa, and panic disorder, healthcare providers may sometimes prescribe it off-label for other conditions related to mood or anxiety.

Discuss any alternative uses of fluoxetine with your healthcare provider.
