What PLENDIL ER is for
Plendil ER lowers blood pressure by dilating (expanding) small blood vessels away from the heart, letting the blood be pumped around the body more easily.
Your doctor will have explained why you are being treated with Plendil ER and told you what dose to take.
The ER in Plendil ER stands for Extended Release. This means that the tablets are designed to work over a 24 hour period.
Plendil ER contains felodipine, which belongs to the family of medicines known as calcium channel blockers. These medicines do not change the way the body takes in calcium from food.
Follow all directions given to you by your doctor carefully. They may differ from the information contained in this leaflet.
Your doctor may prescribe this medicine for another use. Ask your doctor if you want more information.

Taking PLENDIL ER
How much to take
If you are taking other drugs which lower blood pressure, your doctor may need to change the dose of them to obtain the best results for you.
The usual starting dose is a 2.5 or 5 mg tablet taken once daily.
Your doctor will check your progress and if it is needed, increase your dose of Plendil ER. Sometimes the dose will be as high as 20mg a day.
If you have to take more than one tablet, you must take them together.
Swallow PLENDIL ER tablets whole and wash them down with a glass of water. They must not be divided, crushed or chewed. If they are broken or crushed they will not work over 24 hours as they are supposed to.
It doesn't matter if you take Plendil ER with food or not, but you must not take it with grapefruit juice. Grapefruit juice, but not other fruit juices, may increase the effect of Plendil ER.
If you forget to take it
If you forget a dose, take it as soon as you remember, as long as it is at least 12 hours before the next dose is due.
Don't double the dose.
If you have trouble remembering when to take your medicine, ask your pharmacist for some hints.
How long to take it
Treatment of high blood pressure is necessary in most people for the rest of their lives. Ask your doctor to explain the reasons for this.
Telephone your doctor, the Poisons Information Centre (13 11 26) or go to casualty at your nearest hospital immediately if you think that you or anyone else may have taken too much Plendil ER even if there are no signs of discomfort or poisoning. If you take too much Plendil ER you will probably get a headache and feel sick (nausea), dizzy and very tired.
