"i was prescribed exalgo by my physician about 3 weeks ago. i&#039;ve been a long term pain management patient, and we decided to make a change. i had been taking avinza. i am not certain that the mgs are equal, but the exalgo doesn&#039;t come close to helping as much as the avinza. i take as directed, each medicine is to be taken before bedtime, and since i have switched to exalgo, there have been many sleepless nights. maybe the dosage is not enough. this will be discussed with my physician.
