Applies to: benzethonium chloride / lidocaine topical and silver nitrate topical
Some of the medication in silver nitrate topical may be absorbed into the bloodstream following local application. When present in sufficient concentrations in the blood, silver nitrate topical may cause methemoglobinemia, a rare condition that can lead to oxygen deprivation in tissues and vital organs due to reduced oxygen-carrying capacity of the blood. Methemoglobinemia is most likely to occur when silver nitrate topical is used in burn patients to prevent infection. The risk is increased when combined with other medications that can also induce methemoglobinemia such as lidocaine topical. Individuals may be more susceptible to developing methemoglobinemia during treatment with these medications if they are very young (especially neonates and infants) or have anemia, diseases of the heart or lungs, blood circulation disorders, liver cirrhosis, shock, sepsis, and certain genetic predispositions such as NADH cytochrome-b5 reductase deficiency, glucose-6-phosphate dehydrogenase deficiency, and hemoglobin M. In addition, use of silver nitrate topical on inflamed or abraded areas or broken skin, as well as excessive use such as application of large doses or on larger than recommended areas, can increase absorption and result in high blood levels of the medication. Close medical supervision may be necessary when medications that can cause methemoglobinemia are used together. Signs and symptoms of methemoglobinemia may be delayed by several hours after treatment. Patients (or their caregivers) should seek immediate medical attention if they develop a gray discoloration of the skin, mouth, or nail bed; nausea; headache; dizziness; lightheadedness; fatigue; shortness of breath; rapid or shallow breathing; a rapid heartbeat; palpitation; anxiety; or confusion. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Disease interactions
8 potential interactions Applies to: 8 conditions, including Seizures, Liver Disease, Hyponatremia, Heart Block, and Shock.
Electrolyte Abnormalities
Moderate:
silver nitrate topical
Silver nitrate topical has a moderate potential interaction with Electrolyte Abnormalities.
Electrolyte abnormalities of hyponatremia and hypochloremia have resulted from prolonged use of silver nitrate or application of wet dressings to extensive dermal areas. Sodium and chloride leech into dressings. Therapy with silver nitrate dressings should be applied cautiously in patients with or predisposition to electrolyte abnormalities. Clinical monitoring of electrolytes is recommended and electrolyte replacement as indicted.
Heart Block
Major:
benzethonium chloride / lidocaine topical
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.
Hyponatremia
Moderate:
silver nitrate topical
Silver nitrate topical has a moderate potential interaction with Hyponatremia.
Electrolyte abnormalities of hyponatremia and hypochloremia have resulted from prolonged use of silver nitrate or application of wet dressings to extensive dermal areas. Sodium and chloride leech into dressings. Therapy with silver nitrate dressings should be applied cautiously in patients with or predisposition to electrolyte abnormalities. Clinical monitoring of electrolytes is recommended and electrolyte replacement as indicted.
Liver Disease
Major:
benzethonium chloride / lidocaine topical
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.
Renal Dysfunction
Major:
benzethonium chloride / lidocaine topical
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.
Seizures
Major:
benzethonium chloride / lidocaine topical
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.
Shock
Major:
benzethonium chloride / lidocaine topical
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.
Teething Syndrome
Major:
benzethonium chloride / lidocaine topical
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.
