Depending on the reason you've been prescribed to use intermittent catheters, you may only need to catheterize once a day or multiple times a day. For example, some users with urine retention, may need to catheterize 5-6 times a day as the primary method of draining urine from the bladder.
Your healthcare professional will provide you with guidance on how many times you should be catheterizing throughout the day for your specific condition. Work with your doctor to help you define a cathing routine that works with your health and lifestyle needs.
