Frequently asked questions about Chlorothiazide/methyldopa

What is chlorothiazide/methyldopa?
Chlorothiazide/methyldopa is made up of two medications that lower your blood pressure. Chlorothiazide is a thiazide diuretic (water pill) that works in the kidneys to remove extra water, which lowers blood pressure and gets rid of swelling. Methyldopa is an alpha-2 adrenergic receptor agonist that works by telling the brain to lower the activity of stress hormones. Fewer stress hormones leads to more relaxed blood vessels, which lowers blood pressure.
Is chlorothiazide/methyldopa still available?
No, chlorothiazide/methyldopa has been discontinued and is no longer available in the United States. It's not clear why chlorothiazide/methyldopa was discontinued.
Are there currently available medications that are used in place of chlorothiazide/methyldopa?
Yes. While the combination medication has been discontinued, both chlorothiazide and methyldopa are still available as single-ingredient medications. Although methyldopa isn't commonly used today, chlorothiazide (Diuril) is one of many available medications that works well for the treatment of high blood pressure. Ask your provider about other options to treat high blood pressure that are right for you.
