Hi Christoffer, welcome to the forum, and congratulations on starting treatment with Epclusa, it's a really great drug . Regarding the use of Kratom with Epclusa,
a previous answer in this thread
by Dr James Freeman, FixHepC's founder, states that Kratom should be avoided when treated with Daclatasvir medication, and that "it should be ok, but..." (so maybe best avoided) when treated with Epclusa medication. He also said "I do tell my patients you can’t get problems from drugs you are not taking...". So it's probably wise to avoid it during treatment to eliminate any doubt. It's also worth noting that the patient in this thread also said "I felt so much better after finishing Epclusa I never bothered with kratom again".
