Drug & supplement interaction

Ornithine Ketoglutarate (okg) + Cefoxitin

Cefoxitin brand name: Mefoxin.

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 Ornithine Ketoglutarate (okg) and Cefoxitin 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.

Ornithine Ketoglutarate (okg) and Cefoxitin

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 Cefoxitin and Ornithine Ketoglutarate (okg) 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 Ornithine Ketoglutarate (okg) at all — not against Cefoxitin, 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.

Ornithine Ketoglutarate (okg) safety at a glance

Ornithine Ketoglut... overall Use caution Generally well tolerated in short-term clinical studies, but long-term safety as a daily supplement is not well established.
Pregnancy Avoid There is not enough safety information, so it is best avoided during pregnancy.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

No Interaction Found — But Data Suggests Ornithine Ketoglutarate (okg) and Cefoxitin 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.

Reported for Ornithine Ketoglutarate (okg) but not commonly for Cefoxitin: bloating or gas.

Effects for Cefoxitin come from the ADVERSE REACTIONS section of its FDA label; effects for Ornithine Ketoglutarate (okg) come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 1,373 voluntary FDA FAERS reports for Cefoxitin 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.

From our pharmacist’s overview on the Cefoxitin page

“Cefoxitin (Mefoxin) is an injectable antibiotic, usually given in a hospital or clinic for serious infections, and its supplement list deserves genuine care rather than a quick skim.

About Ornithine Ketoglutarate (okg)

What is Ornithine Ketoglutarate (okg)?

  • Wound healing and recovery from injury
  • Muscle preservation in older or hospitalized adults
  • Sports and athletic performance
  • Recovery from burns or surgery
  • Support during malnutrition or critical illness

Ornithine ketoglutarate (OKG) is a compound made by combining the amino acids ornithine and alpha-ketoglutarate, and it has mainly been studied in hospital settings for wound healing, burns, and malnutrition. Evidence for everyday use, such as sports performance, is limited and not convincing. Talk to your pharmacist or doctor before using it, especially if you have a health condition.

About Cefoxitin Injection

What Is Cefoxitin Injection Used For?

Brand name: Mefoxin

Cefoxitin for Injection and Dextrose Injection is used to treat bacterial infections in many parts of the body, including the lungs (pneumonia), urinary tract, abdomen, female reproductive system, bloodstream (septicemia), bones and joints, and skin. It works only against bacteria — not viruses.

Cefoxitin for Injection and Dextrose Injection is also used to prevent infection in people having certain surgeries, including gastrointestinal surgery, vaginal hysterectomy, abdominal hysterectomy, or cesarean section. It does not have activity against Chlamydia trachomatis, so additional medication may be needed when that germ is suspected.

Most-Reported Side Effects for Cefoxitin

From FAERS, the FDA’s public side-effect reporting system (1,373 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Drug resistance 90 reports
Nausea 80 reports
Drug reaction with eosinophilia and systemic symptoms 79 reports
Rash 77 reports
Thrombocytopenia 62 reports
