Magasil is a name people encounter on a pack, generally in connection with indigestion or stomach discomfort. It does not appear in South Africa’s Medicine Price Registry, so its contents cannot be confirmed here. This guide explains how to find out what your pack contains and how stomach remedies differ.
What is Magasil?
We cannot tell you what Magasil contains, and this page will not guess.
A search of the South African Medicine Price Registry returns no product under this name. Possible explanations:
- It may be spelled differently on the actual packaging.
- The registry lists medicines with published single exit prices, so a product not currently priced may not appear.
- It may be a discontinued product, or one registered under a different name.
- It may be a general-sale or complementary product, which follow different regulatory routes.
- It may be an imported product.
A brand name is marketing, not an ingredient declaration. Names built on “mag-” are used across quite different products, and naming a likely ingredient on that basis would be irresponsible.
Read the pack. The active ingredients will be printed on it.
What is Magasil commonly used for?
Without knowing the contents, no honest page can tell you what it treats. Finding out takes minutes:
- Read the pack. Active ingredients are listed on the side or back panel.
- Look for a registration number, often formatted like
28/2.7/0019. - Take the pack to a pharmacist — free, quick, and the most reliable option.
- Search the Medicine Price Registry using the exact spelling on the pack.
- Ask whoever supplied it.
If it turns out to be a stomach remedy, the type matters a great deal, because they work differently and are not interchangeable:
| Type | Examples | How it works | Onset |
|---|---|---|---|
| Antacids | Aluminium and magnesium salts | Neutralise acid already present | Minutes; brief |
| Alginates | Gaviscon-type products | Form a raft to block reflux | Minutes |
| H2 blockers | Cimetidine, famotidine | Reduce acid production | About an hour |
| Proton pump inhibitors | Omeprazole | Strongly reduce acid production | A day or more |
| Antispasmodics | Hyoscine | Relieve gut cramping, not acid | Under an hour |
| Adsorbents | Kaolin, charcoal | Bind gut contents | Variable |
Something that eases heartburn will do nothing for cramping, and an antispasmodic will not settle acid reflux. Matching the medicine to the actual problem is the whole point.
A general point about magnesium- and aluminium-containing antacids, since they are so common: aluminium tends to constipate and magnesium tends to loosen, which is why products often combine them. Both depend on kidney function to be cleared, which is why kidney disease is a specific caution with antacids — magnesium can accumulate to harmful levels when the kidneys cannot excrete it.
How Magasil fits into this medicine category
This page sits in general medicines, a category covering products that do not fall neatly elsewhere. Once you have identified the ingredient, look that up directly. See the general medicines hub, the HP553 guide and the K-Fenak OTC guide.
One point applies whatever the product turns out to be. If you need something for indigestion or heartburn on most days, that is worth a conversation with a doctor rather than an ongoing supply. Persistent reflux has treatments that address it properly, and persistent symptoms occasionally reflect something that needs finding.
What to check before using Magasil
Whatever the product turns out to be:
- Identify the active ingredients before taking it.
- Check timing instructions. Stomach medicines are unusually timing-sensitive — some work best before food, some after.
- Separate it from other medicines by at least two hours if it is an antacid. Antacids reduce absorption of many medicines, including some antibiotics, thyroid medicine and iron — a common and easily missed cause of treatment failure.
- Check the sodium content, if you have high blood pressure, heart failure or are on a salt-restricted diet. Some antacids contain meaningful amounts.
- Check the expiry date, and that packaging is intact and unopened.
- Be cautious with anything sold loose, unlabelled or repackaged.
- Ask specifically if you have kidney disease, are pregnant or breastfeeding, or are giving it to a child or an elderly person.
Do not take an unidentified product alongside prescription medicines without checking first.
Possible cautions and when to ask a pharmacist or doctor
Because the ingredient is unknown, specific cautions cannot be given. General points:
Seek medical attention urgently for signs of a serious allergic reaction to any medicine: swelling of the face, lips, tongue or throat, difficulty breathing or swallowing, a widespread rash, or feeling faint.
Some stomach symptoms need assessment rather than self-treatment. See a doctor promptly for:
- Vomiting blood, or vomit resembling coffee grounds.
- Black, tarry stools, or visible blood in the stool.
- Difficulty or pain on swallowing, or food sticking.
- Unintended weight loss.
- Persistent vomiting, or inability to keep fluids down.
- Severe or worsening abdominal pain, or a rigid, tender abdomen.
- A first episode of significant indigestion over the age of 55.
- Anaemia, or being told your iron is low.
- Symptoms lasting more than two weeks, or returning whenever treatment stops.
Chest pain is not always indigestion. Pain with breathlessness, sweating, or pain spreading to the arm or jaw needs emergency assessment, not an antacid. This confusion is common and occasionally fatal — a heart attack is frequently described by the person having it as bad indigestion.
If a product is not helping after a few days, that is information. Either it is the wrong medicine for the problem, or the problem needs diagnosing. Continuing an unidentified product in the hope it eventually works is the least useful option.

Frequently asked questions
What is Magasil medicine used for? We cannot say. No product under this name appears in South Africa’s Medicine Price Registry, so its ingredients are not established. Read the pack or ask a pharmacist.
Why does this page not name the ingredients? Because guessing would be unsafe. Stomach medicines work in entirely different ways, with different timing, cautions and interactions.
Is it an antacid? People commonly ask about it in that context, but a brand name is not an ingredient declaration. Confirm from your pack.
How do I find out what my pack contains? Read the active ingredient list on the label, and take the pack to a pharmacist. Identification is free and quick.
Is it still available? Its absence from the registry may mean it is discontinued, no longer priced, or listed under a different spelling. A pharmacist can tell you.
Can I take it with my other medicines? Not until you know what it contains. If it is an antacid, it may reduce absorption of several medicines — separate them by at least two hours.
Is it safe with kidney disease? Ask a doctor. Magnesium- and aluminium-containing antacids depend on the kidneys to be cleared, and magnesium can accumulate when they cannot.
When should I see a doctor instead? For vomiting blood, black stools, difficulty swallowing, unintended weight loss, severe pain, or a first episode of significant indigestion over 55.
