1) How do we deal with medicine ingredients be it pills or cream do we have to investigate ingredients ? If it’s cream to check if it’s najis or pills if it’s haraam?

2) What does a consistent doubter do in salah when he has dhan- inclination towards one side does he ignore the doubt or follow his dhan? Ruling of Ay Sistani says for a consistent doubter consider that you have done it but what if you have an inclination?

1- You don’t have to investigate the ingredients. You may assume it’s pure unless you know for sure that it is not.

2- Ignoring the doubt means that if you think you have done something then you simply consider it done and continue your prayer. So you can follow your inclination.
