From the Guidelines

Steroids can indeed cause increased urination, particularly due to their effects on kidney function and blood glucose levels. This is evident from the treatment protocols outlined in the KDIGO 2021 guideline for the management of glomerular diseases 1. The guideline recommends high-dose glucocorticoids as first-line therapy for primary FSGS, with a starting dose of prednisone at 1 mg/kg/d, which can lead to increased urination as a side effect.

Some key points to consider:

  • The use of high-dose glucocorticoids can cause fluid retention initially, but may later lead to increased urination, especially at night (nocturia) 1.
  • Steroids can affect kidney function by altering sodium and water reabsorption in the renal tubules, leading to increased urine production 1.
  • The increased blood glucose levels caused by steroids can lead to osmotic diuresis, where excess sugar in the blood pulls water into the urine, resulting in increased urination 1.
  • It is essential to stay hydrated and consult with a healthcare provider if experiencing significantly increased urination while taking steroids, as this could indicate developing diabetes or other metabolic issues that require monitoring or adjustment of the medication regimen 1.

In terms of management, the guideline suggests a maximum duration of 16 weeks for high-dose glucocorticoid therapy, with a total duration of 6 months, including tapering 1. If patients experience severe side effects or do not respond to glucocorticoids, a trial of a calcineurin inhibitor (CNI) may be recommended 1.

From the FDA Drug Label

Cardio-Renal As sodium retention with resultant edema and potassium loss may occur in patients receiving corticosteroids, these agents should be used with caution in patients with congestive heart failure, hypertension, or renal insufficiency. Average and large doses of hydrocortisone or cortisone can cause elevation of blood pressure, salt and water retention, and increased excretion of potassium.

The use of steroids, such as prednisone, can lead to sodium retention and water retention, which may result in edema. However, this does not directly answer the question of whether steroids can cause increased urination. On the other hand, steroids can cause potassium loss and increased excretion of potassium, which may indirectly suggest an increase in urination. However, the FDA drug label does not directly support the answer to this question. The FDA drug label does not answer the question.

From the Research

Steroids and Urination

  • The relationship between steroids and increased urination is not directly addressed in the provided studies 2, 3, 4, 5, 6.
  • However, it is known that steroids can have various side effects, including changes in electrolyte balance and fluid retention 3.
  • Potassium-sparing diuretics, which are used to treat conditions such as hypokalemia, can increase urine production while retaining potassium in the body 2, 4, 5, 6.
  • Steroids may exacerbate preexisting conditions or present new medical conditions, including those related to electrolyte balance and fluid retention 3.
  • The use of potassium-sparing diuretics can help reduce potassium urinary loss and prevent hypokalemia in certain patients 5.
  • The effects of steroids on urination are not explicitly stated in the provided studies, but it is possible that they may contribute to increased urination in certain individuals, potentially through their effects on electrolyte balance and fluid retention 3.
