Ceftriaxone and Brain oedema - a phase IV clinical study of FDA data

Summary:

Brain oedema is reported as a side effect among people who take Ceftriaxone (ceftriaxone sodium), especially for people who are male, 60+ old, have been taking the drug for < 1 month also take Vancomycin, and have Epilepsy.
