The rising public health concern of diphenhydramine overdoses has been noted, with its prevalence in drug overdose deaths in the U.S.

While Benadryl is helpful for several ailments, it can be extremely harmful if it is misused. 

What is Benadryl?

Benadryl is a first-generation antihistamine widely used to lessen the symptoms of allergies, hay fever, and the common cold. Its generic name is diphenhydramine. This medication is available in various forms, including tablets, capsules, liquid, and even injections. Benadryl effectively improves symptoms such as sneezing, runny nose, sore throat from allergies, and watery eyes, making it a go-to remedy for many common ailments.

Uses of Benadryl

Benadryl is a multi-purpose medication that treats a broad spectrum of conditions. It is commonly used to manage allergic reactions, itching, and hives. Additionally, it provides relief from common cold symptoms like sneezing and runny nose. Beyond its use for allergies and colds, Benadryl is also effective in treating motion sickness, nausea, and vomiting. Many adults also turn to Benadryl as a mild sleep aid due to its sedative properties.

It Is Dangerous To Abuse Benadryl: Risk of Overdose

Benadryl can be abused if people use it incorrectly. Teens and young adults may misuse Benadryl to get high since it is so readily available. This is a dangerous practice, especially with the rise of the ‘Benadryl Challenge,’ a viral trend among teenagers involving the misuse of Benadryl to achieve hallucinations and intoxication by consuming excessive amounts of the medication.

Anticholinergic Toxicity and Symptoms

The symptoms can be severe and are even worse if the drug is combined with other substances. Anticholinergic symptoms such as dry mucous membranes, red, flushed skin, agitation, elevated heart rate and difficulty urinating can also occur.

It is also possible to overdose on Benadryl, causing dangerous toxicity to the body. Anticholinergic toxicity can present with various symptoms that can even be life-threatening. 

Intentional Overdose

Over the past decade, there have been alarming spikes in Benadryl-related suicide gestures  reported to the Missouri Poison Center. If you or someone you know is depressed or despondent, be sure to reach out for help. The significance of drug overdose and its impact on public health cannot be overstated.

What happens if you take too much Benadryl?

A Benadryl overdose may result in extreme drowsiness, nausea, vomiting, unsteadiness, dry mouth, increased heart rate, blurred vision, and confusion. Severe symptoms such as hallucinations, seizures, coma and death can also occur. Severe diphenhydramine overdose can lead to potential cardiac symptoms. The rising trend of drug overdose deaths due to diphenhydramine is a pressing public health concern.

Safe Medication Storage and Use

To prevent accidental ingestion and potential overdose, it is crucial to store Benadryl and other medications safely. Here are some essential tips for safe medication storage and use:

  • Keep medications out of reach of children and pets.
  • Use a secure and locked cabinet or storage container for medications.
  • Dispose of expired or unused medications properly.
  • Always read the label before taking any medication.
  • Follow the recommended dosage and never exceed the advised amount.
  • Be cautious of combination products that may contain diphenhydramine.

By following these guidelines, you can help ensure the safe use of Benadryl and reduce the risk of accidental diphenhydramine overdose.

Be Aware of Combination Products

Many over-the-counter (OTC) and prescription medications contain diphenhydramine, either alone or in combination with other drugs such as pain relievers, fever reducers, and decongestants. When using Benadryl, it is essential to read the label carefully before taking any other OTC medicine. Inform your healthcare provider about all the medications you are currently taking to avoid the risk of diphenhydramine overdose. Some commonly available diphenhydramine-containing products include:

  • Benadryl Allergy Plus Congestion
  • Benadryl Allergy Plus Sinus
  • Benadryl Allergy Plus Cold
  • Tylenol Cold and Allergy
  • Advil Cold and Sinus

By being aware of these combination products, you can prevent accidental antihistamine overdose and ensure the safe use of diphenhydramine.
