I just got an email from my sister that she spent several hours in the ER yesterday.
She's always had bad allergies and this year has been worse than most. Her doctor gave her a new allergy med and she took it for the first time yesterday morning. A short time later she got dizzy and had to sit. Then lay down. They she got nauseaus and broke into a sweat and within seconds passed out. Luckily my bil was home and called 911 and they got her to the hospital. They believe she had an allergic reaction, plus she was slightly dehydrated because her throat was so sore from her allergies that she wasn't eating/drinking enough. She only has vague memories of the first part of the time in the ER - but she was able to go back home and is on the mend. Just a scary time and no, she won't take that allergy medication again.
How scary, we can think we have no allergies to medication - then boom - you do. Hopefully they are right and that was the trigger and it was a one-time only situation. She emailed me that she can't get sick now - cuz she knows I'd want to come - and she knows I'm busy elsewhere.
