Certain antidepressants may cause fatigue and drowsiness, especially during the early stages of treatment. While you are waiting for your body to adjust to your medication, the following are some tips for coping with fatigue from antidepressants:
- Take naps during the day.
- Get some mild exercise, like walking.
- Avoid driving or operating machinery until the fatigue passes.
- Take your medication at bedtime.
If the fatigue does not abate:
- Talk with your doctor about switching to a less sedating antidepressant.
- Talk with your doctor about augmenting your antidepressant with a psychostimulant such as Provigil (modafinil).
