over 100 mg a day is quite a concern.
Norco (
hydrocodone) and
oxycodone are close to equivalent. Indeed, the overdose
epidemic was more common for hydrocodone simply because it was more avaiable until 2016. For that matter, 4 gm of
tylenol in a day is quite a concern. certainly 4 gm at one time of tylenol would be a hospitalizable overdose and 4 gm over a year is entirely safe. One day is a borderline interval. certainly any other tylenol along with it including in
cold medicines is quite dangerous.
Having a symptoms for years without it changing or new associated symptoms with it would strongly imply it isn't going to kill you today; I'm less certain about the safety of the medication.
Anyone taking over 100 mg of
narcotic a day WILL have pain when stopping it; it is called 'narcotic withdrawal'. Less obvious, but equally true, anyone taking 100 mg of narcotic a day will have their perception of any pain changed by it. This change in the perception of pain will last for at least weeks after stopping the narcotic.
One shouldn't take a medicine without knowing why one is taking it.
Narcotics are dangerous and high amounts are more dangerous.
Seeing a pain specialist who is NOT PAID BY THE VISIT (university based for example) would be someone who could give an unbiased opinion.
