Panax Ginseng and Maraviroc

Here is the interaction we found between these two, with the evidence behind it.

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Maraviroc

Maraviroc falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Panax Ginseng interacts with.

Theoretically, Panax ginseng might increase or decrease levels of drugs metabolized by CYP3A4.
Panax ginseng may affect the clearance of drugs metabolized by CYP3A4. One such drug is imatinib. Inhibition of CYP3A4 was believed to be responsible for a case of imatinib-induced hepatotoxicity. In contrast, Panax ginseng has been shown to increase the clearance of midazolam, another drug metabolized by CYP3A4. Clinical research shows that Panax ginseng can reduce midazolam area under the curve by 44%, maximum plasma concentration by 26%, and time to reach maximum plasma concentration by 29%. Midazolam metabolism was also increased in animals given Panax ginseng. Until more is known, use Panax ginseng cautiously in combination with CYP3A4 substrates.
Severity Moderate Likelihood Possible Evidence B

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the situation with Selzentry (maraviroc) and Panax ginseng. Maraviroc is cleared from your body mainly by a liver enzyme called CYP3A4, and ginseng can nudge that enzyme in either direction. In studies it has actually sped up the breakdown of some CYP3A4 drugs (like midazolam), but in other cases it seemed to slow things down. So the direction isn't predictable.

Why this matters: maraviroc isn't a prodrug, so if ginseng speeds up its clearance, blood levels could drop and the medicine may work less well at keeping HIV in check. If levels rise instead, you might notice more side effects like dizziness or stomach upset. This is mostly theoretical, but because keeping HIV suppressed is so important, please run it by your pharmacist or HIV provider before adding ginseng.

What These Ratings Mean

Every interaction above is graded three ways — here’s the key to each label.

Severity how clinically significant the interaction is
Major

Clinically significant. Avoid the combination, or use only under close professional supervision.

Moderate

Usually worth avoiding or managing — may need monitoring, a dose change, or timing apart.

Minor

Generally not serious. Be aware of it and mention it to your pharmacist.

From our pharmacist’s overview on the Maraviroc page

“Someone taking maraviroc (Selzentry) for HIV needs a steady blood level to keep the virus suppressed, and that level is exactly what most of the 168 supplements on this page can disturb, so this list calls for genuine care. About 121 entries share maraviroc's clearance route, the CYP3A4 enzyme, which means grapefruit can push levels up…”

About Maraviroc

What Is Maraviroc Used For?

Brand names: Celsentri, Selzentry

Maraviroc treats a specific type of HIV-1 infection called CCR5-tropic HIV-1. It is always used alongside other antiretroviral (anti-HIV) medicines — never alone. A special test called a tropism assay must be done before starting treatment to confirm you have the right type of HIV.

Selzentry (the brand-name oral solution and tablet) is approved for adults and pediatric patients weighing at least 2 kg. Generic maraviroc tablets are approved for adults and pediatric patients aged 2 years and older weighing at least 10 kg. Neither form is recommended for patients whose HIV is classified as dual/mixed-tropic or CXCR4-tropic.
