Lacidipine is used to treat hypertension (high blood pressure). People with high blood pressure often do not feel unwell but, if left untreated, high blood pressure can harm your heart and damage blood vessels, leading to a heart attack or stroke.

Lacidipine works by relaxing (widening) your blood vessels. This lowers your blood pressure and allows blood to circulate more freely around your body.

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking lacidipine it is important that your doctor or pharmacist knows:

  • If you are pregnant, trying for a baby or breast-feeding.
  • If you have liver problems.
  • If you have any heart problems or angina (chest pain), or if you have recently had a heart attack.
  • If you have porphyria (this is a rare inherited blood disorder).
  • If you are taking or using any other medicines. This includes any medicines you are taking which are available to buy without a prescription, such as herbal and complementary medicines.
  • If you have ever had an allergic reaction to a medicine.
  • Before you start taking these tablets, read the manufacturer's printed information leaflet from inside the pack. The leaflet will give you more information about lacidipine and a full list of side-effects which you may experience from taking it.
  • Take lacidipine exactly as your doctor has told you to. The usual starting dose is 2 mg daily (one tablet), taken preferably in the morning. This is likely to be increased after a few weeks to 4 mg daily. It may then be increased further, to 6 mg daily. Lacidipine is available in two strengths of tablet - 2 mg and 4 mg. Your dose and the strength of your tablets will be on the label of the pack to remind you.
  • Take the tablets with a drink of water. You can take them before or after your meals.
  • Try to take your doses at the same time of day, each day. This will help you to remember to take them.
  • Do not drink grapefruit juice while you are on lacidipine. This is because a chemical in grapefruit juice increases the amount of lacidipine in your bloodstream and 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.
  • Try to keep your regular appointments with your doctor. This is so your doctor can check on your progress.
  • If you drink alcohol, ask your doctor for advice. Your doctor may recommend that you do not drink alcohol while you are on this medicine. It will increase the chance that you experience side-effects such as feeling dizzy and light-headed.
  • If you buy any medicines, check with a pharmacist that they are suitable for you to take. This is because some medicines may interfere with lacidipine and may not be recommended for you.
  • If you are having an operation or dental treatment, tell the person carrying out the treatment that you are taking lacidipine.
  • Treatment with lacidipine is usually long-term unless you experience an adverse effect. Continue to take the tablets unless you are advised otherwise. If it is necessary for you to stop taking it, your doctor may want you to reduce your dose gradually over a few days, as stopping taking lacidipine suddenly may cause problems.

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. These usually improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following side-effects continue or become troublesome.
