Feldene (Piroxicam) Capsules 10 mg & 20 mg

Feldene capsules stand apart from most everyday anti-inflammatory painkillers for one specific reason: piroxicam, the active ingredient, has one of the longest elimination half-lives of any oral NSAID, which supports once-daily dosing for sustained control of joint symptoms. That same long half-life is also why Feldene is positioned as a second-line option for specific rheumatic conditions rather than a first-choice, short-term painkiller - a distinction worth understanding before you compare it with faster-clearing NSAIDs such as naproxen or ibuprofen. The practical consequence is straightforward: fewer dosing times to remember each day, but a medicine that takes longer to build up and longer to clear if it does not suit you, which is exactly why dosing, monitoring and duration of use matter more here than with a typical short-acting painkiller.

What Feldene capsules are and where they fit

Feldene is the branded capsule form of piroxicam, a non-steroidal anti-inflammatory drug (NSAID) taken by mouth. We supply it as 10 mg and 20 mg capsules, and both strengths deliver the same active ingredient at different doses rather than different formulations, so choosing between them is a matter of following the prescribed dose, not changing medicines. Piroxicam belongs to the oxicam class of NSAIDs and is established for the symptomatic relief of chronic inflammatory and degenerative joint disease, principally osteoarthritis, rheumatoid arthritis and ankylosing spondylitis. It does not treat the underlying joint damage; it reduces the pain, swelling and stiffness that these conditions cause, which is why it is generally prescribed alongside a wider management plan rather than as a stand-alone cure.

The main purchasing distinction is therefore not simply whether piroxicam can relieve pain. It is whether its long duration and once-daily schedule offer a worthwhile practical benefit after a clinician has considered safer first-line options, gastrointestinal history, cardiovascular and kidney risks, other medicines, and the need for follow-up. A familiar brand name or convenient schedule should not outweigh those suitability questions.

Who should consider Feldene capsules?

Feldene tends to suit adults with an established diagnosis of osteoarthritis, rheumatoid arthritis or ankylosing spondylitis whose symptoms have not been adequately controlled by, or who cannot tolerate, other NSAIDs, and whose prescriber has weighed the gastrointestinal and skin-reaction risks against the expected benefit. It is not usually the first NSAID tried for a new complaint.

• Adults with chronic osteoarthritis pain and stiffness affecting daily function.
• Adults with rheumatoid arthritis needing sustained anti-inflammatory control.
• Adults with ankylosing spondylitis for whom once-daily dosing may support adherence.
• People who have already discussed second-line NSAID options with a clinician.

Piroxicam is not recommended for children or adolescents. It is contraindicated during the third trimester of pregnancy and should not be used in the first or second trimester unless clearly necessary; it should also be avoided while breastfeeding. Anyone trying to conceive should discuss treatment because NSAIDs may impair female fertility. People with a history of asthma, nasal polyps, angioedema or urticaria triggered by aspirin or another NSAID must not take piroxicam. We return to these and other suitability points in the safety section below.

How does piroxicam work once you start taking it?

Piroxicam works by inhibiting cyclo-oxygenase (COX-1 and COX-2) enzymes, which reduces the production of prostaglandins involved in inflammation, pain signalling and fever. Because it inhibits both COX isoforms rather than selectively targeting COX-2, it carries the gastrointestinal risk profile typical of older non-selective NSAIDs.

In practical terms, some easing of pain may be felt within the first few days, but the fuller anti-inflammatory effect on joint swelling and morning stiffness can take one to two weeks of consistent daily dosing to become clear as piroxicam accumulates towards steady levels. Individual response varies, so the useful test is not only whether pain changes after one dose but whether movement, stiffness and daily function improve over an agreed review period without unacceptable adverse effects.

How to take Feldene and build it into a routine

Piroxicam capsules are usually taken once daily and swallowed whole with water. Taking them with or after food may reduce stomach upset, although food does not remove the risk of an ulcer or gastrointestinal bleeding. The usual adult dose is 20 mg daily, taken as a single dose or divided if specifically directed, and the maximum recommended daily dose is 20 mg. The lowest effective dose should be used for the shortest period a prescriber judges appropriate.

Take the prescribed number and strength of capsules at the same time each day to make the routine easier to remember. If a dose is missed, take it when remembered unless it is nearly time for the next dose; in that case, skip the missed dose and continue as usual. Do not take a double dose. Because piroxicam stays in the body for longer than most NSAIDs, changes in dose or discontinuation should be discussed with a prescriber rather than made independently.

• Check whether the directions specify one 20 mg capsule, two 10 mg capsules, or another clinician-directed schedule.
• Do not add ibuprofen, naproxen, aspirin for pain relief, or another NSAID unless a clinician has explicitly advised it.
• Avoid excessive alcohol because it can add to stomach irritation and bleeding risk.
• Keep hydrated, particularly during illness, vomiting or diarrhoea, when NSAID-related kidney effects can become more likely.

Choosing between the strengths and pack sizes we offer

We currently stock Feldene capsules in the following combinations, so you can match the strength and quantity to what your prescriber has specified:

• 10 mg capsules in packs of 30, 60, 90, 120, 180 or 360 capsules.
• 20 mg capsules in packs of 60, 90, 120, 180, 270 or 360 capsules.

The two strengths may support different prescribed arrangements, but they should not be exchanged capsule for capsule. For example, two 10 mg capsules contain the same total amount of piroxicam as one 20 mg capsule, while one 10 mg capsule does not. Confirm the strength, number of capsules per dose and total quantity rather than relying on pack appearance alone.

Choosing the right pack size is mainly a question of matching the quantity to the length of treatment agreed with your prescriber, since piroxicam should be reviewed periodically rather than taken indefinitely without reassessment. A larger pack may be convenient for an established routine only when it matches the authorised treatment quantity and review plan. A smaller pack may be more appropriate for an initial supply or treatment period due for early review.

What to expect and how quickly

Some people notice a reduction in pain within the first few days of starting piroxicam, with the fuller anti-inflammatory benefit - less morning stiffness, less swelling and easier movement - becoming clearer after one to two weeks of regular dosing. Not everyone responds, and the aim is a meaningful improvement in function or symptom control rather than the complete removal of every joint symptom.

Because of the long half-life, effects last well beyond a single dose, which supports the usual once-daily schedule but means adverse effects can also persist after treatment is stopped. Prescribers typically review treatment at intervals to confirm that the benefit still outweighs the risk. Seek advice rather than increasing the dose if symptoms remain uncontrolled, because exceeding 20 mg daily raises risk without being an appropriate way to accelerate the response.

What are the main safety priorities with Feldene?

Piroxicam's main risks are gastrointestinal ulceration or bleeding and, less commonly but seriously, severe skin reactions. It is therefore reserved for second-line use, with treatment initiated by a clinician experienced in assessing inflammatory or degenerative rheumatic disease and with appropriate monitoring.

• People with an active peptic ulcer or a history of recurrent gastrointestinal ulceration, bleeding or perforation.
• People with asthma, nasal polyps, angioedema, urticaria or a previous reaction triggered by aspirin or another NSAID.
• Anyone in the third trimester of pregnancy, as well as people who are breastfeeding.
• Children and adolescents, for whom oral piroxicam capsules are not recommended.
• People with severe heart failure or severe kidney or liver impairment.
• People with cardiovascular disease, high blood pressure, fluid retention, diabetes or kidney problems who require individual risk assessment and closer monitoring.

Effects such as indigestion, heartburn, headache or dizziness may be non-urgent, but they should be discussed with a doctor or pharmacist if they persist, worsen or are troublesome. Black or tarry stools, vomiting blood, severe abdominal pain, a sudden rash, blistering or peeling skin, mouth ulcers, breathlessness, chest pain, weakness on one side, or swelling of the face and throat require urgent medical attention. Stop taking piroxicam and seek immediate advice if signs of gastrointestinal bleeding, a severe skin reaction or a serious allergic reaction occur.

Severe skin reactions are most likely early in treatment, particularly during the first month. Piroxicam can also cause dizziness, drowsiness, fatigue or visual disturbance strong enough to affect driving or operating machinery, so do not do either if affected.

Interactions and practical precautions

Piroxicam is highly protein-bound and interacts with a number of other medicines. Give the prescriber and pharmacist a complete list of prescription medicines, over-the-counter products and supplements before starting treatment, and check before adding anything new.

• Aspirin, other NSAIDs or high-dose salicylates, which increase gastrointestinal and bleeding risk when combined.
• Warfarin and other anticoagulants, antiplatelet medicines, corticosteroids and SSRIs, which can further increase bleeding risk.
• Lithium and methotrexate, whose blood levels or toxicity piroxicam can increase.
• ACE inhibitors, angiotensin receptor blockers and diuretics, where combined use can affect kidney function and blood pressure control.
• Sulfonylureas and other oral medicines for diabetes, because glucose control may require closer monitoring.
• Ciclosporin or tacrolimus, where combining kidney-related effects can increase the risk of renal toxicity.

Monitoring during ongoing treatment commonly includes blood pressure and kidney function, with liver tests, blood counts or blood glucose checks where clinically relevant. Report ankle swelling, an unexplained change in weight, reduced urine output, unusual bruising, persistent tiredness or worsening breathlessness rather than waiting for a routine review.

How does Feldene compare with Naproxen?

Naproxen is a frequently used oral NSAID and offers a useful point of comparison, since both medicines are taken by mouth for inflammatory joint symptoms but differ meaningfully in duration, dosing pattern and place in treatment.

In broad terms, naproxen has a shorter half-life and is often taken in divided doses, which allows it to clear more quickly if adverse effects appear. Piroxicam's longer half-life supports once-daily dosing, but it is a second-line choice because of its gastrointestinal and serious skin-reaction risks. Dosing convenience alone is therefore not a reason to choose piroxicam when another NSAID provides adequate control with a more suitable risk profile.

For people discussing gastrointestinal tolerability, a COX-2 selective option such as Celecoxib (Celebrex) may also be considered, although COX-2 selectivity does not remove cardiovascular, kidney or all gastrointestinal risks. Those comparing medicines within the oxicam class may discuss piroxicam with meloxicam, sold under the brand Mobic (Mobic). None of these switches should be made without medical advice, since each NSAID has its own contraindications, interactions and balance of benefit and risk.

Feldene's status and how we handle orders in the UK

Piroxicam is classified as a prescription-only medicine in the United Kingdom. Its use is restricted to second-line symptomatic relief of osteoarthritis, rheumatoid arthritis or ankylosing spondylitis after an individual risk assessment. That regulatory classification is separate from our ordering policy: we do not require you to upload or post a prescription for us to accept an order for Feldene.

Our checkout policy does not replace medical assessment. Anyone starting piroxicam, changing strength or resuming it after a break should discuss suitability with a doctor or pharmacist because the decision depends on medical history, current medicines and monitoring needs. Suspected adverse effects can be reported through the MHRA Yellow Card Scheme, which helps the regulator monitor medicine safety in routine use.

Making your decision

Choosing Feldene capsules comes down to whether once-daily dosing and a long-established second-line NSAID profile fit your situation better than a faster-clearing alternative such as naproxen or a COX-2 selective option. The strongest reason to consider it is sustained symptom control with a simple dosing schedule after individual risk assessment; the strongest reason to consider another option is piroxicam's comparatively important gastrointestinal and serious skin-reaction risk.

We stock both 10 mg and 20 mg capsules across the listed pack quantities, and our ordering policy does not require a prescription to be submitted at checkout. Before ordering, confirm the prescribed strength, dose and quantity, consider when treatment is due for review, and check for interacting medicines or contraindications. Our support team is available around the clock if you need practical help matching the available option to your prescriber's plan.
