Didronel IV (etidronate) Disease Interactions

There are 3 disease interactions with Didronel IV (etidronate):

Major

Etidronate (Includes Didronel IV) ↔ Osteomalacia

Severe Potential Hazard, High plausibility

Applies to: Vitamin D Deficiency

The use of etidronate (for the treatment of Paget's disease or the treatment/prevention of heterotopic ossification) is contraindicated in patients with clinically overt osteomalacia. Etidronate can inhibit bone mineralization, which has resulted in osteomalacia and bone fractures in some patients. Accumulation of unmineralized osteoid is usually noticeable during prolonged, continuous use of high dosages (10 to 20 mg/kg/day) but may occur at lower dosages when use exceeds 6 months. The newer bisphosphonates (e.g., alendronate, pamidronate, risedronate, and tiludronate) do not cause mineralization defects and may be more appropriate for patients with osteomalacia, although clinical data may be lacking for the treatment of some conditions for which etidronate is used.

Major

Etidronate (Includes Didronel IV) ↔ Upper Gastrointestinal Disease

Severe Potential Hazard, Moderate plausibility

Applies to: Esophageal Disease, Esophageal Obstruction, Peptic Ulcer, Gastroesophageal Reflux Disease

Etidronate administered orally may cause local irritation of the upper gastrointestinal mucosa. Its use is contraindicated in patients with esophageal abnormalities that delay esophageal emptying such as achalasia or strictures. Etidronate should be used with caution in patients with active upper gastrointestinal problems, such as Barrett's esophagus, dysphagia, gastritis, duodenitis, ulcers, etc, as cases of erosions, bleeding and perforation have been reported. Patients should be instructed to discontinue treatment immediately and seek medical attention if they develop dysphagia, retrosternal pain, or new or worsening heartburn.

Moderate

Etidronate (Includes Didronel IV) ↔ Renal Dysfunction

Moderate Potential Hazard, High plausibility

Applies to: Renal Dysfunction

Etidronate is eliminated intact by the kidney. There is no experience to specifically make recommendations in patients with impaired renal function. Etidronate dosage should be reduced when reductions in glomerular filtration rates are present. Patients with renal impairment should be closely monitored.

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.
Unknown No information available.
