Interactions


Diphenhydramine (also known as DPH, Dimedrol, Benadryl, and many others) is a deliriant substance of the ethanolamine grade. Information technology is a first-generation H1 antihistamine that is widely used as a generic, over-the-counter medication to treat allergies. When exceeding approved doses, diphenhydramine produces powerful deliriant effects.

Diphenhydramine was showtime synthesized in 1943. In 1946, it became the first prescription antihistamine approved by the U.S. Food and Drug Assistants. Information technology was approved for over-the-counter use in the 1980s.[1] Today, it is typically used to treat allergies, merely it may besides be used for a number of conditions including itchiness, insomnia, movement sickness, nausea and the symptoms of Parkinson's illness.[2]

Subjective furnishings include sedation, anxiety, tactile hallucinations, memory suppression, thought disorganization, dysphoria, and external hallucinations. Lower doses tend to produce a stoning, body-high effect while higher doses produce a state of delirium in which the user sees and hears fully-formed, extremely convincing hallucinations. Doses betwixt these two extremes are uncomfortable and dysphoric.

Notably, it is oft reported to produce meaning nausea and actual discomfort ("body load"). About users who try diphenhydramine typically do not report positive effects and do not wish to repeat the feel.

It is considered to have low abuse potential owing to its dysphoric furnishings. The toxicity of recreational use is not well-studied. Anecdotal reports suggest that chronic use (i.e. high dose, repeated administration) may cause persisting hallucinations and impairments in cognition & memory. High doses have also been linked to seizures and cardiotoxicity.[3]

It is highly advised to use harm reduction practices if using this substance.

History and civilization

Diphenhydramine was discovered in 1943 by George Rieveschl, a former professor at the University of Cincinnati.[4] [5] In 1946, it became the first prescription antihistamine approved by the United States Food and Drug Administration (FDA).[6]

In the 1960s diphenhydramine was plant to inhibit reuptake of the neurotransmitter serotonin.[7] This discovery led to a search for feasible antidepressants with similar structures and fewer side effects, culminating in the invention of fluoxetine (Prozac), a selective serotonin reuptake inhibitor (SSRI).[7] [8]

Chemistry

Diphenhydramine, or 2-(diphenylmethoxy)-N,N-dimethylethanamine, is an organic chemical compound belonging to the ethanolamine grade. The chemical construction of diphenhydramine consists of an ethylamine concatenation with two methyl groups bonded to the terminal nitrogen group RN. Additionally, this ethylamine chain is substituted at Rtwo with a diphenylmethoxy group, forming an ether. The diphenylmethoxy group consists of two aromatic phenyl rings bonded the carbon member of a methoxy group CH3O-.

DPH is produced as a hydrochloride salt.

Pharmacology

Diphenhydramine is an inverse agonist of the peripheral histamine H1 receptor and a primal histamine H1 receptor.[ citation needed ] The peripheral inverse agonism induces the allergy reducing furnishings.[ commendation needed ] Like many first-generation antihistamines, information technology is also a competitive antagonist at mACH receptors.[ citation needed ]

Diphenhydramine is an acetylcholine receptor antagonist. Although the precise machinery is not understood, the inhibition of the action of acetylcholine is idea to exist primarily responsible for the delirium, sedation and intensely realistic hallucinations alongside the extremely uncomfortable and dysphoric concrete side furnishings.

Diphenhydramine has been shown to cake sodium channels and inhibit the reuptake of serotonin.[9] [10] It also blocks voltage-gated potassium channels (VGKCs), meaning it has the potential to crusade or atomic number 82 to torsades de points, a potentially dangerous cardiac condition that tin lead to sudden cardiac death. [eleven]

Subjective effects

According to user reports, diphenhydramine displays a non-linear dose-response, pregnant the effects don't correspond directly with the dose. Doses under 300 mg are reported to produce restlessness, muscle relaxation, and a body high while doses above 500 mg begin to produce a country of delirium in which the user sees and hears fully-formed, extremely convincing hallucinations. Doses in between these two extremes are said to be uncomfortable and dysphoric. Nausea and actual discomfort ("trunk load") is reported virtually universally.

Disclaimer: The effects listed below cite the Subjective Effect Index (SEI), an open research literature based on anecdotal user reports and the personal analyses of PsychonautWiki contributors. As a outcome, they should be viewed with a healthy degree of skepticism.

Information technology is also worth noting that these furnishings will not necessarily occur in a predictable or reliable manner, although higher doses are more liable to induce the full spectrum of furnishings. Likewise, agin effects become increasingly likely with higher doses and may include addiction, astringent injury, or decease ☠.

Forms

Diphenhydramine is available in several different forms over the counter and online.

  • Pills are bachelor over the counter and online. Well-known brands include Benadryl, Benylin, Dramamine, Nytol, Sominex and ZzzQuil. Rarely, some of these products may contain other medicines, including dextromethorphan, guaifenesin, and acetaminophen. Care should exist taken when using these products to ensure that at that place is not an overdose on other medicines in these DPH-containing products.
  • Liquid is available over the counter and online. Diphenhydramine in liquid form tin can be taken orally or injected. Well-known brands include Benadryl and ZzzQuil. Rarely, some of these products may incorporate other medicines, including dextromethorphan, guaifenesin, and acetaminophen. Care should be taken when using these products to ensure that there is non an overdose on other medicines in DPH-containing products.
  • Powder is bachelor online. Diphenhydramine in powdered form can be taken orally as well as via injection. Any other routes of administration other than oral are non recommended because diphenhydramine burns and dehydrates skin tissue, which leads to extremely painful burns and bleeding.

Dimenhydrinate

Dimenhydrinate (DMH) is a combination drug of Diphenhydramine and viii-Chlorotheophylline[18], marketed equally Draminate, Dramamine, and Gravol among others, it is used to treat nausea. It is virtually commonly available as tablets, although it is too available in liquid form and as a suppository. In practice, dimenhydrinate is half as potent equally pure diphenhydramine, by weight, dimenhydrinate is between 53% to 55.5% diphenhydramine.[xix] The improver of the caffeine-like stimulant 8-Chlorotheophylline is reported to increase the dangerous cardiovascular effects diphenhydramine already has alone. This stimulant upshot is also reported to make the trip more than restless and dysphoric, with the added negative of beingness likewise wakeful to sleep the trip away.

Toxicity and harm potential

The toxicity and long-term health furnishings of recreational diphenhydramine employ have not been studied extensively.

User should note that diphenhydramine can be extremely unpredictable and the mechanism past which it produces hallucinations has the potential to outcome in serious injury, hospitalization or death. Additionally, diphenhydramine puts users in a state where they have fiddling command over their actions. Diphenhydramine can provoke bizarre and nonsensical behavior which may put the user at risk.

Cumulative diphenhydramine utilise has been tentatively linked to an increased risk of developing dementia.[20]

Overdose

The overdose threshold for diphenhydramine is usually held to be around k milligrams; nonetheless, sensitive individuals can overdose with less. The main effects of an overdose are similar to those of heavy doses. Effects include delirium, psychosis, anxiety, confusion also every bit an increased middle rate,[ commendation needed ] increased blood pressure level[ citation needed ], dryness, urinary memory, dizziness and dilated pupils. Some of the more serious side furnishings at very high doses include the adventure of seizures,[ citation needed ] and dangerous cardiovascular effects such as arrhythmia (aberrant heartbeat).[ citation needed ]

The user may completely not be able to distinguish reality from hallucinations. At that place is also a significant adventure of responding to a delusional environment and perhaps injuring themselves or others and also too much concrete activity which can farther strain the heart or cause rhabdomyolysis.[21] Individuals undergoing delusions should, if possible, not be agitated. The first lines of treatment for overdose should be benzodiazepines, although medical attending should e'er be sought.

Diphenhydramine tin can get fatal at amounts close to or exceeding 2 grams.[ citation needed ] This tin can consequence in death when combined with about stimulants, depressants and MAOIs.

Psychosis

User reports suggest that diphenhydramine causes psychosis and delirium at a significantly college rate than other hallucinogens (i.e. psychedelics and dissociatives).[ commendation needed ] There are a big number of experience reports online which describe states of psychotic delirium, amnesia, and other serious consequences after abusing the substance. In many cases, it has resulted in hospitalization and decease.[ citation needed ]

The recreational use of diphenhydramine is more often than not non advised. If deciding to employ this substance, 1 should use extreme caution and harm reduction practices, such as having a sober trip sitter.

Dependence and corruption potential

Diphenhydramine produces dependence with chronic use. In comparing to other hallucinogens, DPH has been reported to have significantly less abuse potential than other hallucinogens. This is simply because the vast majority of people who attempt it exercise not wish to repeat the feel.

Tolerance to many of the effects of DPH develops with repeated use. This results in users having to administer increasingly big doses to attain the same effects. After that, it takes about one - ii weeks for tolerance to return to baseline (in the absence of further consumption). DPH presents cross-tolerance with all deliriants, meaning that later the consumption of DPH, all deliriants will have a reduced event.

Dangerous interactions

Warning: Many psychoactive substances that are reasonably prophylactic to use on their ain can suddenly become dangerous or even life-threatening when combined with certain other substances. The following lists some known dangerous interactions (although it is not guaranteed to include all of them).

Always behave independent research (east.g. Google, DuckDuckGo, PubMed) to ensure that a combination of two or more substances is safe to swallow. Some of the listed interactions take been sourced from TripSit.

  • Selective serotonin re-uptake inhibitors (SSRIs) - SSRIs tin can suppress the visual effects of diphenhydramine. However, this combination may drag the run a risk of serotonin syndrome due to diphenhydramine's serotonergic furnishings.[ citation needed ]
  • Stimulants - Due to diphenhydramine's excitatory cardiac result, combining it with stimulants poses a hazard of an abnormal middle rhythm, severe tachycardia, or a middle set on every bit well as other cardiovascular events.
  • Benzodiazepines - Benzodiazepines can suppress the visual effects of diphenhydramine. However, this tin can combination can produce a dangerous amount of sedation and respiratory low.[ commendation needed ]
  • Anticholinergics - Due to diphenhydramine's excitatory cardiac issue, combining it with other anticholinergics poses a risk of an abnormal heart rhythm, severe tachycardia, or a heart attack as well equally other cardiovascular events (inhibition of acetylcholine causes increased middle rate).

Legal condition

Diphenhydramine is available either over the counter or by prescription in most countries. However, some countries require the purchaser to be over 16, 18 or 21.

  • Republic of zambia: Diphenhydramine is illegal to possess and sell in Zambia; foreigners have been detained for possession.[ commendation needed ]
  • U.s.: Diphenhydramine is widely bachelor over-the-counter in the Us. It is an approved drug and is legal to purchase, possess, and ingest without a license or prescription.[22]
  • Poland: Diphenhydramine is non a controlled substance nether Polish law, but is only bachelor over the counter in medicine that contains paracetamol.<ref>[ii]
