How It Works
Selective serotonin reuptake inhibitors
(SSRIs) affect brain chemicals (neurotransmitters) and reduce anxiety
and depression.
Why It Is Used
SSRIs are used to reduce anxiety and
depression associated with
social anxiety disorder.
How Well It Works
SSRIs reduce the severity of anxiety
related to anticipating a
panic attack when facing a feared event in social
anxiety disorder.
Side Effects
Side effects of SSRIs include:
- Dry mouth.
- Headache.
- Weight gain.
- Nausea, loss of appetite, or diarrhea.
- Feeling irritable or anxious.
- Problems sleeping.
- Drowsiness.
- Loss of sexual desire or ability.
- Tremor or shaky hands.
Advisories. Health Canada and the
U.S. Food and Drug Administration (FDA) have issued:
- Advisories on antidepressant medicines
and the risk of suicide. 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 headaches, with SSRIs (selective
serotonin reuptake inhibitors) or SNRIs (selective serotonin/norepinephrine
reuptake inhibitors). Taking these medicines together can cause a very rare but
serious condition called serotonin syndrome.

What To Think About
SSRIs usually are started at low
doses and increased gradually. You may start to feel better within 1 to 3 weeks
of taking an SSRI. But it can take as long as 6 to 8 weeks to see more
improvement. If you have questions or concerns about your medicines, or if you
do not notice any improvement by 3 weeks, talk to your doctor. 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 of anxiety symptoms.
People with
liver disease usually require lower doses of SSRIs.
Studies have
found daily use of SSRIs may increase the risk of bone fracture in adults over
age 50. Talk to your doctor about this risk before taking an SSRI.
