Drug Name: Nifedipine ER
Brand Names: Adalat, Adalat CC, Nifedical XL, Procardia XL, Procardia
Generic Name: Nifedipine
Uses: Nifedipine is used to treat high blood pressure. It works by relaxing your blood vessels which then reduces the amount of work the heart needs to do. It also increases the heart’s supply of blood and oxygen which helps control chest angina. Nifedipine though is not a cure, it can just prevent the attacks or the symptoms exhibited in chest angina and reduce high blood pressure. Once angina attacks happen, taking nifedipine cannot treat these attacks. Other conditions that may be treated by nifedipine are migraine headaches, Raynaud’s syndrome, congestive heart failure and cardiomyopathy.
How to use: The usual dose of nifedipine ER is three times a day, either an hour or 2 hours after a meal.
