Mechanism of Potassium chloride-Clomipramine Interaction (Severity Level: Major)
Increased risk of GI mucosal injury/bleeding risk Click to Show/Hide Mechanism Graph
Drug Name		Potassium chloride				Clomipramine
Mechanism		GI mucosal injury/bleeding risk				Decrease gastrointestinal motility
Key Mechanism Factor 1
		Factor Name		Gastrointestinal toxicity
		Factor Description		The risk and severity of gastrointestinal toxicity, including inflammation, bleeding, ulceration, and perforation, increases when drugs with gastrointestinal mucosal irritant effects are combined.
Mechanism Description		Increased risk of GI mucosal injury/bleeding risk by the combination of Potassium chloride and Clomipramine

Recommended Action
Management		The use of oral solid formulations of potassium chloride is considered contraindicated in patients receiving agents with anticholinergic properties at sufficient doses to exert anticholinergic effects. A liquid formulation of potassium chloride should be considered. Patients prescribed a solid oral formulation should be advised to discontinue potassium therapy and contact their physician if they experience potential symptoms of upper GI injury such as severe vomiting, abdominal pain, distention, and gastrointestinal bleeding.
