NS5B polymerase inhibitor (chronic hepatitis C)Reviewed May 22, 2026

Sofosbuvir (Sovaldi, Harvoni, Epclusa) and Ketamine Therapy | Tovani Health

Sovaldi (Sofosbuvir) (also: Harvoni (sofosbuvir + ledipasvir), Epclusa (sofosbuvir + velpatasvir))NS5B polymerase inhibitor (chronic hepatitis C)

Verdict at Tovani Health

Fully compatible; modern HCV therapy is cure-focused short-course with clean interaction profile.

Sofosbuvir-based regimens and ketamine have no clinically significant interaction. The modern direct-acting antiviral regimens (Harvoni, Epclusa, Mavyret) are short cure courses — typically 8-12 weeks — with clean profiles compared to the older interferon-based therapies they replaced. No meaningful CYP3A4 modulation at therapeutic doses.

If you take Sovaldi regularly and are considering at-home ketamine therapy, the combination is generally safe at therapeutic doses. This page covers the brief pharmacologic context and what we do at intake.

How Sovaldi interacts with ketamine

Sofosbuvir is a uridine nucleotide analog that inhibits HCV NS5B polymerase. Renally cleared after intracellular phosphorylation. No CYP interaction with ketamine.

What we do at intake

Continue your HCV regimen. Disclose start and expected end dates.

Bottom line

Sofosbuvir-based regimens and ketamine have no clinically significant interaction. The modern direct-acting antiviral regimens (Harvoni, Epclusa, Mavyret) are short cure courses — typically 8-12 weeks — with clean profiles compared to the older interferon-based therapies they replaced.
