|Type of medicine||A lipid-regulating drug commonly known as a statin|
|Used for||Lowering cholesterol and other lipids in the blood (including after an organ transplant)
To reduce the risk of heart and blood vessel disease
Lipid is another word for fat. Lipids are easily stored in your body and serve as a source of energy. Cholesterol is a lipid. It is made naturally in your body from the food you eat. When the concentration of cholesterol in your blood is too high, it is called hypercholesterolaemia.
In hypercholesterolaemia, small fatty patches called atheroma develop within the inside lining of your blood vessels. Over time, these patches can make a blood vessel narrower and this is called atherosclerosis or 'hardening of the arteries'. This narrowing reduces the blood flow through the artery and increases the risk of a number of heart and blood vessel diseases, such as heart attack and stroke.
Pravastatin reduces the amount of lipids such as cholesterol made by your body. It does this by blocking the action of a certain enzyme which is needed to make cholesterol. This lowers your risk of heart and blood vessel disease. It can also reduce this risk, even if your cholesterol levels are normal, if you are at an increased risk of heart disease.
Before taking pravastatin
Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking pravastatin it is important that your doctor or pharmacist knows:
- If you are pregnant, trying for a baby or breast-feeding.
- If you have any liver problems, or if you have ever had a disease which has affected your liver.
- If you have ever had muscle problems, or if you have repeated or unexplained muscle aches or pains.
- If you regularly drink large amounts of alcohol.
- If you have a thyroid disorder.
- If you have kidney problems.
- If you have porphyria (a rare inherited blood disorder).
- If you have ever had an allergic reaction to this or to any other medicine.
- If you are taking any other medicines, including those available to buy without a prescription, herbal and complementary medicines.
How to take pravastatin
- Before you start this treatment, read the manufacturer's printed information leaflet from inside the pack. The leaflet will give you more information about the brand of pravastatin you have been given and a full list of possible side-effects from taking it.
- Take pravastatin exactly as your doctor has told you. You should take one dose each day, preferably in the evening.
- You can take pravastatin tablets before or after food.
- If you forget to take a dose, take it as soon as you remember. If you do not remember until the following day, skip the missed dose. Do not take two doses together to make up for a forgotten dose.
Getting the most from your treatment
- Try to keep your regular appointments with your doctor. This is so your doctor can check on your progress. You will need to have blood tests, particularly when you first start treatment. The tests will check that your liver has not been affected by taking pravastatin, and may also measure your cholesterol level.
- Your doctor will give you advice about eating a healthy diet, reducing the amount of salt in your diet, stopping smoking and taking regular exercise. Following this advice will also help you to reduce your risk of developing heart and blood vessel disease.
- Cut down on the amount of alcohol you normally drink. This is because alcohol can increase the risk of side-effects to your liver.
- Women who could become pregnant should not take pravastatin unless they are using an effective contraceptive. If this affects you, ask your doctor for advice about suitable contraception.
- If you buy any medicines, check with a pharmacist that they are suitable to take with pravastatin.
Can pravastatin cause problems?
Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. These usually improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following side-effects continue or become troublesome.
|Possible pravastatin side-effects - these affect less than 1 in 100 people who take this medicine||What can I do if I experience this?|
|Muscle aches, pains, weakness, or tenderness||Although this may not be anything to be concerned about, you should tell your doctor about this. This is because there is a rare but serious side-effect of pravastatin which is a severe form of muscle inflammation|
|Headache||Ask your pharmacist to recommend a suitable painkiller|
|Constipation||Try to eat a well-balanced diet and drink plenty of water each day|
|Diarrhoea||Drink plenty of water to replace any lost fluids|
|Feeling sick, stomach ache, indigestion, wind||Stick to bland foods - avoid rich or spicy food|
|Blurred or double vision||If this happens, do not drive or use tools or machines while you are unable to see properly|
|Disturbed sleep, feeling dizzy or tired, forgetfulness, depression, sexual problems, itchy rash, thinning of hair, an increased need to pass urine particularly at night||Speak with your doctor if any of these become troublesome|
Important: if you experience any of the following rare but serious symptoms, stop taking pravastatin and contact your doctor for advice straightaway:
- Any unexplained shortness of breath or cough. This is because (in very rare cases) pravastatin may cause a disease called interstitial lung disease.
- Any swelling of your face or mouth, or a severe skin rash. These may be signs that you are allergic to pravastatin.
If you experience any other symptoms which you think may be due to this medicine, discuss them with your doctor or pharmacist.
How to store pravastatin
- Keep all medicines out of the reach and sight of children.
- Store in a cool, dry place, away from direct heat and light.
