The bottom line No known interaction

We found no known interaction between 19-nor-dhea and Cefotaxime 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.

19-nor-dhea and Cefotaxime

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 Cefotaxime and 19-nor-dhea 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.

How we checked

Why No Interaction Is Listed for Cefotaxime

Interactions in our licensed database are recorded against drug classes, not just single drug names. Cefotaxime is filed under 7 classifications — including organic anion transporter 3 (oat3) substrates, organic anion transporter 1 (oat1) substrates, antibiotic drugs. 19-nor-dhea has documented interactions with 1 drug class — the most serious being testosterone (moderate) — and none of Cefotaxime’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What Cefotaxime’s Own FDA Label Lists

This is not an interaction — none of it involves 19-nor-dhea. These are the most notable effects listed in the ADVERSE REACTIONS section of Cefotaxime’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 10 of them are worth acting on rather than waiting out — marked below.

  • Blood clots Worth acting on
  • Yellowing of the skin or eyes Worth acting on
  • Wheezing Worth acting on
  • A severe skin reaction Worth acting on
  • Seizures Worth acting on
  • A low platelet count Worth acting on
  • Kidney problems Worth acting on
  • Anemia Worth acting on
  • A severe allergic reaction Worth acting on
  • Hives Worth acting on

From the ADVERSE REACTIONS section of the FDA label for Cefotaxime. Read the label on DailyMed › 19-nor-dhea’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no 19-nor-dhea side to compare — that is a limit of the record, not a statement that 19-nor-dhea has no side effects.

Everything else you take

See Every Supplement That Interacts With Cefotaxime

This page covers 19-nor-dhea only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Cefotaxime page lists 45 supplements it has a documented interaction with, worst first, each one explained.

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

By severity: 2 major · 39 moderate · 4 minor.

From our pharmacist’s overview on the Cefotaxime page

“The two entries worth understanding first on this cefotaxime (Claforan) list are Siberian cocklebur and asarabacca. Both can damage the kidneys on their own, and stacking that on an injectable antibiotic often given to people who are already quite sick is a risk I would not take lightly.”

About 19-nor-dhea

What is 19-nor-dhea?

  • Muscle building and bodybuilding
  • Increasing strength
  • Athletic performance
  • Supporting hormone levels
  • Body recomposition

19-nor-DHEA is a synthetic 'prohormone' marketed to bodybuilders as a precursor to nandrolone-like compounds, not a natural plant supplement. There is very little reliable human research on its safety or effectiveness, and products like it carry real risks to the liver, hormones, and heart. We do not recommend using it without close medical supervision, and it may be banned in sports and restricted by law in some places.

Not applicable (a synthetic or semi-synthetic hormone derivative, not a plant part) · Capsules, tablets, sublingual tablets, sometimes combined in 'prohormone' supplement blends

An interaction check asks whether these two react with each other — it does not ask whether 19-nor-dhea is a good idea for someone in your situation. Here is what our 19-nor-dhea record says about it on its own.

19-nor-dhea: dosing

There is no established or medically recommended dose for 19-nor-DHEA. It has not been studied well enough to define a safe and effective amount.Products vary widely, and labels may not be accurate. Because of this, we cannot suggest a specific milligram amount.

About Cefotaxime Injection

What Is Cefotaxime Injection Used For?

Brand name: Claforan

Cefotaxime Injection is used to treat serious bacterial infections in many parts of the body — including the lungs, urinary tract, skin, bones and joints, abdomen, reproductive organs, and central nervous system (such as meningitis). It also treats bloodstream infections (septicemia) and certain sexually transmitted infections, including gonorrhea.

It is also given before certain surgeries — such as abdominal or vaginal hysterectomy, gastrointestinal surgery, and cesarean section — to reduce the risk of postoperative infection. Because cefotaxime has no activity against Chlamydia trachomatis, an additional antibiotic must be added when that organism is a suspected cause of pelvic inflammatory disease.
