Pentoxifylline and Thiamine drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Pentoxifylline (pentoxifylline) and Thiamine (thiamine (vitamin b1)). Common drug interactions include pulmonary tuberculosis among females and peripheral ischaemia among males.

The phase IV clinical study analyzes what interactions people have when they take Pentoxifylline and Thiamine. It is created by eHealthMe based on reports of 16 people who take the same drugs from the FDA, and is updated regularly.
