Feldene (Piroxicam) Capsules 10 mg and 20 mg

Piroxicam's long half-life is the single fact that separates Feldene from most other anti-inflammatory capsules on our shelves: one daily dose can provide sustained coverage, which suits people who forget a lunchtime tablet or who simply want fewer moving parts in their day. That convenience comes with a trade-off worth understanding before you compare it against shorter-acting NSAIDs, and this guide works through that trade-off alongside dosing, safety, alternatives, and how ordering and delivery work through our pharmacy.

What Feldene is and how it fits into NSAID therapy

Feldene is the brand name for piroxicam, a non-steroidal anti-inflammatory drug (NSAID) supplied as an oral capsule. We offer it in 10 mg and 20 mg strengths, which support prescribed dosing across established arthritis therapy. Piroxicam belongs to the oxicam class of NSAIDs, distinguished chemically from ibuprofen, naproxen, and diclofenac, though it shares the same broad mechanism: it inhibits cyclo-oxygenase (COX) enzymes and reduces the production of prostaglandins involved in inflammation, pain, and joint swelling. Because piroxicam is cleared from the body slowly, it is commonly prescribed once daily, although the exact dose and schedule should follow the prescriber's directions.

Who should consider Feldene capsules?

Piroxicam is established for the symptomatic relief of osteoarthritis, rheumatoid arthritis, and ankylosing spondylitis in adults. It may suit people with persistent joint pain and stiffness who want a simple once-a-day capsule rather than multiple doses spread through the day. It is not the right starting choice for everyone, and a few groups should think carefully before choosing it over another option:

• People with a history of stomach ulcers or gastrointestinal bleeding, since piroxicam has a significant gastrointestinal risk that needs to be weighed against its benefits.
• People who have had asthma, hives, or an allergic-type reaction after taking aspirin or another NSAID, because cross-reactivity is a recognised risk.
• Pregnant women, particularly in the third trimester, when NSAIDs including piroxicam are contraindicated. Use earlier in pregnancy should occur only when a prescriber considers it clearly necessary.
• People who are breastfeeding, as piroxicam passes into breast milk and is not recommended for nursing mothers.
• People with reduced kidney function, heart failure, or diabetes-related kidney changes, where NSAID effects on renal blood flow need closer attention.
• Anyone under 18, since piroxicam's safety and effectiveness have not been established in that age group.

If you fall into one of the categories above, a conversation with your prescriber about a shorter-acting NSAID or a different drug class is worthwhile before you commit to a Feldene order.

How does piroxicam relieve joint pain and stiffness?

Inflammation in osteoarthritis and rheumatoid arthritis is driven partly by prostaglandins produced through the COX-1 and COX-2 pathways. Piroxicam blocks both, reducing the swelling, warmth, and pain signalling that make joints stiff and difficult to move. Because it inhibits COX-1 as well as COX-2, it also reduces protective prostaglandins that support the stomach lining, which is a main reason gastrointestinal side effects are a standing consideration with this medicine, as with other non-selective NSAIDs. In practical terms, piroxicam reduces inflammatory symptoms but does not cure arthritis or alter the underlying progression of the disease. Its systemic effects can also involve the gut, kidneys, cardiovascular system, and platelets.

Building a daily routine with Feldene capsules

Piroxicam capsules may be taken with food or milk if they upset the stomach, and should be swallowed with water according to the supplied directions. Taking a prescribed once-daily dose at the same time each day can make the routine easier to remember. Because piroxicam takes roughly seven to twelve days to reach a stable level in the blood, doses should not be doubled or adjusted without medical advice if relief feels slow to start - a rushed increase raises side-effect risk without necessarily speeding up benefit. Adult dosing is individualised, with a usual maximum of 20 mg per day; use the lowest effective dose for the shortest duration appropriate to the condition. We package both strengths separately so that a prescribed dose change can be managed by switching strength rather than splitting capsules.

Strengths and pack sizes we offer

We list Feldene capsules in the following combinations, so you can match a pack to how long a course is expected to run:

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

Larger packs generally work out more cost-effective per capsule for people on an established, ongoing regimen, while smaller packs suit someone starting piroxicam for the first time or trialling a new strength before committing to a bigger order.

What can you expect, and when might relief begin?

Some easing of pain can appear within the first few days, but the fuller anti-inflammatory effect - such as less morning stiffness and better joint movement - may build over one to two weeks as piroxicam approaches steady levels in the body. This gradual build-up is worth expecting rather than immediately reading it as a sign the capsule is not working. Once established, its long half-life can provide relatively consistent day-to-day coverage compared with some shorter-acting NSAIDs. If pain or stiffness has not improved meaningfully after two to three weeks of consistent prescribed use, revisit the plan with a prescriber rather than persisting indefinitely.

Safety priorities to know before you start

Piroxicam remains in the body for a long time, so adverse effects may not resolve immediately after a dose is stopped. It pays to know what may be manageable and what needs prompt attention.

Common effects include indigestion, mild stomach discomfort, headache, and dizziness. More serious warning signs include black or bloody stools, vomiting blood, severe or worsening stomach pain, unexplained swelling or shortness of breath, and any skin rash, blistering, or peeling - serious skin reactions are taken particularly seriously with piroxicam and warrant stopping the capsule and seeking medical care promptly. Piroxicam should not be used in people with active gastrointestinal bleeding or ulceration, severe heart failure, severe kidney or liver impairment, or a previous serious reaction to piroxicam, aspirin, or another NSAID. Regular use for more than a few weeks is usually paired with periodic checks of kidney function, blood pressure, and, in some cases, liver function or blood counts, particularly for people already managing other health conditions.

Interactions and practical precautions

Piroxicam can interact meaningfully with several other medicines, so a full list of what you're already taking is worth having ready before starting:

• Other NSAIDs or aspirin- combining them increases gastrointestinal and bleeding risk without usually adding benefit.
• Anticoagulants such as warfarin and antiplatelet medicines- combining them with piroxicam can substantially increase bleeding risk and may require avoidance or close monitoring.
• Lithium and methotrexate- piroxicam can reduce their clearance, raising blood levels and toxicity risk.
• ACE inhibitors, ARBs, and diuretics- the combination can reduce kidney blood flow, increase the risk of kidney injury, and blunt blood-pressure control.
• Corticosteroids and SSRIs- both further increase gastrointestinal bleeding risk when combined with an NSAID.
• Sulfonylureas and other glucose-lowering medicines- blood glucose may need closer monitoring, especially where diabetes-related kidney impairment is present.

Alcohol adds to stomach irritation and bleeding risk and is worth limiting while taking piroxicam. Because dizziness, drowsiness, or visual disturbance can occur, take care with driving or operating machinery until you know how the capsule affects you.

Feldene compared with Naprosyn and Celebrex

Piroxicam is one of several NSAIDs used for osteoarthritis and rheumatoid arthritis, and the right choice often comes down to how a person tolerates gastrointestinal effects, how many daily doses they want to manage, and whether cardiovascular, kidney, or stomach risk needs to be minimised. The comparisons below set Feldene against two commonly considered alternatives.

Naprosyn (naproxen) is also a non-selective NSAID, but its half-life is shorter than piroxicam's, so it is commonly dosed more than once daily depending on the formulation and prescribed regimen. Some prescribers favour naproxen for its comparatively well-studied cardiovascular profile, while piroxicam's commonly once-daily routine may appeal to people who prioritise dosing simplicity.

Celebrex (celecoxib) works differently: it selectively targets COX-2 rather than both COX-1 and COX-2, which generally means less impact on stomach-protective prostaglandins and a lower risk of some gastrointestinal complications than with a non-selective NSAID such as piroxicam. Celecoxib still carries gastrointestinal, cardiovascular, and kidney risks, so the choice depends on the individual's overall risk profile rather than one factor alone. People who have had stomach problems on non-selective NSAIDs may be considered for celecoxib, while others may value piroxicam's established once-daily simplicity. Meloxicam, sold under the brand Mobic, sits somewhere between the two: it is also commonly taken once daily and has some COX-2 preference without being as selective as celecoxib. It is another option worth discussing with a prescriber if piroxicam does not suit you. You can also browse our Arthritis section for other relevant options.

Prescription status and access in Australia

Piroxicam is classified as a Schedule 4 prescription-only medicine in Australia, meaning it legally requires a valid prescription from an authorised prescriber. That classification sits separately from our own ordering process: our ordering policy does not require you to upload or send us a prescription before we accept your Feldene order. This does not change piroxicam's regulatory status in Australia, and medical advice remains important before starting or continuing it given its contraindications, interactions, and adverse-effect profile. Whether a particular Feldene product is PBS-subsidised depends on the specific strength, indication, and prescribing conditions listed on the Pharmaceutical Benefits Scheme, so it is worth checking current PBS listings if subsidised pricing matters to your decision.

Ordering, delivery, and receiving your order

We've operated our online pharmacy catalogue since 2018, and our support team is reachable every day of the week by email or online chat, with a pharmacist available to answer questions about Feldene or any other order. Prices are shown in Australian dollars, and once an order is placed we pack and dispatch it promptly, with delivery timeframes presented as estimates at checkout so you can plan around them rather than guess. Because piroxicam capsules should be stored at 20°C to 25°C, with excursions between 15°C and 30°C permitted, protected from light, and kept in a tightly closed container, it is worth having a suitable storage spot ready before your pack arrives rather than leaving capsules in a hot car or on a sunny windowsill.

Making your decision

Feldene may suit someone who wants a commonly once-daily NSAID capsule for osteoarthritis, rheumatoid arthritis, or ankylosing spondylitis and whose prescriber considers its benefits appropriate in light of their gastrointestinal, cardiovascular, kidney, and allergy risks. A few points are worth checking off before you finalise a pack size and place an order:

1. Confirm with a prescriber that piroxicam, rather than a shorter-acting NSAID or a COX-2 selective option, fits your health history.
2. Decide between the 10 mg and 20 mg strength based on the dose your prescriber recommends.
3. Choose a pack size that matches how long you expect to continue treatment, since larger packs suit an established, ongoing routine.
4. Plan a storage spot that stays within the recommended temperature range and protects the capsules from light.
5. Keep a note of any other medicines you take, particularly anticoagulants, lithium, methotrexate, or blood-pressure medicines, so interactions can be checked.

With those points settled, choosing between Feldene's 10 mg and 20 mg capsules and one of the pack sizes we list becomes a straightforward step, and our support team remains available if any question comes up before or after you order.
