Timiperone (Tolopelon): Why This Butyrophenone Is Not in U.S. Pharmacies and What Telehealth Can Still Do

Last updated: August 26, 2026

Timiperone (Japanese brand name Tolopelon; also listed as timiperona and timiperonum) is a butyrophenone neuroleptic. U.S. searchers usually land on chemical records, not a retail bottle. It is not a product you fill at a typical U.S. community pharmacy. If you need care for psychosis, anxiety, or another mental health condition, a licensed clinician can still evaluate you online and discuss medicines that U.S. pharmacies actually stock.

See conditions Klarity treats or start an online anxiety evaluation with a licensed provider. Coverage may vary by plan. Verify benefits before you book.

What is timiperone?

PubChem CID 3033151 records the molecular formula C22H24FN3OS, molecular weight about 397.5 g/mol, CAS 57648-21-2, and the IUPAC name 1-(4-fluorophenyl)-4-[4-(2-sulfanylidene-3H-benzimidazol-1-yl)piperidin-1-yl]butan-1-one. Synonyms include Tolopelon, Timiperona, and Timiperonum. The INN is TIMIPERONE. MeSH lists the older chemical name 4′-fluoro-4-(4-(2-thioxo-1-benzimidazolinyl)piperidino)butyrophenone.

PubChem’s DrugBank snippet describes a small-molecule drug whose INN stem “-perone” marks a tranquillizer / neuroleptic in the 4′-fluoro-4-piperidinobutyrophenone family. That language describes the chemical class. It does not mean a U.S. FDA-approved finished product sits on a commercial shelf.

Is Tolopelon available in the United States?

No U.S. retail product under the names timiperone or Tolopelon is something Klarity can prescribe or that a typical U.S. community pharmacy stocks. Country-specific first-generation antipsychotics still appear in methods papers and identifier databases. Historic or overseas use does not create a U.S. formulary listing.

Do not buy unlabeled “timiperone” from chemical vendors for self-administration. Those listings are for research or catalog use. They are not equivalent to a licensed human drug product.

How this family compares with medicines U.S. clinicians actually use

Butyrophenones that U.S. clinicians still discuss include haloperidol and, in some settings, related first-generation options. Second-generation antipsychotics and other mental health medicines have larger U.S. labeling and pharmacy supply. A visit is about diagnosis, safety (movement effects, metabolic effects, cardiac history, pregnancy, drug interactions), and what your state and DEA rules allow. It is not about recreating a Japanese brand tablet.

Klarity’s network includes 2,000+ licensed providers. Many visits are same-day. A clinician may recommend therapy, an FDA-approved medicine, a lab, or in-person care if telehealth is not enough. Insurance may, typically, or often help with evaluation or prescriptions. Coverage varies by plan. Confirm benefits first.

Request an online visit if anxiety, mood, or related symptoms are the reason you looked up this drug name.

What telehealth can still do in 2026

HHS states that recent legislation extended many Medicare telehealth flexibilities through December 31, 2027, with a policy update dated February 5, 2026 (telehealth.hhs.gov). Commercial plans set their own rules. A video visit can cover history, current medicines, side effects, and whether you need urgent in-person evaluation.

Telehealth does not replace emergency care. If you have thoughts of suicide, call or text 988. For a medical emergency, call 911.

Questions people also ask

Is timiperone the same as Tolopelon?

Yes. PubChem lists Tolopelon as a synonym for CID 3033151, along with timiperona and timiperonum.

What is the CAS number for timiperone?

57648-21-2, per PubChem.

Can I get a prescription for Tolopelon online in the U.S.?

A U.S. telehealth clinician will not write a valid retail prescription for a product that is not available as a licensed U.S. pharmacy item. They can evaluate symptoms and discuss available alternatives.

Why does this name show up next to other “-perone” drugs?

The INN stem “-perone” groups 4′-fluoro-4-piperidinobutyrophenone tranquillizers. Shared chemistry is not shared U.S. approval or supply.

Does insurance cover an evaluation if I only searched a foreign drug name?

Plans may cover a medically necessary mental health or primary-care visit even when the search term is an overseas brand. Coverage varies. Ask your insurer about telehealth benefits and prior authorization.
