Took just one pill it's now 3 days and I have severe side effects still.Very dizzy,headaches, nasal congestion,ear congestion,feel very weak,extreme fatigue..
Has anyone had these side effects?If so how long before they ended?
Irregular heartbeat, Heart palpitations, dry mouth, insomnia, feeling like I want to pass out, jittery.
I took Allegra 24-Hr. DO NOT TAKE THIS MEDICATION! I feel HORRIBLE after one pill. I had to rush to the urgent care because I felt like I was going to faint. Pulse was 132 - probably because I was I was panicking but I felt like it was the end for me. Please please look into other options. The side effects of this medication are not worth it. Right now I'm trying to flush my system with lots of water because after 19 hrs I'm still having heart palpitations. I'm praying it'll get better at the 24hr mark.
Headaches tiredness heartburn stomach ache diahorrea ibs symptons generally feeling awful
Helped the hives on my scalp but they didn't fully go away but stopping it today after reading all these reviews and realise now why I feel so awful! Going back to drs as this is the first antihistamine I've taken and the first time I've had chronic hives.
Omg!!! Awful drug! Caused leg and arm weakness, nausea, weight loss, brain fog, dizziness, pain in body mainly neck, shoulders and back, depression, not feeling well, withdrawal has been awful..same symptoms but even more intense. It's been 6 weeks going through cold turkey withdrawal
I had insomnia, brain fog, severe pain in head/neck/shoulders, and anxiety Could not focus on anything. Tired but could not sleep. Detached feeling overall. Almost headed to the ER
I do not recommend taking this medication. I had no prior health or anxiety issues.
Allergies / Getting Allergy Shots
GI Upset, increased anxiety, sleeplessness, low mood.
I had been taking Zyrtec for years and my allergies were not being well controlled. A visit to an ENT ended with them having me switch to Allegra and then start allergy shots. At first, this was a miracle med because it stopped my allergy symptoms. But now, it's caused more problems then is solved. I take medication for GAD and for the past 2 weeks, it's felt like I have missed doses of that medication. I am irritable, waking up with a flood of anxiety, and unable to deal with normal day to day situations that before I could handle with ease. I've had stomach pain, diarrhea, and cramping after every meal, and just all around feel lethargic. I stopped taking this medication, and each day it's gotten better. Be super cautious before taking this and monitor your side effects.
jittery, increased post nasal drip, felt irritable
It has side effects with NO benefits
cough cough and cough! After take 1 pill (24hrs) I start to develop a new cough. I cough every few minutes. My throat feel dry and itch. Can't wait for side effect subside.
I had mood swings, fatigue, muscle weakness, INTENSE back pain like I've never experienced before and I have spondyloarthritis too. I also developed weird nerve pains, tingling in random places on my body. As I've stopped, withdrawals are rough (achy, super itchy etc) but im starting to see improvements. Never want to take this again.
Palpitations, paranoia, depression, anxiety, vertigo, indigestion, severe insomnia
I will never touch this drug again. I got between 0 and 3 hours a night sleep, have had vertigo so severe that I nearly fell over yesterday, have been panicked and stressed, etc.I found it slightly more effective for stopping hay fever but my god is the price high for it. I'll be returning to Loratidine, which has never had such negative side effects for me.
Dry mouth and inside mouth ulcers.
Thankful to have found this site. I thought I was really "losing it". I have taken Allegra every year without side effects, but in the last two weeks of taking it I have: had severe mood swings, felt like I was on the verge of crying all the time, have had a sense of impending doom, felt severely depressed, had very high anxiety, panic attacks, labored breathing, constant hunger, muscle weakness, brain fog, felt detached from my body/reality. I am SO glad I made the connection that it could possibly be the Allegra and started my Google search. (Also, to be clear.. This was Allegra 24 hr, not the Allegra-D.)
Dizziness, nausea, lightheaded, blurred vision
2 year old daughter took Allegra for allergies and soon after started. These were very severe emotional upset, and stopped as soon as I took her off the Allerga.
I just felt down right weird, like I was sleep waking or something it helped my runny nose but it is definitely too strong for me. I don't usually take medicine so it was just too strong. It was supposed to be the non drowsy formula I second that I was sleepy about 15-20 minutes after taking the this 1 pill! I'd rather just suffered through my nose than to take this medicine.
Please READ SIDE EFFECTS BEFORE TAKING
Took for sinus pain and headache. Made me very sick ! Shaking, jittery, chest tightness, heart racing, dizzines, face hot with cold sweats. Nausea, diarrhea...etc.In bed all day after taking 1 pill!! Never again!!!
Runny nose and sinus congestion
Fortunately I wasn't driving, started to get abnormally dizzy and lightheaded, with chills and cold sweat, nausea and vomiting, extreme weakness and loss of speech control! Called poison control since that's all I could find online and was told I shouldn't be sick and that they'll call me back in two hours to check on me! The dosage of this medicine is extreme and very unnecessary and I wish I had read these reviews prior to taking it! Never again 👎ðŸ»ðŸ‘ŽðŸ»ðŸ‘ŽðŸ»
Don't sell these at gas stations such as Quick Trip without a doctor's prescription!!!

Easier to get stressed. Chest spasms and lump in throat.
thought it was going to be a drug I could tolerate. 3rd day..heart palps...terrible stomach and abdominal pain....stopped taking it and still heart palps 3 days later
After reading all of these posts, I am seeing everything more clear. I switched from the Nuva Ring to Microgestin 1/20 FE.I have had horrible breast tenderness up to two weeks before my period?!?! I noticed my face has gotten some what oilier, I feel as if I have gained 5 lbs. Mood swings are swinging away, short tempered and I seem to anger more easily. I think after my last pill on July 2nd, I will be dicontinuing this pills. When I was on Loestrin and not this generic I was fine. Maybe it's the just the generic? What pills have you switched to from Microgestin?
Ridiculously expensive!I was paying less than $10 with my United Healthcare plan for Simvastitin, now pay $150 for same 30 day prescription!
I have chewed Nicorette gum for 11 yrs, I have had to have filling's replaced, after about 8 yrs I noticed I started losing hair, and then I ended up with heartburn. I decided to quit the gum, by going on a lower dose of the nicotine patches( advice I got from another post) and it has been 4 day's now without the gum, and I'm feeling good. I thought I would miss chewing it, but when I feel the need I just take a piece of regular gum. Today I even forgot to change my patch. So I know it won't take long and I will be nicotine free forever!
The number one side effect that I had instantly was feeling tired, weak,sicl to my stomach and at times vomitting without warning.I did notice that my sense of smell went to the roof. I could smell things that noone else could. Almost like a pregnant woman. When I first started Byetta in Feb of this year the first two to three weeks were horrible. I talked to my GYN and said to take tums and if needed take Zofran for my stomach. After the medicine got used to my body, the side effects went away and was able to eat an hour prior to a meal, without problems. If you go off your dose for a while, you experience the side effects all over again. That's mainly why I took so long to get back in the groove of things.
Extreme muscle fatigue(suspect Rhabdomyolosis) leading to tendonitis as a result of trying to perform normal physical work related duties. Just starting to regain strength after 16 months.
I still have trouble determining if this is working for me but I think it is. I tried 30mg today and seems to be a good dose. Will see what happens when I don't take it tomorrow. Hope I don't have to go higher. I notice a slowing down in my movements and my thoughts (long enough to think before speaking). Dexedrine also helps me relax. Interesting how this works. There's still so much I don't understand.
Drowsiness at first, but it went away after a couple of days. Constipation was so bad, no movement for a week. I had to take Metamucil.
Does make you sick for a short duration, but if they give you they nausea medication first and you lie still it helps. It's just a sicking heavy weight feeling.I also have severe pain from DDD, arthritis, fibromyalgia...etc...and it helps that as well.
