Drinking alcohol doesn't influence how well Betmiga works. However, it's important to note that alcohol can exacerbate symptoms of urinary frequency and urgency, making them worse. Alcohol consumption can also affect your sleep patterns and increase the likelihood of needing to visit the bathroom during the night. So, while it won't directly interfere with the effectiveness of Betmiga, it’s advisable to keep alcohol intake to a minimum to help you manage your incontinence symptoms effectively.
