Oh duh! I see that the prescribing info meant that both dac and led have many interactions with OTHER drugs.
I was thinking it meant they have many interactions with EACH OTHER.
Anyway, I am still unclear on the subject of whether dac and led have interactions with each other. I cannot find any information which suggests that they do. I also cannot find any evidence which proves that they don't. I want to know if the concentration of either drug will be lowered by the presence of the other during a switchover from led to dac, while keeping sof the same?
Possibly this is still one of the many as yet unanswered questions about using the DAAs.
