Krill and Ocrevus drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Krill (krill oil) and Ocrevus (ocrelizumab). Common drug interactions include urinary tract infection among females and multiple sclerosis relapse among males.

The phase IV clinical study analyzes what interactions people have when they take Krill and Ocrevus. It is created by eHealthMe based on reports of 24 people who take the same drugs from the FDA, and is updated regularly.
