This is a post I saw and thought it was worth sharing. It could be much shorter to get the point across, but it is worth it, IMHO.
There is a generic version of Benadryl that is much cheaper than Benadryl. Benadryl does make you drowsy so it can be used as a sleep aid as well.
"For all of us in Rattlesnake country: I have learned something new that I thought was important enough that I wanted to pass on. Our hired man was bitten by a rattlesnake a few days ago. He was getting ready to bale and turned over a windrow to check the moisture and the snake was in it. It wrapped around his arm and bit him on the underside of the wrist. Luckily it was not a severe bite, the fang marks were clear, but not deep enough to draw blood. He came straight to the house and we got ice on it and had him to the hospital within an hour. I called ahead so the emergency room was ready for him. By the time he got there his arm was starting to swell to the shoulder and his throat was getting tight. The first thing the emergency room did was give him Benadryl. Apparently antivenom must be received within 4 hours of the snakebite, but the immediate threat is swelling and death of tissue, which was treated with the Benadryl. The swelling in his arm and throat started going down right away. The anti-venom medicine had to be prepared and was not ready for a couple of hours. He ended up getting two doses of antivenom and spent the night in the hospital, where they drew blood every three hours, but came home healthy the next day and went back to work.
I have always carried liquid Benadryl in all of the pickups because I am allergic to bee stings. After this happened I went out to check my supplies. All three of the bottles I had been carrying behind the seats in my emergency kits had been in there quite a while and had cracked and the liquid was gone. So that wasn’t going to be any help at all if we did need it.
My daughter, who is a nurse, told me to go buy the children’s chewable Benadryl instead. It is given according to body weight, so can be used for adults also, just give a larger dose. She said if you chew it and hold it in your mouth it will absorb just as fast or faster through the membranes of the mouth than from the stomach. The box doesn’t take much room and can be thrown into the glove compartment or saddle bags or a back pack if hiking, etc. Makes sense to me, and it might save a life."
