Nifedipin is used to lower hypertension, to treat angina and blood circulation disorder.
Nifedipin belongs to a class of medications known as calcium channel blockers. It works by relaxing blood vessels so blood can flow more easily. This medication is used to prevent certain types of chest pain (angina). It should not be used to treat attacks of chest pain when they occur. This medication may also be used to treat a certain blood circulation disorder (Raynaud's syndrome).
Take Nifedipin exactly as prescribed by your doctor. Take this medication by mouth, usually 3 times daily with or without food. Swallow this medication whole. The recommended starting dose for treating chest pain (angina) is 10 mg three times daily. If necessary, your doctor may increase your dose (up to 30 mg four times daily) to control your chest pain.
Before taking Nifedipin you should talk with your doctor if you have heart disease, congestive heart failure, low blood pressure, upcoming surgery, aortic stenosis, kidney disease, liver disease, any allergies. The elderly people appear to be more sensitive to the medication. This drug may make you dizzy. Do not drive or perform tasks that require alertness. Limit alcoholic beverages. Alcohol may further lower blood pressure and increase drowsiness or dizziness. Avoid eating grapefruit or drinking grapefruit juice while being treated with this medication.
You should not take Nifedipin if you are allergic to it, nifedipine, or any of the inactive components of the drug. Let your healthcare provider know if you are pregnant or breastfeeding.
