1. What ATOZET is and what it is used for

ATOZET is a medicine to lower increased levels of cholesterol. ATOZET contains ezetimibe and atorvastatin.

ATOZET is used in adults to lower levels of total cholesterol, “bad” cholesterol (LDL cholesterol), and fatty substances called triglycerides in the blood. In addition, ATOZET raises levels of “good” cholesterol (HDL cholesterol).

ATOZET works to reduce your cholesterol in two ways. It reduces the cholesterol absorbed in your digestive tract, as well as the cholesterol your body makes by itself.

Cholesterol is one of several fatty substances found in the bloodstream. Your total cholesterol is made up mainly of LDL and HDL cholesterol.

LDL cholesterol is often called “bad” cholesterol because it can build up in the walls of your arteries forming plaque. Eventually this plaque build-up can lead to a narrowing of the arteries. This narrowing can slow or block blood flow to vital organs such as the heart and brain. This blocking of blood flow can result in a heart attack or stroke.

HDL cholesterol is often called “good” cholesterol because it helps keep the bad cholesterol from building up in the arteries and protects against heart disease.

Triglycerides are another form of fat in your blood that may increase your risk for heart disease. ATOZET is used for patients who cannot control their cholesterol levels by diet alone. You should stay on a cholesterol-lowering diet while taking this medicine.

ATOZET is used in addition to your cholesterol-lowering diet if you have:

  • a raised cholesterol level in your blood (primary hypercholesterolaemia [heterozygous familial and non-familial]) or elevated fat levels in your blood (mixed hyperlipidaemia)

    • that is not well controlled with a statin alone;
    • for which you have used a statin and ezetimibe as separate tablets.
  • a hereditary illness (homozygous familial hypercholesterolaemia) that increases the cholesterol level in your blood. You may also receive other treatments.
  • heart disease. ATOZET reduces the risk of heart attack, stroke, surgery to increase heart blood flow, or hospitalisation for chest pain.

ATOZET does not help you lose weight.

2. What you need to know before you take ATOZET

Do not take ATOZET if

  • you are allergic to ezetimibe, atorvastatin or any of the other ingredients of this medicine (listed in section 6)
  • you have or have ever had a disease that affects the liver
  • you have had any unexplained abnormal blood tests for liver function
  • you are a woman able to have children and are not using reliable contraception
  • you are pregnant, trying to become pregnant or are breast-feeding
  • you use the combination of glecaprevir/pibrentasvir in the treatment of hepatitis C.

Warnings and precautions

Talk to your doctor or pharmacist before taking ATOZET if

  • you have had a previous stroke with bleeding into the brain, or have small pockets of fluid in the brain from previous strokes
  • you have kidney problems
  • you have an under-active thyroid gland (hypothyroidism)
  • you have had repeated or unexplained muscle aches or pains, a personal history or family history of muscle problems
  • you have had previous muscular problems during treatment with other lipid-lowering medicines (e.g.

    other “statin” or “fibrate” medicines)

  • you regularly drink a large amount of alcohol
  • you have a history of liver disease
  • you are older than 70 years
  • you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this product
  • you are taking or have taken in the last 7 days a medicine called fusidic acid, (a medicine for bacterial infection) orally or by injection. The combination of fusidic acid and ATOZET can lead to serious muscle problems (rhabdomyolysis),
  • you have or have had myasthenia (a disease with general muscle weakness including in some cases muscles used when breathing), or ocular myasthenia (a disease causing eye muscle weakness) as statins may sometimes aggravate the condition or lead to the occurrence of myasthenia (see section 4).

Contact your doctor promptly if you experience unexplained muscle pain, tenderness, or weakness while taking ATOZET. This is because on rare occasions, muscle problems can be serious, including muscle breakdown resulting in kidney damage. Atorvastatin is known to cause muscle problems, and cases of muscle problems have also been reported with ezetimibe.

Also tell your doctor or pharmacist if you have a muscle weakness that is constant. Additional tests and medicines may be needed to diagnose and treat this.

Check with your doctor or pharmacist before taking ATOZET:

  • if you have severe respiratory failure.

If any of these apply to you (or you are not sure), talk to your doctor or pharmacist before taking ATOZET because your doctor will need to carry out a blood test before and possibly during your ATOZET treatment to predict your risk of muscle-related side effects. The risk of muscle-related side effects, e.g. rhabdomyolysis, is known to increase when certain medicines are taken at the same time (see section 2 “Other medicines and ATOZET”).

While you are on this medicine your doctor will monitor you closely if you have diabetes or are at risk of developing diabetes. You are likely to be at risk of developing diabetes if you have high levels of sugars and fats in your blood, are overweight and have high blood pressure.

Tell your doctor about all your medical conditions including allergies.

The combined use of ATOZET and fibrates (medicines for lowering cholesterol) should be avoided since the combined use of ATOZET and fibrates has not been studied.

Children

ATOZET is not recommended for children and adolescents.

Other medicines and ATOZET

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines, including those obtained without prescription.

There are some medicines that may change the effect of ATOZET or their effect may be changed by ATOZET (see section 3). This type of interaction could make one or both of the medicines less effective. Alternatively it could increase the risk or severity of side effects, including the important muscle wasting condition known as “rhabdomyolysis” described in section 4:

  • ciclosporin (a medicine often used in organ transplant patients)
  • erythromycin, clarithromycin, telithromycin, fusidic acid**, rifampicin (medicines for bacterial infections)
  • ketoconazole, itraconazole, voriconazole, fluconazole, posaconazole (medicines for fungal infections)
  • gemfibrozil, other fibrates, nicotinic acid, derivatives, colestipol, cholestyramine (medicines for regulating lipid levels)
  • some calcium channel blockers used for angina or high blood pressure, e.g. amlodipine, diltiazem
  • digoxin, verapamil, amiodarone (medicines to regulate your heart rhythm)
  • medicines used in the treatment of HIV, e.g. ritonavir, lopinavir, atazanavir, indinavir, darunavir, the combination of tipranavir/ritonavir, etc. (medicines for AIDS)
  • some medicines used in the treatment of hepatitis C, e.g. telaprevir, boceprevir and the combination of elbasvir/grazoprevir
  • daptomycin (a medicine used to treat complicated skin and skin structure infections and bacteraemia).

**If you need to take oral fusidic acid to treat a bacterial infection you will need to temporarily stop using this medicine. Your doctor will tell you when it is safe to restart ATOZET. Taking ATOZET with fusidic acid may rarely lead to muscle weakness, tenderness or pain (rhabdomyolysis). See more information regarding rhabdomyolysis in section 4.

  • Other medicines known to interact with ATOZET

    • oral contraceptives (medicines for preventing pregnancy)
    • stiripentol (an anticonvulsant medicine for epilepsy)
    • cimetidine (a medicine used for heartburn and peptic ulcers)
    • phenazone (a painkiller)
    • antacids (indigestion products containing aluminium or magnesium)
    • warfarin, phenprocoumon, acenocoumarol or fluindione (medicines to prevent blood clots)
    • colchicine (used to treat gout)
    • St John's wort (a medicine to treat depression).

Muscle-related side effects

A study that reviewed combined results from multiple clinical trials found that statins can sometimes cause a small increase in mild muscle symptoms in the first year of treatment. The study also demonstrated an increase in first episode of muscle pain or weakness symptoms being more likely for intensive statin treatment compared to moderate/less intense statin treatment. However, most (over 90%) muscle symptoms reported were not related to the statin itself.
