Soflax is a name people encounter on a pack, but it does not appear in South Africa’s Medicine Price Registry as a registered medicine. This guide explains what that means, how to establish what your pack contains, and — since the name suggests a laxative — how constipation treatments differ and when constipation needs a doctor.
What is Soflax?
We cannot tell you what Soflax contains, and this page will not guess.
A search of the South African Medicine Price Registry — the authoritative database of SAHPRA-registered medicines, listing active ingredients, strengths and schedules — returns no product under this name.
Possible explanations:
- It may be a complementary or general-sale product, which follows a different regulatory route.
- It may be spelled differently on the actual packaging.
- It may be an imported product not registered in South Africa.
- It may be a discontinued or regional product.
The name is suggestive but not evidence. “-lax” commonly appears in laxative brand names, and “sof-” hints at stool softening — but brand names are marketing, not ingredient declarations, and acting on a guess about a medicine is exactly the wrong approach. Read the pack.
What is Soflax commonly used for?
Without knowing what the product contains, no honest page can tell you what it treats. Here is how to find out, quickly:
- Read the pack. Active ingredients are listed on the side or back panel. This single step answers most questions.
- Look for a registration number, often formatted like
28/2.7/0019, or a complementary medicine designation. - Take the pack to a pharmacist — the most reliable option, and free.
- Search the Medicine Price Registry using the exact spelling on the pack.
- Ask whoever supplied it.
Do not take a medicine you cannot identify, particularly alongside other medicines, during pregnancy or breastfeeding, or when giving it to a child.
If it does turn out to be a laxative, the type matters a great deal, because they work differently and suit different situations:
| Type | Examples | How it works | Onset |
|---|---|---|---|
| Bulk-forming | Ispaghula, psyllium | Adds bulk and water | 2–3 days |
| Osmotic | Lactulose, macrogol | Draws water into the bowel | 1–3 days |
| Stool softeners | Docusate, liquid paraffin | Softens hard stool | 1–3 days |
| Stimulant | Senna, bisacodyl | Stimulates bowel contractions | 6–12 hours |
| Suppositories/enemas | Glycerine, phosphate | Acts locally | Minutes to an hour |
Bulk-forming and osmotic laxatives are generally preferred for regular use. Stimulant laxatives are effective but are meant for short courses — prolonged daily use is best avoided without advice.
Drink plenty of water with any laxative, especially bulk-forming ones, which can worsen the problem if taken with too little fluid.
How Soflax 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 it up directly.
| Group | Examples | Used for |
|---|---|---|
| Laxatives | Lactulose, senna, docusate | Constipation |
| Anti-diarrhoeals | Loperamide | Diarrhoea |
| Antacids and acid reducers | Lansoprazole | Heartburn, reflux, ulcers |
| Antispasmodics | Hyoscine | Cramping and colicky pain |
| Analgesics | Paracetamol, NSAIDs | Pain |
See the general medicines hub and the HP553 guide for other pages in this category.
What to check before using Soflax
Whatever it turns out to be:
- Identify the active ingredients before taking it.
- Check it against everything else you take, including supplements and traditional remedies.
- Check the expiry date, and that packaging is intact and unopened.
- Be cautious with anything sold loose, unlabelled or repackaged.
- Ask specifically if you are pregnant or breastfeeding, have liver or kidney disease, heart disease or diabetes, or are giving it to a child or elderly person.
If it is a laxative, additional points apply:
- Do not use a stimulant laxative every day long-term without medical advice.
- Do not use any laxative if you have severe abdominal pain, a swollen abdomen, or are vomiting — these can indicate an obstruction, where a laxative may be harmful.
- Increase fluid and fibre alongside it. Laxatives address the symptom; diet, fluid and activity address the cause.
- Check for hidden laxatives in “detox”, “slimming” or “cleansing” teas and supplements, which frequently contain senna and can be taken unknowingly for long periods.
- Do not give laxatives to children without medical advice.
Possible cautions and when to ask a pharmacist or doctor
Stop and seek advice if you develop a rash, swelling of the face or lips, difficulty breathing, or symptoms that worsen after starting any product.
Constipation is usually harmless, but some patterns need assessment rather than self-treatment. See a doctor promptly if you have:
- Blood in the stool, or black, tarry stools.
- A persistent change in bowel habit lasting more than a few weeks, particularly over the age of 45.
- Unintended weight loss.
- Severe or worsening abdominal pain, or a swollen, tender abdomen.
- Vomiting, or inability to pass wind as well as stool — possible obstruction, needing urgent attention.
- Constipation alternating with diarrhoea.
- Anaemia, or being told your iron is low.
- A family history of bowel cancer or inflammatory bowel disease.
- Constipation that began after starting a new medicine — opioids, iron, some antidepressants and some blood pressure medicines are common causes, and this is often solvable.
- New constipation with no obvious explanation, especially with fatigue or other symptoms.
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 — a pharmacist can usually resolve it in minutes.

Frequently asked questions
What are Soflax tablets 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.
Is Soflax a laxative? The name resembles laxative brand names, but a brand name is not an ingredient declaration. Check the active ingredients on your pack rather than assuming.
Why does this page not name the ingredients? Because guessing would be unsafe. Medicines that sound similar can work in entirely different ways and carry different cautions.
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 a registered medicine? It does not appear in the medicine registry under this name. It may be a complementary or general-sale product, or registered under a different spelling.
Can I take it with my other medicines? Not until you know what it contains. Interactions are the most common avoidable harm from unidentified products.
How long can I use a laxative? Bulk-forming and osmotic laxatives can be used longer term on advice. Stimulant laxatives are for short courses — daily long-term use needs medical guidance.
When should I see a doctor about constipation? For blood in the stool, unintended weight loss, a persistent change in bowel habit, severe pain, or vomiting with inability to pass wind.
