Busopan reaction?

I need help , I have been on Busupan for over 2 weeks for stomach spasms , yet to diagnos gall bladder or pancreas probs.
I went in to Emerg last nite in pain , The Doc ordered the reg treatment that seems to have been working for me IV , Busopan and morphine.
Well after 2 weeks of taking this med I some how went into anaphylactic shock after it was administered.
The other times I had this med was on a timed drip IV and in capsule form and was fine. This time it was a direct IV drip and i went in to shock.
Could this have possibly been a medical error on their behalf as i had already taken 2 capsules that I had TOLD them about and they were aware of befor administering MORE Busopan?

I used to suffer from stomach spams when I was younger. Yes, I think I can still remember the pain- it's so bad that I was vomitting and passing water- and most of the time- stuff wanna come out from both ends at the same time. I had cured myself of this condition and it is not with taking buscopan. I have just shared these tips with someone who had gone through the same problem- and I hope it will help you:
1. If you still have the pain, avoid anything with milk or its derivatives such as cheese. You may be also lactose intolerant.
2. Bloating is caused also by fermentation of sugar in your stomach- so minimize sugar from processed food such as cookies, chocolates and candies. Believe me, it helps a lot.
3. Get your digestion working well by taking more fruits that has high fiber content- red apples are excellent. Drink lots of water- it's important so that food does not get stuck.
4. Till you fully recover, don't take fried stuff, meat that are BBQ-ed or fried. If you want to have meat, then stick to the steamed ones.
5. Anything else that you imagine will move around and cause lots of 'deposits' in your intestine track such as Campbell soup or peanut butter must be avoided. Yeah, and avoid peanuts and reduce your beans intake because it causes bloating.
6. Take some oats.
7. No iced water with meals- it affects digestion.
Imagine eating fatty/processed food. As the food moved around the intestines, it will 'stain' the intestine wall. And what happens if nothing comes along to clean it? The food will literally rot in the intestines, causes bacteria to feed on the toxins and causing intense pain. Fiber and warm water are important to clean out the intestines.
If you try all of the above, not only you will be cured, but I believe you will gain more energy and you will not longer need buscopan, unless you have got food poisoning due to eating contaminated food.
