About this FactMed analysis covering adverse side effect reports of ALLEGRA patients who developed ACHLORHYDRIA.

FactMed provides MD-approved analysis to help both patients, researchers, and physicians accurately assess the risk profile for more than 20,000 different pharmaceutical products. The below report offers compiled information from Food & Drug Administration and FactMed user submissions. Between January 2004 and October 2012, 1 individuals taking ALLEGRA reported ACHLORHYDRIA to the FDA. A total of 15572 ALLEGRA drug adverse event reaction reports were made with the FDA during this time period. Often the FDA only receives reports of the most critical and severe cases; these numbers may therefore underrepresent the complication rate of the medication.

FDA Research Report

Introduction This page is designed to help you determine the relationship, if any, between ALLEGRA and ACHLORHYDRIA.

QUESTION
WAIST CIRCUMFERENCE INCREASED
I have been a petite healthy fit woman all my life. I am 44 with two kids ages 19 and 14. I have been a vegetarian all my life with a rock star model figure until earlier this year when my allergies started. I started taking Allegra, and have been doing so this past entire year. I have noticed a significant increase in my waistline as one of the major side effects, along with bloating and gas trouble. 2014-11-19 12:25:16
QUESTION
OSTEOCHONDROSIS
Taking prescribed Allegra for approximately 8 years for allergies at ages from 42 - 50; Male, athletic, 5'9", 160 lbs, competitive swimmer with no former back related issues. I was having periodic episodes of severe (debilitating) lower , lumbar back pains that would flare up every two months or so. This resulted in years of chiropractic treatments and physiotherapy. At approximate age 51, after seeing an Allegra TV commercial indicating a major side effect was "lower back" pain, I stopped using the drug with almost immediate elimination of the back pains. Ten years later, after a recent MRI exam the diagnosis was : Degenerative changes of the lumbar spine with signs of osteochondrosis activated at LWK 4/5 and smaller prolapsed disc (NPP) to median mediolateral left at L5 / SWK. 1 My question is has there been any evidence or study indicating a relation between prolonged us of Allegra and this condition? johnprest@gmail.com 2015-03-23 09:04:01
QUESTION

RESTLESS LEGS SYNDROME
I tarted taking allegra d about 8 months ago for allergies and now have started having rls, is there any connection 2016-03-21 06:01:41
QUESTION
RECURRING SKIN BOILS
I took allegra for years. It helped my allergies better than any other med. After the first frost in 2015 I stopped taking it. In the spring I ran across Claritin and tried it. It was good until the Crepe Myrtle, grass, and ragweed got heavy in August. I returned to my allegra. 1 week after starting Allegra the following returned: Lumps/boils from my ear to my neck including down my jawline, fluid in my knee caps, severe joint pain, restless leg, night terrors, waking up to 15 times during an 8 hour sleep, and needless to say, exhaustion and irritability. Prior to ending my use of Allegra I was under Doctor's care for all of these things, and had stopped most treatments because they were better. Imagine my surprise when they all flated up 7 pills into Allegra. Now I am 4 days off of Allegra and 24 hours into a 48 hour clense/detox fast and feeling 80% better. My hope is that this helps someone else and they do not suffer 7 years as I did. 2016-08-20 21:05:43

TARDIVE DYSKINESIA
My allergist recommended that I take extended-release Allegra once a day on a consistent basis to provide relief for year-round allergies. What is the risk of tardive dyskinesia in so doing? 2017-08-18 16:10:47
QUESTION
TINNITUS
I began taking Allegra Allergy due to rashes and itching from too much histamine in my body. It seemed as though the Allegra increased the loudness of my tinnitus and made it that way all the time. 2017-08-30 13:31:27
CONCERN
ARTHRITIS
I am 67, a woman, and took Allegra for approximately 6 months. During that period I developed anxiety and I noticed that my dexterity seemed to be slightly off. Being very active with my hands sewing, knitting and embroidery it was quite apparent that there was something going on. I just didn't feel right, my arms felt lightweight and a bit like the hair on them was standing up. I also began waking up in the morning with a nasty backache in the lumbar region. I notice that my joints were achy when I got up from sitting for a short while and that my hands and wrists especially ached from use, etc. Finally I did some internet research (even though people always warn about the internet) and discovered on a blog there was a woman who developed similar symptoms that I had while taking Allegra, how they had stopped or decreased when she discontinued it. So I did just that. After 8 days the backaches have stopped. Within 10 days I began to notice that my hands were better. This has not completely subsided and I am just hoping that is isn't going to be a permanent side effect. 2017-11-16 11:05:16
