The bottom line No known interaction

We found no known interaction between Molybdenum and Dexchlorpheniramine 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.

Molybdenum and Dexchlorpheniramine

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 Dexchlorpheniramine and Molybdenum 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 Molybdenum at all — not against Dexchlorpheniramine, 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

What Molybdenum Itself Has Been Linked To

This is not an interaction — nothing below involves Dexchlorpheniramine. It is the side-effect record for Molybdenum on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Molybdenum, this list is the first place to look. One entry is worth acting on rather than waiting out — marked below.

  • Hallucinations / Seizures / Low mood Worth acting on Additional detail

    “In one case report of a man in his late thirties, dietary supplementation with molybdenum 300-800 micrograms daily for a cumulative dose of 13.5 mg over 18 days resulted in acute psychosis with visual and auditory hallucinations, petit mal seizures, and a life-threatening grand mal attack, related to frontal cortical damage. Chelation therapy with calcium ethylene diamine tetraacetic acid (CaEDTA) was required.”

Everything above comes from the Natural Medicines adverse-effect record for Molybdenum — expand a row for the licensed statement it rests on. We haven’t matched Dexchlorpheniramine to its FDA label in our system yet, so we can’t compare its own side-effect list here — the leaflet that comes with your prescription is the authoritative list for Dexchlorpheniramine.

Lactation Likely Safe

When used orally and appropriately. Molybdenum is safe when used in amounts that do not exceed the Tolerable Upper Intake Level (UL) of 2 mg/day for breast-feeding women 19 years of age or older, or 1.7 mg/day for breast-feeding women ages 14 to 18 years.

Lactation Possibly Unsafe

This page covers Molybdenum only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Dexchlorpheniramine page lists 198 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Grapefruit (major), Henbane (major), Lithium (major) and Scopolia (major).

By severity: 6 major · 149 moderate · 43 minor.

From our pharmacist’s overview on the Dexchlorpheniramine page

“An allergy antihistamine like dexchlorpheniramine (Polaramine) sounds mild, but its interaction list warrants genuine care, and six of the 198 entries carry a major rating. The biggest cluster, 121 ingredients, can raise or lower the drug's blood levels through the liver enzyme that breaks it down.”

About Molybdenum

What is Molybdenum?

  • Correcting molybdenum deficiency
  • Supporting enzyme function
  • General nutritional supplementation
  • Sulfite sensitivity (popular claim)

Molybdenum is an essential trace mineral your body needs in tiny amounts to help certain enzymes work. Most people get enough from a normal diet, so supplements are rarely needed unless a doctor identifies a true deficiency. At normal dietary amounts it is considered safe, but high-dose supplements should be used cautiously and under professional guidance.

Tablets, capsules, multivitamin/mineral products, liquid drops

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

Molybdenum: dosing

There is no special "treatment dose" of molybdenum for most people, because deficiency is rare and the body only needs a tiny amount. Health authorities have set recommended daily intakes that are met easily through a normal diet.If you choose to use a supplement, follow the dose on the product label and do not exceed it.

About Chlorpheniramine

What Is Chlorpheniramine Used For?
