Counselling customers at risk of the triple whammy effect at community pharmacies - A feasibility study.

The combination of diuretics, angiotensin-converting enzyme inhibitors (ACE-i)/angiotensin II receptor blockers (ARBs) and non-steroidal anti-inflammatory drugs (NSAID) involves a risk of acute renal failure known as the triple whammy effect (TWE). NSAID can be provided by prescription or over the counter (OTC) and community pharmacies counsel on this medication every day to contribute to medication safety. The objective of this study is to test the feasibility of an intervention where community pharmacies identify and counsel customers at risk of the TWE.
