1 What Co-amilozide is and what it is used for
Co-amilozide Tablets contain a combination of Amiloride and Hydrochlorothiazide (HCT).
Hydrochlorothiazide (HCT) is one of a group of medicines known as thiazide diuretics. These work by increasing the volume of urine you produce, therefore reducing the water content of your blood and in turn the volume of blood circulating in your body. Hydrochlorothiazide can cause potassium to be filtered out of the blood, which can sometimes cause the level of potassium in the blood to fall too low.
Amiloride is one of a group of medicines known as potassium-sparing diuretics. Amiloride is a weaker diuretic that causes potassium to be retained in the body. It is used in combination with the Hydrochlorothiazide in this medicine to prevent the amount of potassium in the blood from falling too low.
Amiloride + Hydrochlorothiazide Tablets (referred to as Co-amilozide throughout this leaflet) are used for the treatment of high blood pressure (hypertension), heart failure & fluid retention.
2 What you need to know before you take Co-amilozide

• If you have high levels of potassium in the blood [hyperkalaemia] (especially if you are elderly, diabetic or suffer from liver or heart failure), are currently taking potassium-sparing diuretics such as spironolactone or triamterene (see “Other medicines and Co-amilozide”), potassium supplements or potassium-rich foods (unless you have severely low levels of potassium and you are being carefully monitored)
• You suffer from kidney failure, kidney disease or other kidney problems such as anuria (failure of the kidneys to produce urine)
• You suffer from sever liver failure or severe liver disease (hepatic cirrhosis)
• You suffer from Addison's disease

Warnings and precautions
Talk to your doctor before taking Co-amilozide:
• If you are diabetic. The status of kidney function should be determined before Co-amilozide is given to known or suspected diabetics. Co-amilozide should be discontinued for at least 3 days before giving an intravenous (via a tube inserted into one of your veins) glucose-tolerance test as HCT may impair the results. Diabetes may be caused or aggravated by treatment with Co-amilozide. Dosage adjustment of anti-diabetic medicines, including insulin, may be required (see “Other medicines and Co-amilozide”)
• If you suffer from or have previously suffered from increased acidity in the blood (acidosis)

o Low blood levels of sodium which can cause tiredness and confusion, muscle twitching, fits and coma (hyponatraemia) o Abnormally high alkalinity of the blood and body fluids (hypochloraemic alkalosis) o Abnormally low levels of potassium in the blood (hypokalaemia)
o An abnormally low level of magnesium in the blood (hypomagnesaemia)
• If you are being severely sick (vomiting)
• If you are receiving fluids intravenously (via a tube inserted into one of your veins)
• If you suffer from Systemic Lupus Erythematosus (long-term inflammation of skin)

Co-amilozide and alcohol
During treatment with Co-amilozide, it is advisable not to drink alcohol as this may cause you to become dizzy or faint on standing up from a resting position.
Pregnancy and breast-feeding Pregnancy
You must tell your doctor if you are pregnant or if you think that you are. Usually, your doctor will advise you to take another medicine instead of Co-amilozide, as Co-amilozide is not recommended during pregnancy. This is because Co-amilozide crosses the placenta and its use after the third month of pregnancy may cause potentially harmful foetal and neonatal effects.
Breastfeeding
Tell your doctor if you are breast-feeding or about to start breast-feeding. Co-amilozide is not recommended for mothers who are breast-feeding.
Driving and using machines
Although rare, you may feel weak, tired, dizzy, dazed or experience a feeling of “spinning” (vertigo), whilst taking this medicine. If any of these symptoms are experienced, it may be necessary to avoid driving or operating machinery or pursuing any activity in which full attention is required.
Co-amilozide contains lactose
If you have been told by your doctor that you have intolerance to some sugars, contact your doctor before taking this medicine.
