Febuxostat
UnsafeThis is a dosing question about a prescription medicine, not a food. Febuxostat dosing must be set by a prescribing clinician.
- Febuxostat is a prescription xanthine oxidase inhibitor used to lower uric acid in gout
- A doctor can tailor the dose to kidney function, liver function, and other medicines
- Regular uric acid blood tests guide whether the dose is working
- Self-selecting a dose can cause side effects such as liver problems, rash, or gout flares
- Starting or changing urate-lowering therapy without medical review can trigger flares
- Cardiovascular history must be assessed before use, as febuxostat carries a warning for heart-related death
Why this cannot be answered as a simple dose
Febuxostat is a prescription medicine that lowers serum uric acid by blocking xanthine oxidase [1]. Typical labeled starting doses are low, commonly 40 mg once daily, with an increase to 80 mg daily if uric acid remains above target after about two weeks [1]. However, the right dose depends on the individual's kidney and liver function, cardiovascular history, current medicines, and how they respond to treatment.
Your reading of 7.0 mg/dL
A uric acid level of 7.0 mg/dL is above the commonly used treatment target of below 6 mg/dL for people with gout, and below 5 mg/dL in those with severe or tophaceous disease [2]. That result alone does not establish a dose. A clinician will usually confirm the level, check kidney function, review for heart disease, and consider whether a flare is ongoing, since urate-lowering therapy is often started with flare prevention such as low-dose colchicine or NSAIDs [2].
Safety points
Febuxostat has a boxed warning about cardiovascular death in people with established heart disease [1]. Liver enzymes and skin reactions should be monitored. Do not start, stop, or change the dose on your own, and do not take leftover medicine from others.
Next step
Book a review with a GP or rheumatologist and bring your recent uric acid, kidney function, and medication list. This is general information, not medical advice.
