For some medications in Thiazide diuretic, mood changes are part of the central indication. For others, mood changes are listed in the prescribing information for Hydrochlorothiazide as side effects in a small subset of users, sometimes appearing in the first weeks of therapy and resolving spontaneously. Hydrochlorothiazide blocks the sodium-chloride symporter in the distal convoluted tubule of the kidney, reducing sodium reabsorption and producing modest diuresis.

Mild irritability or transient low mood in the first weeks on Hydrochlorothiazide at 12.5mg, 25mg, 50mg is common and often improves. Persistent low mood, new anxiety that interferes with daily life, suicidal thoughts, or any sudden severe mood change warrants prompt review with the prescriber.
