     Decreased renal excretion (Unspecific) Click to Show/Hide Mechanism Graph
      Drug Name Bendroflumethiazide Lithium carbonate
      Mechanism Reduces renal excretion of lithium Lithium salt
      Key Mechanism Factor 1
Factor Name Pharmacokinetics
Factor Description Alters the excretion of the drug, resulting in changes in the plasma concentration of the drug and affecting the pharmacological effects.
      Mechanism Description
  • Decreased renal excretion of Lithium carbonate caused by Bendroflumethiazide 

Recommended Action
      Management Thiazide diuretics should generally not be prescribed to patients receiving lithium unless close monitoring of serum lithium levels and electrolytes can be rendered. Lithium dose reductions may be required. Patients should be advised to notify their physician if they experience potential signs and symptoms of lithium toxicity such as drowsiness, dizziness, muscle weakness, vomiting, diarrhea, thirst, polyuria, tinnitus, tremor, ataxia, and blurred vision.
