Interactions between your drugs

Moderate

etidronate telbivudine

Applies to: etidronate and telbivudine

MONITOR: Because telbivudine is primarily eliminated by renal excretion, coadministration with drugs that affect renal function may alter the plasma concentrations of telbivudine and/or the coadministered drug.

MANAGEMENT: Caution is advised if telbivudine is prescribed in combination 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 should be evaluated prior to and during therapy with telbivudine. Adjustment of dosing interval is required in patients with renal insufficiency (creatinine clearance below 50 mL/min) at baseline or during treatment in accordance with the manufacturer's product labeling.

Drug and food interactions

Moderate

etidronate food

Applies to: etidronate

ADJUST DOSING INTERVAL: Food, especially calcium-containing food such as dairy products, significantly decreases the bioavailability of oral etidronate.

MANAGEMENT: Oral etidronate should be administered on an empty stomach and no other food or drink should be taken within least 2 hours of administration.

Moderate

etidronate food

Applies to: etidronate

ADJUST DOSING INTERVAL: Products containing aluminum, calcium, magnesium and other polyvalent cations such as antacids or vitamin with mineral supplements are likely to interfere with the gastrointestinal absorption of oral bisphosphonates. For example, the bioavailability of tiludronate has been shown to decrease 80% during simultaneous administration with calcium, and 60% when aluminum- or magnesium-containing antacids were administered one hour before tiludronate.

MANAGEMENT: Antacids or other oral medications containing aluminum, calcium, magnesium and other polyvalent cations should be administered at least 2 hours before or 2 hours after the bisphosphonate dose.

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.
