1. What Co-Amilofruse Tablets are and what they are used for

The name of your medicine is Co-Amilofruse Tablets. Co-Amilofruse Tablets contain two different medicines called: furosemide and amiloride hydrochloride. Both belong to a group of medicines called diuretics (water tablets).

What Co-Amilofruse Tablets are used for

Co-Amilofruse Tablets can be used to stop the build up of extra water in your body. This extra water can cause swollen ankles, shortness of breath and feeling more tired than usual.

How Co-Amilofruse Tablets work

Co-Amilofruse Tablets work by helping you to pass more water (urine) than you usually do. If the extra water in your body is not removed, it can put extra strain on the heart, blood vessels, lungs, kidneys or liver.

2. What you need to know before you take Co-Amilofruse Tablets
Do not take Co-Amilofruse Tablets if:
  • You are allergic to furosemide, amiloride hydrochloride, sulphonamides (such as sulfadiazine or co-trimoxazole) or to any of the other ingredients of this medicine (listed in Section 6)

Signs of an allergic reaction include: a rash, swallowing or breathing problems, swelling of your lips, face, throat or tongue

  • You have severe problems with your kidneys
  • You have severe liver problems
  • Your doctor has told you that you have a low blood volume or are dehydrated
  • You are not passing any water (urine)
  • You have too much or too little potassium or sodium in your blood (shown in blood tests)
  • You have an illness called ‘Addison’s Disease’. This can make you feel tired and weak
  • You are breast-feeding (see “Pregnancy and breast-feeding” section below)
  • You are taking other medicines which change the amount of potassium in your blood (see “Other medicines and Co-Amilofruse Tablets” section below)
  • If the person taking the medicine is under 18 years. Co-Amilofruse Tablets are not suitable for children.

Do not take Co-Amilofruse Tablets if any of the above apply to you. If you are not sure, talk to your doctor or pharmacist before taking Co-Amilofruse Tablets.
