allegra is evil?

after going to the school clinic for allergies after moving, she told me that i should try allegra rather than zyrtec as i’d had weird side effects w/ zyrtec.

so im in like? week six of allegra and have recently been having rlly awful chest pain on the right side, wheezy breath, my eyesight randomly will get really blurry, and my allergy symptoms are barely better. i planned on just going to the clinic and seeing if they could tell me whats up, but gov shutdown is killing my insurance rn (its like a whole thing, i cannot explain it here)

so after sleuthing the internet for a while (and lurking in this sub) apparently these are like? known allegra symptoms?

so i’m gonna stop taking allegra for a bit and seeing if it will help, but i will need smth else bc the allergies are still very real and awful. any otc ideas till i can get my insurance in order?
