Pyrocaps contains piroxicam 20 mg, a long-acting anti-inflammatory taken once daily. It is used for osteoarthritis, rheumatoid arthritis and ankylosing spondylitis. Piroxicam carries a higher risk of stomach ulceration and serious skin reactions than most NSAIDs, so it is a second-line choice.
What is Pyrocaps?
Pyrocaps contains piroxicam 20 mg, a non-steroidal anti-inflammatory drug. It is a Schedule 3 medicine.
Piroxicam blocks cyclo-oxygenase enzymes, reducing the prostaglandins that drive inflammation, swelling and pain. In that respect it works like ibuprofen or diclofenac.
What distinguishes it is duration. Piroxicam has a very long half-life — it stays in the body for around two days, far longer than most NSAIDs. That allows once-daily dosing, which suits a chronic condition, and it produces steady rather than fluctuating levels.
The same property is its main drawback. A medicine that lingers also lingers when something goes wrong. If piroxicam causes a stomach problem or a reaction, stopping it does not clear it quickly, and the exposure continues for days. Combined with piroxicam’s relatively high ulcer rate, that has changed how it is positioned.
Regulators in several countries restricted piroxicam because of its gastrointestinal and skin reaction profile: it is no longer recommended as a first-choice NSAID, is not for acute pain or short-term conditions, and is generally started only under specialist review with a stomach-protecting medicine alongside.
That is not a reason to stop a prescription that is working. It is a reason to know why you are on it rather than something else.
What is Pyrocaps commonly used for?
Piroxicam is prescribed for chronic inflammatory joint conditions:
- Osteoarthritis, for pain and stiffness.
- Rheumatoid arthritis, alongside disease-modifying treatment.
- Ankylosing spondylitis, inflammatory arthritis of the spine.
That list is deliberately short. Piroxicam is not intended for acute pain — headache, a sprain, dental pain, period pain — where its long duration is a liability rather than an advantage and a shorter-acting NSAID such as ibuprofen is safer and works faster.
As with any anti-inflammatory in arthritis, it relieves symptoms. In osteoarthritis it does not repair cartilage or halt progression. In rheumatoid arthritis, preventing joint damage is the job of disease-modifying medicines such as methotrexate — piroxicam controls symptoms alongside them.
Exercise, weight management and physiotherapy genuinely reduce how much anti-inflammatory is needed in osteoarthritis, and are worth pursuing properly.
How Pyrocaps fits into this medicine category
| Group | Examples | Note |
|---|---|---|
| Simple analgesics | Paracetamol (Donapan) | Try first; safest stomach profile |
| Standard NSAIDs | Ibuprofen, diclofenac, naproxen | Shorter-acting; first-line choices |
| Long-acting NSAIDs | Piroxicam (Pyrocaps) | Once daily; higher ulcer and skin risk |
| COX-2 selective | Meloxicam (Coxflam), celecoxib (Celebrex) | Gentler on the stomach |
| Corticosteroids | Prednisone | Far stronger; short courses or injection |
If you are on piroxicam for a chronic joint condition and have not discussed alternatives, it is a reasonable conversation to have. See the pain, inflammation and musculoskeletal medicines hub.
What to check before using Pyrocaps
Take it once daily with food, at the same time each day.
Never combine it with another anti-inflammatory, including over-the-counter ibuprofen and combination painkillers.
Ask whether you should be on a stomach-protecting medicine. Current guidance is that piroxicam is prescribed with one, and if you have not been given one, that is worth raising.
Tell your prescriber or pharmacist if:
- You have a history of stomach ulcers, bleeding, reflux or gastritis. Piroxicam has a higher ulcer rate than most NSAIDs.
- You have kidney disease, or become dehydrated easily.
- You have heart disease, heart failure, high blood pressure, or have had a stroke.
- You have liver disease.
- You have asthma.
- You have a history of serious skin reactions, or a rash on any previous medicine.
- You take blood thinners, low-dose aspirin, a corticosteroid, an SSRI antidepressant, a diuretic, an ACE inhibitor, lithium or methotrexate.
- You are pregnant or breastfeeding.
- You are over 65, where stomach and kidney risks are markedly higher.
Expect periodic monitoring — blood pressure, kidney function and blood counts on long-term treatment.
Follow the dispensing label. This page does not set doses.
Possible cautions and when to ask a pharmacist or doctor
Serious skin reactions deserve specific attention with piroxicam. It carries a higher risk than most NSAIDs of Stevens-Johnson syndrome and toxic epidermal necrolysis — rare, but severe. Stop and seek medical help immediately for a rash that blisters or peels, sores in the mouth, eyes or genitals, or a widespread rash with fever. Do not wait to see whether it settles, and do not assume it is unrelated because you have taken the medicine for months.
Stomach. Ulcers and bleeding can occur without warning pain, and piroxicam’s long duration means exposure continues for days after stopping.
Kidneys. Function can decline, particularly in older people, on blood-pressure medicines, or when dehydrated. During an illness with vomiting or diarrhoea, ask whether to pause it.
Heart and blood pressure. NSAIDs can raise blood pressure and worsen heart failure.
Review it periodically. Because piroxicam is a second-line NSAID with a specific risk profile, long-term use warrants an occasional check that it is still the right choice.
Seek urgent medical attention for a blistering or peeling rash, mouth or eye sores, a widespread rash with fever, stomach pain, vomiting blood or coffee-ground material, black tarry stools, breathlessness, chest pain, one-sided weakness, marked swelling, significantly reduced urine, or yellowing of the skin or eyes.

Frequently asked questions
What is Pyrocaps 20 mg used for? Chronic inflammatory joint conditions — osteoarthritis, rheumatoid arthritis and ankylosing spondylitis. It contains piroxicam.
Can I take it for a headache or a sprain? No. Piroxicam is not intended for acute pain. Its long duration is a drawback there, and a shorter-acting NSAID is safer and faster.
Why is it taken only once a day? Piroxicam stays in the body around two days, far longer than most anti-inflammatories, so one capsule gives steady cover.
Why do I need a stomach-protecting medicine with it? Piroxicam has a higher ulcer risk than most NSAIDs, and its long duration means exposure continues after stopping. Current guidance pairs it with stomach protection.
I have developed a rash. What should I do? Contact your prescriber. Seek help immediately if it blisters or peels, involves the mouth or eyes, or comes with fever — piroxicam carries a specific risk of serious skin reactions.
Should I be on something else instead? Possibly. Piroxicam is a second-line NSAID, so if it has not been reviewed recently, ask your doctor whether an alternative would suit you better.
