Clinical course: The patient had 2 original doses and believed he had had 3 boosters. He had contracted Covid twice after the Covid vaccine and boosters. Back in May2025, the patient developed a virulent episode of vertigo where the patient could not stand up so the patient's daughter had to come over to walk dog. The vertigo lasted 2 days. The patient checked the website and found that vertigo was a possible side effect of COVID 19 but the patient did not have a COVID test at home to confirm if the patient had COVID again for the third time but suspect it may have been COVID. He thought maybe that was a sign so he searched and found this could be potential sign of Covid but didn't have a test to check so didn't know. Other than that episode of vertigo, the patient had no other symptoms. The patient's daughter brought a pill for nausea that let dissolve under tongue and swallow. She brought 2 pills but the patient took 1 and the vomiting stopped. Wanted to say around the middle of the month this happened. Was laying down watching TV not feeling well and was going to get water and sat up and just started vomiting. That was when the patient noticed he couldn't stand up. At first thought it was ear infection but didn't have any ear pain. Name of medication was printed really small. It is in a foil pack and says Ondansetron orally disintegrating and has Pheny and a bunch of other letters are on there also. Manufacturer starts with an A and the letters are blurred out.
