Antidepressant medications, which are usually used to treat
depression, can be effective in preventing chronic
tension headaches. Antidepressants have some
pain-relieving properties and may reduce how often headaches occur and how long
they last. Antidepressants are also used to improve sleep problems.
Antidepressants that are used to reduce the frequency or duration of
tension headaches usually include:
- Tricyclic antidepressants.
- Selective
serotonin reuptake inhibitors (SSRIs).
Tricyclic antidepressants usually work better than SSRIs to prevent
chronic headaches.1 Amitriptyline, a tricyclic
antidepressant, has been proven to reduce how often tension headaches occur and
how long they last.2 If you do not respond well to
amitriptyline, you may try other tricyclic antidepressants, although they may
not work as well to relieve your headache.
Side effects of tricyclic antidepressants include:
- Dry
mouth.
- Constipation.
- Blurred
vision.
- Inability to urinate.
- Weight
gain.
- Low blood pressure when you stand up quickly.
Common side effects of SSRIs include:
- Nausea.
- Changes in
appetite.
- Diarrhea.
- Anxiety or
drowsiness.
- Sleep problems.
- Loss of sexual desire or
ability.
- Headaches.
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 the doses are changed.
