Benadryl gives me palpitations. This was confirmed by a doctor friend a few years ago. He said that I was experiencing PACs, that they generally weren't dangerous, and that I should just avoid Benadryl. Since then, I have avoided all antihistamines. Unfortunately, this year my seasonal allergies have been bad. I talked with a pharmacist yesterday, who recommended staying away from Benadryl's family of antihistamines. Could I try 2nd gen antihistamines? If not, what could I try? Thank you!
