| 1 | common allergies: dust, pollen, etc | It relieved my runny nose, sneezing, and itchy eyes all of my life. When I would miss a dose I would feel itchy all over and we believed it was just my allergies surfacing so I would take my medicine and feel better. I was at a 5mg dose for the first few years and then bumped it up to 10mg. Once, when I was about 14, I was on vacation for a few days and realized I forgot my medicine at home but figured it shouldn't be the end of the world and that I would be home soon enough. Instead, after a few days without zyrtec, I woke up in the middle of the night with a terrible headache and nausea. Of course these withdrawal syptoms were on top of the unbearable itching that feel like bugs under my skin accompanied with scratching that leads to my dermatographism making my body one giant welt. Anyway, I took some tylenol for the headache and bought some zyrtec the next morning and felt fine. I officially started my final withdrawal a week ago and if my nose is runny I take a claritin. There is nothing that will surpress the itching which is the worst part. I have found that the key to making it so long is resisting the urge to scratch. Once you start scratching its all over. Previously, 3 days has been my longest time without giving in. Staying active and busy helps take your mind off the scratching and benadryl is a good way to knock yourself out when its unbearable. And if you start itching, rub an ice cube on the area or take an ice bath or cold shower. Good luck to everyone like | F | 19 | 10 years 10 mg | 1/2/2012 | 1 | Hives | Strong food cravings which caused weight gain, digestive problems and fatigue. | I do not recommend Zyrtec. I got stomach cramps and diarrhea. I had strong food cravings and therefore gained a lot of weight within only two weeks. I was also really tired during the day and had to take hour-long naps. I started taking Zyrtec together with Prednisone. After I stopped the Prednisone the side effects did not stop and acually got worse, plus the hives came back. After I stopped taking Zyrtec the sympoms dissappeared, but the hives were better than before I started taking any medication. My experience was that the hives were stress related and it has gotten a lot better since I accepted having the hives and do not have so much stress anymore. | F | 19 | 2 weeks | 2/13/2007 | 1 | Allergies, pressure in my ears | Brain fog, hard to remember things, feeling in a daze or cloud all of the time, anxiety, crying | I thought I was going crazy until I read these side effects every body else has had from Zyrtec. It's made me feel horrible. Can't remember anything, in a constant haze, emotionally unstable, bad anxiety... Would NOT recommend. | F | 19 | 1 weeks 10 | 6/3/2020 | 1 | Runny nose | It gives me a trippy feeling. Tremors are present in both arms and legs (especially the legs, and it also made them very weak that i can barely even walk). Makes you sleep in the morning but prevents you doing that at night. Also loss in apetite | M | 19 | 2 days 10 2X day | 9/23/2017 | 1 | seasonal allergies | body pain dizzines Weight GAIN anger issues | i was a model since the age of 16. i had a horrible allergies that i had to take zyrtec 10mg to treat. i started gaining weight from no where! and zyrtec was the only medication i was taking. and finally i decided to search about this med and i found out that every single negative symptom i had\have is because of this sh** med!!!! never ever taking it again! gained 40lb in 2 years had a serious anger issues | F | 19 | 2 years 10mg | 4/8/2015 | 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! | F | 19 | 2 days | 9/3/2014 | 5 | Allergies | None for me. They told me that I'd possibly experience drowsiness, but I got no side-effects whatsoever. | I love this stuff. It works miraculously. I'm allergic to cats and I have six, so I pretty much have to take this every day, or whenever I feel an allergy attack coming on, and it just works so well. My only complaint is it being OTC now so it's MUCH more expensive, but I just get store-brand, and it works just as well. | F | 20 | 8 years | 1/31/2009 | 5 | Hives | DEFINITELY A 1! DO NOT TAKE THIS MED~ After taking zyrtec for about 3 years now i have finally been able to put everything together. I am constantly sleepy and i dont enjoy participating in a lot of things b/c of this. I was just put on depression medicine about 4 months ago. Bloody nose, irritable, always taking naps in the middle of the afternoon, some weight gain, ALWAYS HUNGRY-NEVER SATISFIED. DO NOT TAKE THIS DRUG IT DOES NOT LET YOU QUIT. I HAVE NOT TAKEN IT NOW FOR 4 DAYS AND I FEEL LIKE HELL. THE ITCHING IS DRIVING ME TO TEARS. I DONT KNOW IF I WILL BE ABLE TO CONTINUE NOT USING IT B/C GETTING OFF OF IT IS SO HARD. | IT DID MAKE MY HIVES GO AWAY. BUT YOU PAY A HUGE PRICE. | F | 20 | 3 years | 1/11/2007 | 3 | hives | Extremely increased anxiety, difficulty falling asleep, difficulty waking up. However, it leaves me functioning enough to go to classes, which Benedryl did not. | I am on double the over the counter dose due to the severity of my allergic reaction | F | 20 | 4 weeks 10 MG 2X day | 4/8/2013 | 3 | Allergies | Dry Mouth Very Random Dry Skin | I had pretty bad Allergies back in late High School and Zyrtec was the only thing that cleared it up, but you have a constant dry feeling for some reason. Not even drinking large amounts of water fixes it either. | M | 20 | 2 years | 12/13/2005 | 2 | Allergies | This medication made me so drowsy that I couldn't function during the day. I would stumble around almost in a trance. | It helped my allergies to a degree, but the extreme drowsiness it causes isn't worth it. | F | 20 | 5 days | 5/24/2005 | 2 | allergies | spacy during the day, and sleepwalking at night from drowsiness right before I went to bed | F | 20 | 1 years | 11/6/2008 | 1 | sinusitis | dissociation, abnormal thinking, nervousness, depression, rage, hallucinations, apathy (basically i felt crazy and maybe i was) | zyrtec was pure hell for me. my thinking became extremely obsessive and i was really tense all the time. i felt emotionally detached. after a few months i lost my motivation, and became depressed. then something really scary happened... auditory hallucinations. i heard a voice in my head. STAY OFF THIS DRUG IF YOU WANT TO KEEP YOUR SANITY it ruined my life! | F | 20 | 6 months | 11/17/2005 | 1 | Allergies | Increased Anxiety, Depression, Mood swings, Decreased appetite, Nausea, Feelings of hopelessness. | I have taken this drug for almost a month, and I have a history of being sensitive to medication. About 1 and a half weeks after taking this medication, I noticed I started to develop anxiety towards going to work and even anxiety about having an anxiety problem (if that makes sense). It has progressively gotten worse as the blood level has increased. I find myself not looking forward to anything in life. My anxiety is very labile and goes from being very anxious to calm within a matter of seconds. I find myself only eating a few pieces of toast for breakfast and nothing else until dinner. I am a RN and I find this a crime that these severe side effects are not explained more blatantly. It took me a while but I realized that all of this is due to the zyrtec, because I have never experienced these types of feelings before in my life. I took my last dose this morning and am going to see my PCP tomorrow to get his opinion on all of this. | M | 20 | 1 months 30 1X day | 12/3/2012 | 1 | My 1 year old daughter was having allergy problems so I took her to the doctor and they prescribe this to her also. I gave it to her that next morning. Within just a few hours, she started getting tired. Which i just figured it was nap time. She woke up about a hour later. Her eyes were so swollen and blood shot, coughing and sneezing worse than before, tired, weak, couldn't eat and even when she would try, she couldn't keep the food down. So i automatically figured it was the med. So, i threw it away and never gave it to her since and never will. Since then, she's been the normal, sweet little girl. | I recommend this product TO NO ONE!!! | F | 20 | 1 days 1X day | 3/24/2010 | 1 | allergies | zyrtec gave me severe depression, false thoughts, angry behavior, mood swings, feelings of suicide, and i cried all the time. worst 5 weeks of my life. the prescription zyrtec never effected me as much as the over the counter stuff just started. DO NOT TAKE> | M | 20 | | 8/31/2008 | 5 | Year round allergies | I haven't experienced any noticeable side effects. | I have been taking zyrtec for about 3 years. I am allergic to trees, grass, weeds, dust, mold, and animals. I had never been able to sleep with my mouth closed before I took Zyrtec. I also had very sensitive skin which was almost always itchy and would welt up when I scratched it. I couldn't wear any kind of lipstick/chapstick with color or flavor because it gave me a sore throat and made the area around my mouth turn red. Zyrtec has not completely cured my night breathing problems, but it has made them tons better. The biggest difference is that I am rarely itchy. it used to be that once I started scratching, I couldn't stop and sometimes, I would end up bleeding. I am so happy not to have to worry about that anymore. My skin still welts up if I scratch it, but I hardly ever do. I also don't have to worry about wearing chapstick or lipstick. On top of that, my seasonal allergies have gone away. Zyrtec has been great for me. | F | 21 | 10 mg 1X day | 4/29/2010 | 5 | allergies | moodswings, drowsiness | I've been taking Zyrtec off an on for seasonal allergies since I was a kid. It's the only thing I could find that really helps with the minimal side effects. HOWEVER, If i take zyrtec too late a night i just cant get up in the morning. so obviously i suffer drowsiness with it. Also, I get really moody and sensitive a few hours after taking it. I find taking it at about 8 PM is best.. I'm asleep before the moodiness sets in, and I'm able to wake up on time. Abiding by these rules I'm fine with it | F | 21 | 13 years 10mg 1X day | 9/13/2010 | 5 | Year round allergies-Pollen | Drowsiness-But just take it at night time and you will be fine. | The ONLY allergy pill that worked for me. I LOVE it! | F | 21 | 10 years 10MG 1X day | 10/12/2011 | 4 | allergies | lethargy/exhaustion, increased appetite, weight gain | I have been taking Zyrtec almost every day for the past three months. It has worked very well overall so far, even controlling my allergies when the pollen is really bad. For about the first month and a half I was really exhausted, but unlike Benadryl it doesn't make me totally out of it, so I can deal with being somewhat exhausted now. But after gaining at least 15 pounds in the past three months (and I'm one of those people who can *never* gain weight), I decided to look it up online and discovered a lot of other people have been having the same problem. | F | 21 | 3 months | 7/18/2006 |
