Can I take Acetazolamide and Duloxetine together?

Why this happens

Both acetazolamide and duloxetine can cause the body to lose sodium or affect how the body regulates salt and water. Acetazolamide is a diuretic (water tablet) that increases sodium excretion through urine, while duloxetine can cause the body to retain too much water, which dilutes the sodium in your blood. When used together, these effects can combine to significantly lower your sodium levels.

You should speak to your doctor before taking these medicines together. Your doctor may want to perform regular blood tests to monitor your sodium and electrolyte levels. Seek medical help immediately if you experience symptoms like severe headaches, confusion, muscle weakness, or feeling very unsteady on your feet. Avoid or strictly limit alcohol while taking these medicines, as it can worsen dizziness and dehydration.
