For Nausea/Vomiting "I have emetophobia, that is, a pervasive fear of vomiting. I do not know if this affects vomiting, but if I feel nauseous, Benadryl works wonders. My stomach settles right down and my anxiety lowers just enough for me to deal with it without the use of benzodiazepines."

For Allergic Reactions "This is an old thread but thought I would share. I was in the hospital in labor. I developed a reaction to the epidural that caused severe itchiness. They gave me something that didn't help, and after several hours of itching, a nurse gave me IV Benadryl. I immediately couldn't breathe and felt like someone kicked me in the chest. I was warm all over, nauseous, and on the edge of passing out. An EKG also showed I had a heart arrhythmia from it. I've taken oral Benadryl in the past with no problems. Now it's on my list of allergies, and I tell every doc I see. Most terrifying experience."

For Allergic Reactions "I have no rest every time I take Benadryl. I feel I have a really bad reaction as I feel restless, my body feels itchy, nauseous, and it makes me feel angry. Feeling restless really hurts my stomach. Am I allergic to it, or is it a bad reaction?"

For Nausea/Vomiting "Took Benadryl when I was out of town and did not have my generic brand Equate with me. I had done this twice, and both times, the Benadryl made me sick with diarrhea and nausea. I will always stick with the Equate for hay fever, as I never feel sick from it."

For Nausea/Vomiting "I take Methotrexate weekly, 25 mg, and have found that taking Benadryl at a dose of 12 and 24 hours after my weekly dose helps reduce the nausea."

For Nausea/Vomiting "I used it originally for food allergies but ended up puking (expected, to be honest). Not long after, I took another to wave off the extra symptoms like nausea. All it did was induce vomiting again."

For Nausea/Vomiting "I took a single pill of Benadryl, and it made me vomit, nauseous, diarrhea, dry throat, and gave me a stuffy nose. I wouldn't give this to my worst enemy."
