 3  Allergies Even though the package says non-drowsy it still makes me super tired, I take it at night and it helps me sleep better but when I wake up I'm still tired! I feel like no one wants to be around me and I get random bursts of dizziness. It makes my knees ache more than they usually do too. It works great for allergies but the side effects are horrible.

 1  Allergies Anxiety, depression, rage, dark thoughts, insecurity I which I could give a negative rating for ZYRTEC. Zyrtec turned my daughter into a different child. Over the past three months she has changed from a typical 11 year old (with occasional drama but always good natured, kind and reasonable) into a girl that has intense irrational meltdowns several times a day. I am very sad to say that we initial brushed her behavior off as typical preteen drama but the intensity of her outburst made me believe that something else was going on with her. I finally made the connection this morning and began researching the side effects. I called my child's doctor and sadly they have never heard of any side effects like this from Zyrtec - wow- so scary! I encourage anyone who has had side-effects to log them here. I usually do not do this, but I am so scared for the kids that are taking this drug. If parents do not make the link between ZYRTEC and behavior these children could easily and unnecessarily get diagnosed with a mental health condition. F 11 3 months

 5  sinusitis from allergies relaxes me when I take it at night Zyrtec is the only allergy medicine I have taken that actually works and does not give me bad side effects. When I take it daily it keeps my sinuses clear, and I no longer have itchy watery eyes and ears. Without Zyrtec, I cannot breathe through my nose. This medicine has greatly improved my enjoyment of life and I am so glad it does not give me any bad side effects! F 52 6 years

 3  Seasonal allergies Fatigue, lethargy, increased hunger, weight gain, feelings of nausea several hours after taking it, irregular sleep. While Zyrtec does a great job controlling my seasonal allergies it comes at a high price. I find it hard to believe that only 2% of Zyrtec users are affected by weight gain. Seems like a tons of complaints about it. I've always been a 3 meals a day person but since I started taking this I'm hungry all the time and my stomach is growling between meals. I take it around 8:00 at night so that I can sleep off the drowsy side affects, but they still linger through the next day. I've also encountered some waves of nausea 7-8 hours after taking it (and yes I take it with food). Adding Zyrtec is the only change I've made to my routine so I can't attribute these problems to anything else. F 44 3 weeks

 1  seasonal allergies Facial tic (eye squinting/blinking) My 9-year old son developed a facial tic immediately after starting zyrtec. One eye was squinting/blinking non-stop, every few seconds all day. At first, we thought it was a coincidence...but it started again when we tried to reintroduce it. His pediatrician said it's not uncommon. M 9 4 days

 1  Hayfever, season allergies I have never taken allergy medicine but this season my allergies seemed worse. I do not have any nasal congestion, but terrible itchy eyes and nose. I took this for a few days and noticed that I was irritable, very drowsy, lethargic and it did not change my hayfever symptoms at all. In fact my nose burned and my eyes itched worse than ever. I am extremely sensitive to medication of any kind. One benedryl will knock me out for a day. Everyone is different. My husband takes zyrtec with no side effects. My advice if you are someone who struggles with anxiety or tends to be very sensitive to medication, do not take this. I have been off of it for a few days and feel back to myself again. I am thankful that I realized what was causing these changes in me before I took it long enough to experience worse side effects. I would not recommend this to anyone who is similar to me in sensitivity to medicine. F 31 1 months

 1  Allergies With Zyrtec, you fall into a deep sleep that is extremely difficult to wake from, so much so that I actually almost wet the bed! Also, I have been in a bit of a mental fog for most of the time. When I am not in a fog, I am getting irritated, easily, for no real reason.... F 3 days

 1  seasonal allergies This is actually a rating for my 2 year old daughter's experience. Her doctor recommend OTC childrens zyrtec for slight seasonal allergies. We thought she had suddenly and aggressively started with the terrible two's. She was having constant meltdowns over the tiniest things, hitting constantly, and just being downright malicious. Finally I happened to mention to my sister that my child was on Zyrtec and she told me to take her off it. Turns out my sister gets the same side effects on this drug and since then I have met many people who say that they have had the same experience. My daughter reverted back to her happy-go-lucky, joy to be around self in a matter of a few days. She will NEVER take this medication again. I have started to notice some of these side affects in myself when i started to take Zyrtec this year. I am switching to claritin or allegra. F 2 3 weeks

 1  seasonal allergies dry mouth, sore throat, EXTREME irritability I have suffered my whole life with seasonal allergies. I have tried many otc allergy medicines. Most do nothing but make me sleepy. Upon trying this medicine, I thought I finally found the one! I have had no allergy problems at all. Unfortunately, it did make me extremely thirsty and give me a sore throat. Those are side effects I could deal with. However, I noticed that I was not my normal cheerful self. I am a very happy person, but today, I was so negative about everything. The only change was the medicine. Everything made me so mad, even the littlest things. I teach elementary school and feel so bad about the way I treated my students today. I snapped at them for every little thing, even things they could not control. I will NEVER take this medicine again. I would rather go through months of being drowsy from Benadryl than dealing with these side effects. F 38 1 days
