Painkillers for people with a kidney infection

BMJ Group Medical Reference

Kidney infections can be painful, and your doctor may suggest you take painkillers to help. If you're in a lot of pain, make sure you tell your doctor. He or she can prescribe a stronger painkiller or a higher dose.


Paracetamol reduces pain and fever. You can buy it from a pharmacy. Your doctor may recommend it if you're being treated for a kidney infection at home. But there hasn't been any research saying how much it helps people with a kidney infection.

Taking too much paracetamol can cause serious liver damage. [32] Be careful not to take more than the recommended dose printed on the packet.

Nonsteroidal anti-inflammatory drugs

Nonsteroidal anti-inflammatory drugs ( NSAIDs) are drugs that reduce pain and inflammation. Aspirin and ibuprofen (brand name Nurofen) are both NSAIDs. You can buy these drugs from a pharmacy or get larger doses on prescription from your doctor.

There isn't any good research on how well NSAIDs work for people with kidney infections. However, a side effect of NSAIDs is that they sometimes cause kidney damage. If you have a kidney infection, your doctor may recommend that you avoid these drugs or only take a low dose. [33]

Urinary analgesics

In some countries, doctors use drugs called urinary analgesics to reduce pain caused by urinary tract infections. These are tablets that relax the muscles of the urinary tract.

Three types of drugs are used: flavoxate (brand name Urispas), pargeverine, and phenazopyridone. Only flavoxate is available in the UK. It's usually used for people with a type of incontinence called urge incontinence.

There isn't any good research to say whether these drugs work to relieve pain caused by kidney infections.



Inflammation is when your skin or some other part of your body becomes red, swollen, hot, and sore. Inflammation happens because your body is trying to protect you from germs, from something that's in your body and could harm you (like a splinter) or from things that cause allergies (these things are called allergens). Inflammation is one of the ways in which your body heals an infection or an injury.
