| 1 | seasonal allergies | The allergy symptoms are gone, but I'll stop taking this medication because of the negative side effects. I've had headaches, dry mouth, cold sweats, nausea and extreme sleepiness. Didn't feel it would be safe to get behind the wheel of a car, as I could barely keep my eyes open even after a good night's sleep. I take the Zyrtec at bedtime. | I'll either suffer through the allergy season or seek a prescription for Flonase again. | F | 55 | 6 days | 8/8/2008 | 1 | Ragweed pollen allergies | It feels like my brain is still asleep the next day. Tiredness, Lethargy, Brain fog, Sadness | The morning after I took prescription Zyrtec I woke up extremely congested and irritated as if I hadn't taken an allergy pill. Apart from the fact that I still had all the allergy symptoms I had the added bonus of all the negative side effects of this medicine. I sat on my bed all day waiting for the side effects to wear off. I had a date later that evening and worried that I will appear depressed or miserable. This was so frustrating. I won't take this medication again 😔 | F | 55 | 1 days 20 mg | 10/12/2015 | 1 | Post nasal drip | I felt paralyzed, drugged and so lethargic I could not function. I also had a terrible metallic taste in my mouth. | Scary stuff and I probably should not have driven the car! | F | 55 | 2 days 10 mg | 8/10/2016 | 5 | alergic to mold, bad on rainy days | Tired most of the day. But at least, the pain was gone. | F | 56 | 2 years | 10/29/2007 | 5 | allergies | None | I LOVE THIS STUFF! I have had zero side effects. It is wonderful for allergies(I live where allergies are very common) and even helps me not get a headache after consuming wine(which is a blessing). I take the generic thru Kaiser. Best drug ever. I take as needed, have been taking it for years, as does my husband, daughter, mother, all my other kids, and I tell people all the time about it. A great antihistamine. | F | 56 | 3 years 10 mg 1X day | 8/15/2011 | 4 | sneezing, itchy eyes, runny nose | headache, low energy, persistant cough | great for running nose and sneezing , but i am not sure it was worth it, due to the side effects, | M | 56 | 10 days | 5/11/2008 | 4 | Allergies | Slightly drowsy during the day but not nearly as bad as benadryl. | Performs as advertised but still makes you a little sluggish during the day. My advise is to always take it at night before bed. | M | 56 | 3 months 10mg 1X day | 8/19/2017 | 4 | Allergies/Asthma | Dry mouth in the morning. Zaps your energy levels a little bit. | Really helps with my asthma, especially in the morning. Works much better than claritin and allegra. Make sure to take it at night before bed otherwise you'll be dragging your feet all day. | M | 56 | 3 months 10mg 1X day | 10/4/2017 | 4 | seasonal allergies | As I read in another entry, I slept better than I have in years and my mood was much better than usual, feeling positive and confident, more so than usual. I also had vivid dreams which are unusual. | Due to worries about side effects I quit taking Zytec two days ago and am already back to not sleeping well. Oh, well. | F | 56 | 6 weeks | 6/8/2008 | 3 | seasonal allergies | Extremely dry skin all over especially on face ..flaky eyebrows and dry Cracks around my eyes and mouth....even dry.using vasceline on my face. Severe rash and itching on hands and wrists. My skin and body dry everywhere. | F | 56 | 4 months 10mg | 6/4/2015 | 3 | Indoor and outdoor allergies | Weight gain is probably the worst side effect of this drug. I balloon 10-15 pounds when on it for extended time. Other side effect is loss of sexual interest. Once I go off of it, within 24 hours I'm fine again. | This is the only drug that works for me. I take it at night and it does cause a deep sleep like a sleeping pill. But takes a while to get going in the morning. I"m back on it now for about 6 weeks because of the Fall allergies. I plan to get off today and take a break. I'm tired of the weight issue and will seek someting to try at night and get by. Also I noticed if you use it regularly it does lose some of its working strength. | M | 56 | 12 years | 11/15/2008 | 3 | sinus headaches | Graphic and disturbing dreams; some sluggishness | I started taking Zyrtec at night because I was waking up with sinus headaches every morning. It worked well for that, so I have rated it 3. It completely knocks me out, especially if I have had any alcohol at all, even a single glass of wine at dinner, and it takes me a while to get moving in the morning. I have constant, vivid, disturbing dreams almost every night. My husband told me I woke up after an hour last night saying, "Scared, scared" over and over. I have no memory of that. I am going to stop taking this, or at least cut the dosage in half. If you do take it, follow the label warnings - no alcohol. | F | 56 | 30 days 10mg 1X day | 2/20/2010 | 3 | bad cat allergy | Took 24 hrs for my legs to get rid of the edema. I have not taken zyrtec to two days and so far no problems with the cat. I'm trying to see when the cat allegy kicks in so I know about how long I have between when I need to start/stop. | F | 56 | 10 1X day | 6/16/2010 Patient History | 2 | hives | Dry mouth, sleepy, lithargic | Zyrtec was prescribed for hives, but on a scale from 1 to 10, it was a 2. | F | 56 | 60 days | 8/16/2004 | 1 | To clear nasal passages, hay fever | Itching all over body, esp arms and legs and face. Lethargy and slight loss of mental focus. Very uncomfortable. Will never use it again. | M | 56 | 4 days | 10/8/2008 | 1 | CHRONIC COUGH FROM POST NASAL DRIP | THIS STUFF IS AWFUL! THE FIRST PILL KEPT ME UP ALL NIGHT. THE THIRD PILL GAVE ME HORRIBLE ITCHY WELTS ON MY FACE & CHEST. MY HEAD FEELS WEIRD. ITCHY ALL OVER & ACHEY--I'VE NEVER FELT LIKE THIS IN MY LIFE. I'D RATHER HAVE THE FLU ANYDAY. | DO NOT TAKE THIS DRUG! I GOOGLED THE SIDE EFFECTS AFTER I GOT THE ITCHING & WELTS. WISH I'D KNOWN SOONER. I'VE NEVER FELT SO ROTTEN IN MY LIFE. HOPE SOMEBODY OUT THERE PUTS THE COMPANY OUT OF BUSINESS. | M | 56 | 2 days | 3/27/2008 | 1 | seasonal allergies | Bought this instead of Claritin which I have taken for years with noe problem. Within hours- stomach ache, bloating, no appetite and my mood changed. Symptoms did not go away. Took Zyrtec for three days and finally connected my gastroparesis with this OTC med. Vivid dreams started first night. Will never take this again. | F | 56 | 3 days 10 MG 1X day | 6/15/2010 | 1 | allergies | Always felt exhausted. Generally, everything seemed overwhelming. | Decided to stop taking zyrtec this week because I was tired of feeling exhausted all of the time. Could not wake up in the morning. After 4 days without zyrtec, I felt much better, but now I am experiencing itching all over. I guess zyrtec prevented this itching, but I am not sure it was worth it. Looking for another solution. | F | 56 | 3 years 1X day | 10/17/2010 | 1 | seasonal allergies | I have taken Zyrtec probably for about 9 yrs. I took other allergy medicines before that. I have had seasonal allergies for about 35 yrs. As I get older I have found that I am tired all the time and have no energy to exercise. I have tried going off Zyrtec before during the winter months but always have the itching that gets worse with each day I'm without Zyrtec so I usually start it again. But after reading all these testimonials, I am going off it for good. It's been 4 days since I took Zyrtec and I am feeling flu symptoms. I just feel really weird and have a sore throat. I don't know if this is from not having the Zyrtec or if I really do have flu symptoms (I haven't felt right for 2-3 days) and its not getting any better. Has anyone had these symptoms when going off Zyrtec? The itching hasn't started yet. | Had I know that Zyrtec was addictive - I would not have started it! My doctor never told me! | F | 56 | 9 years 40 mg 1X day | 11/18/2010 | 1 | year round allergies | after not taking zyrtec for 3 days I begin to itch severly all over the trunk of my body, now it is down to 2 days. Even when I have no allergy symptoms I have to take it to keep from itching to death. | It helped for the first several years then I found I could not stop taking it even when I didn't need to. How can I get off this medicine? I told my doctor and he said well you must be allergic to something. | F | 56 | 5 years 30 mg 1X day | 9/14/2010 |
