Home > Featured for Drug Addiction > Can You Get High on Benadryl?

April 3, 2021 By Chris Foy

Can You Get High on Benadryl?

High on Benadryl?

Some over-the-counter drugs such as Benadryl can mimic the types of high feelings that marijuana and other drugs produce. The active drug in Benadryl is diphenhydramine. When taken according to directions, this drug is meant to treat symptoms of colds and allergies, and it’s sometimes used for motion sickness or insomnia. Benadryl is usually effective and safe to use, but it can be misused as well. When taken in greater quantities than recommended, this and other nonprescription drugs can have dangerous side effects and become a danger to health.

What Is Benadryl?

Benadryl is a nonprescription medication that can be used to fight the effects of allergies and colds. It’s classified as an antihistamine and can lessen symptoms such as sneezing, runny nose and itchy or watery eyes. Benadryl is also taken for its ability to alleviate hives and the redness and itchy skin caused by insect stings or allergic reactions.

How Does Benadryl Work?

Diphenhydramine, the active ingredient in Benadryl, is an antihistamine, and it attacks histamines — substances produced by the body. Histamines fight bodily invaders, such as pollen and cold viruses. The antihistamine action of Benadryl stops some of the histamines from doing their job, preventing excess inflammation. Taking too much of the drug, however, can heighten side effects and be dangerous to your health.

Is Benadryl Safe to Take?

When taken in the appropriate dose, Benadryl is safe and effective. But our bodies are designed for homeostasis, a type of equilibrium that supports a narrow range of tolerance for drugs. Histamines serve a purpose, and taking too much Benadryl can inhibit them too severely, causing side effects such as blurred vision, headache, gastrointestinal discomfort and dry mouth.

Benadryl is not supposed to be used long term, and taking it for an extended period of time can lead to problems such as anxiety, memory loss, constipation and blurred vision. It can also impair thinking and exacerbate restless leg syndrome. If long-term medication is needed, a physician can prescribe a different type of drug that’s safer to use on a regular basis.

How Much Is Too Much?

The smallest dosage that produces relief should be used and no more often than the directions on the package specify. For adults, the typical dosage for hay fever, allergies and cold symptoms is 25 to 50 mg, taken every 4 to 6 hours as needed. The maximum adult dosage of Benadryl is 300 mg per day. The four most common side effects of Benadryl, when taken as directed, are:

  • Drowsiness
  • Headache
  • Dry mouth
  • Dizziness

Several factors affect the severity of side effects, including a person’s age, weight, hydration and whether they’re taking any other medications. Ingesting more than the recommended dose may lead to dry nasal membranes, an upset stomach, constipation, agitation and a feeling of weakness. These symptoms are rare, and if you’re experiencing them, you should check with your doctor before taking any more Benadryl. People who have liver or kidney disease should also check with a physician before taking Benadryl, and it may be contraindicated for those with:

  • Heart disease
  • High blood pressure
  • Low blood pressure
  • Bronchitis
  • Emphysema
  • Thyroid disease
  • Glaucoma
  • Asthma

What Is a Benadryl High?

A Benadryl trip can mimic the high feeling caused by some recreational drugs due to feelings of extreme drowsiness. Large doses of Benadryl can also cause confusion and memory loss and lead to a Benadryl overdose. As with some opioids, frequent users can even develop a dependence on the drug. Ingesting alcohol or taking other drugs along with diphenhydramine can intensify the experience of being high, but it’s extremely dangerous.

Why Do People Abuse Benadryl?

Those in search of a Benadryl high don’t realize that it’s not a drug that can be used to create the type of feelings experienced from using alcohol, marijuana or opioids. There’s been a recent epidemic of young people taking the “Benadryl challenge” popularized on social media. Its availability as an over-the-counter drug may be a reason for this disturbing trend, along with the teenage desire to experiment.

Symptoms of a Benadryl Overdose

Those searching for a Benadryl high can end up overdosing if they take more than 500 to 1,000 mg, or 10 to 20 times the highest recommended adult dose. Certain drugs can magnify the sedative effects, and dehydration can keep the body from metabolizing the drug effectively. In extreme cases, a Benadryl overdose can lead to heart problems, hallucinations, seizures and death.

A person can accidentally overdose on Benadryl by taking another dose before the last one has worn off or by forgetting and repeating a dosage. If someone who’s taken Benadryl collapses, can’t be awakened, has a seizure or has difficulty breathing, call 911 immediately. Symptoms of a Benadryl overdose may include:

  • Anxiety
  • Confusion
  • Dizziness
  • Amnesia
  • Inability to urinate
  • Increased heart rate
  • High blood pressure
  • Abnormal heartbeat
  • Delirium
  • Psychosis
  • Seizures

Don’t Take It for the Side Effects

Some people engage in recreational drug use because they hope it will make them feel happy and excited. Benadryl doesn’t elevate the mood, provide a burst of energy or give feelings of euphoria. Instead, it can make a person feel jittery, unsettled and confused. It’s dangerous to try to get high on Benadryl because the drug affects the body in other ways that can be damaging and even fatal.

Factors such as other drugs and the time it takes to metabolize Benadryl can cause you to take a more dangerous dose than you realize. Diphenhydramine affects the body’s organs, especially the liver, and it can cause permanent damage to the kidneys, where it’s processed and eliminated from the body.

Help Is Available

If you’re dependent on Benadryl or any other drug, help is available. A drug treatment program can help you understand the root of the compulsion to abuse medications. FHE Health provides a nonjudgmental, safe place to explore your issues and learn how to make changes.
