1. Gerald Marks Gerald Marks United States says:

    I am 71 year old male and have suffered from progressive constipation for 15 years.  My doctor asked me to try Linzess 145, once a day.  At first, I believed some relief resulted.  After a couple months, whatever relief there was diminished.  This is an expensive drug and is not on my Rx Plan Formulary.  I no longer take Linzess.
