Pain medicines are among the most common medicines in the world. Whether it be headache, backache, joint pain or period cramps, many people don’t think twice before reaching for OTC pain relief tablets. These drugs work very well when taken as prescribed but if you take them too often or over a long period of time, they can have unexpected effects on your kidneys.
So can pain killers slowly kill your kidneys?
The answer is yes– especially if taken regularly, in high doses, or without medical supervision.
## How do the kidneys work?
Your kidneys filter your blood to remove excess fluid and waste products. They also regulate blood pressure, balance electrolytes and produce hormones that help make red blood cells and keep bones strong.
Some medicines, including some pain medicines, may affect how well your kidneys work. Your kidneys filter everything that goes into your blood.
Can Painkillers Cause Kidney Damage? Understanding the Risks
The most common painkillers linked to kidney damage are
Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)
They include medicines commonly used for pain, fever and inflammation.
NSAIDs are safe for most healthy adults when occasional use is as directed. But long-term or heavy use can restrict blood flow to the kidneys, making it harder for them to do their jobs.
It is especially risky when patients are left to self-manage their chronic pain without medical supervision.
How Do Painkillers Harm the Kidney?
NSAIDs work by blocking the production of chemicals called prostaglandins that normally help keep blood flowing to the kidneys. If prostaglandin levels are reduced there may be a reduction in renal blood flow.
This can result over time in:
- Acute Renal Failure
- Chronic kidney disease (CKD)
- Fluid overload
- Hypertension
WHO IS AT HIGHEST RISK?
Painkillers don’t necessarily cause kidney problems. However, people who:
Chronic Kidney Disease.
- Diabetes,
- High Blood Pressure.
- Age > 60 years
- Dehydration
- Heart Disease
