Question

Answer 1

you get very, very sleepy

Answer 2

GENERIC NAME: diphenhydramine
BRAND NAME: Benadryl
DRUG CLASS AND MECHANISM: Diphenhydramine is an antihistamine with anticholinergic (drying) and sedative properties that is used to treat allergic reactions. Histamine is released by the body during several types of allergic reactions and--to a lesser extent--during some viral infections, such as the common cold. When histamine binds to its receptors on cells, it causes changes within the cells that lead to sneezing, itching, and increased mucus production. Antihistamines compete with histamine for cell receptors; however, when they bind to the receptors they do not stimulate the cells. In addition, they prevent histamine from binding and stimulating the cells. Diphenhydramine was originally approved by the FDA in 1946.


SIDE EFFECTS: Diphenhydramine can commonly cause sedation, tiredness, sleepiness, dizziness, disturbed coordination, drying and thickening of oral and other respiratory secretions, and stomach distress. Diphenhydramine may also cause low blood pressure, palpitations, increased heart rate, confusion, nervousness, irritability, blurred vision, double vision, tremor, loss or appetite, or nausea. Diphenhydramine should be used with caution (if at all) in persons with narrow-angle glaucoma, prostatic hypertrophy (enlarged prostate gland), hyperthyroidism, cardiovascular disease, hypertension, and asthma.

Answer 3

At the most I, personally, would take is 50mg, and RARELY 75mg, but I wouldn't recommend it. It is an "anti-histamine", and they put it in allergy medicines... but it's the same exact ingredient (Diphenhydramine) as in most of the "PM" over the counter medications to make you drowsy (they don't advertise this, so a lot of people don't know).

Symptoms of a Benadryl overdose include extreme sleepiness, confusion, weakness, ringing in the ears, blurred vision, large pupils, dry mouth, flushing, fever, shaking, insomnia, hallucinations, and possibly seizures.

Answer 4

I have not personally, but have read about some who have and died. It repressed their breathing while they slept and so they never woke up.
What's awful is that parents acutally use this stuff to give to their kids as a sleep aid. That's dangerous stuff right there!!

Answer 5

It will make you EXTREMELY anxious/agitated. You won't be able to sleep. You'll be angry and irritated.
