Felodipine is used to treat hypertension (high blood pressure) and prevent angina (chest pain). It works by relaxing blood vessels which allows blood to circulate more freely around your body. This lowers blood pressure, improves the efficiency of your heart and helps prevent the chest pain associated with angina.
Before taking felodipine
Before taking felodipine make sure your doctor or pharmacist knows:
- If you are pregnant, trying for a baby or breast-feeding.
- If you have liver problems.
- If you have angina and have chest pain when you are resting as well as during any exercise.
- If you have had a heart attack less than one month ago or have any other heart problems.
- If you have porphyria (a rare blood disorder).
- If you are taking other medicines, including those available to buy without a prescription, herbal and complementary medicines.
- If you have ever had an allergic reaction to this or any other medicine.
How to take felodipine
- Before starting this treatment, read the manufacturer's printed information leaflet from inside the pack.
- Take felodipine exactly as your doctor has told you. Take your doses in the morning unless your doctor has told you otherwise.
- You may take your doses before, during or after food.
- Swallow felodipine tablets whole with a drink of water. Do not break, crush or chew the tablets
- Do not drink grapefruit juice while you are on felodipine. This is because a chemical in grapefruit juice increases the amount of felodipine in your bloodstream. This makes side-effects more likely.
- If you forget to take a dose, take it as soon as you remember. If you do not remember until the following day, skip the missed dose. Do not take two doses together to make up for a forgotten dose.
Getting the most from your treatment
- Try to keep your regular appointments with your doctor. This is so your progress can be monitored.
- If you are having an operation or dental treatment, tell the person carrying out the treatment that you are taking felodipine.
- If you buy any medicines, always check with a pharmacist that they are safe to take with your other medicines.
- Suddenly stopping treatment with felodipine may cause problems. Your doctor may want you to reduce your dose gradually if this is necessary.
