Uses of Prozac
Fluoxetine is used to treat depression, bulimia
(an eating disorder), obsessive compulsive disorders (OCD), and severe
symptoms of premenstrual syndrome (premenstrual dysphoric disorder-PMDD).
Prozac works by helping to restore the balance of certain natural
chemicals in the brain.
Prozac Directions
Take Prozac by mouth usually once daily in the morning, with
or without food; or as directed by your doctor. The dosage is based on your
medical condition and response to therapy. Some medical conditions may require
a different dosing schedule (e.g., twice daily in the morning and at noon)
as determined by your doctor. Take this medication exactly as prescribed.
It is important to continue taking Prozac even if you feel well. Also, do
not stop taking Prozac without consulting your doctor. It may take up to
4 weeks before the full benefit of Prozac takes effect.
Prozac Side Effects
Nausea, headache, trouble sleeping, dry mouth, drowsiness,

loss, unusual or severe mental/mood changes, uncontrolled movements

Prozac Precautions
Tell your doctor your medical history, especially of:
liver problems, kidney disease, seizures, heart problems, diabetes, any
allergies. Prozac may make you dizzy or drowsy; use caution
engaging in activities requiring alertness such as driving or using
machinery. Limit alcoholic beverages. Liquid preparations of Prozac may contain sugar and/or small amounts of alcohol. Caution is advised
if you have diabetes, alcohol dependence, or liver disease. Ask your doctor
or pharmacist about the safe use of Prozac. Caution is advised when using
Prozac in the elderly because they may be more sensitive to the effects
of the drug. Prozac should be used only when clearly needed during
pregnancy. Discuss the risks and benefits with your doctor. Prozac passes into breast milk. Because of the potential risk
to the infant, breast-feeding while using Prozac is not recommended.
Consult your doctor before breast-feeding.
Prozac Drug Interactions
Certain medications taken with Prozac could result in
serious, even fatal, drug interactions. Avoid taking MAO inhibitors

procarbazine, selegiline, tranylcypromine) within 2 weeks, and avoid
taking thioridazine within 5 weeks, before or after treatment with Prozac.

not recommended for use with: weight loss medicine (e.g., sibutramine,
phentermine), thioridazine, terfenadine, astemizole. Ask your doctor or

alprazolam), narcotic pain relievers (e.g., codeine), muscle relaxants,
psychiatric medicine (e.g., phenothiazines such as chlorpromazine),

all your medicines (e.g., cough-and-cold products) because they may

adjusted when fluoxetine is started or discontinued. Consult
your doctor. Do not start or stop any medicine without
doctor or pharmacist approval.
