The drug comes in pill form in both 10 and 20 milligram (mg) doses and is taken orally. It is available in the generic form as piroxicam and in the brand name form as Feldene.
Uses
Piroxicam is approved to treat osteoarthritis and rheumatoid arthritis. Sometimes piroxicam is prescribed off label to treat gouty arthritis and ankylosing spondylitis. It has also been proven effective at treating migraines without aura.
You may also be prescribed piroxicam or Feldene post-surgery or childbirth or to help you manage the pain caused by menstrual cramps.
Before Taking
When prescribing Piroxicam your healthcare provider will evaluate your disease state and levels of pain. Talk to your healthcare provider about all medications, supplements, and vitamins that you currently take.
While some drugs pose minor interaction risks, others may outright contraindicate use or prompt careful consideration as to whether the pros of treatment outweigh the cons in your case.
If you have osteoarthritis or rheumatoid arthritis your healthcare provider may start you on a low dose and work your way up to the maximum dose needed to achieve relief. Feldene has a long half-life and can take up to seven to 12 days before the benefits of the drug are felt.
You may need to be reassessed by your healthcare provider after beginning the medication to ensure that it is working.
Precautions and Contraindications
While piroxicam can help relieve the pain associated with osteoarthritis and rheumatoid arthritis there are certain instances when taking the drug may pose more risks for you.
If you have a history of asthma, hives, or other allergic reactions to aspirin or other NSAIDs, it is not recommended you take piroxicam or Feldene. Anyone over the age of 75 may also find that piroxicam is not the right fit for them.
Taking piroxicam, and other prescription NSAIDs can increase your risk of having a heart attack or stroke. This risk may be higher if you take NSAIDs for long periods of time. Do not take piroxicam if you have recently had a heart attack unless your healthcare provider has approved its use.
If you are scheduled for a coronary artery bypass graft, you should not take piroxicam right before or right after surgery.
For females who are experiencing difficulties in conceiving, use of piroxicam is not recommended as NSAIDs, including Feldene, can cause a reversible delay in ovulation.
Other NSAIDs
There are many other NSAIDs, both prescription and over the counter that may be helpful for your condition. It is important to talk to your healthcare provider about the right choice for you. Other NSAIDs that treat pain, inflammation, swelling, and tenderness, especially when caused by arthritis, are:
Advil (ibuprofen) Aleve (naproxen sodium) Etodolac Zorvolex (diclofenac)
Dosage
The maximum dosage for piroxicam according to the manufacturer is 20 mg a day. This can be taken in once-daily pills of 20 mg each or divided into two doses of 10 mg each.
When prescribed piroxicam or any other medication, it is important to follow the directions on your prescription label carefully. If you have any questions, ask your healthcare provider or pharmacist to explain anything you do not understand.
How to Take and Store
Take piroxicam as directed. If you miss a dose of piroxicam, take the next dose as soon as you remember. However, if it is almost time to take your next dose skip the missed dose and return to your regular schedule. Do not take a double dose.
You may also want to take the drug with food to reduce the incidence of adverse gastrointestinal effects.
