👩🏽⚕️ Additional questions (FAQs)
💬 What are Ezetimibe and Simvastatin / Vytorin tablets used for?
This is not an ordinary cholesterol pill! This is an extremely powerful and effective medicine that contains two types of medicine (Combination Medicine) in one pill for those whose 'bad cholesterol (High LDL)' cannot be reduced/controlled with one pill! This prevents heart attacks and strokes 100%.
💬 How do these two medications (Vytorin) work together to clear cholesterol from our bodies?
This attacks from two sides! 1. Ezetimibe - It goes to our intestines and blocks all the gates (NPC1L1 transporter) that absorb cholesterol/fat from the food we eat into the body (blood) and forcibly expels it with feces (Inhibits absorption). 2. Simvastatin - It goes to our liver and completely blocks the machine that makes new lipids/cholesterol in the liver (HMG-CoA Reductase). This battle will definitely dissolve cholesterol.
💬 What are the most dangerous dangers to be aware of when taking this powerful cholesterol pill (Vytorin)?
Although this is safe, the biggest danger is 'Myopathy/Rhabdomyolysis'! If you experience unbearable muscle pain, weakness, and dark urine, tell your doctor immediately, otherwise your kidneys may stop working and you may die. Also, this is forbidden for 'pregnant mothers' and those with 'liver disease'!
