Fluoxetine
About Fluoxetine
Fluoxetine belongs to a group of medicines called antidepressants used to treat a major depressive disorder, obsessive-compulsive disorder (OCD), bulimia nervosa (eating disorder), and panic disorder. Depression is a mood disorder characterised by the feeling of sadness, unhappiness, anger, hopelessness or loss that interferes with a person’s daily activities.
Fluoxetine contains ‘Fluoxetine’ which is a selective serotonin reuptake inhibitor. It works by inhibiting the reuptake of serotonin by nerves, a mood-enhancing chemical messenger in the brain which communicates between brain cells. This helps in an increase in serotonin concentrations in the nerve synapse, thereby helps in regulating mood and treats depression.
Take Fluoxetine as prescribed. You are advised to take Fluoxetine for as long as your doctor has prescribed it for you depending on your medical condition and response to the treatment. In some cases, you may experience certain common side-effects such as insomnia (difficulty sleeping), headache, diarrhoea, nausea, fatigue, dry mouth, loss of appetite, and indigestion. Most of these side-effects do not require medical attention and will resolve gradually over time. However, you are advised to talk to your doctor if you experience these side-effects persistently.
Please do not stop taking Fluoxetine on your own as it could lead to withdrawal symptoms. Do not take Fluoxetine if you are pregnant or breastfeeding unless prescribed. Do not drive or operate machinery as Fluoxetine may cause dizziness and might impair your reactions. Fluoxetine should not be given to children below 8years as the safety and effectiveness have not been established. Avoid consuming alcohol along with Fluoxetine as it could lead to increased dizziness. Keep your doctor informed about your health condition and medicines to rule out any side-effects.
