Lornbloc is lornoxicam, in 4 mg and 8 mg tablets — a potent anti-inflammatory for short-term moderate pain, arthritis and back pain. Its unusual feature is that it is strong for its dose but clears from the body quickly, which shapes both how it is taken and how it is tolerated.
What is Lornbloc?
The South African Medicine Price Registry lists Lornbloc 4 mg and Lornbloc 8 mg as Schedule 3 film-coated tablets containing lornoxicam.
Lornoxicam is a non-steroidal anti-inflammatory (NSAID) of the oxicam family — the same group as meloxicam and piroxicam. It blocks the COX enzymes that produce prostaglandins, the chemicals responsible for pain, swelling and stiffness where tissue is inflamed.
Two properties define it, and they pull in opposite directions.
It is potent at a small dose. 8 mg of lornoxicam gives pain relief comparable to considerably larger doses of other anti-inflammatories, and studies in post-operative and dental pain have found it comparable to some opioid combinations. The milligram figure is not a measure of strength — comparing 8 mg of lornoxicam with 400 mg of ibuprofen tells you nothing useful.
It clears quickly. Unlike piroxicam and meloxicam, which last around a day, lornoxicam has a short half-life of three to five hours and is taken two or three times daily.
The short half-life is actually an advantage. Long-acting oxicams such as piroxicam accumulate in the body, and that accumulation is why piroxicam has one of the worst gastrointestinal safety records in the class and is now heavily restricted. Lornoxicam does not accumulate, so it delivers oxicam potency without that particular problem.
What it does not escape is the class risk. Lornoxicam blocks COX-1 as well as COX-2, so it carries the full anti-inflammatory profile: stomach irritation and ulcer risk, kidney strain, raised blood pressure, and a small increase in heart attack and stroke risk with regular use. It is a short-course medicine, not one for months of daily use.
What is Lornbloc commonly used for?
- Short-term moderate to severe pain, including after surgery and dental extraction — where its potency is most useful.
- Acute back and neck pain, particularly with muscle spasm.
- Osteoarthritis, for pain and stiffness.
- Rheumatoid arthritis, alongside disease-modifying treatment.
- Sprains, strains and soft tissue injury.
- Period pain.
- Sciatica and other inflammatory nerve root pain.
- Acute gout, in some prescribing.
- Renal colic, where anti-inflammatories are genuinely effective.
It is intended for short courses. The usual pattern is days to a couple of weeks for acute pain. If you need an anti-inflammatory continuously for a chronic joint condition, a once-daily option such as meloxicam is usually more practical, and stomach protection should be part of the plan.
It relieves symptoms, not causes. For osteoarthritis in particular, weight loss, strengthening exercise and physiotherapy change the trajectory in a way no anti-inflammatory does. For back pain, staying active — rather than resting — is what the evidence supports, and the painkiller is there to make that possible.
How Lornbloc fits into this medicine category
| Group | Examples | Notes |
|---|---|---|
| Oxicams | Lornoxicam (Lornbloc), meloxicam, piroxicam | Potent; lornoxicam short-acting, meloxicam once daily |
| Traditional NSAIDs | Ibuprofen, diclofenac, naproxen | Widely used; effective |
| COX-2 selective | Celecoxib, etoricoxib | Gentler on the stomach; cardiovascular caution |
| Simple analgesics | Paracetamol | Pain and fever; no anti-inflammatory effect; safest |
| Opioid combinations | Tramadol/paracetamol | Stronger; dependence risk |
| Corticosteroids | Prednisone | Powerful anti-inflammatory, in courses |
| Topical NSAIDs | Diclofenac gel | Local effect, far lower risk |
Lornoxicam’s place is as a strong short-course option — where an anti-inflammatory is the right class but ibuprofen is not enough, and where an opioid is best avoided.

What to check before using Lornbloc
Do not take another anti-inflammatory alongside it — no ibuprofen, diclofenac, naproxen or aspirin at painkilling doses, and check cold and flu products.
Tell your doctor or pharmacist if you:
- Have or have had a stomach ulcer, gastritis or bleeding in the gut. The most important check with a potent NSAID.
- Have established heart disease, have had a heart attack or stroke, or have heart failure.
- Have high blood pressure.
- Have kidney disease or liver disease.
- Have asthma triggered by anti-inflammatories, or nasal polyps.
- Are over 65, where stomach, kidney and cardiovascular risks all rise substantially.
- Have inflammatory bowel disease.
- Have a bleeding disorder, or are due for surgery.
- Take warfarin or another blood thinner, low-dose aspirin, steroids, an SSRI antidepressant, an ACE inhibitor, ARB or diuretic, lithium, methotrexate, ciclosporin or cimetidine.
- Are pregnant, particularly after 20 weeks, breastfeeding, or planning pregnancy.
Practical points:
- Take it with or just after food.
- Follow the pack instructions for how much and how often. This page does not set doses, and the milligram figure is not comparable with other anti-inflammatories.
- Use it for the short course intended.
- Ask about stomach protection. With a potent NSAID, adding a proton pump inhibitor is standard practice for anyone with ulcer risk and substantially reduces it.
- Drink enough fluid, particularly in hot weather or during illness.
- Do not drive until you know how it affects you — dizziness is not uncommon.
Possible cautions and when to ask a pharmacist or doctor
Common effects: indigestion, nausea, abdominal pain, diarrhoea, headache and dizziness. Taking it with food helps.
Get emergency help for:
- Vomiting blood, or material like coffee grounds.
- Black, tarry stools.
- Severe abdominal pain.
- Chest pain, sudden breathlessness, or signs of a stroke — face drooping, arm weakness, difficulty speaking.
- Swelling of the face, lips or tongue, or difficulty breathing.
- A widespread blistering or peeling rash.
Seek prompt advice for:
- Persistent indigestion or stomach pain. Do not simply take an antacid and continue — an ulcer can bleed without warning, and this is how serious harm from an anti-inflammatory develops unnoticed.
- Wheezing or worsening asthma.
- Reduced urine output, swollen ankles, or unusual tiredness.
- A rise in blood pressure readings.
- A rash or itching.
- Bruising or bleeding more easily.
- Yellowing of the skin or eyes.
Contact your doctor if pain is not controlled, if you need it beyond the intended course, or if the pain is severe, worsening, or comes with fever, weight loss, numbness, weakness or loss of bladder or bowel control. Back pain with any of those, or with loss of bladder or bowel control or numbness around the groin, needs emergency assessment — not a stronger painkiller.

Frequently asked questions
What is Lornbloc 8 mg used for? Short-term moderate to severe pain — after surgery or dental work, acute back pain, sprains, period pain — and arthritis. It contains lornoxicam, a potent anti-inflammatory.
What is Lornbloc 4 mg used for? The same conditions at the lower dose, often as a starting or maintenance strength within a short course.
Is 8 mg a small dose? The number is small but the effect is not. Lornoxicam is potent per milligram — comparing 8 mg of it with 400 mg of ibuprofen tells you nothing useful.
How often do I take it? Usually two or three times daily, with food. It clears from the body in a few hours, unlike once-daily oxicams such as meloxicam.
How is it different from meloxicam? Same family. Meloxicam lasts about 24 hours and is taken once daily; lornoxicam is shorter-acting and more potent per dose, and does not accumulate in the body.
Can I take it with ibuprofen? No. Both are anti-inflammatories, and combining them multiplies stomach and kidney risk without improving relief.
How long can I take it? Short courses — days to a couple of weeks. For ongoing joint conditions, a once-daily option with stomach protection is usually more practical.
Should I take something to protect my stomach? If you have any ulcer risk, ask. Adding a proton pump inhibitor is standard practice with a potent anti-inflammatory.
