Feldene (Piroxicam) – Patient Information (Australia)

Feldene is a brand of piroxicam, a medicine from the non-steroidal anti-inflammatory drug (NSAID) family. It is used to reduce pain and inflammation, particularly for certain arthritis and joint conditions.

This page explains how Feldene works, how it’s usually taken, what to watch for, and how it fits into treatment options in Australia. Always follow the instructions on your product label and the advice of your healthcare professional.

Quick overview

• Active ingredient: Piroxicam
• Medicine class: NSAID (anti-inflammatory pain reliever)
• Common uses: Pain and inflammation from conditions such as osteoarthritis and rheumatoid arthritis (as determined by your clinician)
• How it’s taken: Usually once daily (depending on the prescribed strength and plan)
• Key safety considerations: Stomach irritation/ulcers, kidney effects, cardiovascular risk in some people, interactions with other medicines (especially blood thinners)
• Food considerations: Taking with food may reduce stomach upset, though it doesn’t eliminate all risks

Basic product information

Brand name: Feldene

Generic name: Piroxicam

Form and strengths: Available as tablets in commonly used strengths (availability may vary). Check the specific product listing.

In Australia, medicine names, packaging and approved details can vary by manufacturer and formulation. If you’re unsure which version you have, confirm the active ingredient and strength on the box or label.

How Feldene works (mechanism of action)

Piroxicam reduces pain and inflammation mainly by decreasing production of prostaglandins—chemicals involved in inflammation, pain signalling, and fever. Like other NSAIDs, piroxicam works by inhibiting enzymes called cyclo-oxygenases (COX-1 and COX-2).

By lowering prostaglandins, Feldene can help:

• Reduce inflammation around joints
• Relieve pain
• Improve mobility and stiffness related to inflammatory conditions

Pharmacokinetics (how the body handles it)

Understanding how piroxicam behaves in the body can help you take it safely and consistently. While exact values can vary among individuals, the following describes general pharmacokinetic features.

• Absorption: Piroxicam is absorbed after oral administration, with peak blood levels typically reached several hours after taking.
• Half-life: It has a long half-life, which is one reason it’s often dosed once daily.
• Distribution: It distributes into body tissues, including sites relevant to inflammation.
• Metabolism: Mainly processed in the liver.
• Elimination: Metabolites are eliminated primarily via the kidneys and partly via bile/faeces.

Because piroxicam stays in the body for a long time, effects may continue after a dose change. For some people, steady pain control may take days.

Typical uses and indications

Feldene (piroxicam) is an NSAID used for conditions where inflammation and pain are key symptoms. The exact suitability depends on diagnosis, medical history, and risk factors.

Common indications may include:

• Osteoarthritis (pain and stiffness in joints)
• Rheumatoid arthritis (inflammatory joint disease)
• Other inflammatory musculoskeletal conditions where an NSAID is appropriate (as advised by your clinician)

Not all types of pain respond the same way to NSAIDs. If your symptoms don’t improve, it’s important to review the plan rather than simply increasing the dose.

Dosage and timing

Dosing depends on the formulation, the condition being treated, and individual risk factors. Always follow the dose on your product label or provided instructions.

How to take Feldene

• Consistency matters: Taking it at the same time each day may help maintain stable levels.
• With food: If it upsets your stomach, taking with or after meals may be more comfortable.
• Swallow whole: Tablets are generally swallowed with water unless your product instructions say otherwise.
• Don’t exceed dose: Higher doses increase the risk of side effects, especially stomach bleeding and kidney problems.

Typical dosing pattern

Piroxicam is commonly administered once daily because of its long duration in the body. Your healthcare professional may recommend a specific daily dose and schedule.

When you may notice relief

• Short-term: Some people feel pain relief within days.
• Inflammatory conditions: Full benefit may take longer, often several days to 1–2 weeks.

If you need ongoing NSAID treatment, regular review is recommended to ensure benefits continue to outweigh risks.

Food interactions and stomach protection

Food can influence comfort and, to some extent, side effects. It does not remove NSAID-related risks, but it can make treatment easier to tolerate.

Taking with food

• With meals: Often reduces nausea, indigestion, and stomach irritation.
• Avoid taking on an empty stomach: If you’ve had heartburn or gastritis before, this is especially relevant.

Gastro-protective medicines (if applicable)

If you’re at higher risk of gastric irritation (for example, history of ulcer, older age, or combining with other medicines), clinicians may consider protective strategies (such as gastro-protective agents). Use only what has been advised for your situation.

Alcohol and Feldene interactions

Alcohol and NSAIDs together can increase the chance of stomach irritation and bleeding. Alcohol may also worsen dizziness or reduce your ability to recognise side effects.

• Best approach: Avoid or minimise alcohol while taking Feldene.
• Higher risk: If you drink heavily or have a history of ulcers or bleeding, extra caution is needed.
• Seek advice urgently: If you notice black/tarry stools, vomiting blood, or severe abdominal pain.

Medicine interactions (important)

NSAIDs can interact with many medicines, altering bleeding risk, kidney function, blood pressure, and other effects. Tell your healthcare professional or pharmacist about all medicines you take, including over-the-counter products and supplements.

Common interaction categories

• Blood thinners (anticoagulants) such as warfarin, and medicines that affect clotting: increased risk of bleeding.
• Antiplatelets (e.g., aspirin in some regimens, clopidogrel): increased risk of gastrointestinal bleeding.
• Other NSAIDs (e.g., ibuprofen, naproxen, diclofenac): increased risk without additional benefit in most cases.
• Diuretics (e.g., hydrochlorothiazide, furosemide) and ACE inhibitors/ARBs (e.g., enalapril, lisinopril, losartan, valsartan): may affect kidney function and potassium balance.
• Selective serotonin reuptake inhibitors (SSRIs) (e.g., sertraline, fluoxetine): may raise risk of stomach bleeding.
• Lithium and methotrexate: NSAIDs can increase levels and toxicity; monitoring may be required.
• Prednisone/corticosteroids: increased risk of stomach irritation/ulcer.
• Herbal products (e.g., St John’s wort) and supplements: may affect metabolism or bleeding risk—check with a pharmacist.

If you’re taking multiple medicines, ask your pharmacist to review interactions before starting or continuing piroxicam.

Safety profile: who should be careful

Like all NSAIDs, piroxicam has potential side effects. Many people tolerate it well when used correctly, but certain risks are important to understand.

Seek urgent medical help if you experience

• Signs of stomach bleeding: black/tarry stools, vomiting blood, coughing up blood
• Severe allergic reactions: swelling of face/lips, wheezing, rash with blistering
• Chest pain, sudden shortness of breath, weakness on one side, or speech difficulties
• Severe skin reactions (rare but serious)
• Marked reduction in urine output or symptoms of fluid retention

Common side effects

• Indigestion, heartburn, stomach discomfort
• Nausea
• Headache
• Dizziness
• Fluid retention or mild swelling

Less common but serious risks

• Gastrointestinal ulceration and bleeding
• Kidney injury (especially with dehydration or kidney disease)
• Increased cardiovascular risk in some people, particularly with long-term use or higher doses
• Blood pressure increases in some individuals
• Worsening of asthma in some patients who are sensitive to NSAIDs
• Liver enzyme changes (rare)

People who need extra caution

• History of peptic ulcer or GI bleeding
• Older adults (higher risk of side effects)
• Heart disease, stroke history, uncontrolled blood pressure, or significant cardiovascular risk factors
• Kidney disease, dehydration, or conditions affecting blood flow to kidneys
• Asthma or known NSAID sensitivity
• Those taking interacting medicines (blood thinners, SSRIs, steroids, other NSAIDs, etc.)
• Pregnancy: NSAIDs can be harmful later in pregnancy; discuss timing and suitability with your clinician

Practical use tips (how to get the benefit safely)

• Use the lowest effective dose for the shortest appropriate time: This reduces risk.
• Don’t combine with other NSAIDs: Avoid ibuprofen, naproxen, diclofenac, or aspirin for pain unless advised.
• Stay hydrated: Dehydration increases kidney risk.
• Be cautious with activity: If you feel dizzy, avoid driving or operating machinery.
• Monitor for warning signs: Pay attention to stomach symptoms, unusual bruising/bleeding, reduced urination, or swelling.
• Regular review: If using regularly, schedule check-ins for blood pressure, kidney function, and overall risk assessment.
• Consider non-medicine options: Gentle exercise, physiotherapy, weight management, heat/cold therapy, and ergonomic changes can complement medicine treatment.

Alternative options for arthritis and joint pain

NSAIDs are one approach. Depending on your condition, risk factors, and preferences, other therapies may be considered.

Common alternatives

• Paracetamol (acetaminophen): May help pain; it doesn’t treat inflammation.
• Topical NSAIDs (e.g., topical diclofenac): can reduce local pain with lower systemic exposure for some people.
• Other oral NSAIDs: different NSAIDs may be selected based on tolerability and risk profile.
• Non-drug strategies: Physiotherapy, strengthening, mobility work, braces/orthotics, pacing, and heat/cold.
• For inflammatory arthritis: Disease-modifying treatments (for example, DMARDs) may be required to manage the underlying condition—these are determined by specialist assessment.

If you’re considering switching, ask your pharmacist or clinician about washout timing, dose equivalence, and interaction risks.

Australia: market and legal context

In Australia, medicines are classified and regulated under the national medicines framework. How a medicine is supplied (for example, via prescription-only vs pharmacist-only/over-the-counter pathways) depends on the specific product strength and regulatory status.

Availability can also be affected by supply arrangements, manufacturer availability, and pharmacy policies. If you can’t find Feldene in stock, a pharmacist may discuss alternative available NSAIDs or different formulations that suit your needs.

Always check the product listing for the exact strength and form you are buying.

Recent guidance and practical updates (general)

In line with ongoing safety focus across Australia and internationally, NSAID use is often guided by the principles of risk assessment and individualised benefit. Common themes in recent clinical practice include:

• Using the lowest effective dose and limiting duration where possible
• Reviewing GI and cardiovascular risks in people needing long-term NSAIDs
• Considering gastro-protective strategies for those at higher GI risk
• Checking kidney function (especially in older adults or those with dehydration/renal risk)
• Avoiding concurrent NSAIDs unless explicitly advised

If you have been on piroxicam for a while, it’s a good idea to discuss periodic monitoring and whether the dose or plan still remains the best option for you.

Delivery and availability (online pharmacy)

Online pharmacies in Australia commonly offer delivery to eligible areas. Availability may vary by:

• Stock levels from the supplier
• Whether the exact strength and pack size is in demand
• Any temporary national or distributor supply limitations

For the most accurate delivery timeline, check the shipping information at checkout and the product page for current stock status. If Feldene isn’t available, a pharmacist may offer an alternative NSAID based on your needs.
