About 2 weeks ago we had to get refills on some of my grandma's meds, and we were out. So, the pharmacy faxed the doctor for more refills. She had ended up switching a couple of her meds, because of the blood results from about a month ago when my grandma went in for a UTI. She takes meds 3 times a day, every 8 hours. Since they switched them, whenever I give her the night ones I start getting dizzy, I start having a little trouble breathing, and I start sneezing. I don't know why. It doesn't happen with her other two medications. Each one she takes 5 pills, all of which are different. Is there anything I can do about this? I can't just not give her her meds, and I don't know which one (or ones) are causing it. I am a "very allergic" person. I have a histamine and chemical sensitivity. Along with asthma gerd, pcos, and allergic to multiple medications.
