African Wild Potato and Zopiclone

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

African Wild Potato interacts with whole categories of medication. Zopiclone falls into 2 of those categories, so it can interact with African Wild Potato in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

1 of 2

Why this applies to Zopiclone

Zopiclone falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group African Wild Potato interacts with.

In vitro evidence shows that African wild potato extract can inhibit cytochrome P450 3A4 (CYP3A4) enzyme activity by up to 86%. Theoretically, African wild potato might increase levels of drugs metabolized by CYP3A4. However, in human research, African wild potato does not seem to affect the pharmacokinetics of Efavirenz, a CYP3A4 substrate. Until more is known, use African wild potato cautiously or avoid in patients taking drugs metabolized by CYP3A4. Some drugs metabolized by CYP3A4 include lovastatin (Mevacor), ketoconazole (Nizoral), itraconazole (Sporanox), fexofenadine (Allegra), triazolam (Halcion), and numerous others.
Severity Moderate Likelihood Possible Evidence D

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 gist for your sleep aid. Your body relies partly on an enzyme called CYP3A4 to clear zopiclone out of your system. In lab dishes, African Wild Potato has been shown to slow that enzyme down quite a bit. If that same effect happened in real people, zopiclone could hang around longer than usual, meaning more grogginess, dizziness, a heavy 'next-morning hangover' feeling, and possibly trouble with balance or memory.

The honest part: this concern comes only from test-tube research, not from people, and a human study with a different CYP3A4 drug showed no real effect. So this is more theoretical than proven. Still, since both can make you drowsy, it's worth a quick chat with your pharmacist or doctor before combining them.

CYTOCHROME P450 2C8 (CYP2C8) SUBSTRATES

2 of 2

Zopiclone also falls under CYTOCHROME P450 2C8 (CYP2C8) SUBSTRATES.

In vitro research shows that African wild potato extract might inhibit cytochrome P450 2C8 (CYP2C8). However, this effect has yet to be reported in humans. Until more is known, use with caution. Theoretically, concomitant use of African wild potato with CYP2C8 substrates might increase the risk for adverse effects from these substrates. Some drugs metabolized by CYP2C8 include amiodarone (Cordarone), paclitaxel (Taxol); nonsteroidal anti-inflammatory drugs (NSAIDs) such as diclofenac (Cataflam, Voltaren) and ibuprofen (Motrin); rosiglitazone (Avandia); and others.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the short version: in a lab dish (test tube only, not yet in people), African Wild Potato seemed to slow down a liver enzyme called CYP2C8. The theory is that if that enzyme gets blocked, drugs it helps clear could build up and hit you harder. Zopiclone is an active sleep medicine, not a prodrug, so if its breakdown slowed, you'd expect more of its effects.

In practice, Zopiclone is mainly handled by other enzymes (mostly CYP3A4 and CYP2C8 plays a smaller role), so this concern is mostly theoretical. Still, if you noticed extra next-day grogginess, deeper drowsiness, dizziness, or that bitter metallic taste, that could be a sign. Since the evidence here is weak, don't stop anything, just check with your pharmacist or doctor before combining them.

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.

Likelihood how strong the evidence is that the interaction actually happens in people
  • LikelyWell-controlled human studies have demonstrated the likely existence of this interaction.
  • ProbableInteraction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • PossibleInteraction 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.
  • UnlikelyInteraction has been demonstrated in animal or in lab research but has been shown not to occur in humans.
Evidence the quality of the studies behind the rating (graded A–D)
  • AHigh-quality meta-analysis (quantitative systematic review).
  • BCase-control study.
  • CConsensus.

From our pharmacist’s overview on the Zopiclone page

“Zopiclone is a prescription sleep aid, which makes this one of the pages I read with real concern, because the most dangerous combinations add sedation of their own. Nearly 80 of these ingredients depress the nervous system, and stacked on a sleeping pill they can bring heavy drowsiness or, at worst, slowed breathing.”
