"i am a rn and i have been taking darvocet n-100 for several months for a herniated disc in my lower back. it is a good drug for those of you who do not want or can&#039;t take other narcotics but unfortunately it is a narcotic and like all the others it has side effects and is addictive. i take because i don&#039;t want to take lortab and percocet which are even more addictive than darvocet. if you have to take it use caution and know what side effects to look for."
