The Zyrtec and Xyzal mark are placed by FDA for a new side effect. How do you know when to see your doctor

over the counter Allergies Like Cetirizine (ZYRTEC) and Levocetirizine (Xyzal) have become common drugs for many people in the United States with seasonal symptoms such as water and sneezing eyes, but now the FDA indicates that both medicine have a new danger.

The FDA (FDA) has recently published warning About these antihistamines, saying that patients who suddenly stop taking these medications after long -term use “may suffer from rare but severe itching.” Itching, also known as prureitus, occurred in patients who were taking Cetirizine and Levocetirizine daily for a few months or even years.

The FDA (FDA) estimates that 62.7 million beams without a prescription from Cetirizine and Levocetirizine were purchased in 2022.

However, there may be more cases, because these are those that were reported only to FDA. Interestingly, although most patients who suffered from this severe itch were taking these antihistamines for more than three months, some had this reaction less than one month after use.
