Fluoxetine belongs to a class of drugs called serotonin reuptake inhibitors, so its mechanism of action is to increase levels of this neurotransmitter by selectively blocking its reuptake in the neuron membrane. It is administered orally, varying the dosage according to the pathology to be treated. At FastlyHealwe explain the different uses and side effects of fluoxetine .

Importance of serotonin

Serotonin is a neurotransmitter that intervenes in numerous vital processes within the nervous system, also acting as a modulator of norepinephrine and dopamine, related to problems such as anxiety , aggressiveness and fear.

The main functions of serotonin are:

  • Inhibition of fear and aggressiveness.
  • Appetite modulation, satiety.
  • Regulation of body temperature.
  • Inhibition of vomiting.
  • Modulation of mood, being directly related to depressive processes.
  • Participation in the control of cognitive, motor and perceptual activity
  • Regulation of hormone secretion, such as growth.

Low levels of this neurotransmitter are associated with depressive, anxious, and aggressive symptoms, sometimes including migraines or intestinal problems. To increase its levels it is important to have regular sleep cycles, practice pleasant activities, physical exercise and relaxation techniques. However, in certain pathologies that present with more severe symptoms, these recommendations may not be sufficient and therefore it is necessary to resort to medication with serotonin reuptake inhibitors such as fluoxetine.

Uses of fluoxetine

Fluoxetine is a drug that increases the levels of the neurotransmitter serotonin, this being beneficial for the treatment of the following pathologies:

  • Episodes of severe depression.
  • Obsessive compulsive disorder, consisting of a series of disturbing thoughts that drive the person suffering from it to repeat some acts several times.
  • Bulimia nervosa, which should be complemented with psychotherapy.
  • Panic attacks or phobias, causing patients a feeling of extreme terror and worry.
  • Moderate depressive episodes, if psychological therapy has not been effective after six sessions.
  • Premenstrual Dysphoric Disorder, including sudden mood swings, irritability, swelling, and increased breast tenderness.

Side effects of fluoxetine

The side effects of fluoxetine are rare and are directly related to increased serotonin levels.

  • Decreased appetite, causing weight loss.
  • Sleep disorders or insomnia.
  • Nervousness, restlessness, anxiety.
  • Decreased libido .
  • Alteration of attention.
  • Vomiting
  • Dry mouth
  • Skin rash, hives, or itching
  • Erectile dysfunction or ejaculation disorder
