Increased energy which may be pleasant or feel like anxiety, agitation or irritabliity. Zoloft and Paxil may sedate (rarely Prozac), Luvox most likely to sedate. Celexa is most neutral, regarding energy.



Decreased appetite, sometimes with nausea. Less
if taken with food. With time,
weight may increase.
25-40% experience
decreased sex drive or
response.


Less common: increased urinary frequency, dry mouth or sweating, vivid dreams.
Once a day for Prozac, Zoloft, Celexa, and Paxil. Very good safety profile.


No labs, no EKG typically needed. No heart side-effects. Few significant interactions except increases tricyclic antidepressant blood levels. Zoloft and Celexa lowest interactions.


Excellent for mild, moderate and severe depressions and anxiety disorders including panic, mixed, obsessive compulsive, post traumatic stress and atypical types. May help temper and impulsivity.


Very low risk in overdose. Reportedly, low risk in pregnancy and breast feeding.

SRI side effects (as with most meds) often lessen with time.


Paxil CR is a new Controlled Release, longer lasting, smoother version of Paxil.

Luvox, Paxil, Celexa, and Prozac available as generic. Prozac available in once a week form. All SRI help PMS.



Lexapro is a refined isomer version of Celexa.
Any SRI, especially Prozac, may agitate or disinhibit if excess energy occurs.


Switch to evening if sedation occurs. Takes 1-3 weeks to begin to help and 1-3 months for maximum effect.

Avoid combination or overlap with MAOI.


Discontinuation syndrome (nausea, dizziness, "flu-ish," "out of sorts") may occur if stopped suddenly without taper or skip one or several days. Not dangerous, but unpleasant. More likely with Paxil or Effexor, not with Prozac because it lasts longest.

FDA Caution: advise monitor for rare increased suicidal thoughts or behavior especially in kids when first starting medicine.

Same as other SRI plus sometimes increased sweat or constipation. Effexor increases both serotonin and norepinephrine thus affecting two important neurotransmitter systems, unlike other SRI's. May help attention. May be broader spectrum effect because of two transmitters increased.

Same as Effexor. Research shows some benefit against pain.

Slight risk increased blood pressure at doses over 200 mg total a day. (less than 5% chance.)

Discontinuation symptoms (see above) if stopped without taper or if multiple doses missed.

Cymbalta became available 9/04.  Rare liver injury especially if alcohol abuse.

Cymbalta
(Duloxetine)
capsule
20 mg
30 mg
60 mg
once or twice a day 30-120 mg usually 60 mg for adults Similar to SRI and Effexor above.

All these medications should be taken 7 days a week to be effective. Simultaneous use of alcohol or cigarettes and especially street drugs should be avoided. All antidepressants may increase mania risk in persons with Bipolar (manic-depressive) disorder. All medications should be avoided if possible in pregnancy.
