Bromperidol (Impromen, Bromidol): Why This Butyrophenone Is Not in U.S. Pharmacies and What Telehealth Can Still Do

Last updated: August 26, 2026

Bromperidol is a first-generation butyrophenone antipsychotic used outside the United States for schizophrenia and other psychotic manifestations. Brand names include Impromen, Bromidol, Bromodol, Erodium, and Tesoprel. It is not a U.S. retail pharmacy product. If you are searching for bromperidol or Impromen because a relative used it in Europe, or because a paper cited the decanoate depot, you still can get a licensed evaluation for symptoms that need care here.

TL;DR

• Bromperidol is a typical butyrophenone discovered at Janssen in 1966. DrugBank lists it as DB12401.
• Identifiers: CAS 10457-90-6, PubChem CID 2448, UNII LYH6F7I22E, ATC N05AD06, formula C21H23BrFNO2, molar mass about 420.32 g/mol. Other names include R-11333 and C-C 2489.
• A long-acting ester, bromperidol decanoate (Impromen Decanoas), is an oil depot used in some European countries. Cochrane reviews it as CD001719.
• U.S. clinics use other antipsychotics. Coverage for those medicines may vary by plan. Verify benefits before you book.
• Klarity’s network includes 2,000+ licensed providers. Telehealth can support evaluation, follow-up, and many non-emergency mental health visits. If you are in crisis, call or text 988.

What is bromperidol?

DrugBank describes bromperidol as a first-generation butyrophenone antipsychotic used for schizophrenia and other psychotic manifestations. The public card also notes trial work that included dementia, depression, anxiety disorders, and psychosomatic disorders. That trial language is not a U.S. label and is not a reason to import the drug.

Published chemical references give the IUPAC name 4-[4-(4-bromophenyl)-4-hydroxypiperidin-1-yl]-1-(4-fluorophenyl)butan-1-one. The structure is a close analog of haloperidol, with bromine on the phenyl ring instead of chlorine. Janssen assigned the research code R-11333. ATC N05AD06 places it with other butyrophenone antipsychotics.

Trade names that appear in international directories include Impromen, Bromidol, Bromodol, Erodium, Tesoprel, Agostine, Azurene, and Consilinon. Impromen is the name many European patients recognize. Impromen Decanoas is the depot ester, not a second molecule with a different receptor profile.

Why you will not find Impromen at a U.S. pharmacy

Bromperidol does not appear as an FDA-approved brand or generic on U.S. retail lists. A U.S. clinician cannot write a standard retail prescription for Impromen the way they write for Haldol, Abilify, or Invega. Personal importation of unlabeled antipsychotics is unsafe and often illegal. Do not buy bromperidol from overseas websites.

If you transferred care from Belgium, Germany, Italy, or the Netherlands, bring the original pack, dose, and depot interval to a licensed U.S. clinician. They can map the regimen onto a medicine that is actually stocked here. That mapping is clinical work, not a one-to-one milligram swap.

How the oral drug and the decanoate depot differ

Oral bromperidol is a daily tablet in markets that still stock it. Bromperidol decanoate is an intramuscular ester in sesame oil. Wikipedia’s long-acting injectable table, compiled from published kinetic papers, lists Impromen Decanoas at 40-300 mg every 4 weeks, Tmax about 3-9 days, and a multiple-dose half-life around 21-25 days. Those figures describe foreign products. They are not U.S. dosing instructions.

The Cochrane review of depot bromperidol decanoate for schizophrenia (CD001719) states that the depot is used as a long-acting antipsychotic in at least Belgium, Germany, Italy, and the Netherlands. The evidence base is limited. Cochrane’s authors treat the comparison with placebo and with other depots as low-certainty. A U.S. reader should treat that as history of a regional product, not as a reason to seek the injection here.

U.S. long-acting options that licensed psychiatrists actually use include haloperidol decanoate, fluphenazine decanoate, and several atypical depots such as aripiprazole and paliperidone palmitate. Choice depends on diagnosis, prior response, metabolic risk, and whether a clinic can give the injection.

How bromperidol compares with other first-generation antipsychotics

Bromperidol sits in the same chemical family as haloperidol (Haldol), benperidol (Anquil), and pipamperone (Dipiperon). High-potency butyrophenones tend to cause more extrapyramidal symptoms and less weight gain than some low-potency phenothiazines. That class pattern does not tell you how you will feel on a specific tablet.

LiverTox groups many first-generation antipsychotics as a class with infrequent, usually mild liver enzyme changes. Bromperidol does not have a dedicated U.S. LiverTox chapter the way some marketed drugs do. Report jaundice, dark urine, or severe abdominal pain as an emergency, not as a telehealth follow-up.

What telehealth can still do if you searched for bromperidol

A video visit cannot ship Impromen. It can still:

• Clarify whether your symptoms fit anxiety, depression, insomnia, OCD, or another condition that telehealth often manages.
• Review medicines you already take and flag interactions a U.S. pharmacist will actually see.
• Discuss FDA-available antipsychotics or other classes when a licensed clinician judges they fit.
• Coordinate in-person care when psychosis, catatonia, or suicidality needs a higher level of service.

HHS notes that recent legislation extended many Medicare telehealth flexibilities through December 31, 2027 (telehealth policy updates, February 5, 2026). Commercial and Medicaid rules still differ by plan and state. Coverage may vary. Verify benefits before you book.

People also ask

Is bromperidol the same as Impromen?

Impromen is a brand name for bromperidol. Impromen Decanoas is the decanoate depot, not a different receptor drug.

Is bromperidol available in the United States?

No as a standard FDA-marketed retail product. U.S. clinicians use other antipsychotics that pharmacies actually stock.

Is bromperidol a controlled substance?

Typical antipsychotics are generally not scheduled the way stimulants are. Import rules and prescription status still apply. Do not order it online from overseas sellers.

Can telehealth prescribe an antipsychotic?

A licensed U.S. clinician may prescribe an FDA-available antipsychotic after an evaluation, when the medicine fits the diagnosis and state rules. They cannot create a U.S. supply of Impromen.

What should I do in a psychiatric emergency?

Call 911 or go to an emergency department. For 24/7 emotional support in the United States, call or text 988.

When to get in-person care instead

New or worsening psychosis, inability to care for yourself, neuroleptic malignant syndrome warning signs (high fever, rigidity, confusion), severe dystonia, or suicidal planning need urgent in-person care. Telehealth is the wrong channel for those presentations.

Insurance and next steps

Plan design, prior authorization, and formulary tier may change what you pay for an FDA-available antipsychotic or a therapy visit. Klarity does not promise that any plan will cover a specific medicine. Check your card, call the number on the back, and confirm network status.

Klarity connects people with 2,000+ licensed providers for many common mental health and primary-care needs. If bromperidol was only the search term and the real problem is anxiety, sleep, or mood, start with a condition page and an honest history.
