The answer to your question is no.

I want to make three more points, however:

Your doctor has prescribed lasix to keep you from becoming fluid overloaded (i.e. swelling in the legs, high blood pressure, difficulty with exercise, shortness of breath). Your diet, in particular the amount of fluid you drink, plays a huge role in your fluid status. Also, restricting the amount of salt you eat in your diet will play a huge role. ask your doctor about speaking to a nutritionist about salt and fluid intake and about learning how to read food labels to determine the amount of salt that is in the foods you eat. any foods that are frozen (tv dinners, etc) and canned soups contain large amounts of salt as preservatives. if you are able to fluid and salt restrict you will be going to the bathroom less, and may be able to cut your dose of lasix.

Second, it is unusual even for someone on lasix to be going to the bathroom every20 minutes. these symptoms may be due to an enlarged prostate or an irritated bladder(if you are a man) or problems with your pelvic floor muscles or bladder(if you are a woman). ask your doctor to evaluate you for these problems.

Third, the time you take lasix can influence your urinary frequency. if you are taking a dose of lasix at night this will certainly make you get up at night to go. sometimes you are able to take this second dose in mid afternoon to avoid getting up at night to go. ask your doctor about changing your dosing schedule if this is the case.

Not to my knowledge. Several patients that I care for ask this question a lot. Getting up and down every few minutes and all night can be quite annoying. Have you talked to your doctor about taking less of the medication and/or restricting fluids? Sometimes, this may help. However, I am only a nursing student and CNA. Do not attempt to alter your medication dosage or fluid intake without first consulting with a physician. This is only one of the many possible solutions.
