Why do you need to take these tablets?

Your doctor has prescribed Moducren for you because you have high blood pressure. Although you may not feel unwell, high blood pressure can increase your risk of heart disease or stroke, if left untreated.

Are there patients who should not take these tablets?

Yes; do not take the tablets if:

  1. You are or think you may be pregnant.
  2. You are planning to become pregnant.
  3. You are breast-feeding.
  4. You have asthma or other lung disease, such as bronchitis or emphysema.
  5. You have a problem with your heart, such as heart failure.
  6. You have a high level of a naturally occurring chemical called potassium in your blood; or you are currently taking medicines which make your body retain this chemical, such as potassium supplements or some types of water tablets. Your doctor will know which medicines these are.
  7. You have kidney or liver problems.
  8. You are a diabetic or have been diagnosed as subject to spontaneous hypoglycaemia.
  9. You are allergic to any of the ingredients.
  10. You are allergic to any sulphonamide-derived drugs. (Ask your doctor if you are not sure which ones these are.)

If you think any of these apply to you, do not take the tablets, go and talk to your doctor first and follow his advice.
