How It Works
Selective serotonin reuptake inhibitors (SSRIs) balance brain
chemicals (neurotransmitters) by making more serotonin available,
which reduces the number and severity of
panic attacks associated with
panic disorder.
Why It Is Used
SSRIs are frequently the first choice of medication for treating
panic disorder and are effective in reducing the number and severity of panic
attacks. SSRIs also are effective in reducing
anxiety associated with panic attacks and are
effective in treating
depression and
agoraphobia, both of which frequently occur with panic
disorder.1
How Well It Works
SSRIs reduce the severity and number of panic attacks as well as
anxiety related to anticipating a panic attack.2 It
generally takes several weeks before an SSRI is fully effective, and some
people may need to try more than one before they find one that works.
Side Effects
Side effects of SSRIs include:
- Dry
mouth.
- Headache.
- Nausea, loss of appetite, and
diarrhea.
- Feeling irritable or anxious.
- Problems
sleeping.
- Drowsiness.
- Loss of sexual desire or
ability.
- Tremor or shaky
hands.
- Weight gain.
Health Canada and U.S. FDA Advisories.
Health Canada and the U.S. Food and Drug Administration (FDA) have
issued:
- Advisories on antidepressant medicines
and the risk of suicide in children and adults. It is not recommended that
people stop using these medicines. Instead, a person taking antidepressants
should be watched for
warning signs of suicide. This is especially important
at the beginning of treatment or when doses are changed.
- Warnings about the antidepressants Paxil and Paxil CR
and birth defects. Taking these medicines in the first 12 weeks of pregnancy
may increase your chance of having a baby with a birth defect.
- A
warning about taking triptans, used for migraines, with SSRIs (selective
serotonin reuptake inhibitors) or SNRIs (selective serotonin/norepinephrine
reuptake inhibitors). Taking these medicines together can cause a serious
condition called serotonin syndrome.

What To Think About
SSRIs usually are started at low doses and increased gradually.
They may take several weeks to start working. If you experience side effects
that won't go away (such as sexual dysfunction), your doctor may change your
medication or combine it with another medication to help reduce such side
effects.
Never suddenly stop taking antidepressants.
The use of any antidepressant should be tapered off slowly and only under the
supervision of a doctor. Abruptly stopping antidepressant medications can cause
negative side effects or a relapse into a depressive episode or panic
disorder.
SSRIs generally have fewer side effects than tricyclic
antidepressants, which also are used to treat panic attacks. SSRIs also are
safer than tricyclic antidepressants in case of overdose, which makes SSRIs a
better treatment choice for people who have thoughts of suicide.
People with liver disease usually require lower doses of
SSRIs.
SSRIs are also used to treat
depression. SSRIs alone are not commonly used if you
have episodes of
mania, such as in
bipolar disorder.
