Disprin is aspirin. In South Africa the name covers two quite different products: Disprin Plus 10, an aspirin 500 mg tablet for pain and fever, and Disprin Cardiocare, an effervescent aspirin 100 mg tablet taken daily to reduce the risk of heart attack and stroke. Confusing the two matters.
What is Disprin?
The South African Medicine Price Registry lists three Disprin entries, all Schedule 2 (available from a pharmacy without a prescription):
| Product | Form | Strength |
|---|---|---|
| Disprin Plus 10 (formerly Codis 10) | Tablet | Aspirin 500 mg |
| Disprin Cardiocare | Effervescent tablet | Aspirin 100 mg |
Aspirin — acetylsalicylic acid — is one of the oldest medicines in continuous use, and one of the few that does genuinely different jobs at different doses.
At 500 mg, aspirin is a painkiller, an anti-inflammatory and a fever reducer, working like other NSAIDs by blocking the enzymes that produce prostaglandins.
At 100 mg, it does something else. It permanently disables an enzyme in platelets, the cells that start blood clots. Because platelets cannot repair the damage, one small daily dose keeps them less sticky for their whole lifespan of about ten days. That is why the low dose is used to prevent heart attacks and strokes, and why it does very little for a headache.
A high-dose tablet is not a substitute for the low-dose one, and vice versa. If you have been prescribed daily low-dose aspirin, take the 100 mg product, not the 500 mg one.
What is Disprin commonly used for?
Disprin Plus 10 (aspirin 500 mg) is used for:
- Headache, including tension headache.
- Toothache and period pain.
- Muscular aches, backache and joint pain, where the anti-inflammatory effect helps.
- Cold and flu symptoms — the aches and fever, not the infection.
- Fever in adults.
Disprin Cardiocare (aspirin 100 mg) is used for:
- Preventing a second heart attack or stroke in people who have already had one — the setting where the evidence is strongest and the benefit clearest.
- After stenting, bypass surgery or a diagnosis of angina, on medical advice.
- Reducing clot risk in certain other conditions, as directed by a doctor.
Low-dose aspirin is not a general health measure for otherwise healthy adults. Routine use for prevention in people who have never had cardiovascular disease has largely fallen out of favour, because the bleeding risk outweighs the benefit for most. If you are taking daily aspirin, there should be a specific medical reason and a doctor who decided on it.
How Disprin fits into this medicine category
| Group | Examples | Notes |
|---|---|---|
| Salicylates | Aspirin (Disprin) | Pain and fever at high dose; anti-clotting at low dose |
| Simple analgesics | Paracetamol (Prolief, Donapan) | Gentler on the stomach; no anti-inflammatory effect |
| Anti-inflammatories | Ibuprofen, diclofenac | Similar cautions to aspirin at pain-relieving doses |
| Corticosteroids | Prednisone | Powerful anti-inflammatory, in courses |
| Antiplatelets | Clopidogrel | Alternative or addition to low-dose aspirin |
Aspirin sits in two rows at once, which is precisely what makes it easy to get wrong. See the pain, inflammation and musculoskeletal medicines hub.
What to check before using Disprin
Do not give aspirin to anyone under 16 unless a doctor has specifically directed it. Aspirin in children and teenagers, particularly during a viral illness such as flu or chickenpox, is linked to Reye’s syndrome — a rare but often fatal condition affecting the brain and liver. Use paracetamol for children instead.
Speak to a pharmacist or doctor before taking it if you:
- Have or have had a stomach ulcer, gastritis or bleeding in the digestive tract. Aspirin irritates the stomach lining and impairs clotting, a combination that makes bleeding both more likely and harder to stop.
- Have asthma. A proportion of people with asthma react badly to aspirin and other NSAIDs, sometimes severely.
- Take blood thinners — warfarin, rivaroxaban, apixaban, clopidogrel — or another anti-inflammatory. These combinations substantially raise bleeding risk.
- Take methotrexate, or medicines for gout. Aspirin can raise uric acid levels.
- Have kidney or liver disease, heart failure or uncontrolled high blood pressure.
- Are pregnant. Aspirin is generally avoided, particularly in the last trimester, unless a doctor has specifically prescribed low-dose aspirin for a pregnancy complication — which does happen and should be followed.
- Are breastfeeding.
- Are due for surgery or dental extraction — tell the surgeon or dentist you take aspirin.
Practical points: take it with or after food to reduce stomach irritation. Dissolve effervescent tablets fully in water. Do not take Disprin Plus 10 alongside another anti-inflammatory or another aspirin-containing product — cold and flu remedies sometimes contain aspirin.
Possible cautions and when to ask a pharmacist or doctor
The most common problems are indigestion, heartburn, nausea and stomach discomfort. Aspirin also causes easier bruising and longer bleeding from small cuts, which is expected rather than alarming.
Get emergency help for:
- Vomiting blood, or material that looks like coffee grounds.
- Black, tarry stools — a sign of bleeding in the stomach or upper bowel.
- Severe or persistent stomach pain.
- Swelling of the face, lips or tongue, difficulty breathing, or a sudden worsening of asthma — aspirin-sensitive asthma can be severe.
- Signs of a stroke — sudden weakness, facial droop, slurred speech or a severe unusual headache.
- Ringing in the ears with confusion, rapid breathing or vomiting, which can indicate aspirin overdose. Aspirin overdose is serious and needs emergency care even if the person seems alert.
Contact your doctor if:
- Pain persists beyond a few days, or fever beyond three.
- You develop ringing in the ears or hearing changes.
- You need it regularly for ongoing pain, which needs a diagnosis rather than continuing self-treatment.
- You are on daily low-dose aspirin and notice unusual bruising or bleeding. Do not stop it on your own — after a heart attack, stroke or stent, stopping suddenly raises clot risk. Speak to your doctor first.

Frequently asked questions
What are Disprin tablets used for? Disprin Plus 10 (aspirin 500 mg) is for headache, toothache, period pain, muscular aches and fever. Disprin Cardiocare (aspirin 100 mg) is taken daily to reduce the risk of heart attack and stroke in people who need it.
Is Disprin the same as aspirin? Yes. Both Disprin products contain aspirin, at different strengths for different purposes.
Can I use Disprin Cardiocare for a headache? It is not intended for that. At 100 mg the pain-relieving effect is minimal — the dose is chosen for its effect on platelets.
Can I give it to a child? No. Aspirin should not be given to anyone under 16 unless a doctor directs it, because of the risk of Reye’s syndrome. Use paracetamol instead.
Can I take it with ibuprofen? Not without advice. Combining aspirin with another anti-inflammatory raises the risk of stomach bleeding, and ibuprofen can also interfere with low-dose aspirin’s heart protection.
Should I take a daily aspirin to prevent a heart attack? Only if a doctor has advised it. For people who have never had cardiovascular disease, the bleeding risk generally outweighs the benefit.
Is it safe in pregnancy? Generally avoided, especially late in pregnancy — unless your doctor has specifically prescribed low-dose aspirin, which is sometimes done for good reason.
