Nifedipine, sold under the brand name Procardia among others, is a calcium channel blocker medication used to manage angina, high blood pressure, Raynaud's phenomenon, and premature labor.[2] It is one of the treatments of choice for Prinzmetal angina.[2] It may be used to treat severe high blood pressure in pregnancy.[2] 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.[2] It is a calcium channel blocker of the dihydropyridine type.[2] Nifedipine is taken by mouth and comes in fast- and slow-release formulations.[2]

Common side effects include lightheadedness, headache, feeling tired, leg swelling, cough, and shortness of breath.[2] Serious side effects may include low blood pressure and heart failure.[2] Nifedipine is considered safe in pregnancy and breastfeeding.[5]

Nifedipine was patented in 1967, and approved for use in the United States in 1981.[2][6][7] It is on the World Health Organization's List of Essential Medicines.[8] It is available as a generic medication.[2] In 2022, it was the 151st most commonly prescribed medication in the United States, with more than 3 million prescriptions.[9][10]
