Give it time. You may find that you need to add a probiotic, especially after antibiotics. I seem to get about 6 months between pouchitis flairs if I take Visbiome(a probiotic) daily. If I don't take Visbiome my flairs are much more regular and worse.
Everyone is so different and it can be very difficult to know what works for you. The biggest thing to try and do is recognize the next flair and if it starts again make a plan.
I don't think everyone will agree but if you can do nothing all the better. Usually once experiencing pouchitis means it will reoccur and then you have to see what works for you.
If your doctor will give you a script and allow you to fill it as needed great! Some doctors won't period and some may not trust you until you have dealt with it a few times.
Probiotics come in many forms, most commonly used here are vsl3 and Visbiome. Both are expensive enough and it will depend on how much you need. Also availability, I can only access Visbiome. There are others but I don't believe any others are specifically for people with our medical needs and testing behind it.
Good luck
