Brand Information
Sovaldi (SOFOSBUVIR)
WARNING: RISK OF HEPATITIS B VIRUS REACTIVATION IN PATIENTS COINFECTED WITH HCV AND HBV
Test all patients for evidence of current or prior hepatitis B virus (HBV) infection before initiating treatment with SOVALDI. HBV reactivation has been reported in HCV/HBV coinfected patients who were undergoing or had completed treatment with HCV direct acting antivirals and were not receiving HBV antiviral therapy. Some cases have resulted in fulminant hepatitis, hepatic failure, and death. Monitor HCV/HBV coinfected patients for hepatitis flare or HBV reactivation during HCV treatment and post-treatment follow-up. Initiate appropriate patient management for HBV infection as clinically indicated

2CONTRAINDICATIONS

3ADVERSE REACTIONS
The following serious adverse reactions are described below and elsewhere in the labeling:
- Serious Symptomatic Bradycardia When Coadministered with Amiodarone
3.1Clinical Trials Experience
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 practice.
When SOVALDI is administered with ribavirin or peginterferon alfa/ribavirin, refer to the respective prescribing information for a description of adverse reactions associated with their use.
3.2Postmarketing Experience
The following adverse reactions have been identified during post approval use of SOVALDI. Because postmarketing reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
4OVERDOSAGE
The highest documented dosage of sofosbuvir was a single dose of sofosbuvir 1200 mg (three times the recommended dosage) administered to 59 healthy subjects. In that trial, there were no untoward effects observed at this dosage level, and adverse events were similar in frequency and severity to those reported in the placebo and sofosbuvir 400 mg treatment groups. The effects of higher dosages are not known.
No specific antidote is available for overdose with SOVALDI. If overdose occurs, the patient must be monitored for evidence of toxicity. Treatment of overdose with SOVALDI consists of general supportive measures including monitoring of vital signs as well as observation of the clinical status of the patient. A 4-hour hemodialysis session removed 18% of the administered dose.
