Diphenhydramine (pron.: /ˌdaɪfɛnˈhaɪdrəmiːn/; abbreviated DPH, sometimes DHM) is a first-generation antihistamine possessing anticholinergic, antitussive, antiemetic, sedative and properties which is mainly used to treat allergies. It is also used in the management of drug induced Parkinsonian extrapyramidal. The drug has a strong hypnotic effect and is FDA approved as as a non-prescription sleep aid; especially in the form of diphenhydramine citrate. It is produced and marketed under the trade name Benadryl by McNeil-PPC (a division of Johnson & Johnson) in the U.S., Canada and South Africa (other trade names in other countries: Dimedrol, Daedalon). It is also available as a generic or store brand medication. It is also found in the name-brand products Nytol, Unisom, Tylenol PM, Excedrin PM, Midol PM, Zzzquil and Advil PM, though some Unisom products contain doxylamine instead. It is available as an over-the-counter (OTC) or prescribed HCl injectable. In addition, injectable diphenhydramine can be used for life-threatening reactions (anaphylaxis) to allergens such as bee stings, peanuts, or latex, as an adjunct to epinephrine. It is a member of the ethanolamine class of antihistaminergic agents.
Diphenhydramine was invented in 1943 by Dr. George Rieveschl, a former professor at the University of Cincinnati.[5] In 1946, it became the first prescription antihistamine approved by the U.S. Food and Drug Administration (FDA).[6]

Uses
Medicinal
Diphenhydramine is a first generation antihistamine used to treat a number of conditions including allergic symptoms and itchiness, the common cold, insomnia, motion sickness, and extrapyramidal symptoms.[7][8]
Diphenhydramine is significantly more potent in treatment of allergies than newer generation of antihistamines.[9] Consequently, it is frequently used when an allergic reaction requires fast, effective reversal of the often dangerous effects of a massive histamine release.
It is a potent antagonist to acetylcholine affecting muscarinic receptors and as a result is used to treat parkinson's disease like extrapyramidal symptoms caused by typical antipsychotics. The muscarinic receptor antagonism leads to correction of dopamine, the neurotransmitter responsible for control of motor function in the brain, similar to other antimuscarinic agents such as atropine.
Diphenhydramine has sedative properties and is widely used in nonprescription sleep aids for insomnia. The maximum recommended dose of 50 mg (as the hydrochloride salt) being mandated by the U.S. FDA. The drug is an ingredient in several products sold as sleep aids, either alone or in combination with other ingredients such as acetaminophen (paracetamol). An example of the latter is Tylenol PM. Examples of products having diphenhydramine as the only active ingredient include Unisom, Tylenol Simply Sleep, Nytol, ZzzQuil, and Sominex (the version sold in the US; that sold in the UK uses promethazine).
Diphenhydramine also has antiemetic properties which make it useful in treating the nausea that occurs in motion sickness. As it causes marked sedation in many individuals, newer generation antihistamines including Loratadine, Cetirizine, and Dimenhydrinate may be preferred for this purpose.
There are also topical formulations of diphenhydramine available, including creams, lotions, gels, and sprays. They are used to relieve itching, and have the advantage of causing much less systemic effect (i.e. drowsiness) than oral forms. [10] Diphenhydramine also has local anesthetic properties, and has been used for patients allergic to common local anesthetics like lidocaine.[11]
Diphenhydramine has potent anticholinergic properties, recent clinical evidence revealed this medication can be helpful in treating asthma and chronic obstructive pulmonary disease, allowing the bronchi to relax and causing airflow obstruction to subside[citation needed].
Recreational
Diphenhydramine acts as an analgesia potentiator with morphine in rats.[12] It is used recreationally as a deliriant, or as a potentiator of alcohol[citation needed], opiates[13] and other depressants. CNS effects occur within the limbic system and hippocampus, causing confusion and temporary amnesia.[citation needed]
Like its chemical relatives, diphenhydramine has mild to moderate euphoriant actions of its own.
Toxicology also manifests in the autonomic nervous system, causing urinary retention, pupil dilation, tachycardia, irregular urination, and dry skin and mucous membranes.[citation needed] Severe restlessness or akathesia can also be a side effect that is made worse by increased levels of diphenhydramine.[14] Considerable overdosage can lead to cardiac arrest, serious ventricular dysrhythmias, coma, and death.[citation needed]Such a side-effect profile is commonly thought to give ethanolamine-class antihistamines a relatively low abuse liability. The specific antidote for diphenhydramine poisoning (similar to that of Datura or Atropa belladonna poisoning) is physostigmine.[citation needed]
Diphenhydramine is among the prohibited and controlled substances in the Republic of Zambia.[15] Travelers are advised not to bring this drug into the country. Several Americans have been detained by the Zambian Drug Enforcement Commission for possession of Benadryl and other over-the-counter medications containing diphenhydramine.[16]
Adverse effects
Like many other first-generation antihistamines, diphenhydramine can cause strong sedation. As such, diphenhydramine has also been used as an anxiolytic because of this side-effect. It is also a potent anticholinergic agent, leading to the side-effects of dry mouth and throat, increased heart rate, pupil dilation, urinary retention, constipation, and, at high doses, hallucinations or delirium. Further side-effects include motor impairment (ataxia), flushed skin, blurred vision at nearpoint owing to lack of accommodation (cycloplegia), abnormal sensitivity to bright light (photophobia), difficulty concentrating, short-term memory loss, visual disturbances, irregular breathing, dizziness, irritability, itchy skin, confusion, decreased body temperature (in general, in the hands and/or feet), erectile dysfunction, excitability, and, although it can be used to treat nausea, higher doses may cause vomiting.[17] Some side-effects, such as twitching, may be delayed until the drowsiness begins to cease and the person is in more of an awakening mode. There are several levels of evidence strongly indicating diphenhydramine (similar to chlorpheniramine) can block the delayed rectifier potassium channel and consequently prolong the QT-interval, leading to cardiac arrhythmias, such as torsade de pointes.[18] Some patients have an allergic reaction to diphenhydramine in the form of hives.[19][20]
FDA Classification of Drug Safety During Pregnancy of Diphendranydramine is a Category B. [21] Diphenhydramine is also excreted in breast milk. [21] The medication is not recommended for children under the age of six years and should only be used in children under the age of six after consulting a physician. [22] Paradoxical reactions to diphenhydramine are documented, in particular, among children, and it may cause excitation instead of sedation[23]
Diphenhydramine is on the "Beers list" to avoid in the elderly.[24] As diphenhydramine is extensively metabolized by the liver, caution should be exercised when giving the drug to individuals with hepatic impairment.
Since 2002, the US FDA requires special labeling warning against using multiple products that contain diphenhydramine.[25] Diphenhydramine has been shown to build tolerance against its sedation effectiveness very quickly, with placebo-like results after a third day of common dosage.[26]
Chemistry
Diphenhydramine, N,N-dimethyl-(diphenylmethoxy)ethylamine, is synthesized by a simple reaction of benzhydrylbromide and 2-dimethylaminoethanol.[27][28][29]
Pharmacology
Diphenhydramine is an inverse agonist of the histamine H1 receptor.[30] By blocking histamine in the capillaries it can reduce the intensity of allergic symptoms. Diphenhydramine crosses the blood–brain barrier (BBB) and antagonizes the H1 receptors centrally. Its effects on central H1 receptors cause drowsiness.[31]
Like many other first-generation antihistamines, diphenhydramine is also a potent competitive antagonist of muscarinic cholinergic receptors, and, as such, at high doses can cause anticholinergic syndrome.[32] Diphenhydramine can also act as an antiparkinson agent as a result of the blocking properties to the muscarinic acetylcholine receptors in the brain.
In the 1960s, diphenhydramine was found to inhibit reuptake of the neurotransmitter serotonin.[33] This discovery led to a search for viable antidepressants with similar structures and fewer side-effects, culminating in the invention of fluoxetine (Prozac), a selective serotonin reuptake inhibitor (SSRI).[33][34] A similar search had previously led to the synthesis of the first SSRI, zimelidine, from brompheniramine, also an antihistamine.
Diphenhydramine also acts as an intracellular sodium channel blocker, which is responsible for its actions as a local anesthetic.[35]
Quantification
Diphenhydramine may be quantitated in blood, plasma, or serum to monitor therapy, confirm a diagnosis of poisoning in hospitalized patients, provide evidence in an impaired driving arrest, or assist in a medicolegal death investigation.[citation needed] Blood or plasma diphenhydramine concentrations are usually in a range of 10–150 μg/L in persons taking the drug orally for its antiemetic, antihistaminic or sedative effects, 0.7–2.7 mg/L (700–2700 μg/L) in those arrested for impaired driving, 1–5 mg/L in survivors of acute overdosage and 5–30 mg/L in victims of fatal overdosage.[citation needed] In some jurisdictions, diphenhydramine is often present in postmortem specimens collected during investigation of sudden infant deaths; the drug may play a role in these events.[36][37]
Rapid urine drug screens using immunoassays based on the principle of competitive binding may show false-positive methadone results for patients who have ingested Diphenhydramine.[38]
