If you become pregnant, notify your doctor immediately to discuss the best course of action.
Overdose Information
Overdose Symptoms:
- No specific symptoms of overdose have been reported with lovastatin. The most likely symptoms would be an exaggeration of known side effects, such as muscle pain or liver enzyme elevations.
What to Do:
In case of suspected overdose, contact a poison control center immediately (e.g., 1-800-222-1222 in the US) or seek emergency medical attention. Treatment is generally supportive, as lovastatin is highly protein-bound and not significantly removed by hemodialysis.
Drug Interactions
Contraindicated Interactions
- Strong CYP3A4 inhibitors (e.g., itraconazole, ketoconazole, posaconazole, voriconazole, erythromycin, clarithromycin, telithromycin, HIV protease inhibitors, nefazodone, cobicistat)
- Gemfibrozil
- Cyclosporine
- Danazol (high doses)
- Amiodarone (doses > 20 mg lovastatin)
- Verapamil (doses > 20 mg lovastatin)
- Diltiazem (doses > 20 mg lovastatin)
- Grapefruit juice (large quantities)
Major Interactions
- Other fibrates (e.g., fenofibrate) - increased risk of myopathy/rhabdomyolysis
- Niacin (lipid-lowering doses âĨ1 g/day) - increased risk of myopathy/rhabdomyolysis
- Colchicine - increased risk of myopathy/rhabdomyolysis
- Warfarin - enhanced anticoagulant effect (monitor INR)
- Ranolazine - increased lovastatin exposure
- Daptomycin - increased risk of myopathy/rhabdomyolysis (consider temporary discontinuation of statin)
Moderate Interactions
- Moderate CYP3A4 inhibitors (e.g., fluconazole, verapamil, diltiazem, amiodarone, dronedarone, ranolazine) - dose limitation for lovastatin
- Amlodipine - dose limitation for lovastatin
- Ticagrelor - increased lovastatin exposure
- Oral contraceptives - increased estrogen levels
Minor Interactions
- Digoxin - slight increase in digoxin levels (monitor)
- Antacids - may decrease lovastatin absorption (separate administration)
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 pre-existing liver disease, as statins can cause transaminase elevations.
Timing: Prior to initiation of therapy.
Rationale: To establish baseline levels, especially in patients with predisposing factors for myopathy (e.g., renal impairment, hypothyroidism, history of muscle toxicity with other lipid-lowering agents).
Timing: Prior to initiation of therapy (optional, but recommended in high-risk patients).
Routine Monitoring
Frequency: 4-6 weeks after initiation or dose titration, then every 6-12 months or as clinically indicated.
Target: LDL-C reduction based on individual risk assessment and guideline recommendations (e.g., <100 mg/dL, <70 mg/dL).
Action Threshold: Failure to achieve target LDL-C, consider dose adjustment or alternative therapy. If lipid levels are not responding as expected, assess adherence and diet.
Frequency: At baseline, then as clinically indicated. Routine periodic monitoring is no longer universally recommended unless clinically indicated (e.g., symptoms suggestive of liver injury).
Target: Within normal limits.
Action Threshold: If persistent elevations >3 times the upper limit of normal (ULN) occur, discontinue lovastatin. If elevations are 1-3 times ULN, monitor closely or consider dose reduction/discontinuation.
Frequency: Not routinely recommended unless muscle symptoms (pain, tenderness, weakness) develop.
Target: Within normal limits.
Action Threshold: If CK levels are significantly elevated (>10 times ULN) or if muscle symptoms are severe, discontinue lovastatin immediately. If CK elevations are 5-10 times ULN, monitor closely and consider discontinuation.
Symptom Monitoring
- Unexplained muscle pain, tenderness, or weakness (especially if accompanied by malaise or fever)
- Dark-colored urine (tea-colored)
- Yellowing of the skin or eyes (jaundice)
- Unusual fatigue or weakness
- Loss of appetite
- Upper right abdominal pain
- Nausea or vomiting
Special Patient Groups
Pregnancy
Lovastatin is contraindicated in pregnancy (Pregnancy Category X). Cholesterol and its derivatives are essential for fetal development. Statins may cause fetal harm by decreasing the synthesis of cholesterol and possibly other biologically active substances derived from cholesterol. There are reports of congenital anomalies following in utero exposure to statins.
Trimester-Specific Risks:
Lactation
Lovastatin is contraindicated during breastfeeding. It is unknown if lovastatin is excreted in human milk, but a small amount of another statin (pravastatin) has been shown to pass into breast milk. Because of the potential for serious adverse reactions in nursing infants, women taking lovastatin should not breastfeed.
Pediatric Use
Use is generally limited to adolescent patients (10-17 years) with heterozygous familial hypercholesterolemia, after failure of diet therapy. Dosing is lower than adults, and careful monitoring is required. Not recommended for children under 10 years of age due to insufficient data on long-term safety and efficacy.
Geriatric Use
No specific dose adjustment is required based on age alone. However, elderly patients may be at increased risk for myopathy and should be monitored closely for adverse effects. Consider starting at lower doses and titrating cautiously.
Clinical Information
Clinical Pearls
- Always advise patients to take lovastatin with the evening meal for optimal absorption and efficacy.
- Emphasize the importance of dietary and lifestyle modifications (low-cholesterol diet, exercise) as they are foundational to lipid management.
- Strongly caution patients against consuming grapefruit or grapefruit juice due to the significant interaction with CYP3A4, which can lead to increased lovastatin levels and higher risk of myopathy.
- Educate patients on the signs and symptoms of myopathy/rhabdomyolysis (muscle pain, weakness, dark urine) and liver injury (jaundice, fatigue, abdominal pain) and instruct them to report these immediately.
- Lovastatin is a prodrug; its active form is lovastatin acid.
- Consider genetic testing for CYP3A4 variants in patients with unexpected responses or adverse effects, although not routinely recommended.
- For patients on cyclosporine, danazol, gemfibrozil, or strong CYP3A4 inhibitors, lovastatin is contraindicated. For other interacting drugs (e.g., amiodarone, verapamil, diltiazem), specific dose limitations apply.
