Drug & supplement interaction

African Wild Potato + Pertuzumab

Pertuzumab brand name: Perjeta.

No Known Interaction
The bottom line No known interaction

We found no known interaction between African Wild Potato and Pertuzumab in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

African Wild Potato and Pertuzumab

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Pertuzumab and African Wild Potato in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

African Wild Potat... overall Use caution Limited human safety data and unclear effective doses mean it should be used cautiously.

What to actually watch for

No Interaction Found — But Data Suggests African Wild Potato and Pertuzumab May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do.

  • Diarrhea / Stomach upset / Constipation / Vomiting / Nausea reported in 13.3% of FDA reports for Pertuzumab Additional detail

    African Wild Potato

    Pertuzumab

    Listed in the ADVERSE REACTIONS section of the FDA label for Pertuzumab, and in voluntary FDA adverse-event reports. Read the label on DailyMed ›

Reported for African Wild Potato but not commonly for Pertuzumab: erection problems, a change in sex drive and anxiety or restlessness.

Effects for Pertuzumab come from the ADVERSE REACTIONS section of its FDA label; effects for African Wild Potato come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 30,695 voluntary FDA FAERS reports for Pertuzumab that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

About African Wild Potato

What is African Wild Potato?

  • Immune support
  • Prostate and urinary symptoms
  • Inflammation
  • General tonic/wellness
  • Skin conditions

African Wild Potato (Hypoxis hemerocallidea) is a southern African plant traditionally used as a tonic and for immune, prostate, and inflammatory complaints. Human evidence for these uses is very limited, and safety—especially during pregnancy, breastfeeding, or with serious illness—is not well established. Talk to a pharmacist or doctor before using it.

Hypoxis hemerocallidea · Hypoxidaceae · Corm (underground tuber/rootstock) · Capsules, tablets, tinctures, dried corm extracts, traditional decoctions

An interaction check asks whether these two react with each other — it does not ask whether African Wild Potato is a good idea for someone in your situation. Here is what our African Wild Potato record says about it on its own.

African Wild Potato: dosing

There is no well-established, standardized dose for African Wild Potato. Products vary widely in strength and in how they are prepared, so it is hard to compare one to another.If you choose to use it, follow the directions on the product label and do not exceed them. A pharmacist can help you review a specific product, check for quality concerns, and make sure it is appropriate for you. Choose products from reputable manufacturers, since supplement quality is not tightly regulated.

Taking African Wild Potato and Pertuzumab Together: Common Questions

Is it safe to take African Wild Potato with Pertuzumab?

Do African Wild Potato and Pertuzumab have any of the same side effects?
Yes — our sources link each of them separately to 5 of the same effects. That is not an interaction: neither changes how your body handles the other.

Yes. African Wild Potato has 1,005 documented drug interactions in our database — Pertuzumab is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
