Loraz and Cerebyx drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Loraz (lorazepam) and Cerebyx (fosphenytoin sodium). Common drug interactions include disseminated intravascular coagulation among females and flushing among males.

The phase IV clinical study analyzes what interactions people have when they take Loraz and Cerebyx. It is created by eHealthMe based on reports of 21 people who take the same drugs from the FDA, and is updated regularly.

What is Cerebyx?

Cerebyx has active ingredients of fosphenytoin sodium. eHealthMe is studying from 515 Cerebyx users. Check the latest studies of Cerebyx.

female:

Disseminated intravascular coagulation (systemic activation of blood coagulation)
Drug hypersensitivity
Encephalopathy (functioning of the brain is affected by some agent or condition)
Hepatic necrosis (large portions of liver die off due to severe liver disease)
Leukopenia (less number of white blood cells in blood)
Multi-organ failure (multisystem organ failure)
Renal tubular necrosis (death of kidney tubules)
Respiratory failure (inadequate gas exchange by the respiratory system)
Somnolence (a state of near-sleep, a strong desire for sleep)
Ventricular tachycardia (rapid heartbeat that originates in one of the lower chambers (the ventricles) of the heart)

male:

Flushing (the warm, red condition of human skin)
Paraesthesia (sensation of tingling, tickling, prickling, pricking, or burning of a person's skin with no apparent long-term physical effect)
Pruritus (severe itching of the skin)
Stevens-johnson syndrome (an immune-complex-mediated hypersensitivity disorder. it ranges from mild skin and mucous membrane lesions to a severe)
