Final answer:
Niacin is utilized to manage hyperlipidemia by increasing good cholesterol (HDL) and decreasing bad cholesterol (LDL) and triglycerides, but it can cause side effects like flushing, itching, and liver damage.
Step-by-step explanation:
Niacin, also known as nicotinic acid, is a medication used to treat hyperlipidemia, which is an elevation of lipids (fats) in the blood. Specifically, niacin is effective in increasing the levels of HDL cholesterol (high-density lipoprotein), which is often referred to as good cholesterol, while decreasing levels of LDL cholesterol (low-density lipoprotein) and triglycerides.
However, while niacin can be beneficial in managing cholesterol levels, it is not without side effects. Common side effects of niacin treatment include flushing, itching, gastrointestinal disturbances, and increased blood glucose levels. Less commonly, but more seriously, niacin use can lead to liver damage, gout, high blood pressure, and an increased risk of bleeding.
