Food/lifestyle interactions
Moderate food/lifestyle interactions
Moderate:
allopurinol Food/Lifestyle
Applies to: allopurinol
Allopurinol should generally be taken after a meal to reduce side effects. If your daily dose exceeds 300 mg, you may also ask your healthcare provider if it is okay to divide the total daily dose into smaller doses given more frequently instead of once a day, as this may also reduce stomach upset that can happen with allopurinol. It is best to avoid or limit the consumption of alcohol, as it can increase drowsiness or other nervous system side effects of allopurinol. You should also avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. 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.
Moderate:
erythromycin Food/Lifestyle
Applies to: Pediazole (erythromycin / sulfisoxazole)
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.

27 potential interactions Applies to: 20 conditions, including Allergies, Asthma, Diarrhea, Arrhythmia, and Hypokalemia.
Allergies
Major:
Pediazole
The sulfiSOXAZOLE in Pediazole has a major potential interaction with Allergies.
The use of sulfonamides is associated with large increases in the risk of Stevens-Johnson syndrome, toxic epidermal necrolysis and other serious dermatologic reactions, although these phenomena are rare as a whole. Hepatitis, pneumonitis, and interstitial nephritis have also occurred in association with sulfonamide hypersensitivity. Therapy with sulfonamides should be administered cautiously in patients with severe allergies, bronchial asthma or AIDS, since these patients may be at increased risk for potentially severe hypersensitivity reactions. Patients should be instructed to promptly report signs and symptoms that may precede the onset of cutaneous manifestations of the Stevens-Johnson syndrome, such as high fever, severe headache, stomatitis, conjunctivitis, rhinitis, urethritis, and balanitis. Sulfonamide therapy should be stopped at once if a rash develops.
Arrhythmia
Moderate:
Pediazole
The erythromycin in Pediazole 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.
Asthma
Major:
Pediazole
The sulfiSOXAZOLE in Pediazole has a major potential interaction with Asthma.
The use of sulfonamides is associated with large increases in the risk of Stevens-Johnson syndrome, toxic epidermal necrolysis and other serious dermatologic reactions, although these phenomena are rare as a whole. Hepatitis, pneumonitis, and interstitial nephritis have also occurred in association with sulfonamide hypersensitivity. Therapy with sulfonamides should be administered cautiously in patients with severe allergies, bronchial asthma or AIDS, since these patients may be at increased risk for potentially severe hypersensitivity reactions. Patients should be instructed to promptly report signs and symptoms that may precede the onset of cutaneous manifestations of the Stevens-Johnson syndrome, such as high fever, severe headache, stomatitis, conjunctivitis, rhinitis, urethritis, and balanitis. Sulfonamide therapy should be stopped at once if a rash develops.
Biliary Obstruction
Major:
Pediazole
The erythromycin in Pediazole 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.
Bone Marrow Depression/Low Blood Counts
Major:
Pediazole
The sulfiSOXAZOLE in Pediazole has a major potential interaction with Bone Marrow Depression/Low Blood Counts.
The use of sulfonamides has been associated with hematologic toxicity, including methemoglobinemia, sulfhemoglobinemia, leukopenia, granulocytopenia, eosinophilia, hemolytic anemia, aplastic anemia, purpura, clotting disorder, thrombocytopenia, hypofibrinogenemia, and hypoprothrombinemia. Acute dose-related hemolytic anemia may occur during the first week of therapy due to sensitization, while chronic hemolytic anemia may occur with prolonged use. Patients with glucose-6-phosphate dehydrogenase (G-6-PD) deficiency should be observed closely for signs of hemolytic anemia. Therapy with sulfonamides should be administered cautiously in patients with preexisting blood dyscrasias or bone marrow suppression. Complete blood counts should be obtained regularly, especially during prolonged therapy (>2 weeks), and patients should be instructed to immediately report any signs or symptoms suggestive of blood dyscrasia such as fever, sore throat, local infection, bleeding, pallor, dizziness, or jaundice.
Moderate:
allopurinol
Allopurinol has a moderate potential interaction with Bone Marrow Depression/Low Blood Counts.
Bone marrow suppression has been reported in patients receiving allopurinol; however, most of these patients were receiving concomitant medications with the known potential to cause such an effect. The suppression has occurred from as early as 6 weeks to as long as 6 years after the initiation of allopurinol therapy. Therapy with allopurinol should be administered cautiously to patients with or predisposed to bone marrow suppression.
Dehydration
Moderate:
allopurinol
Allopurinol has a moderate potential interaction with Dehydration.
Patients with pre-existing kidney conditions, including chronic kidney disease or a history of kidney stones, may be at increased risk for worsening of kidney function or acute kidney injury due to xanthine calculi during treatment with this drug. Ensure adequate hydration to maintain a daily urine output of at least 2 liters in adults and 2 liters/m2/day (or 100 mL/m2/hour) in pediatric patients. Maintaining a neutral to slightly alkaline urine pH is also recommended to prevent xanthine calculi and reduce urate precipitation. Renal function should be closely monitored, especially during the early stages of therapy.
Moderate:
Pediazole
The sulfiSOXAZOLE in Pediazole has a moderate potential interaction with Dehydration.
Crystalluria can occur during sulfonamide therapy due to precipitation of the sulfonamide and/or its N4-acetyl metabolite in the urinary tract. Renal toxicity such as uro- and nephrolithiasis, nephritis, toxic nephrosis, hematuria, proteinuria, and elevated BUN and creatinine has been reported. Hydration (8 oz. glass of water with each dose and throughout the day) and adequate urinary output (> 1.5 L/day) should be maintained during sulfonamide administration. Patients who are dehydrated (e.g., due to severe diarrhea or vomiting) may be at increased risk for the development of crystalluria and lithiasis and should be encouraged to consume additional amounts of liquid or given intravenous fluid. Renal function tests and urinalysis should be performed weekly during prolonged therapy (> 2 weeks). Rarely, alkalinization of the urine is necessary.

Myasthenia Gravis
Moderate:
Pediazole
The erythromycin in Pediazole 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:
Pediazole
The erythromycin and sulfiSOXAZOLE in Pediazole both have 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.
Porphyria
Major:
Pediazole
The sulfiSOXAZOLE in Pediazole has a major potential interaction with Porphyria.
The use of sulfonamides is contraindicated in patients with porphyria, since these drugs can precipitate an acute attack.
Prematurity/Underweight in Infancy
Major:
Pediazole
The erythromycin in Pediazole 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
Major:
Pediazole
The sulfiSOXAZOLE in Pediazole has a major potential interaction with Renal Dysfunction.
Sulfonamides and their metabolites are eliminated by the kidney. Patients with renal impairment may be at greater risk for adverse effects from sulfonamides due to decreased drug clearance. Dosage adjustments may be necessary and modifications should be based on the degree of renal impairment and severity of infection. Additionally, sulfonamides may cause renal toxicity secondary to crystalluria, including uro- and nephrolithiasis, nephritis, toxic nephrosis, hematuria, proteinuria, and elevated BUN and creatinine. Hydration (8 oz. glass of water with each dose and throughout the day) and adequate urinary output (> 1.5 L/day) should be maintained during sulfonamide administration. Renal function tests and urinalysis should be performed weekly or as often as indicated by the patient's status. Rarely, alkalinization of the urine is necessary.
Moderate:
allopurinol
Allopurinol has a moderate potential interaction with Renal Dysfunction.
Allopurinol and its primary active metabolite, oxipurinol, are eliminated by the kidneys, and any changes in renal function will likely increase exposure. Additionally, treatment with allopurinol may result in renal impairment due to formation of xanthine calculi or due to precipitation of urates in patients receiving concomitant uricosuric agents. Patients with pre-existing renal disease, may be at increased risk for worsening renal impairment due to xanthine calculi or precipitation of urates while receiving treatment. These patients require lower dosages of allopurinol than normal to control serum urate levels and close monitoring of laboratory parameters of renal function to reassess the patient's dosage. Treatment with allopurinol tablets has not been studied in pediatric patients with severe renal impairment (eGFR less than 20 mL/min) or on dialysis.
Urinary Retention
Moderate:
Pediazole
The sulfiSOXAZOLE in Pediazole has a moderate potential interaction with Urinary Retention.
Sulfonamides are excreted and concentrated in the urine. Therapy with sulfonamides should be administered cautiously in patients with urinary obstruction or retention, since excessive drug accumulation may occur. These patients may also be at increased risk for sulfonamide crystalluria, which may be associated with renal toxicity such as uro- and nephrolithiasis, nephritis, toxic nephrosis, hematuria, proteinuria, and elevated BUN and creatinine. A urinary output of at least 1.5 L/day should be maintained during sulfonamide administration. Renal function tests and urinalysis should be performed weekly, especially during prolonged therapy (> 2 weeks).
Vomiting
Moderate:
allopurinol
Allopurinol has a moderate potential interaction with Vomiting.
Patients with pre-existing kidney conditions, including chronic kidney disease or a history of kidney stones, may be at increased risk for worsening of kidney function or acute kidney injury due to xanthine calculi during treatment with this drug. Ensure adequate hydration to maintain a daily urine output of at least 2 liters in adults and 2 liters/m2/day (or 100 mL/m2/hour) in pediatric patients. Maintaining a neutral to slightly alkaline urine pH is also recommended to prevent xanthine calculi and reduce urate precipitation. Renal function should be closely monitored, especially during the early stages of therapy.
Moderate:
Pediazole
The sulfiSOXAZOLE in Pediazole has a moderate potential interaction with Vomiting.
Crystalluria can occur during sulfonamide therapy due to precipitation of the sulfonamide and/or its N4-acetyl metabolite in the urinary tract. Renal toxicity such as uro- and nephrolithiasis, nephritis, toxic nephrosis, hematuria, proteinuria, and elevated BUN and creatinine has been reported. Hydration (8 oz. glass of water with each dose and throughout the day) and adequate urinary output (> 1.5 L/day) should be maintained during sulfonamide administration. Patients who are dehydrated (e.g., due to severe diarrhea or vomiting) may be at increased risk for the development of crystalluria and lithiasis and should be encouraged to consume additional amounts of liquid or given intravenous fluid. Renal function tests and urinalysis should be performed weekly during prolonged therapy (> 2 weeks). Rarely, alkalinization of the urine is necessary.
