If you can breathe, speak, and swallow saliva, it is unlikely to be blocking your airway. A levocetirizine 5 mg tablet will usually dissolve or pass into the stomach, but it can briefly irritate the esophagus and leave a “stuck” sensation.

Do this now:

Call emergency services now if you cannot breathe properly, cannot speak, have noisy breathing, blue lips, or are unable to swallow saliva/drooling.

Get urgent medical advice today if you have persistent or worsening throat/chest pain, painful swallowing, repeated vomiting, coughing/wheezing, or the stuck feeling does not improve over the next few hours. A tablet lodged in the esophagus can occasionally cause irritation, called pill esophagitis, particularly if taken with little water or just before lying down, as described by Poison Control.
