High cholesterol raises the risk of having a heart attack or stroke. Cholesterol can stick to blood vessel walls and cause a buildup of plaque. This narrows the arteries and reduces the amount of blood and oxygen that reaches the heart and/or brain. In addition, pieces of plaque can break off and block blood vessels. Making lifestyle changes such as eating a healthy diet and getting regular exercise are important tools in bringing cholesterol levels down. Sometimes medication is required as well. Cholesterol medication can have side effects, so talk to your doctor about the options that are best for you.
Cramps and Diarrhea
In most cases the side effects from cholesterol lowering medications are mild and rare, states the American Academy of Family Physicians. However, some patients on these drugs experience abdominal cramps or pain; bloating; gas; skin that becomes warm, red or flushed; headaches; vomiting; and diarrhea. If these side effects interrupt daily life, switching to another medication or lowering the dose may help to resolve any problems.
Muscle Pain
Cholesterol medication usually needs to be continued for life so it is important to find one that is well tolerated. The American Heart Association suggests consulting a physician if side effects such as muscle pain or weakness occur. In rare cases muscle problems can become severe and may lead to problems with the liver.
Dizziness
Taking two or medications together can increase the risk of side effects. When taking these drugs the Mayo Clinic notes that dizziness, fatigue, shortness of breath and irregular heart rhythms may occur. Some of these side effects can be exacerbated by certain foods such as grapefruit juice.
