    Safety Precautions

    How Benadryl Works

    Benadryl is quickly absorbed after oral administration and it starts to work within 30 minutes with peak effects reached within one to two hours. The effects of Benadryl last from four to six hours.

  • Blood vessels in the nose constrict, reducing nasal congestion and runny nose.
  • Antihistamines bind to histamine receptors in the brain, blocking the action of histamine.
  • The brain’s trigeminal nerve is stimulated, which can help relieve itching and other symptoms associated with allergies.
  • Safety Precautions

    Benadryl may cause blurred vision and may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert and able to see clearly.

  • Do not use extra medicine to make up for a missed dose.
  • Seek emergency medical attention or call the Poison Help line at 1-800-222-12
  • Avoid drinking alcohol while taking Benadryl, as it can increase certain side effects of diphenhydramine.
  • Side Effects

    Common Benadryl side effects may include:

    • dizziness, drowsiness, loss of coordination;
    • dry mouth, nose, or throat;
    • constipation, upset stomach;
    • dry eyes, blurred vision;
    • day-time drowsiness or “hangover” feeling after night-time use.

    Interactions with Other Medications

    Ask a doctor or pharmacist before using this medicine if you are also using any other drugs, including prescription and over-the-counter medicines, vitamins, and herbal products. Some medicines can cause unwanted or dangerous effects when used together.

  • Combination of Benadryl with sleeping pills, narcotic pain medications, muscle relaxers, or anxiety medications may worsen sleepiness.
  • Benzodiazepines, such as alprazolam (Xanax), should be avoided in patients taking diphenhydramine because it can increase the risk of sedation and other serious side effects.
  • The Hat Man

    The Hat Man is a fictional figure that started appearing on certain internet sites in the early 2000s that has recently been referred to as the “Benadryl Hat Man” after reports of people hallucinating and sighting him after overconsumption or abuse of Benadryl. Most of these reports have appeared on Reddit or the image-based bulletin site 4chan.

    Paradoxical Excitation

    One of the most common side effects with Benadryl is drowsiness, but in some people it can have the opposite effect, known as paradoxical excitation. Instead of feeling sleepy, you may experience excitation, agitation or insomnia (trouble sleeping), which might make your anxiety symptoms feel worse. This may be more common in young children.

    Benadryl for Sleep

    Benadryl (generic name: diphenhydramine) is an antihistamine that causes sleepiness in most people. Some people use Benadryl to help with sleep or insomnia, but this should only be for short-term use. Do not use Benadryl to make a child sleepy.

    Contact your doctor if you or your child are having trouble with sleep.

    Using Benadryl in Dogs

    Some vets might recommend these human over-the-counter (OTC) products, but at specific doses used only in dogs, as recommended by your vet.
