Lethargy

Lethargy is a heavy tiredness that shadows you through the day. It is a significant side effect of opioids (pronounced OH-pee-oydz and also called narcotics).

Here are some ways to feel less lethargic:

• Take smaller, more frequent doses of short-acting opioids. This usually causes less tiredness than higher doses taken less often. Talk to your doctor and nurse for advice on the best doses for you.
• Try to avoid other causes of lethargy, such as dehydration (not drinking enough), eating heavy foods (like red meat or whole milk ice cream), not getting out of bed, and not moving around.
• Exhaustion may be caused by depression. Antidepressant medications can be effective for both your mood and your pain.
• Don't keep your surroundings dim or dark. Bring daytime back into your life by pulling back the curtains and getting out of bed if you can.
• Even if you can't move around comfortably, keep your mind active. Read the newspaper or a novel, write a letter, or do a crossword puzzle.
• If lethargy persists and you are fighting to stay awake, you can drink caffeinated coffee or take caffeine supplements, if your doctor okays them.

Women with bone metastases may have a high calcium blood level, which can cause lethargy, confusion, and constipation. If you feel confused, have your calcium level checked to be sure it's within normal range.
