Feldene (Piroxicam) — Patient Information

Feldene contains piroxicam, a medicine from the non-steroidal anti-inflammatory drug (NSAID) group. It helps relieve pain and inflammation in conditions such as arthritis and certain musculoskeletal problems. This page explains how Feldene works, how it’s used, safety considerations, and what to expect when taking it in Australia.

1) Basic product information

Note: Brand availability, strengths, and packaging can vary. Always confirm your specific product strength on the box or label.

2) How Feldene works (mechanism of action)

Piroxicam is an NSAID. NSAIDs reduce pain and inflammation by lowering the production of certain chemicals in the body called prostaglandins. Prostaglandins are involved in:

• Inflammation (swelling, redness)
• Pain (pain signalling)
• Fever (less commonly relevant in arthritis)

Feldene works mainly by inhibiting cyclo-oxygenase (COX) enzymes, which are responsible for prostaglandin formation.

3) Pharmacokinetics (how the body handles piroxicam)

Pharmacokinetics describes what the body does with the medicine—absorption, distribution, metabolism, and elimination. While exact values can vary between individuals, the key points for piroxicam include:

• Absorption: Piroxicam is absorbed after oral administration.
• Onset: Pain relief may begin within hours, but full anti-inflammatory benefit can take several days.
• Peak concentration: It generally reaches peak levels after oral dosing (time to peak can vary).
• Half-life: Piroxicam has a long duration in the body, which is why it is often dosed once daily.
• Metabolism and elimination: The medicine is metabolised in the liver and eliminated mainly through the kidneys and/or bile.

Practical takeaway: Because piroxicam stays in the body for a longer time, missing doses or dose changes should be planned carefully, and you should avoid overlapping NSAID use.

4) Typical uses

Feldene is used for inflammatory and painful conditions, including:

• Arthritis (e.g., rheumatoid arthritis, osteoarthritis)
• Ankylosing spondylitis (an inflammatory condition affecting the spine)
• Acute gout flares (where an NSAID is appropriate)
• Musculoskeletal pain associated with inflammation in some cases

Because individual circumstances differ, your clinician will consider your medical history, other medicines, and risk factors when choosing an appropriate NSAID.

5) Timing and how to take Feldene

When should you take it?

Feldene is typically taken once daily because piroxicam has a relatively long action. Choose a consistent time each day to maintain steady effects.

How long until it works?

• For pain: some relief may be felt within hours.
• For inflammation: it may take several days to reach best effect.

What if you miss a dose?

• Take it when you remember on the same day.
• If it is close to the next dose, skip the missed dose.
• Do not double up to make up for a missed tablet.

How to swallow

Swallow tablets with water. If you have trouble swallowing, discuss options with a pharmacist.

6) Food interactions (and stomach comfort)

Taking NSAIDs with food may reduce stomach irritation for some people.

• With food or after meals: often helps lower the chance of indigestion, nausea, and stomach pain.
• Empty stomach: may increase the risk of gastric discomfort and ulcer-related symptoms.

Tip: If Feldene upsets your stomach, consider taking it with meals (unless your clinician/pharmacist has advised otherwise).

7) Alcohol and medicine interactions

Alcohol

Combining NSAIDs with alcohol can increase the risk of stomach irritation, bleeding, and ulcers. For the safest approach:

• Avoid alcohol if you have a history of ulcers or GI bleeding.
• If you do drink, keep amounts minimal and take with food.

Important medicine interactions

NSAIDs can interact with other medicines. Talk with a pharmacist if you use any of the following:

• Other NSAIDs (e.g., ibuprofen, naproxen, diclofenac): increases GI and kidney risk—avoid combining.
• Aspirin (for heart protection or pain): may increase bleeding risk depending on dose and indication.
• Blood thinners (e.g., warfarin): higher bleeding risk.
• Antiplatelets (e.g., clopidogrel): may increase bleeding risk.
• SSRIs/SNRIs for depression/anxiety: combined with NSAIDs may raise GI bleeding risk.
• Corticosteroids (e.g., prednisone): can increase ulcer risk when used together.
• Some blood pressure medicines:
  • ACE inhibitors (e.g., perindopril, enalapril) and ARBs (e.g., losartan, valsartan)
  • NSAIDs may reduce kidney function in some people, particularly if dehydrated.
• Diuretics (e.g., hydrochlorothiazide, furosemide): may increase kidney-related risk when combined with NSAIDs.
• Lithium: NSAIDs can raise lithium levels.
• Methotrexate: may increase methotrexate-related toxicity at certain doses.
• Diabetes medicines:
  • NSAIDs can affect blood sugar in some people; monitoring may be needed.

Always check: Bring a list of your medicines (including over-the-counter products and supplements) to your pharmacist for a safety check.

8) Indications (what Feldene is used to treat)

In practice, piroxicam is used to relieve symptoms caused by inflammation. Common indications include:

• Rheumatoid arthritis
• Osteoarthritis
• Ankylosing spondylitis
• Acute gout (in situations where an NSAID is suitable)
• Other painful inflammatory conditions as determined by your healthcare professional

Whether Feldene is suitable for you depends on your health history, including stomach, kidney, and cardiovascular risk factors.

9) Dosing (general guidance)

Important: Use your specific label directions. Dosing may vary by condition, age, and risk factors.

Common dosing approach

• Piroxicam is frequently prescribed at once-daily dosing due to its longer effect.
• The lowest effective dose for the shortest possible duration is generally recommended for NSAIDs to reduce side effects.

Adjustments in higher-risk situations

Your clinician/pharmacist may recommend dose adjustments or closer monitoring if you have:

• A history of stomach ulcers or bleeding
• Kidney disease or risk of dehydration
• Heart disease or increased cardiovascular risk
• Older age
• Multiple medicines that affect bleeding or kidney function

Stop and seek advice if warning signs occur

Do not ignore symptoms that could indicate serious complications (see “Safety profile” below).

10) Safety profile (side effects and when to get help)

Like all medicines, Feldene can cause side effects. Most are mild, but serious reactions can occur. It’s important to know what to watch for.

Common side effects

• Indigestion, heartburn, stomach discomfort
• Nausea
• Headache
• Dizziness
• Swelling due to fluid retention (in some people)

Serious risks (get urgent medical help)

Seek urgent help if you experience:

• Signs of stomach or bowel bleeding:
  • Vomiting blood or “coffee-ground” material
  • Black/tarry stools
  • Blood in stool
• Allergic reaction:
  • Swelling of the face/lips, wheezing, difficulty breathing
  • Severe rash or blisters
• Signs of kidney problems:
  • Reduced urination, sudden weight gain, severe swelling
• Chest pain, shortness of breath, weakness on one side (possible cardiovascular event)
• Severe skin reactions (rare but serious), such as widespread rash with fever or peeling skin

Who needs extra caution?

Talk to a pharmacist or clinician before using piroxicam if you have any of the following:

• History of peptic ulcer or GI bleeding
• Asthma triggered by aspirin/NSAIDs
• Kidney disease, dehydration, or heart failure
• High cardiovascular risk (e.g., prior heart attack or stroke)
• Conditions that increase bleeding risk or use of interacting medicines
• Pregnancy (especially later pregnancy) or breastfeeding (discuss with a healthcare professional)

11) Practical use tips

• Take with food to reduce stomach irritation.
• Avoid combining NSAIDs: do not take ibuprofen, naproxen, or diclofenac at the same time unless specifically advised.
• Use the lowest effective dose and review need for continued therapy.
• Stay hydrated, particularly if you’re unwell or the weather is hot.
• Monitor for side effects, especially during the first weeks of treatment.
• Keep an eye on bleeding risk if you take blood thinners, antiplatelets, or corticosteroids.
• Report unusual symptoms promptly (black stools, persistent stomach pain, rash, sudden swelling).

12) Alternative options

Depending on your condition and risk factors, alternatives to piroxicam may include:

Other NSAIDs

• Ibuprofen, naproxen, diclofenac (choice depends on tolerability and risk)

Non-NSAID pain relief

• Paracetamol (acetaminophen) for pain relief (usually less effect on inflammation)

Non-drug approaches

• Physiotherapy, stretching and strengthening
• Heat/cold therapy
• Weight management (for osteoarthritis)
• Exercise programs tailored to joint and back health

For arthritis: Many people also benefit from disease-modifying treatments under specialist guidance. Your clinician can help create a plan that balances symptom relief with long-term joint health.

13) Market and legal context in Australia (high-level)

In Australia, medicines are regulated through the Therapeutic Goods Administration (TGA) and listed on the Australian Register of Therapeutic Goods (ARTG). NSAIDs such as piroxicam are subject to prescribing and dispensing rules based on strength and intended use.

Because safety considerations (including gastrointestinal, kidney, and cardiovascular risks) are important, Feldene is generally provided with appropriate healthcare oversight. If you have concerns about suitability, a pharmacist can help you understand risks and safer alternatives.

Recent guidance (general trends)

Recent years have seen consistent emphasis across Australia and internationally on:

• Using NSAIDs at the lowest effective dose and for the shortest duration necessary
