Chlorthalidone 12.5mg

Chlorthalidone 12.5mg Uses

Chlorthalidone 12.5mg is prescribed to:

• Manage high blood pressure (hypertension), reducing the risk of heart attacks, strokes, and kidney problems.
• Treat fluid retention (edema) caused by conditions like congestive heart failure, liver cirrhosis, or chronic kidney disease.
• Assist in the treatment of calcium-containing kidney stones by reducing urinary calcium levels.

How Does Chlorthalidone 12.5mg Work

Chlorthalidone works by inhibiting sodium and chloride reabsorption in the kidneys. This action increases urine output, reducing fluid retention and lowering blood pressure. By decreasing blood volume, it reduces strain on the heart and blood vessels.

How to Use Chlorthalidone 12.5mg

Side Effects

Common side effects may include:

• Increased urination
• Dizziness or lightheadedness, especially when standing up quickly

Drug Interactions

Chlorthalidone 12.5mg may interact with:

• Lithium, as Chlorthalidone may increase lithium levels, raising the risk of toxicity.

• Medications that lower potassium levels, such as corticosteroids or certain diuretics, increasing the risk of electrolyte imbalance.

Inform your doctor about all medications, supplements, and herbal products you are taking to avoid potential interactions.

Food Interactions
