What should I know about fluoxetine before taking it?

You should not take fluoxetine if you are allergic to it or to any of its ingredients. Talk to your doctor before taking fluoxetine if you are receiving electroshock therapy, have recently had a heart attack, or have ever had liver disease, heart disease, diabetes, or seizures. Talk to your doctor before taking fluoxetine if you are pregnant, plan to become pregnant, or breastfeeding.

Fluoxetine may cause drowsiness, so do not drive or operate tools or machinery until you know how it will affect you.

Children, adolescents, and adults younger than 24 years of age may experience an increased risk of suicidal thoughts and behavior when taking fluoxetine. Adults may experience mental health changes as well, including worsening of depression, thoughts of suicide or self-harm, anxiety, agitation, panic attacks, insomnia, aggression, irritability, impulsivity, restlessness, and abnormal states of excitement. You should watch for these symptoms most carefully when you start using fluoxetine and when your dose has just been changed.

Fluoxetine can cause dizziness or lightheadedness when standing from a sitting or reclining position, so make sure to stand up slowly. If you continue to experience dizziness, lightheadedness, or fainting symptoms, talk to your doctor.

Fluoxetine can cause stomach bleeding when mixed with non-steroidal anti-inflammatory drugs (NSAIDs) like aspirin. Talk to your doctor about using NSAIDs, as well as any other medication or supplement use, while taking fluoxetine.

Fluoxetine can lead to decreased appetite and weight loss, especially if you are already underweight or suffering from an eating disorder. It may cause prolonged seizures in those who are receiving electroshock therapy.

Fluoxetine should not be stopped suddenly because agitation, anxiety, headache, insomnia, drowsiness, irritability can occur.
