 1  seasonal allergies Age & gender are actually my husband's. This drug is ruining our marriage, my sweet, laid back, Godly man has turned into a demonic tyrant. We are so close to losing our marriage over sleeplessness, mood swings, & imaginations of malice. He hasn't been able to quit because the hives are so bad. But he has to quit now or our life will be ruined. He's down to 1/4 pill every other day. Those days are the demon days. The off days are when I get to see my husband again. M 34 2 years

 3  Pet allergies Totally exhausted like I haven't slept at all when I did - just dragging to get through the day - major brain fog. Body aches from head to toe. My mild mannered husband is also taking it and he has show restlessness, sleeplessness, and extreme irritability over small issues - so no like him at all!! Bought the generic brand from Wal-Mart. So glad I didn't buy the huge bottle. It did help the stopped up hard to breath issues but it's not worth taking with all the side effects. F 47 7 days

 3  Allergies Weight gain, overeating, craving sugar, mild ear infection, dry mouth I get GI disturbances when I go off this medication, my eyes have been red and dry ever since I stopped taking them. Allegra works better and it doesn't contain any lactose like reaction does. Reactine works better than benadryl for me however I don't like the side effects. Will start taking Allegra again or something natural instead. F 28 6 months

 3  Allergic rhinitis 25 lb weight gain, slowly over 5 years- last week I read something about Zyrtec causing weight gain and it finally clicked for me- I've been going mad trying to figure out the cause of this weight, despite eating a very clean/moderate calorie diet and exercising regularly- nothing else changed in my life to cause this. Zyrtec actually worked extremely well for me- I'm a lifelong sufferer of allergies, allergic to everything, 8 shots/week for years- Zyrtec + Flonase at night gave me my life back. Was able to breathe through my nose again, didn't suffer wheezing/itching all the time, slept so well. But now that I've learned that it may be the cause of my weight gain, I stopped taking it one week ago to see if the weight will drop off. I feel awful- insomnia finally waning, wheezing, stuffy nose, and extreme histamine reactions to foods causing swelling of the tongue and throat- food I ate daily with no reactions whatsoever. If weight doesn't drop I'm going back on it. Either option is awful- fat or miserable. F 46 5 years

 1  Allergic Rhinitis My 9yo boy was advise by his pedia to take Cetirizine for 7 days, 1 tab/day, and since he started it he's having a terrible nightmares, he almost told me he's not happy with his life anymore.. what the ***.. I was terrified and it's not his usual sleeping behavior.. so on his 3rd day I stopped giving him this tablet.. and he had a very nice sleep.. no nightmares.. i tried to give him again on his 4th day.. then he had the nightmare again.. so I believe it is the drug causing him all of these bad dreams and confusion... BEWARE OF CETIRIZINE be it generic or branded like Zyrtec.. it gives the same worst side effects! M 9 4 days

 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
