Specifically speaking about Predinsone – no known interaction says Dr. Trina Hazzah (oncologist)
in an interview with Angela Ardilino founder of CBD Dog Health and MyCo Dogs. It is said to offer improved synergistic effects and additive effects.
As it relates to chemotherapy, radiation therapy, targeted therapy, she suggests administering Cannabis immediately before these treatments. Literature supports synergistic and additive effects. She stated if you have to give these treatments anyway, why not support the body further with CBD.
With Immunotherapy this may be adjusted and require more caution.
Always start low and slow to monitor the individual response.
In most cases cannabis is considered safe along side most meds. Where to excise most caution is with enzymes involving CYP450, especially if using cannabis at higher does. Reseach currently shows little to no interaction in lower doses.
