Disease interactions

37 potential interactions Applies to: 29 conditions, including Depression, Allergies, Heart Failure, Asthma, and COPD.

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.

Moderate:

zonisamide

Zonisamide has a moderate potential interaction with Acidosis.

Reduced plasma bicarbonate levels and, in some instances, elevated plasma chloride levels may result in metabolic acidosis during long-term therapy with carbonic anhydrase inhibitors. Therapy with carbonic anhydrase inhibitors should be administered cautiously in patients with metabolic or hyperchloremic acidosis or with conditions that predispose to acidosis (renal disease, severe respiratory disorders, diarrhea). The measurement of baseline and periodic serum bicarbonate is recommended. If metabolic acidosis develops (it may be corrected by administration of sodium bicarbonate), and persists, a dose reduction or treatment discontinuation should be considered.

Allergies

Major:

zonisamide

Zonisamide has a major potential interaction with Allergies.

The use of sulfonamides is associated with large increases in the risk of Stevens-Johnson syndrome, toxic epidermal necrolysis and other serious dermatologic reactions, although these phenomena are rare as a whole. Hepatitis, pneumonitis, and interstitial nephritis have also occurred in association with sulfonamide hypersensitivity. Therapy with sulfonamides should be administered cautiously in patients with severe allergies, bronchial asthma or AIDS, since these patients may be at increased risk for potentially severe hypersensitivity reactions. Patients should be instructed to promptly report signs and symptoms that may precede the onset of cutaneous manifestations of the Stevens-Johnson syndrome, such as high fever, severe headache, stomatitis, conjunctivitis, rhinitis, urethritis, and balanitis. Sulfonamide therapy should be stopped at once if a rash develops.

Asthma

Major:

zonisamide

Zonisamide has a major potential interaction with Asthma.

The use of sulfonamides is associated with large increases in the risk of Stevens-Johnson syndrome, toxic epidermal necrolysis and other serious dermatologic reactions, although these phenomena are rare as a whole. Hepatitis, pneumonitis, and interstitial nephritis have also occurred in association with sulfonamide hypersensitivity. Therapy with sulfonamides should be administered cautiously in patients with severe allergies, bronchial asthma or AIDS, since these patients may be at increased risk for potentially severe hypersensitivity reactions. Patients should be instructed to promptly report signs and symptoms that may precede the onset of cutaneous manifestations of the Stevens-Johnson syndrome, such as high fever, severe headache, stomatitis, conjunctivitis, rhinitis, urethritis, and balanitis. Sulfonamide therapy should be stopped at once if a rash develops.

Bone Marrow Depression/Low Blood Counts

Major:

zonisamide

Zonisamide has a major potential interaction with Bone Marrow Depression/Low Blood Counts.

The use of carbonic anhydrase inhibitors may rarely cause bone marrow suppression and blood dyscrasias at recommended dosages. Aplastic anemia, thrombocytopenia or thrombocytopenia purpura, leukopenia, agranulocytosis, and hemolytic anemia have been reported. Extreme caution should be exercised if carbonic anhydrase inhibitors are administered to patients with these preexisting conditions. A baseline CBC and platelet count is recommended, as well as monitoring at regular intervals during therapy.

Major:

zonisamide

Zonisamide has a major potential interaction with Bone Marrow Depression/Low Blood Counts.

The use of sulfonamides has been associated with hematologic toxicity, including methemoglobinemia, sulfhemoglobinemia, leukopenia, granulocytopenia, eosinophilia, hemolytic anemia, aplastic anemia, purpura, clotting disorder, thrombocytopenia, hypofibrinogenemia, and hypoprothrombinemia. Acute dose-related hemolytic anemia may occur during the first week of therapy due to sensitization, while chronic hemolytic anemia may occur with prolonged use. Patients with glucose-6-phosphate dehydrogenase (G-6-PD) deficiency should be observed closely for signs of hemolytic anemia. Therapy with sulfonamides should be administered cautiously in patients with preexisting blood dyscrasias or bone marrow suppression. Complete blood counts should be obtained regularly, especially during prolonged therapy (>2 weeks), and patients should be instructed to immediately report any signs or symptoms suggestive of blood dyscrasia such as fever, sore throat, local infection, bleeding, pallor, dizziness, or jaundice.

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.

COPD

Moderate:

zonisamide

Zonisamide has a moderate potential interaction with COPD.

Reduced plasma bicarbonate levels and, in some instances, elevated plasma chloride levels may result in metabolic acidosis during long-term therapy with carbonic anhydrase inhibitors. Therapy with carbonic anhydrase inhibitors should be administered cautiously in patients with metabolic or hyperchloremic acidosis or with conditions that predispose to acidosis (renal disease, severe respiratory disorders, diarrhea). The measurement of baseline and periodic serum bicarbonate is recommended. If metabolic acidosis develops (it may be corrected by administration of sodium bicarbonate), and persists, a dose reduction or treatment discontinuation should be considered.

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.

Moderate:

zonisamide

Zonisamide has a moderate potential interaction with Dehydration.

The use of zonisamide may infrequently be associated with the development of nephrolithiasis. The reported incidence for clinically possible or confirmed kidney stones was 4.0% (40 of 991 patients) during premarketing use, representing a rate of 34 per 1000 patient-years of exposure (40 patients with 1168 years of exposure). Therapy with zonisamide should be administered cautiously with adequate hydration in patients with a history of nephrolithiasis. Patients who are dehydrated may be at increased risk for the development of nephrolithiasis and should be encouraged to consume additional amounts of liquid during zonisamide therapy.

Depression

Major:

zonisamide

Zonisamide has a major potential interaction with Depression.

Antiepileptic drugs including zonisamide can increase depression and suicidal thoughts or behaviors in patients receiving these drugs for any indication. Patients should be monitored for the emergence or worsening of depression, suicidal thoughts and unusual changes in mood or behavior. Caregivers and family should be alert for the emergence or worsening of symptoms. Behaviors of concern should be reported immediately to the healthcare providers.

Moderate:

zonisamide

Zonisamide has a moderate potential interaction with Depression.

Antiepileptic drugs (AEDs) have been associated with an increased risk of suicidal thoughts or behavior in patients taking these drugs for any indication. Pooled analyses of 199 placebo-controlled clinical studies involving the use of 11 different AEDs showed that patients receiving AEDs had approximately twice the risk of suicidal thinking or behavior compared to patients receiving placebo. AEDs should be administered cautiously in patients with depression or other psychiatric disorders; phentermine-topiramate should be avoided in patients with history of suicidal attempts or active suicidal ideation. The risk of suicidal thoughts and behavior should be carefully assessed against the risk of untreated illness, bearing in mind that epilepsy and many other conditions for which AEDs are prescribed are themselves associated with morbidity and mortality and an increased risk of suicidal thoughts and behavior. Patients, caregivers, and families should be alert to the emergence or worsening of signs and symptoms of depression, any unusual changes in mood or behavior, or the emergence of suicidal thoughts or behavior. If patients have symptoms of suicidal ideation or behavior, a dosage reduction or treatment discontinuation should be considered.

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.

Diarrhea

Moderate:

zonisamide

Zonisamide has a moderate potential interaction with Diarrhea.

Reduced plasma bicarbonate levels and, in some instances, elevated plasma chloride levels may result in metabolic acidosis during long-term therapy with carbonic anhydrase inhibitors. Therapy with carbonic anhydrase inhibitors should be administered cautiously in patients with metabolic or hyperchloremic acidosis or with conditions that predispose to acidosis (renal disease, severe respiratory disorders, diarrhea). The measurement of baseline and periodic serum bicarbonate is recommended. If metabolic acidosis develops (it may be corrected by administration of sodium bicarbonate), and persists, a dose reduction or treatment discontinuation should be considered.

Fever

Major:

zonisamide

Zonisamide has a major potential interaction with Fever.

Oligohidrosis (decreased sweating) and hyperthermia have been reported in association with the use of some carbonic anhydrase inhibitor anticonvulsants such as topiramate and zonisamide. Most of the reports have been in children. Caution and close monitoring of body temperature is advised when prescribing these drugs, especially in patients with a fever, in hot weather, or if combined with other drugs that predispose to heat related disorders. Zonisamide is not approved for use in pediatric patients in the U.S.

Heart Block

Major:

Flavalta

The lidocaine in Flavalta has a major potential interaction with Heart Block.

Heart Failure

Major:

Flavalta

The lidocaine in Flavalta has a major potential interaction with Heart Failure.

Antiarrhythmic agents can induce severe hypotension (particularly with IV administration) or induce or worsen congestive heart failure (CHF). Patients with primary cardiomyopathy or inadequately compensated CHF are at increased risk. Antiarrhythmic agents should be administered cautiously and dosage and/or frequency of administration modified in patients with hypotension or adequately compensated CHF. Alternative therapy should be considered unless these conditions are secondary to cardiac arrhythmia.

History, Nephrolithiasis

Moderate:

zonisamide

Zonisamide has a moderate potential interaction with History, Nephrolithiasis.

The use of zonisamide may infrequently be associated with the development of nephrolithiasis. The reported incidence for clinically possible or confirmed kidney stones was 4.0% (40 of 991 patients) during premarketing use, representing a rate of 34 per 1000 patient-years of exposure (40 patients with 1168 years of exposure). Therapy with zonisamide should be administered cautiously with adequate hydration in patients with a history of nephrolithiasis. Patients who are dehydrated may be at increased risk for the development of nephrolithiasis and should be encouraged to consume additional amounts of liquid during zonisamide therapy.

History of Blood Dyscrasias

Major:

zonisamide

Zonisamide has a major potential interaction with History of Blood Dyscrasias.

The use of carbonic anhydrase inhibitors may rarely cause bone marrow suppression and blood dyscrasias at recommended dosages. Aplastic anemia, thrombocytopenia or thrombocytopenia purpura, leukopenia, agranulocytosis, and hemolytic anemia have been reported. Extreme caution should be exercised if carbonic anhydrase inhibitors are administered to patients with these preexisting conditions. A baseline CBC and platelet count is recommended, as well as monitoring at regular intervals during therapy.

HIV-1 Infection

Major:

zonisamide

Zonisamide has a major potential interaction with HIV-1 Infection.

The use of sulfonamides is associated with large increases in the risk of Stevens-Johnson syndrome, toxic epidermal necrolysis and other serious dermatologic reactions, although these phenomena are rare as a whole. Hepatitis, pneumonitis, and interstitial nephritis have also occurred in association with sulfonamide hypersensitivity. Therapy with sulfonamides should be administered cautiously in patients with severe allergies, bronchial asthma or AIDS, since these patients may be at increased risk for potentially severe hypersensitivity reactions. Patients should be instructed to promptly report signs and symptoms that may precede the onset of cutaneous manifestations of the Stevens-Johnson syndrome, such as high fever, severe headache, stomatitis, conjunctivitis, rhinitis, urethritis, and balanitis. Sulfonamide therapy should be stopped at once if a rash develops.

Hyperkalemia

Moderate:

Flavalta

The lidocaine in Flavalta has a moderate potential interaction with Hyperkalemia.

Electrolyte imbalance can alter the therapeutic effectiveness of antiarrhythmic agents. Hypokalemia and hypomagnesemia can reduce the effectiveness of antiarrhythmic agents. In some cases, these disorders can exaggerate the degree of QTc prolongation and increase the potential for torsade de pointes. Hyperkalemia can potentiate the toxic effects of antiarrhythmic agents. Electrolyte imbalance should be corrected prior to initiating antiarrhythmic therapy. Clinical monitoring of cardiac function and electrolyte concentrations is recommended.

Hyperthyroidism

Major:

Flavalta

Patients with primary cardiomyopathy or inadequately compensated CHF are at increased risk. Antiarrhythmic agents should be administered cautiously and dosage and/or frequency of administration modified in patients with hypotension or adequately compensated CHF. 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:

zonisamide

Zonisamide has a major potential interaction with Liver Disease.

The use of carbonic anhydrase inhibitors is contraindicated in patients with marked liver disease or cirrhosis. Carbonic anhydrase inhibitors increase the risk of developing hepatic encephalopathy in these patients. Extreme caution should be exercised if carbonic anhydrase inhibitors are administered in patients with mild to moderate liver disease as the clearance of the drug can be decreased. A dose reduction might be needed and monitoring of the liver function is recommended.

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.
