Adco-Mayogel is an antacid suspension from Adcock Ingram, taken for heartburn, indigestion and acid reflux. It is not a painkiller despite where this page sits — and no product under this exact name appears on the South African Medicine Price Registry, so check your own bottle for its ingredients.
What is Adco Mayogel?
No product called Adco-Mayogel appears on the South African Medicine Price Registry. Searching for it returns other Adcock Ingram products matched on the “Adco” prefix alone — Adco-Diclofenac, Adco-Ibuprofen, Adco-Contromet, Adco-Loperamide and others. None of those is this product, and their ingredients tell you nothing about it. Disregard them if you search the register yourself.
What Mayogel is. Products sold under this name in South Africa are antacid suspensions — the familiar white, chalky liquid taken by the spoonful for heartburn. Antacids of this type are built on aluminium hydroxide and magnesium hydroxide or trisilicate, sometimes with simethicone for wind.
Because the registry does not confirm the formulation, this page does not assert what is in your bottle. Read the label. The active ingredients are printed on it, usually in small type, and a pharmacist can confirm in seconds.
How antacids work. They are alkalis that chemically neutralise acid already in the stomach. The reaction is immediate, which is why relief comes within minutes — and it is also why the effect is short-lived, lasting perhaps an hour or two until more acid is produced.
This is the key distinction from every other acid medicine. Antacids neutralise acid that is already there. Proton pump inhibitors and H2 blockers reduce the acid being made — slower to act, but lasting far longer. They do different jobs, and for many people the sensible arrangement is a PPI daily plus an antacid for breakthrough symptoms.
The two mineral components balance each other. Aluminium salts constipate; magnesium salts loosen. Combining them keeps the bowels roughly neutral — which is why almost every antacid contains both rather than one alone.
A note on placement: an antacid is a digestive medicine, not a painkiller. This page’s category is being corrected.
What is Adco Mayogel commonly used for?
- Heartburn — the burning behind the breastbone, particularly after meals or when lying down.
- Acid indigestion and dyspepsia.
- Acid reflux, for immediate symptom relief.
- Trapped wind and bloating, if the product contains simethicone.
- Settling an upset stomach after rich or spicy food.
- Breakthrough symptoms while a proton pump inhibitor is taking effect, which takes a day or two.
- Heartburn in pregnancy, where antacids are generally among the first options — though confirm the specific product, since some are unsuitable.
Antacids are for occasional relief, not ongoing management. If you need one most days for more than a couple of weeks, the underlying problem needs addressing rather than repeatedly neutralising.
The lifestyle measures genuinely work, and are worth doing before escalating medication: smaller meals, not lying down within three hours of eating, raising the head of the bed, losing excess weight, and cutting back alcohol, smoking, and personal trigger foods such as coffee, chocolate, tomato and anything fatty or spicy.
A practical point about timing. Antacids work best taken when symptoms occur, or about an hour after a meal — when acid production has peaked and there is food to buffer. Taken on an empty stomach they are neutralised and cleared quickly.
How Adco Mayogel fits into this medicine category
Its actual relatives are the acid medicines, not the analgesics:
| Group | Examples | How it works |
|---|---|---|
| Antacids | Mayogel-type suspensions, Gaviscon, Rennies | Neutralise acid present; act in minutes |
| Alginates | Gaviscon | Form a raft over stomach contents |
| H2 blockers | Famotidine, cimetidine | Reduce acid production; moderate, fast |
| Proton pump inhibitors | Pantoprazole, omeprazole, esomeprazole | Strongest acid suppression; slow onset |
| Antispasmodics | Hyoscine | Cramping, not acid |
| Anti-nausea | Metoclopramide | Nausea and stomach emptying |

What to check before using Adco Mayogel
Read the label for the active ingredients, since the registry does not confirm them. Then speak to a pharmacist or doctor if you:
- Have kidney disease. This is the most important check with any aluminium- or magnesium-containing antacid — impaired kidneys cannot clear these minerals, and they accumulate.
- Are on a low-sodium diet, or have high blood pressure or heart failure. Some antacids carry a significant sodium load.
- Have liver disease.
- Are elderly, where constipation and mineral accumulation are more likely.
- Are pregnant or breastfeeding.
- Are giving it to a child.
The interaction that catches most people: antacids bind other medicines in the stomach and stop them being absorbed. Separate by at least two hours from:
- Thyroid medicine (levothyroxine) — clinically important.
- Iron supplements.
- Tetracycline and quinolone antibiotics — doxycycline, ciprofloxacin.
- Bisphosphonates for osteoporosis.
- HIV medicines, particularly integrase inhibitors such as dolutegravir.
- Some antifungals, digoxin, and phenytoin.
Practical points:
- Shake the bottle well before each dose.
- Follow the label for how much and how often, and the daily maximum. This page does not set doses.
- Take it when symptoms occur or an hour after eating.
- Use it for a few days at a time, not indefinitely.
- Do not use it to push on through persistent symptoms — that is how a real problem gets masked.
Possible cautions and when to ask a pharmacist or doctor
Antacids are generally well tolerated. Common effects are constipation (aluminium), diarrhoea (magnesium), chalky taste, nausea and bloating. The balance between the two minerals usually keeps bowel effects mild.
Do not treat alarm symptoms with an antacid. See a doctor promptly rather than self-treating if you have:
- Difficulty or pain swallowing.
- Unintentional weight loss.
- Persistent vomiting.
- Vomiting blood, or black tarry stools.
- Anaemia, or unexplained tiredness.
- New indigestion over the age of 45 to 50.
Get emergency help for:
- Severe chest pain, particularly with breathlessness, sweating, nausea, or pain spreading to the arm, neck or jaw, or coming on with exertion. Reflux and cardiac pain feel similar, and an antacid is not a test — people have died taking one for a heart attack.
- Vomiting blood or black tarry stools.
- Swelling of the face, lips or tongue, or difficulty breathing.
Seek prompt advice for:
- Persistent constipation or diarrhoea from regular use.
- Muscle weakness, unusual tiredness, confusion or bone pain, particularly with kidney disease — possible mineral accumulation.
- Symptoms not settling within a couple of weeks, or returning as soon as you stop.
- Needing an antacid most days.
Contact your doctor if heartburn is frequent enough to need daily treatment. Frequent reflux is a treatable condition rather than a fact of life, and a proton pump inhibitor course plus the lifestyle measures resolves it for most people — considerably better than neutralising acid several times a day indefinitely.

Frequently asked questions
What is Adco-Mayogel used for? Heartburn, acid indigestion and reflux. It is an antacid suspension that neutralises stomach acid. No product under this exact name appears on the medicine price registry, so check your bottle for its ingredients.
Is it a painkiller? No, despite this page’s category. It is an antacid for stomach acid.
How quickly does it work? Within minutes — antacids neutralise acid already present. The effect lasts an hour or two.
How is it different from omeprazole or pantoprazole? Those reduce the acid being made, taking a day or two to work but lasting around 24 hours. An antacid neutralises acid already there, working immediately but briefly.
When should I take it? When symptoms occur, or about an hour after a meal. On an empty stomach it is cleared quickly.
Can I take it with my other medicines? Separate it by at least two hours from thyroid medicine, iron, bisphosphonates, and tetracycline or quinolone antibiotics — antacids bind them and stop them working.
Can I use it every day? Not indefinitely. Needing an antacid most days for more than a couple of weeks means the underlying reflux should be treated properly.
Is it safe in pregnancy? Antacids are generally among the first options for heartburn in pregnancy, but confirm the specific product with a pharmacist.
Why does the medicine register show other Adco products? Because the search matches the “Adco” manufacturer prefix. Those are unrelated products — disregard them.
