Introduction

Taking one tablet of hydrochlorothiazide daily can be harmful to the body. Long-term use may lead to disturbances in water and electrolyte balance, excessively rapid drop in blood pressure, reduced kidney function, hyperglycemia, hyperuricemia, and other adverse effects. Hydrochlorothiazide is a diuretic that promotes the kidneys to excrete excess salt and water. This may cause electrolyte imbalances, leading to symptoms such as fatigue, arrhythmia, and muscle cramps.

Under normal circumstances, taking one hydrochlorothiazide tablet per day may have harmful effects on the body. Long-term use can lead to various adverse effects such as water and electrolyte disturbances, excessively rapid drop in blood pressure, reduced kidney function, hyperglycemia, hyperuricemia, etc. The specific analysis is as follows:

1. Water and Electrolyte Imbalance

Hydrochlorothiazide is a diuretic that promotes the kidneys to excrete excess salt and water. This may cause electrolyte imbalances, leading to symptoms such as fatigue, arrhythmia, and muscle cramps.

2. Excessively Rapid Drop in Blood Pressure

Hydrochlorothiazide reduces blood volume, thereby lowering blood pressure. If blood pressure drops too quickly or excessively, it may cause dizziness, vertigo, fainting, or even coma. Therefore, blood pressure should be closely monitored during hydrochlorothiazide use to avoid sudden drops.

3. Reduced Kidney Function

Long-term use or misuse of hydrochlorothiazide may adversely affect the kidneys. Due to its diuretic effect, it may increase the workload on the kidneys, potentially leading to impaired kidney function. Regular kidney function tests are recommended, and medical attention should be sought promptly if any discomfort occurs.

4. Hyperglycemia

The side effects of hydrochlorothiazide are mainly related to dosage and duration of treatment. One major effect is elevated blood glucose levels. The exact mechanism is not fully understood, but it is believed to primarily involve suppression of insulin release, resulting in impaired glucose tolerance and increased blood sugar levels.

5. Hyperuricemia

Hydrochlorothiazide interferes with renal tubular excretion of uric acid, and in a few cases, may trigger gout attacks. Because joint pain is usually absent, hyperuricemia may easily be overlooked.

In addition, some allergic reactions such as rashes and urticaria may occur, although these are relatively rare. Therefore, long-term use should be avoided as much as possible.

Is the antihypertensive effect of losartan potassium and hydrochlorothiazide tablets good?

The antihypertensive effect of losartan potassium and hydrochlorothiazide tablets is generally good, making it suitable for hypertensive patients who require two medications to control their blood pressure. Since losartan potassium and hydrochlorothiazide tablets combine two antihypertensive drugs, their efficacy is superior to that of using a single medication alone. Patients requiring combination antihypertensive therapy may use this medication under the guidance of a physician.
