Is it possible for me to take tramadol with norco (hydrocodone and acetaminophen) and ativan?

Yes with caution: I would talk with the prescribing physician and review the specific regimen intended. The tramadol may be acting as a way of reducing the reliance on the relatively higher strength Norco (hydrocodone and acetaminophen) i hope. Additionally, the Lorazepam has a capacity for producing respiratory suppression and could be dangerous in the context of too many opioid therapies being administered simultaneously. Stay safe!
