About CTD-12.5 Tablet

CTD-12.5 Tablet is a prescription medicine used to treat high blood pressure and reduce swelling caused by excess fluid in your body. By helping your kidneys remove extra salt and water, this medication decreases the workload on your heart and blood vessels. Using it consistently helps protect your long-term health by reducing the risk of strokes and heart attacks.

For the best results, you should take CTD-12.5 Tablet at the same time every day, preferably in the morning to prevent having to wake up during the night to urinate.

Combining this treatment with a low-salt diet and regular, doctor-approved exercise will help you achieve the best possible results.

While taking this medicine, you may experience mild side effects like an increased need to urinate, mild dizziness, or a temporary headache. These symptoms are usually manageable, but you must contact your doctor immediately if you experience serious side effects such as severe muscle cramps, extreme thirst, or an irregular heartbeat.

How CTD-12.5 Tablet Works

CTD-12.5 Tablet contains chlorthalidone, which belongs to a group of medicines known as diuretics, commonly called 'water pills.' It acts directly on the filtering units of your kidneys to increase the amount of sodium and water that your body removes from your bloodstream and excretes through your urine. As your body sheds this extra salt and water, the total volume of blood circulating through your blood vessels goes down. This reduction in fluid volume lowers the pressure against your artery walls and decreases the strain on your heart, allowing it to pump blood more easily throughout your body.
