It is one of the treatments of choice for Prinzmetal angina. It may be used to treat severe high blood pressure in pregnancy. Its use in preterm labor may allow more time for steroids to improve the baby's lung function and provide time for transfer of the mother to a well qualified medical facility before delivery.

Serious side effects may include low blood pressure and heart failure. There is tentative evidence that its use in pregnancy is safe; however, it is not recommended during breastfeeding.

It is on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system. It is available as a generic medication. The wholesale price in the developing world for the slow-release form is approximately US$1.90–3.80 per month. In the United States, it costs approximately $40–60 per month, depending on the dose.
