Methotrexate and Co-codamol drug interactions - a phase IV clinical study of FDA data
Summary:
Drug interactions are reported among people who take Methotrexate (methotrexate sodium) and Co-codamol (acetaminophen; codeine phosphate). Common drug interactions include pulmonary fibrosis among females and angina pectoris among males.
The phase IV clinical study analyzes what interactions people have when they take Methotrexate and Co-codamol. It is created by eHealthMe based on reports of 107 people who take the same drugs from the FDA, and is updated regularly.
