What is pravastatin?
Everyone has cholesterol and triglycerides in their blood. They are fatty substances needed by the body for many things. There are different types of cholesterol. Too much of the 'bad' cholesterol can block the blood vessels that supply your heart and brain with blood, and can cause heart attack, angina and stroke. The 'good' cholesterol helps to remove the bad cholesterol from the blood vessels. Pravastatin is used to lower the level of cholesterol in your blood.
Pravastatin belongs to a group of medicines called statins. Read more about statins — when are they used, their benefits and risks and other frequently asked questions about statins.
Pravastatin tablets are available in different strengths: 10 mg, 20 mg and 40 mg .
- The usual dose of pravastatin is 20 to 40 mg once a day.
- Always take pravastatin exactly as your doctor has told you. The pharmacy label on your medicine will tell you how much pravastatin to take, how often to take it, and any special instructions.
How to take pravastatin
- Timing: Take pravastatin once a day. Pravastatin is best taken in the evening but its alright to take it anytime of the day that suits you, at around the same time each day. You can take pravastatin with or without food.
- Limit drinking large amounts of alcohol while you are taking pravastatin. Heavy drinking can increase your risk of side effects such as problems with your liver.
- Missed dose: If you forget your dose, take it as soon as you remember that day. But, if it is nearly time for your next dose, just take the next dose at the usual time. Do not take double the dose.
- Keep taking pravastatin regularly. To reduce your cholesterol effectively, you must keep taking pravastatin every day. Treatment with pravastatin is usually long term.

- Do you have liver or kidney problems?
- Do you have problems with your thyroid?
- Do you have diabetes?
- Are your trying to get pregnant, think you might be pregnant, you're already pregnant, or you're breastfeeding?
- Do you drink large amounts of alcohol?
- Have you had, or do you have, a muscle disorder?

Precautions when taking pravastatin
- You may need to see your doctor regularly when you first start taking pravastatin to make sure the dose is right for you.
- To get the full benefit of a statin, it is important to keep a healthy diet and exercise often.
Like all medicines, pravastatin can cause side effects, although not everyone gets them. Often side effects improve as your body gets used to the new medicine.
Muscle pain or weakness
Some people will have muscle pain or weakness when taking statins. This is rarely serious and often goes away with time. If your pain comes on shortly after you start your statin, or gets worse, see your doctor. Your doctor will check an enzyme called creatine kinase to see if the aches and pains are possibly being caused or made worse by the statins. If so:
- a lower dose or a different statin may be prescribed, or
- you may choose to continue living with the aches because of the benefits of the statin, or
- you may discuss stopping taking your statin with your doctor.
Your doctor will also want to check for a rare but serious condition called rhabdomyolysis and will check any other medicines you are taking. Rhabdomyolysis can be caused by an interaction between statins and some other medicines.
