Learning Fluoxetine. Fluoxetine: uses Fluoxetine is a selective serotonin reuptake inhibitor ( SSRI ) used to treat depression, anxiety disorders ( panic attacks ) , obsessive-compulsive disorder ( OCD ) , a certain eating disorder ( bulimia ) , and a severe form of premenstrual syndrome ( premenstrual dysphoric disorder ) .
SSRIs work by helping to restore the balance of certain natural substances in brain ( neurotransmitters such as serotonin ) . Fluoxetine may improve your mood, sleep, appetite, and energy level and may help restore your interest in daily living. It may decrease anxiety/unreasonable fears, persistent/troubling thoughts ( obsessions ) , and unwanted urges that keep returning ( compulsions ) . It may decrease number and severity of panic attacks. Fluoxetine may lessen premenstrual symptoms such as irritability, increased appetite, and depression. It may decrease bingeing and purging behaviors in bulimia. Fluoxetine: how to use Read Medication Guide provided by your pharmacist before you start using Fluoxetine and each time we get a refill. If we have any questions, consult your doctor or pharmacist.
Take Fluoxetine by mouth with or without food, usually once daily or as directed by your doctor. Fluoxetine may make we either sleepy or wakeful. Therefore, depending on how Fluoxetine affects you, your doctor may direct you to take entire dose once daily in either the morning or evening. If you're taking Fluoxetine twice a day, your doctor may direct we to take it in the morning and at noon.
If you're taking Fluoxetine for premenstrual problems, your doctor may direct we to take it every day of the month or just for 2 weeks before your period through first full day of your period. To help you remember, mark your calendar.
If you're using liquid form of Fluoxetine, measure dose carefully using a special measuring device/spoon. Do not use a household spoon because we mayn't get correct dose.
The dosage is based on your medical condition and response to treatment. To reduce your risk of side effects, your doctor may start we at a low dose and gradually increase your dose. Follow your doctor's instructions carefully. Don't take more or less medication or take it more frequently than prescribed. Your condition won't improve any faster, and your risk of side effects will increase. Use Fluoxetine regularly in order to get most benefit from it. To help you remember, use it at the same time ( s ) each day.
It is important to continue taking Fluoxetine as prescribed even if we feel well. Don't stop taking Fluoxetine without first consulting your doctor. Some conditions may become worse when drug is abruptly stopped. Your dose may need to be gradually decreased.
We should see some improvement in 1 to 2 weeks. It may take several weeks before you feel the full benefit.
Tell your doctor if your condition doesn't improve or if it worsens.

Therefore, it's very important to talk with the doctor about risks and benefits of antidepressant medication ( especially for children/teenagers ) , even if treatment isn't for a mental/mood condition.
Tell doctor immediately if you notice worsening depression/other psychiatric conditions, unusual behavior changes ( including possible suicidal thoughts/attempts ) , or other mental/mood changes ( including new/worsening anxiety, panic attacks, trouble sleeping, irritability, hostile/angry feelings, impulsive actions, severe restlessness, very rapid speech ) .
