Painkillers are a part of everyday life for many Indians. A pill for a headache, joint discomfort, fever, or backache often seems safe, especially since you may get it without a prescription. But using opioids a lot or without supervision can have a silent effect on one of your body’s most important organs: the kidneys.
While pain treatment is crucial, understanding how different medicines interact with renal function can help prevent long-term harm and avoid significant consequences.
The connection between kidney function and painkillers
The kidneys filter waste, control fluid levels and help keep blood pressure in check. Some painkillers disrupt these processes by decreasing blood flow to the kidneys or causing damage, or inflammation, in the kidney’s tissues.
Initially, this damage may not have resulted in any symptoms. But over time, that kind of repeated pressure can cause the kidneys to lose their functionality and for fluid to build up — eventually it may develop into chronic kidney disease.
NSAIDs: Effective but Potentially Harmful
NSAIDs are often used for pain, fever and inflammation. This would include drugs like ibuprofen, diclofenac, naproxen, aceclofenac and related drugs.
These drugs do this by preventing the action of substances that cause inflammation and pain. Unfortunately, it can also diminish blood flow to the kidneys. Over use, high dosage or using NSAIDs during dehydration all can result in the development of sudden kidney injury or lead to progressive damage to the kidneys.
Those with diabetes, high blood pressure, heart disease or existing kidney problems are particularly at risk for NSAID-related kidney damage. Our advice is even short-term use can be dangerous in these cohorts without medical guidance.
Paracetamol: A Relatively Safer Option
Paracetamol is felt to be safer for the kidneys in short term if taken at a therapeutic dose. It has no very inhibitive impact on kidney blood flow and is mostly used for mild to moderate pain or fever.
But “safer” is not synonymous with entirely safe. Overuse, or extended use of it, can affect the liver and dosing should be guided by a doctor — particularly in people who have multiple health concerns.
Combination Painkillers and Hidden Risks
While there are over-the-counter analgesics with multiple substances in them like NSAIDs and muscle relaxants or caffeine, a proper Combogesic pill combines all of these drugs into one. While these combinations will give you fast relief, they are also more likely to lead to an overdose (accidentally) as well as a strain on the kidneys.
People may also inadvertently consume toxic doses — especially when painkillers are taken daily or in combination with other medications that contain an opioid.
Do Herbal Pain Remedies Work and Are They Safe for Kidneys?
Herbal or “natural” remedies for pain are frequently considered safe. Yet some alternative medicines have harmful effects on kidneys, particularly when taken over a long period of time or without quality control.
Nephrologists often encounter unexplained renal insufficiency associated with the long-term ingestion of herbal preparations that are not subject to regulation.
Who’s at Risk for Problems with Painkillers?
Some people should be especially careful, including people with diabetes or high blood pressure, kidney disease, heart conditions or those over 50. Dehydration, many infections and alcohol can further increase kidney risk when the painkillers are taken improperly.
Warning Signs to Look Out for
Kidney strain from painkillers can be subtle. Changes in urine output, swollen feet or face, foamy urine, constant fatigue or increasing blood pressure are all signs the kidneys have begun to be affected. These are ‘red flags’ that should lead to medical rather than self-dispensed treatment.
Using Painkillers Responsibly
What is moderate pain relief, safely done with guidance from a doctor. Pain-killers are not recommended on daily basis without advice, and always keep yourself hydrated. Using a combination of pain medications or any of these drugs during fever, vomiting or dehydration increases risk to the kidneys.
Never Self Medicate Chronic pain should be addressed by a healthcare professional who can help treat the source of the pain — not layer drugs upon drugs.
When It’s Time to See a Nephrologist
If you need painkillers frequently or if it turns out that you have any other health risk factors — such as high blood pressure, diabetes etc. — a nephrologist can help save your kidneys from downward spiral of kidney failure. Early intervention can often head off longer-term damage, and head off future complications such as dialysis.
Conclusion
Painkillers are a good thing when used as prescribed, but not without risk. Unmonitored or overuse can quietly damage the kidneys in time. Knowing which medications are less harmful, using them appropriately and asking for medical advice as necessary can help maintain the health of your kidneys.
