Sinemet and Left ventricular failure - a phase IV clinical study of FDA data

Summary:

Left ventricular failure is reported as a side effect among people who take Sinemet (carbidopa; levodopa), especially for people who are male, 60+ old, have been taking the drug for < 1 month also take Selegiline Hydrochloride, and have Cataplexy.

The phase IV clinical study analyzes which people have Left ventricular failure when taking Sinemet. It is created by eHealthMe based on reports of 28,351 people who have side effects when taking Sinemet from the FDA, and is updated regularly.

What is Sinemet?

Sinemet has active ingredients of carbidopa; levodopa. It is often used in parkinson's disease. eHealthMe is studying from 29,601 Sinemet users. Check the latest studies of Sinemet.

What is Left ventricular failure?

Left ventricular failure (left ventricle fails to contract forcefully) is found to be associated with 590 drugs and 666 conditions by eHealthMe. Check the latest studies of Left ventricular failure.
