Lozol (Indapamide) – Patient Information

Lozol is a brand of indapamide, a medicine used to help manage high blood pressure and, in some cases, fluid retention (oedema). This page explains how Lozol works, how to take it safely, what to expect, and important precautions—written in clear, patient-friendly language for people in Australia.

Quick overview

• Active ingredient: Indapamide
• Medicine type: Diuretic (“water tablet”), belonging to the thiazide-like diuretic class
• Common uses: Hypertension (high blood pressure) and sometimes fluid retention
• How it acts: Helps your kidneys remove extra salt and water, while also relaxing blood vessels
• Typical timing: Usually taken once daily in the morning

Basic product information

Lozol contains indapamide. It is used to support blood pressure control and reduce fluid-related symptoms in appropriate patients.

Important note: Different formulations of indapamide (including modified-release versions) may exist. Always follow the specific instructions provided with your product and your healthcare professional’s advice.

How Lozol works (mechanism of action)

Indapamide is classified as a thiazide-like diuretic. It works mainly in the kidney to:

• Increase salt and water excretion by affecting how the kidney handles sodium (salt) and chloride.
• Reduce fluid volume in the bloodstream and tissues.
• Support blood vessel function: it can help relax blood vessels and improve blood flow, contributing to lower blood pressure.

Unlike some other diuretics, indapamide is often chosen for its beneficial effect on blood pressure and cardiovascular risk when used appropriately.

Pharmacokinetics (how the body handles indapamide)

Pharmacokinetics describes how a medicine is absorbed, distributed, metabolised, and eliminated.

• Absorption: Indapamide is absorbed after oral dosing. How quickly it reaches peak levels depends on the formulation (for example, modified-release preparations).
• Distribution: It circulates in the bloodstream and distributes into body tissues.
• Metabolism: Indapamide is metabolised mainly in the liver.
• Elimination: It is eliminated through urine and feces after metabolism. The active effect helps explain its once-daily use.
• Onset: Blood pressure and diuretic effects may start within hours; full benefit builds with continued daily use.

Practical implication: Because it is taken once daily, it’s important to take it consistently at the recommended time.

What it is used for (indications)

Lozol (indapamide) is used to treat:

• Hypertension (high blood pressure)
• Fluid retention (oedema) in selected situations, as determined by a clinician

In many patients, Lozol may be used alone or as part of a combination treatment plan for blood pressure control.

Dosing and timing

Typical dosing frequency

Indapamide is commonly taken once daily. Some people may be prescribed a specific dose based on their condition, age, and kidney/liver function.

When to take it

• Morning dosing is usually preferred to help reduce night-time urination.
• Take it at approximately the same time each day.

How to take it

• Swallow the tablet whole with water.
• If your product is modified-release, do not crush or chew unless specifically advised by your pharmacist or label.
• Continue taking it daily even if you feel well—high blood pressure often has no symptoms.

If you miss a dose

• Take it as soon as you remember if it’s the same day.
• If it’s close to your next dose, skip the missed dose and continue your usual schedule.
• Do not double your dose to make up for a missed tablet.

Monitoring

Your healthcare professional may arrange periodic checks, commonly including:

• Blood pressure
• Blood tests to monitor electrolytes (such as sodium and potassium) and kidney function

Food interactions and dietary considerations

Food can affect comfort and, in some cases, the absorption profile of medicines. For indapamide:

• General guidance: Lozol can usually be taken with or without food, but follow the instructions on your label and the directions given by your pharmacist.
• Salt intake: Because indapamide influences salt handling, very high-salt diets may reduce the effectiveness of blood pressure control.
• Electrolyte balance: Indapamide can alter levels of sodium and potassium. Maintaining a balanced diet (and following any dietary advice from your clinician) can help.

Tip: If you are instructed to limit fluid or follow a specific diet, continue to follow that plan.

Alcohol and medicine interactions

Alcohol

Alcohol may:

• Lower blood pressure further, potentially causing dizziness or light-headedness, especially when you stand up.
• Increase dehydration risk, which can worsen electrolyte imbalance.

Practical advice: If you drink alcohol, consider keeping intake moderate and monitor how you feel—particularly during the first days of treatment or after dose changes.

Interactions with other medicines

Indapamide may interact with other medicines, potentially affecting kidney function, electrolyte levels, or blood pressure. Tell your healthcare professional or pharmacist about all medicines you use, including non-prescription products.

Common interaction categories include:

• Other blood pressure-lowering medicines (may increase risk of low blood pressure)
• NSAIDs (e.g., ibuprofen, naproxen) can sometimes reduce the kidney-protective balance and affect diuretic effect
• Lithium (indapamide can increase lithium levels, raising toxicity risk)
• Digitalis (digoxin) and medicines that affect heart rhythm (risk may change if potassium is low)
• Medicines that can lower potassium (certain corticosteroids or laxatives may contribute)
• Medicines affected by electrolyte changes (some antiarrhythmics and other agents)

Herbal and supplement considerations: Some supplements (or “natural” products) may affect blood pressure, kidney function, or electrolytes. Check with a pharmacist if you’re unsure.

Safety profile and side effects

Like all medicines, Lozol can cause side effects. Many people tolerate indapamide well, but it’s important to know what to watch for.

Common side effects

• Increased urination (especially after starting)
• Dizziness or light-headedness, particularly when standing up
• Muscle cramps or weakness (may relate to electrolyte changes)
• Headache

Potentially serious side effects (seek urgent medical help)

Get medical advice urgently if you experience:

• Signs of severe allergic reaction: swelling of face/lips, trouble breathing, widespread rash
• Severe dizziness/fainting or symptoms of very low blood pressure
• Confusion, extreme tiredness, or worsening weakness
• Severe nausea/vomiting or inability to keep fluids down
• Very fast or irregular heartbeat, chest pain, or palpitations
• Symptoms of low sodium: severe headache, confusion, seizures (rare but serious)

Electrolyte and metabolic monitoring

Indapamide can influence:

• Potassium (low potassium can increase risk for rhythm problems and weakness)
• Sodium (low sodium may cause dizziness, confusion, or other symptoms)
• Kidney function (especially during dehydration or illness)
• Glucose and uric acid in some people (your clinician may monitor if you have diabetes or gout)

Practical use tips (what to do and what to avoid)

1) Prevent dehydration

• Drink fluids as advised by your clinician.
• Be extra cautious during hot weather, vomiting, diarrhoea, or heavy exercise.

2) Stand up slowly

If you feel dizzy when you get up, rise slowly from sitting or lying positions. This helps reduce the chance of falls.

3) Keep track of symptoms

• Note any new dizziness, cramps, unusual tiredness, or changes in urination.
• Check your blood pressure if you’ve been advised to do so.

4) Don’t stop suddenly without advice

For blood pressure, stopping abruptly may cause levels to rise again. If you’re having side effects, discuss options with your clinician or pharmacist.

5) Be careful with “double diuretics”

• Avoid taking extra diuretic-type supplements (unless specifically recommended) because they can worsen dehydration and electrolyte changes.
• Ask your pharmacist before combining products for fluid loss.

When to be extra cautious

Special caution may be needed if you have or develop:

• Kidney disease or reduced kidney function
• Liver disease
• Gout or high uric acid
• Diabetes (blood sugar monitoring may be needed)
• Heart rhythm disorders or a history of low potassium
• Dehydration, persistent vomiting, or diarrhoea
• Low blood pressure or dizziness/fainting episodes

If you become unwell (for example, with gastroenteritis), contact your healthcare professional for advice about continuing medicines.

Timing considerations: daily routine

Indapamide is usually used once per day. Many people find it easiest to:

• Take it soon after waking (unless your clinician advised otherwise)
• Keep a consistent time to maintain steady effect
• Plan bathroom access during the first days of treatment when urination increases

Travelling: Bring your tablets in your carry-on or travel bag and keep them at appropriate temperatures. Aim to take them at consistent times across time zones if possible.

Alternative options to consider

If Lozol (indapamide) isn’t suitable due to side effects, interactions, or individual health needs, other treatments may be considered. Alternatives for hypertension and fluid retention may include:

• Other thiazide or thiazide-like diuretics (some patients may respond differently)
• ACE inhibitors or ARBs (commonly used for blood pressure)
• Calcium channel blockers
• Beta-blockers (selected patients, depending on heart conditions)
• Other diuretic options if fluid retention is significant

Important: The best alternative depends on your diagnosis, kidney function, blood tests, and overall cardiovascular risk. Your pharmacist or doctor can help match options to your needs.
