How long do the effects of an intramuscular Kenalog injection typically last? How long before the medication is totally cleared from the body?

2 doctors agree

In brief: Two weeks

is a guestimate.
Possibly longer. Kenalog is not a drug of abuse nor does it have many side effects, so wondering why you are concerned about total body clearance? You can look up patient information for Kenalog online.

Basically agree. But......Particularly interested in concern about duration of effect. Are you worried about latency of anti-inflammatory action? Answer as above although considerable attenuated after one week. Concern about adrenal suppression? Would delay trusting for one month. But If need treatment for the syndrome then clarify the etiology of the Addison. why did you have the injection?
