===========================================================
Prozac is an antidepressant medication which was introduced
for use in the United States in December, 1987. Since that
time, Prozac has become the most widely prescribed
antidepressant in America. Prozac is FDA approved for the
the treatment of depression, and has been found useful in
the treatment of Obsessive Compulsive Disorder, Bulimia,
Panic Disorder, and other conditions. Prozac is manufactured
by the Dista Division of Eli Lilly, Inc. No generic
equivalent of Prozac is available at this time.
Prozac is not habit forming and does not induce euphoria.
It exerts its effects through the neuro-transmitter
serotonin, a substance in the brain involved with the
regulation of mood, sleep, and appetite. Prozac is a
specific serotonin reuptake inhibitor.
Most patients taking Prozac experience minimal or no side
effects. Some of the more common side effects of Prozac are
listed below:
- Mild, transient nausea and/or headache, which usually
resolve over a few days. Rarely, Prozac can cause
loose stools or diarrhea.
- Mild weight loss (e.g., 3-5 pounds).
- Increased nervousness, "jitteriness", and/or insomnia:
If these side effects occur, they often resolve over
two to three weeks.
- An{*filter*}ia (difficulty reaching {*filter*}): this can
occur in both women and men. This side effect may be
more frequent or more severe at higher doses.
- Induction of mania: individuals with a history of
Bipolar (Manic-Depressive) Illness or with a family
history of Bipolar Disorder may be at higher risk for a
switch from depression to mania while taking Prozac.
All antidepressant medications may share this risk.
- Skin rash: a focal, patchy, itchy red rash, often
involving the arms, face, and chest, which may be
associated with {*filter*} swelling or joint pain. This is
actually an allergic reaction, not a side effect.
Sensational allegations that Prozac is associated with an
increased risk of suicide or {*filter*} behavior have not been
substantiated in several large scale studies. The risk of
suicide appears to be no different for patients taking
Prozac compared to patients taking other antidepressant
medication. Suicide is a risk associated with depressive
illnesses and with other psychiatric disorders.
Prozac is classified as a "Pregnancy Category B" drug;
pregnant rats and rabbits exposed to high doses of Prozac
showed no harm to the fetus from the drug. There are
several reports of exposure to Prozac during human pregnancy
with no identifiable adverse effects. Nevertheless, Prozac
should not ordinarily be taken while pregnant or
{*filter*}feeding, and patients who plan to become pregnant
should be off Prozac at least one month before becoming
pregnant.
Patients taking Prozac generally should avoid {*filter*}ic
beverages; Prozac does not cause cumulative sedation when
taken concomittantly with {*filter*}, but most authorities
recommend that recovering depressives keep {*filter*} intake to
a minimum or abstain altogether. Prozac can alter the
liver's ability to clear other medications from the body,
raising or lowering the levels of other medications. Most
such interactions are not clinically significant, but
patients taking anticoagulants ({*filter*} thinners) should have
clotting times checked.
The proper dose of Prozac varies from one capsule three
times a week to five capsules a day. The usual dose for
depression is one capsule daily in the morning. Some
patients feel noticeably better within a few days of
starting Prozac, but many people begin to feel better only
after taking the medication for three or four weeks or more.
When antidpressant medication such as Prozac is helpful,
some psychiatrists recommend that medicine be continued for
at least a few months after a person is really feeling well
(for a total duration of treatment of at least six months to
one year). This may reduce the risk of a recurrence of
depression after medication is discontinued.
Patients taking Prozac should contact their doctor
immediately if suspicious skin rash occurs, or if
nervousness or insomnia are troublesome.
