The signs a colleague can actually see
A plain look at the observable signs of impairment in a pharmacy colleague, and how to separate what you see from what you guess.
Published

In a pharmacy, colleagues work close together for long shifts. That closeness means changes in behavior are often noticed first by the people standing at the next bench, not by managers or boards. Knowing which signs are observable, and which are only guesses, helps a colleague respond carefully.
What can you actually observe at work?
Observable signs fall into a few broad categories described in clinical literature, including material from Mayo Clinic and government sources on substance use. Physical signs can include bloodshot eyes, dilated or constricted pupils, tremors, unsteady movement, frequent nosebleeds, or noticeable changes in grooming and weight. Behavioral signs include mood swings, irritability, withdrawal from conversations, or unusual defensiveness when asked ordinary questions.
None of these signs is proof of anything on its own. Fatigue, illness, grief, and medication side effects can look similar. What matters is a pattern: a cluster of signs that persists over weeks and that represents a change from how the person previously worked.
Which job performance changes matter most?
In pharmacy specifically, certain performance changes carry weight because of the safety context. Frequent counting errors, missing inventory, discrepancies in controlled substance logs, unusual complaints from patients about short fills, and reluctance to take breaks or hand over tasks are all documented warning signs in professional literature on impaired practitioners.
Other workplace signs include working through lunch, volunteering for tasks that provide access to controlled substances, refusing to let others verify their work, and an increase in typos or mislabels. A single late shift can explain any one of these. Repetition across weeks is the signal worth noting.
How do you separate observation from judgment?
This is the discipline that protects both you and your colleague. An observation is what a camera would record: "the log shows three discrepancies this week" or "she has been late four times in two weeks." An inference is the story attached to it: "she must be using." Impairment has many causes, including physical illness, mental health conditions, family crisis, and burnout. Publications such as SAMHSA emphasize that substance use disorders are treatable health conditions, not character verdicts.
A useful habit is to write down what you see, factually, with dates. This record helps if you later report to a supervisor or a state program, and it keeps your own thinking anchored to facts rather than suspicion.
What should you do, and not do, with what you notice?
Most states operate recovery-friendly programs for pharmacists, often called pharmacist recovery programs or professional health programs, which receive reports and arrange monitoring and treatment. Many boards of pharmacy allow self-referral or peer referral. In settings where a pharmacist's impairment could harm a patient, reporting obligations may apply; several states require reporting suspected impairment to the board or program. Checking your own state's rules, or asking a supervisor or human resources office confidentially, is a reasonable first step.
What generally does not help is confronting a colleague with accusations, conducting your own interrogation, or covering for errors without reporting them. Covering up removes the natural pressure that leads people into treatment, and it can make you complicit in a medication error.
Why early recognition matters
Impairment in a pharmacy is a patient safety issue first, but for the impaired pharmacist it is also a survivable condition. Recovery rates among monitored health professionals who complete treatment and monitoring programs are reported to be high in the professional literature. Colleagues who notice early, document what they see, and route concerns through the proper channel often shorten the time between the onset of a problem and the start of recovery.
You do not need to diagnose anyone. You only need to notice, record, and pass the concern to someone equipped to act. That is the limit of a colleague's role, and it is enough.
