Let's take a minute to talk about your medication. 

This is labetalol. It helps the heart and blood vessels relax. Labetalol can be used to treat conditions like high blood pressure. It is important to take medicine for blood pressure every day, even if you feel fine. Otherwise, it can lead to serious problems, like a heart attack, stroke, blindness or kidney failure. 

You should take labetalol exactly as directed by your doctor. You may take it several times a day, so be sure to space your doses evenly. 

Most people tolerate this medicine well. Some common side effects could occur, like mild dizziness. To help reduce this, it's a good idea to stand slowly after sitting or lying down. You could feel a little tired. You should wait until you know how it affects you before doing activities that require you to be alert, like driving. Also, you might have nausea or notice tingling in your scalp. These effects are normal if they are mild, and should go away. If these or other side effects become reasons you want to stop taking this medicine, please talk to your doctor or pharmacist. But, do not stop taking it unless your doctor says it's okay. 

As with any medicine, rare but more serious side effects could occur. With medicines like labetalol, these include problems breathing, chest pain, or swelling in your hands, feet or legs. It could also cause a heartbeat to feel slow or irregular. If you notice these or other unusual changes to your body, you should call your doctor right away. 

For best results with labetalol, you should follow your doctor's advice about diet, exercise, and checking your own blood pressure and heart rate.
