- dizziness
- fainting
- unusual bruising or bleeding
- fever
- chills
- diarrhea
- sore throat
- muscle aches
- shortness of breath

Arrhythmia
Major:
interferon alfa-2b
Interferon alfa-2b has a major potential interaction with Arrhythmia.
Hypertension, arrhythmias, angina, myocardial infarction, cardiomyopathy, and congestive heart failure have been reported during interferon therapy. Therapy with interferons should be administered with caution in patients with compromised cardiac function.
Autoimmune Disorders
Major:
interferon alfa-2b
Interferon alfa-2b has a major potential interaction with Autoimmune Disorders.
Antiviral interferons may exacerbate autoimmune disorders such as myositis, thyroiditis, systemic lupus erythematosus, rheumatoid arthritis, psoriasis, or autoimmune hepatitis. Therapy should be avoided or administered with extreme caution in patients with autoimmune disorders.
Bleeding Disorder
Major:
melphalan
Melphalan has a major potential interaction with Bleeding Disorder.
Bone marrow suppression is the most significant toxicity associated with melphalan in most patients. The following tests should be performed at the start of therapy and prior to each subsequent dose of melphalan: platelet count, hemoglobin, white blood cell count, and differential. Thrombocytopenia and/or leukopenia are indications to withhold further therapy until the blood counts have sufficiently recovered. Frequent blood counts are essential to determine optimal dosage and to avoid toxicity. Dose adjustment on the basis of blood counts at the nadir and day of treatment should be considered.
Bone Marrow Depression/Low Blood Counts
Major:
melphalan
Melphalan has a major potential interaction with Bone Marrow Depression/Low Blood Counts.
Bone marrow suppression is the most significant toxicity associated with melphalan in most patients. The following tests should be performed at the start of therapy and prior to each subsequent dose of melphalan: platelet count, hemoglobin, white blood cell count, and differential. Thrombocytopenia and/or leukopenia are indications to withhold further therapy until the blood counts have sufficiently recovered. Frequent blood counts are essential to determine optimal dosage and to avoid toxicity. Dose adjustment on the basis of blood counts at the nadir and day of treatment should be considered.
Moderate:
interferon alfa-2b
Interferon alfa-2b has a moderate potential interaction with Bone Marrow Depression/Low Blood Counts.
Interferons (alfa and gamma) induce a dose-dependent, generally mild, myelosuppression. Leukopenia is the primary manifestation. Thrombocytopenia and anemia occur less frequently. Therapy with interferons (alfa and gamma) should be administered cautiously to patients with bone marrow suppression. Clinical monitoring of hematopoietic function is recommended.
Cardiovascular Conditions and Disorders
Major:
interferon alfa-2b
Interferon alfa-2b has a major potential interaction with Cardiovascular Conditions and Disorders.

Depression
Major:
interferon alfa-2b
Interferon alfa-2b has a major potential interaction with Depression.
Interferons (alfa or beta) can induce depression and suicidal behavior. Suicidal attempts and suicides have been reported. Therapy with interferons (alfa or beta) should be administered cautiously to patients with or predisposed to mental depression. Clinical monitoring of psychological status is recommended.
Diabetes Mellitus
Moderate:
interferon alfa-2b
Interferon alfa-2b has a moderate potential interaction with Diabetes Mellitus.
Flu-like symptoms frequently associated with interferon-alfa therapy can precipitate ketoacidosis in diabetic patients. Therapy with interferon alfa should be administered cautiously in patients with diabetes mellitus. Clinical monitoring of blood glucose concentrations and anti-diabetic therapy is recommended.
Fever
Major:
melphalan
Melphalan has a major potential interaction with Fever.
Bone marrow suppression is the most significant toxicity associated with melphalan in most patients. The following tests should be performed at the start of therapy and prior to each subsequent dose of melphalan: platelet count, hemoglobin, white blood cell count, and differential. Thrombocytopenia and/or leukopenia are indications to withhold further therapy until the blood counts have sufficiently recovered. Frequent blood counts are essential to determine optimal dosage and to avoid toxicity. Dose adjustment on the basis of blood counts at the nadir and day of treatment should be considered.
Heart Failure
Major:
interferon alfa-2b
Interferon alfa-2b has a major potential interaction with Heart Failure.
Hypertension, arrhythmias, angina, myocardial infarction, cardiomyopathy, and congestive heart failure have been reported during interferon therapy. Therapy with interferons should be administered with caution in patients with compromised cardiac function.
Hyperthyroidism
Major:
interferon alfa-2b
Interferon alfa-2b has a major potential interaction with Hyperthyroidism.
Thyroid abnormalities, hypothyroidism or hyperthyroidism, have been reported in patients administered interferons. Therapy with interferons should be administered cautiously to patients with thyroid dysfunction. If thyroid control cannot be maintained within normal limits with medication, interferon-alfa should be discontinued. Clinical monitoring of thyroid function is recommended.
Infection
Major:
melphalan
Melphalan has a major potential interaction with Infection.
Because of their cytotoxic effects on rapidly proliferating tissues, antineoplastic agents frequently can, to varying extent, induce myelosuppression. The use of these drugs may be contraindicated in patients with known infectious diseases. All patients should be instructed to immediately report any signs or symptoms suggesting infection such as fever, sore throat, or local infection during antineoplastic therapy. Close clinical monitoring of hematopoietic function is recommended.
Ischemic Heart Disease
Major:

Any patient developing liver function abnormalities during treatment should be monitored closely and treatment should be discontinued if appropriate. Interferon-alfa is contraindicated in patients with autoimmune hepatitis and decompensated liver disease.
Parkinsonism
Major:

Proteinuria (rare), not associated with a decrease in serum protein, is the most common renal toxicity observed with interferon- alfa therapy. Increased BUN and serum creatinine levels, hematuria, acute renal failure and nephrotic syndrome have also been reported. Therapy with interferon alfa should be administered cautiously to patients with severe renal dysfunction. Renal function should be evaluated in all patients before initiation of interferon- alfa therapy. In addition, patients with any degree of renal impairment should be carefully monitored for laboratory abnormalities and decreased creatinine clearance. A reduced dose of medication is recommended in patients with low CrCl (less than 50 mL/min - 30 mL/min).
Moderate:

Melphalan has a moderate potential interaction with Renal Dysfunction.
The incidence of myelosuppression, particularly during IV administration of melphalan, is increased in patients with a BUN > 30 mg/dl. Therapy with melphalan should be administered cautiously and initiated at a reduced dosage in patients with moderate to severe renal impairment. Clinical monitoring of renal function is recommended.
