The use of certain antimalarial agents is contraindicated in patients with known prolongation of QT interval as these patients can develop fatal arrhythmias. These drugs should also be avoided in patients with clinical conditions known to prolong the QT interval, such as uncorrected hypokalemia or hypomagnesemia, bradycardia, and certain other cardiac conditions. Caution is advised in patients taking other medications that can prolong the QT interval.

Psychosis

Major:

interferon alfa-2b

Interferon alfa-2b has a major potential interaction with Psychosis.

Reversible CNS effects such as seizures, mental status changes, manic behavior or psychotic reactions, gait disturbances, and dizziness have occurred in patients receiving interferons. Therapy with interferons should be administered cautiously in patients with or predisposed to seizures, psychiatric disorders, or conditions affecting posture or gait.

Pulmonary Impairment

Major:

amiodarone

Amiodarone has a major potential interaction with Pulmonary Impairment.

Pulmonary toxicities such as hypersensitivity pneumonitis or interstitial/alveolar pneumonitis are potentially fatal (approximately 10% of the time) and have occurred in as many as 10% to 17% of patients administered daily dosages of approximately 400 mg of amiodarone. More frequently, asymptomatic abnormal diffusion capacity has been observed. Patients with preexisting pulmonary dysfunction does not appear to have an increased risk of pulmonary toxicity; however, they have a poorer prognosis if toxicity does develop. Thus, the risks and benefits of amiodarone therapy should be weighed carefully. Clinical monitoring of pulmonary function, including chest X-ray (baseline and every 3 to 6 months) and pulmonary function tests (with diffusion capacity), is recommended in all patients receiving amiodarone therapy. Any new respiratory symptom during treatment should be evaluated promptly and thoroughly, since toxicity is more likely to be reversible if diagnosed and managed early. Patients who develop hypersensitivity pneumonitis should be withdrawn permanently from amiodarone therapy and treated with steroids. In the case of interstitial/alveolar pneumonitis, steroid therapy and dosage reduction or discontinuation of amiodarone, if possible, usually result in clinical improvement. Subsequent rechallenge with amiodarone at reduced dosages does not always lead to return of toxicity and may be considered in some patients. The use of a lower loading dose and maintenance doses may also decrease the incidence of amiodarone- induced pulmonary toxicity.

Renal Dysfunction

Major:

interferon alfa-2b

Interferon alfa-2b has a major potential interaction with Renal Dysfunction.

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).

Seizures

Major:

interferon alfa-2b

Interferon alfa-2b has a major potential interaction with Seizures.

Reversible CNS effects such as seizures, mental status changes, manic behavior or psychotic reactions, gait disturbances, and dizziness have occurred in patients receiving interferons. Therapy with interferons should be administered cautiously in patients with or predisposed to seizures, psychiatric disorders, or conditions affecting posture or gait.
