Can you take Benzethonium chloride / lidocaine topical with Voriconazole?

Voriconazole has a moderate potential interaction with Arrhythmia.

Some azole antifungals have been associated with prolongation of the QT interval on the ECG. Rare cases of QT prolongation and torsade de pointes have been reported during postmarketing experience; such reports usually involved seriously ill patients with multiple confounding risk factors, such as structural heart disease, electrolyte abnormalities, and concomitant medications. These drugs should be administered with caution to patients with potentially proarrhythmic conditions, such as congenital/acquired QT prolongation, cardiomyopathy (especially when heart failure is present), sinus bradycardia, and existing symptomatic arrhythmias. Concomitant use with other medications that have potential to increase the risk of cardiotoxicity should be avoided.

Voriconazole has a moderate potential interaction with Bone Marrow Transplantation.

Patients with risk factors for acute pancreatitis (e.g., recent chemotherapy, hematopoietic stem cell transplantation) should be monitored for the development of pancreatitis during voriconazole therapy.

Voriconazole has a moderate potential interaction with Electrolyte Abnormalities.

Electrolyte disturbances (such as hypokalemia, hypomagnesemia, and hypocalcemia) should be monitored and corrected before and during voriconazole therapy.

Voriconazole has a moderate potential interaction with Galactosemia.

Voriconazole tablets contain lactose and should not be given to patients with galactose intolerance, total lactase deficiency, or glucose-galactose malabsorption. Voriconazole oral suspension contains sucrose.

The lidocaine topical in benzethonium chloride / lidocaine topical has a major potential interaction with Heart Block.

Lidocaine is absorbed through intact skin and mucosal membranes following topical administration. Prolonged exposure, large doses, frequent applications and/or use on compromised skin or mucosa can produce systemic effects. At high plasma levels, lidocaine can cause hypotension, bradycardia, and cardiovascular collapse. Therapy with lidocaine topical should be administered cautiously in patients with shock, sinus bradyarrhythmia, or severe heart block. The recommended dosage should not be exceeded. Children and debilitated, elderly, or acutely ill patients should be given reduced dosages commensurate with their age, weight, and physical condition.

Voriconazole has a moderate potential interaction with Lactose Intolerance.

Voriconazole tablets contain lactose and should not be given to patients with galactose intolerance, total lactase deficiency, or glucose-galactose malabsorption. Voriconazole oral suspension contains sucrose.

The lidocaine topical in benzethonium chloride / lidocaine topical has a major potential interaction with Liver Disease.

Lidocaine topical is absorbed through intact skin and mucosal membranes. Prolonged exposure, large doses, and/or application to compromised skin or mucosa can result in elevated plasma concentrations of lidocaine. 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. The pharmacokinetic disposition of lidocaine is altered by changes in hepatic function, including hepatic blood flow. Therapy with lidocaine topical should be administered cautiously and dosing modified for patients with compromised hepatic function.

Voriconazole has a moderate potential interaction with Liver Disease.

Serious hepatic reactions (including clinical hepatitis, cholestasis, fulminant hepatic failure [including fatalities]) have been reported infrequently during voriconazole therapy. Hepatic reactions have primarily occurred in patients with serious underlying medical conditions (mainly hematological malignancy). Serum transaminase levels and bilirubin should be measured at the start of and during voriconazole therapy, according to the manufacturer product information.

Voriconazole is primarily metabolized by the liver and has been shown to accumulate significantly in patients with impaired hepatic function. Adult patients with baseline liver function tests (ALT, AST) of up to 5 times the upper limit of normal do not require dose adjustments; however, liver function tests should continue to be monitored for further elevations. The manufacturer recommends that the maintenance dose be halved in adult patients with mild to moderate liver dysfunction/cirrhosis (Child-Pugh A and B). Voriconazole has not been studied in adult patients with severe liver dysfunction/cirrhosis (Child-Pugh C) or in patients with chronic hepatitis B or C; no dosing recommendations are available for patients with severe liver dysfunction. Voriconazole should only be used in patients with severe liver dysfunction if the benefit outweighs the potential risk. Patients with liver dysfunction must be carefully monitored for drug toxicity. Dosage adjustment has not been established in pediatric patients with liver dysfunction.

Voriconazole has a moderate potential interaction with Myeloproliferative Disorders.

The lidocaine topical in benzethonium chloride / lidocaine topical has a major potential interaction with Renal Dysfunction.

Lidocaine topical is absorbed through intact skin and mucosal membranes. Prolonged exposure, large doses, and/or application to compromised skin or mucosa can result in elevated plasma concentrations of lidocaine. 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. Serum concentrations of lidocaine and the active metabolites are increased and the half-life prolonged in patients with renal impairment. Therapy with lidocaine topical should be administered cautiously and dosing modified for repeated doses in patients with compromised renal function.

Voriconazole has a moderate potential interaction with Renal Dysfunction.

The pharmacokinetics of voriconazole are not significantly altered by impaired renal function. However, accumulation of the IV vehicle, sulfobutyl ether beta-cyclodextrin sodium (SBECD), occurs in patients with moderate or severe renal dysfunction (CrCl less than 50 mL/min). The mean systemic exposure (AUC) and Cmax of SBECD were increased 4-fold and almost 50%, respectively, in moderately impaired patients compared to controls with normal renal function. The manufacturer recommends that oral voriconazole be used in patients with moderate to severe renal dysfunction, unless after assessing the benefit/risk to the patient, use of IV voriconazole is justified; serum creatinine levels should be monitored closely in these patients, and if increases occur, switching to oral voriconazole should be considered. No dosage adjustment is necessary when using oral voriconazole. Monitoring of renal function (including laboratory evaluation of serum creatinine) is recommended. Dosage adjustment has not been established in pediatric patients with renal dysfunction.

The lidocaine topical in benzethonium chloride / lidocaine topical has a major potential interaction with Seizures.

Lidocaine topical is absorbed through intact skin and mucosal membranes. Prolonged exposure, large doses, and/or application to compromised skin or mucosa can result in elevated plasma concentrations of lidocaine. Seizures can occur as a result of accumulation of active metabolites. Therapy with lidocaine topical should be administered cautiously to patients with or predisposed to seizure disorders.

The lidocaine topical in benzethonium chloride / lidocaine topical has a major potential interaction with Shock.

Lidocaine is absorbed through intact skin and mucosal membranes following topical administration. Prolonged exposure, large doses, frequent applications and/or use on compromised skin or mucosa can produce systemic effects. At high plasma levels, lidocaine can cause hypotension, bradycardia, and cardiovascular collapse. Therapy with lidocaine topical should be administered cautiously in patients with shock, sinus bradyarrhythmia, or severe heart block. The recommended dosage should not be exceeded. Children and debilitated, elderly, or acutely ill patients should be given reduced dosages commensurate with their age, weight, and physical condition.

The lidocaine topical in benzethonium chloride / lidocaine topical has a major potential interaction with Teething Syndrome.

Topical lidocaine is not recommended to be used in teething infants and young children, as its ingestion is dangerous and potentially fatal. Ingestion of the drug has shown to result in seizures, severe brain injury, and heart problems in children.
