Before Using This Medicine
It is essential to inform your doctor about the following:
Any allergies you have, including allergies to this medication, its components, or other substances, such as foods or drugs. Be sure to describe the symptoms you experienced.
If you have liver disease or elevated liver enzymes.
If you are currently taking any of the following medications: Cyclosporine, gemfibrozil, glecaprevir plus pibrentasvir, letermovir, or tipranavir plus ritonavir.
If you are pregnant or think you might be pregnant. Note that this medication is not recommended during pregnancy.
* If you are breastfeeding. You should not breastfeed while taking this medication.
This list is not exhaustive, and it is crucial to discuss all your medications (including prescription, over-the-counter, natural products, and vitamins) and health issues with your doctor and pharmacist. They will help determine if it is safe to take this medication with your other drugs and health conditions. Never start, stop, or adjust the dosage of any medication without first consulting your doctor.
Precautions & Cautions
If you consume grapefruit juice or eat grapefruit frequently, discuss this with your doctor. Limit your alcohol intake to no more than 2 drinks per day, as excessive alcohol consumption may increase your risk of developing liver disease.
Be aware that this medication may cause muscle pain, tenderness, or weakness, which can be severe and potentially lead to kidney problems. In rare cases, this has resulted in fatalities. The risk of these adverse effects may be higher if you have pre-existing thyroid problems, kidney problems, infections, low blood pressure, or a history of seizures. Additionally, the risk may be increased if you are taking certain other medications or are dehydrated. Older adults, particularly those aged 65 and above, may also have a higher risk of experiencing these side effects. If you have any concerns or questions, consult your doctor.
As you age, your sensitivity to this medication may increase. If you are 65 or older, use this drug with caution, as you may be more susceptible to side effects.
This medication may pose a risk to an unborn baby. If you are of childbearing potential, it is essential to use birth control while taking this drug. If you become pregnant, notify your doctor immediately.
Overdose Information
Overdose Symptoms:
- No specific symptoms of overdose have been reported. The most likely adverse effects would be exaggerated side effects such as muscle pain or liver enzyme elevations.
What to Do:
There is no specific antidote for atorvastatin overdose. In the event of an overdose, the patient should be treated symptomatically, and supportive measures instituted as required. Due to extensive protein binding, hemodialysis is not expected to significantly enhance atorvastatin clearance. Call 1-800-222-1222 (Poison Control).
Drug Interactions
Contraindicated Interactions
- Cyclosporine
- Gemfibrozil (increased risk of myopathy/rhabdomyolysis)
- Tipranavir/Ritonavir (increased atorvastatin exposure)
Major Interactions
- Strong CYP3A4 inhibitors (e.g., Itraconazole, Ketoconazole, Clarithromycin, Telithromycin, Voriconazole, HIV protease inhibitors like Lopinavir/Ritonavir, Saquinavir/Ritonavir, Darunavir/Ritonavir, Fosamprenavir/Ritonavir, Nelfinavir, Indinavir, Atazanavir/Ritonavir, Delavirdine, Cobicistat-containing products) - significantly increase atorvastatin exposure and risk of myopathy.
- Other fibrates (e.g., Fenofibrate) - increased risk of myopathy/rhabdomyolysis.
- Niacin (lipid-lowering doses âĨ1 g/day) - increased risk of myopathy/rhabdomyolysis.
- Colchicine (in patients with renal or hepatic impairment) - increased risk of myopathy/rhabdomyolysis.
Moderate Interactions
- Moderate CYP3A4 inhibitors (e.g., Erythromycin, Diltiazem, Verapamil, Fluconazole, Amiodarone, Amlodipine, Grapefruit juice (large quantities >1.2 L/day)) - may increase atorvastatin exposure.
- Rifampin (CYP3A4 inducer) - may decrease atorvastatin concentrations (administer simultaneously).
- Digoxin - may increase digoxin concentrations.
- Oral contraceptives (norethindrone and ethinyl estradiol) - may increase concentrations of oral contraceptive components.
Minor Interactions
- Antacids (magnesium-aluminum hydroxide) - decrease atorvastatin plasma concentrations (no effect on LDL-C reduction).
- Warfarin - slight decrease in prothrombin time (monitor INR).
Monitoring
Baseline Monitoring
Rationale: To establish baseline lipid levels and assess the need for therapy.
Timing: Prior to initiation of therapy.
Rationale: To establish baseline liver enzyme levels and rule out active liver disease, as statins can cause transaminase elevations.
Timing: Prior to initiation of therapy.
Rationale: To establish baseline levels in patients with predisposing factors for myopathy (e.g., renal impairment, hypothyroidism, history of muscle toxicity with other lipid-lowering agents, genetic muscle disorders, alcoholism).
Timing: Prior to initiation of therapy, if indicated.
Routine Monitoring
Frequency: 4-12 weeks after initiation or dose titration, then every 3-12 months thereafter.
Target: LDL-C reduction based on individual risk assessment and guideline recommendations (e.g., >50% reduction for high-intensity statin).
Action Threshold: If LDL-C goal not met, consider dose titration or combination therapy. If lipid levels are excessively low, consider dose reduction.
Frequency: As clinically indicated (e.g., if symptoms suggestive of liver injury occur). Routine periodic monitoring is no longer recommended by FDA unless clinically indicated.
Target: ALT/AST < 3 times upper limit of normal (ULN).
Action Threshold: If persistent elevations >3 times ULN occur, discontinue atorvastatin. If elevations are <3 times ULN but persistent, consider dose reduction or discontinuation.
Frequency: Only if muscle symptoms (e.g., pain, tenderness, weakness) develop.
Target: CK < 10 times ULN.
Action Threshold: If CK levels are significantly elevated (>10 times ULN) or if myopathy/rhabdomyolysis is diagnosed or suspected, discontinue atorvastatin immediately. If muscle symptoms are severe or debilitating, consider discontinuing even if CK is not significantly elevated.
Symptom Monitoring
- Unexplained muscle pain, tenderness, or weakness (especially if accompanied by malaise or fever)
- Dark urine (suggestive of myoglobinuria)
- Yellowing of skin or eyes (jaundice)
- Unusual fatigue or weakness
- Loss of appetite
- Upper right abdominal pain
Special Patient Groups
Pregnancy
Atorvastatin is contraindicated in pregnancy. Statins may cause fetal harm when administered to pregnant women. Cholesterol and other products of cholesterol biosynthesis are essential for fetal development, including synthesis of steroids and cell membranes. The risk of therapy should be weighed against the potential benefits.
Trimester-Specific Risks:
Lactation
Atorvastatin is contraindicated during breastfeeding. It is unknown whether atorvastatin or its metabolites are excreted in human milk. Because of the potential for serious adverse reactions in nursing infants, women taking atorvastatin should not breastfeed.
Pediatric Use
Atorvastatin is approved for use in pediatric patients aged 10 years and older with heterozygous familial hypercholesterolemia (HeFH) or homozygous familial hypercholesterolemia (HoFH). Dosing should be individualized based on the patient's lipid levels and response to therapy. Safety and efficacy have not been established in patients younger than 10 years of age.
Geriatric Use
No overall differences in safety or effectiveness have been observed between geriatric (âĨ65 years) and younger patients. However, greater sensitivity of some older individuals cannot be ruled out. Use with caution and monitor for adverse effects, particularly muscle-related symptoms.
Clinical Information
Clinical Pearls
- Atorvastatin is a high-intensity statin at doses of 40-80 mg and a moderate-intensity statin at doses of 10-20 mg, making 10mg a common starting dose for many patients.
- Unlike some other statins, atorvastatin can be taken at any time of day, as its long half-life ensures consistent efficacy.
- Patients should be educated on the importance of reporting any unexplained muscle pain, tenderness, or weakness immediately, as this could be a sign of myopathy or rhabdomyolysis.
- Liver function tests are recommended at baseline, but routine periodic monitoring is no longer universally recommended unless clinically indicated, due to the low incidence of clinically significant liver injury.
- Grapefruit juice (especially large quantities) should be avoided due to its potential to inhibit CYP3A4 and increase atorvastatin exposure.
