FDA Warns: Common Allergy Meds May Cause Severe Rebound Itching

Rebound Itching: A Rare Side Effect of Long-Term Antihistamine Use Millions use antihistamines like Zyrtec and Xyzal daily to manage allergies. However, a rare but serious side effect, rebound itching, is gaining attention. The FDA recently warned healthcare providers about this issue, prompting allergists to advise patients on preventative measures. "Patients who take these medications daily for months or years may experience severe rebound itching after stopping," explains Dr. Rubin, MD, a board-certified allergist. He recommends switching to alternative antihistamines like Allegra or Claritin or suggests a slow tapering-off process under medical supervision. Dr. Rubin also notes that this side effect is often underreported and not well-studied. He stresses the importance of patient awareness and communication with their physicians. The key takeaway is that while antihistamines remain valuable for allergy management, patients should be aware of this potential side effect and seek professional guidance if needed. This awareness campaign aims to improve patient care and promote informed decision-making regarding allergy treatment.
