Benadryl, known generically as diphenhydramine, is a common over‑the‑counter antihistamine used to treat allergies, the common cold, and sleeplessness. It’s legal, easy to get, and—when used properly—safe. But when taken in high doses or without medical advice, it can be abused, leading to serious health risks including addiction, withdrawal, and even death. This blog dives into Benadryl abuse: what it is, why it happens, how to recognize it, and how to get help.
What Is Benadryl Abuse?
Benadryl abuse refers to taking diphenhydramine in doses higher than recommended or using it to induce psychoactive effects like sedation, hallucinations, or euphoria. Because it acts as a first-generation antihistamine and potent anticholinergic, misusing it can lead to dangerous mental and physical effects.
One alarming trend is the so‑called “Benadryl Challenge,” promoted on social media like TikTok. It urged users—often teens—to take large amounts of Benadryl to film themselves hallucinating. This has resulted in hospitalizations and at least one death. The FDA issued warnings, and medical professionals strongly advise against this craze.
Why Do People Abuse Benadryl?
Several reasons drive Benadryl abuse:
Easy access: Benadryl is non‑prescription and stocked in most pharmacies.
Desire for sedation or “trip”: At high doses, diphenhydramine can cause delirium, hallucinations, and sedation, which some find appealing.
Self‑medication: Some individuals use it in excess to manage insomnia, anxiety, or to reduce side effects of other medications.
Peer influence: Social media challenges glamorizing Benadryl abuse have contributed to experimentation, especially among youth.

Risks and Health Dangers of Benadryl Abuse
Misusing Benadryl comes with serious risks:
1. Physical Effects
Anticholinergic poisoning: Overdose can lead to dry mouth, flushed skin, increased heart rate, urinary retention, constipation, blurred vision, and hyperthermia.
Heart problems: At high doses, diphenhydramine may elongate the QT interval, raising the risk of dangerous heart rhythms like torsades de pointes.
Organ damage and death: Seizures, coma, cardiovascular collapse, and fatal outcomes can occur in overdose.
2. Mental and Cognitive Impacts
Delirium and hallucinations are not uncommon with large doses.
Cognitive decline in older adults: Long‑term diphenhydramine use is linked to confusion, memory problems, and increased risk of dementia.
3. Dependence and Withdrawal
Repeated misuse may lead to dependence, where a person needs more to achieve the desired effects. Abrupt stopping can bring withdrawal symptoms.
National case reports highlight patients using extremely high dosages (e.g., 30 x 50 mg tablets per day) who developed withdrawal syndromes similar to psychosis or tremor, requiring medically managed tapering.
Withdrawal can include anxiety, tremors, insomnia, nausea, confusion, even seizures.
Signs of Benadryl Addiction and Abuse
Key warning signs include:
Increased use or dosage beyond instructions
Intense cravings or inability to cut down
Tolerance, needing more over time
Withdrawal symptoms when not using
Neglecting responsibilities due to use
Continuing use despite harms, physical or social
What to Do If You or Someone You Know Is Misusing Benadryl
1. Seek Professional Help
If someone is experiencing signs of Benadryl dependence or withdrawal, it’s crucial to seek medical evaluation. Detox may be necessary with supervision and tapering under physician guidance.
2. Support Recovery
Recovery often involves:
Medical detox with gradual tapering
Counseling for substance misuse behaviors
Education on safe medication use
Building healthy coping strategies
Facilities and addiction centers offer structured recovery programs tailored for OTC medication misuse.
3. Prevent Future Abuse
Stay informed and avoid non‑medical use
Clinicians should educate patients about risks of off‑label or excessive use
Parents and caregivers should monitor youth, especially regarding social media influence
While Benadryl (diphenhydramine) serves a legitimate role in relieving allergies and aiding occasional sleep, its misuse is a dangerous path. Benadryl abuse can lead to hallucinations, organ damage, dependence, and even death. Withdrawal can be harsh and may require medical attention. If you or someone you know is using Benadryl in risky ways, don’t wait—seek professional help.
