4. How and when to take it
Take pravastatin once a day in the evening. This is because your body makes most cholesterol at night.
Pravastatin doesn't upset the stomach, so you can take it with or without food. Swallow pravastatin tablets whole with a glass of water.
In adults, the usual dose is 10mg to 40mg once a day. Your dose depends on the reason for taking it, your cholesterol levels and what other medicines you're taking.
Ask your doctor or pharmacist for advice if you're unsure how much to take. Don't reduce your dose without talking to your doctor first.
In children aged 8 to 13 years old, the usual dose is 10mg to 20mg once a day. In children aged 14 to 17 years old, the dose may range from 10mg to 40mg daily.
Your doctor will work out the amount of pravastatin that's right for your child based on their age.
What if I forget to take it?
If you occasionally forget to take a dose, take your next dose the next day at the usual time. Never take 2 doses at the same time. Never take extra doses.
If you often forget doses, it may help to set an alarm to remind you. You could also ask your pharmacist for advice on other ways to help you remember to take your medicine.
What if I take too much?
Taking an extra dose of pravastatin by accident is unlikely to harm you.
Talk to your pharmacist or doctor if you're worried or if you take more than 1 extra dose.
5. Side effects
Pravastatin seems to be a very safe medicine and it's unusual to have side effects. However, different statins can affect people in different ways.
Talk to your doctor or pharmacist if side effects bother you or don't go away. They may recommend taking a different statin.
One rare but serious side effect is unexplained muscle aches and pains. This can happen a few weeks or months after you first start taking pravastatin. Report any unexplained muscle pain, tenderness or weakness to a doctor straight away.
Another very rare side effect can be memory loss. This usually goes away when you stop taking the medicine.
Serious side effects
It happens rarely, but less than 1 in 1,000 people taking pravastatin may have a serious side effect.
Stop taking pravastatin and call a doctor if you develop:
- unexplained muscle pain, tenderness, weakness or cramps - these can be a sign of muscle breakdown and kidney damage
- yellow skin or the whites of your eyes turn yellow, or if you have pale poo and dark pee - these can be signs of liver problems
- severe stomach pain - these can be a sign of inflammation of the pancreas
- a cough, feeling short of breath and weight loss - these can be signs of lung disease
Serious allergic reaction
In rare cases, it's possible to have a serious allergic reaction (anaphylaxis) to pravastatin.
Immediate action required: Call 999 or go to A&E if:
- you get a skin rash that may include itchy, red, swollen, blistered or peeling skin

8. Common questions
How does pravastatin work?
Pravastatin acts on the liver to stop it making cholesterol. This lowers your blood cholesterol level.
For the first 12 months on this medicine, you'll be offered a couple of routine tests to make sure your liver is working normally.
How long do statins take to work?
Your cholesterol levels should drop noticeably within 4 weeks - if you take your medicine regularly, as prescribed.
How long will I take pravastatin for?
Usually, treatment with a statin such as pravastatin is for life. The benefits will only continue for as long as you take it. If you stop taking pravastatin without starting a different treatment, your cholesterol level may rise again.
Are statins safe?
You may have read negative stories about statins, but they're thought to be very safe, effective medicines.
Statins are thought to have very few side effects. Sometimes the side effects that people report aren't related to their medicine. However, if you're concerned about the safety of statins, talk to your doctor.
Is it safe to take pravastatin for a long time?
Pravastatin is safe to take for a long time, even many years. In fact, it works best when you take it for a long time.
Statins have been used for nearly 30 years to lower cholesterol.
Is pravastatin addictive?
No, there's no evidence that pravastatin is addictive. You won't get any withdrawal symptoms when you stop taking it.
What will happen if I come off it?
You may want to stop pravastatin if you think you're having side effects. Talk to your doctor first to see if it really is a side effect of pravastatin or an unrelated problem. Your doctor may decide to lower your dose or change your medicine.
If you want to stop taking your medicine, it's important to find another way to lower your cholesterol.
Does it help to take supplements together with statins?
There's some interest in taking CoQ10 together with statins. However there's no firm evidence that taking CoQ10 at the same time as pravastatin will benefit your health. More research is needed.
If you decide to take a CoQ10 supplement, tell your doctor or pharmacist. Supplements can interfere with other medicines you may also be taking.
Will taking pravastatin increase my risk of diabetes?
If you're at high risk of developing type 2 diabetes, taking statins may slightly increase this risk. This is because statins can raise your blood sugar a little.
Speak to your doctor, who will be able to explain how the benefits of taking statins are likely to outweigh this small increased risk.
If you already have type 2 diabetes, your doctor may advise monitoring your blood sugar levels more closely for the first few months. Tell your doctor or diabetes nurse if you find it harder to control your blood sugar.
How does it compare with other medicines for high cholesterol?
Statins all work in the same way, but they differ in how well they lower cholesterol.
There are several other cholesterol-lowering statin medicines, including:
If you have a side effect with one statin, it may not happen with another. Some medicines don't mix well with one statin, but you can take them with a different one.
Your doctor will find the right statin and dose for you, depending on your medical history, cholesterol level and the other medicines you take.
Can I drive or ride a bike?
Occasionally, pravastatin can make you feel dizzy or have blurred or double vision. If this happens to you, do not drive or use machines or tools, until you feel better.
Will it affect my fertility?
There's no firm evidence to suggest that taking pravastatin will reduce fertility in either men or women.
However, speak to a pharmacist or your doctor before taking it if you're trying to get pregnant.
Can I drink alcohol with it?
Yes, you can drink alcohol while taking pravastatin.
However, drinking a lot of alcohol may increase the chances of you getting muscle and liver side effects.
Try to keep to the recommended guidelines of no more than 14 units of alcohol a week. A standard glass of wine (175ml) is 2 units. A pint of lager or beer is usually 2 to 3 units of alcohol.
Is there any food or drink I need to avoid?
You can eat and drink normally on pravastatin.
Unlike with other statins, such as simvastatin and atorvastatin, it's safe to drink grapefruit juice with pravastatin.
Can lifestyle changes help?
Reducing your cholesterol may mean you don't need to be prescribed a statin medicine. There are lifestyle changes you can make that will help lower your cholesterol:
