Statins can also cause an uncommon condition called myopathy. Myopathy cause muscle damage and, in some cases, muscle and joint pain. The risk for myopathy increases with higher doses. The following increases one's risk of myopathy
- Older age
- Small size or frailty
- Alcohol abuse
- Hypothyroidism
- Use of multiple medications
There is also a higher risk of myopathy if statins are used before surgery.
Statins also can effect the liver, particularly at higher doses, so periodic liver function tests should be done. Statins should not be taken by anyone with liver problems or by women who are pregnant or breast-feeding.
Nicotinic Acid (Niacin). Nicotinic acid is the active compound found in niacin (vitamin B3). It raises HDL levels more than any other anti-cholesterol drug, and is the first choice for patients with low HDL levels. Nicotinic acid is also extremely effective in reducing triglyceride levels. It may be beneficial for some patients with PAD.
Brands of nicotinic acid include Niacor, Nicolar, and Slo-Niacin. An extended-release form (Niaspan), taken at bedtime, may have fewer side effects than other types of niacin. Although niacin is available over-the-counter, the active form used for cholesterol is given in much higher doses and is available only by prescription. It is important to take this medication under a doctor's direction in order to ensure its safety and effectiveness. Combinations with other drugs, particularly statins, may add significant benefits.
Many patients can not tolerate the side effects of niacin. About a quarter of patients taking rapid-acting forms of nicotinic acid stop taking them. The most common side effects are flushing of the face and neck, itching, headache, blurred vision, and dizziness. They can occur between 5 minutes to hours after taking the drug and can last for varying lengths of time. The body does get used to these effects eventually, so they generally go away. Gastrointestinal problems are common. Other side effects include dry skin and mucous membranes and darkening of the skin.
