27 potential interactions Applies to: 24 conditions, including Heart Failure, Seizures, Hypokalemia, Hypotension, and Anemia.
Acidosis
Moderate:
Flavalta
The EPINEPHrine in Flavalta has a moderate potential interaction with Acidosis.
Acidosis, hypoxia, and hypercapnia may reduce the effectiveness of sympathomimetic amines in raising blood pressure. These conditions should be corrected before initiating therapy with sympathomimetic amines, if possible. Monitoring the patients acid-base balance, carbon dioxide levels, and oxygen saturation is recommended.
Anemia
Moderate:
methyldopa
Methyldopa has a moderate potential interaction with Anemia.
Hemolytic anemia has occurred rarely during therapy with methyldopa and may be associated with a (+) direct Coombs. Therapy with methyldopa should be administered cautiously to patients with anemia or a predisposition to hemolytic syndromes. Clinical monitoring of hematopoietic function, including a baseline hematological profile, is recommended. If Coombs- positive hemolytic anemia occurs, the cause may be methyldopa and the drug should be discontinued
Bleeding Disorder
Moderate:
methyldopa
Methyldopa has a moderate potential interaction with Bleeding Disorder.
Hemolytic anemia has occurred rarely during therapy with methyldopa and may be associated with a (+) direct Coombs. Therapy with methyldopa should be administered cautiously to patients with anemia or a predisposition to hemolytic syndromes. Clinical monitoring of hematopoietic function, including a baseline hematological profile, is recommended.

Cardiovascular Conditions and Disorders
Major:
Flavalta
The EPINEPHrine in Flavalta has a major potential interaction with Cardiovascular Conditions and Disorders.
Sympathomimetic agents may cause adverse cardiovascular effects, particularly when used in high dosages and/or in susceptible patients. In cardiac tissues, these agents may produce positive chronotropic and inotropic effects via stimulation of beta- 1 adrenergic receptors. Cardiac output, oxygen consumption, and the work of the heart may be increased. In the peripheral vasculature, vasoconstriction may occur via stimulation of alpha-1 adrenergic receptors. Palpitations, tachycardia, arrhythmia, hypertension, reflex bradycardia, coronary occlusion, cerebral vasculitis, myocardial infarction, cardiac arrest, and death have been reported. Some of these agents, particularly ephedra alkaloids (ephedrine, ma huang, phenylpropanolamine), may also predispose patients to hemorrhagic and ischemic stroke. Therapy with sympathomimetic agents should generally be avoided or administered cautiously in patients with sensitivity to sympathomimetic amines, hyperthyroidism, or underlying cardiovascular or cerebrovascular disorders. These agents should not be used in patients with severe coronary artery disease or severe/uncontrolled hypertension.
Dehydration
Major:
Flavalta
The EPINEPHrine in Flavalta has a major potential interaction with Dehydration.
The use of sympathomimetic amines has been infrequently associated with significant hypotension especially in dehydrated patients secondary to the drug's beta-2 mediated vasodilation. Hypovolemia should be corrected, if possible, before administering sympathomimetic amines. Blood pressure and ECG should be monitored at regular intervals. Monitoring of cardiac output and pulmonary wedge pressure may also be desired.
Diabetes Mellitus
Moderate:
Flavalta
The EPINEPHrine in Flavalta has a moderate potential interaction with Diabetes Mellitus.
Sympathomimetic agents may cause increases in blood glucose concentrations. These effects are usually transient and slight but may be significant with dosages higher than those normally recommended. Therapy with sympathomimetic agents should be administered cautiously in patients with diabetes mellitus. Closer monitoring of blood glucose concentrations may be appropriate.
Fluid Retention
Moderate:
methyldopa
Methyldopa has a moderate potential interaction with Fluid Retention.
Methyldopa may cause edema or weight gain associated with sodium retention. Therapy with methyldopa should be administered cautiously in patients adversely affected by sodium and water retention.

Alternative therapy should be considered unless these conditions are secondary to cardiac arrhythmia.
Liver Disease
Major:
Flavalta
The lidocaine in Flavalta has a major potential interaction with Liver Disease.
Lidocaine is rapidly and extensively metabolized by the liver. Less than 10% is eliminated unchanged in the urine. Several inactive and two active forms (MEGX and GX) have been identified. MEGX and GX exhibit antiarrhythmic and convulsant properties. GX accumulates during prolonged intravenous lidocaine infusion. The pharmacokinetic disposition of lidocaine is altered by changes in hepatic function, including hepatic blood flow. Therapy with lidocaine should be administered cautiously and dosing modifications for repeated or loading and maintenance doses may be necessary. Clinical monitoring of cardiac (continuous ECG) is required and serum metabolite concentrations and monitoring hepatic function are recommended.
Major:
methyldopa
Methyldopa has a major potential interaction with Liver Disease.
The use of methyldopa is contraindicated in patients with active liver disease, such as active hepatitis or active cirrhosis, and in patients with previous methyldopa- associated liver disorders. Hepatotoxicity is an uncommon but toxic effect of methyldopa. Therapy with methyldopa should be administered cautiously in patients with a history of or predisposition to liver disease.
Magnesium Imbalance
Moderate:
Flavalta
The lidocaine in Flavalta has a moderate potential interaction with Magnesium Imbalance.
Electrolyte imbalance can alter the therapeutic effectiveness of antiarrhythmic agents. Hypokalemia and hypomagnesemia can reduce the effectiveness of antiarrhythmic agents.

These agents should not be used in patients with severe coronary artery disease or severe/uncontrolled hypertension.
Moderate:
methyldopa
Methyldopa has a moderate potential interaction with Pheochromocytoma.
Methyldopa causes fluorescence in urine samples at the same wave lengths as catecholamines, falsely high levels of urinary catecholamines may be reported. This will interfere with the diagnosis of pheochromocytoma. It is important to recognize this phenomenon before a patient with a possible pheochromocytoma is subjected to surgery. Methyldopa is not recommended for the treatment of patients with pheochromocytoma.
Psychosis
Minor:
methyldopa
Methyldopa has a minor potential interaction with Psychosis.
Rare symptoms of psychoses, such as hallucinations and delirium, and vivid dreams and nightmares have been reported during methyldopa therapy. Therapy with methyldopa should be administered cautiously to patients with a history of or predisposition to these conditions.
Renal Dysfunction
Major:
Flavalta
The lidocaine in Flavalta has a major potential interaction with Renal Dysfunction.
Lidocaine is primarily eliminated by the kidney. Less than 10% is eliminated unchanged in the urine. Two active metabolites (MEGX and GX) have been identified that exhibit antiarrhythmic and convulsant properties. GX accumulates during prolonged intravenous lidocaine infusion. Serum concentrations of lidocaine and the active metabolites are increased and the half-life prolonged in patients with renal impairment. Therapy with lidocaine should be administered cautiously and dosing modified for repeated or maintenance doses in patients with compromised renal function. Clinical monitoring of cardiac function (continual ECG) is required and serum metabolite concentrations and monitoring renal function are recommended.
