Fluoxetine is an antidepressant substance of the selective serotonin reuptake inhibitor (SSRI) class. It is a widely prescribed psychiatric medication used in the treatment of depression, obsessive compulsive disorder, and bulimia nervosa.

It is worth noting that antidepressants like fluoxetine have limited recreational potential. They may also reduce the action of certain serotonergic substances such as psychedelics and entactogens.

Individuals who are prescribed SSRIs that seek to use hallucinogenic substances for psychonautic or recreational purposes are advised to research potential interactions beforehand. It is usually advised to taper off any SSRIs before engaging in hallucinogen use.

Pharmacology

Fluoxetine acts by inhibiting the presynaptic reuptake of the neurotransmitter serotonin, resulting in higher levels of 5-hydroxytryptamine (5-HT) in various areas of the brain.

It is 5-HT selective due to its high affinity for 5-HT transporters, weak affinity for noradrenaline transporters and lack of affinity for dopamine transporters.

Among approved antidepressants, fluoxetine may be less effective than newer agents such as escitalopram. However, its very long elimination half-life of 1–3 days (acute) and 4–6 days (chronic) makes it attractive as a treatment for SSRI withdrawal symptoms.
