If you are pregnant or think you might be pregnant, as this medication may harm an unborn baby. Your doctor will help you weigh the benefits and risks of taking this medication during pregnancy.
If you are breastfeeding, as you should not breastfeed while taking this medication.
Additionally, it is crucial to discuss all your medications, including prescription and over-the-counter drugs, natural products, and vitamins, with your doctor and pharmacist. This includes:
All prescription medications you are currently taking
Over-the-counter medications, such as pain relievers or antihistamines
Natural products, including herbal supplements or vitamins
* Any health problems you have, as they may interact with the medication
Do not start, stop, or change the dose of any medication without first consulting your doctor to ensure your safety. This list is not exhaustive, and your doctor and pharmacist need to be aware of all your medications and health conditions to provide the best possible care.
Precautions & Cautions
To maximize the benefits of this medication, it is crucial to follow the diet and exercise plan recommended by your doctor. Adhering to the prescribed dosage is also vital, as taking more than the recommended amount may increase the risk of severe side effects.
If you have diabetes, it is essential to closely monitor your blood sugar levels while taking this medication. When taking cholestyramine or colestipol, ensure that you take them at least 4 hours before or 1 hour after this drug to avoid any potential interactions.
To minimize the risk of liver disease, it is recommended that you limit your alcohol consumption to no more than 2 drinks per day. Excessive alcohol consumption may increase your risk of liver disease.
If you are 65 years or older, use this medication with caution, as you may be more susceptible to side effects. Additionally, if you are of childbearing age, you may need to use birth control to prevent pregnancy while taking this medication. It is essential to discuss this with your doctor to determine the best course of action.
Overdose Information
Overdose Symptoms:
- No specific symptoms reported for pravastatin overdose in humans. The most likely adverse effects would be an exaggeration of known side effects, such as muscle pain or liver enzyme elevations.
What to Do:
There is no specific antidote. Treatment should be symptomatic and supportive. Monitor liver function and CK levels. Contact a poison control center immediately (e.g., 1-800-222-1222 in the US).
Drug Interactions
Contraindicated Interactions
- Gemfibrozil (increased risk of myopathy/rhabdomyolysis)
- Cyclosporine (high doses of pravastatin, increased risk of myopathy/rhabdomyolysis)
Major Interactions
- Fibrates (e.g., fenofibrate): Increased risk of myopathy/rhabdomyolysis. Use with caution, consider lower pravastatin dose.
- Niacin (lipid-lowering doses β₯1 g/day): Increased risk of myopathy/rhabdomyolysis. Use with caution.
- Colchicine: Increased risk of myopathy/rhabdomyolysis. Use with caution.
- Cyclosporine: Increased pravastatin exposure. Limit pravastatin dose to 20 mg/day.
Moderate Interactions
- Clarithromycin, Erythromycin: May slightly increase pravastatin levels (less significant than with other statins). Monitor for myopathy.
- Diltiazem, Verapamil: May slightly increase pravastatin levels. Monitor for myopathy.
- Warfarin: May slightly increase INR. Monitor INR upon initiation or discontinuation of pravastatin.
Minor Interactions
- Antacids (magnesium/aluminum hydroxide): Decreased pravastatin absorption if taken simultaneously. Administer pravastatin 1 hour before antacids.
- Cholestyramine/Colestipol: Decreased pravastatin absorption. Administer pravastatin 1 hour before or 4 hours after bile acid sequestrants.
Monitoring
Baseline Monitoring
Rationale: To establish baseline lipid levels and assess treatment efficacy.
Timing: Before initiating therapy
Rationale: To establish baseline liver enzyme levels and monitor for drug-induced hepatotoxicity.
Timing: Before initiating therapy
Rationale: To establish baseline CK levels, especially in patients at increased risk for myopathy (e.g., history of muscle disorders, hypothyroidism, renal impairment, concomitant medications).
Timing: Before initiating therapy (if indicated)
Routine Monitoring
Frequency: 4-12 weeks after initiation or dose adjustment, then every 3-12 months or as clinically indicated.
Target: LDL-C reduction based on risk assessment and guideline recommendations (e.g., >50% reduction for high-intensity, 30-49% for moderate-intensity).
Action Threshold: Failure to achieve target LDL-C, or if lipid levels worsen, consider dose adjustment or alternative therapy.
Frequency: Periodically, or if symptoms suggestive of liver injury occur. Routine monitoring is no longer universally recommended unless clinically indicated.
Target: Within normal limits.
Action Threshold: Persistent elevations >3 times the upper limit of normal (ULN); discontinue pravastatin.
Frequency: Only if muscle symptoms (pain, tenderness, weakness) develop.
Target: Within normal limits.
Action Threshold: CK >10 times ULN, or if muscle symptoms are severe or accompanied by dark urine; discontinue pravastatin immediately. If CK is 5-10 times ULN, monitor closely and consider discontinuation.
Symptom Monitoring
- Unexplained muscle pain, tenderness, or weakness (myalgia, myopathy)
- Dark urine (rhabdomyolysis)
- Unusual fatigue or weakness
- Loss of appetite
- Upper abdominal pain
- Nausea, vomiting
- Yellowing of skin or eyes (jaundice)
Special Patient Groups
Pregnancy
Contraindicated. Statins can cause fetal harm when administered to pregnant women. Cholesterol and its derivatives are essential for fetal development.
Trimester-Specific Risks:
Lactation
Contraindicated. Pravastatin is excreted into breast milk. Due to the potential for serious adverse reactions in nursing infants and the disruption of lipid metabolism, breastfeeding is not recommended.
Pediatric Use
Approved for use in children aged 8 years and older with heterozygous familial hypercholesterolemia (HeFH). Dosing is age-dependent. Safety and efficacy in children younger than 8 years have not been established.
Geriatric Use
No overall differences in safety or effectiveness have been observed between elderly and younger patients. However, elderly patients may be at increased risk for myopathy, and renal function should be considered.
Clinical Information
Clinical Pearls
- Pravastatin is a hydrophilic statin, which may contribute to its lower potential for drug-drug interactions via CYP450 enzymes compared to lipophilic statins (e.g., simvastatin, atorvastatin).
- It is primarily eliminated via renal and biliary excretion, making it a preferred statin in patients with significant hepatic impairment (though still contraindicated in active liver disease).
- While less prone to CYP interactions, caution is still warranted with cyclosporine, fibrates, and high-dose niacin due to increased risk of myopathy.
- Administering pravastatin at bedtime is generally recommended as cholesterol synthesis is highest at night, but it can be taken at any time of day.
- Patients should be advised to report any unexplained muscle pain, tenderness, or weakness immediately.
Alternative Therapies
- Other HMG-CoA reductase inhibitors (statins): Atorvastatin, Rosuvastatin, Simvastatin, Lovastatin, Fluvastatin, Pitavastatin
- PCSK9 inhibitors: Alirocumab, Evolocumab
- Cholesterol absorption inhibitors: Ezetimibe
- Bile acid sequestrants: Cholestyramine, Colestipol, Colesevelam
- Fibrates: Fenofibrate, Gemfibrozil
- Niacin (nicotinic acid)
- Adenosine triphosphate-citrate lyase (ACL) inhibitors: Bempedoic acid
- Selective peroxisome proliferator-activated receptor alpha (PPARΞ±) modulators: Pemafibrate (not FDA approved in US)
- Omega-3 fatty acid ethyl esters
