Drug & supplement interaction

Forget-me-not + Cefprozil

Cefprozil brand name: Cefzil.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Forget-me-not and Cefprozil 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.

Forget-me-not and Cefprozil

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 Cefprozil and Forget-me-not 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Forget-me-not at all — not against Cefprozil, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

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.

What to actually watch for

No Interaction Found — But Data Suggests Forget-me-not and Cefprozil 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 / Vomiting Additional detail

    Forget-me-not

    “Orally, exposure to hepatotoxic pyrrolizidine alkaloids (PA) can cause veno-occlusive disease, lung toxicity, and cancer. Symptoms of acute veno-occlusive disease include colicky pains in epigastrium, vomiting and diarrhea, and ascites formation within several days. Enlargement and induration of the liver occurs within a few weeks.”

    Listed in the ADVERSE REACTIONS section of the FDA label for Cefprozil. Read the label on DailyMed ›

Effects for Cefprozil come from the ADVERSE REACTIONS section of its FDA label; effects for Forget-me-not come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 780 voluntary FDA FAERS reports for Cefprozil 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.

Everything else you take

See Every Supplement That Interacts With Cefprozil

This page covers Forget-me-not only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Cefprozil page lists 60 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Asarabacca (major), Siberian Cocklebur (major), African Wild Potato (moderate) and Aristolochia (moderate).

By severity: 3 major · 46 moderate · 11 minor.

From our pharmacist’s overview on the Cefprozil page

“Cefprozil (Cefzil) is a cephalosporin antibiotic, usually a short course for ear, sinus, throat, or skin infections, and three of the 60 supplements on this list warrant real caution even for a week of pills. Activated charcoal can bind the drug and pull it out of your system before it works.”

About Forget-me-not

What is Forget-me-not?

  • Respiratory complaints (cough, bronchitis)
  • Nosebleeds and minor bleeding (traditional)
  • Eye complaints (folk use)
  • Skin and wound care (topical, traditional)
  • General tonic in folk medicine

Forget-me-not (Myosotis) is a small flowering plant used in folk medicine, mostly for coughs and minor ailments, but there is very little scientific research to support any health benefit. Because it belongs to a plant family that can contain potentially liver-harming compounds, and because safety data are lacking, it is best used cautiously, if at all, and avoided in pregnancy and breastfeeding.

Myosotis scorpioides · Boraginaceae · Aerial parts (flowers, leaves, and stems) · Tea, tincture, dried herb, occasionally topical preparations

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

Forget-me-not: dosing

There is no established or standardized dose for forget-me-not. It has not been studied enough to know a safe and effective amount.If you choose to use a product that contains it, follow the directions on the label and do not exceed them.

About Cefprozil

What Is Cefprozil Used For?

Brand name: Cefzil

Cefprozil tablets and oral suspension are both used to treat mild to moderate bacterial infections in adults and children. Approved uses include pharyngitis/tonsillitis (strep throat), acute sinusitis, otitis media (ear infections), acute bacterial exacerbation of chronic bronchitis, and uncomplicated skin and skin-structure infections.

Cefprozil tablets are also approved for secondary bacterial infection of acute bronchitis. Because antibiotic resistance is a real concern, cefprozil should only be used when the infection is proven or strongly suspected to be caused by bacteria that respond to it.

Most-Reported Side Effects for Cefprozil

From FAERS, the FDA’s public side-effect reporting system (780 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Chronic kidney disease 89 reports
Drug hypersensitivity 73 reports
Cough 64 reports
Acute kidney injury 59 reports
Dyspnea 59 reports

Taking Forget-me-not and Cefprozil Together: Common Questions

Is it safe to take Forget-me-not with Cefprozil?
We do not list a known interaction between Forget-me-not and Cefprozil. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Forget-me-not and Cefprozil have any of the same side effects?
Yes — our sources link each of them separately to 2 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Does Cefprozil interact with any supplements?
Yes. Cefprozil has documented interactions with 60 supplements in our database — Forget-me-not is not one of them. The Cefprozil interaction page linked on this page lists every one, ranked by severity.
