HCTZ Dosage

For high blood pressure control with HCTZ, dosage recommendations typically start at 25 mg once a day. Depending on your response to the medication, your healthcare provider may adjust your dosage accordingly. The suggested dosage for treating water retention varies between 25 mg and 100 mg, taken in a single dose or divided and taken more frequently. Generally, the recommended HCTZ dosage for infants and children is 0.5 mg to 1 mg per pound of body weight each day.

HCTZ Dosing: An Overview

The dose of HCTZ (hydrochlorothiazide or HCT) that your healthcare provider recommends will vary depending on a number of factors, including:
  • Other medical conditions you may have
  • Other medications you may be currently taking
  • How you respond to HCTZ.
As is always the case, do not adjust your dose unless your healthcare provider specifically instructs you to do so.

HCTZ Dosing for High Blood Pressure

The recommended starting dose of HCTZ for treating high blood pressure is 25 mg once daily. Based on the initial blood pressure response and/or side effects of HCTZ, the dosage may be increased up to 50 mg per day. With each change in dosage, it may take several weeks to see the full effects of HCTZ on lowering blood pressure.

HCTZ Dosing for Water Retention

The recommended dose of HCTZ for fluid retention (edema) can vary between 25 mg and 100 mg daily (taken as a single dose or divided and taken more frequently). Some people will only need to take HCTZ when they need it (when they are experiencing water retention), while others may need to take HCTZ on a daily basis.

HCTZ Dosing for Infants and Children

Usually, the dose of HCTZ for infants and children is 0.5 mg to 1 mg per pound per day. This can be given as one daily dose or split up into two doses per day. The dose should not exceed 37.5 mg total per day for infants up to two years old or 100 mg per day for children two to twelve years old. In some infants less than six months old, higher doses (up to 1.5 mg per pound per day) may be necessary.
