Feldene (Piroxicam) – Patient Information (UK)
Feldene is a pain-relieving anti-inflammatory medicine containing piroxicam, which belongs to the non-steroidal anti-inflammatory drug (NSAID) family. It is used for conditions where inflammation and pain go together, such as painful joints and certain long-term rheumatic problems.
This guide explains how Feldene works, how it is usually taken, what to watch for, and how to use it safely. If you are unsure whether it is right for you, speak with a qualified healthcare professional.
Quick overview

How Feldene works (mechanism of action)
Piroxicam helps reduce pain, swelling and inflammation. Like other NSAIDs, it works by blocking enzymes called cyclo-oxygenase (COX) enzymes. COX enzymes help produce prostaglandins—chemicals that contribute to inflammation and pain.
By lowering prostaglandin production, Feldene can:
- Reduce inflammation around joints and tissues
- Relieve pain
- Help stiffness, particularly in inflammatory joint conditions
Pharmacokinetics: how the body handles piroxicam
Understanding pharmacokinetics can help explain why Feldene may take time to work and why dosing schedules matter. Below is an overview of typical behaviour of piroxicam in the body.
- Absorption: Piroxicam is absorbed after oral use.
- Onset: Some pain relief may be noticed within the first days, but full effect for chronic conditions can take longer.
- Time to peak: The medicine reaches peak levels in the blood after a few hours (exact timing can vary).
- Half-life: Piroxicam has a relatively long half-life, which is why dosing is often once daily.
- Distribution: It spreads into tissues where it can help target inflammation.
- Metabolism and elimination: It is processed mainly in the liver and removed via the kidneys and/or bile, depending on metabolism.
Because piroxicam can persist in the body longer than some other painkillers, the balance between benefit and risk is especially important—particularly with higher doses or prolonged use.
Typical uses and indications (UK)
Feldene is commonly used for painful, inflammatory conditions. Indications may vary depending on your individual assessment and the product you are using.
Examples of conditions it may be used for
- Rheumatoid arthritis (inflammatory joint disease)
- Osteoarthritis (painful degeneration with inflammation)
- Ankylosing spondylitis (inflammatory back/hip condition)
- Acute flares where inflammation contributes to pain and stiffness
Feldene may be chosen when an NSAID is considered appropriate and when piroxicam’s dosing schedule and overall risk profile are suitable for the patient.
When to take Feldene (timing and routine)
Many people take Feldene once daily. The best timing for you depends on how your symptoms behave and how you react to the medicine.
General timing tips
- Try consistency: Taking it at the same time each day can help maintain steady effect.
- Follow your local instructions: Use the dosing schedule provided by your clinician or the product label.
- Expect gradual benefit: For long-term joint conditions, improvement may build over days.
- Stop and seek advice if severe side effects occur: Especially signs of allergy or gastrointestinal bleeding.
Missed dose
If you miss a dose, take it when you remember unless it is close to the next dose. Do not take a double dose to make up for a missed tablet. If you are unsure, check the medicine information leaflet or contact a pharmacist.
Dosing: how much is usually taken
Dosing depends on your condition, age, other health issues, and how you tolerate NSAIDs. Your healthcare professional will advise the appropriate strength and schedule.
Common dosing patterns
- Adults: Often once daily, with adjustments based on response and safety considerations.
- Lower doses may be used first for those at higher risk of side effects (for example, history of stomach ulcers).
- Older adults: A more cautious approach may be used due to higher risk of adverse effects.
Important: Do not exceed the prescribed or labelled dose. Using higher doses or combining multiple NSAIDs increases the risk of harmful effects on the stomach, kidneys and heart/blood pressure.
Food interactions: what to know about taking Feldene with meals
NSAIDs can irritate the lining of the stomach. Food doesn’t remove all risk, but it can reduce stomach discomfort for some people.
- Taking with or after food: Often recommended to reduce stomach irritation.
- Avoid empty stomach use if it upsets you: If you notice nausea or burning, take it with meals.
- Hydration matters: Drink water regularly, especially if you are older or have kidney risk factors.
Alcohol and medicine interactions
Alcohol can increase the risk of stomach bleeding and may worsen irritation caused by NSAIDs. It can also affect the liver and increase side-effect severity.
Practical advice
- Try to avoid alcohol or keep it minimal while taking Feldene.
- If you drink regularly, ask a pharmacist or clinician for individual guidance.
- Seek urgent advice if you notice vomiting blood, black/tarry stools or severe abdominal pain.
Other common medicine interactions
Feldene can interact with other medicines, sometimes in important ways. The list below highlights common interactions. Always check with a pharmacist if you are taking multiple medicines.
Medicines to be cautious with
- Other NSAIDs (e.g., ibuprofen, naproxen, diclofenac): usually avoid combining due to increased bleeding risk.
- Low-dose aspirin: may be used, but increases GI bleeding risk; follow clinician advice.
- Anticoagulants (e.g., warfarin): increased bleeding risk.
- Antiplatelets (e.g., clopidogrel): increased bleeding risk.
- Corticosteroids (e.g., prednisolone): higher risk of stomach ulcer/bleeding.
- Selective serotonin reuptake inhibitors (SSRIs) (e.g., sertraline): may increase GI bleeding risk.
- Diuretics and blood pressure medicines (ACE inhibitors/ARBs): may affect kidney function and reduce effect of BP control in some patients.
- Lithium: NSAIDs can increase lithium levels.
- Methotrexate: interactions may occur affecting blood counts and toxicity.
- Digoxin: may increase digoxin levels in some cases.
- Phenytoin: may increase phenytoin levels.
This is not exhaustive. Please check your full medication list with a pharmacist, including over-the-counter products and herbal remedies.
Safety profile: side effects and what to watch for
Like all medicines, Feldene can cause side effects. Most people tolerate it well when used correctly, but some reactions can be serious.
Common side effects
- Indigestion or heartburn
- Nausea
- Stomach discomfort
- Headache
- Dizziness in some people
- Fluid retention (swelling in some cases)
Serious side effects – seek urgent medical help
Contact a healthcare professional urgently or seek emergency help if you experience:
- Signs of stomach/intestinal bleeding:
- vomiting blood
- black, tarry stools
- blood in stools
- severe or persistent stomach pain
- Allergic reactions (including anaphylaxis-like symptoms):
- swelling of the face, lips or throat
- breathing difficulties
- wheezing
- rash or blistering skin
- Severe skin reactions (rare)
- Kidney problems:
- reduced urine output
- unexplained swelling of legs/ankles
- unusual fatigue or breathlessness
- Heart and blood pressure concerns:
- chest pain
- shortness of breath
- significant increase in blood pressure
- Unexplained bruising or severe tiredness (rare blood-related effects)
Higher-risk patients
Your prescriber/pharmacist may consider alternative options or extra precautions if you have:
- a history of stomach ulcer or GI bleeding
- significant kidney disease
- uncontrolled high blood pressure or heart failure
- a history of asthma that worsens with NSAIDs
- ongoing use of blood thinners or multiple medicines that affect bleeding risk
- advanced age or frailty
Practical use tips for safer, more effective use
- Use the lowest effective dose for the shortest suitable duration (this is a general NSAID safety principle).
- Take with food if you experience stomach irritation.
- Avoid combining NSAIDs unless specifically instructed.
- Stay alert to “red flag” symptoms such as black stools, vomiting blood, unexplained bruising or rash.
- Maintain hydration, especially during hot weather or when unwell.
- Check interactions with any new medicine, including over-the-counter products.
- Don’t ignore persistent symptoms—if pain or inflammation continues, seek advice rather than increasing the dose on your own.
Alternative options (other pain and inflammation treatments)
Depending on the condition and your risk factors, alternatives may include:
Other NSAIDs
- For some people, a different NSAID may be better tolerated.
- However, all NSAIDs carry similar class-related risks (stomach bleeding, kidney effects and cardiovascular risk).
Non-NSAID pain relief
- Paracetamol (acetaminophen): can help with pain, though it does not provide the same anti-inflammatory effect.
- Topical anti-inflammatories (e.g., topical NSAIDs): may be helpful for some joint problems with lower systemic exposure.
Non-medicine approaches
- Physiotherapy and exercise programmes
- Heat/cold therapy
- Weight management (where relevant)
- Joint support, pacing activity and ergonomic adjustments
For chronic inflammatory conditions, your clinician may also consider disease-specific treatments (for example, therapies that target the underlying condition), not only symptom relief.
