How long does flomax take to work for kidney stones?

From what I have seen in my family, Flomax starts relaxing the urinary tract within 1 to 3 days, which helps the stone pass more easily. Along with it, you must drink 3 to 4 liters of water daily to push the stone out. It is a simple and cheap solution that really works.

It usually takes a few days, around 3 to 7 days, for Flomax to help pass the stone. While you take it, drinking warm barley water can also help ease the flow. But if you get sudden severe pain or blood in urine, go to the doctor immediately.

My urologist explained that Flomax (tamsulosin) starts relaxing the bladder neck muscles within 24 to 48 hours, but it can take anywhere from 1 to 2 weeks for the stone to actually pass out of the system. He also advised taking it 30 minutes after the same meal every day.

Yes, it generally takes about 2 to 5 days to start working. Just make sure to take it at the same time every day as prescribed by your doctor.
