 5  allergies-Asthma, sinus & itching when first starting there was some drowsiness. I take generic benadryl for my allergies since childhood. Side effects listed here such as drowsiness and difficulty moving are symptoms I have seen as a hangover from my allergies with or without the benadryl. I have used Benadryl off and on for over 50 years now. No other medicine is as effective on my "Hay Fever, hives and asthma. It has helped make life bearable with allergies which would keep me isolated indoors all summer, and drive me outside everytime I encountered a perfume. I would originally only take it when having bad reactions but have settled in to taking it twice a day and more often if having a bad attack. There is only one symptom I have seen. I do have hypertension which needs medical treatment but doctors have never attributed it to the benadryl. However I do show much worse elevation in pressure during allergic reactions. Although doctors say benadryl has no effect on asthma: For the last 15 years or so years I have never had an bad attach which required emergency treatment unless I am enclosed with a large source of mold spores for a long time for the most I am sure the benadryl is helping me keep milder attacks away.

 2  Sinus pressure congestion Benadryl actually worked ok reliving sinus pressure. But my white blood cell and neutrophil count plummeted! WBC 4,000 neutrophil 2,500 before taking. Took for 4 months had regular blood test and Dr's office calls back that day WBC at 1,700 and neutrophils 300!! Scheduled me for bone marrow biopsy 7 days later tells me to stop taking Benadryl. Do research on line and see where a rare but severe side effect of antihistamines is what I have just described. At biopsy I tell Dr who has never heard of this effect to redo WBC count before biopsy. He reluctantly does preforms biopsy before getting blood results back. Comes back 20 minutes later and says WBC now at 3,600 and neutrophils at 2,200!!! Can't prove that eliminating the Benadryl 7 days previous caused my WBC to dramatically increase but I believe it was the cause. This is a rare but severe side effect and just my unfortunate luck to be one of those few people who it happened to. M 59 120 days

 3  Sleep aid I also had just under one dose of nyquil, but I was dizzy and couldn't stand up. I couldn't do simple things like type on my phone properly. I would almost fall asleep but the urge to move became too strong to bare so I eventually crawled to the bathroom and laid down on the floor until I felt better. Definitely put me to sleep although I may have taken a couple more tablets that necessary. Would definitely use again. (But I recommend using the correct dosage unless you have a bit of a death wish like me) F 16 1 days

 3  For hives/itchiness from sun rash. Drowsiness, numbness and tingling sensations through arms and legs, almost in a trance, slurred speech, dizziness, felt as though my heart was barely beating, random muscle spasms, ect. I was left with a horrible sun rash (first I've ever had) after being in the pool for a long time. My mom, as well as our family doctor, told me to take some Benadryl for a few days to help with the itchiness and swelling. It helped the swelling, and a little bit of the itchiness.. But the side effects that came with it are worse than how I was before I took the pill! It was so hard to lift my own hand, and it was like I was an empty shell, as I could barely feel my body. Let alone, it knocked me out, and I've basically been asleep for the four days I've taken it! F 15 4 days

 3  Reaction to platelets I feel just so out of it when I get IV Benadryl. The first time I had a reaction to it, I couldn't even lift my arm. I also couldn't stop laughing for some reason. The nurses were quite concerned. The nurses now reduced my dose to 20mg and push it over 20 minutes. That makes every thing less severe. It makes reactions go away, though. Lie down if you have to take it! F 14 10 times

 4  Helped me get off of slow weaning x I feel a general head buzz and pressure behind my eyes. I think my blood pressure goes up and I notice I have a disconnect of my hands like when I try to straighten my bed clothes..I just cant make my hand work! Its weird! I also have heightened sexual feelings and orgasms are intense!(Nice side effect)I have intense feelings of horror though when I see someone getting killed in a movie or something. I internalize it. Its quite frightening. Over all, I would recommend it for a sleep aid as its non addictive and give quite a calming feeling. F 59 1 years

 1  Post Nasal drip, Allergies & Sleep None at first, but after continual use I was diagnosed with Rosacea, sometime had very dry skin that cracked, some hair loss, lower libido, increased breathing issues sometimes (thought it was my asthma), inner ear pressure and problems hearing with tinnitus, numb toes and hands, foggy head, severe memory loss/ forgetfulness, mild depression, tension in neck (thought it was from old injury), inability to relax, pounding heart for no reason during day, chronic fatigue (diagnosed with narcolepsy), extreme irritability, blurry vision which occurred occasionally but not always (my ability to focus changed when I increased the dose). Side affects appeared several years into continual and increased use. I wish that I had known sooner. I do not know if my early menopause was caused by it and if I will have permanent memory issues now that use of this medication was linked to dementia. I stopped taking it 2 days ago and my calve muscles hurt very bad like I pulled them. DO NOT USE THIS DRUG, I took very small doses of Benadry over 20 years, maybe 3 MG each night and did not experience really bad side effects. I felt like I was in a fog sometimes but was able to sleep and function without problems with my post nasal drip which is extremely bad and triggers my asthma. In the past 3 years I increased my dosage and did not realize that the medication was affecting me. It is a horrible drug and I did try to find information, like is on this site, but did not find any negative information. If I had, I would have stopped taking it altogether years ago. F 50 20 years

 1  Allergy Related-Symptoms: Watery ey Two decades ago, when I took Benadryl for allergies such as watery eyes, itchy related symptoms, I experienced fast heart-beat rates. About two weeks' ago, I decided to try after having problems with other Allergy medications and nose sprays, this time, it prevented me from completely able to sneeze. Whenever, I tried to sneeze, I was unable to do so in its entirety. Also, two decades ago, my son, 3 at the time, experienced an alarming side-effect from the Benadryl Suspension prescribed. He was unable to urinate until later even with his pediatrician and an urologist's interventions. After the fast heartbeat rates in the past and my son's experience, I promised that I would never take Benadryl again. Moreover, I took a pharmaceutical drug class, which I learned that my experience and my son's experience, are some of the side-effects of Benadryl. Further, it did not completely treat all of my allergy symptoms; my itchy nostrils. These allergy treatable drugs seem somehow helpful, but from my and son's experience causes devastating effects.
