can antibiotics cause kidney pain | Important Points

Antibiotics are one of the most commonly prescribed classes of drugs that are used to treat bacterial infections. While these drugs have been a life-saver for millions of people across the globe, they are not without side effects. One of the possible side effects of antibiotics is kidney pain, which can be severe and persistent. In this article, we will explore the link between antibiotics and kidney pain, and what you can do to mitigate this risk.

What are antibiotics?

Antibiotics are drugs that are designed to kill or inhibit the growth of bacteria, fungi, and other microorganisms that can cause infections in the human body. These drugs work by either directly attacking the bacteria or by weakening their protective cell wall. Antibiotics are prescribed for a wide range of infections, including urinary tract infections, respiratory infections, skin infections, and ear infections.

There are different types of antibiotics, including penicillin, cephalosporins, fluoroquinolones, tetracyclines, macrolides, and aminoglycosides. Each type of antibiotic targets a different group of bacteria and works in a specific way. Depending on the degree of infection and the type of bacteria causing it, the doctor may prescribe a single antibiotic or a combination of antibiotics.

Antibiotics and kidney pain

Kidney pain is a common symptom that can be caused by a variety of factors, including infections, stones, or other underlying medical conditions. In some cases, antibiotics can be a contributing factor to kidney pain.

While antibiotics work by killing bacteria, they can also damage the healthy bacteria that inhabit our gut and urinary tract. This can lead to an imbalance in the microbes that live in our body, which can cause inflammation and infections. In some cases, the inflammation caused by antibiotic use can affect the kidneys, leading to pain and discomfort.

One of the most common types of antibiotics that can cause kidney pain is aminoglycosides. Aminoglycosides are a class of antibiotics that are used to treat serious bacterial infections, such as sepsis and meningitis. These drugs are known to cause kidney damage, especially when used in high doses or for prolonged periods. The kidney damage caused by aminoglycosides can lead to acute kidney injury (AKI), which is a sudden loss of kidney function.

Other types of antibiotics that can cause kidney pain include fluoroquinolones, which are commonly used to treat urinary tract infections and respiratory infections. These drugs can cause inflammation of the kidney, leading to pain and discomfort. In some cases, fluoroquinolones can cause long-term kidney damage, especially when used in elderly patients or those with pre-existing kidney disease.

How to prevent kidney pain from antibiotics

If you are prescribed antibiotics, it is essential to follow the instructions of your doctor and pharmacist carefully. Here are some tips to help prevent kidney pain from antibiotics:

1. Drink plenty of water: Drinking enough fluids can help flush out harmful bacteria and prevent the development of kidney infections. Doctors recommend drinking at least eight glasses of water a day when taking antibiotics.

2. Take your antibiotics as prescribed: It is important to take your antibiotics as prescribed by your doctor. Skipping doses or stopping treatment too early can lead to antibiotic resistance and increase the risk of kidney infections.

3. Avoid NSAIDs: Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen and aspirin, can lead to kidney damage when taken with certain antibiotics. It is best to avoid NSAIDs while taking antibiotics unless your doctor advises otherwise.

4. Be aware of the symptoms: If you develop symptoms such as flank pain, fever, or blood in your urine, it is essential to seek medical attention immediately. These symptoms could indicate a kidney infection or other serious condition.

5. Protect your gut bacteria: Antibiotics can disrupt the balance of gut bacteria, which can lead to inflammation and infections. You can support your gut bacteria by taking probiotics, eating a healthy diet, and avoiding unnecessary antibiotics.


Antibiotics are an essential class of drugs that have saved countless lives since their discovery. However, these drugs are not without side effects, including kidney pain and damage. If you experience kidney pain while taking antibiotics, it is important to seek medical attention immediately. By following the tips in this article, you can reduce the risk of kidney pain and protect your overall health. Remember, antibiotics should always be taken under the guidance of a medical professional, and never used without an appropriate diagnosis.
