What to do if you miss a dose of Microzide

Missing a dose of Microzide (Hydrochlorothiazide) is common — most people will skip a dose at some point during a course. The right action depends on how long since the missed dose and whether Microzide is taken event-driven or daily at 12.5mg, 25mg, 50mg. The wrong action — doubling up — is not recommended.

For daily Microzide

If Microzide is taken daily for a chronic condition, take the missed dose as soon as you remember, unless it is almost time for the next scheduled dose. In that case skip the missed dose and continue normally. According to the prescribing information for Hydrochlorothiazide, two doses should never be taken close together to "make up" for a miss.

For event-driven Microzide

If Microzide is used as needed (not on a fixed schedule), there is no "missed dose" in the conventional sense — simply take the planned dose when needed and observe the recommended gap before re-dosing. Hydrochlorothiazide blocks the sodium-chloride symporter in the distal convoluted tubule of the kidney, reducing sodium reabsorption and producing modest diuresis.

Frequently asked questions

Should I double the dose if I missed Microzide? ▾

No. Doubling doses of Microzide to compensate is not recommended at any 12.5mg, 25mg, 50mg strength and increases the risk of side effects without improving efficacy. Take the next scheduled dose normally.

How many missed doses are too many? ▾

Occasional missed doses of Microzide are usually inconsequential. Repeated missed doses can compromise the therapeutic effect — for chronic conditions like those treated with Diuretics, consistent dosing matters. If adherence is hard, discuss reminders, simpler schedules or alternative formulations with the prescriber.
