I usually tell people to rinse their plates before loading them in the dishwasher.

Totally depends on the situation. In the real world medicine is both an art and a science. I usually draw the line on controlled substance cascades. If some one is getting so gorked out on benzos/muscle relaxers/hypnotics they need stimulants dosed multiple times a day, then we have a problem. A long and illustrious history of red flags will usually warrant a doctor call to verify medical rationale behind the cascade. If I cant resolve the issue or get a satisfactory explanation on a red flagger, I return the cs orders

I have never heard this term before. Who said Student Doctors board wasn't educational?

Hmm interesting. I asked because my mother was a victim of it and I decided to explain her situation in my personal statement for pharmacy school. I just wasn't sure how to make a difference when it comes to that.

Same here, first time learning about the term and now I know it's meaning, so I share with examples (quoted under Fair Use License for Educational Purpose):

The Prescribing Cascade
Printer-friendly version
Any new symptom in an older adult should be considered a drug side effect until proven otherwise. Unfortunately, medicines are often overlooked by clinicians as a likely cause of new symptoms in older adults. A common mistake is to treat the symptom by adding a new drug. Sometimes, this new drug also causes another side effect, which can then trigger adding yet another new drug. This sequence of events is known as the "prescribing cascade." Examples are described below.

Increased incidence of levodopa therapy following metoclopramide use

In one of the early articles about the prescribing cascade, Avorn and colleagues used the New Jersey Medicaid database to determine whether there was an increase in use of anti-parkinsonian therapy in older persons (65 years and over) taking metoclopramide hydrochloride. Metoclopramide causes side-effects that mimic Parkinson’s disease. They found that metoclopramide users were three times more likely to begin use of a levodopa-containing medication compared with nonusers.

Users of nonsteroidal anti-inflammatory drugs (NSAIDs) are more likely to be started on medications for high blood pressure

NSAID medications can cause sodium and water retention, which increases blood pressure. In this study, users of NSAIDs were 66% more likely to be started on medicine for hypertension, and higher doses were more likely to trigger blood pressure medicines than low doses.

Increased use of "overactive bladder" drugs in patients taking cholinesterase inhibitors for Alzheimer’s disease

In this study, older adults receiving a cholinesterase inhibitor (e.g. donepezil) for Alzheimer’s disease were over 50% more likely to be receiving a bladder anticholinergic drug (e.g. oxybutynin, tolterodine) than older adults not taking these drugs. Cholinesterase inhibitors can cause urinary incontinence as a side effect, but this symptom is often not recognized by the prescriber and the symptom is treated with another drug.
