Feldene (Piroxicam) – Patient Information Guide (UK)

Feldene is the brand name of piroxicam, a medicine from the group of non-steroidal anti-inflammatory drugs (NSAIDs). It is used to reduce pain and inflammation associated with a number of musculoskeletal conditions. This page explains how Feldene works, how it is taken, common side effects and safety points, and how it compares with other treatment options.

Always follow the instructions given by your healthcare professional and the information on the package. If you are unsure about anything, speak to a pharmacist.

1) Basic Product Information

What NSAIDs do: They help relieve symptoms such as pain, swelling and stiffness by lowering production of certain substances in the body involved in inflammation.

2) How Feldene Works (Mechanism of Action)

Piroxicam works by blocking enzymes called cyclo-oxygenase (COX-1 and COX-2). These enzymes are involved in making prostaglandins, chemical messengers that contribute to:

• Inflammation (swelling and redness)
• Pain signalling
• Fever (in some conditions)
• Protection of the stomach lining (mainly via COX-1)

Because NSAIDs can reduce prostaglandins throughout the body, they may provide symptom relief but can also increase the risk of certain side effects, especially affecting the stomach, kidneys and cardiovascular system. This is why using the lowest effective dose for the shortest possible duration is generally recommended.

3) Pharmacokinetics (How the Body Handles Piroxicam)

Pharmacokinetics describes what the body does to a medicine—how it is absorbed, distributed, metabolised and eliminated.

• Absorption: Piroxicam is absorbed from the gut after swallowing. Peak levels typically occur after a number of hours (often several hours, depending on the formulation and individual factors).
• Distribution: It is highly bound to plasma proteins, meaning much of the medicine travels in the bloodstream attached to proteins.
• Metabolism: The medicine is metabolised mainly by the liver.
• Elimination: It is excreted primarily as metabolites via the kidneys and bile.
• Half-life / duration: Piroxicam has a relatively long half-life, which is one reason it is often taken once daily in many regimens.

If you have liver or kidney problems, your prescriber may choose a different approach or require closer monitoring.

4) Typical Use in the UK

Feldene is used to treat conditions where inflammation contributes to pain and stiffness. Common examples include:

• Inflammatory and degenerative joint diseases, such as osteoarthritis and rheumatoid arthritis
• Other musculoskeletal disorders where an anti-inflammatory pain reliever is appropriate
• Longer-term symptom control in some chronic conditions (depending on your circumstances)

It may take time to feel the full benefit. Some people notice improvement within days, while others require longer. If symptoms do not improve, or if they worsen, seek advice.

5) When and How to Take Feldene (Timing and Practical Use)

How often

Piroxicam is commonly taken once daily. However, your exact schedule may differ depending on your diagnosis, age, other medicines and risk factors.

What time of day?

Choose a time that you can manage consistently. Many people prefer taking it at the same time each day to maintain steady effect. Some people find taking it after food helps reduce stomach discomfort.

With food or without?

Taking Feldene with food (or milk) may help limit stomach irritation. Food does not usually “cancel out” the effect, but it can reduce the chance of nausea or indigestion for some individuals.

Swallowing tips

• Swallow tablets whole with water—do not crush or chew unless instructed otherwise.
• If you miss a dose, take it when you remember unless it is close to the next dose. Do not take a double dose.

Do not stop suddenly without advice if you have been taking it regularly for chronic symptoms, because your pain and inflammation may return.

6) Food Interactions

General guidance: Food can influence comfort rather than safety in most cases. Taking Feldene after meals is often recommended to reduce gastrointestinal irritation.

• Milk/food: May help reduce indigestion or nausea for some people.
• Alcohol with NSAIDs: See the alcohol section below—alcohol can increase bleeding risk in the stomach.
• Hydration: Staying well hydrated supports kidney function, particularly important when taking NSAIDs.

7) Alcohol and Medicine Interactions

Alcohol

It is generally recommended to avoid or minimise alcohol while taking NSAIDs like piroxicam, because alcohol can increase the risk of stomach irritation and bleeding. If you do drink alcohol, do so cautiously and in line with NHS guidance.

Other medicines that may interact

Tell your pharmacist or healthcare professional about all medicines you use, including over-the-counter products and herbal remedies. Important interactions include:

• Other NSAIDs (e.g., ibuprofen, naproxen, diclofenac, aspirin for pain):
  Using multiple NSAIDs together increases risk of stomach bleeding and kidney problems.
• Blood thinners (e.g., warfarin) and antiplatelet medicines (e.g., clopidogrel):
  NSAIDs can increase bleeding risk.
• Low-dose aspirin:
  Aspirin may be prescribed for heart protection. Combining with NSAIDs can still increase gastrointestinal risk—only take together under medical advice.
• SSRIs/SNRIs used for depression/anxiety (e.g., sertraline, citalopram, venlafaxine):
  These can increase bleeding risk in combination with NSAIDs.
• Corticosteroids (e.g., prednisolone):
  Higher risk of stomach ulceration/bleeding.
• Diuretics (“water tablets”) and medicines affecting blood pressure (e.g., ACE inhibitors such as lisinopril, and ARBs such as losartan):
  The combination can affect kidney function. Monitoring may be needed, particularly in older adults or those with kidney disease.
• Lithium:
  NSAIDs may raise lithium levels, increasing toxicity risk.
• Methotrexate (used in some inflammatory conditions and cancer treatment):
  NSAIDs can affect methotrexate levels and increase side effects, particularly at higher methotrexate doses.
• Digoxin:
  There is potential for changes in digoxin levels.
• Diabetes medicines (e.g., insulin or sulfonylureas):
  NSAIDs may affect blood glucose in some people.

This is not a complete list. Your pharmacist can check interactions with your specific medicines and conditions.

8) Indications (What Feldene is Used For)

Indications vary by product licence details and local clinical practice, but piroxicam is commonly prescribed for:

• Osteoarthritis (pain and stiffness from wear-and-tear joint disease)
• Rheumatoid arthritis (inflammatory joint condition)
• Other inflammatory musculoskeletal conditions where an NSAID is appropriate

Your healthcare professional will consider factors such as your medical history, other risk factors (for example, heart disease, ulcers, kidney problems), and whether safer alternatives might be better for you.

9) Dosing (Usual Amounts and Important Safety Principles)

Only use the dose recommended for you. Individual dosing depends on the condition being treated, tolerability, and overall risk. Common adult dosing regimens in the UK for piroxicam may include once-daily dosing, with total daily dose typically within a defined range (often 10–20 mg/day depending on the product and clinical scenario).

General dosing principles

• Start low: Many clinicians aim for the lowest effective dose.
• Use the shortest duration: Reduce exposure time when possible.
• Monitor: If you require ongoing treatment, periodic review is important.
• Do not combine NSAIDs: Avoid taking Feldene with other NSAIDs unless specifically advised.

If you have specific risk factors

Your prescriber may recommend a different dose or a different medicine if you have:

• History of stomach ulcers or gastrointestinal bleeding
• Kidney impairment
• Heart disease or a history of stroke
• Significant fluid retention or uncontrolled high blood pressure

Children and adolescents: Feldene is generally intended for adults in many settings. Use in younger people depends on the specific product licence and clinical judgement. Always follow professional advice for age-appropriate use.

10) Safety Profile (Common Side Effects and Warnings)

Like all medicines, Feldene (piroxicam) can cause side effects. Many people tolerate NSAIDs well, but the risk of serious side effects is higher in certain groups (especially older adults and people with stomach or kidney problems).

Common side effects

• Indigestion, heartburn
• Nausea
• Abdominal discomfort
• Headache or dizziness (occasionally)

Serious side effects – seek urgent help

Stop taking Feldene and seek urgent medical advice if you experience:

• Signs of stomach bleeding such as black/tarry stools, vomiting blood, or severe persistent stomach pain
• Allergic reactions including swelling of the face/lips, wheezing, or rash with breathing difficulty
• Breathing problems or asthma flare after NSAID use
• Chest pain, sudden weakness or numbness, or shortness of breath (possible cardiovascular or stroke symptoms)
• Reduced urine output, severe swelling, or sudden worsening kidney symptoms
• Severe skin reactions (rare): widespread rash, blistering, or peeling skin

Who needs extra caution?

• People aged 65 years and over
• Those with a history of peptic ulcer or gastrointestinal bleeding
• Those taking medicines that increase bleeding risk (blood thinners, certain antidepressants, corticosteroids)
• People with kidney disease, dehydration, or low blood volume
• People with heart failure, ischemic heart disease, or previous stroke
• Anyone with uncontrolled hypertension

11) Practical Use Tips for Safer Treatment

• Take after food to reduce stomach upset.
• Use the lowest effective dose and review need regularly.
• Avoid other NSAIDs (including “for cold and flu” products that may contain anti-inflammatory painkillers).
• Check your full medicine list for interactions, including over-the-counter products.
• Stay hydrated, especially if you’re elderly or unwell with vomiting/diarrhoea.
• Watch for warning symptoms (black stools, severe indigestion, swelling, unusual breathlessness).
• Don’t drink heavily; alcohol increases stomach bleeding risk.

If you are taking Feldene long-term, healthcare providers may advise periodic checks (for example, kidney function and blood pressure). Ask your pharmacist what monitoring is appropriate for you.

12) Alternative Options

Pain and inflammation can often be managed with other approaches depending on the underlying condition, your risk factors, and your preferences. Alternatives include:

Other medicines

• Paracetamol (acetaminophen) for pain relief (does not reduce inflammation, but may be safer for some people).
• Other NSAIDs (e.g., ibuprofen, naproxen, diclofenac):
  They work similarly but can differ in side effect risk and suitability for individual patients. Do not combine different NSAIDs together.
• Topical NSAIDs (e.g., gels/creams such as diclofenac):
  These may be an option for certain joint pains and can reduce systemic exposure.

Non-medicine approaches

• Physiotherapy and exercise (often beneficial for long-term joint health)
• Weight management for osteoarthritis symptoms
• Heat/cold therapy and activity modification
• Supportive aids (e.g., braces or footwear adjustments) depending on the condition

Your healthcare professional can help choose the most suitable option by weighing benefits against risks for your particular health history.

13) Market and Legal Context in the UK

In the UK, medicines like piroxicam are regulated and must meet safety standards set by UK medicines authorities. NSAIDs are widely used, and UK clinical guidance emphasises:

• Risk assessment before and during NSAID therapy
• Appropriate duration and lowest effective dose
• Consideration of stomach protection in higher-risk patients (as advised by healthcare professionals)
• Attention to cardiovascular and kidney risks, especially in vulnerable groups

Guidance and safety communications can change over time. If you have concerns, consult a pharmacist or check the latest NHS advice relevant to NSAIDs and stomach protection.

14) Recent Guidance (What UK Advice Commonly Highlights)

Across the UK, recent safety messaging and clinical practice have consistently reinforced:

• Avoid unnecessary NSAID use and review ongoing need.
• Take with food and monitor for gastrointestinal symptoms.
• Be cautious with combination medicines that increase bleeding risk (including some antidepressants).
• Recognise higher risk groups, including older adults and people with a history of ulcer/bleeding.
• Seek medical advice early if red-flag symptoms appear.

If you’re unsure whether Feldene is appropriate for you, a pharmacist can help you understand risk factors and possible safer alternatives.

16) FAQ – Frequently Asked Questions

How quickly will Feldene work?

Some people notice symptom improvement within a few days, but full benefit—especially for conditions like arthritis—may take longer. If there’s no improvement or symptoms worsen, seek advice.

Can I take Feldene with food?

Yes. Many people find taking Feldene after food reduces stomach discomfort. If your stomach is sensitive, this is often the preferred approach.

Is Feldene safe for long-term use?

It may be used long-term for certain chronic conditions, but NSAIDs can carry ongoing risks (stomach, kidney and cardiovascular). Your treatment should be reviewed regularly, using the lowest effective dose and duration.

Can I take ibuprofen or another NSAID as well?

Generally, avoid combining NSAIDs. Using multiple NSAIDs together increases risk of side effects such as stomach bleeding and kidney problems. If another painkiller is needed, speak to a pharmacist about safer options.

What should I do if I miss a dose?

Take it when you remember unless it’s close to your next dose. Do not take a double dose to make up for the missed one.

Can I drink alcohol while taking Feldene?

It’s best to avoid or minimise alcohol because alcohol can increase the risk of stomach irritation and bleeding when combined with NSAIDs.

What are the warning signs of stomach problems?

Watch for persistent indigestion, severe stomach pain, vomiting blood, or black/tarry stools. These can indicate bleeding and require urgent medical advice.

Who should not take Feldene?

NSAIDs may not be suitable for everyone, particularly those with a history of NSAID-triggered allergic reactions, active ulcers, previous gastrointestinal bleeding, or significant kidney disease. A pharmacist can help you check suitability based on your history and current medicines.

Are there alternatives if I can’t tolerate NSAIDs?

Options can include paracetamol for pain, topical NSAIDs for localized joint pain, or non-medicine strategies such as physiotherapy and exercise. The best choice depends on your condition and risk factors.

Can Feldene affect my blood pressure or kidneys?

Yes, NSAIDs can affect kidney function and may worsen blood pressure in some people. If you have kidney disease, heart failure, are dehydrated, or take blood pressure medicines, extra caution is needed.
