Chapter 2: Habit #1 — Taking Painkillers Too Often

Painkillers are among the most commonly used medications in everyday life.

People take them for headaches, back pain, muscle injuries, menstrual cramps, dental pain, arthritis, and many other conditions.

The problem is not that every painkiller damages the kidneys.

The concern is particularly relevant to nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen and naproxen when they are used frequently, at high doses, or in people with certain medical conditions.

These medications can reduce the production of substances called prostaglandins. Some prostaglandins help maintain blood flow to the kidneys. Under certain circumstances, reducing them can decrease kidney blood flow and contribute to acute kidney injury.

The risk can become greater when NSAIDs are combined with dehydration, low blood pressure, heart failure, or existing kidney disease.

Long-term heavy use can also contribute to chronic kidney problems in some people.

This does not mean that someone should panic after taking an occasional recommended dose of ibuprofen.

For many healthy adults, short-term use at the recommended dose may be appropriate.

The danger comes from treating painkillers as something that can be taken indefinitely without considering the cause of the pain or the person's medical history.

Someone who repeatedly needs pain medication should ask an important question:

Why does the pain keep coming back?

Persistent headaches, back pain, joint pain, or other chronic symptoms may require evaluation rather than increasingly frequent medication.

People with kidney disease, high blood pressure, heart disease, dehydration, or certain other conditions should discuss NSAID use with a healthcare professional.

Other medications can also affect kidney function, so anyone taking several drugs regularly should make sure their doctor or pharmacist knows what they are using.

The safest rule is simple: follow the recommended dose, avoid unnecessary prolonged use, and seek medical advice when pain becomes a recurring problem.
