Lipitor Oral: Uses, Side Effects, Interactions, Pictures, Warnings & Dosing


Atorvastatin is used along with a proper diet to help lower “bad” cholesterol and fats (such as LDL, triglycerides) and raise “good” cholesterol (HDL) in the blood. It belongs to a group of drugs known as “statins.” It works by reducing the amount of cholesterol made by the liver. Lowering “bad” cholesterol and triglycerides and raising “good” cholesterol decreases the risk of heart disease and helps prevent strokes and heart attacks.In addition to eating a proper diet (such as a low-cholesterol/low-fat diet), other lifestyle changes that may help this medication work better include exercising, losing weight if overweight, and stopping smoking. Consult your doctor for more details.

How to use Lipitor

Read the Patient Information Leaflet if available from your pharmacist before you start taking atorvastatin and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Take this medication by mouth with or without food as directed by your doctor, usually once daily.

The dosage is based on your medical condition, response to treatment, age, and other medications you may be taking. Be sure to tell your doctor and pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).

Avoid eating grapefruit or drinking grapefruit juice while using this medication unless your doctor or pharmacist says you may do so safely. Grapefruit can increase the chance of side effects with this medicine. Ask your doctor or pharmacist for more details.

If you also take certain other drugs to lower your cholesterol (bile acid-binding resins such as cholestyramine or colestipol), take atorvastatin at least 1 hour before or at least 4 hours after taking these medications. These products can react with atorvastatin, preventing its full absorption.

Take this medication regularly in order to get the most benefit from it. Remember to take it at the same time each day. Keep taking this medication even if you feel well. Most people with high cholesterol or triglycerides do not feel sick.

It is very important to continue to follow your doctor’s advice about diet and exercise. It may take up to 4 weeks before you get the full benefit of this drug.

Side Effects

Taking atorvastatin with other medicines and herbal supplements

Cautions with other medicines

Some medicines can affect the way atorvastatin works and can increase the chances of you having serious side effects, such as muscle damage.

Tell your doctor or pharmacist if you are taking any of the following medicines:

  • antibiotics such as erythromycin, clarithromycin, rifampicin or fusidic acid
  • antifungals such as ketoconazole, voriconazole or fluconazole
  • some HIV medicines
  • some hepatitis C medicines
  • warfarin, a medicine to help prevent blood clots
  • ciclosporin, a medicine for psoriasis and rheumatoid arthritis
  • colchicine, a medicine for gout
  • contraceptive pills, such as the combined pill
  • verapamil, diltiazem or amlodipine, medicines for high blood pressure and heart problems
  • amiodarone, a medicine that helps if you have an irregular heartbeat (atrial fibrillation)

If you’re taking atorvastatin and need to take one of these medicines, your doctor may:

  • prescribe a lower dose of atorvastatin
  • prescribe a different statin medicine
  • recommend that you stop taking atorvastatin for a while

These are not all the medicines that can affect the way atorvastatin works. For a full list see the leaflet inside your medicine packet or check with your pharmacist.

Mixing atorvastatin with herbal remedies and supplements

St John’s wort, a herbal remedy taken for depression, reduces the amount of atorvastatin in your blood, so it does not work as well.

Talk to your doctor if you’re thinking about starting St John’s wort, as it will change how well atorvastatin works.

Sometimes, people take a supplement called CoQ10 with statins. There’s no clear evidence that taking it at the same time as atorvastatin benefits your health.

If you decide to take a CoQ10 supplement, tell your doctor or pharmacist. Supplements can affect the way other medicines you’re taking work.

There’s not enough information to say that other herbal remedies and supplements are safe to take with atorvastatin. They’re not tested in the same way as pharmacy and prescription medicines.

Medicine safety

Tell your doctor or pharmacist if you’re taking any other medicines, including herbal remedies, vitamins or supplements.

Lipitor tablets 20 mg, 30 pcs 10 Dosage form

Coated tablets

Indications for use

Primary hypercholesterolemia (heterozygous familial and non-familial hypercholesterolemia, Frederickson type IIa), combined (mixed) hyperlipidemia (Frederickson type IIb and III), dysbetalipoproteinemia (Frederickson type III) (as an adjunct to diet), familial endogenous hypertriglyceridemia (Frederickson type IV), resistant to dietary treatment.

Homozygous hereditary hypercholesterolemia (as an adjunct to lipid-lowering therapy, including autohemotransfusion of LDL-purified blood).

Also indications for treatment are cardiovascular diseases against the background of dyslipidemia, secondary prevention in order to reduce the overall risk of death, myocardial infarction and re-hospitalization for angina pectoris.


Hypersensitivity to the components of the drug, active liver diseases (including active chronic hepatitis, chronic alcoholic hepatitis), increased activity of “liver” transaminases (more than 3 times) of unknown origin, liver failure (severity A and B on the Child-Pugh scale), pregnancy, lactation.

Caution. Severe electrolyte imbalance, endocrine and metabolic disorders, alcoholism, history of liver disease, arterial hypotension, severe acute infections, uncontrolled seizures, major surgery, trauma, childhood (efficacy and safety of use have not been established).

How to use: dosage and course of treatment

By mouth, taken at any time of the day, with or without food. The initial dose is 10 mg 1 time per day. The dose should be changed at intervals of at least 4 weeks. The maximum daily dose is 80 mg in 1 dose.

For primary hypercholesterolemia and combined (mixed) hyperlipidemia, 10 mg once a day is prescribed. The effect of treatment is manifested within 2 weeks, the maximum effect is observed within 4 weeks.

In homozygous familial hypercholesterolemia, 80 mg is prescribed once a day (lowering LDL by 18-45%).

Before starting therapy, the patient must be prescribed a standard hypocholesterolemic diet, which he must follow during treatment.

Pharmacological action

Lipid-lowering drug from the statin group. Selective competitive inhibitor of HMG-CoA reductase, an enzyme that converts 3-hydroxy-3-methylglutaryl coenzyme A to mevalonic acid, which is a precursor of sterols, including cholesterol.

TG and cholesterol in the liver are included in the composition of VLDL, enter the plasma and are transported to peripheral tissues. LDL is formed from VLDL during interaction with LDL receptors.

The drug reduces plasma cholesterol and lipoprotein levels by inhibiting HMG-CoA reductase, cholesterol synthesis in the liver and increasing the number of “liver” LDL receptors on the cell surface, which leads to increased uptake and catabolism of LDL.

Reduces the formation of LDL, causes a pronounced and persistent increase in the activity of LDL receptors. Reduces LDL levels in patients with homozygous familial hypercholesterolemia, which usually does not respond to lipid-lowering drugs.

Reduces total cholesterol by 30-46%, LDL – by 41-61%, apolipoprotein B – by 34-50% and TG – by 14-33%; causes an increase in the level of HDL-cholesterol (high density lipoprotein) and apolipoprotein A.

Taking the drug Lipitor dose-dependently reduces the level of LDL in patients with homozygous hereditary hypercholesterolemia, resistant to therapy with other lipid-lowering drugs.

Treatment with Lipitor significantly reduces the risk of ischemic complications (including the development of death from myocardial infarction) by 16%, the risk of re-hospitalization for angina pectoris accompanied by signs of myocardial ischemia – by 26%.

Atorvastatin is not carcinogenic or mutagenic.

Special instructions

Treatment may cause an increase in serum CPK, which should be taken into account in the differential diagnosis of retrosternal pain.

It is necessary to regularly monitor liver function indicators before starting treatment, 6 and 12 weeks after the start of the drug or after increasing the dose, and periodically during the entire period of use (until the condition of patients with transaminase levels exceeding normal is completely normalized). An increase in “liver” transaminases is observed mainly in the first 3 months of using the drug.

It is recommended to stop the drug or reduce the dose if the increase in AST and ALT values ​​is more than 3 times. The use of the drug should be temporarily discontinued with the development of clinical symptoms suggesting the presence of acute myopathy, or in the presence of factors predisposing to the development of acute renal failure against the background of rhabdomyolysis (severe infections, hypotension, traumatic surgery, trauma, metabolic, endocrine or severe electrolyte disturbances). Patients should be warned that they should immediately consult a doctor if unexplained pain or weakness in the muscles occurs, especially if they are accompanied by malaise or fever.

Women of reproductive age should use reliable methods of contraception.

Limited experience with 80 mg/day in children. Controlled studies in children have not been conducted, however, adverse reactions when using the drug in 8 children older than 9 years with familial homozygous hypercholesterolemia at a dose of up to 80 mg / day for 1 year were not detected.

Use in pregnancy and lactation

The drug is contraindicated in pregnancy and lactation.


Co-administration of cyclosporine, fibrates, erythromycin, clarithromycin, immunosuppressive, antifungal drugs (related to azoles) and nicotinamide with atorvastatin increases plasma concentrations of atorvastatin (and the risk of myopathy).

Antacids reduce concentration by 35% (the effect on LDL cholesterol does not change).

Simultaneous use of atorvastatin with protease inhibitors, known as inhibitors of cytochrome CYP3A4, is accompanied by an increase in plasma concentrations of the drug.

When digoxin is used in combination with atorvastatin at a dose of 80 mg/day, the concentration of digoxin increases by approximately 20%.

Increases the concentration by 20% (when administered with the drug at a dose of 80 mg / day) of oral contraceptives containing norethindrone and ethinyl estradiol.

The lipid-lowering effect of the combination with colestipol is superior to that of either drug alone.
