| 1 | allergies | extreme exhaustion. starving. confusion. mood changes. irritability. LETHARGY. | i cannot believe an antihistamine could have this affect on me. i am usually able to overcome any lethargy caused by benadryl, for example, but the exhaustion from zyrtec is disabling. plus i can't think straight. i feel crazy and like nothing is real. maybe this forum isn't even real. i am sad. usually i am happy no matter what. i am annoyed with the universe. i would rather feel ANYTHING than this. i will never take this drug again. | F | 30 | 4 days 10 mg 1X day | 5/21/2010 | 1 | allergies | After only taking this medicine once, I expericed stomach pains,sore throat, runny nose, pressure build-up in my nose,and inability to sleep through out the night. | F | 12 | 1 days 10mg 1X day | 5/19/2010 | 4 | seasonal allergies | I've been having the most bizarre, vivid dreams--some quite scary. I've also felt a bit depressed and have been extremely gassy. I figured the dreams might be a result of the zyrtec, but I didn't connect the depression or the gas until I visited this site. I've also had minor irritability, though it would be hard to definitively blame the zyrtec. | My seasonal allergies are almost nil. This is the best spring I've had since I moved to Michigan five years ago, and I've been hearing LOTS of people complaining about how bad it is this year. | F | 41 | 6 weeks 1X day | 5/18/2010 | 1 | Seasonal allergies | Most severe: Extreme fatigue, extremely severe dizziness, inability to remain asleep, vivid/disturbing dreams. Less severe: Mood swings (sad to angry and back), mild depression, inability to concentrate for long periods. | The fatigue and extreme dizziness were the most debilitating side effects. Upon rising from bed, I was so dizzy that I actually fell several times before making the connection to Zyrtec and stopping it. I slept poorly and no amount of sleep would reduce the severe fatigue. Dizziness was worst upon rising, but was persistent to a lesser degree throughout the day. Mood and concentration may have been a side effect of the drug and/or the poor sleep and fatigue. Sadly, it does seem to work better on my allergies than anything else I've taken, but the negative side effects FAR, FAR outweigh its benefits. Symptoms resolved themselves within 2-3 days of stopping the medication. I'll just have to buy tissues and suffer. My nose may run, but at least the room won't be spinning all the time. | M | 45 | 45 days 10 mg 1X day | 5/18/2010 | 1 | allergies | my daughter is 4 and she has been taking zyrtec for about 1 year for allergies, I recently noticed that whenever she would have a "meltdown" it was after getting zyrtec. I began to watch more closely and definitely pinpointed it to the zyrtec. She goes into almost a complete rage and becomes a totally different person. I was referring to it as a pyschotic episode-only way I could explain. Im so glad I found this website because I definitely know its the zyrtec now. It is going in the garbage and I will call her doctor tomorrow and explain and see what else we can try. I just feel bad it took me so long to realize what was causing these episodes. | F | 34 | 1 years 2.5 ml 1X day | 5/18/2010 | 2 | allergies | I was so tired & exhausted all the time. It only helped some of my eye symptoms, it didn't really help my nasal symptoms. | I took a generic version. | F | 44 | 20 days 10mg 1X day | 5/17/2010 | 1 | seasonal allergy | Exhaustion and severe anger. | Additional warnings are needed for this drug. Use caution if operating an auto or machinery! | M | 48 | 4 days 1X day | 5/16/2010 | 1 | allergy symptoms | It made me beyond exhausted, and it did the same thing to my boyfriend. For about an entire day, all I wanted to do was sleep. However, I felt tired no matter how much I slept; sleep didn't make me feel rested. While awake, I felt anxious and my ability to concentrate was squashed. Meanwhile, my allergy symptoms were still pretty bad! The medicine only helped a little bit. I'm never taking a medicine with cetirizine hydrochloride again. It felt as if I hadn't slept for days, and couldn't get any relief. | I took Target's generic version, but it's the same as Zyrtec and even says to compare the two on the box. | F | 25 | 1 days 1X day | 5/16/2010 | 5 | seasonal allergies | none | No side effects, seems to work well. Zyrtec D is also good for those times when your allergies combine with a cold and you get a higher level of congestion. | F | 38 | 10 mg 1X day | 5/14/2010 | 4 | year round allergies | I have not experienced any side effects at all. Also, my six year old started taking this product a few months ago - and she has not experienced any side effects either. I am with the person who posted above in saying that the only people who seem to leave ratings are those with freakishly bizarre side effects. This product has worked well for us (and several friends of ours) for years and nobody I have talked to in person has experienced and side effects from it. :) | F | 41 | 4 years 10mg 1X day | 5/14/2010 | 2 | seasonal allergies | Restless less syndrome, rapid heartbeat, a sensation of my entire body vibrating, occasional difficulty sleeping, anxiety, tired feeling during the day. I take the tablet at night, just before bed. | It did work on the allergies. I had constant post nasal drip from mold and pollen allergies. The drip caused coughing and other typical allergy symptoms. The generic Zyrtec did clear this up quite a bit, not completely. But the side effects are too much to put up with, so I'm quitting the Zyrtec. I'd rather have allergies. | F | 59 | 90 days 10 mg 1X day | 5/13/2010 | 1 | Asthma | Massive appetite increase and gained 14 pounds. Sleepy all the time. | I couldn't understand why I was gaining weight all of a sudden and started thinking about what was different and realized that my doctor had added the Zyrtec. I stopped taking it and within 4 days I've lost 10 pounds. | F | 43 | 30 days 10mg 1X day | 5/13/2010 | 1 | Seasonal Allergies | Withdrawl, Abdominal Cramping, Foggy, *INTENSE* scary dreams | Always suffered from IBS but had been without a flare for almost a year then suddenly was hit with extreme cramping etc. Traced it back to this med so I stopped taking it. If I go without it I get itchy (ears, face, scalp, hands etc)and get a MASSIVE headache complete with nausea. At first I thought it was just a normal migraine but it didn't follow the right pattern and lasted for days. Horrible medication and there needs to at least be warnings of these side effects on the package. | F | 25 | 3 weeks 5mg 1X day | 5/12/2010 | 1 | All year allergy and astma | Non expect a bit drowsy | After taking zyrtec over 15 years (first 5 years seasonal afterwards all year long) it doesn't seem to help anymore. It used to work really good. But now still sniffing and sneezing all day long. But if I don't take it, (I tried to quit zyrtec) I'll be itchy all over and can't sleep. Can't go walking with the dogs 'cause my legs start to itch unbearably. However reading all these comments I will quit this evil Zyrtec.... | F | 30 | 15 years 10 mg 1X day | 5/12/2010 | 4 | seasonal allergies | No side effects whatsoever. I really want to try and put some people's minds at rest because it seems the only people who ever leave ratings are people who have had freakishly negative experiences with a particular drug and this may well deter others from trying a drug which might actually help them. Zyrtec gave me ZERO side effects. | F | 46 | 1X day | 5/11/2010 | 1 | Allergies | My daughter just started taking Zyrtec. Today the school called and said she was having a nervous break down. She is not the same kid. She is depressed, has anxiety, and talking about things a child her age should not even remember. I feel horrible for giving her this drug. She keeps saying "mommy I'm sad inside." | I called the doctor and he said to take her off of it immediately. Why do they prescribe it if there is this many problems???? | F | 5 | 13 days 5mg 1X day | 5/11/2010 | 1 | Allergies | Sleepy but I couldn't stay asleep for very long. Once I woke up I felt really weird. I felt like I was gonna have a panic attack or cry. A few hours latter I was sweating a lot and I became very cold. I also felt disoriented. Later that night I became very sick and thought I might even have to go to the hospital. It's two days latter and I'm still under the weather just not as sick. If I had taken any more whose to say I wouldn't have been dead. | I only took one I didn't need another one to increase the negative side effects. I had to go to work the day I took it for the first time only to find out several people had similar side effects. Also only to find out they were still taking it but said they took it at night. This is not candy if you are experiencing these type of side effects don't play Russian roulette stop taking it. I would never recommend taking this pill there are other pills on the market or you could get allergy shots. | F | 34 | 1 days 10 mg 1X day | 5/9/2010 | 1 | allergies | I became so angry over almost nothing at all. Co-workers and family noticed behavior. Would fly off handle for literally small issues. This is the second time I tried this with the same negative effects. | F | 58 | 2 weeks 10 mgs 1X day | 5/8/2010 | 1 | Seasonal allergies | Extreme fatigue, restlessness, general anxiety, depression | Ironic that the latest Zyrtec commercials show allergy sufferers getting ready to go golfing and bicycling after taking the drug since just one dose left me beyond exhausted within an hour. i cannot over-emphasize how tired Zyrtec makes me feel; I knew something was wrong because I never sleep during the day but I felt myself drifting off while driving, reading, watching TV and working. I could tell that if I actually let myself fall asleep, it would be the kind of deep sleep that goes on for hours but leaves you feeling groggy and disoriented upon waking. I don't know too many people who can take 12 hours out of their day to sleep! Luckily I bought the box with five pills because I will never take this drug again. I would rather sneeze 100 times per day than ever feel this low again. | F | 30 | 5 days 10 mg 1X day | 5/8/2010 | 2 | seasonal allergies | extreme exhaustion, headaches, body aches, flu like symptoms. Urinary tract infection | This medication worked great for me for the first 5 weeks. Weeks 5-8 were absolutely horrific. I thought had a horrible case of the flu. My body hurt so badly I could barely lift my arms. I could barely work all day (sitting at a desk) and have to come home and sleep for 2-3 hours just to make it to 10pm. The light bulb went came on for me when I read that a side effect is the urinary tract infection. I had an infection 3 weeks ago and had not ever had one prior in my life (39 yrs). It was such a gradual change for me that I had no idea that it was the zyrtec making me feel this way, just thought it was the allergies... 2 days off and I feel amazing again... allergies and all... I'd rather deal with allergies than feeling that way ever again. | F | 39 | 2 months 1X day | 5/7/2010 |
