What is Diphenhydramine?
Diphenhydramine is the main ingredient in Benadryl, an antihistamine used to treat itching and pain caused by cuts, insect bites, poison ivy, and poison oak. Diphenhydramine can also treat symptoms of allergies, hay fever, and cold symptoms. This drug targets histamine H1 receptors, reducing allergy symptoms (from the term “antihistamine”). Histamine is a natural chemical in our body that defends the immune system from allergens. An allergic reaction happens when the body releases a large amount of histamines. Diphenhydramine is also used to treat motion sickness, induce sleep, and treat certain symptoms of Parkinson’s disease.
In addition to relieving allergy symptoms, it’s also known for causing raised energy and mild euphoria in its users. As a result, many people have started abusing this medication. This is according to the National Center for Biotechnology Information (NCBI) . Moreover, because it’s an over-the-counter (OTC) drug, almost anyone can get it. While some States make it illegal for someone under the age of 18 to obtain Benadryl and other over-the-counter medicines containing diphenhydramine, cases of misuse and even addiction have been reported. Diphenhydramine addiction withdrawal is a real threat. Someone who abruptly stops taking this drug after they’ve become addicted may suffer from severe withdrawal symptoms.
Diphenhydramine (DPH) is also a powerful competitive antagonist of muscarinic acetylcholine receptors and can cause sinus tachycardia, mydriasis, xerostomia, blurred vision, ileus, urinary retention, central nervous system (CNS) depression, agitation, hyperactivity, or psychosis . Given widespread and unrestricted use of this medication, it is important to recognize signs and symptoms of chronic diphenhydramine (DPH) abuse and acute withdrawal to provide timely and effective treatment while avoiding the use of unnecessary and potentially harmful medications.

The U.S. Food and Drug Administration (FDA)  is warning that taking higher than recommended doses of the common over-the-counter (OTC) allergy medicine diphenhydramine (Benadryl) can lead to serious heart problems, coma, seizures, or even death. FDA is aware of news reports of people ending up in emergency rooms or dying after participating in the “Benadryl Challenge” encouraged in videos posted on the social media application.

Diphenhydramine Addiction Symptoms
Although many people believe over-the-counter (OTC) drugs aren’t addictive, you can become addicted to this particular drug. In fact, addiction to this medication has become a growing concern.
Much of the confusion behind diphenhydramine misuse is that many people believe it’s safe because they can just go to the drugstore and get it on their own. However, addiction o this medicine has become a problem for most people who have relied on Benadryl to treat their allergy symptoms or for sleep.
Like any other prescription drug dependency, Benadryl dependency happens when someone is psychologically dependent on it. The individual cannot work or carry out their day without taking diphenhydramine. This usually begins with regular use of normal doses. In particular, those who use this medication to sleep may develop a tolerance to their usual dose and may require more of it to experience the same effects.
Over a period of time, this behavior pattern becomes Benadryl abuse, which may lead to addiction. Because so many people have Benadryl in their medicine cabinets, it’s important to know what the symptoms of diphenhydramine abuse are.
Physical Symptoms of Diphenhydramine Addiction
- Liver damage
- Increased heart rate
- Low blood pressure
- Dry mouth, which can cause dental issues
