Hydrochlorothiazide

Hydrochlorothiazide (HCT or HCTZ) is a diuretic or “water pills”.  It is prescribed mainly for the treatment of mild to moderate hypertension or high blood pressure. Other uses include:

• Swelling due to fluid buildup in the body tissue caused by various medical problems
• Excess fluid retention due to treatment with corticosteroids
• Decrease the risk of kidney stones
• Renal tubular acidosis
• Diabetes insipidus

HCTZ acts on the kidney. It causes the kidney to increase the amount of salt being filtered out of the blood and into the urine. As salt is being filtered out, it draws water along them. Removing excess water and salt from the blood decreases the volume of fluid circulating in the blood vessels. This results in a decrease in the blood pressure within the blood vessels. 

Why Buy Hydrochlorothiazide?

It’s one of the most common types of blood pressure medication. It’s a well-tolerated diuretic that’s often the first choice treatment for hypertension. HCTZ is a good choice for patients with high blood pressure and osteoporosis as it raises the body’s calcium level.  It lowers the blood pressure by getting rid of excess water and salt through the kidney with very few side effects. It can also treat several other conditions including heart failure and kidney problems.

How to Take Hydrochlorothiazide?

Take HCTZ exactly as directed by your physician. Take it in the morning as you need to visit the toilet more often or you may take it at least 4 hours before bedtime. It is usually taken once or twice a day. If you are using this medication to treat edema, you may need to take it daily or only on certain days of the week. Continue taking this drug even if you feel well. Do not take more than what is prescribed to you.

Things to Remember

• HCTZ can cause lots of potassium being filtered out of the blood. This can sometimes cause a decrease in the level of potassium or hypokalaemia. A decrease in potassium level can be dangerous especially for people with heart or liver disease.
• This medication can cause dizziness and fatigue. Take extra care when doing activities that require mental alertness like driving and operating machinery.
• Avoid drinking alcoholic beverages as it may enhance the effect of this drug.
• Have a regular blood test to monitor the function of your kidney, the level of sodium and potassium in your body.
• HCTZ can turn your urine a blue color. This is only visible in certain light. This is totally normal and you have nothing to worry about.
