Most people who take an extra dose of chlorthalidone will be fine. But call your doctor right away if you don't feel well or have other concerns. Usually, your doctor will have you check your blood pressure at home and have you watch for symptoms for a day. Sometimes they may ask you to come into their office. Rarely, they will tell you to go to the emergency room. But usually you won’t need to.

When you take two doses of chlorthalidone, your blood pressure may drop too low. It is important to watch for symptoms like nausea, dizziness, or weakness.

Remember, it is best to take your medicine at the same time every day. Use a pillbox or other systems to help keep track of your pills. This will help you remember to take your medicine and help prevent you from accidentally taking an extra dose.

If you don't feel okay, call your doctor right away!
