1. What Amiloride Tablets are and what they are used for

The name of your medicine is Amiloride 5mg Tablets. It contains amiloride hydrochloride. This belongs to a group of medicines called diuretics (water tablets).

Amiloride can be used to stop the build up of extra water in your body. It does this without loss of potassium from your body. This extra water can lead to high blood pressure, heart problems (congestive heart failure) and liver problems (hepatic cirrhosis).

It works by helping you to pass more water (urine) than you usually do.

2. Before you take Amiloride Tablets
Do not take Amiloride Tablets and tell your doctor if:
  • You are allergic (hypersensitive) to amiloride or any other ingredients in this medicine (listed in Section 6 below). Signs of an allergic reaction include: a rash, itching or shortness of breath
  • You have kidney problems
  • Your doctor has told you that you have high potassium levels or you are taking other potassium conserving drugs or potassium supplements
  • The person taking the medicine is a child under 18 years old.

Do not take this medicine if any of the above apply to you. If you are not sure, talk to your doctor before taking Amiloride Tablets.

Take special care with Amiloride Tablets

Before you take Amiloride Tablets tell your doctor if:

  • You are elderly or seriously ill
  • You have diabetes
  • You have liver problems
  • Your doctor has told you that you have too much acid in your blood. This can be caused by diabetes or heart or lung disease.

If you are not sure if any of the above apply to you, talk to your doctor or pharmacist before taking Amiloride Tablets.


Tell your doctor or nurse you are taking Amiloride Tablets if you are going to have a glucose tolerance test. This is because this medicine can affect the results. You will need to stop taking this medicine three days before your test.

Taking other medicines

Please tell your doctor of pharmacist if you are taking or have recently taken any other medicines.

This includes medicines you buy without a prescription, including herbal medicines. This is because Amiloride Tablets can affect the way some other medicines work. Also, some medicines can affect the way Amiloride Tablets work.

In particular, tell your doctor if you are taking any of the following:

  • Lithium - used for depression
  • Medicines used to treat high blood pressure including ACE inhibitors, angiotensin-II antagonists, alpha-blockers, beta-blockers, calcium channel blockers and hydralazine

  • General anaesthetics, used to stop pain during surgery
  • Non-steroidal anti-inflammatory (NSAID) medicines such as indometacin, diclofenac and ibuprofen. Your doctor may want to carry out tests on your kidneys and the level of potassium in your blood, especially if you are an older person
  • Chlorpropramide - used to treat diabetes
  • Carbamazepine - used for epilepsy
  • Levodopa – used to treat Parkinson’s disease
  • Medicines used to treat depression including tricyclic antidepressants (such as amitriptyline) and monoamine oxidase inhibitors (MAOIs – such as phenelzine)
  • Phenothiazines – used to treat mental illness
  • Medicines used to treat inflammation (such as cortisone and hydrocortisone)
  • Tizanidine or baclofen – used to relax muscles
  • Carbenoxolone – used to treat stomach ulcers
  • Some oral contraceptives (the pill) or oestrogen (female sex hormone) preparations
  • Alprostadil – used to treat male impotence and for heart defects in infants.

This medicine does not cause loss of potassium from your body as other water tablets do.

Therefore, it is not necessary for you to get extra potassium in your diet or take supplements. Too much potassium could even be harmful.
