The FDA Warns of New Zyrtec and Xyzal Side Effect. What Is Pruritus?
According to the FDA, 62.7 million over-the-counter packages of Zyrtec (cetirizine) and Xyzal (levocetirizine) were purchased in 2022. Since allergies are getting worse -- partly because of climate change creating longer, more intense pollen seasons -- these numbers have likely climbed in the last three years as more people purchase the antihistamines to cope with allergy symptoms like a stuffy nose, watery, red, itchy eyes and hives. For the millions of people who take these drugs, it's important to know that the FDA recently published a warning about a newly discovered side effect that may occur after taking both Zyrtec and Xyzal. If you stop taking Zyrtec or Xyzal after long-term use, you might experience "rare but severe" itching. Also called pruritus, this itching was experienced by patients who had been taking these allergy medicines every day for several months or years and then stopped. What is the FDA going to do? The FDA decided to issue this warning after identifying 209 cases worldwide -- 180 cases for cetirizine, 27 for levocetirizine and two for both -- of this particular side effect reported between April 2017 and July 2023. In the US, 197 cases were reported. However, there may be more, because these are only those that were reported to the FDA. Interestingly, even though most patients who experienced this severe itching had been taking these antihistamines for more than three months, some had this reaction after less than one month of use. Because of these findings, the FDA will now include a warning on the prescribing information for prescription cetirizine and levocetirizine. The administration is also asking that manufacturers add this warning to drug facts labels for OTC versions. When to contact your doctor If you stop taking OTC cetirizine or levocetirizine and develop severe itching within a few days after you've been using the medicine daily for several months to years, you should contact your doctor. If you plan to take these medicines for a prolonged period of time, you should also discuss the pros and cons with your doctor before starting. How to treat this new Zyrtec and Xyzal side effect According to the FDA, no effective treatments for pruritus have been found. However, most patients discovered that their symptoms resolved after they restarted cetirizine or levocetirizine or after they tapered off the antihistamine after restarting it. Before you try this, consult your doctor to make sure that's the best course of action if you think you're dealing with this Zyrtec or Xyzal complication. According to the FDA, the most common, already-known side effects of cetirizine and levocetirizine are fatigue, drowsiness, sore throat, cough, dry mouth, nosebleed, fever, diarrhea and vomiting. What is pruritus? Plus, additional symptoms to know The Cleveland Clinic reports that pruritus is the medical term for "itchiness." It can be painful or irritating and spread to multiple areas of the body. Other symptoms of pruritus can include a rash, blisters, large bumps, small pimple-like bumps and skin discoloration. Scratching the skin can cause additional symptoms, such as skin breaks and bleeds, scratch marks, dry or cracked skin, broken skin that leaks a yellow to white fluid (infection), localized pain where the skin itches and a thick, leathery patch. That is why it's important to do what you can to manage your itching under the care of a doctor. Dry skin, pregnancy, contact with an allergen and a reaction medication are common causes of pruritus. If it occurs for over six weeks, it can be considered chronic.

The New Zyrtec and Xyzal Side Effect: How to Treat It and When to Contact Your Doctor
Allergies are, in fact, getting worse. That would explain why common allergy medications like Zyrtec (also called cetirizine) and Xyzal (levocetirizine) fly off drugstore shelves every year to treat allergy symptoms like a runny nose, itchy eyes and even hives. However, if you take these drugs, there is something you should know: The FDA recently published a warning about a newly discovered side effect that may occur with both Zyrtec and Xyzal. If you stop taking Zyrtec or Xyzal after long-term use, you may experience rare but severe itching. Also called pruritus, this itching was experienced by patients who were taking these allergy medicines every day for several months or years. The FDA estimates that 62.7 million over-the-counter packages of cetirizine and levocetirizine were bought in 2022. In the same year, about 26.8 million cetirizine and levocetirizine prescriptions for OTC and prescription products were dispensed from US outpatient pharmacies. Considering that allergies are getting worse -- partly because of climate change creating longer, more intense pollen seasons -- it wouldn't be surprising if these numbers continue to climb.

Popular allergy medications linked to severe withdrawal symptoms, FDA warns
Two common allergy medications could cause a severe reaction in some people who stop using it. The U.S. Food and Drug Administration (FDA) issued an alert related to cetirizine (Zyrtec) or levocetirizine (Xyzal), warning that patients who stop taking it after long-term use may experience "rare but severe itching," a condition called pruritus. The itching was reported by people who used the medicines every day for months or years, and then stopped using them. In total, 209 cases were reported worldwide (197 in the U.S.) between April 25, 2017, and July 6, 2023. "This number includes only reports submitted to FDA, so there may be additional cases of which we are unaware," the agency stated in the release. "Reported cases were rare but sometimes serious, with patients experiencing widespread, severe itching that required medical intervention." Many reports described a "significant and persistent impact on quality of life and ability to function," the FDA noted. In most cases (90%), restarting the medicine resolved the severe itching. Some (38%) had success with gradually tapering off after restarting. The drugs are available in both prescription and over-the-counter versions. "I suspect this might be due to accelerated histamine release once the blocker is stopped." The FDA said it will update the medications' prescribing information to include a warning of the itching risk, and will also ask the manufacturers to add the information to the drug facts label for over-the-counter versions. Cetirizine and levocetirizine are antihistamines that are approved to treat seasonal allergies in adults and children 2 and up, according to the FDA. The drugs are also approved as a treatment for year-round allergies and chronic hives in patients 6 months and older. People who experience severe itching after the cessation of these medications should contact a healthcare professional, the FDA advised. "Individuals planning on long-term use of cetirizine or levocetirizine, especially for more than a few months, should discuss the benefits and risks with your healthcare professional, who can provide advice based on your personal needs," the agency stated. Other common side effects of cetirizine and levocetirizine include fatigue, drowsiness, cough, dry mouth, fever, sore throat, nosebleed, diarrhea and vomiting, per the FDA. Dr. Marc Siegel, clinical professor of medicine at NYU Langone Health and Fox News senior medical analyst, noted that these medications are "very effective" at alleviating allergy symptoms. "The FDA is noting that in extremely rare circumstances after long-term use, stopping them can lead to severe itching, which is alleviated after restarting them," he reiterated to Fox News Digital. "I suspect this might be due to accelerated histamine release once the blocker is stopped." A spokesperson from the Consumer Healthcare Products Association provided the below statement to Fox News Digital. "Consumer safety is the top priority for CHPA and our manufacturer members. The OTC industry supports FDA's ongoing commitment to notifying the public about safety signals, even when extremely rare, as in this case." "CHPA members will continue to comply with FDA guidelines, including any needed updates to Drug Facts labels, while also evaluating and monitoring the latest science and product profiles. Consumers who use these medicines daily for an extended period (months-years) should not stop taking their medication abruptly without first consulting with their healthcare provider." For more Health articles, visit Opella, the manufacturer of Xyzal, shared the below statement with Fox News Digital. "Xyzal has a strong track record of safety and efficacy backed by scientific research and user satisfaction. This is a rare reaction, and Opella stands by the safety of Xyzal when used as directed."

Millions take these allergy meds... now the FDA says they may WORSEN symptoms
An FDA warning has been issued over a new crippling side effect of allergy drugs taken by more than 60 million people worldwide. The FDA says it has received complaints from patients who suffered from severe itching after stopping the oral allergy medicines cetirizine and levocetirizine - sold under the brand names Zyrtec and Xyzal. These medicines are available in prescription and over-the-counter forms. The itching, also called pruritus, has been reported in patients who used these medicines daily, typically for at least a few months and often for years. Patients did not experience itching before starting the medicines. Pruritus in its most severe form can cause skin damage and open sores, with patients reporting distress and difficulty sleeping. Health officials said the cases were 'rare but sometimes serious, with patients experiencing widespread, severe itching that required medical intervention'. As a result, the government agency is revising the prescription cetirizine and levocetirizine prescribing information to include a new warning about this risk. Manufacturers will also be required to add a warning about pruritus to the drug facts label of the OTC versions. An estimated 62.7 million packages of OTC cetirizine and levocetirizine products were purchased by consumers in the US in 2022. Both medications can help relieve symptoms like sneezing, runny nose, itchy nose, and watery eyes caused by pollen and other seasonal allergens. They can also be used to manage year-round allergy symptoms triggered by dust mites, pet dander, or mold. Cetirizine was approved for oral use by prescription in December 1995 under the trade name Zyrtec (no longer sold as a prescription medicine) and approved for OTC use in November 2007. Meanwhile, levocetirizine was approved for oral use by prescription in May 2007 under the trade name Xyzal and approved for OTC use in January 2017. Patients have been advised to contact a health care professional if they develop severe itching after stopping prescription or OTC cetirizine or levocetirizine pills. Those who reported the uncomfortable side effect, said the itching typically occurred within a few days of stopping the medicines. Overall, the FDA says that it identified 209 cases of pruritus worldwide linked to cetirizine and levocetirizine cessation. This number only includes reports submitted to the FDA so experts suspect there might be additional cases. It notes that it is unsure why the medication causes the itching but 'many reports described widespread pruritus that required medical intervention after stopping these medicines, with a large number describing significant and persistent impact on quality of life and ability to function'.
