Adco-Dapamax contains indapamide 2.5 mg, a thiazide-like diuretic. It is used for high blood pressure, and sometimes for fluid retention. It is taken once daily in the morning, long term. Like all blood pressure treatment, it manages a risk rather than a symptom.
What is Adco Dapamax?
Adco-Dapamax is registered in South Africa as Schedule 3:
| Product | Contains |
|---|---|
| Adco-Dapamax | Indapamide 2.5 mg tablet |
Indapamide is also sold as Cipla-Indapamide and other generics, and appears in combination tablets such as Triplixam. Being dispensed one rather than another is ordinary generic substitution.
Indapamide is a thiazide-like diuretic. It acts on the distal tubule of the kidney, blocking sodium reabsorption so more sodium and water leave in the urine.
But indapamide is not simply a water tablet, and this is what distinguishes it from hydrochlorothiazide:
- At the doses used for blood pressure, its diuretic effect is relatively modest. It has a direct vasodilator action — relaxing the blood vessel walls themselves — which does much of the work.
- That means blood pressure falls without a large increase in urination, which many people find easier to live with.
- It has less effect on blood sugar and cholesterol than older thiazides, which matters in people with diabetes or metabolic risk.
Like all thiazide-type diuretics, the long-term blood pressure effect is mostly vascular rather than fluid-related. In the first weeks, reduced blood volume does the work; over months, blood volume largely returns to normal while blood pressure stays down because the vessels have relaxed. That is why it keeps working after the diuretic effect fades, and why it takes a few weeks to show full benefit.
What is Adco Dapamax commonly used for?
- High blood pressure (hypertension) — the main use, usually long term.
- Fluid retention (oedema), in some cases, though loop diuretics are stronger for significant fluid overload.
- Heart failure, sometimes as part of a wider regimen.
- Reducing cardiovascular risk, since controlling blood pressure lowers the risk of stroke, heart attack, heart failure, kidney damage and vision loss.
High blood pressure has no symptoms in almost everyone who has it. This is the most important thing to understand: you will likely feel no different on Adco-Dapamax, and feeling well is not a reason to stop. It is treating a risk, not a sensation.
Thiazide-type diuretics are among the best-studied blood pressure treatments, with strong evidence for reducing strokes and heart attacks, and they are inexpensive. They are often combined with an ACE inhibitor, ARB or calcium channel blocker — combining mechanisms at moderate doses works better, with fewer side effects, than pushing one medicine to its maximum.
How Adco Dapamax fits into this medicine category
| Group | Examples | What it does |
|---|---|---|
| Thiazide-like diuretics | Indapamide (Adco-Dapamax) | Blood pressure; also relaxes vessels |
| Thiazide diuretics | Hydrochlorothiazide (Ridaq) | Blood pressure, mild fluid retention |
| Loop diuretics | Furosemide | Stronger and faster; significant oedema |
| ACE inhibitors | Enalapril, perindopril | Relax vessels; protect heart and kidneys |
| ARBs | Losartan, valsartan | Similar, without the cough |
| Calcium channel blockers | Amlodipine | Relax and widen blood vessels |
| Beta-blockers | Bisoprolol | Slow the heart, reduce its workload |

What to check before using Adco Dapamax
Take it in the morning. Taken later it may wake you at night to pass urine, though this is less pronounced than with hydrochlorothiazide.
Expect blood tests. Potassium, sodium, kidney function and sometimes uric acid and glucose are checked before starting and periodically afterwards. This is not a formality — salt imbalance is the main risk of this medicine, and it is usually silent until it is significant.
Tell your doctor or pharmacist if you:
- Have gout, or raised uric acid. Thiazide-type diuretics reduce uric acid excretion and can precipitate an attack.
- Have kidney or liver disease. Severe liver disease is a particular concern — diuretic-induced electrolyte disturbance can precipitate encephalopathy.
- Have low potassium or sodium, or are prone to them.
- Have diabetes. Indapamide affects blood sugar less than older thiazides, but monitoring is still sensible.
- Have a heart rhythm disorder, or a prolonged QT interval — low potassium raises the risk of dangerous rhythms.
- Have lupus, which can be aggravated.
- Have a sulfonamide allergy.
- Are elderly, where low sodium and dehydration are more likely.
- Are pregnant or breastfeeding.
- Take digoxin — low potassium makes digoxin toxicity more likely.
- Take lithium, whose levels rise dangerously with diuretics.
- Take anti-inflammatories such as ibuprofen. NSAIDs raise blood pressure, blunt diuretics, and combined with an ACE inhibitor or ARB can cause acute kidney injury.
- Take other medicines affecting heart rhythm, or potassium supplements.
Be careful if you become unwell with vomiting, diarrhoea or fever, or in very hot weather. Dehydration on a diuretic can affect the kidneys quickly — ask your doctor whether to pause it temporarily.
Possible cautions and when to ask a pharmacist or doctor
Common effects are dizziness when standing, tiredness, muscle cramps, headache and increased sensitivity to sunlight. Some people notice passing more urine early on, though less than with older thiazides.
Seek medical advice if you develop:
- Muscle cramps or weakness, unusual tiredness, palpitations or an irregular heartbeat — possible low potassium.
- Confusion, marked drowsiness, headache, nausea or a seizure — possible low sodium, more common in older people and in hot weather.
- A painful, hot, swollen joint, often the big toe — a gout attack.
- Marked thirst, frequent urination and blurred vision — possible raised blood sugar.
- Severe dizziness or fainting.
- Unusual or severe sunburn, or a rash on sun-exposed skin.
- A rash, blistering or peeling skin.
- Much less urine than usual.
- Fainting or palpitations, particularly if you have a rhythm disorder.
Use sun protection. Photosensitivity is a real and often overlooked effect, and thiazide-type diuretics have been associated with a small increased risk of certain skin cancers with long-term use — a reason to be sun-sensible rather than alarmed.
Stand up slowly, particularly at first, and take care with alcohol, which lowers blood pressure further.
Tell your doctor if you become pregnant, and check before starting any new medicine — especially over-the-counter anti-inflammatories.

Frequently asked questions
What is Adco-Dapamax used for? High blood pressure, and sometimes fluid retention. Each tablet contains indapamide 2.5 mg, a thiazide-like diuretic.
What is Adco-Dapamax 2.5 mg used for? 2.5 mg is the standard strength for blood pressure, taken once daily in the morning.
Is it a water tablet? It is a diuretic, but at blood pressure doses its main effect is relaxing blood vessels rather than removing large amounts of fluid — so urination increases less than with older thiazides.
How is it different from hydrochlorothiazide? Indapamide has a stronger direct vessel-relaxing effect and less impact on blood sugar and cholesterol.
When should I take it? In the morning, so any increase in urination does not disturb your sleep.
Will I feel different on it? Usually not. High blood pressure has no symptoms, so feeling no change is normal and not a sign it is not working.
Why do I need blood tests? To check potassium, sodium and kidney function. Salt imbalance is the main risk and is usually silent until significant.
Can I stop if my blood pressure is normal? No. Normal readings usually mean the medicine is working. Speak to your doctor before changing anything.
