Drug interactions
Minor drug interactions
Minor:
erythromycin ulipristal
Applies to: Ilosone (erythromycin) and ulipristal
Coadministration with CYP450 3A4 inhibitors may increase the plasma concentrations of ulipristal, which is primarily metabolized by the isoenzyme. The clinical relevance is unknown.
The information above is from our professional interaction data. Consumer information is not available for this interaction.
Food/lifestyle interactions
Moderate food/lifestyle interactions
Moderate:
erythromycin Food/Lifestyle
Applies to: Ilosone (erythromycin)
Food decreases the levels of erythromycin in your body. Take erythromycin on an empty stomach at least 30 minutes before or 2 hours after a meal. This will make it easier for your body to absorb the medication.
However, some erythromycin products may be taken without regard to meals. Ask your healthcare provider about your particular prescription if you are uncertain of how to take it.
Grapefruits and grapefruit juice may increase erythromycin levels but how this may affect you is not known. Do not increase or decrease the amount of grapefruit products in your diet without first talking to your doctor.
Minor food/lifestyle interactions
Minor:
erythromycin Alcohol (Ethanol)
Applies to: Ilosone (erythromycin)
Ethanol, when combined with erythromycin, may delay absorption and therefore the clinical effects of the antibiotic. The mechanism appears to be due to slowed gastric emptying by ethanol. Data is available only for erythromycin ethylsuccinate. Patients should be advised to avoid ethanol while taking erythromycin salts.

Disease interactions
10 potential interactions Applies to: 9 conditions, including Arrhythmia, Hypokalemia, Myasthenia Gravis, Liver Disease, and Noninfectious Colitis.
Arrhythmia
Moderate:
Ilosone
The erythromycin in Ilosone 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.
Biliary Obstruction
Major:
Ilosone
The erythromycin in Ilosone has a major potential interaction with Biliary Obstruction.
The use of oral erythromycin, especially erythromycin estolate and erythromycin ethylsuccinate, has been associated with occasional cases of hepatic dysfunction, including elevated liver enzymes and hepatocellular and/or cholestatic hepatitis. Therapy with oral erythromycin should be administered cautiously in patients with liver disease. Additionally, erythromycin is primarily excreted by the liver into the bile. The effect of liver and/or biliary disease on erythromycin clearance is unknown. Empiric dosage adjustments may be appropriate in patients with impaired hepatic or biliary function.
Hypokalemia
Moderate:
Ilosone
The erythromycin in Ilosone 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.
Liver Disease
Major:
Ilosone
The erythromycin in Ilosone has a major potential interaction with Liver Disease.
The use of oral erythromycin, especially erythromycin estolate and erythromycin ethylsuccinate, has been associated with occasional cases of hepatic dysfunction, including elevated liver enzymes and hepatocellular and/or cholestatic hepatitis. Therapy with oral erythromycin should be administered cautiously in patients with liver disease. Additionally, erythromycin is primarily excreted by the liver into the bile. The effect of liver and/or biliary disease on erythromycin clearance is unknown. Empiric dosage adjustments may be appropriate in patients with impaired hepatic or biliary function.
Moderate:
ulipristal
Ulipristal has a moderate potential interaction with Liver Disease.
No studies have been conducted to evaluate the effect of hepatic disease on the disposition of ulipristal. Caution is recommended when using this agent in patients with liver disease.
Magnesium Imbalance
Moderate:
Ilosone
The erythromycin in Ilosone 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.
Myasthenia Gravis
Moderate:
Ilosone
The erythromycin in Ilosone 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.
Noninfectious Colitis
Major:
Ilosone
The erythromycin in Ilosone 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.
Prematurity/Underweight in Infancy
Major:
Ilosone
The erythromycin in Ilosone has a major potential interaction with Prematurity/Underweight in Infancy.
Parenteral medications formulated in multidose vials often contain benzyl alcohol as a preservative. Their use is considered by drug manufacturers to be contraindicated in neonates, particularly premature infants and infants of low birth weight. When used in bacteriostatic saline intravascular flush and endotracheal tube lavage solutions, benzyl alcohol has been associated with fatalities and severe respiratory and metabolic complications in low-birth-weight premature infants. Thus, single-dose formulations should always be used in infants whenever possible. However, many experts feel that, in the absence of benzyl alcohol-free equivalents, the amount of the preservative present in these formulations should not necessarily preclude their use if they are clearly indicated. The American Academy of Pediatrics considers benzyl alcohol in low doses (such as when used as a preservative in some medications) to be safe for newborns. However, the administration of high dosages of these medications must take into account the total amount of benzyl alcohol administered. The level at which toxicity may occur is unknown.
Renal Dysfunction
Moderate:
ulipristal
Ulipristal has a moderate potential interaction with Renal Dysfunction.
No studies have been conducted to evaluate the effect of renal disease on the disposition of ulipristal. Caution is recommended when using this agent in patients with renal impairment.
