Consumer Medicine Information

What is in this leaflet

This leaflet answers some of the common questions people ask about FELODUR ER. It does not contain all the information that is known about FELODUR ER.

It does not take the place of talking to your doctor or pharmacist.

All medicines have risks and benefits. Your doctor will have weighed the risks of you taking FELODUR ER against the benefits they expect it will have for you.

If you have any concerns about taking this medicine, ask your doctor or pharmacist.

Keep this leaflet with the medicine. You may need to read it again.

What FELODUR ER is for

FELODUR ER is used to treat high blood pressure, also called hypertension. FELODUR ER lowers blood pressure by dilating (expanding) small blood vessels, letting the blood be pumped around the body more easily.

Your doctor will have explained why you are being treated with FELODUR ER and told you what dose to take.

The ER in FELODUR ER stands for Extended Release. This means that the tablets are designed to work over a 24 hour period.

FELODUR 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.

Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed this medicine for another reason.

FELODUR ER is only available with a doctor’s prescription.

FELODUR ER is not addictive

Some of the symptoms of an allergic reaction may include, tightness of the chest, wheezing, coughing or difficulty breathing; swelling of the face, lips, tongue or other parts of the body; rash, itching or hives.

Tell your doctor as soon as possible if you become pregnant while using FELODUR ER.

Tell your doctor if you are breastfeeding or intend to breastfeed before you take FELODUR ER. Your baby can take in FELODUR ER from breast milk if you are breastfeeding, but it is unlikely to affect the infant when the mother is taking doses within the normal range for her treatment.

Taking other medicines

Some medicines and FELODUR ER may interfere with each other. These include:

  • cimetidine – a medicine used to treat stomach ulcers or heartburn
  • medicines used to treat infections such as erythromycin and rifampicin

  • St John’s Wort – a herbal remedy used to treat mood disorders

These medicines may be affected by FELODUR ER or may affect the way FELODUR ER works. You may need different amounts of your medicines, or may need to take different medicines.

Your doctor can tell you what to do if you are taking any of these medicines.

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.

Your doctor and pharmacist have more information on medicines to be careful with or avoid while taking this medicine. If you are unsure about any medicine you are taking you should check with your doctor or pharmacist.

If you have not told your doctor, dentist or pharmacist about any of these things, tell them before you take any FELODUR ER.


How much to take

The usual starting dose of FELODUR ER is one 2.5 mg or 5mg tablet taken once daily.

Your doctor will check your progress and if needed, increase your dose of FELODUR ER. Sometimes the dose will be as high as 20mg once a day.

If you have to take more than one tablet, you must take them together.

Swallow FELODUR 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 does not matter if you take FELODUR ER with food or not, but you must not take it with grapefruit juice. Grapefruit juice may increase the effect of FELODUR ER.

If you forget to take it

If you forget a dose, take it as soon as you remember, as long as it is more than 12 hours before the next dose is due.

If it is less than 12 hours until your next dose, skip the dose you missed and take your next dose when you are meant to.

Do not take a double dose to make up for the dose that you missed. If you have trouble remembering when to take your medicine, ask your pharmacist for some hints.

How long to take it

Take FELODUR ER for as long as your doctor tells you to.

FELODUR ER must be taken every day.

FELODUR ER helps control your high blood pressure, but does not cure 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 Accident and Emergency at your nearest hospital immediately if you think that you or anyone else may have taken too much FELODUR ER even if there are no signs of discomfort or poisoning.

If you take too much FELODUR ER you may experience a headache, a slow heartbeat, very low blood pressure, dizziness, tiredness or feel sick (nausea).

While you are using it

Things you must do

If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking FELODUR ER.

Tell any other doctors, dentists, and pharmacists who treat you that you are taking this medicine.

If you become pregnant while taking this medicine, tell your doctor immediately.

Keep all of your doctor’s appointments so that your progress can be checked.

Things you must not do

Do not take FELODUR ER with grapefruit juice. Grapefruit juice may increase the effect of FELODUR ER.

Do not stop taking FELODUR ER unless you have discussed it with your doctor.

Do not use this medicine to treat any other complaint unless your doctor tells you to.

Do not give this medicine to anyone else, even if they have the same condition as you.

Things to be careful of

Be careful driving or operating machinery until you know how FELODUR ER affects you. When you start taking FELODUR ER, whether you are changing from another medicine for high blood pressure or not, you may feel dizzy or faint due to the drop in your blood pressure.

Be careful when drinking alcohol while you are using FELODUR ER. Please talk to your doctor or pharmacist about these possibilities.

Side effects

Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking FELODUR ER. FELODUR ER helps most people with high blood pressure, but it may have unwanted side-effects in a few people.

All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical treatment if you get some of the side effects.

Ask your doctor or pharmacist to answer any questions you may have.

Tell your doctor if you notice any of the following and they worry you:

  • headache
  • swelling of the ankles
  • dizziness
  • flushing
  • palpitations (feeling of heart pounding)
  • fatigue (tiredness)

These side effects usually go away or get less with time. If they do occur, it mostly happens at the beginning of treatment, or when the dose is increased.

Other side effects you should tell your doctor about if they worry you include:

  • nausea (feeling sick)
  • frequent urination
  • impotence / sexual dysfunction
  • stomach pain
  • pain, swelling or redness in your gums
  • fever
  • increased sensitivity of the skin to sunlight
  • sensation of burning, prickling, numbness, “pins and needles”

These side effects are usually mild.

Tell your doctor immediately or go to Accident and Emergency at your nearest hospital if you notice any of the following:

  • skin rash
  • fainting
  • chest pain
  • rapid heart beat

These are serious side effects. You may need urgent medical attention.

If any of the following happen, stop taking FELODUR ER and tell your doctor immediately or go to Accident and Emergency at your nearest hospital.

  • harsh sounds or difficulty when breathing

These are very serious side effects. If you have them, you may have had a serious (allergic) reaction to FELODUR ER. You may need urgent medical attention or hospitalisation.

Tell your doctor if you notice anything else that is making you feel unwell. Some people may get other side effects while taking FELODUR ER.

After using it


Keep your tablets in the blister pack until it is time to take them. If you take FELODUR ER out of the blister pack it will not keep well.

Keep it in a cool dry place where the temperature stays below 25°C.

Do not store FELODUR ER or any other medicine in the bathroom or near a sink.

Do not leave it in the car on hot days. Heat and dampness can destroy some medicines.

Keep it where young children cannot reach it. A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.


Ask your pharmacist what to do with any tablets you have left over if your doctor tells you to stop taking them, or you find that the expiry date has passed.
