I don't know about bander's but I would think it would ok as long as if it's long term use you took the preventer just like everyone should. But a chemist should be able to tell you. It's like taking medication I've learnt recently that different tablets start to dissolve at different stages, eg as soon as you swallow, as it goes down into the stomach etc. I though tablets didn't start to do the job util they reached the stomach, so a banders might be different. But are you not at risk of ulcers, I don't know that much about the bands after care.
