Medications to help pass kidney stones. Certain medications can improve your chances of passing a stone if you are experiencing an active stone episode. The most commonly used medication is tamsulosin (Flomax). Other similar medications used for this purpose include alfuzosin, nifedipine, doxazosin, and terazosin.
Stones between 2 to 4 mm take 12 days while 4-6 mm stones take about 22 days to pass out of the body. Kidney stones take about 40 days to pass out on its own without any medication of other intervention. Antispasmodics are usually prescribed to relax the ureter and ease the passage of kidney stones. When on antispasmodic, it may take about 5 to 7 days to pass out the kidney stone. If the kidney stone does not pass out on its own within 2 months, other medical intervention are considered.
