Zyrtec and sinus infection

I have been taking Zyrtec for about three months. Doctor suggested I take it for a month after bad sinus infection. I was still all choked up after a month so I kept taking it.... I also take an antidepressant, Citalopram, that I've been taking for years. I have wondered since taking Zyrtec if there are any long-term side effects. After reading the postings above I found several symptoms I've been experiencing lately that others contribute to Zyrtec. I stopped taking Zyrtec tonight and will see if anything changes. I definitely have little energy and wake up with excruciating back pain, but I had a fair amount of back pain before I took Zyrtec. I have pain in my upper left arm that is getting worse each day. Heartburn at night. I had very weird dreams lately - I was on "drugs" that made me completely loopy, dizzy and out of it. I woke up dizzy and realized the dream was partly reality.
I have had some headaches and racing heart. I just thought I was getting old and falling apart!! We'll see...
Will keep you posted.

I have allergies to dust mites, and started taking Zyrtec to help get over a sinus infection. It worked great at first. Then I started to feel not myself, and my thoughts were out of control. I have depression, and it magnified it. I stopped taking it, and started taking Claritin, which made me feel speedy and gave me heart palpitations.

This is my first time taking Zyrtec D. It was recommended by my local pharmacist. I have had a terrible sinus infection which has lead to a massive ear infection. The ear infection is getting worse . every time I blew my nose, I felt like my ears were going to pop right off my head. Anyhow, the only thing that has made me feel better is Zyrtec D however the side effects I am experiencing from this are far more worse and are not worth it. I am very anxious to the point where my muscles ache. I also have excessive crying spells and I also have been super angry all day. I have taken 2 pills in the past 24 hours. My ears are still clogged but my nose is clear. I am also experiencing shortness of breath and increased heart rate. I also can not sleep and I keep waking up with horrible dreams. I have been searching the internet now to figure out how to get this drug out of my system. Although I can now breath, the side effects are not worth it. I would rather have a stuffed nose then ever take this again.
