Amoxicillin / clarithromycin / lansoprazole Disease Interactions

There are 8 disease interactions with amoxicillin / clarithromycin / lansoprazole:

Aminopenicillins (Includes Amoxicillin/clarithromycin/lansoprazole) ↔ Mononucleosis

Moderate Potential Hazard, High plausibility

Applies to: Mononucleosis

Patients with mononucleosis treated with an aminopenicillin antibiotic, particularly ampicillin, quite frequently develop a pruritic erythematous maculopapular skin rash that generally occurs 5 to 10 days after therapy is initiated. The rash is usually self-limiting and resolves within days of discontinuing the offending agent. An altered drug metabolism or an immune-mediated process unrelated to drug hypersensitivity has been proposed as the underlying mechanism. Clinicians should recognize that a skin eruption under this circumstance does not necessarily indicate a life-long allergy to these agents or other penicillin derivatives. Therapy with aminopenicillin antibiotics may not be appropriate in patients with mononucleosis.

Amoxicillin-Clavulanate (Includes Amoxicillin/clarithromycin/lansoprazole) ↔ Pku

Moderate Potential Hazard, High plausibility

Applies to: Phenylketonuria

Augmentin (brand of amoxicillin-clavulanate) chewable tablets contain 2.1 mg of phenylalanine per each 200 mg tablet and 4.2 mg of phenylalanine per each 400 mg tablet. Augmentin oral suspension contains 7 mg of phenylalanine per each 5 mL of reconstituted suspension for both the 200 mg/5 mL and 400 mg/5 mL strengths. The phenylalanine content should be considered when these products are used in patients who must restrict their intake of phenylalanine (i.e. phenylketonurics).

Antibiotics (Includes Amoxicillin/clarithromycin/lansoprazole) ↔ Colitis

Moderate Potential Hazard, Moderate plausibility

Applies to: Colitis/Enteritis (Noninfectious), Colitis/Enteritis (Noninfectious)

Pseudomembranous colitis has been reported with most antibacterial agents and may range in severity from mild to life-threatening, with an onset of up to two months following cessation of therapy. Antibiotic therapy can alter the normal flora of the colon and permit overgrowth of Clostridium difficile, whose toxin is believed to be a primary cause of antibiotic-associated colitis. The colitis is usually characterized by severe, persistent diarrhea and severe abdominal cramps, and may be associated with the passage of blood and mucus. The most common culprits are clindamycin, lincomycin, the aminopenicillins (amoxicillin, ampicillin), and the cephalosporins. Therapy with broad-spectrum antibiotics and other agents with significant antibacterial activity should be administered cautiously in patients with a history of gastrointestinal diseases, particularly colitis. There is some evidence that pseudomembranous colitis, if it occurs, may run a more severe course in these patients and that it may be associated with flares in their underlying disease activity. The offending antibiotic(s) should be discontinued if significant diarrhea occurs during therapy. Stool cultures for Clostridium difficile and stool assay for C. difficile toxin may be helpful diagnostically. A large bowel endoscopy may be considered to establish a definitive diagnosis in cases of severe diarrhea.

Beta-Lactams (Oral) (Includes Amoxicillin/clarithromycin/lansoprazole) ↔ Renal Dysfunction

Moderate Potential Hazard, High plausibility

Applies to: Renal Dysfunction

Most beta-lactam antibiotics are eliminated by the kidney as unchanged drug and, in some cases, also as metabolites. The serum concentrations of beta-lactam antibiotics and their metabolites may be increased and the half-lives prolonged in patients with impaired renal function. Dosage adjustments may be necessary and modifications should be based on the degree of renal impairment as well as severity of infection in accordance with the individual product package labeling. Renal function tests should be performed periodically during prolonged and/or high-dose therapy, since nephrotoxicity and alterations in renal function have occasionally been associated with the use of these drugs.

Clarithromycin (Includes Amoxicillin/clarithromycin/lansoprazole) ↔ Renal Dysfunction

Moderate Potential Hazard, High plausibility

Applies to: Renal Dysfunction

Clarithromycin and its primary, active metabolite are both eliminated by the kidney to some extent. The daily dosage should be halved 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 theoretically, drug accumulation could occur in these patients if they have concomitant liver disease.

Lansoprazole (Includes Amoxicillin/clarithromycin/lansoprazole) ↔ Liver Disease

Moderate Potential Hazard, Moderate plausibility

Applies to: Liver Disease

Lansoprazole is primarily metabolized by the liver. Although the drug is generally well-tolerated, dosage adjustments with cautious titration should be considered in patients with severe hepatic impairment.

Macrolide Antibiotics (Includes Amoxicillin/clarithromycin/lansoprazole) ↔ Myasthenia Gravis

Moderate Potential Hazard, Moderate plausibility

Applies to: 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. Limited data suggest presynaptic suppression of acetylcholine release. Therapy with these agents should be administered cautiously in patients with a history of myasthenia gravis.

Penicillins (Includes Amoxicillin/clarithromycin/lansoprazole) ↔ Hemodialysis

Moderate Potential Hazard, High plausibility

Applies to: hemodialysis

Penicillin antibiotics (except for agents in the penicillinase-resistant class) are removed by hemodialysis. Doses should either be scheduled for administration after dialysis or supplemental doses be given after dialysis.

Drug Interaction Classification

The classifications below are a general guideline only. It is difficult to determine the relevance of a particular drug interaction to any individual given the large number of variables.

Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
