      • Works best when taken regularly instead of as-needed.
      • Especially useful for people with chronic pain problems.

      • Swallow it whole. Don't crush, chew, or split the medicine.
      • Can make you dizzy or drowsy.
      • Avoid activities that need you to be fully alert until you know how it affects you.
      • Take it with food to lower the chance of an upset stomach.
      • Constipation is common and may not go away while you're taking this medicine. Drinking lots of water and taking laxatives can help.
      • Talk to your doctor if it doesn't help enough for your pain, or if the side effects are really bad.
