About Adalat
NIFEDIPINE (Adalat® CC, Procardia XL®) is a calcium-channel blocker. Adalat affects the amount of calcium found in your heart and muscle cells. This results in relaxation of blood vessels, which can reduce the amount of work the heart has to do. Depending on the dosage form, nifedipine reduces attacks of chest pain (angina), and/or helps reduce high blood pressure (hypertension).
But It is not a cure.
Tablets is taken by mouth. Always check and follow the directions on the prescription label. Swallow the tablets whole with a drink of water; do not cut, crush or chew. Avoid taking nifedipine with grapefruit juice or grapefruit. Take your doses at regular intervals. Do not take your medicine more often then directed. Do not stop taking except on your prescriber's advice.
Contact your pediatrician or health care professional regarding the use of this medicine in children. Special care may be needed.
Elderly patients over 65 years old may have a stronger reaction to this medicine and need smaller doses.
If you miss a dose, take it as soon as you can. If it is almost time for your next dose, (less than 6 to 8 hours) take only that dose.
Do not ever take double or extra doses.

Frequently cheking your blood pressure and pulse rate regularly will help; this is important while you are taking nifedipine. Ask your prescriber or health care professional what your blood pressure and pulse rate should be and when you should contact him or her.
Do not suddenly stop taking nifedipine.
Always ask your prescriber or health care professional how to gradually reduce the dose.
You may feel dizzy or lightheaded. Do not drive, use machinery, or do anything that needs mental alertness until you know how nifedipine affects you. To reduce the risk of dizzy or fainting spells, do not sit or stand up quickly, especially if you are an older patient. Alcohol can make you more dizzy, increase flushing and rapid heartbeats.
Avoid alcoholic drinks.
