Summary PsychonautWiki

Haloperidol (trade name Haldol) is an antipsychotic drug used to treat a variety of mental disorders, such as schizophrenia, mania, bipolar disorder, delirium, psychosis, Tourette syndrome, as well as other disorders. It was first synthesized in 1958 by Paul Janssen from meperidine. Haloperidol is on the WHO Model List of Essential Medicines, the most important medications needed in a basic health system.

Effects Erowid

Aggregated from 5 single-substance Erowid experience reports; 4 Erowid reports where another drug was taken too are left out

Each bar shows the share of analyzed reports whose text mentions that effect — a mention is not always a first-hand experience (fear of an effect or something witnessed can count). Mentions saying the effect did not happen are left out; that check reads keywords, so it can miss some. The shaded band on a bar, and the small range after its number, is the 95% interval: where the share could plausibly be with other reports of the same kind. Fewer reports, wider band. Tap or hover any number for details. The second value is the Bluelight extractor's per-effect confidence; a dash means the row is Erowid-derived, which has no confidence measurement.

Too few reports for bars: these effects come from 5 single-substance Erowid reports, and a bar is drawn only from 20 reports or more. With fewer, a percentage cannot tell a common effect from a rare one. Counts are shown instead. Why 20?

Positive Effects 2

Adverse Effects 1

3 of 5 –

Also reported in combinations. In the 4 Haloperidol reports where another drug was taken too, 4 mention hospital, emergency services or an overdose, 0 a seizure and 1 psychosis (too few reports for percentages). In the 5 single-substance reports: 0, 1 and 1. These are not in the figures above: they cannot be put down to Haloperidol alone, and a mention is not always something that happened to the writer.

I Was Willing to Try Anything positive exp #105148

I am using this for bipolar disorder. My normal medication Trileptal was no longer working. I just wanted to kill myself everyday. I was extremely suicidal. I was very angry at inanimate objects. I tried several other mood stabilizers before being put into a new classification of medication.

Not Very Tranquilizing neutral exp #15417

This experience was undertaken because I have fairly bad insomnia from time to time, and was out of Kava-Kava capsules, which normally put me out fairly fast and allow nice, normal sleep.

Not for Recreational Use in Any Way cautionary exp #116293

Haloperidol (DO NOT TAKE) Haldol Do not take this at all!! This an anti psychotic medication and is not for recreational use in any way. The warning say it may cause drowsiness or muscle relaxation, but if either are true they are short-lived and negligible, unlike the powerful "Parkinson's-like symptoms" I am currentl...
