Precautions & Cautions
This medication can affect the bone marrow's ability to produce blood cells, which may lead to bleeding problems, infections, or anemia if blood cell counts become too low. If you have concerns, discuss them with your doctor. You may be more susceptible to infections, so it is crucial to practice good hygiene by washing your hands frequently and avoiding close contact with people who have infections, colds, or flu.
Be cautious, as you may experience easier bleeding. To minimize the risk of injury, use a soft toothbrush and an electric razor. If you encounter stomach upset, vomiting, diarrhea, or decreased appetite, consult your doctor, as there may be ways to alleviate these side effects.
To manage mouth sores, use a soft toothbrush or cotton swabs and rinse your mouth with a non-alcoholic mouthwash. If you have previously received daunorubicin, doxorubicin, epirubicin, idarubicin, or mitoxantrone, inform your doctor.
Long-term use of this medication (more than 1 year) has been associated with an increased risk of mouth cancer, which may occur during treatment or up to 6 years after the last dose. Your doctor will regularly examine your mouth while you are taking this medication. If you experience mouth pain, sores, or ulcers, contact your doctor immediately.
Before receiving any vaccinations, consult your doctor, as some vaccines may not be effective or may increase the risk of infection when used with this medication.
This medication may affect fertility, potentially leading to difficulty conceiving or fathering a child. Although fertility may return to normal, it is essential to discuss any concerns with your doctor.
Women may experience cessation of menstrual periods during treatment, which may or may not resume after treatment completion. Additionally, women treated with this medication may enter menopause at a younger age than usual. If you have questions or concerns, discuss them with your doctor.
This medication can harm an unborn baby. A pregnancy test will be conducted before initiating treatment to confirm that you are not pregnant. If you may become pregnant, use birth control while taking this medication and for 6 months after the last dose, unless otherwise instructed by your doctor. If you become pregnant, notify your doctor immediately.
If your partner may become pregnant, use birth control while taking this medication and for 6 months after the last dose. If your partner becomes pregnant, contact the doctor right away.
Overdose Information
Overdose Symptoms:
- Severe myelosuppression (very low white blood cell, red blood cell, and platelet counts)
- Severe mucositis
- Acute cardiac toxicity
What to Do:
There is no specific antidote for doxorubicin overdose. Management is supportive, including hospitalization, antibiotics for infection, platelet transfusions for bleeding, and symptomatic treatment for mucositis and cardiac toxicity. Call 1-800-222-1222 (Poison Control) or seek immediate medical attention.
Drug Interactions
Major Interactions
- Live vaccines (risk of severe infection)
- Strong CYP3A4 inhibitors (e.g., ketoconazole, clarithromycin, ritonavir) - may increase doxorubicin levels
- Strong CYP3A4 inducers (e.g., rifampin, carbamazepine, phenytoin) - may decrease doxorubicin levels
- Other myelosuppressive agents (additive myelosuppression)
- Cardiotoxic agents (e.g., trastuzumab, cyclophosphamide, 5-FU) - increased risk of cardiotoxicity
Moderate Interactions
- Warfarin (potential for increased INR/bleeding)
- Phenytoin (potential for decreased phenytoin levels)
- Cimetidine (may increase doxorubicin levels)
- Paclitaxel (may increase doxorubicin levels when given before doxorubicin)
Monitoring
Baseline Monitoring
Rationale: To assess baseline bone marrow function and identify pre-existing cytopenias.
Timing: Prior to initiation of therapy.
Rationale: To assess hepatic function for dose adjustment.
Timing: Prior to initiation of therapy.
Rationale: To assess renal function.
Timing: Prior to initiation of therapy.
Rationale: To establish baseline cardiac ejection fraction due to risk of cardiotoxicity.
Timing: Prior to initiation of therapy.
Rationale: To assess for mucositis risk.
Timing: Prior to initiation of therapy.
Routine Monitoring
Frequency: Prior to each dose and as clinically indicated.
Target: ANC ≥ 1,000-1,500 cells/mm³, Platelets ≥ 75,000-100,000 cells/mm³ (varies by protocol)
Action Threshold: Hold or reduce dose for significant myelosuppression (e.g., ANC < 1,000 cells/mm³ or platelets < 50,000 cells/mm³).
Frequency: Prior to each dose.
Target: Bilirubin < 1.2 mg/dL, AST/ALT within normal limits.
Action Threshold: Adjust dose for elevated bilirubin (>1.2 mg/dL) or AST (>2x ULN).
Frequency: Periodically, especially with cumulative doses exceeding 400 mg/m² or if cardiac symptoms develop.
Target: LVEF within normal limits or no significant decline from baseline.
Action Threshold: Discontinue if LVEF declines significantly (e.g., >10-20% absolute drop) or falls below lower limit of normal.
Frequency: Prior to each dose and throughout treatment.
Target: No signs of Hand-Foot Syndrome (Palmar-Plantar Erythrodysesthesia - PPE).
Action Threshold: Hold or reduce dose for Grade 2 or higher PPE.
Frequency: Prior to each dose and throughout treatment.
Target: No signs of mucositis.
Action Threshold: Hold or reduce dose for Grade 2 or higher mucositis.
Symptom Monitoring
- Fever, chills, signs of infection (due to myelosuppression)
- Unusual bleeding or bruising
- Fatigue, shortness of breath, swelling in ankles/legs (signs of cardiotoxicity)
- Redness, swelling, pain, blistering on palms of hands or soles of feet (Hand-Foot Syndrome)
- Sore mouth, mouth sores, difficulty swallowing (mucositis)
- Nausea, vomiting, diarrhea
- Hair loss
- Infusion-related reactions (flushing, shortness of breath, chest pain, back pain, fever, chills, hypotension, tachycardia)
Special Patient Groups
Pregnancy
Contraindicated in pregnancy. Doxorubicin liposomal can cause fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to the fetus. Advise females of reproductive potential to use effective contraception during treatment and for 6 months after the last dose. Advise males with female partners of reproductive potential to use effective contraception during treatment and for 6 months after the last dose.
Trimester-Specific Risks:
Lactation
Breastfeeding is contraindicated during treatment and for 10 days after the last dose. It is unknown if doxorubicin liposomal is excreted in human milk, but due to the potential for serious adverse reactions in breastfed infants, advise women not to breastfeed.
Pediatric Use
Safety and effectiveness have not been established in pediatric patients. Use is generally not recommended.
Geriatric Use
No overall differences in safety or effectiveness were observed between elderly patients and younger adult patients. However, greater sensitivity of some older individuals cannot be ruled out. Close monitoring for adverse effects is recommended.
Clinical Information
Clinical Pearls
- Always administer doxorubicin liposomal slowly (over 30-60 minutes) to minimize infusion-related reactions. Pre-medication (antihistamines, corticosteroids) may be considered for patients with prior infusion reactions.
- The liposomal formulation has a different toxicity profile than conventional doxorubicin, with reduced cardiotoxicity and myelosuppression but increased incidence of Hand-Foot Syndrome (PPE) and mucositis.
- Cumulative lifetime dose of doxorubicin liposomal should be carefully monitored, especially in patients with pre-existing cardiac conditions or prior anthracycline exposure, due to the risk of cardiotoxicity.
- Manage Hand-Foot Syndrome proactively with moisturizers, avoiding hot water, and wearing comfortable shoes. Dose modifications may be necessary for severe PPE.
- Oral cryotherapy (ice chips) during infusion may help reduce the incidence and severity of mucositis.
- Extravasation is rare with the liposomal formulation due to its encapsulation, but still requires careful administration. If extravasation occurs, follow institutional guidelines; cold compresses are generally recommended.
Alternative Therapies
- Paclitaxel (for ovarian cancer)
- Topotecan (for ovarian cancer)
- Bortezomib (for multiple myeloma)
- Lenalidomide (for multiple myeloma)
- Pomalidomide (for multiple myeloma)
- Other cytotoxic agents depending on specific cancer type and stage.
