Welchol vs Cholestyramine – Uses, Dosage, Side Effects, Differences

Welchol

It is the brand name of a drug called colesevelam that lowers LDL cholesterol in the blood. It belongs to a class of medications called bile acid-binding resins. Bile acid is a hydroxylated steroid synthesized in the liver from cholesterol.

This medication is produced by Daiichi Sankyo, the 2nd largest pharmaceutical company in Japan. It was first approved by the Food and Drug Administration in 2000.

Uses

It is typically used to lower blood sugar in individuals with high blood sugar levels. In the United States, there are more than 31 million people with diabetes and over 450 million worldwide. People with diabetes have a higher risk of life-threatening complications, like – heart disease, vision loss, kidney failure, amputation of toes or legs, stroke, premature death.

This medication is also used to lower LDL cholesterol. Having a high LDL (bad) cholesterol is strongly associated with an increased risk of heart disease. This is because LDL cholesterol tends to clog and harden arteries. Moreover, high levels of LDL cholesterol increase the risk of stroke, by facilitating the formation of cholesterol plaque along the inside of artery walls.

Occasionally, this medication is used together with other cholesterol-lowering drugs, like – fluvastatin (Lescol), atorvastatin (Lipitor), pravastatin (Pravachol), lovastatin (Mevacor), simvastatin (Zocor), or rosuvastatin (Crestor).

Note – while taking this medication, it is recommended to avoid eating foods which are high in cholesterol or fat since it will not be as effective in lowering your LDL cholesterol levels.

Dosage

The usual recommended dose is 6 tablets once per day or 3 tablets two times per day.

Regular physical exercise can provide other cardiovascular benefits, like – reduced blood pressure and weight loss. Also, at least 30 minutes of moderate physical exercise per day has been shown to decrease LDL cholesterol levels.

#3 Reduce Your Stress

According to studies, there is a link between excess emotional stress and high LDL and total cholesterol levels. The best method to reduce your stress is mindfulness meditation. Aim for about half an hour a day.
