Getting the most out of NERLYNX

NERLYNX can only do its job if you commit to taking it every day. And during this time of physical and emotional readjustment, managing any stress you may experience is important to staying committed to NERLYNX.

Managing stress during treatment

Some women feel pressure to pick back up the responsibilities they had before their cancer diagnosis. Others feel a drop in the kind of support they experienced from their healthcare provider and friends that comes with fighting cancer.

Whatever you're feeling, if you can take time to understand and accept how you feel in the present moment— without judgment of those feelings—you can learn to better manage stress and anxiety.

Deep breathing is a proven way to reduce stress in the body. Things that happen when you're stressed, like increased heart rate, fast breathing, and high blood pressure, all decrease as you relax through deep breathing.

TRY BREATHING TO RELAX

  • Sit or lie flat in a comfortable position

  • Put one hand on your belly just below your ribs and the other hand on your chest

  • Take a deep breath in through your nose, and let your inhale push your hand out. Your chest shouldn't move

  • Breathe out through pursed lips as if you're whistling. Feel the hand on your belly go in, and use it to push all the air out

Do this routine 3 to 10 times. Take your time with each breath. When you're finished, compare how you feel now to when you first started.
