You’ve just picked up a prescription and noticed the letters “QPM” scribbled next to the instructions. You pause, wondering if you’re supposed to take it now or later.
Let’s find out what it means.
QPM stands for "quaque post meridiem," a Latin phrase that translates to "every evening" or "every afternoon." It’s a common abbreviation used in medical settings, especially when giving instructions about when to take a treatment or carry out a routine.
In the past, Latin was the standard language of science and medicine. That’s why many medical abbreviations, like QPM, still come from Latin terms. Even today, healthcare professionals continue to use these abbreviations for quick and clear communication.
QPM is usually seen in written instructions, such as a doctor’s note or a patient chart. It tells the reader that a certain action should happen once each evening. Most professionals recognize QPM instantly, but patients may not always know what it means without asking.
In daily healthcare practice, QPM is used to tell someone to do something every evening. You might find it in medication schedules, hospital discharge summaries, or even in notes written by nurses or doctors.
Here are a few simple examples of how QPM might appear:
Using QPM helps save space and time in documentation. However, many healthcare providers now prefer to write out full instructions to avoid confusion, especially for people who aren't familiar with medical terms.
Understanding terms like QPM can make healthcare instructions much clearer. This is especially important for people who manage their own care at home, such as older adults or those with long-term conditions.
According to the British Heart Foundation, it’s essential to take some medications at night because “your body clock can influence how well medications work. For example, you produce more cholesterol at night.”
It’s also useful for:
Knowing what QPM means can prevent mistakes and make it easier to follow daily instructions. If there’s ever any doubt, it’s always okay to ask a professional to explain.
QPM is still known by many professionals, but it’s used less often now. Most healthcare providers prefer to write full instructions like “take every evening” instead of using short forms.
This shift helps prevent confusion and keeps patients safe. Many encourage using clear language to avoid mistakes. Today, many clinics and hospitals choose plain words so that patients can better understand their care.
Medical professionals use many short forms to describe when something should happen during the day. Here’s a quick look at how QPM compares to other common time-related abbreviations:
These terms help make documentation faster, but they’re also a reason why patients should feel free to ask questions if anything is unclear.
QPM usually means the dose is meant for the evening hours, not the early afternoon. Taking it earlier might reduce how well it works, especially if it’s designed to match your body’s natural rhythm later in the day. If you're not sure what time to take it, it's best to check with your doctor or pharmacist.
Taking a QPM dose in the morning might change how it affects your body, especially if it’s meant to work overnight. In many cases, there may be no serious problems, but it depends on what you're taking and why. Don’t take another dose in the evening, one dose per day is still one dose. If you’re unsure, call your doctor for advice.
If you miss your evening dose, don’t double up the next day. Just skip the missed dose and continue with your regular schedule unless your doctor says otherwise. Taking two doses too close together can lead to unwanted effects. If you often forget, try setting a reminder on your phone or linking it to your evening routine, like brushing your teeth.
