Adenuric side effects
Summary of the security profile
The most commonly reported adverse reactions in clinical studies (4, 072 patients treated with at least one dose of 10 mg to 300 mg) and post-marketing experience in gout patients were droplet attacks, abnormal liver function, diarrhea, nausea, headache, rashes and edema. These adverse effects were generally of mild or moderate severity. Few serious hypersensitivity reactions to febuxostat, some of which were associated with systemic symptoms, were observed after marketing.
Tabulated list of adverse effects
Frequent (≥ 1/100 to <1/10), infrequent (≥ 1/1000 to <1/100), and rare (≥ 1/10 000 to <1/1000) adverse reactions in treated patients by febuxostat are mentioned below. Frequencies are based on studies and after marketing in patients with gout.
In each frequency group, the adverse effects are presented in order of decreasing severity.

Description of specific adverse events
Rare severe hypersensitivity reactions to febuxostat, including Stevens-Johnson syndrome, toxic epidermal necrolysis (Lyell syndrome), and anaphylactic reaction / shock have been observed post-marketing. Stevens-Johnson syndrome and toxic epidermal necrolysis are characterized by a progressive skin rash, accompanied by bubbles or mucosal lesions and eye irritation. Hypersensitivity reactions to febuxostat may be associated with the following symptoms: skin reactions characterized by an infiltrated maculopapular rash, generalized or exfoliative rash, but also cutaneous lesions, facial edema, fever, abnormalities of the skin. blood tests such as thrombocytopenia and eosinophilia, and involvement of a single organ or multiple organ (liver and kidneys including tubulointerstitial nephritis) (see Warnings and Precautions for Use section ).
The gout attacks were frequently observed shortly after the start of treatment and during the first few months. Subsequently, the frequency of gout attacks decreases over time. Prophylaxis of gout flares is recommended (see sections Posology and method of administration and Warnings and precautions for use ).
Tumor Lysis Syndrome
Tolerance Profile Summary
In the pivotal FLORENCE (FLO-01) phase 3, randomized, double-blind study, comparing febuxostat to allopurinol (346 patients undergoing chemotherapy for hematologic malignancies and at intermediate risk or at high risk of TLS), only 22 (6.4%) of all patients experienced adverse events, ie 11 (6.4%) patients in each treatment group. The majority of adverse events were mild or moderate.
In total, the FLORENCE study does not show any particular problem of tolerance in addition to that already known with ADENURIC in the treatment of gout, with the exception of the following three adverse effects (listed above in Table 1). ).
Heart conditions:
Uncommon: left branch block, sinus tachycardia.
Vascular disorders:
Uncommon: haemorrhage.
Reporting of suspected adverse reactions
The reporting of suspected adverse reactions after authorization of the drug is important. It allows continuous monitoring of the benefit / risk ratio of the drug. Health professionals report any suspected adverse reactions via the national reporting system - see Annex V.
