Went to er for back spasms, they gave me 2 shots. 1 was flexeril (cyclobenzaprine hcl) and i don't remember what the other was. what is a common narcotic used with flexeril (cyclobenzaprine hcl)?

Back pain shot: In the usa the most common opioid shot is Dilaudid (hydromorphone). Another one commonly used is Demerol (meperidine hydrochloride) (meperidine) - this assumes you had an opioid. If it was not an opioid then you probably got toradol (ketorolac) which is an nsaid.

Demerol (meperidine hydrochloride): Demerol, (meperidine hydrochloride) Dilaudid and morphine are common because they are longer lasting.
