Frequent urination, especially at night, can occur after starting lithium because it reduces the kidneys’ ability to concentrate urine. Since your symptoms began soon after initiating lithium, please discuss this with your treating psychiatrist before making any changes to the medication. Meanwhile, maintain adequate hydration, avoid reducing water intake on your own, and get your serum lithium level, kidney function tests, electrolytes, and urine output assessed. If the nocturia is persistent or severe, your psychiatrist may consider dose adjustment, changing the formulation or timing, or evaluating for lithium-induced nephrogenic diabetes insipidus after ruling out other causes such as diabetes mellitus or a urinary tract infection.

Waking up every hour to urinate after starting Lithium Carbonate 400 SR is a well-recognized side effect known as lithium-induced polyuria and nocturia.
Lithium can interfere with the kidneys' ability to respond to antidiuretic hormone (ADH), causing them to excrete larger volumes of diluted urine. While this is a common physiological reaction when initiating therapy, severe nocturia that disrupts your sleep every hour requires attention, as adequate rest is essential for managing bipolar disorder.
Next Steps
Consult Your Psychiatrist Promptly: Inform your doctor about the severity of this symptom. They may consider consolidating your dose to a single nighttime schedule, adjusting the timing, or checking your lithium levels.
Monitor Fluid Intake Timing: Stay well-hydrated throughout the day to avoid dehydration, but try to limit heavy fluid consumption in the late evening or right before going to bed.
Get a Baseline Kidney Function Test: Ensure your doctor checks your renal profile, including serum creatinine, blood urea nitrogen (BUN), and urine specific gravity, to track your baseline kidney function.
Health Tips
Do not abruptly stop taking your Lithium Carbonate 400 SR or lower your dose on your own. Sudden discontinuation can rapidly trigger a relapse of manic or depressive bipolar episodes.
Do Not Restrict Fluids Excessively: While shifting your fluid intake away from bedtime is helpful, do not severely restrict your overall water intake during the day. Dehydration can cause lithium levels in your blood to spike dangerously, increasing the risk of toxicity.
