 1  Cetirizine* for fluid in Ear I was prescribed This for fluid in my ear. First day seemed ok, a bit dizzy but doc said that was from the fluid in my ear. Day 2 had a panic attack just sitting on my couch. Got very dizzy felt like all my air was taken away, then I got very cold and my legs began to shake, I fell asleep for about an hour and when I woke up I just didn't feel right. Like I was in a haze, almost like drunk and still feeling dizzy and my legs felt heavy. I didn't take anymore and it took almost three days for me to feel normal again. I thought I was crazy until readying these reviews, I'm pretty sure it was the drug now! I would not recommend this drug. F 33 2 days

 1  Originally for hives Zyrtek is a toxic, addictive-like drug that should be ripped off of the market!!! I began taking it after a trip to the ER. It came highly recommended for my problems and I was completely allergic to Benadryl. Not only did I go from 112 pounds and pack on 20+ (Different each day due to severe water retention and swelling), but getting off this drug is torturous!!!!! Withdrawal symptoms include; more severe hives, angioedema, burning, all over and traveling itching, central nervous system taxation, chills with burning, need I go on????? This product disgusts me. My life is highly affected by the I'll effects of the fact that Zyrtek wants you to Rely on it in order to live, but you cannot live freely. F 34 1 days

 3  ALLERGIES gained 30 pounds(can't get the weight off no matter how much I work out), very tired all day, trouble sleeping, weird dreams, more hungry late evening/night helped my allergies, but now that I have read about the awful side affects and realize my unusual weight gain is probably from the zyrtec, I am going to quit taking it and see if all of my exercising and diet will finally start showing results F 33 8 months

 1  Allergies Doctor sais this will really help you. Ummm, NO! Felt like I was high! Took this stuff before bed. Woke up and could barely get out of my bed. Felt completely out of it like I was floating. Sat on the couch and my partner asked if I was okay. I yelled at him! That is so not me... It took almost all day for me to get off the couch. It has been 15 hours since I took this and it is just now barely starting to wear off. Be very careful if you decide to take this stuff, I guarantee you I never will again, it's not worth it.

 1  Seasonal Allergies Started Zyrec for seasonal allergies. The third day, my allergy symptoms were better. I was home alone, and stood up. Could not stand, as my legs and arms were heavy and the room was spinning. Terrified, I ran outside, so that a neighbor might see me and help. No neighbor around. I sat down, until it stopped, and stood up. Started again. Fortunately there is an emergency clinic about two minutes from my house. I hopped in the car, said a prayer, and drove there. They thought I was having a heart attack. Did an EKG. Nothing wrong. It was the stupid medication. Stopped it, and it took a couple of days before I felt myself again. Allergies returned, but I will deal with them naturally, as I cannot afford the medical bills that using Zyrtec, for only THREE days, cost me. DO NOT USE THIS DRUG. IT'S DANGEROUS. Should be taken off of the market. F 59 3 days

 1  Allergies I recently moved to Texas and have been dealing with allergies for the first time in my life. I took half a zyrtec in the morning 2 days ago and FAINTED later in the day. It was terrifying but luckily someone caught me before I could hit my head on the concrete. I looked on the FDA site and read that 1.6% of users experience fainting as a side effect. F 27 1 days

 1  Severe allergies: pets & seasonal Shortness of breath. Irregular heartbeat. Anxiety. Depression. Insomnia. Lack of focus. Drowsy. This helped with my allergy symptoms, but the side effects are not worth it. I felt like I was having a heart attack or asthm attack at times. Very scary. Beware of Zyrtec! F 23 7 months

 1  Seasonal allergies I stopped taking cetirizine 5 days ago, the first night was horrible, itch all over my body, I took one pill of allegra 180 mg and all the symptoms were one, I kept having 1 pill of allegra for the next 3 days but I want to stop it today, I am itching but not so bad now, I'll see what happen when I stop taking allegra. I guess I can not take any medication at all, every time I take one I get so many symptoms that are way worse than the reason I am taking it. Anxiety, panic attacks, social phobia, and I also lost my hair, I feel like I have aged 10 years since I started this medication. Too bad I did not make the connection before. F 47 1 years

 5  Rhinitis Helped me with dry itchy eyes. And constant rhinitis. No side effects that I'm aware of. My right ear always had fluid in it during allergy season which makes me more susceptible to cold and flu viruses Zyrtec helps keep inflation to a minimum. F 50 10 years

 1  Allergies Helped the first day. However the second day... HORRIBLE rapid, uneven heartbeat, random panic attacks before falling asleep (seemed to have zero control over), anxiety, jumpyness, restlessness. I honestly got no sleep at all the second night, and I am a college student so the next day was awful as well. Like the woman above said, I HONESTLY THOUGHT I WAS DYING. Doooo NOT take this!

 3  Bug bite weakness, fatigue, depression, anger I took 1 10mg Zyrtec gelcap two days in a row to reduce the swelling of a baseball-sized bug bite on my leg. I took each dose before bed, and the swelling was greatly reduced by the morning. I was feeling more tired than usual during the day, but I was out of town for work and chalked it up to travel exhaustion. I took one again last night (two days after the second dose) and felt extremely combative with my boyfriend and had trouble falling asleep and staying asleep. This morning I still felt angry and was having lots of doom and gloom thoughts. The anger transitioned into depression and feeling physically like I had been run over by a steamroller. I wondered if I had caught the flu. I took a 2-hour nap and when I woke up, I could hardly move my body. Am feeling a bit better, although still a little off, almost 24 hours after the last dose. I'm disappointed because Benadryl tends to cause rapid heart beat and anxiety attacks for me, and I thought Zyrtec could be my go-to. F 27 3 days

 1  Seasonal Allergies Intense rage, anger, and mood changes. Started taking Zyrtec in May to combat seasonal allergies. Last year was extremely bad for me, so I wanted to get a head start on anything that would stop me from being miserable. After a few months of taking Zyrtec I started getting uncontrollable rage and anger when mildly arguing or confronted by friends, family, and co-workers. The rage and anger was so intense, it even scared me. During an argument/fight, I would seriously want to physically hurt the person I was fighting with, something that I have never truly felt. I sincerely thought I was losing my mind and going crazy. I've never felt that kind of anger. I went to my doctor and explained what was going on - I assumed it was hormonal and connected to my periods - it HAD to be! Next I was referred to a psychotherapist for changes in mood. Was told it was the stress at my job, anxiety, etc. When my allergies never really came about this season, I realized I should just stop taking Zyrtec - what's the point if I'm not sneezing/miserable? So, I stopped taking Zyrtec for about two weeks. Then I took Zyrtec randomly one evening after sneezing all day and the next day I was a crazy, psychotic, rage monster. It was then that I finally realized the correlation between the drug and my mood. I have been off Zyrtec for about one month. All rage/anger/mood change symptoms are gone. This drug should NOT be OTC. It took away two months of my life and made me feel beyond crazy. I never even considered that allergy medication could e F 33 3 months
