Indoramin works in hypertension (high blood pressure) by relaxing the blood vessels. This allows blood and oxygen to circulate more freely around the body, lowering blood pressure and reducing the strain on the heart. It is used alongside other medicines to reduce blood pressure when these medicines are not sufficient on their own.

Enlargement of the prostate gland can reduce the flow of urine from the bladder and can lead to other urinary problems. Indoramin helps to treat these symptoms by relaxing muscles around the bladder and prostate so that urine can be passed more easily.

Before taking indoramin make sure your doctor or pharmacist knows:

  • If you have liver, kidney or heart problems.
  • If you have Parkinson's disease or epilepsy.
  • If you have ever had depression.
  • If you feel dizzy or faint when standing up, or if you have ever fainted after passing urine.
  • If you are are due to have cataract eye surgery.
  • If you are pregnant, trying for a baby or breast-feeding.
  • If you have ever had an allergic reaction to this or any other medicine.
  • If you are taking any other medicines, including those available to buy without a prescription, herbal and complementary medicines.
  • Before starting this treatment, read the manufacturer's printed information leaflet from inside the pack.
  • Take indoramin exactly as your doctor has told you. It is usually taken two or three times a day.
  • It is not important whether you take indoramin before or after food.
  • Try to take indoramin 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.
  • Keep your regular appointments with your doctor 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 indoramin. This is particularly important if you are due to have cataract eye surgery.
  • Do not drink alcohol with indoramin as it can interfere with the way the medicine is absorbed by your body. Drinking alcohol will also increase feelings of sleepiness and dizziness which you may experience with indoramin.
