What is Fluoxetine

Fluoxetine is a selective serotonin reuptake inhibitor (SSRI) commonly used to treat depression, panic disorder, bulimia nervosa, obsessive-compulsive disorder, and other mental health conditions.

It works by increasing the levels of serotonin in the brain, which is a neurotransmitter that plays a key role in regulating mood, emotions, and behavior.

Fluoxetine is available in tablet, capsule, and liquid forms and is usually taken once daily in the morning or as directed by a healthcare provider.

It may take several weeks for Fluoxetine to start working, so it is important to continue taking the medication as prescribed even if you do not see immediate improvement in symptoms.


Duloxetine, a selective serotonin and norepinephrine reuptake inhibitor (SNRI), can interact with various substances and medications. It is important to be aware of these potential interactions to avoid adverse effects. Some common interactions include:

Substance/Medication Interaction
MAOIs (Monoamine Oxidase Inhibitors) Combining duloxetine with MAOIs can lead to a dangerous condition known as serotonin syndrome, which can cause symptoms like confusion, hallucinations, agitation, sweating, shivering, fast heart rate, muscle stiffness, twitching, loss of coordination, nausea, vomiting, or diarrhea.
NSAIDs (Nonsteroidal Anti-Inflammatory Drugs) NSAIDs can increase the risk of bleeding when taken with duloxetine, especially in elderly individuals or those with a history of gastrointestinal bleeding.
Alcohol Drinking alcohol while taking duloxetine can increase the risk of liver damage and may worsen the central nervous system depressant effects of both substances.
Warfarin Duloxetine may increase the effects of warfarin, a blood thinner, and lead to an increased risk of bleeding.
