Prozac: Pro and Con
Suicidal thoughts and loss of motor control are not the only side effects of
these antidepressants. Others include:
- Severe withdrawal. It can take patients months to wean themselves off an
antidepressant like Paxil without suffering symptoms such as dizziness,
anxiety, and difficulty balancing.
- Significant weight gain, often after initial weight loss.
- A loss of effectiveness. Prozac, for example, wears off in about a third of
patients within a year.
- Sexual dysfunction, reported in as many as 30% to 60% of patients.
These important concerns are downplayed by Prozac's manufacturer, Eli Lilly
and Co. Moreover, the published risks are based on short-term studies. No one
really understands how normal functioning of the brain may be impaired by
Prozac-type antidepressants in the long run. Indeed, one worrisome study,
published in the March 2000 issue of Brain Research, indicates that
Prozac and Zoloft may be toxic to the very cells they target in the brain.
Does this mean that no one should take these antidepressants? Emphatically
not. I still prescribe Prozac and related medications for patients in my
practice. I've seen firsthand the benefits they offer. But any drug that also
has the potential for serious harm should be prescribed only by experts, and
then only with restraint and careful monitoring.
Patients should have moderate to severe depression symptoms that affect
them to the point that they risk real damage -- the loss of a job or a
relationship, or the abandonment of an important goal -- before they consider
starting antidepressant medication. Even then, these drugs should be used in
combination with other types of treatment, like psychotherapy, couples therapy,
or 12-step programs in order to ultimately reduce long-term dependence on the
If your doctor suggests an antidepressant, ask for a referral to a
psychologist or a psychiatrist for a second opinion. And should you start
taking the drug, don't just blindly renew your prescription over the telephone.
Sit down with your physician every six months or so to reassess your situation.
Ask questions: Do you still need it? Can you lower your dosage?
As Maura learned the hard way, these antidepressants are not right for
everyone. Don't accept the risks they may pose lightly.

the world can be the Physician's Desk Reference -- the guide to drugs
