An anti-inflammatory painkiller (NSAID)
Tiaprofenic acid
An anti-inflammatory painkiller used for pain and swelling in joint conditions, with a known risk of bladder irritation.
What is Tiaprofenic acid?
Tiaprofenic acid is an anti-inflammatory painkiller, a type of medicine known as an NSAID. It is used to ease pain and swelling in joint conditions such as osteoarthritis and rheumatoid arthritis. It works by reducing the chemicals in the body that cause inflammation and pain. An important and well-recognised point with this particular NSAID is a risk of bladder irritation or cystitis, so if you develop urinary symptoms such as pain passing urine, needing to go more often, or blood in the urine, you should stop taking it and seek advice. Like other NSAIDs, it can also upset the stomach and is used with care in some people.
Education and reference only. This is a plain-language guide to Tiaprofenic acid — it deliberately contains no doses. Doses depend on the person, the brand and the reason for treatment, and belong with your prescriber. Always check the BNF, the product labelling (SmPC) and follow medical advice.
What it is
Tiaprofenic acid is a non-steroidal anti-inflammatory drug, or NSAID, taken by mouth to relieve pain and reduce inflammation. It is used in conditions affecting the joints, such as osteoarthritis, where wear of the joints causes pain and stiffness, and rheumatoid arthritis, where the joints become inflamed. It belongs to the same broad family as ibuprofen and naproxen. What sets it apart is a recognised link with bladder problems, so it is used with awareness of that risk and is not usually a first choice when other NSAIDs would do.
How it works
Tiaprofenic acid works by blocking enzymes in the body that produce chemicals called prostaglandins, which cause pain, swelling and inflammation at sites of injury or in inflamed joints. By lowering these chemicals, it reduces pain and stiffness and helps inflamed joints feel and move better. The same action that reduces inflammation, however, also reduces protective prostaglandins in the stomach lining and affects the kidneys, which is why NSAIDs can cause stomach and kidney side effects. Why this particular NSAID is linked with bladder irritation is not fully understood, but the connection is well recognised.

Advantages & disadvantages of Tiaprofenic acid
Advantages
- An effective anti-inflammatory painkiller for pain and swelling in joint conditions.

Practical use
Good to know
The single most important thing to know about tiaprofenic acid is its recognised link with bladder irritation and cystitis: if you develop urinary symptoms such as pain or burning when passing urine, needing to pass urine more often or urgently, or blood in the urine, you should stop taking it and seek medical advice. Apart from this, it shares the usual NSAID cautions: it can irritate the stomach and, rarely, cause ulcers or bleeding, so it is taken with or after food, and it can affect the kidneys, blood pressure and the heart, especially with long-term use or in older people. It is generally used at the lowest helpful amount for the shortest time that controls symptoms. Tell your prescriber about other medicines, as NSAIDs interact with several, and about any history of stomach, kidney, heart or bladder problems.
Who should not take it / use with caution
- People with a current or past stomach or duodenal ulcer or bleeding should usually not take it.
- People who have had urinary or bladder problems with it before, or ongoing bladder symptoms, should not take it.
- People with severe heart, kidney or liver problems should avoid it, and it is used with care in older people.
- People who have had asthma, wheezing or an allergic reaction to aspirin or other NSAIDs should not take it.
Monitoring
- Watching for urinary or bladder symptoms, with advice to stop and seek help if they occur.
- Reviewing for stomach symptoms, and checking blood pressure and kidney function with longer use.
- Using the lowest helpful amount for the shortest time and reviewing the need for it.
Side effects
- Bladder irritation or cystitis, with symptoms such as pain passing urine, going more often, or blood in the urine, which means stopping and seeking advice.
- Indigestion, stomach pain or nausea, and rarely stomach ulcers or bleeding.
- Headache, dizziness, or fluid retention; with longer use, effects on the kidneys, blood pressure and heart.
Key interactions
- It can increase the bleeding risk when taken with anticoagulants such as warfarin or with aspirin.
- It can reduce the effect of some blood-pressure medicines and affect the kidneys when combined with certain water tablets.
- Taking it with other NSAIDs, steroids or certain antidepressants raises the risk of stomach problems and bleeding.
Available as: Tablets taken by mouth.
