(trade name)


Therapeutic: antivirals
Pharmacologic: protease inhibitors
Pregnancy Category: C (alone)
Pregnancy Category: X (for combination with ribavarin and peginterferon alfa)


Treatment of Hepatitis C in combination with other agents (peginterferon alfa and ribavirin) as a total regimen in patients with infection caused by the hepatitis C virus (HCV) genotype 1 (other genotypes may not respond). Not to be used as monotherapy.


Inhibits viral replication; a direct-acting antiviral (DAA).

Therapeutic effects

Clearing of infection with decreased severity and sequelae of HCV.


Absorption: Well absorbed following oral administration, food increases and delays absorption (blood levels are ↑ in HCV-infected patients as compared to non-HCV-infected patients).
Distribution: Unknown.
Protein Binding: >99.9%.
Metabolism and Excretion: Highly metabolized (primarily by CYP3A), eliminated primarily via biliary excretion, 31% excreted unchanged in feces, <1% in urine.
Half-life: HCV-infected patients—41 hr; HCV-uinfected patients —10–13 hr.

Time/action profile (blood levels)

POunknown6–8 hr24 hr


Contraindicated in: Moderate-to-severe hepatic impairment (ribavirin and peginterferon alfa contraindication); Any condition in which peginterferon alpha or ribavirin is contraindicated;Concurrent use of moderate or strong inhibitors or inducers of the CYP3A system (may significant changed in blood levels, effectiveness and risk of toxicity/adverse reactions); Obstetric: Pregnant women and men whose female partners are pregnant (ribavirin contraindication).

Oral (Adults) 150 mg once daily (with peginterferon alfa and ribavirin) for 12 weeks. Treatment with peginterferon alfa and ribavirin may continue for 12–48 wk depending on virologic response.


Capsules: 150 mg

Nursing implications

Nursing assessment

  • Monitor for signs and symptoms of chronic hepatitis C.
  • Assess for rash, especially during first 4 wk of therapy. Monitor mild to moderate rashes for progression, including mucosal signs (oral lesions, conjunctivitis). If rash becomes severe, discontinue simeprevir and monitor until rash resolved.
  • Lab Test Considerations: Use a sensitive assay with a lower limit of quantification of at least 25 IU/mL for monitoring HCV RNA levels during treatment. In treatment wk 4, if HCV RNA ≥25 IU/mL, discontinue simeprevir, peginterferon alfa, and ribavirin. In treatment wk 12, if HCV RNA ≥25 IU/mL,, discontinue peginterferon alfa and ribavirin; simeprevir is completed at wk 12. In treatment wk 24, if HCV RNA ≥25 IU/mL,discontinue peginterferon alfa and ribavirin.
    • A negative pregnancy test must be obtained immediately before beginning therapy and monthly thereafter.
    • May cause ↑ alkaline phosphatase and bilirubin.

Potential Nursing Diagnoses

Risk for infection (Indications)


  • Must be administered in conjunction with ribavirin and peginterferon alfa. If ribavirin and peginterferon alfa are discontinued, simeprevir must be discontinued. If simeprevir is discontinued due to adverse reactions or inadequate response, do not restart simprevir.
  • Oral: Administer once daily with food.

Patient/Family Teaching

  • Instruct patient to take simeprevir with ribavirin and pegainterferon alfa as directed. Take missed doses within 12 hr with food or skip dose and take next scheduled dose; do not double doses. Advise patient to read Patient Information before starting and with each refill in case of changes.
  • Caution patient to wear sunscreen and protective clothing and avoid tanning devices to prevent photosensitivity reaction.
  • Advise patient to notify health care professional if rash or photosensitivity reaction (burning, redness, swelling or blisters on skin; mouth sores or ulcers; red or inflamed eyes like pink eye or conjunctivitis) occurs.
  • Instruct patient to notify health care professional of all Rx or OTC medications, vitamins, or herbal products being taken and consult health care professional before taking any new medications, especially St. Johns Wort.
  • Instruct patient to notify health care professional of all Rx or OTC medications, vitamins, or herbal products being taken and consult health care professional before taking any new medications, especially St. Johns Wort.
  • Advise female patients and male patients with female partners who are pregnant or may become pregnant to use effective contraception due to risks for birth defects and fetal death and avoid breastfeeding. Women and male partners must use 2 forms of non-hormonal contraception during and for at least 6 mo after discontinuation of therapy. Advise women who become pregnant to enroll in the Ribavirin Pregnancy Registry by calling 1-800-593-2214.

Evaluation/Desired Outcomes

  • Decreased severity and sequelae of HCV following treatment with simeprevir, ribavirin, and peginterferon alfa for 12 wk.
    • Patients who are treatment-naïve and prior relapser, including those with cirrhosis, should receive an additional 12 wk of peginterferon alfa and ribavirin for a total of 24 wk.
    • Prior non-responders should receive an additional 36 wk of peginterferon alfa and ribavirin for a total of 48 wk.

Both Sovaldi and Olysio are prescribed in combination with other drugs to complete an antiretroviral treatment for Hepatitis C.
This was in comparison with revenues from Medivir's own pharmaceutical sales of SEK42.5m, of which SEK2.8m was derived from sales of OLYSIO and 39.7m from sales of other pharmaceuticals, in Q32015.
For example, Express Scripts, which manages prescription drug benefits for 85 million people and is the largest pharmacy benefits manager in the US, recently announced it will no longer cover Sovaldi or Olysio (except in limited circumstances).
Medivir AB, Stockholm, Sweden, announced the US FDA has assigned a Priority Review designation to the supplemental New Drug Application (sNDA) for the use of once-daily Olysio (simeprevir) in combination with sofosburvir for 12 weeks treatment of adult patients wit genetype 1 chronic hepatitis C.
Among the four anti-infectives are two oral agents for the treatment of chronic hepatitis C virus infection: simeprevir (Olysio) and sofosbuvir (Sovaldi).
Treatment with Gilead Sciences' sofosbuvir (Sovaldi) costs close to $90,000, while treatment with Johnson & Johnson's simeprevir (Olysio) runs about $66,000, according to the California Technology Assessment Forum, an independent group originally convened by the insurance industry to evaluate costs and benefits of treatments.
The Food and Drug Administration recently approved Janssen Pharmaceutica Inc.'s Olysio (simeprevir) as a hepatitis C treatment and is expected to approve a similar new drug, solos-buvir, later this year.
According to the company, discontinuation of development of JNJ-4178 does not affect the ongoing partnership with Janssen on Olysio (simeprevir), or the existing licensing agreement with Janssen in which simeprevir is included.
OLYSIO /SOVRIAD Hep C sales were down 73% in the quarter to $21 million.
Also, revenues from Medivir's own pharmaceutical sales totalled SEK237.5m for the year, of which SEK53.0m was derived from sales of OLYSIO and SEK184.5m from sales of other pharmaceuticals.
Last year the Food and Drug Administration approved Sovaldi, made by Gilead Sciences Inc., and Johnson & Johnson's Olysio. Both work to halt the replication of the virus over 12 weeks.
Treatment options for hepatitis C are expanding, with the FDA approving three protease inhibitors in recent years--boceprevir (Victrelis), telaprevir (Incivek), and simeprevir (Olysio)--for treatment of patients with genotype 1 infection.
