"Zyrtec works fine for our allergies, but it's hard to imagine a company that shows less concern for the environment with their packaging. Their Go Packs have a cover package and individual packaging for each pill. Little is biodegradable, and the waste is extreme. We'll start using other products that show more concern and care."

"The worst drug that I ever took. Took it only twice, I wished I had read all the reviews before I took it. Made me so tired, all my body hurts for the whole week, exhausted that I had to call off from work. Gave me so much anxiety. Worst drug on the market, please don’t take it. Just handle your allergies in a natural way. This one helps a little bit, but you have to pay the price with all side effects."

"Took Zyrtec for approximately 6 months for a skin reaction I developed from vitamins. Decided to stop taking. This is how I did it... I went from taking the 10 mg pill to 1/2 pill for 3 weeks. The 4th week, I took 1/2 pill of Claritin. I then went to 1/4 pill of Claritin for two weeks. I am now free of Zyrtec and all antihistamines with very minute itching. Consult your doctor, but this truly worked for me."

"I had been perplexed how I put on 12 pounds so fast within two months. I started thinking about what I have been doing differently. It was I started taking Zyrtec. I stopped taking it 5 days ago and have lost 4 pounds. My appetite is controlled and my energy level is starting to increase. I am having extensive itching on my back and head. I am never taking Zyrtec again. I will research homeopathic options. Beware!"

"Zyrtec made me so sleepy I could barely perform my job. Also felt sluggish and dangerous while driving. All I could think of all day was 'I need to go to sleep.'"

"After a week using it, all symptoms were gone. If I miss it 3 to 5 days, symptoms returned. No drowsiness is the best part."

"You are not itching from any kind of addiction. You are itching from the histamine in your system when you stop the allergy meds. Try natural D Hist and Xlear nasal spray instead."
