Fluoxetine: How It Works And What To Expect

Fluoxetine is a selective serotonin reuptake inhibitor (SSRI) antidepressant. Millions of people use this drug around the world. In this blog post, we’ll discuss alternative treatment options for depression and why it may be time to consider an alternative treatment option if you or your loved one has been taking Fluoxetine for more than six months.

What Is Fluoxetine?

Define Fluoxetine

Fluoxetine is an antidepressant that was initially for the treatment of depression, obsessive-compulsive disorder (OCD), bulimia nervosa, and panic disorder. Fluoxetine belongs to a class of drugs. These are selective serotonin reuptake inhibitors (SSRIs). Other SSRIs include fluvoxamine (Luvox), paroxetine (Paxil, Pexeva), sertraline (Zoloft), and citalopram (Celexa). Fluoxetine was approved by the FDA in 1987 for the treatment of depression under the brand name Prozac.

What Does Fluoxetine Treat?

Fluoxetine can help to treat these disorders:

Major Depressive Disorder

Fluoxetine can help to treat major depressive disorder. This is a mood disorder that has persistent feelings of sadness and loss of interest. This medicine is thought to work by increasing the activity of serotonin, a neurotransmitter that helps regulate mood and behavior.

Obsessive-Compulsive Disorder (OCD)

Fluoxetine is used in combination with psychotherapy for the treatment of OCD. There are two types of this disorder: one characterized by unwanted thoughts, such as fear about germs or concern over losing things; and another type where people perform repeated actions such as handwashing or checking locks repeatedly until it feels “just right”. Fluoxetine works on both types but is only indicated for symptom relief and is not approved to treat these disorders directly.

Bulimia Nervosa

This disease involves frequent episodes of binge eating followed by behaviors intended to avoid weight gains, such as self-induced vomiting or excessive exercise. Fluoxetine may help reduce the number of binge eating episodes. Furthermore, it may promote weight loss in people with bulimia nervosa.

Panic Disorder

This is a disorder that means repeated panic attacks, which are sudden feelings of terror. These may include chest pain, shortness of breath, dizziness, or nausea. Fluoxetine can help reduce the number of panic attacks. Furthermore, it can improve the quality of life in people with this condition.

How Does Fluoxetine Work?

Fluoxetine belongs to a class of drugs called selective serotonin reuptake inhibitors (SSRIs). SSRIs are the most common antidepressants. These work by blocking the reabsorption (reuptake) of serotonin in the brain. This increases the level of serotonin available in the brain. This as a result helps to improve mood or regulate behavior.

However, this medication should not be stopped abruptly. This can cause withdrawal symptoms. Talk to your doctor about how to safely stop taking fluoxetine.

Considerations When Taking Fluoxetine

  • Fluoxetine is usually taken once a day, in the morning or evening. The dose you take will depend on the disorder of the patient. It is important to take fluoxetine exactly as prescribed by your doctor and not to change the dose without talking to your healthcare provider first.
  • It may take several weeks for this medication to start working. You should continue taking it even if you feel better after a few days. If you experience any side effects, talk to your doctor about the treatment.
  • This medicine should not be taken with MAO inhibitors, such as isocarboxazid (Marplan), phenelzine (Nardil), or tranylcypromine (Parnate). These medications can cause serious side effects when taken together.
  • Fluoxetine should also not be taken during pregnancy unless it is prescribed by your doctor. This medication can increase the risk of birth defects. It is important to talk to your healthcare provider about the risks and benefits of taking fluoxetine if you are pregnant or breastfeeding.

Dosage of Fluoxetine 

The dosage of fluoxetine will vary depending on the condition of the consumer. Your doctor may prescribe a different dose than those listed here.

You can take this medication orally once daily with or without food and water, usually in the morning or evening. Swallow this medication whole; do not split, chew, crush, dissolve, snort/inhale (sniff) it because doing so can cause serious side effects such as high blood pressure and irregular heart rhythm that could result in death.

Furthermore, it is important to take this medication exactly as prescribed by your healthcare provider and continue taking it even if you feel better after a few days of treatment. If you stop taking fluoxetine suddenly or miss doses, talk to your healthcare provider about how to safely restart treatment.

Possible Side Effects of Fluoxetine 

Patients can generally tolerate fluoxetine. However, some people experience side effects when taking it. The most common side effects are:


This medicine may cause nausea. You can treat this with anti-nausea medications.


This medicine may cause diarrhea. You can treat these further by taking other medications or adjusting the dose of fluoxetine.

Weight Gain

Fluoxetine may cause some people to gain weight. Weight loss is also a possible side effect of this medication.

Sexual Dysfunction

This medicine may cause problems with sexual function such as difficulty achieving an erection or ejaculating. However, this problem usually goes away after you discontinue the intake of the medication.

Loss of Appetite

Fluoxetine may cause some people to lose their appetite. If you experience this symptom, it is important to eat regular meals and snacks to help avoid weight loss.


This medicine may cause drowsiness, especially when taken with other medications that can also cause drowsiness, such as antihistamines, pain relievers, and tranquilizers.
