ADENURIC tablets are used to treat gout, which is associated with an excess of a chemical called uric acid (urate) in the body. In some people, the amount of uric acid builds up in the blood and may become too high to remain soluble. When this happens, urate crystals may form in and around the joints and kidneys. These crystals can cause sudden, severe pain, redness, warmth and swelling in a joint (known as a gout attack). Left untreated, larger deposits called tophi (TOE-FI) may form in and around joints. These tophi may cause joint and bone damage.
ADENURIC works by reducing uric acid levels. Keeping uric acid levels low by taking ADENURIC once every day stops crystals building up, and over time it reduces symptoms. Keeping uric acid levels sufficiently low for a long enough period can also shrink tophi.

Do not take ADENURIC if you are:
- If you are allergic (hypersensitive) to febuxostat, the active ingredient of ADENURIC, or any of the other ingredients in these tablets.
Take special care with ADENURIC
Tell your doctor before you start to take this medicine:
- If you have or have had heart failure or heart problems
- If you are being treated for high uric acid levels as a result of cancer disease or Lesch-Nyhan syndrome (a rare inherited condition in which there is too much uric acid in the blood)
- If you have thyroid problems
If you are having a gout attack at the moment (a sudden onset of severe pain, tenderness, redness, warmth and swelling in a joint), wait for the gout attack to subside before first starting treatment with ADENURIC.
For some people, gout attacks may flare up when starting certain medicines that control uric acid levels. Not everyone gets flares, but you could get a flare-up even if you are taking ADENURIC, and especially during the first weeks or months of treatment. It is important to keep taking ADENURIC even if you have a flare, as ADENURIC is still working to lower uric acid. Over time, gout flares will occur less often and be less painful if you keep taking ADENURIC every day.
Your doctor will often prescribe other medicines, if they are needed, to help prevent or treat the symptoms of flares (such as pain and swelling in a joint).
Your doctor may ask you to have blood tests to check that your liver is working normally.
Taking other medicines
Please tell your doctor or pharmacist if you are taking, or have recently taken, any other medicines, including medicines obtained without a prescription.
It is especially important to tell your doctor or pharmacist if you are taking medicines containing any of the following substances as they may interact with ADENURIC and your doctor may wish to consider necessary measures:
- Mercaptopurine (used to treat cancer)
- Azathioprine (used to reduce immune response)
- Theophylline (used to treat asthma)
Taking ADENURIC with food and drink
The tablets should be taken by mouth and can be taken with or without food.
Pregnancy and breast-feeding
It is not known if ADENURIC may harm your unborn child. Tell your doctor if you think you are pregnant or if you are planning to become pregnant as ADENURIC should not be used during pregnancy. It is not known if ADENURIC may pass into human breast milk. You should not use ADENURIC if you are breast feeding, or if you are planning to breastfeed.
Driving and using machines
No studies on the effects of ADENURIC on the ability to drive and use machines have been performed. However, you should be aware that you may experience dizziness, sleepiness and numbness or tingling sensation during treatment and should not drive or operate machines if affected.
Important information about some of the ingredients of ADENURIC
ADENURIC tablets contain lactose (a type of sugar). If you have been told that you have an intolerance to some sugars contact your doctor before taking this medicine.
Always take ADENURIC exactly as your doctor has told you. You should check with your doctor or pharmacist if you are not sure.
ADENURIC is available as either an 80 mg tablet or a 120 mg tablet. Your doctor will have prescribed the strength most suitable for you.
- The usual dose is one tablet daily. The back of the blister pack is marked with the days of the week to help you check that you have taken a dose each day.
- The tablets should be taken by mouth and can be taken with or without food.
It is important that you do not stop taking ADENURIC unless your doctor tells you to.
Continue to take ADENURIC every day even when you are not experiencing gout flare or attack.
If you take more ADENURIC than you should
In the event of an accidental overdose ask your doctor what to do, or contact your nearest accident and emergency department.
If you forget to take ADENURIC
If you miss a dose of ADENURIC take it as soon as you remember unless it is almost time for your next dose, in which case miss out the forgotten dose and take your next dose at the normal time. Do not take a double dose to make up for a forgotten dose.
If you stop taking ADENURIC
Do not stop taking ADENURIC without the advice of your doctor even if you feel better. If you stop taking ADENURIC your uric acid levels may begin to rise and your symptoms may worsen due to the formation of new crystals of urate in and around your joints and kidneys.
If you have any further questions on the use of this product, ask your doctor or pharmacist.
