Ibuprofen: The Anti-Inflammatory That Puts Your Kidneys in Check
Ibuprofen, a nonsteroidal anti-inflammatory drug (NSAID) widely used for muscle pain, migraines, and inflammation, is a double-edged swo:rd. Although effective in the short term, overuse can reduce blood flow to the kidneys, impairing their ability to filter blood.
This can trigger acute kidney failure, especially in people with risk factors such as diabetes, hypertension, or dehydration. Nephrologists warn that taking ibuprofen at high doses (more than 2,400 mg per day) or for prolonged periods significantly increases this risk. Symptoms of kidney damage, such as leg swelling, fatigue, or changes in urine, may go unnoticed at first.
To minimize risks, use ibuprofen only at the recommended dose (generally 200–400 mg every 6–8 hours, not to exceed 3,200 mg per day) and for the shortest possible time.
Be sure to stay hydrated, as dehydration worsens kidney damage.
If you frequently require pain relief, consult a doctor to explore alternatives, such as physical therapy or medications that are less aggressive for the kidneys. Keep track of how often you use ibuprofen and pay attention to signs such as cloudy urine or decreased urine output, which require immediate attention.
Paracetamol: The Deceptively Safe Pain Reliever
Paracetamol, known for relieving minor aches and fever, is perceived as a gentler option than NSAIDs, but it is not without risks. Although its primary impact is on the liver, chronic use or use at high doses (more than 4,000 mg per day) can damage the renal tubules, the structures that filter the blood.
