What is Pravastatin?
Pravastatin belongs to a group of drugs called HMG CoA reductase inhibitors, or "statins."
Pravastatin is used together with diet to lower blood levels of "bad" cholesterol (low-density lipoprotein, or LDL), to increase levels of "good" cholesterol (high-density lipoprotein, or HDL), and to lower triglycerides (a type of fat in the blood).
Pravastatin is also used to lower the risk of stroke, heart attack, and other heart complications in people with or without coronary heart disease or other risk factors.
Pravastatin is used in adults and children who are at least 8 years old.
Warnings
You should not take pravastatin if you have active liver disease, or if you are pregnant or breastfeeding.
Tell your doctor about all your current medicines and any you start or stop using. Many drugs can interact, and some drugs should not be used together.
Stop taking pravastatin and tell your doctor at once if you become pregnant.
Pravastatin can cause the breakdown of muscle tissue, which can lead to kidney failure. Call your doctor right away if you have unexplained muscle pain, tenderness, or weakness especially if you also have fever, unusual tiredness, or dark urine.
Avoid eating foods that are high in fat or cholesterol. This medicine will not be as effective in lowering your cholesterol if you do not follow a cholesterol-lowering diet plan.
Avoid drinking alcohol. It can raise triglyceride levels and may increase your risk of liver damage.
How should I take Pravastatin
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.

What should I know about storage and disposal of this medication?
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.
What special dietary instructions should I follow?
Eat a low-fat, low-cholesterol diet. Be sure to follow all exercise and dietary recommendations made by your doctor or dietitian. You can also visit the National Cholesterol Education Program (NCEP) website for additional dietary information at http://www.nhlbi.nih.gov/health/public/heart/chol/chol_tlc.pdf.

Avoid eating foods high in fat or cholesterol, or pravastatin will not be as effective.
