Side Effects of Using Lipitor

Lipitor is a prescription medication used for lowering cholesterol. It works by blocking the production of low-density lipoprotein (LDL), or "bad" cholesterol. It is also used to lower the risk of heart problems and stroke in people with type 2 diabetes.

Common Side Effects

• The most commonly reported reactions to Lipitor include headache, abdominal discomfort, gas, diarrhea or constipation, runny nose and other cold-like symptoms, muscle aches and skin rash.

Kidney Failure

• In rare cases, Lipitor can cause a breakdown in the skeletal muscle tissue, which can lead to kidney failure. Symptoms include muscle weakness and tenderness, flu-like symptoms, fever and dark colored urine.

Other Serious Reactions

• Other possible rare reactions include ruptured tendons, light sensitivity, pancreatitis, swelling, skin disorders and liver failure. Drinking alcohol while taking Lipitor can increase the risk of liver failure.

Pregnancy

• Lipitor is a class X drug, meaning it can cause serious birth defects and should not be taken by pregnant women, those planning to become pregnant, or while breastfeeding.

Interactions

• Certain medications should be avoided or used with caution while taking Lipitor. Erythromycins, antifungals and niacin may increase the risk of muscle disorders. Grapefruit should also be avoided as it may cause a dangerous reaction.
