Pravastatin is used with diet, weight-loss, and exercise to reduce the risk of heart attack and stroke and to decrease the chance that heart surgery will be needed in people who have heart disease or who are at risk of developing heart disease. Pravastatin is also used to reduce the amount of cholesterol (a fat-like substance) and other fatty substances in the blood. Pravastatin is in a class of medications called HMG-CoA reductase inhibitors (statins). It works by slowing the production of cholesterol in the body to decrease the amount of cholesterol that may build up on the walls of the arteries and block blood flow to the heart, brain, and other parts of the body.
Pravastatin comes as a tablet to take by mouth. It is usually taken once a day with or without food. Take pravastatin at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take pravastatin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Your doctor may start you on a low dose of pravastatin and gradually increase your dose, not more than once every 4 weeks.
Continue to take pravastatin even if you feel well. Do not stop taking pravastatin without talking to your doctor.
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
Before taking pravastatin,
- tell your doctor and pharmacist if you are allergic to pravastatin, any other medications, or any of the ingredients in pravastatin tablets. Ask your pharmacist for a list of the ingredients.
- tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Be sure to mention any of the following: cimetidine (Tagamet); colchicine (Colcrys); cyclosporine (Neoral, Sandimmune); ketoconazole (Nizoral); other cholesterol-lowering medications such as fenofibrate (Tricor), gemfibrozil (Lopid), and niacin (nicotinic acid, Niacor, Niaspan); certain HIV protease inhibitors including lopinavir and ritonavir (Kaletra), and ritonavir (Norvir) taken with darunavir (Prezista); and spironolactone (Aldactone). Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
- if you are taking cholestyramine (Questran) or colestipol (Cholestid), take them 4 hours before or 1 hour after pravastatin. If you are taking antacids, take them 1 hour before pravastatin.
- tell your doctor if you have liver disease. Your doctor will order laboratory tests to see how well your liver is working even if you do not think you have liver disease. Your doctor will probably tell you not to take pravastatin if you have liver disease or if the tests show that you may be developing liver disease.
- tell your doctor if you drink more than two alcoholic beverages per day, if you have ever had liver disease or if you have or have ever had low blood pressure, seizures, or thyroid or kidney disease.

- if you are having surgery, including dental surgery, tell the doctor or dentist that you are taking pravastatin. If you are hospitalized due to serious injury or infection, tell the doctor who treats you that you are taking pravastatin.
- ask your doctor about the safe use of alcoholic beverages while you are taking pravastatin. Alcohol can increase the risk of serious side effects.
