Interactions between your drugs

Moderate

flucytosine ibandronate

Applies to: flucytosine and ibandronate

MONITOR: Drugs that impair glomerular filtration may prolong the half-life of flucytosine and lead to accumulation. Prolonged flucytosine serum concentrations of greater than 100 mcg/mL may increase the risk of gastrointestinal, hepatic, and hematologic toxicity.

MANAGEMENT: Caution is advised if flucytosine is used in patients who have recently received or are receiving treatment with potentially nephrotoxic drugs (e.g., aminoglycosides; polypeptide, glycopeptide, and polymyxin antibiotics; amphotericin B; adefovir; cidofovir; tenofovir; foscarnet; cisplatin; deferasirox; gallium nitrate; lithium; mesalamine; certain immunosuppressants; intravenous bisphosphonates; intravenous pentamidine; high intravenous dosages of methotrexate; high dosages and/or chronic use of nonsteroidal anti-inflammatory agents). Renal function and flucytosine blood levels should be closely monitored during therapy, and the dose or dosing interval should be adjusted to maintain flucytosine concentrations below 100 mcg/mL.

Drug and food interactions

Moderate

ibandronate food

Applies to: ibandronate

ADJUST DOSING INTERVAL: Food significantly decreases the bioavailability of oral ibandronate. The manufacturer reports up to a 75% decrease in bioavailability when administered 2 hours after a standard meal.

MANAGEMENT: Oral ibandronate should be administered on an empty stomach (after an overnight fast of at least 6 hours) with a 180 to 240 mL glass of plain water and no other food or drink should be taken for at least 30 minutes after administration.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
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.
Unknown No interaction information available.
