From the Research

There are no significant drug interactions between VELASOF/SOVIHEP V (sofosbuvir/velpatasvir) and zolpidem, and these medications can generally be taken together without dose adjustments. VELASOF/SOVIHEP V are direct-acting antiviral medications used to treat hepatitis C, while zolpidem is a sedative-hypnotic medication used for insomnia. The metabolism pathways of these drugs differ significantly, with sofosbuvir primarily metabolized through the liver without involving the CYP450 enzyme system that could potentially interact with zolpidem. Velpatasvir is metabolized by CYP2B6, CYP2C8, and CYP3A4, while zolpidem is primarily metabolized by CYP3A4, but the overlap does not appear to cause clinically significant interactions, as supported by the most recent study 1.

Some key points to consider when taking these medications together include:

  • Informing healthcare providers about all medications being taken, including over-the-counter drugs and supplements, to ensure comprehensive medication management.
  • Monitoring for unusual side effects, such as excessive sedation or changes in hepatitis C treatment effectiveness, and contacting healthcare providers promptly if they occur.
  • Understanding that the efficacy and safety of sofosbuvir/velpatasvir have been observed in various patient populations, including those with compensated cirrhosis and prior treatment failures, as shown in studies such as 2 and 3.
  • Recognizing that while shortened duration therapy for acute and recent HCV infection has been explored, a standard 12-week course of sofosbuvir/velpatasvir remains the recommended treatment duration, as indicated by the results of study 4.

Overall, the combination of VELASOF/SOVIHEP V and zolpidem is considered safe and effective, with no significant drug interactions reported in the literature, including the most recent and highest quality studies 1, 4.
