The Zyrtec Itch is Unbearable | Where’s the FDA?

We have reported "the Zyrtec itch" to the FDA with disappointing results. Hundreds of people have reported problems with itching when they stop Zyrtec suddenly. The FDA doesn't respond to our concerns

We first heard about the Zyrtec itch over eight years ago. A reader reported horrible itching within three days of stopping Zyrtec (cetirizine is the generic name for this antihistamine). He reported that the Zyrtec itch was so bad he was preparing to go to the hospital. When he restarted Zyrtec, the itching magically disappeared. Here is a link to that original story along with hundreds of comments from other visitors to this web site.

We notified the FDA. We got no response. Just a few weeks ago we contacted one of the highest executives at the agency to  again report that stopping cetirizine suddenly could trigger the Zyrtec itch. We were told we would be contacted by the person in charge of such matters. So far, we have heard nada from that person.

The Zyrtec Itch May Appear When the Drug Is Stopped Suddenly:

Q. I have been taking Zyrtec for several years on a daily basis. Any time I go more than three days without it, I start to itch like crazy!

I found several articles on your website with people complaining of the same thing. My question is: how do you stop taking it? What is the best way to manage the withdrawal from it?

A. Hundreds of readers have written to us about this problem. Stopping either cetirizine (Zyrtec) or levocetirizine (Xyzal) suddenly may trigger unbearable itching that could last for some weeks. If you can stand the itching, it should ease up eventually.

A medical report on this phenomenon recommends gradual dose reduction or a short course of corticosteroids such as prednisolone to ease the itching during withdrawal (Drug Safety Case Reports, Dec. 2016).

Ideally, people would be alerted to this potential problem before they started such antihistamines, so the itching wouldn’t come as a surprise.

Other Stories from Readers:

We are fairly certain that many people can take Zyrtec and Xyzal without problems. These individuals probably experience no withdrawal symptoms upon stopping the drugs suddenly. The trouble is that we have not found large, well-controlled studies to confirm our hypothesis. We would like to know if this is a rare occurrence or fairly common. As far as we can tell, the FDA has not required the manufacturers to carry out such tests.

Here are just a few more stories from readers:

Nikki in Tennessee reports the Zyrtec itch on stopping the drug:

“I am itching to death! I tried to come off this medication a few months ago with no luck. I had severe withdrawal from stopping the medicine cold turkey.

“I went back on the drug until till last Sunday. I stopped, but slowly. I’m having new symptoms daily. I started taking Zyrtec again but, I’m beginning to itch all over. My skin is crawling. I’m burning up from the inside. I have a red rash all over my chest. It feels like bugs are crawling all over me. I have red itchy eyes, sneezing, watery eyes. You name it, I have it right now! I refuse to take it ever again, even if I itch myself to death!”

J.D.B. in New Zealand reported an itch with a different brand of cetirizine:

“I have been on my hay fever medicine for a few years now but they recently ran out. I was too busy to get more.

“Lo and behold the itching started. It’s only been 3.5 days and I’m ready to rip my skin off! Dya think it could be the med? I take Zetop.”

Upon doing some checking we discovered that Zetop is a form of cetirizine.

Josh in Kansas City, MO, adds his perspective:

“I have tried to stop taking cetirizine for over a year. I went to my allergist and asked if cetirizine could be the issue. He said it has to be something else. He told me to take cetirizine every night and Claritin every morning until my hives and itching were gone for 3 months. Then he said I could try again to stop taking it.

“What dumb advice. I did this for 2 months and then tried to stop taking it again. After one day I started getting hives again.

“This is not something I had prior to taking cetirizine. I had seasonal allergies. If I had known I could become dependent on this drug and have horrible hives all over my body as well as itching on the bottoms of my feet, I would never had taken a single pill.

“I have been off of it for eight days. During that time I have only been able to get relief with Benadryl. I am also taking a Quercetin blend and don’t know if they are helping at all. I hope this gets out of my system soon. I have never had itching this bad on the bottoms of my feet.”

I started itching when I went off of Zyrtec. My solution was to take Claritin for a month. My allergies were not controlled as well as with the Zyrtec but the Claritin did control the itching. After a month, the itching had stopped.

I’ve been taking Zyrtec for about six months. I had to stop five days ago before allergy testing. Two days after I stopped I started itching uncontrollably! I’m absolutely miserable. I’ve scratched the palm of my hands raw, bruised the upper part of both arms from scratching, my face, scalp…..it’s generalized…..all over! It’s almost as if allergists and medical staff are forbidden to talk about it! I tried to talk to the nurse about it before my allergy test, and she gave me a validation nod, but wouldn’t say anything! When I started scratching everywhere, I thought it was all in my head. I’m grateful to have found all these other people who have experienced this withdrawal symptom. I can’t believe the FDA is not taking this seriously. It’s almost debilitating and also alarming when it hits you.

Hi – I took Zyrtec D everyday for one year and determined that it was causing me chronic constipation. Upon my own research, antihistamines are one of the top 8 medications that can cause constipation. I stopped cold turkey not knowing that after two days of being off of it I started itching like crazy! The same as everyone else here describes. Unbearable insane itching! I refused to go back on it and got some relief from Benadryl and Claritin for about a week. I stopped both and for three weeks I was absolutely fine. This morning I woke up and the insane itching started again! Crazy! The tree pollen count is high and I am not sure if that is what triggered it but I am back to feeling like I did the first week. I thought I had it beat! Crazy! Took a Claritin and it does dissipate some of the itching but not completely.

Is there a class action lawsuit on this? I am ready. Been struggling with this for years. An inside-out itching sensation which causes so much stress.

I got off zyrtec because it gave me unbearable heart burn. The heart burn gradually stopped when I stopped Zyrtec.

8 years ago I went off Zyrtec. Horrible itching, painful sores and spots coming up at my most sensitive areas – anywhere fabric touched my body. I’ve had 8 years of itching to figure this out. I ended up going back on Benadryl. My doctor told me not to bother trying to figure out why I had this horrible affliction. I read the comments here periodically. I think there is a connection between Zyrtec use and those who had a prior sensitivity to Sulfa drugs.

Here is what I’ve done:

I quit eating wheat and soy. I found my health got somewhat better, but I still itched.
I found that certain alcohols made me turn bright red.
Potatoes and legumes made me itch.
Dairy made me itch.
Everything made me itch.

A week ago, I made an organic turkey for Thanksgiving. It is just me and my husband at home now, and my daughter and her boyfriend came for Thanksgiving dinner, so we had lots of leftovers. I ate nothing but organic turkey all week and for the first time in 8 years I have no hives!

If you do one thing, eat organic meat. It really makes a difference!

I ate potatoes and got no hives. I drank wine and did not turn red!

Last night I did the reverse test – I ate some non-organic meat. I started itching. Mildly, but it seems to have built up in my system. 8 years of AGONY, and I was poisoning myself the whole time.

EAT ORGANIC MEAT!

And fon’t forget about organic dairy as well.

I am ecstatic right now, feel healthy and have tons of energy. I was on so much benedryl that I became dizzy when the hives started going away. I tapered off and am down to two pills a day, and will be completely free in another day or two.

Pay the extra money and eat ORGANIC. Don’t wait 8 years like I did.

I discovered the dreaded itch when I had to get off of Zyrtec for 3 days for allergy testing because it was no longer helping. The itching is so bad that I have bruises from scratching! Stupid doctor told me just to take more. Benadryl helps, but it has to be capsule or liquigel. Tablets take too long to get into my system. I’ve also had to take sleeping meds to help. Today it was triggered by stress, but good luck controlling that. Been off for couple weeks and refuse to go back on that stupid drug!

I took Zyrtec for 2 years on the advice of my allergist. I stopped two and a half years ago. I started itching all over the abdomen area and on my forehead and hairline. It’s still itching to this day. For relief, I started using frankincense essential oil. It stops the itching for quite a few hours. I usually rub the oil on morning and night. It was just by chance that I started using frankincense. I became interested in the essential oils. After reading up on some of the oils, I saw that frankincense was good for my skin. I had been having a problem with 2 sores flaring up in my nose, which I think is caused by something internal in my nose. Well I rubbed the oil in my nostril, and honest to goodness the pain and sores disappeared in a few hours. I tried it again on a sore, and it did the same thing (cleared up). Thank you, frankincense!

I am 22 days off of Zyrtec cold turkey and still have minor itching. Now usually palms or feet. To get me through the unbearable withdrawal I mixed 10 to 12 drops of tea tree oil in 2 tablespoons of coconut oil and slathered it all over my body. It instantly soothes the skin, but sometimes insane itching would return in a few minutes. Diet has a lot to do with intensifying the itching. Avoid high histamine foods such as beans, pickles, green olives, kombucha, buttermilk, cheese, dairy, tomatoes, mushrooms, canned salmon or tuna, bacon, sausage (cured meat) and my favorite …. hot sauce!

Also avoid artificial dyes. Those are some of the foods I was eating everyday. Google high histamine foods and avoid them. Changing my diet and avoiding vinegar based foods decreased the itch in one day. (Before figuring this out I had a can of tuna and itched for 2 days straight with major anxiety).

Each outbreak has become less severe. Also hydrocortisone cream helps defensive the itchy spot but doesn’t always stop it. I ditched the tapering idea because I felt putting it back into my system even a tiny bit was feeding the addiction. Good luck to everyone dealing with this, you will get through it!

Solution: Taper. I experienced this too and my solution was to start cutting the pills in half and taking just 5mg instead of 10mg. 5mg worked just as well for me, and when I ran out, I did not have the same awful itching. Unfortunately my allergies came back with a vengeance recently, so I’m back on it. Never the less…
