I just started a suboxone program to get off of fentanyl and oxycodone. my blood pressure has gone up - is this related?

Opiate withdrawl: It could be related. Opiate withdrawl can cause a side effect of increased blood pressure but this should not last past 72 hours. If the symptoms get worse go to an emergency room

Not directly.: suboxone is a narcotic/narcotic blocker combination. neither is likely to change blood pressure HOWEVER, changing narcotics often produces some degree of withdrawal and this can chause a mild change in blood pressure.
