Patient leaflet - Felogen XL 5 mg prolonged-release tablets

1. What Felogen XL is and what it is used for

Felogen XL contains felodipine, which belongs to a group of medicines called calcium antagonists. It lowers blood pressure by dilating small blood vessels. It does not negatively affect the heart function.

Felogen XL is used in the treatment of high blood pressure (hypertension) and heart and chest pain brought on by, for example, exercise or stress (angina pectoris).

2. What you need to know before you take Felogen XL

Do not take Felogen XL if:

  • You are pregnant. You should tell your doctor as soon as possible if you become pregnant while taking this medicine
  • You are allergic to felodipine or any of the other ingredients of this medicine (listed in section 6)
  • You suffer from uncompensated heart failure
  • You have acute myocardial infarction (heart attack)
  • You have chest pain of recent onset, or angina pectoris that is lasting for more than 15 minutes or longer, or is more severe than usual
  • You have disease of a heart valve or heart muscle, until you have talked to your doctor.

Warnings and precautions

Felodipine, like other blood pressure-lowering medicines, may in rare cases lead to pronounced low blood pressure which in some patients may result in an inadequate blood supply to the heart muscles. 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.

Talk to your doctor or pharmacist before taking Felogen XL, especially if you have problems with your liver

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

Children

The use of felodipine is not recommended in children.

Other medicines and Felogen XL

  • Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. Some medicines or herbal remedies can affect treatment with felodipine. Examples are:cimetidine (medicine to treat stomach ulcers)
  • erythromycin (medicine to treat bacterial infections)
  • itraconazole or ketoconazole (medicines to treat fungal infections)
  • medicines to treat HIV infection (such as ritonavir, efavirenz, nevirapine)
  • phenytoin or carbamazepine (medicines to treat epilepsy)
  • rifampicin (medicine to treat infections)
  • barbiturates (medicine to treat anxiety, sleeping problems and epilepsy)
  • tacrolimus (medicine used after organ transplants)

Medicines containing St John’s wort (Hypericum perforatum) (a herbal product used to treat depression) may reduce the effect of felodipine and should therefore be avoided

Felogen XL with food and drink

Do not drink grapefruit juice if you are taking this medicine, as this may increase the effect of Felogen XL and the risk of side effects.

Pregnancy and breast-feeding

Do not take Felogen XL if you are pregnant.

Tell your doctor if you are breast-feeding or are about to start breast-feeding. Felodipine is not recommended for mothers who are breast-feeding and your doctor may choose another treatment for you if you wish to breast-feed.

Driving and using machines

Felodipine can have minor or moderate influence on your ability to drive and use machines. If you experience headache, nausea, dizziness or fatigue your ability to react may be impaired. Caution is recommended especially at the start of treatment.
