Moduretic Cost and Purchase Channels - in Australia

Overview of on topic and makeup

Moduretic is a fixed dose tablet combining two active components: amiloride and hydrochlorothiazide. A common formulation is 5 mg amiloride with 50 mg hydrochlorothiazide (often written as 5/50 mg).

Hydrochlorothiazide is a thiazide diuretic that increases sodium and water excretion by the kidneys, lowering blood volume and blood pressure. Amiloride is a potassium-sparing diuretic that counteracts excessive potassium loss caused by the thiazide part of the combination.

Typical uses include reduction of oedema and treatment of hypertension. Clinicians may choose this combination when they want diuresis without large falls in serum potassium.

Core safety advisories

Do not take Moduretic unless prescribed by a clinician and you have discussed the following conditions with them.

• Known hyperkalaemia (high blood potassium)
• Severe kidney disease or if you are unable to pass urine
• Hypersensitivity to amiloride, hydrochlorothiazide, or related sulfonamide medicines
• Concomitant use of potassium supplements or potassium-based salt substitutes without medical approval

Tell your prescriber if you have any history of the following as they may affect safety or supervision and monitoring:

• Cardiac problems, including recent myocardial infarction
• Liver disease such as cirrhosis
• Respiratory conditions including severe asthma or COPD
• Gout or elevated uric acid
• Autoimmune diseases including systemic lupus erythematosus
• Diabetes mellitus, the sugar disease mellitus, referred to as DM
• Pancreatic disorders
• Current use of corticosteroids or other blood pressure medicines

Avoid overheating and do not let yourself become dehydrated. Both excessive fluid loss and extreme fluid restriction can be harmful while taking this medicine.

Before you start up

Prepare a full list of all prescription medicines, over-the-counter remedies and herbal products you use and share this with your prescriber and pharmacist. Moduretic can interact with many substances.

If you are booked for blood tests, mention you take a thiazide diuretic because it can affect electrolyte results and some endocrine assays.

Moduretic usage guidelines

• Follow the directions on the prescription label; do not stop or change your dose without talking to your prescriber.
• Take the tablet with food and a full glass of water unless your prescriber advises differently.
• Regular time sensitive monitoring is common. Expect periodic checks of blood pressure, kidney function and serum electrolytes, with particular attention to potassium.
• If you develop persistent vomiting or severe diarrhoea, seek medical advice as dehydration may require dose adjustment or temporary cessation.
• Notify any treating surgeon, anaesthetist or dentist that you take amiloride/hydrochlorothiazide; short-term suspension may be recommended in some procedures.
• Keep tablets at room temperature, out of direct heat and moisture. Do not put them in the refrigerator or freezer.

Blood pressure benefits may not produce obvious symptoms. Continue treatment even if you feel well, unless instructed to stop.

Dose omission vs overdose incident

Missed the dose

When one dose is missed, take it as soon as you can remember it, unless the next dose is due soon. In that case skip the i did not take my prescribed dose; do not double up to compensate.

Overdosing

If an suspected overdose is suspected, get emergency care immediately or contact a poison information service. Symptoms of suspected overdose may include severe dizziness, fainting, very slow or irregular heartbeat, confusion, extreme thirst, or markedly reduced urine output.

Hazard prevention tips and items to avoid

• Avoid heavy alcohol consumption; it can worsen dizziness or light-headedness associated with blood pressure reductions.
• Use caution with other medicines that cause sedation or impair coordination; check with your prescriber before combining them.
• Do not use potassium-containing salt substitutes unless approved by your doctor because potassium may rise excessively.
• Both very high and very low dietary salt intake can affect how the medicine works; follow dietary advice tailored to you.

Until you know how Moduretic affects you, be careful when driving or operating machinery.

Potential systemic drug side effects

Obtain immediate medical care for numbness or weakness signs of a serious allergic reaction such as hives, swelling of the face or throat, or breathing difficulty.

Signs that require immediate medical review

• Marked heart rhythm changes: very slow, very fast, or irregular heartbeat
• Severe muscle weakness, cramps, numbness or tingling
• Pronounced lethargy, ongoing dizziness, or confusion
• Noticeably reduced urine output
• Severe thirst with dry mouth, ongoing vomiting or nausea
• Breathing difficulty, tremor, or mental clouding
• Possible liver injury signs: abdominal pain, fever, loss of appetite, dark urine, pale stools, or jaundice

Everyday mild reactions

• Mild gastrointestinal upset such as nausea or bloating
• Occasional vomiting
• Rashes or mild skin reactions

Look for medication mutual interaction considerations

Always inform your prescriber if you are taking any of the following, as they may interact with amiloride/hydrochlorothiazide:

• ACE inhibitors (for example lisinopril, enalapril, ramipril)
• Angiotensin receptor blockers (for example losartan, candesartan, valsartan)
• Non-steroidal anti-inflammatory drugs including ibuprofen, naproxen and indomethacin
• Calcineurin inhibitors such as cyclosporine or tacrolimus
• Lithium
• Cardiac glycosides like digoxin
• Anticoagulant agents that include warfarin
• Insulin and many oral glucose-lowering agents
• Corticosteroids given systemically

The list is not complete. Vitamins, herbal remedies and other prescription or non-prescription medicines may also interact. Confirm with your doctor or pharmacist before starting or stopping any product.

Other options plus analogous medicines

Depending on the clinical situation, a prescriber may select one of several substitute options to Moduretic:

• Single thiazide or thiazide-like diuretics: hydrochlorothiazide, indapamide, chlorthalidone
• Other potassium-sparing agents: spironolactone or eplerenone, often used for resistant hypertension or to conserve potassium
• Loop diuretics for more potent fluid removal: furosemide or bumetanide
• Combinations pairing a thiazide with an ACE inhibitor or an ARB
• Other antihypertensive classes: ACE inhibitors, ARBs, calcium channel blockers, or beta blockers when diuretics are not appropriate

Price and status monitoring requirements differ between options. Discuss pros and cons, including side effect profiles and status monitoring needs, as advised by your prescriber.

Rough price ranking and comparison in AUD for commonly available options:

• Generic hydrochlorothiazide or similar thiazides: around AUD 6 to AUD 25 per month depending on pack size and PBS status.
• Amiloride/hydrochlorothiazide combination when purchased privately: often around AUD 12 to AUD 45 for a 30-tablet supply.
• Spironolactone: frequently inexpensive (about AUD 10 to AUD 30), while eplerenone can be pricier unless subsidised (around AUD 30 to AUD 60 or more).
• Loop diuretics such as furosemide: typically low cost but may need closer time sensitive monitoring and different dosing schedules.

Actual costs will vary with brand, pharmacy, and whether PBS subsidies apply. Talk to your pharmacist for current prices and any available substitutions.
