plite: Of course, you should try to follow your own rav regarding whether pills can contain chometz. I was just pointing out that if you can’t get the correct pills, then I think you will be fine anyway, since I am sure your rav would say to rely on this psak b’dieved, even if he doesn’t want to rely on it l’chatchila.
(Although, the easiest first step is to probably call and ask him if he relies on this psak l’chatchila, in which case you’re done.)
