    hi I have been taking Benadryl or pet dander? It seemed to work well even if I only take one tablet. Does anyone also find that taking one tablet does not make you drowsy? How often should I take one tablet of Benadryl which is 25 mg? has anyone found any other allergy medication that work or pet dander? Thank you very much.

    Hi, the only support group that I've been able to find for people with insulinomas is located in the UK... just wondering if there is one in the US. I had pancreatic surgery to remove my first insulinoma in 2012, we're thinking there's another because I'm still having problems with hypoglycemia... if anyone know anything, PLEASE CONTACT ME!!! :)
    I know there can't just be a support group here for FERRETS!!! people are kind of important... I hate this song, but "Don't worry, BE HAPPY" is okay, I guess... I'm trying to force it upon myself. Things will get BETTER!!!

  • Does zoloft cause ringing in the ears, like tinnitus? i've been on it for a month and noticed the ringing in the ears about a week ago, and it's just constant ringing and it's driving me insane. (1 answer)
    (Asked by a 24 year old man who has Ringing In The Ears, and takes Dicyclomine Hydrochloride, Benadryl, Tylenol, Lialda, Azathioprine, Prednisone, Ambien, Zoloft)
    I've been on most of the medications for more than a year and it hasn't been that bad getting used to them. But I've been on Zoloft and ambien for about a month now, and I've been noticing a lot of side effects. The one I just recently noticed and that has been driving me completely insane, is the ringing in the ears. It's been about a week now and I just don't know what to do anymore. If it is the Zoloft then I can finally just stop taking it and make this stop. If anyone has an answer or knows what to do, PLEASE help. I'm at my wits end.

  • Had nms in 2005, will trileptal increase chance of recurrence?
    (Posted by a 62 year old woman who has Narcolepsy, Prinzmetal's Angina , Antiphospholipid Syndrome, High Blood Pressure, Obsessive-compulsive Personality Disorder, Cyclic Vomiting Syndrome, Migraine With Aura, Herniated Intervertebral Disk, Osteoarthritis, Fibromyalgia, Rheumatoid Arthritis, Diabetes Mellitus Insulin-dependent, Bipolar I Disorder, and takes Benadryl, Baclofen, Plaquenil, Nitro-bid, Maxalt-mlt, Imitrex, Zofran Odt, Ms Contin, Clonidine, Amlodipine Besylate, Novolog Flexpen, Levemir Flexpen, Halcion, Valium, Primidone, Neurontin, Trileptal)
    In 2005 I had NMS, which was not detected by my drs for 4 months. I'd been on Lexapro & Seroquel for 2 yrs, but was weaned from Lexapro & placed on Lamictal 3/05. Began getting low-grade fevers, which I was told were not caused by the Lamictal. I quit taking it anyway, fevers (along with uncontrollable shivering) continued & got higher. By 5/05 my temps were reaching 105 deg F. Husband said I became combative, refused to go to hospital. Early June/05 he came home to find me wrapped in blankets, with a temp over 105 F. He tried to place me in a tub of cold water, said I was rigid & screamed when he tried to move me. I was in the tub, speaking "in tongues" (his description, I have no memory of this). He called 911, took me to hospital. I woke, no idea where I was or why. After a lumbar puncture & 2 days in ICU I went home. The fevers continued...2 weeks later he came home to find me wrapped in sheets, towels, blankets, with the heat on full (it was in the 90's outside) he called ambulance again. I awoke to find myself under an ice blanket with nurses pushing large vials of dantrolene into both arms, several liters. Another LP, a stint in ICU...this time they told me it was NMS. The dr who dxd me said he was surprised I was alive, & not a vegetable, as my temp had peaked at 109 deg F. I suffered brain damage; short-term memory loss, brain can't control my body temp, my blood pressure went up. An arteriogram showed completely healthy heart & arteries, no plaque at all. I lost all body fat as well as some muscle mass. The fevers continued even after stopping the Seroquel. I visited my PCP for a checkup in 9/05, temp was normal. I started shuddering, my temp went up a full degree every 5 minutes. PCP admitted me to ER, my heart rate was over 272 B/M; they stopped my heart 3 times to "reset" it, which didn't work. I spent 3 days in hospital. Several months later my P doc tried me on Lamictal alone; I got Stevens-Johnson syndrome. I stopped the drug as soon as the signs appeared. I've been untreated, except for Neurontin & Primidone, until my manic episodes became unlivable. 3 weeks ago I went 8 days with no sleep, became psychotic. My P doc gave me Trileptal, which has evened my moods, but I've been getting low-grade fevers (highest was 103.6). Would having had NMS in the past make me more prone to falling to it again with the Trileptal? It's the only new med I've taken in over a year.
  • Leg pain and occasional arm and hand pain
    (Posted by a 69 year old woman who has Lower Leg Pain, and takes Benadryl)
    I started having leg pains at night, lower leg felt like the muscle and bone were being pulled causing sharp pain. It was relieved by getting up and walking but would last most of the night.

    I finally realized after suffering this over and over for months, that it only happened when I had taken benadryl.

    It seems that the benadryl causes it after taking it within one hour, I don't know why I didn't connect this until yesterday. Sometimes, more rarely, I also had arm and hand pain.
