How It Works
Low doses of tricyclic antidepressant medications relieve pain and
cause drowsiness. Higher doses increase the levels of certain brain chemicals
that improve your mood.
Why It Is Used
Low doses of tricyclic antidepressants are used to relieve
long-lasting (chronic)
neck pain. They also cause drowsiness, which may
improve sleep and relieve fatigue. In higher doses, antidepressants can help to
relieve symptoms of depression; chronic pain can lead to depression.
How Well It Works
Using tricyclic antidepressants to relieve neck pain is not well
studied.1 Although researchers are exploring whether
and how well tricyclic antidepressants do affect chronic pain, it is known that
they can improve sleep. This may in turn improve your ability to cope with
pain.
Side Effects
Side effects vary among the different tricyclic antidepressants. If
you have severe side effects from one medication, try another.
Most side effects decrease over time. They may include:
- Constipation.
- Dry
mouth.
- Blurred vision.
- Drowsiness.
- Low
blood pressure.
- Weight gain.
- Tremors and
sweating.
- Urinary retention.
- Increased appetite.
Advisories. Health Canada and the U.S. Food
and Drug Administration (FDA) have issued
advisories 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 the doses are changed.
See Drug Reference for a full list of side effects. (Drug Reference
is not available in all systems.)
What To Think About
Tricyclic antidepressants may take 2 to 3 weeks to start working.
They may take 6 to 12 weeks in older adults.
These medications are generally not prescribed for people who have
heart problems.
People with chronic pain and depression are
often treated with a higher dosage of tricyclic antidepressant than the dose
used for chronic pain alone. They may also use another type of antidepressant,
a selective serotonin reuptake inhibitor (SSRI). SSRIs include sertraline
(Zoloft), fluoxetine (Prozac), fluvoxamine (Luvox), and paroxetine (Paxil). For
more information, see the topic Chronic Pain.
