Lipitor is a prescription medication used for the treatment of high levels of cholesterol. It is also used for the prevention of cardiovascular disease. Lipitor prevents the formation of cholesterol by inhibiting the HMG-CoA enzyme. The body uses cholesterol from food instead. Many side effects may occur with the use of Lipitor, including headache, insomnia, constipation, urinary tracts infections, respiratory side effects and muscle pain.
Headache
The most common side effect in individuals taking Lipitor is headache. According to the Drug Information Handbook, up to 17 percent may experience headache. You may take a pain reliever such as Tylenol for the headache; ask a pharmacist or physician which pain reliever is best for you. If the headache is persistent or gets worse, inform your health care provider.
Insomnia
Lipitor may also cause insomnia or difficulty falling asleep. Insomnia can be a troublesome side effect which can lead to fatigue and dizziness. Speak with you health care provider about your insomnia so that he may adjust your drug therapy adequately.

Constipation may occur in about 3 percent of individuals on Lipitor. Drinking plenty of fluids and consuming an adequate amount of fiber may help with constipation. Exercising on a regular basis may also help. Constipation is associated with flatulence, abdominal pain and stomach pain.
