How It Works
Selective serotonin reuptake inhibitors
(SSRIs) can balance certain brain chemicals called
neurotransmitters. When these brain chemicals are in
proper balance, symptoms of
depression may be relieved.
Why It Is Used
Selective serotonin reuptake
inhibitors are used to treat depression and may help relieve pain after a
stroke.
How Well It Works
SSRIs are as effective in treating
depression as other types of antidepressants, such as tricyclic or tetracyclic
antidepressants and MAOIs (monoamine oxidase inhibitors), but they have
different and often less severe side effects. Some studies show that these
medicines also help relieve chronic pain, such as pain resulting from a
stroke.
Side Effects
Side effects of SSRIs include:
- Nausea, loss of appetite,
diarrhea.
- Anxiety or irritability.
- Problems sleeping or
drowsiness.
- Loss of sexual desire or ability.
- Headaches
or dizziness.
FDA Advisories. The U.S. Food and
Drug Administration (FDA) has issued:
- An
advisory on antidepressant medicines and the risk of
suicide. The FDA does not recommend 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.
- A
warning 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.
See Drug Reference for a full list of side effects. (Drug
Reference is not available in all systems.)
What To Think About
You may start to feel better
after 1 to 3 weeks of taking an SSRI. But it can take as many 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.
SSRIs can be safer than tricyclic or tetracyclic
antidepressants, because they do not cause death if taken in large quantities
(overdose). SSRIs usually are well tolerated and effective. SSRIs also may be
safer for older adults, because the side effects are more tolerable.
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.
Sexual dysfunction can be a
significant problem for some people while taking an SSRI. Other antidepressants
such as bupropion (Wellbutrin, for example) may be less likely to cause
significant sexual dysfunction as a side effect and may be used instead of, or
in addition to, an SSRI.
A medicine such as
sildenafil (Viagra) may help both men
and women who have sexual problems caused by SSRIs.1, 2
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 medicines can cause negative side effects or a relapse
into another depressive episode.
