Chlorthalidone is a medication known as a diuretic. This means that it causes you to urinate more. Especially when you first start taking it. Chlorthalidone also lowers blood pressure. Because of these effects, some people feel dizzy, lightheaded, or have blurred vision when they first start taking chlorthalidone. These symptoms often go away once you get used to the medication.

Many doctors recommend being careful when you first start chlorthalidone. Go easy when performing activities that require coordination and being alert, such as driving. Remember to get up slowly from sitting or lying down to lessen dizziness. If you are one of the many people who don’t get dizzy, lightheaded, or have blurred vision, you can go back to your usual routine.

Diuretics can also make you more likely to get dehydrated. It is important to drink water when you exercise. Especially when it’s hot so you don’t get dehydrated.

Over time, you will see how your body reacts to chlorthalidone. You will find the routine that works best for you. Many people can do the activities they want without restrictions while taking chlorthalidone.

Imagine starting chlorthalidone as test-driving a new car. You wouldn’t speed down the highway in a brand new car without driving it around the parking lot first. The same is true for your blood pressure medicine. You need a little time to understand how your body will feel while on chlorthalidone.

Until you know, go slow!
