Feldene (Piroxicam) — Patient Information (Australia)

Feldene is a brand of piroxicam, a medicine from the non-steroidal anti-inflammatory drugs (NSAIDs) family. It is used to help relieve pain, inflammation (swelling), and stiffness associated with a number of musculoskeletal conditions.

This guide is designed to be patient-friendly and Australia-focused. It covers what Feldene is, how it works, how it behaves in the body, how and when it’s taken, food and alcohol interactions, key safety information, practical tips, and common questions.

Quick overview

• Active ingredient: Piroxicam
• Drug class: NSAID (anti-inflammatory pain reliever)
• Common effects: Reduces pain and inflammation; helps with stiffness
• Typical dosing form: Tablets (strengths vary by product presentation)
• How often: Often once daily (depending on the prescribed regimen)

Note: Always follow the dose and instructions on your specific product label or from your healthcare professional.

What is Feldene?

Feldene is a prescription NSAID containing piroxicam. NSAIDs work by reducing inflammation and pain signals in the body. Piroxicam is particularly used for conditions where inflammatory pain and stiffness are prominent.

Feldene may be considered for long-term management of certain chronic inflammatory conditions, but the risk–benefit balance depends on your health history (especially your stomach, kidney, heart, and blood pressure).

Mechanism of action (how it works)

Piroxicam works mainly by inhibiting cyclo-oxygenase (COX) enzymes, particularly COX-1 and COX-2. These enzymes help produce prostaglandins—chemicals involved in:

• Inflammation (swelling and redness)
• Pain transmission
• Fever (in some settings)
• Protective functions in the stomach and kidneys

By lowering prostaglandin production, piroxicam reduces inflammation and provides pain relief. Because prostaglandins also help protect the stomach lining and support kidney blood flow, NSAIDs can increase risks such as gastric irritation, ulcers, or kidney strain.

Pharmacokinetics (how the body handles piroxicam)

Understanding pharmacokinetics can help explain why Feldene is dosed once daily in many cases and why missing doses can matter.

Practical implication: Because piroxicam persists in the body, side effects may also develop over days. If you stop Feldene, its effects (including risks) may not disappear immediately.

Typical uses (indications)

Feldene is used to relieve symptoms of inflammatory and painful conditions, including:

• Rheumatoid arthritis
• Osteoarthritis (degenerative joint disease)
• Ankylosing spondylitis
• Other inflammatory musculoskeletal disorders where an NSAID is appropriate

Your healthcare professional will consider your symptoms, previous response to NSAIDs, other medicines, and personal risk factors (such as ulcers or cardiovascular disease).

How and when to take Feldene

Always follow the dosing instructions on your product label or as advised. Feldene dosing may vary depending on your condition and risk profile.

Typical timing

• Once daily regimens are common due to the medicine’s duration of action.
• Try to take it at a consistent time each day for steadier symptom control.
• If you miss a dose, take it when you remember unless it’s close to the next dose. Do not double doses.

Dose (general guidance)

Dosing depends on the indication and your overall health. Common clinical regimens for piroxicam have included once-daily dosing within a therapeutic range, sometimes started at the lowest effective dose.

Important: For the exact dose and maximum daily dose relevant to your product and situation, refer to the label provided with your medicine and/or the directions supplied by your healthcare professional.

Should Feldene be taken with food?

NSAIDs can irritate the stomach. Taking piroxicam with food or milk may reduce stomach discomfort.

Food interactions and effects on absorption

• Food may help protect the stomach and improve tolerability.
• Food may delay absorption slightly for some NSAIDs; however, this usually does not significantly reduce effectiveness.
• If you experience nausea, heartburn, or upper abdominal pain, discuss with your healthcare professional—your regimen may need adjustment.

Tip: Avoid taking it on an empty stomach if you are prone to gastritis, reflux, or ulcers.

Alcohol interactions

Combining NSAIDs such as piroxicam with alcohol can increase the likelihood of:

• Gastrointestinal bleeding
• Gastric irritation
• Stomach ulcers and slower healing

If you choose to drink alcohol, keep it minimal and avoid alcohol during periods when you have stomach symptoms. If you have a history of ulcers or gastrointestinal bleeding, discuss alcohol use with a healthcare professional.

Medicine interactions (important)

Feldene can interact with many medicines. Before starting piroxicam, make sure your healthcare professional knows about all medicines and supplements you take, including:

Higher-risk interactions

• Other NSAIDs (e.g., ibuprofen, naproxen, diclofenac, aspirin used for pain):
  Increase risk of stomach bleeding and kidney effects. Do not combine unless specifically advised.
• Anticoagulants (e.g., warfarin):
  Higher risk of bleeding.
• Antiplatelet medicines (e.g., clopidogrel):
  May increase bleeding risk.
• Corticosteroids (e.g., prednisone):
  May increase gastrointestinal ulcer risk.
• SSRIs/SNRIs (e.g., sertraline, fluoxetine, venlafaxine):
  Increased risk of GI bleeding in some patients.
• Diuretics and blood pressure medicines:
  NSAIDs can affect kidney function and may reduce the effect of some antihypertensives.
• ACE inhibitors/ARBs (e.g., perindopril, enalapril, losartan, valsartan):
  Combination with NSAIDs can increase risk of kidney strain, especially in dehydration or in older adults.
• Lithium:
  NSAIDs may increase lithium levels, raising toxicity risk.
• Methotrexate:
  May increase methotrexate levels in some situations.
• Digoxin:
  NSAIDs may affect digoxin levels or kidney function.
• Cyclosporine/tacrolimus:
  Increased kidney risk when combined with NSAIDs.
• Antacids and some stomach medicines:
  Generally, these may reduce irritation, but they don’t replace medical advice about interactions.

Herbal and supplement considerations

• St John’s wort: may affect drug metabolism.
• Ginkgo biloba, fish oil, or other products that can affect bleeding: discuss if you also take blood thinners or have ulcer risk.

Advice: Keep a written list of your medicines and show it to your pharmacist or doctor. If you start Feldene, avoid starting new medicines (including “natural” products) without checking safety.

Safety profile: who should take extra care?

Feldene can be very effective for pain and inflammation, but it also carries potential risks common to NSAIDs. Some people should be extra cautious or may be advised not to use certain NSAIDs.

Common side effects

• Stomach discomfort, heartburn, nausea
• Headache or dizziness
• Fluid retention (swelling, weight increase)

Serious risks (seek urgent medical help)

Stop and seek urgent medical attention if you develop signs of serious complications such as:

• GI bleeding: vomiting blood, black/tarry stools, or blood in stool
• Severe allergic reaction: swelling of face/lips, wheezing, difficulty breathing, widespread rash
• Serious skin reactions (rare): blistering, peeling, severe rash
• Signs of kidney problems: reduced urine output, sudden swelling, severe fatigue
• Chest pain or stroke symptoms: especially if you have cardiovascular risk factors

Higher-risk groups

Discuss your suitability carefully if you have any of the following:

• History of stomach ulcer or GI bleeding
• Known heart disease, history of stroke, or high cardiovascular risk
• Kidney disease or dehydration
• Uncontrolled high blood pressure
• Asthma triggered by NSAIDs
• Older age (risk of side effects tends to be higher)
• Concurrent use of medicines that increase bleeding risk

General safety principles

• Use the lowest effective dose for the shortest possible duration.
• Avoid combining with other NSAIDs.
• Regularly review your need for continued NSAID therapy with a healthcare professional.

Practical use tips (to improve comfort and safety)

• Take with food if you get stomach irritation.
• Stay hydrated, especially in hot weather or if unwell.
• Monitor blood pressure if you have hypertension.
• Watch for stomach symptoms such as burning, pain, or changes in stool colour.
• If you’ve been taking it longer-term, ask your pharmacist/doctor whether you need periodic monitoring (e.g., kidney function, blood counts, or other tests).
• Don’t “stack” painkillers: avoid taking multiple NSAIDs together.
• For breakthrough pain, ask what you can safely use alongside piroxicam (many people can use paracetamol, but individual advice matters).

Alternative options

If Feldene is not suitable—because of side effects, interactions, or inadequate symptom relief—there are alternative approaches. Options include:

Other medicines (NSAIDs and non-NSAIDs)

• Different NSAIDs (e.g., celecoxib, ibuprofen, naproxen, diclofenac): may differ in GI and cardiovascular risk profiles.
• Non-NSAID pain relief such as paracetamol for pain control in some situations.
• Topical anti-inflammatory medicines (e.g., topical NSAIDs) for certain joint conditions—often with lower systemic exposure.
• For some inflammatory diseases, other disease-specific medicines may be used by specialists (e.g., DMARDs for rheumatoid arthritis).

Non-medicine approaches

• Physical therapy and strengthening exercises
• Heat/cold therapy
• Weight management and joint-friendly activity modification
• Assistive devices and ergonomic adjustments

Your healthcare professional can help you choose alternatives based on your condition and risk factors.
