Rosuvastatin belongs to a group of medicines known as statins. It regulates the amount of cholesterol and other lipids made by your body, and helps to reduce the risk of heart and blood vessel disease.
Take one dose each day.
Follow carefully any lifestyle advice you have been given such as stopping smoking, avoiding drinking too much alcohol, eating a healthy diet and taking exercise. These also help to reduce the risk of heart and blood vessel disease.
If you develop any unusual cramps or pains in your muscles, contact your doctor for advice as soon as possible.
|Type of medicine||A lipid-regulating medicine commonly known as a statin|
|Used for||Lowering cholesterol and other lipids in the blood; to reduce the risk of heart and blood vessel disease|
Lipids, or fats, are made naturally in your body from the food you eat. They are easily stored in your body and serve as a source of energy. Cholesterol and triglycerides are types of lipid. If the concentration of these lipids in your blood becomes too high, it leads to a condition called hyperlipidaemia. If it is the concentration of cholesterol which has become too high, it is called hypercholesterolaemia. Although a high blood concentration of lipids will not make you feel ill, it can cause a problem if it is left untreated.
People with high lipid levels can develop small fatty patches called atheroma. These patches develop when excess fat is deposited on to the walls of blood vessels. Over time, these patches can make a blood vessel narrower and this is called atherosclerosis (sometimes referred to as 'hardening of the arteries'). The 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.
Rosuvastatin belongs to a group of medicines known as statins (or HMG-CoA reductase inhibitors). It regulates the amount of cholesterol and other lipids made by your body. It does this by blocking the action of a certain enzyme (called HMG-CoA reductase) which your body needs to make the fats. 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 rosuvastatin
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 rosuvastatin it is important that your doctor knows:
- If you are pregnant, trying for a baby or breastfeeding.
- If you have any problems with the way your liver works, or if you have ever had a disease which has affected your liver.
- If you have an underactive thyroid gland.
- If you have a problem with unexplained muscle aches or pains, or if you (or a close relative) have ever had a muscle disorder.
- If you regularly drink large amounts of alcohol.
- If you have any problems with the way your kidneys work.
- If you have ever had an allergic reaction to a medicine.
- If you are taking any other medicines. This includes any medicines you are taking which are available to buy without a prescription, as well as herbal and complementary medicines.
How to take rosuvastatin
- Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about rosuvastatin and will provide you with a full list of the side-effects which you may experience from taking it.
- Take rosuvastatin once each day, exactly as your doctor tells you to. You will be started on a dose of 5 mg or 10 mg daily. If you are of Asian origin or over 70 years old, you will need to take the lower 5 mg dose to start with. Some other people will also need to take this lower dose at first. Your doctor will increase your dose after four weeks of treatment if this is considered necessary. There are several strengths of tablet available, so your doctor will tell you which strength is right for you.
- You can take rosuvastatin at a time of day to suit you. You should, however, try to take your doses at the same time of day each day. Swallow the tablet with a drink of water. You can take rosuvastatin 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, miss out the forgotten dose. Do not take two doses at the same time 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 that your doctor can check on your progress. You will need to have some blood tests from time to time. These are to measure your lipid levels and also to check that your liver has not been affected by taking rosuvastatin.
- Your doctor will give you advice about eating a healthy diet, cutting down on the amount of alcohol you normally drink, 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.
- Women taking rosuvastatin must avoid getting pregnant. Make sure you have discussed with your doctor which types of contraception are suitable for you and your partner.
- Some antacids can reduce the amount of rosuvastatin your body absorbs, so if possible, avoid taking indigestion remedies during the two hours before or during the two hours after you have taken rosuvastatin.
- Treatment with rosuvastatin is usually long-term unless you experience an adverse effect. You should continue to take the tablets regularly.
Can rosuvastatin cause problems?
Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the most common ones associated with rosuvastatin, although these tend to be mild. You will find a full list in the manufacturer's information leaflet supplied with your medicine. Unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.
|Common rosuvastatin side-effects (these affect less than 1 in 10 people)||What can I do if I experience this?|
|Muscle pain 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 rosuvastatin which is a severe form of muscle inflammation|
|Headache||Drink plenty of water and ask your pharmacist to recommend a suitable painkiller. If the headaches continue, let your doctor know|
|Constipation||Try to eat a well-balanced diet and drink several glasses of water each day|
|Feeling sick, tummy (abdominal) pain||Stick to simple meals - avoid rich or spicy food|
|Disturbed sleep, feeling dizzy or tired||Speak with your doctor if troublesome|
Important: rosuvastatin has been associated with some more serious side-effects in a very few people. Although these occur only rarely, it is important that you tell your doctor straightaway if you experience any of the following symptoms:
- If you develop any muscle cramps or pains, particularly if they are in your legs and you also feel unwell or have a high temperature (fever).
- If you feel short of breath or develop an unexplained cough. This is because (in very rare cases) rosuvastatin can cause a disease called interstitial lung disease.
- If you develop any allergic-type reactions, such as swelling around your mouth or face, or a skin rash.
If you experience any other symptoms which you think may be due to the tablets, speak with your doctor or pharmacist for further advice.
How to store rosuvastatin
- Keep all medicines out of the reach and sight of children.
- Store in a cool, dry place, away from direct heat and light.
