Ampicillin and sulbactam and Febrile neutropenia - a phase IV clinical study of FDA data

Summary:

Febrile neutropenia is reported as a side effect among people who take Ampicillin and sulbactam (ampicillin sodium; sulbactam sodium), especially for people who are male, 60+ old, have been taking the drug for < 1 month also take Carboplatin, and have Acute myeloid leukaemia.

The phase IV clinical study analyzes which people have Febrile neutropenia when taking Ampicillin and sulbactam. It is created by eHealthMe based on reports of 962 people who have side effects when taking Ampicillin and sulbactam from the FDA, and is updated regularly.
