"BP Meds" doesn't mean anything. You mean BPH ( for Benign Prostatic Hyperplasia, non cancerous enlarged prostate, and can sometimes be BPE for Benign Prostatic Enlargement).? Or do you mean Blood Pressure medicine?

Some people use tamulosin for improved general blood pressure. The actual medication you are/were taking is what is needed to answer your question because different medications have different side effects.
