Before taking isradipine
Before taking isradipine make sure your doctor or pharmacist knows:
- If you are pregnant, trying for a baby or breast-feeding.
- If you have liver or kidney problems.
- 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 isradipine
- Before starting this treatment, read the manufacturer's printed information leaflet from inside the pack.
- Take isradipine exactly as your doctor has told you. It is usually taken twice each day, with the doses preferably being 12 hours apart.
- You may take your doses before, during or after food.
- Do not drink grapefruit juice while you are on isradipine. This is because a chemical in grapefruit juice increases the amount of isradipine in your bloodstream. This makes side-effects more likely.
- Try to take isradipine at the same times each day to avoid missing any doses.
- If you forget to take a dose, take it as soon as you remember unless it is nearly time for your next dose, in which case leave out 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 buy any medicines, always check with a pharmacist that they are safe to take with your other medicines.
- If you are having an operation or dental treatment, tell the person carrying out the treatment that you are taking isradipine.
- Suddenly stopping treatment with isradipine may cause problems. Your doctor may want you to reduce your dose gradually if this is necessary.
