Heparin and Phlebothrombosis - a phase IV clinical study of FDA data

Summary:

Phlebothrombosis is reported as a side effect among people who take Heparin (heparin sodium), especially for people who are female, 60+ old, have been taking the drug for < 1 month also take Pulmicort, and have Pulmonary embolism.

The phase IV clinical study analyzes which people have Phlebothrombosis when taking Heparin. It is created by eHealthMe based on reports of 91,860 people who have side effects when taking Heparin from the FDA, and is updated regularly.
