Paroxetine CAS number 61869-08-7
medications are used to treat a variety of conditions, including depression
and other mental/mood disorders. These medications can help prevent suicidal
thoughts/attempts and provide other important benefits. However, studies
have shown that a small number of people (especially people younger than 25)
who take antidepressants for any condition may experience worsening
depression, other mental/mood symptoms, or suicidal thoughts/attempts.
Therefore, it is very important to talk with the doctor about the risks and
benefits of antidepressant medication (especially for people younger than
25), even if treatment is not for a mental/mood condition.
USES: Paroxetine is a selective serotonin reuptake inhibitor (SSRI)
used to treat depression, panic attacks, obsessive-compulsive disorder (OCD),
anxiety disorders, post-traumatic stress disorder, and a severe form of
premenstrual syndrome (premenstrual dysphoric disorder).
SSRIs work by helping to restore the balance of certain natural substances
in the brain (neurotransmitters such as serotonin). Paroxetine may improve
your mood, sleep, appetite, and energy level and may help restore your
interest in daily living. It may decrease anxiety/unreasonable fears,
persistent/troubling thoughts (obsessions), and unwanted urges that keep
returning (compulsions). It may decrease the number and severity of panic
attacks. Paroxetine may lessen premenstrual symptoms such as irritability,
increased appetite, and depression.
