WARNINGS AND PRECAUTIONS
Bradycardia with amiodarone coadministration: Serious symptomatic
bradycardia may occur in patients taking amiodarone and SOVALDI in
combination with another direct acting antiviral (DAA), particularly in patients
also receiving beta blockers, or those with underlying cardiac comorbidities
and/or advanced liver disease. Coadministration of amiodarone with
SOVALDI in combination with another DAA is not recommended. In patients
without alternative, viable treatment options, cardiac monitoring
is recommended.
Use with other drugs containing sofosbuvir is not recommended

follow the dosage recommendations in the table above.
SOVALDI in combination with ribavirin for 24 weeks can be considered for patients
with genotype 1 infection who are interferon ineligible.

Patient Information:
PATIENT COUNSELING INFORMATION
Advise the patient to read the FDA-approved patient labeling (Patient Information).
Serious Symptomatic Bradycardia
When Coadministered with Amiodarone and Another HCV Direct Acting Antiviral
Advise patients to seek medical evaluation immediately for symptoms of
bradycardia such as near-fainting or fainting, dizziness or lightheadedness,
malaise, weakness, excessive tiredness, shortness of breath, chest pain,
confusion or memory problems
Pregnancy
Advise patients to avoid pregnancy during combination treatment with SOVALDI
and ribavirin or SOVALDI and peginterferon and ribavirin. Inform patients
to notify their health care provider immediately in the event of a pregnancy
Drug Interactions
Advise patients that SOVALDI may interact with some drugs; therefore, patients
should be advised to report the use of any prescription, non-prescription
medication or herbal products to their healthcare provider
.
Hepatitis C Virus Transmission
Inform patients that the effect of treatment of hepatitis C infection on transmission
is not known, and that appropriate precautions to prevent transmission
of the hepatitis C virus during treatment or in the event of treatment failure
should be taken.
Important Information on Co-Administration with Ribavirin or Peginterferon and Ribavirin
Advise patients that the recommended regimen for patients with genotype 1 or 4 HCV
infection is SOVALDI administered in combination with peginterferon alfa and ribavirin
and the recommended regimen for patients with genotype 2 or 3 HCV infection is
SOVALDI administered in combination with ribavirin. If peginterferon and/or ribavirin are
permanently discontinued, SOVALDI should also be discontinued.
Pharmacology/ Pharmacokinetics:
CLINICAL PHARMACOLOGY
1. Mechanism of Action
Sofosbuvir is a direct-acting antiviral agent against the hepatitis C virus
2. Pharmacokinetics
Absorption
The pharmacokinetic properties of sofosbuvir and the predominant circulating
metabolite GS-331007 have been evaluated in healthy adult subjects and in
subjects with chronic hepatitis C.
Relative to healthy subjects administered sofosbuvir alone (N=272), the sofosbuvir
AUC0-24 was 60% higher; and GS-331007 AUC0-24 was 39% lower, respectively,
in HCV-infected subjects. Sofosbuvir and GS-331007 AUCs are near dose
proportional over the dose range of 200 mg to 1200 mg
Interaction with Food:
To be taken with food
Pregnancy and lactation:
USE IN SPECIFIC POPULATIONS
1 Pregnancy
Pregnancy Category B:
There are no adequate and well-controlled studies with SOVALDI in pregnant women.
Because animal reproduction studies are not always predictive of human response,
SOVALDI should be used during pregnancy only if the potential for benefit justifies
the potential risk to the fetus
2. Nursing Mothers
It is not known whether SOVALDI and its metabolites are present in human breast milk.
If SOVALDI is administered in a regimen containing ribavirin, the information for ribavirin
with regard to nursing mothers also applies to this combination regimen.
Refer to the ribavirin prescribing information for more information on use in nursing
mothers.
3.Pediatric Use
Safety and effectiveness of SOVALDI in children less than 18 years of age have not
been established.
4. Geriatric Use
SOVALDI was administered to 90 subjects aged 65 and over. The response rates
observed for subjects over 65 years of age were similar to that of younger subjects
across treatment groups. No dosage adjustment of SOVALDI is warranted in geriatric
patients
