Cataflam contains diclofenac 50 mg, an anti-inflammatory painkiller, supplied in South Africa as sachets and dispersible effervescent tablets. It relieves pain with an inflammatory component — period pain, migraine, dental pain, back and muscular pain, gout and arthritis — and works faster than a standard tablet.
What is Cataflam?
Cataflam contains diclofenac 50 mg, a non-steroidal anti-inflammatory drug (NSAID). It is a Schedule 3 medicine, supplied here as a sachet of powder and as a dispersible effervescent tablet.
Diclofenac blocks cyclo-oxygenase enzymes, reducing the prostaglandins that drive inflammation, swelling and pain. Those same prostaglandins protect the stomach lining and support kidney blood flow — the single fact that explains both why the medicine works and where its risks come from.
What distinguishes Cataflam from an ordinary diclofenac tablet is how fast it gets in. Cataflam uses the potassium salt of diclofenac, which dissolves readily, and both the sachet and the dispersible tablet are taken already in solution. A medicine that arrives at the stomach dissolved is absorbed considerably faster than one that has to break down first.
That matters for pain that needs relieving now — a migraine building, period pain that has started, acute dental pain — rather than for a chronic joint condition where steady levels matter more than speed. For the latter, standard diclofenac tablets or a slow-release form are the usual choice.
The speed does not change the cautions. This is the same medicine, arriving sooner.
What is Cataflam commonly used for?
Cataflam is used for pain where a rapid effect is wanted:
- Period pain, where NSAIDs are particularly effective because the cramping is prostaglandin-driven.
- Migraine attacks, where diclofenac sachets are a recognised acute treatment.
- Dental pain, including after extraction.
- Back and muscular pain.
- Sprains, strains and sports injuries.
- Gout flares.
- Arthritis, for symptom relief.
- Post-operative pain, short-term.
For period pain, the practical tip is timing: taking it as symptoms begin, rather than once the pain has established, works noticeably better. The medicine blocks prostaglandin production, and it cannot undo prostaglandins already released.
The same principle applies to migraine — treating early in an attack gives a better result than waiting to see whether it develops.
It treats the episode, not the underlying condition. Frequent migraine, or period pain severe enough to disrupt your life each month, deserves a proper assessment. There are preventive options for migraine, and endometriosis is a common and under-diagnosed cause of severe period pain. Repeatedly reaching for an anti-inflammatory is not the answer to either.
How Cataflam fits into this medicine category
| Group | Examples | Note |
|---|---|---|
| Simple analgesics | Paracetamol (Donapan) | Pain and fever; little anti-inflammatory action |
| Standard NSAIDs | Diclofenac (Cataflam, Voltaren), ibuprofen (Brufen) | Anti-inflammatory; stomach and kidney cautions |
| Potent NSAIDs | Indomethacin (Arthrexin) | Stronger; more stomach and CNS effects |
| COX-2 selective | Celecoxib (Celebrex), meloxicam | Gentler on the stomach |
| Corticosteroids | Prednisone | Far stronger anti-inflammatory, as courses |

What to check before using Cataflam
Dissolve the sachet or dispersible tablet fully in water and drink it, ideally with or after food. Use the lowest amount for the shortest period that works.
Never take another anti-inflammatory alongside it — including over-the-counter ibuprofen and combination painkillers such as Mybulen or Gen-Payne, which contain one already.
Speak to a doctor or pharmacist if:
- You have a history of stomach ulcers, bleeding, reflux or gastritis.
- You have kidney disease, or become dehydrated easily.
- You have heart disease, heart failure, high blood pressure, or have had a stroke. Diclofenac carries a recognised cardiovascular risk.
- You have asthma. A minority of people with asthma react badly to NSAIDs.
- You take blood thinners, low-dose aspirin, a corticosteroid, an SSRI antidepressant, a diuretic, an ACE inhibitor, lithium or methotrexate.
- You are pregnant. NSAIDs are generally avoided, and specifically in the third trimester.
- You are over 65, where stomach and kidney risks are higher.
- The sachet is for someone with a sodium-restricted diet — effervescent and dispersible preparations can contain significant sodium.
Follow the pack instructions. This page does not set doses.
Possible cautions and when to ask a pharmacist or doctor
Stomach. NSAIDs are the leading medicine-related cause of stomach bleeding, and ulceration can occur without preceding pain. The dissolved form is absorbed faster but is not gentler on the stomach in any meaningful sense.
Kidneys. Diclofenac can reduce kidney function, particularly in older people, when dehydrated, or on blood-pressure medicines. During an illness with vomiting or diarrhoea, or in extreme heat, use paracetamol instead unless told otherwise.
Heart. Regular use at higher amounts is associated with increased cardiovascular risk — hence the consistent advice on lowest effective amount, shortest time.
Watch the headache trap. Taking any acute painkiller for headache or migraine on most days can produce medication overuse headache, sustained by the treatment itself. More than about two days a week warrants a conversation about preventive treatment.
For localised surface pain, a diclofenac gel delivers the medicine locally with far less reaching the rest of the body.
Seek medical attention for stomach pain, vomiting blood or material resembling coffee grounds, black tarry stools, wheezing or breathlessness, chest pain, one-sided weakness or slurred speech, marked swelling of the legs or face, significantly reduced urine, or a blistering or peeling rash.

Frequently asked questions
What is Cataflam 50 mg used for? Pain with an inflammatory component where a fast effect is wanted — period pain, migraine, dental pain, back and muscular pain, gout and arthritis. It contains diclofenac.
How is it different from ordinary diclofenac? It is the same medicine in a form that dissolves and is absorbed faster. The cautions are identical.
Is it stronger than ibuprofen? Both are NSAIDs and broadly comparable in effect. People respond differently, and prescribers switch between them for tolerance rather than strength.
When should I take it for period pain? As symptoms begin rather than once the pain is established. It blocks prostaglandin production and cannot reverse what has already been released.
Can I take it with paracetamol? They are different medicines and are sometimes used together on advice. Never combine it with another anti-inflammatory.
Can I use it every month for period pain? Short courses each cycle are common, but period pain severe enough to disrupt your life warrants assessment — endometriosis is a common and under-diagnosed cause.
