Drug Uses
Prozac is a drug used medically in the
treatment of depression, obsessive-compulsive disorder, bulimia nervosa,
premenstrual dysphoric disorder, and many other disorders. It is a psychotropic
drug for oral administration.
How Taken
Prozac usually is taken once or twice a
day. To be effective, it should be taken regularly. Make a habit of taking it at
the same time you do some other daily activity. It may be 4 weeks before you
feel any relief from your depression, but the drug's effects should last about 9
months after a 3-month treatment regimen. For obsessive-compulsive disorder, the
full effect may take 5 weeks to appear.
Warnings/Precautions
Unless you are directed to do so by your
doctor, do not take this medication if you are recovering from a heart attack or
if you have liver disease or diabetes. Prozac may cause you to become drowsy or
less alert and may affect your judgment. Therefore, driving or operating
dangerous machinery or participating in any hazardous activity that requires
full mental alertness is not recommended. While taking this medication, you may
feel dizzy or light-headed or actually faint when getting up from a lying or
sitting position. If getting up slowly doesn't help or if this problem
continues, notify your doctor. If you develop a skin rash or hives while taking
Prozac, discontinue use of the medication and notify your doctor immediately.
Prozac should be used with caution if you have a history of seizures. You should
discuss all of your medical conditions with your doctor before taking this
medication. Prozac can occasionally cause decreased appetite and weight loss,
especially in depressed people who are already underweight and in those with
bulimia. If you notice changes in your weight or appetite, tell your doctor. The
effects of Prozac during pregnancy have not been adequately studied. If you are
pregnant or plan to become pregnant, inform your doctor immediately. This
medication appears in breast milk, and breastfeeding is not recommended while
you are taking Prozac.
Missed Dose
If you miss a dose of Prozac and you
remember the same day, take it as soon as possible. If you do not remember until
the next day, skip the missed dose and go back to your regular dosing schedule.
Do not take 2 doses at once.

More Information

WARNING
Suicidality and Antidepressant Drugs —
Antidepressants increased the risk compared to placebo of suicidal thinking and
behavior (suicidality) in children, adolescents, and young adults in short-term
studies of major depressive disorder (MDD) and other psychiatric disorders.
Anyone considering the use of Prozac or any other antidepressant in a child,
adolescent, or young adult must balance this risk with the clinical need.
Short-term studies did not show an increase in the risk of suicidality with
antidepressants compared to placebo in adults beyond age 24; there was a
reduction in risk with antidepressants compared to placebo in adults aged 65 and
older. Depression and certain other psychiatric disorders are themselves
associated with increases in the risk of suicide. Patients of all ages who are
started on antidepressant therapy should be monitored appropriately and observed
closely for clinical worsening, suicidality, or unusual changes in behavior.
Families and caregivers should be advised of the need for close observation and
communication with the prescriber. Prozac is approved for use in pediatric
patients with MDD and obsessive compulsive disorder (OCD). (See WARNINGS,
Clinical worsening and suicide risk, PRECAUTIONS, Information for patients and precautions, Pediatric Use.)
