"this medicine was prescribed to me before i got my wisdom teeth out due to them being impacted and causing a great deal of pain. i noticed immediately that it would provide relief for a long time(6 or more hours) compared to 800mg ibuprofen that would provide small relief for 2-3 hours. it also calmed me. i&#039;m usually a pretty anxious guy and was nervous about my surgery but this helped get me through until i could have permanent relief. only downside as i noticed i built a tolerance to my dose after a week."
