Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.

SPORANOX® has been associated with rare cases of serious hepatotoxicity, including liver failure and death. Some of these cases had neither pre-existing liver disease nor a serious underlying medical condition. If clinical signs or symptoms develop that are consistent with liver disease, treatment should be discontinued and liver function testing performed. The risks and benefits of SPORANOX® use should be reassessed.

Adverse Events In The Treatment Of Systemic Fungal Infections

Adverse event data were derived from 602 patients treated for systemic fungal disease in U.S. clinical trials who were immunocompromised or receiving multiple concomitant medications. Treatment was discontinued in 10.5% of patients due to adverse events. The median duration before discontinuation of therapy was 81 days (range: 2 to 776 days). The table lists adverse events reported by at least 1% of patients.

Vascular Disorders: hypotension

Post-Marketing Experience

Adverse drug reactions that have been first identified during post-marketing experience with SPORANOX® (all formulations) are listed in the table below. Because these reactions are reported voluntarily from a population of uncertain size, reliably estimating their frequency or establishing a causal relationship to drug exposure is not always possible.

Table 4: Postmarketing Reports of Adverse Drug Reactions

Blood and Lymphatic System Disorders: Leukopenia, neutropenia, thrombocytopenia
Immune System Disorders: Anaphylaxis; anaphylactic, anaphylactoid and allergic reactions; serum sickness; angioneurotic edema
Nervous System Disorders: Peripheral neuropathy, paresthesia, hypoesthesia, tremor
Eye Disorders: Visual disturbances, including vision blurred and diplopia
Ear and Labyrinth Disorders: Transient or permanent hearing loss
Cardiac Disorders: Congestive heart failure
Respiratory, Thoracic and Mediastinal Disorders: Pulmonary edema, dyspnea
Gastrointestinal Disorders: Pancreatitis, dysgeusia
Hepatobiliary Disorders: Serious hepatotoxicity (including some cases of fatal acute liver failure), hepatitis

There is limited information on the use of SPORANOX® during pregnancy. Cases of congenital abnormalities including skeletal, genitourinary tract, cardiovascular and ophthalmic malformations as well as chromosomal and multiple malformations have been reported during post-marketing experience. A causal relationship with SPORANOX® has not been established.
