 1  Allergies Zyrtec induced severe short-term memory loss in me for several *months*. I was out of work for much of the time because of it. This is a very rare and isolated case, so you shouldn't have to worry about it, but be warned that it might cause temporary memory loss. M 29 1 days

 4  pet and seasonal allergies Increased hunger and weight gain - I asked the pharm and the dr. about this and they do not have any proof that it is related to Zyrtec but I have never had a weight problem and now I am 7 stubborn pounds overweight in just 3 months My allgergic reactions are pretty severe but very sporadic. I have been pleased to be rid of them but I think I will deal with them as they come and take something else. F 44 3 months

 3  Hayfever Only slightly tired or lethargic, well worth it for the releif from hayfever however it does seem to cause mild to serious depression and insecurity depending upon how much and how often you use it. I've used zyrtec on and off for 2 years and i recommend that you use it to relieve short-term allergies, it works brilliantly, however I would hesitate before taking it for longer periods of time such as an entire week as this is when the side-effects seem to develop.

 2  allergies itching, low sex drive, mood changes I no longer have pets, so I recently tried to stop taking zyrtec and about 2 days later experienced horrible itching all over. Only recently has someone mentioned that problems with low sex drive could be related to this medecine--glad to know others have experienced similar problems. F 22 4 years

 1  allergies, sinus headaches Extreme fatigue. I took it at night in hopes that I would feel better in the morning and I was wiped out all morning. I even tried splitting the 10mg tablet in 1/2 and seeing if that would help but no luck. I have switched to Flonase and OTC NasalCrom and I have been very happy withe the results. I would avoid Claritin, it gave me scary irregular heartbeats. F 32 5 days

 4  nasal allergies dry mouth Don't take if you've been drinking I threw up one time. This is a very strong antihistimine. Works great on keeping my allergies at bay. I have severe allergies so no medicine seems to help once pollen season hits especially oak pollen. Seems to work better on cat dander than dust or pollen maybe that is a lesser allergy for me. Overall, it is the best antihistimine I've tried. My allergies were terrible when I took Allegra. F 35 5 years

 1  counteract new allergy to Voltarin Zyrtec was prescribed for it's antihistamine effects to counteract the effects of the drug Voltarin. (effects of Volatrin was that I was wheezing 24/7 and so bad at night I was unable to sleep) Doc said you are now alergic to all NSAIDS. Well one of the side effects of Zyrtec is it causes DIFFICULTY BREATHING. Now, not only am I wheezing but am even shorter of breath and coughing! They really should tell you about ALL the side effects before you start taking it. The only thing they said to me at the pharmacy after I paid for it, was: Got any questions?? Seems like I am allergic to everything, and this was the first time I saw a doc in 25 years! Should have kept listening to my body telling me to stay away from the medical profession... F 52 4 days

 1  allergies My child went immediately from a happy, sweet child to a wild raging monster. She has never been one to throw temper tantrums and she was nearly unrecognizable as the same child. She seemed distraught and unable to control her emotions. I would not recommend this for anyone who has experienced sensitivity to antihistamines. F 3 4 days

 1  sinusitis My 8-year-old daughter was given zyrtec for 2 weeks to treat sinusitis first and then sinus infection. She became moody, started displaying extreme anger and irritability. It culminated into a terrible, violent temper tantrum on day 12, in which she was screaming, scratching her face and kicking everything around her. This is totally uncharacteristic for her. As a toddler she threw a few tantrums, but never as violent as this. It didn't occur to me it was the medication until then. She's now off of it for 3 days. Lingering effects on her mood continue but to a lesser degree. I had been reading on this site about similar effects on adults and children who took Claritin and other loratadine brands. She had taken Claritin for a week two months back, for similar sinus-related complains. After the violent tantrum, I checked for Zyrtec effects, and was surprised to find the same. Our pediatrician never warned us of such side effects. All my research on the web didn't bring up anything like that, until I FOUND THIS SITE. It's the only place where this information is available. THANKS. F 9 12 days

 1  Chronic Allergies Severe moodiness, mood swings, easily aggitated, groggy, cloudy headed, extremely tired. I am 5 months pregnant and my allergies worsened so I was put on Zyrtec. Talk about mood swings.. and hormones surges. I cannot believe that my doctor did not warn me about this. After 9 days and two horrible fights with my husband I took myself off of it. I would rather suffer through the allergies than experience these side effects. F 35 9 days
