Can you take Clarithromycin with RadiaGuard?

Clarithromycin has a moderate potential interaction with Arrhythmia.

Macrolides have been associated with prolongation of the QT interval and infrequent cases of arrhythmia. Clarithromycin and erythromycin should be avoided in: patients with known prolongation of the QT interval, ventricular cardiac arrhythmia, including torsades de pointes; patients with proarrhythmic conditions such as uncorrected hypokalemia or hypomagnesemia, clinically significant bradycardia, or receiving other drugs that prolong the QT interval.

The lidocaine topical in RadiaGuard 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.

Clarithromycin has a moderate potential interaction with Hypokalemia.

Macrolides have been associated with prolongation of the QT interval and infrequent cases of arrhythmia. Clarithromycin and erythromycin should be avoided in: patients with known prolongation of the QT interval, ventricular cardiac arrhythmia, including torsades de pointes; patients with proarrhythmic conditions such as uncorrected hypokalemia or hypomagnesemia, clinically significant bradycardia, or receiving other drugs that prolong the QT interval.

The lidocaine topical in RadiaGuard 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.

Clarithromycin has a moderate potential interaction with Liver Disease.

Hepatic dysfunction, including increased liver enzymes, and hepatocellular and/or cholestatic hepatitis, with or without jaundice, has been reported in patients receiving clarithromycin. The hepatic dysfunction may be severe but in most cases is reversible. Fatal outcomes have also been reported and in general have been associated with serious underlying diseases and/or concomitant medications. Caution and monitoring is advised if using this drug in patients with hepatic impairment. Treatment must be discontinued immediately if signs and symptoms of hepatitis occur (e.g., anorexia, jaundice, dark urine, pruritus, or tender abdomen). The use of clarithromycin and combination medications containing this antibiotic are contraindicated in patients with a history of cholestatic jaundice or hepatic impairment associated with the prior use of clarithromycin.

Clarithromycin has a moderate potential interaction with Magnesium Imbalance.

Macrolides have been associated with prolongation of the QT interval and infrequent cases of arrhythmia. Clarithromycin and erythromycin should be avoided in: patients with known prolongation of the QT interval, ventricular cardiac arrhythmia, including torsades de pointes; patients with proarrhythmic conditions such as uncorrected hypokalemia or hypomagnesemia, clinically significant bradycardia, or receiving other drugs that prolong the QT interval.

Clarithromycin has a moderate potential interaction with Myasthenia Gravis.

The use of macrolide antibiotics has been reported to exacerbate symptoms of myasthenia gravis and trigger new onset of symptoms of myasthenic syndrome. Therapy with these agents should be administered cautiously in patients with a history of myasthenia gravis.

Clarithromycin has a major potential interaction with Noninfectious Colitis.

Clostridioides difficile-associated diarrhea (CDAD), formerly pseudomembranous colitis, has been reported with almost all antibacterial drugs and may range from mild diarrhea to fatal colitis. The most common culprits include clindamycin and lincomycin. Antibacterial therapy alters the normal flora of the colon, leading to overgrowth of C difficile, whose toxins A and B contribute to CDAD development. Morbidity and mortality are increased with hypertoxin-producing strains of C difficile; these infections can be resistant to antimicrobial therapy and may require colectomy. CDAD must be considered in all patients who present with diarrhea after antibacterial use. Since CDAD has been reported to occur more than 2 months after antibacterial use, careful medical history is necessary. Therapy with broad-spectrum antibacterials and other agents with significant antibacterial activity should be administered cautiously in patients with history of gastrointestinal disease, particularly colitis; pseudomembranous colitis (generally characterized by severe, persistent diarrhea and severe abdominal cramps, and sometimes associated with the passage of blood and mucus), if it occurs, may be more severe in these patients and may be associated with flares in underlying disease activity. Antibacterial drugs not directed against C difficile may need to be stopped if CDAD is suspected or confirmed. Appropriate fluid and electrolyte management, protein supplementation, antibacterial treatment of C difficile, and surgical evaluation should be started as clinically indicated.

The lidocaine topical in RadiaGuard 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.

Clarithromycin has a moderate potential interaction with Renal Dysfunction.

Clarithromycin is primarily eliminated by the kidney and liver. A decreased dosage or prolonged dosing intervals are recommended in patients with severe renal impairment (CrCl < 30 mL/min). Dosage adjustments are usually not necessary in patients with mild to moderate renal impairment, although drug accumulation could occur in the presence of concomitant liver disease. Monitoring is advised.

The lidocaine topical in RadiaGuard 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 RadiaGuard 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 RadiaGuard 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.
