My mom is on gallstone medication treatment provided by my cousin sister.
I am concerned because she drinks beer 4 times per week and when she drinks she drinks 4-6 per day.
Does it render the medication less ineffective? or completely ruins it?
In general, it is never a good idea to self treat and take medicine from someone that isn't a doctor. Self diagnosing is how we get ourselves in medical trouble.
I understand the concern that she is drinking and wants to hide it. Do you feel she has a drinking problem? Would it be wise to work on her not drinking anymore? It may also make the digestive issues and idea that she is having gallbladder issues --- make those symptoms better.
