Summary

This study looked at medical records from over 1 million people in Denmark, Sweden, and Germany to check the safety of the drug NOCDURNA. NOCDURNA is used to treat frequent nighttime urination caused by a condition where the body makes too much urine at night. The researchers focused on finding cases of dangerously low sodium levels (hyponatremia) as a side effect. The study did not involve giving the drug to anyone; it simply analyzed existing health data.
