Package leaflet: Information for the patient



The name of this medicine is Neofel XL Prolonged Release Tablets (felodipine), which will be referred to as Neofel XL throughout this leaflet.

  • Keep this leaflet. You may need to read it again.
  • If you have further questions, please ask your doctor or your pharmacist.
  • This medicine has been prescribed for you only. Do not pass it on to others; it may harm them, even if their signs of illness are the same as yours.

The active ingredient in Neofel XL is felodipine which is one of a group of medicines called dihydropyridine calcium antagonists. These work by blocking the entry of calcium into muscle cells.

Neofel XL (felodipine) affects the muscle in blood vessels more than other muscles. It causes a relaxation of the muscle and a widening of the blood vessels. As the blood vessels get wider, blood pressure falls and the heart does not need to work so hard to pump blood around the body, reducing the risk of angina.

Neofel XL is used to treat high blood pressure (hypertension) and prevent attacks of angina (a painful condition where there is a lack of blood and oxygen to the heart).


Do not take Neofel XL:

  • If you are pregnant, planning to become pregnant or you suspect you are pregnant
  • If you are allergic to felodipine or any of the other ingredients of this medicine (listed in Section 6)
  • If you suffer from uncompensated heart failure
  • If you have had a heart attack (myocardial infarction) within the last 4 weeks
  • If you suffer from severe chest pain due to a lack of blood and oxygen to the heart (unstable angina pectoris)
  • If you have narrowing of one of the valves in the heart (aortic stenosis)
  • If you have or develop cardiogenic shock (where the heart is unable to supply sufficient blood to the body)

Warnings and precautions

Talk to your doctor or pharmacist before taking Neofel XL if you:

  • have a rapid heartbeat (tachycardia)
  • have a liver disorder
  • are breast-feeding
  • suffer from a condition which affects the chambers of your heart and may prevent them from working properly (left ventricular dysfunction)

Neofel XL like other blood-pressure lowering medicinal products may in rare cases lead to pronounced low blood pressure which in some patients may result in an inadequate supply of blood to the heart. Symptoms of excessive low blood pressure and inadequate blood supply to the heart itself, frequently include dizziness and chest pain. If you experience these symptoms, seek emergency care immediately.

Taking Neofel XL may cause your gums to become swollen. Practice good oral hygiene to help avoid your gums from swelling (see section 4).


The use of Neofel XL is not recommended in children

Other medicines and Neofel XL

Tell your doctor if you are taking, have recently taken or might take any other medicines. Medicines containing St. John’s wort (Hypericum perforatum) (herbal product used to treat depression) may reduce the effect of Neofel XL and should therefore be avoided.

Below are examples of some medicines/herbal remedies which may decrease or increase the effect of Neofel XL:

  • other medicines for treating high blood pressure including diuretics (water tablets)
  • cimetidine for the treatment of stomach ulcers
  • erythromycin, clarithromycin and rifampicin used to treat bacterial infections
  • nelfinavir, ritonavir, indinavir, efavirenz and nevirapine for the treatment of HIV
  • ketoconazole and itraconazole used to treat fungal infections
  • medicines for the treatment of convulsions or epilepsy (e.g. phenytoin, carbamazepine or phenobarbital).
  • tacrolimus an immunosuppressive drug used to prevent organ transplant rejection

It may still be all right for you to take Neofel XL and your doctor will be able to decide what is suitable for you. Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.
