Phenpromethamine and Dinutuximab

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 Dinutuximab and Phenpromethamine 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.

What to actually watch for

What Dinutuximab’s Own FDA Label Lists

This is not an interaction — none of it involves Phenpromethamine. These are the most notable effects listed in the ADVERSE REACTIONS section of Dinutuximab’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.

  • Low magnesium Worth acting on
  • Liver problems Worth acting on mentioned in 15.4% of FDA reports for Dinutuximab
  • Trouble passing urine Worth acting on
  • Low sodium Worth acting on
  • Low potassium Worth acting on
  • High blood sugar Worth acting on
  • Wheezing Worth acting on
  • Chest pain Worth acting on
  • A low platelet count Worth acting on
  • Kidney problems Worth acting on

Showing the 10 most notable of 33 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Dinutuximab. Read the label on DailyMed › Where a percentage is shown, it is the share of 805 voluntary FDA FAERS reports for Dinutuximab that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Phenpromethamine’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Phenpromethamine side to compare — that is a limit of the record, not a statement that Phenpromethamine has no side effects.

About Phenpromethamine

What is Phenpromethamine?

  • Nasal decongestion (historical)
  • Stimulant effects (misuse)
  • Pre-workout 'energy' (illegally added to some products)

Phenpromethamine is a synthetic stimulant drug, not a herb or legitimate dietary supplement. It has been found illegally added to some sports and weight-loss supplements, and it is not approved for use in the United States. You should avoid any product that lists it as an ingredient and talk to a pharmacist or doctor.

Not applicable; phenpromethamine is a synthetic chemical, not a plant part · Historically found as a nasal inhaler; not a legitimate dietary supplement ingredient

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

Phenpromethamine: dosing

There is no established or recommended dose of phenpromethamine for supplement use. It is not an approved supplement ingredient, and any amount found in products is unregulated and potentially unsafe.Because the amount in spiked products is unknown and uncontrolled, no dose can be considered safe. The best advice is to avoid products that contain it entirely.
